Description

[Detailed description of the invention] (Industrial application field) The present invention relates to hot water storage containers such as electric pots, etc., and in particular, the invention relates to hot water storage containers such as electric pots, etc. The present invention relates to a hot water storage container equipped with a lid that opens and closes.

(Prior Art) Steam is constantly generated in a container storing hot water. This steam condenses on the inner end surface of the lid facing into the container body. This condensed water does not drip until it condenses to a large extent, and even if it drips, some of it remains. Therefore, when the lid is opened, a large amount of dew condensation water adheres to the inner end surface of the lid. On the other hand, the lid that is opened is rotated upward around the hinge connection portion and rises up, and the slope of the inner end surface of the lid becomes steeper. As the slope of the inner end surface becomes steeper, the adhering condensed water begins to run down the inner end surface of the lid, and some of it may even flow out around the outside of the container.

Utility Model Publication No. 1-14282 discloses a hot water storage container improved to avoid this problem. In this case, the inner end surface of the lid facing inside the container has a slope that slopes downward toward the hinge connection side when the lid is closed, and a downward convex portion is formed on at least the outer periphery of the inner end surface on the hinge connection side. ing. When the inner end surface is inclined, the condensed water that has condensed thereon flows down the inclined inner end surface by gravity to the lowest part and joins other condensed water, increasing the amount of condensation and making it easier to drip.
The condensed water that reaches the lowest part of the inner end face without dripping clings to the surface of the convex portion with good wettability, and is promoted to drip along the convex portion. Therefore, even when the lid is closed, the amount of condensed water remaining on the inner end surface can be halved. Moreover, when the lid is opened to a half-open state, the hinge connection side portion of the convex portion
Condensed water that has collected on the hinge connection side portion of the protrusion near the inner edge of the mouth of the container can be transmitted to the inner wall of the container.

(Problem to be solved by the invention) However, in the above conventional example, the slope of the inner end surface of the lid is not so large, and the movement of the inner end surface toward the hinge connection side when the lid is closed is not very active. The reality is that steam is constantly generated inside the container and condenses when it touches the inner end surface, so that condensed water adheres to the entire inner end surface.

For this reason, even if the condensed water on the hinge connection side of the convex portion on the outer periphery of the inner end surface moves successfully toward the container body when the lid is half-open, the lid will not remain in the half-open position and will be fully opened in an instant. Sisters,
Since the condensed water adhering to the inner end surface does not flow down completely and remains, it will run down the lid when the lid is fully open. At this time, the hinge connection side portion of the convex portion on the outer periphery of the inner end surface moves to the outside of the mouth of the container, so that the water that drips down flows around the outside of the container.

Therefore, the present invention provides a hot water storage container that can solve the above-mentioned conventional problems by mainly modifying the lid side to restrict the flow of condensed water that tends to drip down when the lid is fully opened. This is the issue.

(Means for solving the problem) In order to solve the above problems, the present invention
A lid that opens and closes the mouth of the container by rotating around a hinge connection to one side of the mouth, and a lid that opens and closes the mouth of the container by rotating around a hinge connection part to one side of the mouth, and a lid that opens and closes the mouth of the container by rotating around a hinge connection part to one side of the mouth, and a lid that opens and closes at least the outer circumference of the hinge connection side half of the surface of the lid facing the inside of the container downward. A protruding guide ridge is provided, and this guide ridge forms a flow groove divided by the hinge connection side portion, and the flow groove is located above the mouth of the vessel when the lid is in a fully open position. It is characterized by the following structure.

Further, it is preferable that the lid is hingedly connected to the container body above the flow groove position in the closed state, and the guide ridge has a small downward ridge on the periphery of the outer periphery of the lid. is also suitable.

(Function) Steam generated inside the container condenses on the surface of the lid that covers the mouth of the container that faces the inside of the container. When they get up, they rotate along the sloping surface and gather at the hinge connection side. At that time, the guide protrusion provided on the outer periphery of the hinge connection side half of the surface of the lid facing the inside of the container effectively guides the condensed water flowing toward the hinge connection side, and the guided condensation water is removed by the guide protrusion. The condensed water flows down into the mouth of the container from the drainage groove formed by dividing the water, and even when the lid is instantly fully opened, the drainage groove is located above the mouth of the container, allowing condensed water to flow into the mouth. Since it can be dropped reliably, it is possible to prevent condensed water from flowing out around the outside of the container.

In addition, by placing the hinge connection portion above the flow groove position when the lid is closed, the flow groove can be reliably positioned above the mouth of the vessel when the lid is fully opened. can.

In addition, if a small downward protrusion is formed on the periphery of the guide protrusion on the outer circumferential side of the lid, the periphery of the surface of the lid facing the inside of the container where the guide protrusion is provided will have better wettability with water, and will attract fine water droplets around it. By causing the condensed water to form large droplets, the condensed water is transmitted down the slope and falls smoothly from the drainage groove.

(Example) The present invention will be explained below with reference to the drawings.

In the first embodiment of the present invention shown in FIGS. 1 to 3, an inner container 1 is housed and held in an outer case 2 to form a container body 3. The mouth portion 1a of the inner container 1 is connected to the upper end of the exterior body 2 by a shoulder member 4, and the outer lid 6 is opened by engaging the hinge shaft 5 of the outer lid 6 with the bearing portion 4b of the shoulder member 4. Connected so that they can be opened/closed and detached. An inner cover 7 that closes the mouth portion 1a of the inner container 1 is attached to the lower surface of the outer cover 6, and is opened and closed integrally with the outer cover 6.

A seal packing 1 is provided at the outer peripheral end of the inner lid 7 with a seal lip 18a that presses against the opening 1a when the lid is closed.
8 is fitted, and a guide protrusion 17 that projects downward is provided on the lower surface 7a facing into the inner container 1. This guide protrusion 17 is connected to the inner container 1.
Even if the steam generated inside condenses on the lower surface 7a of the inner lid 7, the condensed water is guided to the hinge connection side by utilizing the tilt caused by the rotation when the lid is opened. do the work. The guide protrusion 17 is protruded so as to swell toward the hinge connection side, and when the lid is opened as shown in FIG. There is. Therefore, the condensed water collected on the hinge connection side on the lower surface 7a by the guide protrusion 17 as described above flows down into the inner container 1 from the flow groove 19.
Since the flow groove 19 is formed below the hinge shaft 5 when the lid is closed, even when the outer lid 6 or the inner lid 7 is instantaneously fully opened, the flow groove 19 will not be located above the mouth portion 1a of the inner container 1. It is reliably positioned and can completely prevent condensed water from flowing around the outside of the container body 3. Furthermore, a downwardly directed small protrusion 20 is provided on the outer peripheral edge of the guide protrusion 17 . Providing this small protrusion 20 improves the wettability of the guide protrusion 17 with water, and by adsorbing small water droplets around the guide protrusion 20 and turning them into large water droplets, the condensed water can be smoothly removed from the inner container 1.
It is flowing inward.

A bellows pump 9 is provided inside the outer cover 6 and is pressed and operated by a top pressing plate 8 of the outer cover 6. The bellows pump 9 pumps the contents through an air supply passage 11 provided between the inner cover 7 and the bottom plate 10 of the bellows pump. Pressurized air is sent into the container 1 to pressurize the liquid inside.

An outlet path 12 for guiding the pressurized internal solution upwardly outside the inner container 1 is provided with its base end connected to the bottom of the inner container 1, and its upper end connected to a synthetic resin elbow 13. This elbow 13 is an inverted U-shaped tube 2 fixed to the back side of the beak-like part 4a of the shoulder member 4.
Connected to 3. The inverted U-shaped pipe 23 has a built-in water stop valve 14 in case of overturning. A pipe cover 15 is assembled under the beak-like part 4a of the vessel body 3, and the beak-like part 4a
and is fitted into the exterior body 2 of the vessel body 3. A liquid injection guide tube 16 is detachably attached to the bottom of the pipe cover 15 from below.

In the first embodiment, the lower surface 7a of the inner lid 7 is formed horizontally in the closed state, but it may also be formed in an inclined manner as in the second embodiment shown in FIGS. 4 and 5. good. Further, in the second embodiment, the lower surface 7a is formed to have a cup shape when viewed from below so that water droplets condensed on the lower surface 7a gather on the outer circumferential side of the lower surface 7a. A guide protrusion 17 having a narrower width than that of the first embodiment is provided at the outer peripheral end of the lower surface 7a of the inner lid 7 formed in this manner. This guide protrusion 17 is formed with a flow groove 19 that divides it, as in the first embodiment.

In the second embodiment, when the lid is in the closed state, the lower surface 7a is inclined toward the hinge connection side as described above, and the outer circumferential side is also formed to be inclined in the cup shape, so that the problem occurs within the inner container 1. Even if the steam condenses on the lower surface 7a, it travels along the inclined surface, gathers on the hinge connection side, and falls into the inner container 1 from the end of the guide protrusion 17 in the form of large water droplets. Therefore, when the lid is closed, the number of water droplets adhering to the lower surface 7a is reduced, and the amount flowing down through the flow groove 19 is also reduced. As mentioned above, since the lower surface 7a is sloped in a cup shape, the condensed water accumulated near the guide protrusion 17 is guided by the guide protrusion 17 at the same time as the lid is opened, and flows smoothly into the inner container 1. do.

In the first and second embodiments, the guide protrusion 17 is provided on the entire outer periphery of the lower surface 7a of the inner lid 7, but as shown in FIGS. 6 and 7, it is provided on the outer periphery of the hinge connection side half. You can also do that.

In the third embodiment shown in FIG. 6, the guide protrusion 17 is provided in an arc shape. As shown by the imaginary line, small protrusions 20 are provided on the outer periphery of the guide protrusions 17 to improve the wettability of the guide protrusions 17, and to adsorb fine water droplets adhering to the vicinity of the lower surface of the guide protrusions 17. It can be made easier to flow down as water droplets. Further, the small protrusion 20 is provided with a protrusion 20a toward the hinge connection side at the end of the flow groove 19 to improve water drainage. Note that the guide protrusion 17 can also be provided with a more simplified shape as in the fourth embodiment shown in FIG.

The fifth embodiment shown in FIG. 8 has a lower surface 7a of the inner lid 7.
A protrusion 21 extending toward the mouth portion 1a of the inner container 1 is provided on the end surface closest to the hinge connection side. This protrusion 21 is set to be approximately the same width as the flow groove 19 provided by dividing the guide protrusion 17, and ensures that the condensed water that is guided by the guide protrusion 17 and falls from the flow groove 19 is finally removed. It functions to guide the inside of the inner container 1.

The sixth embodiment shown in FIG.
A part of b is divided to form a condensed water receiving groove 22. Since the opening of the container body 3 can be expanded by the receiving groove 22, it is not necessary to set the bearing part 4b higher than the position of the flow groove 19 when the lid is closed, as shown in the first embodiment. , the condensed water can easily fall into the inner container 1.

(Effect of the invention) Since the invention according to claim 1 has the above-mentioned structure and operation, when the lid is raised up by rotation around the hinge connection part, the lid does not close even when the lid is instantaneously fully opened. The condensed water that tries to run down the surface facing the inside of the container is guided by the guide protrusion and collects on the hinge connection side, and then is allowed to fall reliably into the mouth of the container from the flow groove. Prevents condensed water from flowing around the outside of the body.

Further, according to the second aspect of the present invention, when the lid is fully opened, the flow groove can be reliably positioned above the mouth of the vessel.

Further, according to the invention as claimed in claim 3, the water wettability of the peripheral edge of the small protrusion improves, and by adsorbing small water droplets around the area and turning them into large water droplets, the condensed water is transmitted down the slope. It can be dropped smoothly from the flow groove.
