Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an electric hot water storage container of the type that allows the contents to flow out naturally by tilting the container.

(Prior Art) As shown in FIG. 4, this type of electric hot water storage container is configured to open and close an outlet c provided in a lower lid plate b by vertical movement of a valve body a.
Some devices are known that allow more liquid to be poured out.

In this device, the steam generated during heat retention and boiling is injected through a steam venting passage h that is detoured to communicate with the liquid injection passage e in the lid g, as shown by the arrow in Fig. 4. It is discharged to the outside from the liquid port f. Then, when the crown button d on the outer surface of the lid g is pressed to open the valve body a and the container is tilted, the liquid content is poured from the outlet c through the liquid injection passage e to the outside from the liquid injection port f. liquid.

During this liquid injection, when the container is tilted greatly and the liquid is poured all at once, the liquid that passes through the outlet c will flow to the lower lid plate b.
A small air hole j for intake air is provided in a part of the lower lid plate b to reach the central front part i of the lid.

(Problem to be solved by the invention) However, in the above conventional example, when the container is accidentally overturned while not injecting liquid, the liquid inside the container leaks into the steam vent passage.
There is a risk that the liquid may leak out through the injection port f, which is especially dangerous if it is boiling water.Furthermore,
If the steam generated during boiling enters the inside of the lid g from the air hole j, it will condense and cannot be easily removed or cleaned, causing unsanitary conditions such as adhesion of dust and the propagation of various bacteria. There is also the problem that the metal members inside the lid g are corroded.

Furthermore, if the container body is tilted greatly and the liquid is injected all at once, the liquid content will enter the lid g from the air hole j, causing the same problem as described above. Moreover, in the conventional example above,
The internal structure of the lid g is complicated because it is necessary to provide a detour to prevent the contents from flowing out when pouring liquid.

Therefore, an object of the present invention is to provide an electric hot water storage container with a simple structure that can solve the problems of the conventional example.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a passageway through which the content liquid naturally flows out when the vessel body is tilted, and a liquid injection port of this passageway is connected to the vessel body. In an electric hot water storage container that opens at the front of the body, a steam venting passage is formed at the rear of the lid of the container body, and a water stop valve is seated in a valve receiving part formed in the middle of the steam venting passage, Forming an inclined surface on the valve receiving portion to move or facilitate the movement of the water stop valve to the opposite valve port side depending on the inclination angle of the container body when pouring out the content liquid,
It is characterized in that the valve opening is closed by moving the water stop valve.

(Function) According to the above structure of the present invention, the water stop valve is normally seated on the valve receiving part and opens the valve port in the middle of the steam vent passage, so when the liquid inside the container is boiled or kept warm. The steam can flow out of the lid body through the steam vent passage, and the pressure inside the vessel will not rise abnormally.

In addition, when injecting the liquid content, the inside of the container tends to create a negative pressure, but since outside air is introduced into the container through the steam vent passage, negative pressure does not occur and the liquid can be poured smoothly. be able to.

Furthermore, when injecting the liquid by tilting the container, if the container is tilted suddenly, the liquid will tend to shift rapidly towards the lid, hitting the inner surface of the lid and reaching the rear side of the lid. However, since the steam vent passage is provided at the rear of the lid and located on the opposite side of the container from the liquid injection port, it is possible to delay the content liquid from reaching the steam passage as much as possible. However, the sloping surface formed on the valve receiver allows the water stop valve to move toward the valve port side or to move easily depending on the inclination angle of the container body, so the water stop valve is closed before the liquid content reaches the steam vent passage. Close the valve port as soon as possible, or even if the liquid content reaches the steam vent passage, it will be easily and quickly moved to the valve port side by the liquid content, and the valve port can be closed before the liquid content flows out. can.

(Embodiments) The present invention will be specifically described below based on embodiments shown in the drawings.

The embodiment of the present invention shown in FIGS. 1 to 3 relates to an electric hot water storage container of the type that allows the contents to flow out naturally by tilting the container body. An inner container 2 having a heater 1 wound around its lower side circumference is housed and held in an outer case 3 having an annular bottom plate 26 attached to its lower end to form a container body 4. The mouth portion 2a of the inner container 2 is connected to the upper end of the outer case 3 by an annular shoulder member 5, and a lid 6 is screwed to cover the shoulder member 5. The lid 6 consists of an upper plate 7 and a lower plate 8, and a metal cover 9 having openings 9a and 9b attached to the mouth 2a of the inner container 2 is attached to the lower surface of the lower plate 8, and is integrated therewith. When the cover 9 is opened and closed, the opening 2a is sealed by a seal packing 10 on the outer periphery of the cover 9.

A male screw 8c is formed on the side peripheral surface of the lower plate 8 of the lid 6, and this screws into a female screw 5a formed on the inner peripheral surface of the shoulder member 5. A recessed outlet 8d is formed on the lower center surface of the lower plate 8, and is opened as the valve body 11 moves downward to form a liquid path.
A liquid injection pipe 12 integrally provided in front of the liquid injection port 13 and a liquid injection port 13 formed by projecting a part of the shoulder member 5 forward in a beak shape.
connected sequentially. A flap valve 19 for opening and closing the liquid inlet 13 is provided on the upper part of the liquid inlet 13 and is pivoted by a shaft 25. A liquid inlet guide 14 is provided below the mounting part of the flap valve 19. Liquid port 1
The liquid content passing through 3 is smoothly injected by the liquid injection guide 14 without being affected by the attachment of the flap valve 19.

The upper plate 7 of the lid 6 has a guide cylinder 16 at its center for guiding the crown button 15, and has a cylindrical part 18 at the rear thereof for forming a steam venting intake passage 17, which will be described later. A crown button 15 is disposed within the guide tube 16 so as to be movable up and down but not rotatable, and an actuating tube 20 is also disposed within this button 15 so as to be movable up and down but not rotatable. Further, the valve stem portion 11b of the valve body 11 is attached to the operating cylinder 20 using screws 21. The valve stem portion 11b is connected to the outlet 8b of the lower plate 8.
It passes through a hole 8e provided in the center of the section. An annular gasket 22 is attached to the peripheral edge of the lower surface of the valve body 11a, and this portion opens and closes the outlet 8d.

The actuating cylinder 20 is urged upward by the urging spring 23, and the crown button 15 and the vertical movement position holding mechanism 41
When the crown button 15 is repeatedly pressed, the position holding mechanism 41 repeatedly holds the lower position and the upper position in sequence, and the actuating cylinder 20 and the valve body The main body portion 11a is configured to sequentially and alternately stop at the open position (the upper stop position shown in FIG. 1) or the open position (the lower stop position shown by the imaginary line in FIG. 1) and maintain that state. There is.

At the front of the upper surface of the lower plate 8, there is an upward slope 2 at the rear.
4a, a slider 24 is attached to the operating cylinder 20 and the flap valve 19, and the upper plate 7 and the lower plate 8
It is placed in front of the space. In this embodiment, the lower end of the operating barrel 20 pushes the slope 24a of the slider 24 as the crown button 15 is pressed (lower stop position).
The slider 24 projects forward from the hole 8f in the side surface of the lower plate 8, and its front end 24b pushes the upward passive slope 19a of the flap valve 19 and resists the spring 42 acting on the flap valve 19. and open the flap valve 19. At this time, the outlet 8d is unclosed by the valve body 11a, so when the container 4 is tilted by holding the handle 33 in this state, the liquid in the inner container 2 flows from the outlet 8d into the liquid injection pipe 12. The liquid is injected to the outside through the liquid injection passage and the liquid injection port 13. Then, when the body 4 is returned to its original state and the crown button 15 is pressed again to return the actuating cylinder 20 to its original position (upper stop position), the flap valve 19 pushes back the slider 24 by the restoring force of the spring 42. automatically closes while At this time, the valve body 11a presses its seal packing 22 against the rim of the outlet 8d of the lower plate 8 to seal the outlet 8d, so that the liquid in the inner container 2 flows into the opening of the lower plate 8. It does not flow into the recessed space.

A connecting pipe 27 is connected to the cylindrical part 18 provided at the rear of the upper plate 7 of the lid 6 via a seal packing 28, and its base end cylinder 29 fits into the circumferential surface of the lower plate 8 on the side of the pin-shaped valve receiving part 30. be done. A water stop valve 31 is accommodated in the valve receiving part 30, and a steam venting intake passage 17 is formed from there in the upper connecting pipe 27 and the cylindrical part 18. This steam venting intake passage 17 has a lower end opening into the inner container 2 through the through hole 30a of the valve receiving part 30 and an opening 9b of the metal cover 9, and an upper end opening into the inner container 2 through the opening 18a of the cylindrical part 18 of the upper plate 7. It is open to the outside. Steam generated during heat retention and boiling by the heater 1 is released to the outside by the steam venting intake passage 17, so that the pressure inside the inner container 2 does not rise abnormally. In addition, when the container body 4 is tilted to pour out the liquid content, the upper space created in the inner container 2 is communicated with the outside through a steam release intake passage 17, so as the liquid content flows out, outside air flows in through the passage 17. Inner container 2
This prevents negative pressure inside and allows the liquid to be poured smoothly.

Note that if the container body 4 is tilted and poured all at once, or if the container body 4 is accidentally tipped over, the water stop valve 31 moves upward due to the outflow pressure of the liquid inside and closes the through hole 32 of the joint pipe 27. Therefore, the content liquid is vented through the intake passage 1.
It does not leak out from the lid 6 through the lid 6.
Further, the water stop valve 31 is made of synthetic resin and is lightweight, and has a good closing response when the liquid inside is about to flow out.

Since the steam venting intake passage 17 does not communicate with the inside of the lid 6, it is possible to prevent outflowing steam from entering the inside of the lid 6, and to draw outside air into the container body 4 when pouring liquid. However, it is also possible to avoid sucking the air inside the lid 6, where dust and the like are likely to be mixed therein.

Furthermore, the water stop valve 31 is seated on the inclined surface 30b on the valve receiving portion 30 that does not block the steam venting intake passage 17, and is held in a position where the through hole 32 is opened.

Then, when pouring the liquid, the container body 4 is tilted sharply, and the liquid tends to be biased toward the lid 6, causing the lid 6 to tilt.
However, since the steam venting intake passage 17 is located at the rear of the lid 6, the content liquid comes into contact with the inner surface of the vapor venting intake passage 17.
can delay reaching as much as possible,
The inclined surface 30b allows the water stop valve 31 to move toward the through hole 32 side or to be moved easily depending on the inclination angle of the container body 4 when injecting the content liquid, so that the content liquid can release steam. The vent 32 can be quickly closed before it reaches the intake passage 17, and even if the liquid inside reaches the steam venting intake passage 17, it is easily moved to the side of the passage 32 by this liquid. Since it is closed, it is possible to reliably prevent the contents from flowing out.

FIG. 3 shows a modification of the present embodiment, in which the shapes of the peripheral edge 33 of the valve body 11a, the opening of the lower plate 8, and the seal packing 22 interposed between the two are devised. This is intended to improve the sealing performance with 6.

In this modification, the peripheral edge 33 of the valve body body 11a
is formed into a hook-shaped flange shape in cross section, and a seal packing 22 is attached so as to wrap around the flange.
The seal packing 22 has a seal lip 22a formed on the outer periphery of the lower side that contacts the lower surface of the peripheral edge 33,
A hollow cushion seal portion 22b is formed on the upper side that contacts the upper surface of the peripheral edge portion 33 and has a shape that allows the hollow portion 34 to be maintained between the upper surface of the peripheral edge portion 33 and the upper surface of the peripheral edge portion 33. The seal lip portion 22a is in pressure contact with the inclined surface 35 of the opening portion of the lower plate 8 (seal portion A), and the hollow cushion seal portion 22b is in pressure contact with the horizontal surface 36 of the opening portion (seal portion B). The sealing performance becomes more reliable due to the function of the sealing part. In other words, when the valve body 11 is sealed, the sealing performance is maintained by the highly flexible seal part B in the vertical direction, and when the hot water storage container is tipped over or the hot water storage container is tilted to pour out the contents at once, the sealing performance is maintained. Part A has a structure that allows the sealing performance to be maintained by the outflow of the liquid inside. In addition, the base 2 on the upper side of the seal packing 22
2c is the inner circumferential side surface 37 of the opening portion due to the lateral spreading deformation characteristic due to the pressure at the seal portion B.
Since the cushion seal part 22b comes into pressure contact with the horizontal surface 36 of the lower plate 8, the base part 22c comes into pressure contact with the horizontal surface 36 of the lower plate 8, and the base part 22c comes into pressure contact with the horizontal surface 36 of the lower plate 8. Moreover, it is possible to prevent poor sealing performance due to side-to-side vibrations such as when falling down.

(Effects of the invention) According to the invention, since the water stop valve is normally seated on the valve receiving part and opens the valve port in the middle of the steam vent passage,
When the liquid inside the container is boiled or kept warm, the steam can flow out of the lid through the steam vent passage, and the pressure inside the container will not rise abnormally. Although the pressure tends to become negative, since outside air is introduced into the vessel through the steam vent passage, the pressure does not become negative and the liquid can be poured smoothly.

In particular, when injecting the liquid by tilting the container, if the container is tilted suddenly, the liquid will tend to shift toward the lid, hitting the inner surface of the lid and reaching the rear of the lid. However, since the steam vent passage is provided at the rear of the lid and located on the opposite side of the container from the liquid injection port, it is possible to delay the content liquid from reaching the steam passage as much as possible. However, the sloping surface formed on the valve receiver allows the water stop valve to move toward the valve port side or to move easily depending on the inclination angle of the container body, so the water stop valve is closed before the liquid content reaches the steam vent passage. Close the valve port as soon as possible, or even if the content liquid reaches the steam vent passage, it will be easily and quickly moved to the valve port side by the content liquid and the valve port can be closed before the content liquid flows out. This makes it possible to reliably prevent the content liquid from inadvertently flowing out through the steam vent passage when the container body is tilted and the content liquid is injected.
