Description

  The present invention relates to an adapter technology that is used by being inserted into a pouring spout of a kettle for pouring. The present invention relates to a technology of an air intake type adapter that guides hot water to be poured.

  In order to brew delicious koji, it generally begins with the selection of koji beans, and how to roast, how to grind, and how to brew is a problem. There are many people who are particular about how to grind and how to brew, because they often purchase roasted coffee beans in ordinary households. As for how to brew, slowly pour hot water over the ground coffee beans and steam the coffee beans to inflate the beans, extract the extract of the coffee beans, and then write the letter slowly so that the hot water is placed gently It is said that it is appropriate to pour into A kettle dedicated to firewood that allows such pouring of hot water is manufactured and sold.

  However, such techniques may have technology, and it is surprising to pour hot water in a thin and slow and constant amount so that hot water does not blow out from the spout or give off a bitter taste or miscellaneous taste. It is difficult. In addition, it is said that if the hot water contains a lot of air, the mouth feel becomes mellow, but skilled techniques are required to execute these depending on the pouring method.

There are two types of kettle pouring spouts, the crane mouth type and the narrow mouth type. The narrow mouth type is suitable for kettles that contain straw, as it can keep pouring hot water while maintaining a certain thinness. It can be said. However, it is not suitable for pouring thickly, and it is said that it lacks versatility. On the other hand, the Tsuruguchi type has the advantage that it can be poured thickly and is highly versatile because it is thinly drip-extracted. On the other hand, there is a disadvantage that it is necessary to get used to controlling. Accordingly, there is a need for a method for anyone to easily and stably pour hot water from a kettle.

Therefore, various technical proposals have been conventionally made. For example, a technique in which the name of the invention is a “coffee drip pot” is disclosed (see Patent Document 1).
Specifically, an object is to “provide a coffee drip pot capable of stably performing hot water pouring operation on coffee powder” and a solution means that “the coffee drip pot is made of metal and has a substantially cylindrical shape. The container main body, a metallic thin tubular pouring tube attached to the lower part of the container main body, a lid attached to the upper opening of the container main body, and a gripping part attached to the side of the container main body. The dispensing tube is extended so as to rise upward from the attachment position to the container main body, and a bellows portion which is a variable portion is formed at an upper position of the container main body. The spout is open at the tip of the spout, and the entire spout is formed into a narrow tube with almost the same diameter, and can be curved and deformed in all directions at the bellows, allowing the spout to be positioned freely Adjust to It is intended.
However, since the technique described in Patent Document 1 is a dedicated product having a variable portion that can bend and deform the extraction port of the pot, the existing pot cannot be used, and thus the problem of the present invention is solved. Not in.

In addition, a technique in which the title of the invention is “extractor for hand drip” is disclosed (see Patent Document 2).
Specifically, “The components of coffee bean powder can be easily extracted using filter paper or a metal coffee extractor, etc., and the structure is extremely simple and easy to use. The problem is to provide an extractor for hand drip that is easy to manufacture and can be manufactured at low cost. By providing a notch on the inner bottom of the filtration part as a solution, the gap between the protruding rib and the notch becomes a liquid conduit. The coffee bean powder is slowly and intermittently dripped with the filtrate over a wide range.Furthermore, the fine powder mixed in the extract that occurs when a metal filter is used is removed by providing a sedimentation groove reservoir. It is.
However, the technique described in Patent Document 2 cannot use an existing dripper, a paper filter, or the like, nor can it take in sufficient air, and has not yet solved the problem of the present invention.

Further, a technique in which the title of the invention is “liquid supply device” is disclosed (see Patent Document 3).
Specifically, “It is an object to provide a liquid supply device that can prevent dripping of the spout without causing a poor supply of liquid such as tea liquid, and the solution is to maintain a mixture of tea leaves and hot water. A hole is provided in the vicinity of the spout of the tube portion provided in the main body. "
However, although the technique described in Patent Document 3 can prevent dripping of the pouring spout, there is no description about the configuration for rectifying or stabilizing the liquid poured from the pouring spout and solves the problem of the present invention. It has not reached.

Hereinafter, description will be given based on the drawings. However, the present invention is not limited to the shape and configuration described in the drawings, and can be changed within a range in which an effect exhibited as a creation of the technical idea of the present invention can be obtained.
FIG.

FIG. 1 is a basic configuration explanatory view for explaining the basic configuration of a kettle air intake adapter 1 according to the present invention, and FIG. 2 shows a representative embodiment of the kettle air intake adapter 1 according to the present invention. It is an Example explanatory drawing shown.
Hereinafter, each structure of the air intake adapter 1 for kettles which concerns on this invention is demonstrated.

  The linear member 10 is a long member that has flexibility and is inserted into the pouring spout to guide the hot water discharged from the pouring spout and take air into the hot water. For materials, stainless steel, copper, iron and other materials that are safe even when in contact with food. In addition, when using copper, it is desirable to give tin plating or silver plating as prescribed in the Food Sanitation Law. As shown in FIG. 2 to FIG. 5, the surface has irregularities, and as shown in FIG. 1, it is deformed into a shape corresponding to the shape of the spout as shown in FIG. To do. Moreover, the linear member 10 plays the role which reduces the cross-sectional area of a pouring spout by being inserted in the spout S, restrict | squeezes a flow volume, and enables the thin and stable discharge | release.

  The convex portion 20 is for forming continuous irregularities on the surface of the linear member 10. The surface of a rugged object affects the flow of the object surface layer, and the rougher the surface, the more disturbed the flow is, so the boundary layer is likely to transition to turbulent flow. Since the turbulent boundary layer has a larger velocity gradient than the laminar boundary layer, the frictional resistance is increased, and the turbulent boundary layer is difficult to separate from the object. The frictional resistance is the friction of the surface of the object caused by the viscosity of the fluid. The larger the area where the fluid and the object are in contact, the greater the frictional resistance, and the frictional resistance increases in proportion to the velocity gradient of the object interface (Newton's). Viscosity law). Therefore, by continuously forming the convex portion 20 on the surface of the linear member 10, the hot water flowing out from the spout S is made difficult to peel from the linear member 10, and the hot water flow path is guided and poured. In addition to exerting the effect of facilitating, the fluctuation line Y is given to the streamline, and the contact area with the air is increased, thereby exerting the effect of taking air into the poured hot water. It is also effective to perform embossing to form the convex portion 20.

  The hole 30 is for forming continuous irregularities on the surface of the linear member 10, and aims at the same effect as the convex part 20. Although it is good, the structure combined with the convex part 20 is also desirable (refer FIG.3 (d)). In particular, by increasing the contact area with the air, the effect of taking air into the poured hot water is exhibited.

  The wire 40 is a member for constituting the linear member 10, and is a material in a case where a plurality of wire materials are woven together as shown in FIG. 2 or FIG. 3 (a), for example. More specifically, it is formed by braiding so that the surface of the linear member 10 is uneven. However, the knitting method is not limited to this, and any knitting method may be used as long as the surface of the linear member 10 is uneven. In this case, it is also effective to knit loosely so that the hole 30 is intentionally generated.

  The continuous corrugated shape 50 is a shape that is formed into a corrugated shape so that the convex portions 20 appear alternately on both surfaces of the linear member 10 as in the embodiment shown in FIG.

  In the spirally twisted shape 60, as in the embodiment shown in FIG. 3B, the wire 40 is twisted in a spiral shape and discharged while guiding the flow path of the fluid discharged from the spout in the rotational direction. It is a shape to make it.

  The kettle K does not need to be a dedicated product, and may be a commercially available product. However, a kettle from which hot water jumps out with a large spout is not very suitable because the spout S is short and the amount of discharged hot water is difficult to adjust.

The spout S is a hot water discharge port protruding upward from the bottom of the container, and serves as an insertion portion for inserting the kettle air intake adapter 1 according to the present invention. There are so-called crane mouth type and narrow mouth type in the kettle for firewood generally marketed. The Tsuruguchi type can discharge a large amount of hot water from a small amount, but it requires a technique for handling, and the narrow mouth type is suitable for hand dripping of cocoons, but has a problem that it lacks versatility due to its low discharge amount. doing.
FIG.

  FIG. 3 is an explanatory diagram of an example illustrating the shape of the linear member 10 according to the present invention. 3 (a) shows an embodiment similar to FIG. 2 in which a plurality of wires are knitted, FIG. 3 (b) shows an embodiment of a spirally twisted shape, and FIG. An example of a long and flat corrugated shape is shown, and FIG. 3D shows an example in which irregularities are provided on a long flat plate.

  The embodiment in FIG. 3A is the most suitable configuration including the embodiments described later. The left side of FIG. 3A is a left side view, the upper right is a front view, and the lower right is a side view. A corrugated arrow line is shown above the side view, and this shows a streamline of hot water flowing along the linear member 10 having concavities and convexities on the surface. Is shown. The boundary layer near the surface where the flow is rough is likely to transition to turbulent flow, and the turbulent boundary layer has a larger velocity gradient than the laminar boundary layer, so that the frictional resistance is increased and the linear member 10 is difficult to peel off. Become. Therefore, the flow path R is guided along the shape of the linear member 10.

  In the embodiment shown in FIG. 3B, a plurality of wire rods 40 are wound around the wire rod 40 serving as a core member while being spirally twisted. The reason why such a core material is used is that it is difficult to be plastically deformed due to elasticity when it is set as a side line, so that the deformed shape corresponding to the shape of the spout S of the kettle K can be easily held.

  In the embodiment in FIG. 3C, the surface of a long and flat wire is formed in a continuous wave shape. Moreover, when the hole part 30 is provided, fluid resistance becomes large and the function to take in air improves. Moreover, it becomes easy to form in arch form from the spout S by making it into a wave type.

In the embodiment shown in FIG. 3 (d), long and flat protrusions that are continuous with the surface of the flat wire are formed on both sides. Moreover, when the hole part 30 is provided, fluid resistance becomes large and the function to take in air improves. In addition, although it has shown by the structure which provided the convex part in the open wire 40 in drawing, the structure which provides a convex part and a hole in the surface of the wire 40 whose cross section is round shape is also suitable.
FIG.

  FIG. 4 is an explanatory diagram of a use state using the kettle air intake adapter 1 according to the present invention. FIG. 4 (a) shows the hot water discharge state in the state where the spout S is the crane mouth type and the kettle air intake adapter 1 according to the present invention is not used, and FIG. 4 (b) shows the spout S. Shows a state in which hot water is discharged in a state using the air intake adapter 1 for a kettle according to the present invention, and FIG. 4 (c) shows a kettle according to the present invention in which the spout S is a narrow mouth type. FIG. 4 (d) shows a state in which the pouring spout S is a narrow mouth type and the air intake adapter 1 for a kettle according to the present invention is used. The hot water discharge state is shown respectively.

  As shown in FIG. 4 (a), the crane mouth type spout S is discharged at the same angle and with the highest flow rate. This is considered to be simply because the cross-sectional area of the spout S is the largest (According to Torrichelli's theorem, the flow velocity is determined by the difference between the outlet height of the spout S and the liquid level in the container (rate = 2 × square root of weight acceleration), the flow rate is determined by the product of flow velocity and cross-sectional area).

  FIG. 4B shows that the cross-sectional area of the spout S is reduced by inserting the kettle air intake adapter 1 in the crane mouth type spout S according to the present invention, which is compared with FIG. 4B. In this state, the flow rate is suppressed and air is stably taken in and released. It should be noted that even the Tsuruguchi type, which is difficult to adjust the flow rate, can be adjusted from a small amount of drip discharge to a large amount of large discharge. Therefore, it can be said that the defects of the Tsuruguchi type are improved.

  As shown in FIG. 4 (c), the spout S shows the discharge state in the narrow-type kettle K, and in the narrow-type spout S, compared with the crane mouth type shown in FIG. 4 (a). It can be seen that the amount of hot water is small even at the same angle. Moreover, the fluctuation Y is large and can be said to be thin and stable.

  FIG. 4 (d) shows that the cross-sectional area of the spout S is reduced most by the insertion of the kettle air intake adapter 1 according to the present invention into the narrow spout S, and another embodiment (FIG. 4 (a) to FIG. 4 (c), it can be confirmed that the amount of hot water is the smallest and that a fine fluctuation Y is given to the streamline.

  FIG. 5 is an example explanatory view showing another embodiment of the kettle air intake adapter 1 according to the present invention, in which the linear member 10 is inserted into the pouring spout S of the kettle K and protrudes from the pouring spout S. The example of a structure which let the inside of the wire 40 pass the resistor 70 with which the through hole was vacated is shown. 5A shows the case where the resistor 70 passing through the center of the substantially spherical shape is arranged on the convex portion 20, and FIG. 5B shows the case where the resistor 70 having the through hole is arranged on the hole portion 30. 5 (c) shows a case where the projection 70 is arranged in a configuration in which the convex portion is arranged, and FIG. The case where it arrange | positions to 20 is illustrated, respectively.

  As shown in FIGS. 5 (a) to 5 (d), the resistor 70 has a through hole that passes through the vicinity of the center, and is used by inserting the wire 40 through the through hole, thereby increasing the fluid resistance. Thus, the frictional force due to peeling is increased and the flow path R is guided. In addition, although the external shape of the resistor 70 is only shown as a substantially spherical body in the drawings, the shape, material, or size of the resistor 70 is not particularly limited. However, it is desirable to use a material that is harmless to the human body because it touches the beverage. For example, it may have a diameter of about 1 mm to 6 mm using a metal such as stainless steel, titanium, or copper, glass, or sintered material. desirable. When such a configuration is adopted, the resistor 70 is swung by the vibration of the fluid, and a production effect that a pleasant tone color is generated and a decorative effect such as an aesthetic appearance are also exhibited.

According to the air intake adapter 1 for a kettle according to the present invention, it can be used simply by attaching it to an existing kettle or pot, and it can provide a mellow coffee cake that has taken in air, so a coffee shop, coffee shop, convenience store, etc. Since it can be used in many stores and ordinary households, the industrial applicability is considered high.
