  If a steam outlet is provided on the outer shell surface of the lid and the steam is discharged to the outside, the steam outlet is hot, which may cause burns. Moreover, the condensed water adhering to the steam outlet may scatter or sag. In order to prevent this, there is a method in which steam is once introduced into a small box-shaped steam buffer and then the steam temperature is lowered and discharged, but in such a case, the number of members increases and the structure becomes complicated. , Requires space and increases costs.

  As a method for solving such a problem, it is possible to avoid opening the steam directly to the atmosphere by opening the steam outlet to the lid lower plate and discharging the steam between the lid lower plate and the container body side. .

  However, in such a case, when the steam outlet is clogged with foreign matter, the internal pressure of the container main body is increased and hot water in the container main body may be discharged out of the container by natural discharge.

  The problem to be solved is to provide a steam passage that communicates the inside of the container body and the atmosphere, and an on-off valve is provided in this steam passage, and this on-off valve is provided so as to be interlocked with the operation portion of the switch of the air pump. In addition, in the electric pressurized pouring liquid container, the vapor from the vapor outlet of the vapor path is not directly released to the atmosphere, and the vapor outlet is not clogged.

  According to the first aspect of the present invention, air is fed into the container main body by an electric air pump, the content liquid in the container main body is poured out, and the inside of the container main body and the atmosphere are connected to the lid of the container main body. An electric pressurized discharge type liquid container provided with an exhaust passage for communicating steam, an open / close valve in the exhaust passage, and an open / close valve interlocked with an operating body of a switch of the air pump. The steam discharge portion of the exhaust passage is an electric pressure pour-out type liquid container that is opened below a lid lower plate of the lid.

  The invention according to claim 2 is the electric pressurized dispensing liquid container according to claim 1, wherein the vapor discharge portion is formed in a plurality of small holes.

  According to the first aspect of the present invention, the steam in the container is discharged below the lid lower plate, that is, into the space between the lid body and the container body by opening the steam discharge portion below the lid lower plate. The steam discharged to the space eventually diffuses from the gap between the lid and the container body and is discharged to the outside.

  Therefore, when the lid is closed, the steam discharge part is in a position that cannot be directly touched by humans, so there is little risk of burns due to steam, and water droplets condensing on the steam outlet of the lid bottom plate may be scattered, Even if it hangs down, it is between the lower lid plate and the container body, so there is no risk of contaminating the outside.

  And according to invention of Claim 2, it can prevent that a foreign material enters and blocks | closes a vapor | steam outlet by making the vapor | steam discharge | emission part of a lid lower board into a some small hole.

A spring 49, a coil spring that expands and contracts in the vertical direction in the embodiment, is interposed between the dispensing operation body 24 and the upper portion 43B of the holder 43. Accordingly, when the dispensing operation body 24 is pressed, this pressing force can be transmitted to the holder 43 via the relay member 48. The relay member 48 is provided with an interlocking portion 24A for pressing the switch 31A.

  A steam discharge pipe 50 is interposed between the secondary side hole 41 of the valve case 38 and the steam discharge portion 28 in the steam exhaust path 29. In the figure, reference numeral 51 denotes a lock / unlock button of the pouring operation body 24, and reference numeral 52 denotes an overturning water prevention valve provided in the middle of the pumping pipe.

  Further, the configuration of the on-off valve 26 will be described in detail with reference to FIG. A valve case 38 is provided on a steam vent primary side hole 39 provided in the lid lower plate 9B, and a steam vent secondary side hole 41 is provided on a side surface of the valve case 38. The valve case 38 is an assembly of three parts divided into a lower, middle, and upper part. The lower part 38A is disk-shaped, and a valve seat 40 is provided in the center of the plane, while the central part 38B is on the lower side. Is provided with a steam vent secondary side hole 41 and has a cylindrical shape with a large diameter on the upper side, and the upper part 38C is a cylindrical shape penetrating the upper and lower sides of the upper part of the central part 38B. A fixing piece 38D for fixing to 9 is provided. In the drawing, reference numeral 38E denotes a communication portion that is provided above the upper portion 38C and communicates with the inside and outside. The holder 43 is also an assembly of two parts divided vertically, and a lower part 43A having a protrusion 44 on the inner periphery and opened in the vertical direction is slidable on the inner surface of the central part 38B so as to be movable up and down. It has a cylindrical shape, and its inner diameter is formed larger than the diameter of the valve body 42, so that the valve body 42 can move slightly in the holder 43. In the embodiment, the sliding area can be reduced not in the entire outer periphery but in part, so that the sliding resistance can be reduced. When the seat 44 is seated with the inner diameter of the projection 44 being smaller than the diameter of the spherical valve body 42, the valve body 42 is prevented from falling off. On the other hand, the upper part 43B of the holder 43 has a lid shape, and the inner side of the outer edge is fitted with the lower part 43A, and the outer side of the outer edge is provided so as to be engageable with the stopper 45. By stopping, the holder 43 is prevented from being pushed up by the spring 47 any more. In a state where the valve body 42 is seated on the tapered surface 44A, a gap 46 is formed between the valve body 42 and the center side of the upper portion 43B. Since the outer edge of the upper portion 43B slides on the inner surface of the upper portion of the central portion 38B, airtightness is maintained. As a result, the steam flowing in from the steam venting primary side hole 39 does not leak and the steam venting secondary side hole 41 It is possible to escape. The coil-shaped spring 47 is interposed between the upper surface of the lower portion 38A and the outer edge side of the lower surface of the lower portion 43A with its axial center (not shown) directed vertically, and the inner diameter of the spring 47 is The valve element 42 is larger than the valve element 42 so that the valve element 42 can pass through the spring 47. When the valve element 42 is seated on the tapered surface 44A, the center of the valve element 42 is substantially disposed on the axis of the spring 47. It has become so. The stopper 45 has a ring shape and is mounted on the inner edge of the upper opening of the upper portion 38C so as to face the axial center of the opening. Then, as shown in FIG. 8, the pressing force is transmitted to the upper part 43B through the upper opening of the upper part 38C via the relay member 48 in conjunction with the downward pressing of the dispensing operation body 24, whereby the holder 43 is The valve body 42 is pushed down, and the holder 43 is lowered in this way, so that the valve body 42 is seated on the valve seat 40 and closed. And it will be poured out.

  On the other hand, when the internal pressure of the inner cylinder 2 rises above a specified pressure in the valve-closed state, there is a space around the valve element 42 at this time. The pressure in the cylinder 2 is reduced. Then, the gas is exhausted along the steam exhaust passage 29 via the steam vent secondary side hole 41. For this reason, the internal pressure of the inner cylinder 2 does not become a set pressure or more at the time of pouring, and the content liquid can be poured while maintaining the pouring flow rate within a certain range.

  Next, the operation of the above configuration will be described. When opening the lid, the knob 20B on the opposite side of the knob 20B of the lock operating unit 20 that is substantially flush with the lid upper surface 9A is pressed downward, so that the knob 20B is tilted forward about the hinge shaft 20A. When the knob 20B is picked up and pulled backward while being raised, the action part 20C moves the lock claw 21 forward against the spring 21A and engages with the locking claw locking piece 22 By releasing the stop state and further lifting the knob 20B upward, the lid body 9 can be erected so as to face upward via the hinge member 23.

  Then, after gripping the detachable handle 18 and extracting the inner plug 12 from the mouth portion 3, hot water is accommodated in the inner cylinder 2 via the mouth portion 3 using a kettle (not shown) or the like.

  Next, the detachable handle 18 is picked, the inner plug 12 is inserted into the mouth portion 3 so as to insert the pumping pipe 10 into the inner cylinder 2, and the knob portion 20B is further picked and closed. At this time, the lock claw 21 can be locked to the lock claw locking piece 22 according to the spring 21A. Further, when the lid is closed, the lower end of the exhaust leakage preventing packing 32 is in close contact with the upper surface of the inner plug 12 so as to block the periphery of the upper end opening of the steam inner plug exhaust path 35 and thereby the steam hole 27 and the inner plug exhaust path. 35, and at the same time, the lower end of the air leakage prevention packing 33 is in close contact with the upper surface of the inner plug 12 so as to block the periphery of the upper opening of the inner plug air inlet path 36, thereby connecting the exhaust hole 34 and the inner plug. The air inlet path 36 can be airtightly connected.

  When the cover 9 is kept warm, the valve body 42 is separated from the valve seat 40. Therefore, the steam in the inner cylinder 2 is discharged from the inner plug exhaust passage 35, the exhaust leakage prevention packing 32, and the steam exhaust. It passes through the valve element 42 through the passage 29 and is exhausted to the outside from the steam discharge part 28, so that the inside of the inner cylinder 2 is maintained at normal pressure. The steam passing through the steam exhaust passage 29 passes through the steam discharge pipe 50 and from the hole 28A of the steam discharge portion 28 provided in the cover lower plate 9B, the cover lower plate 9B, the inner plug 12, and the tray portion 15 The steam discharged in the gap is cooled and becomes water droplets and stays at this location, or a part of the steam becomes low temperature steam and is released to the atmosphere through the gap.

  Next, when the lock / unlock button 51 is operated to press the unlocking operation body 24 which has been unlocked, the holder 43 is lowered and the valve body 42 is seated on the valve seat 40 to close the valve. 2 is sealed. Further, the switch 31A is closed via the interlocking portion 24A by the pressing of the pouring operation body 24, and the electric air pump 8 is activated, and the compressed air is sealed from the exhaust hole 34 to the inner cylinder 2 from the exhaust hole 34. Then, the pressure is fed into the inner cylinder 2 through the air leakage prevention packing 33 and the inner plug air feed path 36 to increase the internal pressure of the inner cylinder 2. The water accommodated by the internal pressure of the inner cylinder 2 rising by this pumping is discharged through the pumping pipe 10 and the water injection pipe 11.

  At this time, when the pressure in the inner cylinder 2 is relatively high, there is a space consisting of a gap 46 in the upper part of the valve body 42 made of a weight body. Can be reduced to an appropriate pressure.

  As described above, in the above-described embodiment, the steam in the container body 5 is discharged into the space between the lid body 9 and the shoulder member 6 by opening the steam discharge portion 28 below the lid lower plate 9B. There is little risk of burns due to steam, and even if water droplets condensed on the steam discharge portion 28 of the lid lower plate 9B are scattered or dripped, there is no possibility of contaminating the outside because it is between the lid lower plate 9B and the container body 5. Further, by forming the vapor discharge portion 28 of the lid lower plate 9B with a plurality of small holes 28A, foreign matter can be prevented from entering and blocking the vapor discharge portion 28, and the discharged vapor can be diffused.

  Moreover, the handle 18 for attaching and detaching the inner plug 12 is located on the upper surface of the inner plug 12 and is disposed in front of the vapor discharge portion 28, so that the inner plug 12 can be easily attached and detached by the handle 18, and the steam Steam from the discharge part 28 and the inner plug exhaust path 35 is prevented from hitting the hand. Further, by providing the hollow downward projecting portion 9 </ b> D inside the inner cylinder 2 on the lower surface side of the inner plug 12, the heat retaining performance of the inner plug 12 can be improved. Furthermore, the protruding length from the edge of the outer cylinder 4 at the outer edge of the bottom member 4A is such that the protruding length M on the rear side is larger than the front length L of the outer cylinder 4 (L <M). The container body 5 can be prevented from falling backward when the lid 9 is opened.

  Further, in the above embodiment, the valve case 38 that is open on the valve seat 40 provided with the steam vent primary side hole 39 provided on the lid lower plate 9B side is provided, and the valve case 38 is opened on the valve seat 40. A valve body 42 that can be raised and lowered is provided so as to be openable and closable. A valve body 42 and a holder 43 are provided in a valve case 38 so as to be raised and lowered, and the holder 43 is a protrusion serving as a second valve seat. The lower part of the valve body 42 faces the valve seat 40 so that it can be seated and is seated and held on the protruding part 44. Further, the valve seat 40 side and the holder are provided. A spring 47 is interposed between the spring 43 and the spring 47 so that the holder 43 is always urged upward to always open the valve. On the other hand, when it is desired to pour out, the pressing force downward from the pour operating body 24 can be transmitted to the holder 43 via the relay member 48. A steam vent secondary side hole 41 is provided in the lower portion of the side surface of the valve case 38, and a steam exhaust path 29 is connected to the steam vent secondary side hole 41. With such a configuration, in the electric air pot in which the inside of the inner cylinder 2 is pressurized by the pump 8 to dispense the content liquid, the pump 8 is activated when the dispensing operation body 24 is operated, and the pressure adjustment When the valve body 42 closes the valve seat 40 at the end of the steam hole 27, the pressure of the inner cylinder 2 can be adjusted and the content liquid can be poured out. Thus, when the dispensing operation body 24, which is a dispensing button, is pressed, the holder 43 is lowered, and the valve body 42 made of a metal ball is placed on the valve seat 40 to close it. There is a space around it, and when the pressure in the inner cylinder 2 is high, it moves finely and lowers the pressure in the inner cylinder 2. When the dispensing operation body 24 is pressed, the holder 43 is lowered and the switch 31A connected to the electric pump 8 is pushed almost simultaneously with closing the valve seat 40, the pump 8 is activated, and the content liquid is pressurized. Therefore, when the dispensing operation body 24 is pressed, the content liquid can be dispensed while maintaining the dispensing flow rate within a certain range.

  Further, by pushing down the cylindrical holder 43 interlocked with the dispensing operation body 24 and the valve body 42 consisting of a weight body held by the cylindrical holder 43, the valve body 42 is moved to the valve seat 40. Is supposed to be blocked.

  Further, an elastic member 40A is provided on the valve seat 40 which is closed by the valve body 42 made of a weight body. By doing so, in the elastic member 40A of the valve seat 40, when the valve seat 40 is made of resin, the pressure in the inner cylinder 2 is reduced even if the valve body 42 does not move finely due to micro unevenness on the resin surface. If the pressure is higher than the atmospheric pressure, the air escapes slightly, the pressure in the inner cylinder 2 decreases, and the amount dispensed decreases. By using the valve seat 40 as the elastic member 40A, the valve body 42 and the elastic member 40A are brought into close contact with each other, and the influence of micro unevenness is reduced, and the decrease in the amount of liquid dispensed when the temperature is low can be suppressed. Moreover, since the pressure of the inner cylinder 2 is high when hot water is poured out, the valve body 42 is finely moved to lower the pressure, so that even if an elastic member is used, the amount of pouring does not increase too much. Therefore, by using the elastic member 40A, the dispensing flow rate can be maintained within a certain range.

  In addition, an elastic body is interposed between the valve case 38 and the holder 43, and the valve body 42 is opened away from the valve seat 40 except during the pouring, and the pressure of the steam in the inner cylinder 2 is set to atmospheric pressure. I try to open it. As a result, various valve bodies 42 such as metal balls and triangular pyramids are inserted into the cylindrical holder 43, and the holder 43 is separated from the valve seat 40 by the elastic force of an elastic body such as a spring 47. Is held by. In this state, even when hot water is stored in the inner cylinder 2, the pressure in the inner cylinder 2 does not rise, and the content liquid is not naturally poured out.

  When the dispensing operation body 24 is released, the valve body 42 is pushed up by the repulsive force of the elastic body such as the spring 47, the cylindrical holder 43 is pushed up, the valve body 42 is separated from the valve seat 40, and the pressure of the inner cylinder 2 increases. It will not be poured out naturally without it. And since the repulsive force (elasticity) of the elastic body such as the spring 47 only lifts and holds the valve body 42, it is smaller than the force pushing the manual bellows pump, so the force pushing the dispensing operation body 24 is the manual bellows. It is much smaller than a pump type air pot.

  Furthermore, by providing the pump 8, the steam exhaust passage 29 with the on-off valve 26, the switch 31 </ b> A and its dispensing operation body 24 in the hollow portion inside the lid body 9, all electrical components are in the lid body 9. It becomes. If the cover body 9 can be removed from the container body 5, the container body 5 can be washed without water entering the electrical parts by removing the lid body 9 when washing the container body 5. Become.
