Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a kettle for boiling water.

[Conventional technology and its problems]

Kettles are primarily used for boiling water, but they are also used for boiling barley tea.

When using for barley tea, put water and barley tea ingredients in a kettle and boil it, or add the barley tea ingredients after the water has boiled, then put the kettle in a shallow pot, and pour tap water into the pot and let it overflow. The barley tea in the kettle is cooling down.

By the way, cooling barley tea while overflowing with water is not only inefficient, but also wastes tap water.

Therefore, the purpose of this invention is to provide a kettle that is efficient in cooling barley tea with tap water when used for boiling barley tea, and that allows the water (hot water) used for cooling barley tea to be reused without being thrown away. It's about doing.

[Means for solving the problem] In order to solve the above problem, this invention has a heat exchanger made of a vertical cylindrical spiral metal pipe suspended from the lid attached to the kettle body. Both pipe ends pass through the lid, one end of a drain pipe is rotatably connected to one end of the pipe, and a tap water hose connection part is formed at the other end of the kettle.

[Effect]

When using it for boiling barley tea, after boiling the barley tea, point the end of the drain pipe on the lid toward the receiving container on the side of the kettle, connect the tap water hose to the tap water hose connection formed on the lid, and pour tap water. By letting it flow out, the tap water passes through a heat exchanger and is received as hot water in a container on the side of the kettle.

〔Example〕

In FIG. 1, 1 is the kettle body, 2 is its spout, 3 is a handle, and 4 is a lid.

In the center of the lid 4 is a hole 6 through which a tea strainer 5 is suspended.
This hole is closed with a plug 7 with a knob.

A heat exchanger 9 made of a vertical cylindrical spiral metal pipe 8, such as stainless steel, hangs down from the bottom surface of the lid 4, and the cylindrical part of the heat exchanger 9 is concentric with the outside of the tea strainer 5. Both pipe ends a and b pass through the lid 4, and one end of a drain pipe 10 is rotatably connected to one pipe end a. Reference numeral 11 designates a drain pipe connecting cylinder part that stands up on the lid 4, 12 a packing between the drain pipe and the connecting cylinder, and 13 a cap screwed into the drain pipe connecting cylinder part for compressing the upper end of the packing 12.

A hole 14 is formed in the portion of the heat exchanger 9 where the other pipe end b passes through the lid 4, into which the tip of a tap water hose (not shown) is inserted.

The drain pipe 10 has both ends bent to one side (downward) so that the free end can be fitted into the tap water hose insertion hole 14, so that the outer edge of the hole 14 is aligned as shown in FIG. It is cut out so that the pipe end can be fitted from the side. 15 indicates the notch.

When the drain pipe 10 is stretched over the lid 4 as shown in the figure, its horizontal main portion overlaps the bottom surface of the handle 3, so that when the handle 3 is grasped, the drain pipe 10 can also be grasped. The part corresponding to the horizontal main part of the pipe 10 has a downward "U"-shaped cross section, and one end of the handle is connected to the kettle body 1 side with a hinge fitting 16 so that it can be raised and lowered freely, and the other end is a stop that stands up from the kettle body. Gold 17
It can be locked to the upper end of the. Reference numeral 18 indicates a hole formed at the upper end of the catch 17, 19 indicates a claw attached to the free end of the handle 4 and engages with the hole 18, and 20 indicates a push portion of the claw 19 for releasing the lock.

The illustrated lid 4 has a plastic molded member 22 connected to a metal substrate 21 with screws 23. 24
1 shows silicone rubber for fixing both pipe ends a and b of the heat exchanger 9.

To boil barley tea with this kettle, kettle body 1
Pour water into the tea strainer 5, put the barley tea ingredients into the tea strainer 5, close the lid, and boil the water. To cool the boiled barley tea, flip up the handle 3 as shown by the chain line in Figure 1, and connect the drain pipe 10 to the second As shown in the figure, rotate the free end so that it comes out of the kettle body, position the tip of the pipe on a water (hot water) receiving container (not shown), and insert tap water into the tap water hose insertion hole 14 of the lid 4. When the tip of a hose (not shown) is inserted and the tap is opened, the tap water passes through a heat exchanger and is received as hot water in a receiving container.

Note that the bag containing barley tea can also be directly put into the kettle body without attaching a tea strainer to the lid 4.

〔effect〕

This kettle has the following effects.

(1) When you boil barley tea with this kettle, the boiled barley tea is cooled by a heat exchanger that passes tap water, so the water cooling time can be shortened to about 10 minutes, 1/10 of the conventional time, and the use of cooling water is reduced. The quantity can also be significantly reduced.

(2) Since the water received from the heat exchanger into the receiving container is hot water, this hot water can be used for other purposes, making it economical.

Claims (1)

[Scope of utility model registration request] A heat exchanger made of vertical cylindrical spiral metal pipes is suspended from the lid attached to the kettle body, and both pipe ends penetrate the lid, and one end of the drain pipe is rotatable at one end of the kettle. A kettle characterized in that the water hose is connected to the pipe and a tap water hose connection part is formed at the other end of the pipe.
