JP 2012-170706 A

Here, the above-mentioned water heating container is configured such that the upper opening of the container main body having a storage portion inside is closed in a sealed state by a lid, and the dispensing flow path is also closed in a sealed state by a valve mechanism. Has been. On the other hand, when the container main body is inclined, that is, when the axis of the container main body is inclined more than a predetermined water-stop angle with respect to the vertical direction, the steam flow path has a weight of the falling water stop valve. It is configured to be closed by the body.
Therefore, the user grips the handle, and tries to pour hot water in the reservoir through the spout, and the axis of the container body is perpendicular to the vertical direction so that the spout is located below the handle. If the inclination angle is equal to or greater than a predetermined water stop angle, the steam flow path is closed by the weight body of the overturn stop valve.

As described above, if the steam flow path is closed by the weight of the overturn stop valve while the container body is inclined and the valve mechanism is closed in the sealed state, the storage section is sealed. When the hot water is stored in the storage part of the container body (for example, immediately after the heating by the heating mechanism is completed), the internal pressure in the storage part is caused by the steam generated from the hot water in the storage part. Will rise.
When the user opens the valve mechanism in a situation where the internal pressure in the storage portion has increased, there is a risk that hot hot water existing in the discharge flow path or the storage portion may protrude vigorously from the spout. There is a risk of unforeseen circumstances due to hot hot water protruding from the mouth.

  The present invention has been made in view of the above-described circumstances, and the main problem is that when a tipping water stop valve is provided in the steam channel, the container body is inclined to pour hot water from the spout. In this case, it is to provide a water heating container that can prevent an increase in the internal pressure of the reservoir and prevent hot water from protruding vigorously from the spout.

In order to achieve the above object, a water heating container according to the present invention is capable of closing a bottomed cylindrical container body having an opening on the upper side and having a storage part inside, and the upper opening of the container body in a sealed state. A lid, a handle provided in the container body, a heating mechanism for heating water in the reservoir, and the reservoir and the spout sealed by the lid communicate with each other, and the water in the reservoir is A pour-out passage through which the pour-out opening is made to flow; a valve mechanism provided in the pour-out passage and capable of closing the pour-out passage in a sealed state; and the storage sealed by the lid A water heating container having a steam flow path for communicating steam generated from the water in the storage section to the outside through the steam discharge port, the water heating container communicating with the portion and the steam discharge port. ,
The pouring spout is provided at a position on the outer peripheral side with respect to the central part of the container body and the lid body in a top view,
The steam flow path is movable along the guide wall according to the inclination angle of the axis of the container main body with respect to the vertical direction, and the steam flow is closed by closing the steam flow path by the movement. A falling water stop valve having a water stop member that can be switched to a water stop release state that opens the path is provided,
The steam channel is provided with a baffle portion that prevents the water stop member from entering the water stop state from the water stop release state on the spout side.

  According to the above characteristic configuration, basically, a bottomed cylindrical container body having an opening on the upper side and having a storage portion therein, a lid body capable of closing the upper opening of the container body in a sealed state, and the container body And a pour spout that communicates the water in the reservoir to the outside through the pour spout. Since it is provided at a position on the outer peripheral side with respect to the central part of the container main body and the lid body, the user holds the handle and tilts the container main body so that the spout side is located on the lower side for storage. The hot water in the section can be poured out through the opened valve mechanism, the pouring channel and the spout.

In addition, a container body with respect to the vertical direction is provided in a steam flow path that connects the storage part sealed by the lid and the steam discharge port and allows the steam generated from the water in the storage part to flow outside through the steam discharge port. The water stoppage that can be moved along the guide wall according to the inclination angle of the shaft center and can be switched between a waterstop state that closes the steam flow path and a water stop release state that opens the steam flow path by the movement. An overturn stop valve having a member is provided.
Thereby, according to the inclination angle of the axis of the container main body with respect to the vertical direction, the water stop member can be moved in a state of being guided along the guide wall, and switching between the water stop state and the water stop release state is stable. Can be done. Therefore, when the container body is tilted, the steam channel can be closed to prevent leakage of hot water from the steam channel, and when the container body is in the upright position, the steam channel is opened. In addition, the basic function of the overturning water stop valve that can discharge steam from the steam flow path can be stably exhibited.

In particular, a baffle portion is provided on the spout side of the steam channel to prevent the water stop member from entering the water stop state from the water stop release state.
As a result, the user grips the handle and tries to pour the hot water in the reservoir through the spout, and the axis of the container body is inclined with respect to the vertical direction so that the spout is located on the lower side. When the inclined posture is set, the baffle portion located on the spout side of the steam channel prevents the water stop member from entering the water stop state from the water stop release state, and the water stop member is in the water stop release state. The steam flow path is not closed.
In other words, even when the container body is inclined with the spout on the bottom, the state where the reservoir and the steam outlet (external (for example, about atmospheric pressure)) communicate with each other is maintained and is generated from the hot water in the reservoir. The discharged steam can be discharged to the outside through the steam discharge port. Therefore, when pouring hot water through the spout with the container body in an inclined posture with the spout on the lower side, it is possible to prevent the internal pressure in the reservoir from rising, even if the valve mechanism is opened. It is possible to prevent hot water from protruding from the spout of the outlet channel.

  In addition, since the baffle part is provided so as to be located on the spout side in the steam channel (the baffle part is not provided in the steam channel not located on the spout side), the container body falls over. In the case where the pouring spout is not positioned on the lower side and the axis of the container body is inclined with respect to the vertical direction, the water stop member is moved from the water stop release state along the guide wall. It becomes a water stop state and can close a steam channel.

  Therefore, in the case where a tip-over water valve is provided in the steam channel, while maintaining the basic function of the tip-over water valve, when the hot water is poured from the spout while the container body is inclined, The water heating container which can prevent a raise of internal pressure and can prevent hot water from protruding from a spout vigorously was provided.

According to a further characteristic configuration of the water heating container according to the present invention, the water stop member enters the water stop state when the inclination angle is equal to or greater than a predetermined water stop angle, and the inclination angle is the predetermined stop. If it is less than the angle for water, it is configured to be in the water stop release state,
In the case where the axis of the container body is inclined so that the spout side is positioned on the lower side, the inclination angle is within the baffle angle range not less than the predetermined water stop angle and not greater than the predetermined baffle angle. In some cases, the baffle portion is configured to prevent the water stop member from entering the water stop state from the water stop release state.

According to the above characteristic configuration, the water stop member enters a water stop state when the inclination angle is equal to or greater than the predetermined water stop angle, and the water stop member when the inclination angle is less than the predetermined water stop angle. It is comprised so that it may be in a cancellation | release state.
Therefore, when the inclination angle of the axis of the container main body with respect to the vertical direction is an inclination posture equal to or greater than a predetermined water stop angle, the steam flow path can be closed to prevent leakage of hot water from the steam flow path, The basic function of the overturn stop valve is that the steam flow path can be opened and steam can be discharged from the steam flow path when the inclination angle is less than the predetermined water stop angle. Can be stably exhibited. The predetermined water stop angle is set to an inclination angle before and after the axial center of the container main body is inclined with respect to the vertical direction and the hot water in the reservoir starts flowing through the steam channel. Can do.

In particular, when the axis of the container body is tilted so that the spout side is located on the lower side, the tilt angle is within a baffle angle range that is not less than a predetermined water stop angle and not greater than a predetermined baffle angle. In addition, the baffle portion is configured to prevent the water stop member from entering the water stop state from the water stop release state.
As a result, the user grips the handle and tries to pour the hot water in the reservoir through the spout, and the axis of the container body is inclined with respect to the vertical direction so that the spout is located on the lower side. If the inclined angle is equal to or greater than the predetermined water stop angle and is within the baffle angle range equal to or less than the predetermined baffle angle, the baffle located on the spout side of the steam channel The portion prevents the water stop member from changing from the water stop release state to the water stop state, the water stop member is maintained in the water stop release state, and the steam flow path is not closed.
That is, even if the container body is inclined with the spout on the lower side, the reservoir and the steam outlet (external (for example, about atmospheric pressure)) communicate with each other as long as the inclination angle is within the range of obstructions. Thus, the steam generated from the hot water in the reservoir can be discharged to the outside through the steam outlet. Therefore, when pouring hot water through the spout with the container body in an inclined posture with the spout on the lower side, it is possible to prevent the internal pressure in the reservoir from rising, even if the valve mechanism is opened. It is possible to prevent hot water from protruding from the spout of the outlet channel.

  Further, in this way, when the tilted position is such that the axis of the container body is tilted with respect to the vertical direction so that the spout side is located on the lower side, if the tilt angle exceeds a predetermined baffle angle (disturbance) The water stop member is not prevented from entering the water stop state from the water stop release state by the baffle part, and the water stop member may enter the water stop state and close the steam flow path. it can.

  In addition, when the container body falls down and the axis of the container body is inclined with respect to the vertical direction with the spout not positioned on the lower side, the inclination angle is set at a predetermined level. If the water stop angle is greater than or equal to the water stop angle (including the baffle angle range greater than or equal to the predetermined water stop angle and less than or equal to the predetermined baffle angle), the water stop member changes from the water stop release state to the water stop state along the guide wall Thus, the steam flow path can be closed.

  A further characteristic configuration of the water heating container according to the present invention is that the baffle portion is provided on a specific induction wall located on the spout side among the induction walls arranged in the steam flow path. is there.

According to the above characteristic configuration, the baffle portion is provided on the specific guide wall located on the spout side among the guide walls arranged in the steam flow path (the guide wall not located on the spout side has a baffle). Therefore, the baffle portion can be efficiently provided using a guide wall that guides and guides the movement of the water stop member.
In addition, when the inclined position is such that the axis of the container body is inclined with respect to the vertical direction so that the spout is located on the lower side, the guide is guided to the specific guide wall located on the spout side of the guide wall. The water stop member is prevented from entering the water stop state from the water stop release state by the baffle provided on the specific guide wall, the water stop member is maintained in the water stop release state, and the steam flow path is closed. Will not be.
Therefore, by using the guide wall that guides and guides the water-stopping member, the baffle is efficiently provided, and when pouring hot water through the spout as an inclined posture in a state where the spout is on the lower side, It is possible to prevent the internal pressure in the reservoir from rising, and even if the valve mechanism is opened, hot water can be prevented from protruding from the spout of the pouring channel.

A further characteristic configuration of the water heating container according to the present invention is that the overturn stop valve has a box-shaped storage chamber for storing the water stop member, and an upstream steam hole formed in a bottom wall portion of the storage chamber. And a downstream steam hole formed in the ceiling wall portion of the storage chamber, and the guide wall disposed in the storage chamber,
The water stop member is configured so as to be in the water stop state in which the steam flow path is closed by moving along the guide wall in the housing chamber and closing the downstream steam hole. is there.

According to the above characteristic configuration, the overturn stop valve is formed in the box-shaped storage chamber that stores the water stop member, the upstream steam hole formed in the bottom wall portion of the storage chamber, and the ceiling wall portion of the storage chamber Since the downstream steam hole and the guide wall disposed in the storage chamber are provided, when the inclined posture is obtained by inclining the axis of the container body with respect to the vertical direction, the water stop member is disposed in the storage chamber. The state of moving from the state in contact with the bottom wall portion of the storage chamber (water stop release state) while being guided along the guide wall to close the downstream side steam hole (steam channel) formed in the ceiling wall portion It can comprise so that it may switch to (water stop state).
Thereby, the specific structure which exhibits the said basic function as a fall stop water valve was able to be obtained.

According to a further characteristic configuration of the water heating container according to the present invention, the overturn stop water valve includes a first overturn stop water valve and a second overturn stop water valve,
The first overturn stop valve includes a first storage chamber as the storage chamber, a first upstream steam hole as the upstream steam hole, and a first downstream steam hole as the downstream steam hole, A first guide wall as the guide wall; and a first water stop member as the water stop member movable along the first guide wall;
The second overturning water valve includes a second storage chamber as the storage chamber, a second upstream steam hole as the upstream steam hole, a second downstream steam hole as the downstream steam hole, A second guide wall as the guide wall; and a second water stop member as the water stop member movable along the second guide wall;
The opening area of the second downstream steam hole is formed to be smaller than the opening area of the first downstream steam hole,
The baffle is provided on the second guide wall.

According to the above characteristic configuration, each of the first fall stop water valve and the second fall stop water valve constituting the fall stop water valve includes the storage chamber, the upstream steam hole, the downstream steam hole, the guide wall, and the water stop member. And the opening area of the second downstream steam hole of the second tipping water stop valve is formed to be smaller than the opening area of the first downstream steam hole of the first tipping stop water valve, and the baffle part Is provided on the second guide wall of the second tipping water stop valve.
As a result, the user grips the handle and tries to pour the hot water in the reservoir through the spout, and the axis of the container body is inclined with respect to the vertical direction so that the spout is located on the lower side. In the inclined posture, the first water stop member of the first fall stop water valve moves along the first guide wall, and the first downstream of the first fall stop water valve having a relatively large opening area. The movement of the second water stop member of the second falling water stop valve along the second guide wall is an obstruction provided on the second guide wall while the side steam hole is closed (the water stop state is set). Therefore, the second downstream side steam hole of the second tipping water stop valve having a relatively small opening area is not closed (set to a water stop releasing state).
In other words, when the container body is inclined so that the spout is located on the lower side, the first downstream steam hole is closed, so that the hot water in the reservoir is vaporized from the first downstream steam hole having a large opening area. Opening the second downstream steam hole while preventing leakage to the outside through the steam discharge port of the flow path allows the steam in the reservoir to flow from the second downstream steam hole having a small opening area to the steam flow path. It can be discharged outside through the steam outlet.
Therefore, when the container body is inclined so that the spout is located on the lower side, the first falling water stop valve prevents the hot water in the reservoir from leaking from the steam flow path, It is possible to prevent the rising and hot water from protruding vigorously from the spout.

  A further characteristic configuration of the water heating container according to the present invention is that the second upstream steam hole is on the side opposite to the spout side, and is a second bottom as the bottom wall portion of the second storage chamber. It exists in the point provided in the lower end of a wall part.

  According to the above characteristic configuration, the second upstream steam hole is provided on the opposite side of the spout side and at the lower end of the second bottom wall portion of the second storage chamber. When gripping and pouring the hot water in the storage part to the outside through the spout, when the tilted posture in which the axis of the container body is inclined with respect to the vertical direction so that the spout is located on the lower side, The second upstream steam hole is positioned above the spout, and the second upstream steam hole is configured so as not to be submerged as much as possible, and the second upstream steam hole of the storage unit and the second storage chamber and Communication with the steam flow path (steam discharge port) via the second downstream steam hole can be maintained as much as possible. That is, when pouring hot water from the pouring spout, the steam in the storage section can be passed through the steam passage (steam discharge port) via the second upstream steam hole and the second downstream steam hole. Can do.

  A further characteristic configuration of the water heating container according to the present invention is that the pouring spout is provided on the front side in the front-rear direction of the container main body and the handle is provided on the rear side opposite to the pouring spout in a top view. It is in the point.

According to the above-described characteristic configuration, the top is provided with a spout on the front side in the front-rear direction of the container body, and the handle is provided on the rear side opposite to the spout. In the inclined posture, the hot water in the reservoir is poured out through the spout, and the axis of the container body is inclined with respect to the vertical direction so that the spout is located below the handle. And usability can be improved.
In addition, when the container body falls, the container body has the axis of the container body parallel to the horizontal direction, and the front-rear direction connecting the spout and the handle is substantially parallel to the horizontal direction. In other words, when the axis of the container body is inclined with respect to the vertical direction, the spout is not positioned on the lower side, so that the water stop member is stopped along the guide wall without being obstructed by the baffle. From the water release state to the water stop state, the steam flow path can be closed.
That is, even if it is a structure provided with a baffle part, it can prevent that hot water leaks outside via a steam flow path at the time of the fall of a container main body.

A further characteristic configuration of the water heating container according to the present invention is that the overturn stop valve has a box-shaped storage chamber for storing the water stop member, and an upstream steam hole formed in a bottom wall portion of the storage chamber. And a downstream steam hole formed in the ceiling wall portion of the storage chamber, and the guide wall disposed in the storage chamber,
The water stop member is configured to move in the accommodating chamber along the guide wall and close the downstream steam hole to be in the water stop state for closing the steam flow path,
In the accommodation chamber, the guide wall is configured to surround the water blocking member from a side portion excluding the ceiling wall portion and the bottom wall portion of the accommodation chamber.

According to the above characteristic configuration, the overturn stop valve is formed in the box-shaped storage chamber that stores the water stop member, the upstream steam hole formed in the bottom wall portion of the storage chamber, and the ceiling wall portion of the storage chamber Since the downstream steam hole and the guide wall disposed in the storage chamber are provided, when the inclined posture is obtained by inclining the axis of the container body with respect to the vertical direction, the water stop member is disposed in the storage chamber. The state of moving from the state in contact with the bottom wall portion of the storage chamber (water stop release state) while being guided along the guide wall to close the downstream side steam hole (steam channel) formed in the ceiling wall portion It can comprise so that it may switch to (water stop state).
In addition, since the guide wall surrounds the water stop member from the side portion excluding the ceiling wall portion and the bottom wall portion of the storage chamber in the storage chamber, the guide wall stops according to the inclination angle of the axis of the container body with respect to the vertical direction. When moving the water member while being guided along the guide wall, it is possible to guide the weight of the water stop member due to the inclination of the container body while supporting it from the side by the guide wall. Movement can be realized.

The water heating container according to the present invention is further characterized in that a plurality of plate-like projecting portions projecting from the ceiling wall portion to the bottom wall portion side of the storage chamber surround the water stop member from the side portion. Arranged in a ring,
The guide wall is configured by a radially inner side surface of the plurality of plate-like protrusions arranged in an annular shape,
The said baffle part exists in the point which is a step provided in the specific radial direction inner side surface located in the said spout side among these radial inner side surfaces.

According to the above characteristic configuration, the plurality of plate-like projecting portions projecting from the ceiling wall portion of the storage chamber toward the bottom wall portion surround the water stop member from the side portion excluding the ceiling wall portion and the bottom wall portion of the storage chamber. Since the guide wall is constituted by the radially inner side surfaces of the plurality of plate-like protrusions arranged in an annular shape, the guide wall is stopped according to the inclination angle of the axis of the container body with respect to the vertical direction. When the water member is moved along the guide wall, its own weight due to the inclination of the water stop member due to the inclination of the container body is caused to the entire circumference of the water stop member by the radially inner side surfaces of the plurality of plate-like protrusions. It can be guided while being supported from the side where it extends, and more accurate and reliable movement can be realized. Particularly, the baffle is located in the specific radial direction located on the spout side among the plurality of radial inner surfaces. Since the step is provided on the side, the user holds the handle and stores it. When the internal water is poured into the outside through the spout and the container body is tilted with respect to the vertical direction so that the spout is located on the lower side, By hooking on a step provided on the specific radial inner surface located on the spout side among the plurality of radial inner surfaces, the water stopping member is prevented from entering the water stopping state, and the water stopping member is stopped. The water release state is maintained and the steam flow path is not closed. Note that the baffle portion only needs to be formed on the inner surface of the specific radial direction, and therefore can be formed very simply and easily.

A further characteristic configuration of the water heating container according to the present invention is provided with a plurality of the inner surfaces in the specific radial direction,
The spout side specific portion as the step portion provided on the spout side specific radial direction inner side surface closest to the spout side among the plurality of specific radial direction inner surfaces is the spout side specific diameter. It is in the point comprised so that a bigger level | step difference may be provided than the adjacent step part as said step part formed in the adjacent specific radial direction inner side surface adjacent to a direction inner side surface.

According to the above characteristic configuration, the spout side step provided on the spout side specific radial direction inner side surface closest to the spout side among the plurality of specific radial direction inner surfaces is the spout side specific radial direction. Since it is configured to have a larger step than the adjacent step formed on the adjacent specific radial inner surface adjacent to the inner surface, the axis of the container body is vertically oriented so that the spout is located on the lower side. When the inclined posture is inclined with respect to the water-stopping member, the water-stopping member is reliably prevented from moving in the direction along the inner side surface in the specific radial direction by being reliably caught by the spout side stepped portion having a large step. At the same time, the movement in the direction along the inner surface of the specific radial direction is also prevented by being caught by an adjacent step portion having a small step, and the water stop state is prevented from entering the water stop state.
On the other hand, if the pouring spout is not positioned on the lower side and it is tilted (when the container body falls, etc.), the user may not try to pour hot water in the reservoir through the spout Therefore, it is necessary to switch the water stop member from the water stop release state to the water stop state at an early stage. Here, if the pouring spout is in an inclined position without being positioned on the lower side, the water-stopping member is adjacent to the spout-side specific radial inner side surface without being caught by the spout-side stepped portion. The radial inner surface and the radial inner surface of the guide wall may come into contact with each other. In this state, the water stop member is caught by the adjacent step portion of the adjacent specific radial inner surface, and the water stop is released. May be prevented from entering a water-stopping state.
Even in such a case, since the adjacent stepped portion is configured by a relatively small step, the water-stopping member caught on the adjacent stepped portion gets over the adjacent stepped portion at an early stage and switches to the water-stopping state as soon as possible. The steam flow path can be closed early.

  The further characteristic structure of the water heating container which concerns on this invention exists in the point by which the said water stop member is comprised by the spherical body.

According to the above characteristic configuration, since the water stop member is constituted by a sphere, when the inclined posture is obtained by inclining the axis of the container body with respect to the vertical direction, the water stop member is formed according to the inclination angle of the container body. It moves quickly along the guide wall, and the steam flow path can be closed quickly.
Further, the weight can be reduced as compared with the shape of a cube, a rectangular parallelepiped, a truncated cone, or the like.

Further, a sealing material 33 is provided on the outer peripheral side of the positioning rib, and the space between the outer peripheral edge portion of the overturn stop water valve G and the lower surface of the lower side wall member 34 is sealed.

The upper side wall member 35 is a plate-like member that is long in the left-right direction. A projecting outer wall 35a and a projecting inner wall 35b projecting downward are formed. Accordingly, a space surrounding in the three directions (front side, left and right sides) other than the rear side (opening 35c) is formed inside the protruding outer wall 35a and the protruding inner wall 35b. The opening 35c is formed so as to be positioned at the center in the left-right direction in the upper wall member 35.
Between the protruding outer wall 35a and the protruding inner wall 35b of the upper side wall member 35, it is possible to fit in a fitting groove (not shown) of the protruding outer wall 34a and the protruding inner wall 34b of the lower side wall member 34 at the center in the thickness direction.

  At the place where the lower wall member 34 and the upper wall member 35 are fitted, the lower wall member 34 and the upper wall member 35 are sealed. Further, an opening 38A is formed by combining the opening 34c of the lower wall member 34 and the opening 35c of the upper wall member 35. A packing member 39 is attached to the cylindrical portion 38 forming the opening 38A so as to seal the opening 38A. When the steam flow path forming member E assembled in this way is attached to the upper surface of the lid body 19 of the lid body 5 and the lid body 5 is attached to the upper opening 4 of the body body 2, the steam flow path formation member The above-described bulging space 30 is formed inside E.

Next, the detection steam channel 14 will be described.
As shown in FIG. 3, the detection steam channel 14 is provided outside the inner container 1 so as to extend across the detection-side steam inlet 2 h and the steam detection unit C provided at the bottom of the inner container 1. Yes.
The detection steam inlet 2h is formed in a rear portion formed so as to be higher in the upper portion of the inner container 1 than the front portion and to rise to a state adjacent to the rear side of the bulging space 30. It is formed and connected to the bulging space 30 in communication.

  Specifically, an elongated detection steam channel forming body 46 having a substantially U-shaped cross section in a direction orthogonal to the longitudinal direction covers the detection-side steam inlet 2h from the rear side, In a state of communicating with the detection unit C, the opening is provided along the vertical direction on the rear side of the outer surface of the inner container 1, and the outer surface of the inner container 1 and the detection steam flow path forming body 46 are provided. In between, the detection steam flow path 14 is formed. The detection steam flow path forming body 46 is formed by resin molding so that the cross-sectional shape is substantially U-shaped and the longitudinal direction is a shape along the vertical direction on the outer surface of the inner container 1. The inner container 1 can be provided in close contact with the outer surface.

  Next, the state at the time of heating the hot water in the inner container 1 using the electric kettle comprised as mentioned above and pouring the heated hot water from the spout 6 is demonstrated.

When the user places the main body 2 on the power supply plate S and presses the button portion 16a of the push button 16 to heat the hot water in the inner container 1, electric heat is supplied from the power feeding mechanism Ps via the power receiving mechanism Pr. Electric power is supplied to the heater 3, and hot water in the inner container 1 is heated by the electric heater 3.
When steam is generated from the hot water in the inner container 1 with the heating, the steam rises sequentially, and the bulging space 30 is reached via the steam inlet hole 28, the accommodation chamber 37, and the steam inlet 29 of the overturn stop valve G. Will be introduced inside. A part of the steam introduced into the bulging space 30 flows into the detection steam flow path 14 through the cylindrical portion 38 of the steam flow path forming member E, the opening 38A, and the detection side steam introduction port 2h. The other portion of the steam is led from the bulging space 30 to the downstream side of the valve mechanism 10 through the outlet 31 and the through-hole 19B, and is condensed. Steam that is not discharged is discharged from the spout 6.

  Thereafter, when the heating of the hot water in the inner container 1 is finished (in some cases, the heating may be in progress), when the heated hot water is poured out through the spout 6, the user must handle the handle 7. By operating the operating portion 13a of the spout opening / closing member 13 while gripping and tilting the main body 2 so that the spout 6 side is lower than the handle 7 side, the hot water in the inner container 1 is discharged from the spout 6. Can flow outside.

  Here, in the electric kettle configured as described above, when the heated hot water is poured out through the spout 6 as shown in FIGS. Even when the main body 2 is maintained in an inclined posture so that the spout 6 side is positioned below the handle 7 side without operating the operation portion 13a of the member 13, the contents will be described as described below. The internal pressure of the vessel 1 does not increase.

Specifically, as shown in FIGS. 7 and 8, the user grasps the handle 7 and tries to pour out the hot water in the inner container 1 to the outside through the spout 6. In the state which does not open 24, it is set as the inclination attitude | position which inclined the axial center X of the main body 2 with respect to the perpendicular direction so that the spout 6 may be located below, and the inclination angle is more than a predetermined water stop angle When the angle is within the baffle angle range below the baffle angle, as shown in FIG. 8, the first weight body 37a of the first overturning water valve extends along the radially inner side surface 34f of the plate-like protrusion 34A. It moves and closes the first steam inlet port 29A (see FIG. 4) having a relatively large opening area (set to a water stop state), whereas the second weight body 37b of the second tipping water stop valve is Although it moves along the specific radial inner side surface 34g of the specific plate-like protruding portion 34B, the specific radial direction inner side surface 34g The movement is prevented by being caught by the stepped portion 34x, and the water stop state is prevented from entering the water stop state, and the second weight body 37b is maintained in the water stop release state, and is relatively open. The second steam introduction port 29B having a small area is configured not to be closed (set to a water stop release state). In this embodiment, the inclination angle of the axis X of the main body 2 with respect to the vertical direction Y is set to 90 degrees, the predetermined water stop angle is set to 90 degrees, the predetermined baffle angle is set to 110 degrees, Since the baffle angle range is set to 90 degrees or more and 110 degrees or less, in FIG. 7 and FIG. 8, the inclination angle of the main body 2 is a predetermined water stop angle (within the baffle angle range).
That is, when the main body 2 is inclined such that the spout 6 is positioned on the lower side, if the inclination angle is within the baffle angle range, the first steam inlet hole 29A is closed. Thus, while preventing hot water in the inner container 1 from leaking outside through the first steam inlet port 29A having a large opening area through the outlet steam channel 11 and the outlet 6 of the outlet channel 9, By opening the second steam inlet 29B, the steam in the inner container 1 is externally supplied from the second steam inlet 29B having a small opening area through the outlet steam passage 11 and the outlet 6 of the outlet passage 9. Can be discharged.

  At this time, the spout side specific portion 34y provided on the spout side specific radial direction inner side surface 34h closest to the spout side among the plurality of specific radial direction inner surfaces 34f has a spout side specific diameter. The main body 2 is configured to have a step larger than the adjacent step portion 34z formed on the adjacent specific radial inner surface 34i adjacent to the direction inner side surface 34h, so that the spout 6 is positioned on the lower side. If the tilt angle is in the range of the baffle angle, the second weight body 37b is formed on the spout side step portion 34y having a large step. The movement along the specific radial inner side surface 34f is reliably prevented by being caught reliably, and the movement along the specific radial inner side surface 34y is also prevented by being caught by the adjacent step portion 34z having a small step, Still water solution Become a water stop state is prevented from state.

  Further, since the second steam inflow hole 28b is provided on the opposite side to the spout 6 side and at the lower end of the second bottom wall portion 27e of the second storage chamber 36B, the spout 6 is on the lower side. The second steam inlet hole 28b is formed from the spout 6 when the tilt angle is in the baffle angle range when the axis X of the main body 2 is tilted with respect to the vertical direction Y so as to be positioned. The second steam inlet hole 28b is configured so as not to be submerged as much as possible, through the inner container 1 and the second steam inlet hole 28b and the second steam inlet port 29B of the second storage chamber 36B. It is possible to maintain the communication with the outlet steam channel 11 (the spout 6) as much as possible.

  Therefore, while preventing the hot water in the inner container 1 from leaking from the outlet steam channel 11 by the first overturn stop valve G1, the second overturn water valve G2 increases the internal pressure in the inner container 1 and the hot water. Can be prevented from protruding vigorously from the spout 6.

Also, when the tilted posture is such that the axis X of the main body 2 is tilted with respect to the vertical direction Y so that the spout 6 side is located on the lower side, as shown in FIGS. If the inclination angle exceeds a predetermined baffle angle (out of the baffle angle range), the first weight body 37a can maintain the water-stopping state and close the outlet steam channel 11 in addition to the first baffle angle range. The double weight body 37b goes over the step portion 34x, changes from the water stop release state to the water stop state, and can close the outlet steam channel 11. 9 and 10 show a state where the inclination angle of the axis X of the main body 2 with respect to the vertical direction Y exceeds 110 degrees.
Therefore, when the tip-off water stop valve G is provided in the outlet steam channel 11, the main body 2 is tilted and hot water is poured out from the spout 6 while maintaining the basic function of the tip-off water stop valve G. In doing so, an increase in the internal pressure of the inner container 1 can be prevented, and hot water can be prevented from protruding vigorously from the spout 6.

  On the other hand, the step portion 34x is provided on the specific radial inner side surface 34g located on the spout 6 side of the radial inner side surface 34f of the plate-like protruding portion 34A protruding downward from the lower surface of the second ceiling wall portion 34e. (The step 34x is not provided on the radially inner side surface 34f that is not located on the side of the spout 6), so that the main body 2 falls down and the spout 6 is not located on the lower side. When the axis X of the main body 2 is inclined with respect to the vertical direction Y, the inclination angle is equal to or greater than a water stop angle (a predetermined water stop angle or more and a predetermined baffle angle or less). The weights 37 (the first weight body 37a and the second weight body 37b) stop from the water stop release state along the radially inner side surface 34f where the step portion 34x does not exist. In the water state, the outlet steam channel 11 can be closed.

On the other hand, when the tilt angle is within the range for the baffle but the pouring spout 6 is not positioned on the lower side and the tilting posture is assumed (when the main body 2 falls down, etc.), the user 6, there is a high possibility that the hot water in the inner container 1 is not poured out, so it is necessary to switch the second weight body 37b from the water stop release state to the water stop state at an early stage. When the pouring spout 6 is in an inclined position without being positioned below, the second weight body 37b is formed on the spout-side specific radial inner surface 34h of the spout-side specific plate-like protrusion 34C. The spout-side stepped portion 34y may come into contact with the adjacent specific radial inner side surface 34i of the adjacent specific plate-like protrusion 34D and the radial inner side surface 34f of the plate-like protrusion 34A without being caught. In this state, the second weight body 37b may be caught by the adjacent stepped portion 34z of the adjacent specific radial direction inner side surface 34i, and the water stoppage state may be prevented from entering the waterstop release state.
Even in such a case, the adjacent stepped portion 34z is constituted by a relatively small step, so the second weight body 37b caught on the adjacent stepped portion 34z gets over the adjacent stepped portion 34 at an early stage and stops as soon as possible. It is possible to switch to the water state and to close the outlet steam channel 11 at an early stage.

For example, if the weight body 37 (an example of a water stop member) can be appropriately guided to a water stop state and a water stop release state according to the inclination angle of the axis X of the main body 2 with respect to the vertical direction Y, guidance is provided. The wall can be constituted by a side wall constituting the accommodation chamber 36, and the guide wall can be constituted by a plate-like / wall-like member disposed in the accommodation chamber 36.

(B) In the above-described embodiment, the specific plate-like projecting portion 34B located on the spout 6 side among the plurality of plate-like projecting portions 34A that project the baffle portion downward from the lower surface of the lower side wall member 34. Although it is configured by the step 34x of the side surface 34g, it is positioned on the spout 6 side of the outlet steam channel 11 and can prevent the weight body 37 from entering the water stop state from the water stop release state. As long as there is any other configuration, for example, a configuration may be adopted in which a friction holding portion that increases friction with the weight body 37 is provided on the specific plate-like projecting portion 34B.
The friction holding portion may have a surface processing that forms fine irregularities (roughens the surface) so as to increase the friction coefficient of a part of the surface of the specific radial inner side surface 34g.
Specifically, in the vertical direction, fine irregularities are formed over the entire surface from the lower end to the upper end of the surface of the specific radial inner side surface 34g, or fine irregularities are formed in the region from the lower end to the upper end. The friction holding part is formed by forming fine irregularities in the region from the middle between the lower end and the upper end to the upper end, or forming fine irregularities in the middle between the lower end and the upper end. can do.
Moreover, as this friction holding | maintenance part, the structure etc. which mounted | worn with the rubber product etc. with a high friction coefficient in a part of specific plate-shaped protrusion part 34B can be illustrated.

When the axis 34 of the main body 2 is inclined so that the side of the spout 6 is positioned on the lower side, the inclination angle is equal to or greater than a predetermined water stop angle and a predetermined obstruction. The baffle portion is configured to prevent the second weight body 37b from entering the water stop state from the water stop release state when the angle is within the angle range for the baffle below the angle. However, when the axis X of the main body 2 is inclined so that the spout 6 side is located on the lower side, the baffle portion always keeps the weight body 37 in the water stop released state. It is also possible to adopt a configuration that always prevents it from happening.

(D) In the above embodiment, the inclination angle of the axis X of the main body 2 with respect to the vertical direction Y is set to 90 degrees, the predetermined water stop angle is set to 90 degrees, and the predetermined baffle angle is set to 110 degrees. The example in which the baffle angle range is set to 90 degrees or more and 110 degrees or less has been described. However, the predetermined water stop angle is such that the axis X of the container body 4 is substantially parallel to the horizontal direction (the axis X of the axis X). A predetermined angle at which the first weight body 37a closes the first steam inlet port 29A and the second cone 37b closes the second steam inlet port 29B in a fall posture with an inclination angle of about 90 degrees). An arbitrary angle within a range (for example, within a range of about 90 ° ± 10 °) can be set. Further, the predetermined baffle angle can be set to an arbitrary angle within a predetermined angle range (for example, a range of about 110 ° ± 10 °) as an angle larger than the predetermined water stop angle. . In this case, when a predetermined baffle angle is exceeded, the cone 37 maintained in the water stop release state by the baffle portion can be configured to be switched to the water stop state. In this way, when it is not necessary to switch the cone 37 maintained in the water stop released state by the baffle portion to the water stop state, the predetermined baffle angle is set within the predetermined angle range ( For example, the angle can be larger than an arbitrary angle within a range of about 110 degrees ± 10 degrees.
