Description

  The present invention relates to a lid for a water heater, and more specifically, a disc-shaped lid that is plug-fitted so as to be detachable in a substantially axial direction in a recessed portion at the upper end of a water heater that is heated by a heater and closes the water heater area from above. The present invention relates to a lid for a water heater having a main body, and having an attachment / detachment portion that is operated or grasped from above on the inner side of the upper surface of the main body to be attached to and detached from the body.

The lid attachment / detachment structure having an attachment / detachment portion that is operated or gripped from the upper side inside the upper surface of the main body and is attached to / detached from the body is provided with a protrusion rising from the circular recess on the diameter line of the circular recess. For example, it has been seen for a long time on the lids of various containers, and has an advantage that it can be easily attached and detached with a simple structure. There is also known a lid that opens and closes and removes the lid by providing a catch portion that can be hooked by a finger from the top of the lid using the recess (see, for example, Patent Document 1).

  However, the lid as described above includes a simple structure that has been seen for a long time, the lid body described in Patent Document 2, and the lid body from which the operation portion of the opening operation restricting member described in Patent Document 1 protrudes. The upper surface is relatively flat and easy to stabilize in the mounted state, and the removed lid is in a supine state because it is described in Patent Document 1 and is not wet with steam like the inner surface of the lid. In other words, it is often placed with the inner side facing up. In addition to wetting the mounting portion when placed on the inner surface, this seems to be a major cause of fear that the sanitary surface of the inner surface is damaged.

  In such a mounting state of the lid body, the attaching / detaching portions of these lid bodies are located on the placement surface side and are hidden by the lid body, so that the attaching / detaching portion cannot be used to lift the placed lid body, If the diameter is large, both hands can be applied from both sides, and if the diameter is small, one hand can be gripped by placing fingers from the inner surface outward.

  However, in the former case, if both hands are held, there is an inconvenience that both hands are blocked, and since the grip extends to the inner surface side, the inner surface is exposed to steam during use of the water heater or immediately after use, and the temperature is high. There is something that makes me feel a little thicker. In the latter case, the inner surface which may be hot is directly touched, which is dangerous and unsanitary.

  The object of the present invention is to solve such problems, and can be placed in an upright position where the upper surface having an attaching / detaching portion for attaching / detaching the lid by operation or gripping is not blocked. An object of the present invention is to provide a lid for a water heater in which a series of operations of lifting and mounting can be easily performed by gripping the attaching / detaching portion.

In order to solve the above-mentioned problems, the lid of the water heater according to the present invention is plug-fitted so as to be detachable in the axial direction in the recessed portion at the upper end of the water heater which is heated by the heater, and closes the water heater area from above. A water heater lid having a disk-shaped main body, and having a detachable part that is attached to and detached from the main body by operating or grasping the main body from the upper side inside the upper surface of the main body. The unit is located on substantially the same plane including at least one of a plane part, a line part, and a dot part, and the main body is prevented from falling to the upper surface side and the inner surface side and from rolling to the left and right. It is characterized in that a stationary part that can be stationary is formed.

  In such a configuration, since the main body is plug-fitted into the body of the water heater, the thickness between the inner surface and the upper surface can be increased, so it occurs due to the pouring path and water heater for pouring the content liquid to the outside. In addition to the steam passage that allows the steam to escape to the outside, there is an advantage that it is easy to incorporate a detachable part that attaches and detaches the lid to the recessed part of the vessel with or without locking the lid to the vessel side, The temperature rise on the upper surface side including the operation portion of the attaching / detaching portion can be largely suppressed with respect to the inner surface side directly exposed to the steam. Therefore, the stationary part for placing the main body in the standing posture can take a rolling prevention width or interval that can prevent rolling in the direction in which the lid rolls to the left and right more than necessary, and falls to the inner surface side and the upper surface side from the standing posture. The top surface of the lid including the operation side of the attaching / detaching part that is stably placed in an upright position so that the main body can be stably placed in an upright position and can be operated or gripped. Can be left open together with the inner surface without being touched by others.

  In addition to the above, the stationary portion does not need to be a flat surface, and at least three stationary points satisfy a rolling prevention width or interval, a fall prevention width or interval, and a plane in which the main body is stabilized in a standing posture. The upper surface on the operation side of the attaching / detaching portion can be opened in an obliquely upward direction as long as the flat surface stabilizes the main body in a posture inclined forward toward the inner surface.

  In the above, the stationary part may be provided from substantially the upper surface side to the substantially inner surface side of the main body.

  In such a configuration, in addition to the above, it is possible to further ensure a large fall prevention width or interval of the stationary portion by utilizing almost the entire thickness of the main body.

Two point-like portions in the left-right direction satisfying the circumferentially preventing rolling prevention interval that can be prevented, and the upper side of the main body at the center point of the rolling prevention width or rolling prevention interval at the circular side end on the inner surface side of the main body And one point-like portion which is a portion facing the axial direction of the main body while satisfying a fall prevention interval capable of preventing the fall to the inner surface side.

  In such a configuration, in addition to the above, the inner surface of the main body can be obtained simply by providing a line shape or one point-like portion satisfying a width or interval to prevent rolling to the left and right on the upper surface side of the main body in a circular shape. It is possible to realize a stationary part that places the main body in a standing posture with one point-like part formed by a part in the circumferential direction of the circular side end on the side.

  In the above, the detachable portion further includes a pair of engagements that engage with a pair of left and right engaging recesses on the inner surface of the recessed portion by a biasing force at the plug fitting position of the main body to lock the main body at the plug fitting position. And a pair of left and right operation portions that are separated from each other between a separation position and an approach position approaching from the separation position in conjunction with the locking and unlocking operations by the engagement member. The part is positioned facing the operation window between the two positions so that the gripping operation is performed with the reaction force of the bias from the separated position to the approach position through the operation window formed on the upper surface of the main body, It can be characterized in that it is used for unlocking, attaching / detaching, and carrying.

In such a configuration, in addition to the above, when the main body is plugged into the recessed portion of the container, the left and right engaging members are elastically engaged with the engaging recesses on the left and right of the inner surface of the recessed portion of the container by the biasing force. In combination, the main body is locked in the closed state. In this state, when the two left and right operation portions facing the operation window on the upper surface of the main body are gripped from the separation position to the approach position through the operation window against the reaction force due to the urging force, the engaging member is interlocked therewith. Since the latch is released from the engaging recess, the lid can be removed from the recessed portion while the two operating portions are gripped, and can be carried as it is to place the stationary portion at a desired position and the lid. You can leave your body upright.

  In the above, a seal member is further provided that is attached to the inner surface side end of the main body, presses against the water heater region mouth portion of the body and seals between them, and this seal member is attached to the inner surface side end portion of the main body. The base lip has a sealing lip with a bent cross section extending from the inside of the outer peripheral portion of the inner surface of the main body to the outer peripheral portion while extending from the inner side to the inner diameter and then further to the inner side. A seal lip can be used to seal the space between the boiling area of the container.

  In such a configuration, in addition to the above, the seal member attached to the inner surface side end of the main body is closely connected to the water heater opening of the container at the innermost part plugged into the recessed part of the container. It can be pressed and sealed to prevent water leakage from the inner surface of the main body to the upper surface side. Further, the sealing member has a cross-sectionally bent shape and the seal lip has a groove that extends inward from the inner periphery of the inner surface of the main body and has a bent portion on the outer peripheral side. None, when the lid is placed in a standing posture, it can receive and store the dew condensation water that runs down the inner surface.

  Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be used alone or in combination in various combinations as much as possible.

  According to the lid of the water heater of the present invention, the main body is plug-fitted and has a large thickness, a pouring path that is easy to stop water in the event of a fall, a steam passage that prevents abnormal pressure rise, and a body side that prevents inadvertent dropping There is a built-in attachment / detachment part that attaches / detaches the lid body to / from the recessed part of the body without or with locking, and further raises the temperature on the upper surface side including the operation part of the attachment / detachment part. In a place that is greatly reduced and convenient for ensuring safe use, the main body is stably placed in a small plane space in a standing position with a stationary part that takes advantage of the large left and right dimensions of the main body and a relatively large thickness. The upper surface of the lid including the operation side of the attaching / detaching part operated or gripped from the upper surface side of the main body is left open with the inner surface often wetted at the highest temperature and cannot be closed without being touched elsewhere. The hygienic surface where the inner surface is placed and the problem of wetting are solved In addition, a series of handling such as removing, placing, lifting from the loaded state, and remounting the lid is easy and safe only on the outer surface without operating or holding the detachable part and touching the inner surface of the lid. Yes. Further, the mounting in the standing posture has an advantage that the temperature can be lowered quickly to a temperature at which there is no problem even if it is touched by promoting heat radiation to the surroundings.

  In addition to the above, the stationary portion does not need to be a flat surface, and at least three stationary points satisfy a rolling prevention width or interval, a fall prevention width or interval, and a plane in which the main body is stabilized in a standing posture. The upper surface on the operation side of the attachment / detachment portion is opened in an obliquely upward direction, and the attachment / detachment portion is operated or gripped by this plane, which stabilizes the main body in a posture inclined forward toward the inner surface side. The lid can be easily placed and lifted from the stationary state. In addition, as the stationary point of the stationary part is closer to three or more points, stable stationary can be achieved without the influence of surface distortion.

  In addition to the above, the stationary portion provided substantially on the upper surface side from the inner surface of the main body can ensure a large fall prevention width or interval using almost the entire area of the thickness of the main body, and it is easy to prevent the fall. .

In addition to the above, a circular end on the inner surface side of the main body can be obtained simply by providing a line shape or one point-like portion satisfying a width or interval to prevent rolling to the left and right on the upper surface side of the main body, which is a circular shape. It is possible to realize a stationary part that places the main body in a standing posture with one point-like part formed by a part in the circumferential direction with almost no change in the circular normal form.

  In addition to the above, when the main body is plugged into the recessed portion of the container, the left and right engaging members are elastically engaged with the engaging recesses on the left and right of the inner surface of the recessed portion by the biasing force to close the main body. It is locked in the state, and it becomes easy to attach to the drop-off prevention state. In this state, when the two left and right operation portions facing the operation window on the upper surface of the main body are gripped against the reaction force caused by the urging force, the engaging member comes out of the engaging recess and interlocks with it. Can be easily released and the lid can be removed from the recessed portion while the two operating parts are in the gripping operation state, and can be carried as it is to place the stationary part at a desired position and leave the lid in an upright position. .

  In addition to the above, the seal member attached to the inner surface side end of the main body is tightly pressed and sealed to the hot water boiling region mouth of the container at the innermost part plugged into the recessed part of the container, It is possible to prevent water leakage from the inner surface of the main body to the upper surface side, and to prevent the outer periphery other than the inner surface and the inner surface of the seal member from getting wet. Also, when the inner surface of the main body is wet and placed in a standing posture, the bent shape that extends from the inner surface of the seal lip of the seal member accepts and accumulates the condensed water that is transferred down, even if water may be transferred. Since the groove effect is exhibited, it is possible to prevent the dew condensation water that flows down from getting wet around the stationary part of the lid.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings for understanding of the present invention. However, the present invention is not intended to limit the scope of the present invention to the following embodiments, but is merely an illustrative example, unless otherwise specified.

  The lid 5 of the water heater of the present embodiment shown in FIG. 1 is plug-fitted so that it can be attached to and detached from the opening 4b as a recessed portion at the upper end of the body 4 where the water heater is heated by the heater 1 in the water heater. A disc-shaped main body 201 that closes the water heater region opening 2b connected to the opening 4b of the container body 4 of the inner container 2 that forms a water heater region from above is provided. Or, it has an attachment / detachment part 12 that is grasped and attached to / detached from the body as a mechanical device, for example. A part in the circumferential direction around the outer periphery of the main body 201 is located on substantially the same plane including at least one of a planar portion, a line-shaped portion, and a dotted portion, and the main body 201 is directed to the upper surface side and the inner surface side. As shown in FIG. 3, a stationary portion 203 that can be placed in an upright posture is formed by preventing falling and rolling to the left and right.

  The lid 5 has a large thickness between the inner surface and the upper surface because the main body 201 is plug-fitted to the container body 4, so the contents inside the lid 5 are as shown in FIGS. 1 and 2. The discharge passage 6 for pouring the liquid to the outside, the steam passage 8 for releasing the steam generated by the boiling water, and the lid 5 with or without the locking or unlocking of the lid 5 to the container 4 side. In addition to the advantage that it is easy to incorporate the detachable part 12 to be attached to and detached from the opening 4b that is the recessed part of the vessel body 4, operation pieces 63a and 63a as operation parts of the detachable part 12 are provided on the inner surface side that is directly exposed to steam. The temperature rise on the upper surface side can be greatly suppressed. Therefore, the stationary portion 203 that places the main body 201 in the standing posture can prevent the rolling in the direction in which the lid 5 rolls to the left and right, and can take an unnecessarily wide rolling prevention width or interval A as shown in FIG. 2 and 3 with a width or interval B to prevent the body 201 from being in a standing position, as shown in FIGS. The upper surface of the lid 5 including the operation side of the detachable part 12 that is stably placed and operated or gripped from the upper surface side of the main body 201 can be kept open together with the inner surface without being touched by anything else. .

As a result, the lid 5 has a main body 201 that is plug-fitted and has a large thickness. The lid 5 has a normally closed valve 84 that is easy to stop at the time of falling, and a water stop valve at the time of falling that prevents abnormal pressure increase. Steam passage 8 with 14, opening 4 b as a recessed portion of the container body 4 with or without the locking or unlocking to the container body 4 side to prevent inadvertent dropping The body 201 has a built-in detachable part 12 that is detachably attached to the main body 201, and that can greatly suppress the temperature rise on the upper surface side including the operation pieces 63a, 63a as the operation parts of the detachable part 12 and is convenient for ensuring safe use. The main body 201 is stable in a small plane space in an upright position with the stationary portion 203 that takes advantage of the large right-and-left dimension perpendicular to the paper surface of FIG. 1 and the thickness in the height direction shown in FIG. From the upper surface side of the main body 201 or And the upper surface of the lid 5 including the operation side of the detachable portion 12 to be gripped, together with the inner surface that is often wet at the highest temperature, and the open surface that is not blocked without being touched by others, and the inner surface is placed In addition to solving the problem of surface and wetting, a series of handling such as removal, placement, lifting from the placement state, and remounting of the lid 5 operates or grips the detachable portion 12 to touch the inner surface of the lid 5. It can be done easily and safely on the outer side only. Further, the mounting in the standing posture has an advantage that the temperature can be lowered quickly to a temperature at which there is no problem even if it is touched by promoting heat dissipation to the surroundings.

  Here, the stationary portion 203 does not need to be a plane, and at least three stationary points satisfy the rolling prevention width or interval A and the tipping prevention width or interval B, and are oriented to stabilize the main body 201 in the standing posture. The flat surface 204 may be on the flat surface 204, but the flat surface 204 stabilizes the main body 201 in a posture inclined forward toward the inner surface as shown in FIG. It can be opened. Thus, the stationary portion 203 does not have to be a plane, and at least three or more stationary points satisfy the rolling prevention width or interval A and the tipping prevention width or interval B, so that the main body 201 is stabilized in the standing posture. The flat surface 204 stabilizes the main body 201 in a posture tilted forward toward the inner surface as shown in FIG. The lid 5 can be easily placed and lifted from the stationary state by operating or grasping the attaching / detaching portion 12 in the upward open state. At the same time, the stationary portion 023 is provided from the substantially upper surface side to the substantially inner surface side of the main body 201 as shown in the triangular plane 204 on which the stationary portion 203 is located in FIG. Thereby, the fall prevention width or interval B of the stationary portion 203 can be ensured to be large by using almost the entire thickness of the main body 201. Further, the falling stop valve 14 of the steam passage 8 does not exceed the inner side of the stationary part 203b on the inner surface side of the lid body 5 in the upright standing posture of the lid body 5 but is positioned closer to the inner side. Thus, it is easy to stabilize the lid body 5 toward the forward tilt posture side. For that purpose, it is preferable to form the water stop valve 14 at the time of the fall with a material having a specific gravity larger than that of resin such as metal or ceramic. In addition, the dew condensation water inside the steam outlet 47 on the upper surface of the lid 5 of the steam passage 8 is easily transferred back to the inside due to the inclination of the standing lid 5 and is difficult to leak to the outside.

  In order to satisfy this, in the present embodiment, a hollow body 201 is formed by the lid 5 and the lower plate 71 and the upper plate 70 fitted and elastically engaged or screwed to the lower plate 71 from above. By using this, it is formed in a line shape that protrudes slightly rearward at the rear portion of the upper plate 70 and satisfies the rolling prevention width A, and is directed to the left-right direction perpendicular to the center line 205 in the front-rear direction in plan view. A point-like placement which becomes a grounding point in a stationary state in a standing posture at the outer peripheral portion of the front end of the main body 201 formed by the circular peripheral wall 45 formed between the stationary portion 203a and the upper plate 70 of the lower plate 71. It is distributed in two places, part 203b. This is because the main body 201 is plug-fitted to the container body 4 so that the peripheral wall 45 has a small diameter and the upper plate 70 has a larger diameter, and the plug-fitted boundary portion with the container body 4 is on the upper side. Using the relationship of providing an exterior covering with a protruding portion from the peripheral wall 45 of the plate 7, the orientation of the plane 204 on which the lid body 5 shown in FIG. We are satisfied only by forming the portion 203a. Further, the upper plate 70 is formed by integrally forming a pouring part lid 70a covering the spout 13 formed at the upper front part of the container body 4 and a protruding part forming the line-shaped stationary part 203a toward the rear part. Yes, the front and rear direction of the lid 5 can be easily seen by the user. Further, the fitting as shown in FIG. 1 with the spout 13 of the pouring part lid 70a and the notch 206 formed in the rear part of the peripheral wall of the opening 4b of the container 4 of the line-shaped stationary part 203a protruding rearward. By fitting, positioning of the lid 5 in the fitting direction to the opening 4b of the container body 4 and positioning to the fitting position can be performed. However, it is not essential that the line-shaped stationary portion 203a protrudes rearward from the flange portion of the upper plate 70, and the flange portion can be formed in a straight shape when viewed in plan, and prevents rolling. Two point-like stationary parts that satisfy the rolling prevention interval A instead of the width A and are separated from each other can also be provided. For this purpose, it can be formed by, for example, denting both ends of a line-shaped stationary portion 203a that is a straight line in plan view into a convex arc shape toward the front. The difference in diameter of the lid body 5 in which the stationary portions 203a and 203b are provided in a distributed manner on the upper surface side and the inner surface side of the lid 5 can also be realized by a step formed by the same member.

  Here, the stationary portion 203 is on the upper surface side of the main body 201, and the left and right line-shaped portions satisfying the rolling prevention width or interval A in the circumferential direction that can prevent the main body 201 from rolling left and right, or The rolling prevention width or rolling prevention interval A at the two point-like portions in the left-right direction satisfying the rolling prevention interval A in the circumferential direction that can prevent the main body 201 from rolling and the circular side end on the inner surface side of the main body 201. Satisfying the fall prevention interval B that can prevent the body 201 from falling to the upper surface side and the inner surface side at the middle point C, can be a single point-like portion that is a portion facing the axis 202 direction of the body 201, As a result, a circular end portion on the inner surface side of the main body 201 can be obtained simply by providing a line shape or two point-like portions satisfying the width A or the width A for preventing rolling to the left and right on the upper surface side of the main body 201 having a normal circular shape. Can be circumferential part realizes the stationary portion 203 to position the main body 201 in the standing posture with one of the point-like portion 203b formed. As a result, the peripheral wall 45 of the main body 201 can be formed simply by providing a line-shaped or one point-shaped stationary portion 203a that satisfies the width A or the distance A to prevent rolling to the left and right on the upper surface side of the main body 201, which is a normal shape. The stationary part 203 that places the main body 201 in a standing posture with one point-like part stationary part 203b formed by a part in the circumferential direction of the circular side end on the inner surface side can be realized with almost no change in the circular normal form. In this case, as the stationary point is closer to three or more points, stable stationary can be achieved without the influence of surface distortion and the like, and the prevention of falling is facilitated.

  Further, the attaching / detaching portion 12 includes a pair of left and right engaging recesses 65 shown in FIGS. 2 and 3 at the inner surface of the opening 4b at the plug fitting position of the main body 201 to the container body 4 shown in FIGS. 65 and a pair of engaging members 63, 63 that engage with the urging force of the spring 64 shown in FIGS. 4 and 5 to lock the main body 201 at the plug fitting position, and the engaging members 63, 63 A pair of left and right operating portions 63a and 63a as a pair of left and right operating portions that are brought into and out of contact with each other between a separating position and an approaching position approaching from the separating position in conjunction with the stopping and unlocking operations. 63a is formed on the upper surface of the main body 201, and the gripping operation is performed between the two positions so that the gripping operation is performed from the separated position to the approach position through the operation windows 74 and 74 shown in FIGS. In the position facing the operation windows 74, 74, the main body 201 is locked, unlocked, and worn. , It is so subjected to carry.

  Thus, when the main body 201 is plugged into the opening 4b of the container body 4, the left and right engaging members 63, 63 are elastically engaged with the engaging recesses 65 on the left and right of the inner surface of the opening 4b of the container body 4 by the urging force. Thus, the main body 201 is locked in the closed state. In this state, the left and right operation pieces 63a, 63a facing the operation windows 74, 74 on the upper surface of the main body 201 are picked by the thumb 61 and the index finger 62 through the operation windows 74, 74, and the figure is shown from the separated position shown in FIG. When the gripping operation is performed against the reaction force caused by the urging at the approach position shown in FIG. 5, the engagement members 63 and 63 are released from the engagement recesses in conjunction therewith, so that the locking is released. , 63a can be removed from the opening 4b with the gripping operation being carried out, and it can be carried as it is to place the stationary portion 203 at a desired position and leave the lid 5 in the standing posture.

In addition, a seal member 21 made of silicon rubber or the like that is attached to the inner surface side end of the main body 201 and press-contacts the water heater region opening 2b of the container body 4 to seal between the two is provided. A cross section that extends from the base portion 21a attached to the inner surface side end portion of the 201 toward the outer peripheral portion of the inner surface of the inner surface of the main body 201 while expanding from the inner peripheral portion toward the outer peripheral portion and further to the inner side. The seal lip 21b has a surface-bending shape, and the seal lip 21b is pressed against the boiling area opening 2b of the container body 4 so as to seal between the two. As a result, the seal member 21 mounted on the inner surface side end of the main body 201 is connected to the hot water region opening 2b of the container 4 at the innermost part plugged into the opening 4b of the container 4, as shown in FIG. Since the pressure is tightly pressed and sealed to prevent water leakage from the inner surface of the main body 201 to the upper surface side, it is possible to prevent the outer periphery other than the inner surface and the inner surface of the seal member 21 from getting wet. Further, the sealing member 21 has a cross-sectionally bent sealing lip 21b that extends inward from the inner periphery of the inner surface of the main body 201 to the inner peripheral side by a cross-sectionally bent shape that has a bent portion on the outer peripheral side. When the lid 5 is placed in a standing posture, the condensed water that flows down the inner surface is received and stored, so that the condensed water that falls down can be prevented from getting wet around the stationary portion 203 of the lid 5. Here, the point-like stationary part 203 b can be one point on the outer periphery of the seal member 21.

  By the way, the water heater according to the present embodiment is an example of a so-called electric kettle that does not have a heat retention control function, that is, is simply heated and stored as it is, and is provided with a handle 9 on the body 4. It is a handy electric kettle that can be handled easily. In addition, the container 4 covers an inner container 2 which is a kettle container with an outer case 3. Therefore, unlike a normal kettle, the user does not touch the kettle directly to get hot feelings or burns, the heat insulation due to the outer case 3 being made of resin, the inner container 2 and the outer case 3. The temperature of the outer surface of the container 4 can be suppressed by helping the air insulation between them, 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 2 is closed by the lid 5, and the content liquid can be poured out only when the normally closed valve 84 of the opening / closing mechanism 7 is opened in the pouring path 6 provided in the lid 5, and the non-pouring including the time of boiling water is not performed. Even if the container 4 falls down, the outflow of the content liquid through the pouring channel 6 can be prevented. Further, the steam passes through a predetermined steam passage 8 provided in the lid 5, and a predetermined safe position on the predetermined path, specifically, the operation unit 11 from the outside of the lid 5 of the opening / closing mechanism 7 and the lid of the lid 5. 5 Since it is made to discharge | release in the rear part of the cover body 5 shown in FIG. 1, for example, away from the position in which the external operation piece 63a of the attachment / detachment part 12 from the outside is provided, it is unlimited from the spout 13 of the container body 4 The risk of being released is suppressed, and the water stop function at the time of the fall, that is, the water stop valve 14 provided at the time of the fall in the steam passage 8 moves to the position where the steam passage 8 is blocked in response to the fall of the body 4. With the function, it is possible to prevent the content liquid from flowing out through the vapor passage 8 even if the container body 4 falls.

  However, this alone does not solve the problem of maintaining the bulky form of the container body 4, reducing the remaining amount at the time of pouring, and increasing the volumetric efficiency. In order to eliminate this, in the present embodiment, the lid body 5 is made to pour the content liquid 16 from the outlet 15 opened in the inner container 2 toward the outlet 17 toward the upper front end of the container body 4. 1, a pouring path 6 as shown in FIG. 1, an opening / closing mechanism 7 as shown in FIG. 1 that opens and closes the pouring path 6, and a water passage function as shown in FIG. 8 is provided. In addition, the inner container 2 has a cylindrical shape having a substantially straight body as shown in FIG. 1, and the sealing member 21 of the lid body 5 comes into contact with the predetermined sealing position 2 a of the container body 4 from above. In the region surrounded by the sealing member 21 of the lid body 5, the outflow port 15 has a front portion of the opening edge in the vicinity in plan view with respect to the front portion of the hot water region port portion 2 b of the inner container 2. It is provided to be located.

In this way, the inner container 2 has a cylindrical shape with a substantially straight body, and the seal member 21 of the lid 5 is closed by contact with the predetermined seal position 2a from above. The mouth portion 2b of the inner container 2 does not require an inner fitting with the opening 4b of the vessel body 4 and the shoulder portion 4a forming the spout 13 or the lid body 5 side, or wrapping inwardly. In the region surrounded by the sealing member 21, the front portion of the opening edge of the outlet 15 of the pouring channel 6 is located in the vicinity of the front portion of the boiling area port portion 2 b of the inner container 2 in a plan view. It is easy to make the space between each other, and the remaining amount with respect to the angle of tilting the container body 4 when the content liquid 16 is poured out can be made smaller than in the preceding example by the amount of the reduction. Thereby, the remaining amount when the container body 4 is tilted to the horizontal is significantly reduced. Further, the diameter of the upper end portion of the inner container 2, that is, the inner diameter is the same as or substantially the same as the diameter of the trunk portion, and the seal member 21 of the lid 5 is received by the shoulder portion 4 a of the container body 4 at the upper end portion of the inner container 2. Along with the lid body 5 that closes the inner container 2 by abutting from above to the flange 2a, which is a predetermined outward sealing position formed in this way, the inside diameter of the body 4 of the vessel body 4 becomes large, and the lid body 5 The pouring path 6, the opening / closing mechanism 7, and the steam path 8 satisfy the functions required for them, and are easily arranged in a concentrated manner.

  As a result, the inner container 2 having a substantially straight body portion is closed by contact from above with the flange 2a of the seal member 21 of the lid 5 and is surrounded by the seal member 21 of the lid 5 , It is easy to bring the front part of the hot water boiling region mouth part 2b of the inner container 2 and the front part of the opening edge of the outlet 15 of the pouring channel 6 close to each other, and the remaining amount with respect to the tilt angle of the container body 4 is reduced. The content liquid is efficiently drained at a small inclination angle of 4 and is easy to use. In addition, the lid body 5 that abuts the seal member 21 on the upper end portion of the large diameter, which is substantially equal to the diameter of the body portion of the inner container 2 and enhances the volumetric efficiency, becomes large without the bulkiness of the container body 4, and overlaps vertically. None, that is, without bulkiness, satisfying that the pouring path 6, the opening / closing mechanism 7, and the steam passage 8 are centrally arranged to satisfy the functions required for the lid 5, The circumference can be made slimmer than the previous example.

  In addition, since the sealing position is the outward flange 2a bent outward, a wide contact surface with the sealing member 21 that contacts from above is provided, and the sealing performance can be further improved. In order to ensure the sealing performance of the seal 21, it is suitable to eliminate the need for a seal structure that projects and seals inside the upper end 2 a. Further, as shown in the figure, the outward flange 2a is supported from below through a seal packing 22 on a step portion below the opening 4b of the shoulder 4a, so that there is no internal fitting with the inner container 2 on the body 4 side. It is suitable for connecting both.

  In this case, as shown in FIG. 1, the bottom portion 42 and the content of the bottom portion 42 and the contents are applied to the lower end of the body portion 41 integrally molded with the shoulder portion 4a and the body portion 4a1 of the container body 4 from the bottom. By connecting the bottom of the container 2 with the screw 23, the assembly of the container 4 can be easily performed and maintenance is also possible. Of course, fixing the heater 1 to the bottom of the inner container 2 is advantageous in terms of heating efficiency such as adhesion, and the internal power supply unit 24 to the heater 1 is externally fixed to the bottom 42 side. Conveniently, the power supply device 25 can be connected by direct fitting as shown in the figure. However, prior to the connection between the main body portion 41 and the bottom portion 42, the heater 1 side and the internal power supply device portion 24 need to be connected in advance, and the connection is between the unconnected main body portion 41 and the bottom portion 42. Therefore, a wiring length is required that enables operations such as connection release and parts replacement by separating both the main body portion 41 and the bottom portion 42.

  Further, the connecting structure in the vertical direction between the main body portion 41 and the bottom portion 42 is formed between a holding hole 41a opened downward on the main body portion 41 and a holding hole 42a opened upward on the bottom portion 42 as shown in the figure. In addition, the handle 9 can be sandwiched and assembled, and it becomes easy to provide the handle 9 on the container body 4, and it is possible to perform independent maintenance by removing it.

  A steam sensor 26 serving as a steam detector 26 that detects boiling by touching the steam from the steam passage 8 and turns off the heater 1 is provided to detect boiling and turn off the heater without requiring complicated control or circuitry. For the sake of safety, a steam sensor 26 is provided on the side of the container body 4 so that the electrical connection is not related to the attachment / detachment of the lid body 5, but a part of the steam is removed from the steam passage 8 of the lid body 5. In order to guide the steam sensor 26 to the steam inlet path 31 of the steam inlet path 36 on the container body 4 side, the lid body 5 is plugged into the opening 4b at the upper end of the container body 4 from above on the axis line and attached / detached. In the plug fitting area, the steam passage 8 and the steam introduction path 36 are provided on one of them between the connection port 8c of the lid 5 and the steam introduction port 4d2 on the inner surface of the opening 4b of the vessel body 4. It will be connected so as not to leak steam.

  The handle 9 is formed in a hollow having a substantially rectangular loop including its mounting base portion 9a, detects boiling by touching the upper part of the handle 9 and opens a power supply path from the internal power supply device 24 to the heater 1 to supply power. The steam sensor 26 is built in, and this also serves as an on / off switch for power feeding. In this connection, the upper part of the handle 9 is provided with a steam introduction path 31 through which steam is introduced and brought into contact with the bimetal 26a portion of the steam sensor 26 from the steam passage 8 of the container body 4, and the steam that has touched the bimetal 26a is placed in the container. The U-turned steam and the condensed water that has flowed back to the body 4 side are led from the steam introduction path 31 to the lower part of the handle 9 through the return path 32 formed in the mounting base 9a, and from the outlet 32a there to the outside I try to let it flow.

  Here, as shown in FIG. 1, the opening / closing mechanism 7 is positioned in the vicinity of the rear side of the spout 17 for pouring the content liquid toward the front end of the upper body 4 of the lid 5. Thus, since the opening / closing mechanism 7 is located in the vicinity of the rear side of the spout 17 of the lid body 5, the whole from the outlet 15 to the spout 17 of the spout path 6 that is opened and closed by the open / close mechanism 7 is covered by the lid. The space can be set close to the front side of the body 5, and the operation part 11 of the opening / closing mechanism 7 can be used as the vicinity of the spout 17 or the spout 13 connected to the spout 17, thereby enhancing the visual relevance of both. That is, since the opening / closing mechanism 7 is positioned in the vicinity of the rear side of the spout 17 of the lid 5, the entire portion of the pouring path 6 that is opened and closed by the open / close mechanism 7 from the outlet 15 to the spout 17 is the lid 5. It is possible to install a small space by approaching the front side, and it is advantageous for installation of other necessary equipment, and the operation part 11 of the opening / closing mechanism 7 is close to the spout 17 or the spout 13 connected to it as shown in the illustrated example. The high visual relevance of both makes it easy to use without misoperation.

  Further, since the steam passage 8 is provided on the rear side of the lid body 5 opposite to the opening / closing mechanism 7, the steam passage 8 can be installed with a small space near the rear portion of the lid body 5, and the operation section 11 is also used for discharging steam to the outside. It is enough away from. In this way, the steam passage 8 is located on the rear side of the lid body 5 opposite to the opening / closing mechanism 7 side that is frequently externally operated by the operation unit 11, and the lid 5 can be enlarged to help the steam. Even when it is discharged to the outside, it is sufficiently distant from the operation unit 11 and the safety of the user against the steam can be achieved. A metal inner lid 43 is attached to the lower side of the bottom plate 71 where the outlet 15 of the lid 5 is opened with screws 44 or the like as shown in FIGS. 1 and 4 to protect the resin lid 5 from thermal protection. The sealing member 21 provided around the peripheral wall 45 of the lid body 5 is sandwiched between the outer periphery of the lid body 5 and the outer periphery of the inner lid 43 by using what has been done, and the bottom plate of the lid body 5 A valve chamber 46 is formed between the rear portion 71 and the inner lid 43 to accommodate the water stop valve 14 at the time of falling.

  Moreover, the attaching / detaching portion 12 is provided between the opening / closing mechanism 7 of the lid 5 and the steam passage 8 as shown in FIG. Thereby, the attaching / detaching part 12 of the lid 5 can be installed by using the dead space 52 between the opening / closing mechanism 7 and the steam passage 8 on the front and back of the lid 5, and the center position of the lid 5 in the front-rear direction Thus, the lid 5 can be easily locked on the side of the vessel 4 without being biased in position and locking force, and can be locked stably. Further, the lid 5 can be easily handled without being biased even when the lid 5 is attached and detached with the release of the lock.

  Specifically, the lid body 5 has a certain amount of play in the recessed portion of the opening 4b as shown in FIG. 1 formed above the step 4c below the opening 4b of the shoulder portion 4a of the vessel body 4. It can be attached / detached by the attaching / detaching part 12 together with the fitting with the. The above-mentioned fitting with play is detachable in a so-called plug fitting type in which both the lid body 5 and the recessed portion have a gentle inclination of a draft angle during resin molding, and are fitted in the axial direction and removed from the fitting. I am going to do it.

As shown in FIGS. 4 and 5, the attaching / detaching unit 12, which attaches / detaches the lid body 5, exposes the lid body 5 and individually separates the thumb 61 and the index finger or ring finger 62 facing the thumb 61. A pair of left and right engaging members 63 having outward operation pieces 63a, 63a adapted to be hung on the lid 5 are provided in the lid body 5, and the engagement of each engaging member 63 is performed by a spring 64 which is acted between these engaging members 63. 63 pieces
b always protrudes from windows 45a provided at two places on the left and right of the diameter line of the peripheral wall 45 of the lid 5. Opposing to this, the engaging recesses 63b engaging the protruding engaging pieces 63b at two places on the diameter line of the peripheral surface of the recessed portion formed by the opening 4b of the shoulder 4a of the vessel body 4 are shown in FIG. It is formed as shown in FIG.

  As a result, when the finger is put on the pair of left and right operation pieces 63a, the detachable portion 12 can be received by the repulsive force of the spring 64 without retracting the engaging member 63 against the spring 64. Can be easily and stably gripped and can be handled freely. Accordingly, the lid 5 can be gripped by the attaching / detaching portion 12 and can be plugged into the recessed portion 4d of the container body 4 in the axial direction from above as shown in FIGS. In the middle of the plug fitting, the detachable part 12 has an engaging piece 63b protruding from the peripheral wall 45 of the lid 5 abutting on the opening edge of the recessed part 4d from above. However, the engaging piece 63b receives the pushing force toward the retreat side by the opening edge of the recessed portion 4d because the lower surface of the projecting portion is the inclined surface 63b1, and retreats against the spring 64 as shown in FIG. Be made. For this reason, the lid 5 can be further plug-fitted into the recessed portion formed by the opening 4b only by applying a light pushing force without any special operation. The plug fitting final stage lid 5 has a seal lip 21b of the seal member 21 brought into pressure contact with a flange 2a at the upper end of the inner container 2 on the side of the container 4 by a predetermined amount, so that the inner container 2 is shown in FIG. close. Simultaneously with this closed state, the engaging piece 63b of the engaging member 63 faces the locking recess 65 on the inner surface of the recessed portion 4d as shown by the phantom line in FIG. Since it is released, it is projected again from the peripheral wall 45 by the spring 64 and engages with the locking recess 65. As a result, the engagement piece 63b prevents the lid 5 from being pulled upward by the flat upper surface being caught by the same flat lower surface of the locking recess 65, and the repulsive force of the seal member 21 causes the engagement portion 63b to be pulled out. The gap can be kept in the pressure contact state in the vertical direction. That is, the lid 5 can be locked in the closed state and stabilized in the vertical direction. However, the plug fitting to the recessed portion 4d of the lid 5 can be performed with the retraction of the pair of engaging members 63 by manual operation.

  Here, the locking recess 65 is designed so that the receiving amount of the engagement piece 63b is received at a push-back position that gives the spring 64 an appropriate compression state, so that the recess 4d has a play and is plug-fitted. Since the left and right centripetal function of holding the lid 5 being held at the neutral position where the spring force of the spring 64 balances left and right is exhibited, the lid 5 can be stabilized in the neutral position and the axial position in the left-right direction. In connection with this, the spout 13 formed in the shoulder 4a of the vessel body 4 forms a step 4d1 that is lowered toward the opening 4b at the base thereof as shown in FIGS. The spout 17 is received and connected. As a result, the content liquid poured out through the pouring path 6 of the lid 5 flows from the pouring port 17 to the pouring port 13 and is poured out. 17 is small, and the lid 5 can be easily handled as a single unit, and the content liquid to be poured out by connection with the spout 13 can be poured out from a position away from the outer surface of the body part of the container 4 by a necessary amount. In addition, the fitting of the spout 17 with the stepped portion 4d1 exhibits a positioning function around the axis 202 when the lid 5 is plugged into the opening 4b from above, and at the end of the plug fitting, The function of preventing the body 5 from rotating around the axis is also exhibited. Accordingly, the lid 5 rattles around the axis, assuming that the engagement between the engagement piece 63b and the locking recess 65 has a moderate play for facilitating engagement / disengagement around the axis of the lid 5. This can be prevented.

As shown in FIGS. 1, 4, and 5, the lid 5 is further provided with an operation window 73 that exposes the operation portion 11 of the opening / closing mechanism 7 in addition to the vapor outlet 47 described above, and the detachable portion 12. An attaching / detaching operation concave portion 74 for allowing the operation piece 63a to protrude and performing the attaching / detaching operation, a spout lid 70a extending above the spout 17 and spout 13, and a stationary portion 203a are integrally formed. In addition to the valve chamber 46 described above, the lower plate 71 is formed between the lower plate 71 and the intermediate plate 75 sandwiched between the upper plate 70, the intermediate plate 75, and the intermediate plate 75. The auxiliary intermediate plate 76 shown in FIG. 1 sandwiched between the upper plate 70 and the vapor passage 8 having the liquid reservoir 8a is formed, and the inside of the inner container 2 is adjoined to the rear portion of the pouring passage 6. By communicating with the liquid reservoir 8a of the steam passage 8, the outside air is sucked into the inner container 2 from the steam discharge port 47 when the content liquid 16 is poured out, and the inside of the inner container 2 does not become negative pressure and the content liquid 16 is poured. An intake passage 77 is formed for smooth exit.

  Here, in the detachable portion 12, the engaging member 63 is fitted into the connecting boss 70a as shown in FIG. 6 with the window 63c of its own as shown in FIG. 6 and the lower plate 71 of the upper plate 70 as shown in FIGS. In this state, it is sandwiched between the upper and lower plates 70, 71 and protrudes from the guide portion 8 b protruding upward from the liquid reservoir 8 a formed by the auxiliary intermediate plate 76, and the lower surface of the upper plate 70 so as to face this. The guide convex part 70b provided is guided from the left and right sides so that the cover body 5 is smoothly advanced and retracted so that the lid 5 is smoothly attached and detached with the unlocking. However, the guide on the front side of the engaging member 63 may use another part instead of the guide convex part 70b, for example, another structural protrusion, and depending on the case, it may be moved upward by the liquid reservoir 8a. It may be a protruding portion.

  Further, the opening / closing mechanism 7 has a valve shaft 84a interposed in two upper and lower O-ring type seal members 85 in a sliding hole 83 as shown in FIG. 1 formed concentrically with the outlet 15 of the intermediate plate 75. The valve 84 is supported so as to be slidable up and down, and is provided with a valve 84 that opens and closes the outlet 15 from the lower side through a seal member 86 by a lower end valve body 84b of the valve shaft 84a. The movable cam member 87 is rotatably connected and urged upward by a spring 88, and is guided to the inner periphery of a guide cylinder 70c formed on the lower surface of the upper plate 70 so as to guide the vertical sliding of the movable cam member 87. A plurality of fixed cams 91 are formed so as to switch between opening and holding of the valve 84 in the circumferential direction and release of opening and holding, and a plurality of movable cams projecting radially on the outer periphery of the movable cam member 87. 87a can be engaged and allowed Each time the cam member 87 is pushed down against the spring 88, a rotation position where the valve 84 is opened and locked to the opening holding position, and a rotation that releases the opening holding and can return to the upper movement to close the valve 84. It is designed to repeat switching to the position sequentially. Such a configuration has long been known as a so-called knock mechanism that switches between a protruding state and a retracted retracted state of a ballpoint pen, and is also known in Japanese Utility Model Publication No. 61-160831, and requires special features. Therefore, detailed illustration and description are omitted here.

  Particularly, as shown in FIG. 1, the operation portion 11 has a cap shape that is fitted to the movable cam member 87 so as to be relatively rotatable from above, and the outer peripheral engagement piece 11a of the operation window 73 as shown in FIG. The movable cam member 87 is pushed down by engaging with the opening edge from the inside, and the movable cam member 87 is pushed down, but the arc rotation of the movable cam member 87 at that time is not affected and is not affected. ing. Further, the valve 84 also prevents the rotation of the valve 84 by fitting a guide pin (not shown) that projects integrally on the valve body 84b and the guide hole of the lower plate 71, and does not affect or influence the rotation of the movable cam member 87. I'm trying not to be. The seal member 86 provided on the valve body 84b is separated from and in contact with the lower end opening of the intake passage 77 adjacent to the outflow port 15, and while the valve 84 is closed, that is, when the discharge passage 6 is closed. The inner container 2 is closed so as not to be discharged through a route other than the predetermined steam passage 8.

  Finally, as shown in FIG. 1, the container body 4 has a stationary surface 101 on the lower surface of the bottom plate 42. The stationary body 101 is installed on the power supply table 102 by the stationary surface 101, and an external power supply device provided there. 25 is connected to an internal power supply device 24 so that it can be heated by being supplied with power from a household power source connected to the power supply stand 102. After boiling, it is removed from the power supply stand 102 and carried by the handle 9, and can be moved to the required position. Can be used for repeated dispensing on the spot.

In the water heater, the lid body is of a type that is detachable by gripping operation from the upper surface, but the detachable portion is in an upright posture where both the upper surface on the inner side and the inner surface to which condensed water adheres are opened. Can be fixed, easy to handle, and avoids wetness and sanitary problems in handling.
