Description

[Detailed Description of the Invention] This invention relates to an electric pot that discharges the contents under pressure.

Conventionally, this type of electric pot was developed in 1982.
Publication No. 143128, Publication No. 56-50331, Publication No. 1983
Many proposals have been made in JP-A No. 55-128632, JP-A-56-11726, JP-A-56-14533, JP-A-55-107841, etc. They pressurize the liquid content with an air pump installed on the lid at the top of the container, and the liquid that is about to be pushed out under this pressurization is passed through a spouting tube extending from the inside of the container to the outside of the container. It is derived to the outside by.

However, since the dispensing tube is long and thin, the pressurized liquid flows out with great force, and when the liquid is finally poured out, pressurized air is mixed in and ejected, causing a splash phenomenon in which the liquid splashes around. It is dangerous to use as it may occur.

Furthermore, as disclosed in Japanese Utility Model Application Publication No. 56-85640, a local passage expansion section is provided in the middle of the dispensing pipe, and this passage expansion section temporarily widens the dispensing content. Although it may be possible to attenuate its force by letting it flow into the chamber, this may actually increase the internal pressure, which may not be released and affect subsequent outflow, causing the contents to flow out forcefully. Furthermore, it is not possible to completely prevent splashes from occurring. Moreover, the passageway extension is provided in a narrow plug, and in order to provide a sufficient size, the plug and the outer lid structure are enlarged.

The purpose of this invention is to provide a pressurized liquid dispensing electric pot that can eliminate the drawbacks of the conventional pot. , an air vent provided through the shoulder of the container body, forming a local passage expansion part for preventing splash at least in the part of the dispensing conduit passing through the shoulder part of the vessel body, and communicating with the outside through this passage expansion part; It is characterized by having holes.

To explain the embodiment shown in FIG.
The container body 1 is formed by accommodating a metal inner container opening 3 in a metal outer case 2, and joining these together with a synthetic resin shoulder portion 4 at the upper end of the container body 1 using screws 5 or the like. 6
is the bottom plate fixed with screws 7. A heater 8 is wound around the outer periphery of the bottom of the inner container 3, and the heater 8 is controlled to be energized so as to keep the content liquid warm or boil water and keep it warm. The shoulder 4 forms a liquid supply/discharge port 9 of the container body 1 that communicates with the inner container 3, and the supply/discharge port 9 is opened and closed by a lid 11 that is screwed 10 thereto. . The lid body 11 is a manual bellows pump 12
is equipped with a press plate 1 facing the top surface of the lid body 11.
When the pump 12 is pressed by 3, the lid 11
Pressurized air is directly supplied into the inner container 3 from the discharge port 12a of the pump 12 facing the bottom surface through the supply/discharge port 9,
The liquid inside is pressurized. 12b is an intake port of the pump 12, 12c is an intake port valve, and 14 is a pump restoring spring.

A spouting conduit 15 that guides to the outside the content liquid that is pressurized and forced out by air supplied into the inner container 3 is provided through the inside of the shoulder 4, and is provided through the inside of the shoulder 4. A local passage expansion part 16 for splash prevention is formed in the area. The passage expansion part 16 is formed inside the shoulder part 4 next to the supply/discharge port 9, and the passage expansion part 16 is formed inside the shoulder part 4 next to the supply and discharge port 9.
consists of an inner conduit 15a and an outer conduit 15b bordering on the passage expansion part 16. inner pipe line 15a,
The outer conduit 15b is connected via the passage expansion part 16. The inner pipe line 15a has an upper end 15a ₁ connected to the bottom of the passage expansion part 16 and suspended between the outer case 2 and the inner container 3, and a lower end 15a ₂ connected to the bottom of the inner container 3. . In addition, the inner pipe line 15
The vertical part a is made into a transparent tube _15a3 which also serves as a liquid quantity display tube.

The outer conduit 15b is slidably fitted into the passage expansion part 16 so that it can expand and contract on the horizontal line, and by expanding and contracting, changes the degree of protrusion of the distal end spout 17 from the outer surface of the container body 1, and also When not in use, it is kept in the least protruding state. Further, the outer pipe line 15b is configured to cut off communication with the inner pipe line 15a when it is in the most contracted virtual line state, and to communicate with the inner pipe line 15a when it is pulled out to a certain degree of expansion or more. In other words, the outer pipe line 1
As 5b expands and contracts depending on whether it is used or not, the spouting pipe 15 is automatically opened and closed. In particular, the closed state of the spouting pipe 15 when not in use improves heat retention and provides a water-stopping function that prevents the contents from flowing out through the spouting pipe 15 when the container 1 falls over.

A transparent plate 18 is attached to the top surface of the passage expanding portion 16, and the pouring conduit 15 is attached as the outer conduit 15b expands and contracts.
It is possible to externally observe the content liquid dispensing status in the open/closed state of the drain pipe 15 and in the open state of the dispensing pipe 15. Between the transparent plate 18 and the shoulder portion 4, an air vent hole 19 is formed from the passage expansion portion 16 to the outside. The air vent hole 19 allows pressurized air mixed in the liquid to be pushed out through the spouting pipe line 15 to escape to the outside, so that the spouted liquid flows through the passage expansion section 16.
In combination with the rapid speed reduction and loss of momentum caused by the widening of the passageway in the spout, it is possible to prevent the so-called splash phenomenon in which the spouted content jets out from the spout 17 and scatters around.

The exterior case 2 has a liquid level display window 2 that allows the inner pipe line 15a, which also serves as a liquid level display tube, to be observed from the outside.
0 is established. 21 is a transparent plate attached to the window 20. 22 is a seal packing between the lid body 11 and the supply/discharge port 9; 23 is each pipe line 15a, 15;
This is the blocking seal packing between b.

In FIG. 2, the outer conduit 15a is suspended directly into the inner container 3 from the shoulder portion 4, and a liquid amount display tube 24 is separately provided. The rest is the same as the embodiment shown in FIG.

The embodiment shown in FIG.
The liquid supply/discharge port 9 formed by the shoulder portion 4 is opened and closed by the lid body 32 which has been closed.
A lock lever 34 is pivotally supported at the free end of the lid 32 and elastically engages with a locking portion 33 of a portion of the shoulder 4 to hold the lid 32 in a closed state. The vessel 1 is
A vacuum insulation space 37 is provided between an outer container 35 and an inner container 36 made of a metal with low thermal conductivity such as stainless steel to form a vacuum double container made of metal. The bottom to which the lower end of the inner pipe line 15a of the container body 1 is connected is a single bottom part 38 in which no heat insulating space 37 is formed, and the connection structure of the lower end of the inner pipe line 15a is designed so that the formation of the vacuum heat insulating space 37 is not difficult. There is. The vacuum insulation space 37 is formed by the outer container 35.
The joint 43 between the inner container 36 and the vacuum insulation space 37 can be formed by brazing or the like in the vacuum space. The outer pipe line 15a is vertically installed on the outside of the outer container 35 and also serves as a liquid level display tube. It is covered by a cover 40 provided on the outer surface. 41 is a liquid volume display window of the cover 40, and 44 is a transparent plate of the liquid volume display window 41. The rest is the same as the embodiment shown in FIG. 1 above.

FIG. 4 shows that between the shoulder portion 4 and the outer conduit 15b,
A protrusion 51 and a recess 52 are formed that elastically engage with each other when the outer conduit 15b is in the most contracted state of non-use, thereby stabilizing the closing function of the dispensing conduit 15 by the outer conduit 15b in the non-use state, The outer conduit 15b does not move even if there is a shock when the container 1 falls over.
Water stoppage is ensured by closing the pouring pipe 15. Various other types of elastic locking structures as described above for the outer conduit 15b can be adopted.

According to this invention, a spout pipe communicating with the inside and outside of the container body is provided via the inside of the shoulder of the container body, and at least a portion of the spout pipe passing through the shoulder is provided with a local passage expansion part to prevent splashing. Therefore, by using the dead space created by the shoulders, it is possible to form a sufficiently large passage expansion part without increasing the size or complication of the vessel body or its surrounding ancillary structures, and this passage expansion part can be By providing an air vent hole that communicates with the outside, the force of the poured liquid is reliably attenuated by the sufficiently large passage expansion section, and the resulting increase in liquid pressure and pouring pressure are released through the air vent hole. Furthermore, since trapped air can be released, the liquid content can be poured out in a quiet and stable state at all times, ensuring safety in use.
