Japanese Patent Laid-Open No. 9-10111 JP 2007-208580 A

  In the invention described in Patent Document 2, the tea leaves are ground in a metal container accommodated in a kettle-shaped container, so that components that could not be consumed in the past can be ingested by roasting tea leaves in a ground state. Thus, the ground tea leaves are prevented from flowing out together with the tea, so that the invention is excellent in that it can be brewed repeatedly.

  However, the metal container has a complicated structure in which a plurality of convex blades are formed on the bottom surface and a wall surface rising from the bottom surface, and a mesh filter that allows water to permeate to the outside is provided at a plurality of locations. The process of forming a large number of convex blades inside the container and the process of separately providing a mesh filter at a plurality of locations are required due to the protrusion, and there is a problem that the manufacturing cost increases.

  In addition, since the metal container has a bottom, it is difficult to remove the tea leaves from the bottom when washing after use. In addition, the tea leaves are easily entangled with the many convex blades protruding inside the container. There was also a problem that it was difficult to remove this. In this case, since a large number of convex blades protrude from the inside of the container, there is a problem that a cleaning sponge cannot be used.

  This invention relates to a tea machine created in view of the above-mentioned problems. That is, the tea device of this invention includes a pot body having at least an upper surface opening, a spout, and a lid, a crushed plate formed by crushing a surface disposed on the inner bottom surface of the pot body, and a crushed plate A cylindrical filter made of a net-like cylinder that is detachably disposed so as to surround the upper surface thereof, and a rotary shaft that is installed in the cylindrical filter and has a lower end that is close to or slidably contacts the crushing blade surface of the crushing plate A rotating blade rotated by the shaft, a shaft hole of a crushing plate into which the lower end of the rotating shaft of the rotating blade is rotatably inserted, and an axial hole of the lid through which the upper end of the rotating shaft of the rotating blade is rotatably inserted, It has the rotary knob attached to the upper end of the rotating shaft of the rotary blade which penetrated the cover body.

  Further, the tea machine according to claim 2 is configured in a spiral screw shape in which the lower end of the rotating blade in the tea machine is close to or slidably contacted with the crushed blade surface of the crushed plate, and the peripheral side is close to or slidably contacted with the inner peripheral wall of the cylindrical filter. It is characterized by being.

  The tea set according to claim 3 is characterized in that a hot water injection hole is opened in the lid of the tea set.

  According to a fourth aspect of the present invention, there is provided a tea set in which a crushing plate configured separately from the pot body is fixed to the inner bottom surface of the pot body.

  The tea set according to claim 5 is characterized in that in the tea set, the crushing plate is made of ceramic.

  The tea set according to claim 6 is characterized in that, in the tea set, a crushing blade surface of the crushing plate is constituted by a set of a large number of protrusions.

  The tea set according to claim 7 is characterized in that, in the tea set, the crushing blade surface of the crushing plate is constituted by a bowl-shaped rough surface.

  According to the tea set of the present invention having the above-described configuration, tea leaves can be ground in a pot for brewing tea, so that it is possible to ingest components of tea leaves that could not be ingested conventionally.

  Further, since the tea leaves are ground in the tube filter, the ground tea leaves do not flow out together with the decocted tea, and the tea can be roasted repeatedly as it is. In this case, the tea leaves are roasted in a ground state, so that the color, taste, and aroma are not lost even if the tea leaves are repeatedly roasted. According to the experiment of the inventor of the present application, it has been confirmed that the color, taste, and aroma that are the same as those of the first decoction can be enjoyed until the tenth decoction.

  In addition, since the tea leaves are brewed in a ground state, the tea can be brewed not only with hot water but also with cold water.

  On the other hand, instead of the complicated structure as in the prior art, the tea leaves are crushed by a crushing plate whose surface is crushed and formed into a blade surface, and a cylindrical filter that is detachably arranged so as to surround the upper surface. Since it is a simple structure that constitutes a grinding container, the production cost can be reduced.

  In the above case, the lower end of the cylindrical filter is closed by a crushing plate in the pot, but when it is removed from the pot, it becomes a cylindrical shape with an open top and bottom. Sponge can also be used, which has the effect of easily removing tea leaves.

  Further, as in the invention described in claim 2, when the rotating blade is formed in a spiral screw shape in which the lower end is close to or slid in contact with the crushed blade surface of the plate and the peripheral side is close to or slid in contact with the inner wall of the cylindrical filter By rotating the rotating blade in the direction opposite to the direction of grinding tea, the tea leaves are lifted upward by the screw, so that the tea leaves can be easily discarded.

  Moreover, when the hot water injection hole is opened in the lid as in the device described in claim 3, there is an effect that hot water can be added without opening the lid.

  Moreover, when the crushing plate comprised separately from the pot main body is fixed to the inner bottom surface of the pot main body as in the invention described in claim 4, the pot itself does not require any special processing, so that the manufacture is easy. It becomes. In this case, since the pot body and the crushing plate can be made of different materials, for example, the pot body can be made of soft ceramics, and the crushing plate can be made of hard ceramic as described in claim 5, This has the effect of expanding the choice of pot material.

Good. When it is configured separately, the pot body 1 and the crushing plate 20 can be made of different materials. Even if the pot body is a brittle and soft material such as pottery, the crushing plate 20 is made of, for example, ceramic. By making it hard and rich in wear resistance, it is possible to make a tea set that can exhibit the effect of this device.

  The surface of the crushing plate 20 is processed into a crushing blade surface for grinding tea leaves with the rotary blade 30. In this embodiment, a set of a large number of protrusions is used as the crushing blade surface. However, the shape is not limited as long as the tea leaf can be ground, and for example, the crushing blade surface may be formed of a cocoon-shaped rough surface.

  Reference numeral 22 in the drawing denotes a cylindrical filter that is detachably disposed so as to surround the upper surface of the crushing plate 20. The cylindrical filter 22 is composed of a net-like cylinder. In this embodiment, the cylindrical filter 22 is constituted by a metal net having reinforcing rings 22A and 22B arranged on the upper and lower sides.

  A water-permeable container for grinding tea leaves is constituted by the cylinder filter 22 and the crushing plate 20 closing the lower end thereof, and a rotating blade 30 for crushing the tea leaves in combination with the crushing plate is provided in the container. Is done. The rotating blade 30 is rotatably inserted into a shaft hole 21 having a lower end drilled in the crushing plate 20, and is rotatably inserted into a shaft hole 11 formed in a lid 10, which will be described later. The blade body 31 is provided on the peripheral side of the rotating shaft 32. In this embodiment, the blade body 31 is configured in a spiral screw shape whose lower end is close to or slid in contact with the crushed blade surface of the crushed plate 20 and whose peripheral side is close to or slid in contact with the inner peripheral wall of the cylindrical filter 22. The shape is not limited as long as it has a function of grinding tea leaves in combination with at least a crushed plate.

  Reference numeral 10 in the figure denotes a lid. The lid 10 covers the pot body by engaging the engaging step provided on the lower side with the engaging step provided on the pot body 1, and rotates the rotary blade 30 through the shaft hole 11. It has a function of supporting the upper end of the shaft 32. In the figure, reference numeral 33 denotes a rotary knob attached to the upper end of the rotary shaft 32 of the rotary blade 30 penetrating the lid body 10. In this embodiment, a hot water injection hole 12 is opened in the lid 10.

  In the tea set of the embodiment of the present invention having the above-described configuration, a tea leaf is put in the tube filter 22 in a state where the tube filter 22 is externally fitted to the crushing plate 20 in the pot body 1 and the rotary blade 30 is set therein.
