Description

[Detailed description of the invention] (a) Field of the invention The present invention relates to the structure of the spouting part of liquid containers such as air pots and electric pots.

(b) Prior art and its problems Conventionally, in many general air pots, an inner stopper, in which a water lift pipe and a water injection pipe are integrally provided, is arranged between an air pump and an inner bottle. However, with this method, it is complicated to remove the inner stopper each time when discarding the remaining hot water in the medium bottle or filling hot water into the medium bottle, so a water pump is connected to the bottom of the container, and this water pump A water filling pipe is connected to the upper end of the container, and the water pumping pipe and the water filling pipe are integrally attached to the container body.

This type of liquid container requires a safety valve in the water injection pipe to prevent liquid leakage when it falls over.
Therefore, the water injection pipe has no choice but to be made of resin. However, since the water injection pipe is attached to the container body, there is a drawback that even if the water injection pipe is thermally deteriorated by hot water, the water injection pipe cannot be easily replaced.

In addition, in Japanese Utility Model Application Publication No. 57-30138, a safety valve is provided in the water injection pipe to form a spouting unit, the lower end is connected to the bottom of the container, and the upper end of the water pumping pipe arranged along the container body is connected to the water injection pipe. A device in which the projecting unit is detachably attached from above has been proposed.

However, in this case, the spout is located upward, making it difficult to pour the liquid. On the other hand, if the spout unit is connected to the pumping pipe at a low position, a problem arises in that there is a risk of natural outflow due to the siphon principle.

(c) Purpose of the invention The present invention was made in view of the above-mentioned drawbacks of the conventional technology.The purpose of the invention is to provide a liquid container that is easy to replace, which is a consumable part, such as a water injection pipe, that is easy to handle, and that does not cause spontaneous outflow. The purpose of this invention is to provide a spout structure.

(d) Structure of the device In order to achieve the above object, the structure of the spouting part of the liquid container in the present invention includes a lift pipe that guides the liquid inside the medium container upward and a water filler pipe that guides the liquid outward. a connecting part that is detachable from the upper side of the container body, and the water injection pipe is detachably connected to the water pumping pipe from the side of the container body, and a valve chamber that communicates almost horizontally with the connecting part and has a built-in safety valve. and a spout unit consisting of a spout cover, a water inlet having a slit extending upward from the valve chamber and then downward, and extending from the spout to a height near the upper end of the medium container. It is something.

(E) Description of Embodiments FIG. 1 shows an example in which the present invention is applied to an electric air pot.A resin annular shoulder body 2 is fixed to the upper end of a container body 1. A metal middle container 4 is held inside the part via a packing 3. An electric heater (not shown) is attached to the lower outer periphery of the inner container 4.

A spout unit 5 is detachably attached to the front end of the shoulder body 2. This pouring unit 5 is
As shown in FIGS. 2 and 3, a unit body 6 made of synthetic resin is provided, and one end of the unit body 6 is removably connected to an L-shaped connecting tube 2a attached to the front end of the shoulder body 2. A connecting portion 7 is formed, a valve chamber 8 housing a safety valve 9 that shuts off water in the event of a fall is provided at the center, and a spout cover portion 10 is integrally molded at the other end. The valve chamber 8 is provided with a mortar-shaped valve seat 11 on which the safety valve 9 is placed, and notches 12 are provided on both sides of the valve seat 11.
is formed. A valve lid 1 is provided on the upper surface of the valve chamber 8.
3 is attached to the valve cover 13, and a cylindrical valve opening 14 is formed in the valve cover 13. Reference numeral 15 denotes a water injection part made of synthetic resin, one end of which is fitted into the valve port 14 of the valve chamber 13 from above, the central part gradually slopes downward as it approaches the front, and the other end is fitted with a water injection part. It has a spout 16, and inside the spout 16 there is a vertical slit 1.
7 is formed. On the other hand, 18 is a lift pipe whose one end is connected to the bottom of the medium container 4, and the other end is erected along the outer surface of the medium container 4 and connected to the connection tube 2a attached to the front end of the shoulder body 2. It is connected.

As mentioned above, the reason why the mortar-shaped valve seat 11 is provided in the valve chamber 8 is that the hot water flowing from the water pump 18 through the connecting part 7 directly hits the safety valve 9 and lifts the safety valve, causing the valve port 14 to close. This is to ensure that there will be no problems when it is closed. In this case, the hot water hits the outer surface of the mortar-shaped valve seat 11 and is distributed to the left and right, and flows upward from the valve port 14 through the notch 12 as shown in FIG. In addition, the spout 1 of the water injection part 15
The reason why the slit 17 is provided inside the hot water tank 6 is to prevent the hot water from mixing with gas and liquid and causing a scattering phenomenon when the remaining hot water is low, or to prevent the hot water from naturally flowing out due to the siphon principle. Therefore, the upper end position of the slit 17 is above the water level line when the medium container 4 is full of water. Note that since the hot water coming out of the spout 16 hits the spout cover 10 and is further rectified, splashing is completely prevented.

A hinge support portion 19 is integrally provided at the rear end portion of the shoulder body 11, and a lid body 21 is provided so as to be openable and closable via a support shaft 20 inserted through the hinge support portion 19.

As shown in FIG. 4, the front end of the lid body 21 has two holes located on both sides of the spout unit 5.
The hook members 22 are provided independently. This hook member 22 is rotatably attached to the inside of the lid body 21 by its shaft portion 23, and is biased by a torsion spring 26 so that the pressing portion 24 protrudes to the outer surface of the lid body 21. . Hook member 2
The second hook pawl 25 is constantly engaged with an engaging pawl 27 protruding from the shoulder body 2 by a torsion spring 26, and the lid body 21 is held in a closed state. Then, the lid body 21 can be opened by simultaneously pressing the pressing portions 24 of the hook members 22 on both sides to release the hook claws 25 from the engaging claws 27. By providing the two hook members 22 independently on both sides of the lid 21 as described above, the space between them can be effectively used to accommodate the spout unit 5.

An air pump 28 is housed inside the lid 21, and a pusher 29 for compressing the air pump 28 projects from the top surface of the lid 21. A metal inner cover 31 having a ventilation hole 32 for sending pressurized air from the air pump 28 into the inner container 4 is fitted to the bottom plate 30 of the cover body 21. The annular packing 33 is crimped onto the upper end surface of the middle container 4.

In the electric air pot configured as described above, when the air pump 28 is compressed, pressurized air flows from the air pump 28 to the inner container 4 through the ventilation hole 32 of the inner lid 31.
The hot water in the medium container 4 is poured out via the water lift pipe 18 and the spout unit 5 by air pressure.

By the way, since the spout unit 5 is made of synthetic resin, it will deteriorate due to heat if hot water is applied to it for a long time. In the present invention, if the entire spout unit 5 is pulled out with the lid body 21 open, the connecting portion 7 can be pulled out from the water pump 18 and easily removed, so the spout unit 5 can be easily replaced. It's easy.

(f) Effect of the device As described above, according to the present invention, the water injection pipe is made into a spouting unit consisting of a connecting part, a valve chamber, and a water injection part, and this entire unit is connected to the water pumping pipe from both sides of the container body side. Since it is made removable, even if the spout unit deteriorates due to heat, it can be easily replaced. In addition, the spout unit has a connecting part, valve chamber, and water injection part that are integrated and compactly constructed, making it easy to handle and making it possible to stock up on spout units, reducing manufacturing costs. can be reduced.

Furthermore, since the spout unit is attached from both sides of the container body, the spout can be placed low, making it easier to pour liquid, and since the spout has a slit that extends to near the top of the inner container, natural outflow will not occur. In addition, since the slit is covered with the spout cover, the hot water coming out of the spout is rectified and does not scatter.
