Description

{Coffee Machine Combined with Wireless Pot}

More particularly, the present invention relates to a coffee maker capable of supplying hot water preliminarily heated to a target temperature so as to supply hot water of an optimal temperature from the time of coffee extraction, The present invention relates to a wireless kettle coffee machine which can be used as a wireless kettle.

The conventional coffee maker extraction device has a water reservoir for storing cold water at the same height as the coffee filter and a check valve in the middle between the water container and the heater located at the bottom of the machine. It was composed of pipes to raise. The driving principle of such a conventional device is mainly a heater located at the lower part, when heat is applied to the water inside the pipe, and when the check valve installed on the heater side is closed by the pressure of water expansion when heated, the pressure acts on the open side, The coffee was prepared by pushing it up into an open pipe at the extraction side and dropping it on the ground coffee.

In the conventional extraction method, at the start of extraction, cold water is accumulated in a pipe which rises to the extraction portion at a height equal to the level of the water bottle. When heating is started in the heater, heat is generated only in the water inside the pipe in contact with the heater When pressure is generated, the cold water inside the pipe at the same level as the water level is not heated but transferred to the coffee so that cold water having a temperature much lower than the temperature suitable for extraction is moved.

Even when the heater is heated and full-scale extraction is carried out, the coffee is delivered to the coffee at a low temperature of 84 to 87 ° C before being 95 to 97 ° C, which is the optimum temperature for extracting coffee, so that the best coffee taste can not be realized.

Further, bubbles are generated when pressure is generated while hot water is supplied, hot water supply is stopped when cold water is supplied, and steam is generated when supercooling is delayed. This is why coffee that has been put into a coffee maker rather than hand drip coffee lacks flavor and aroma.

There is no cold water to be supplied to the heater after the water is completely lowered in the water tank. After the check valve, the water remaining in the pipe after the check valve is moved to the upper side of the coffee filter. The water vapor which is vaporized by the high temperature of the heater generates noise and is dewed in the inside of the body, and the machine is always wet with water after extraction or extraction, which is not good for hygiene.

Disclosure of the Invention The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to continuously supply hot water of the optimum temperature for extracting coffee from the beginning until the end of extraction, Another object of the present invention is to provide a coffee machine with a wireless kettle that can be used in combination with a wireless kettle at a normal time.

In order to achieve the above object, a coffee maker according to the present invention includes a main body 20 and a power socket 11 for power connection. The coffee maker includes a main body 20, A water tank (10) located at the lower end and having a handle on one side thereof; A check valve (12) for checking whether or not water leaks from the bottom of the water bottle; A temperature sensor (13) located at a lower central portion of the water bottle for sensing temperature; A heater 14 for raising the temperature at the lower end of the water bottle 10; A temperature controller 15 for controlling the temperature; A main body 20 having a power socket 11 'for power connection with the power socket 11 of the bucket; A solenoid valve (21) located at a central portion of the main body and regulating hot water discharge; A filter unit 30 located below the main body 20 for filtering coffee; A coffee port (40) for receiving the coffee filtered by the filter section; And a supporter (22) for connecting and supporting the main body, the filter unit, and the coffee port.

In addition, in the present invention, the water bottle 10 is made of stainless steel, and when the water bottle 10 is separated from the main body 20, the check valve 12 is automatically closed so that it can be used as a wireless kettle .

In addition, the present invention may further include a bimetal for blocking electricity when the temperature of the main body 20 is overheated.

According to a preferred embodiment of the present invention, the coffee maker further comprises a roaster (50) and a grinder (60) on the side of the coffee maker.

According to the present invention, hot water preheated to the target temperature is supplied to the cold water stored in the water tank, so that the hot water of the optimum temperature can be supplied from the time of extracting the coffee. In addition, the water remaining in the water tank or the water supply pipe is drained and the water remaining in the pipe is eliminated, thereby suppressing steam generation to the utmost.

Further, the temperature of the hot water, the supply of the hot water, the interruption of the hot water, and the hot water discharge amount can be adjusted by the electromagnetic valve 21 to arbitrarily adjust the extraction time, thereby extracting the best coffee suited to the taste.

In addition, since the main body and the water bottle can be separated from each other, the coffee can be used as a wireless kettle when not lowered, which is economical.

FIG. 2 is a diagram of a wireless kettle coffee machine including a roaster machine 50 and a grinder 60, according to a preferred embodiment of the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a coffee machine combined with a wireless kettle according to the present invention will be described with reference to the accompanying drawings.

The above-described embodiments are illustrative and those skilled in the art will be able to make various modifications and alterations to the disclosed embodiments without departing from the spirit of the present invention. The scope of the present invention is not limited by these variations and modifications.

1, a coffee machine according to the present invention is a conventional coffee machine, in which a water bottle 10 is located at the top of the coffee machine and includes a power socket 11 for power connection with the main body 20, Is located at the lower end thereof.

A check valve (12) for checking whether water is leaking is located in the lower part of the water bottle. A temperature sensor (13) for sensing the temperature is located at the lower central part of the water bottle. The heater 14 is located.

The main body 20 has a power socket 11 'connected to a power socket 11 of the water bottle and a solenoid valve 21 is disposed at the center of the main body. Temperature, hot water supply, and interruption and hot water discharge amount can be adjusted, so that the extraction time can be arbitrarily adjusted, so that it is possible to extract the best coffee according to taste. Here, the main body may further include a bimetal to cut off electricity when overheated.

A lower portion of the main body 20 is provided with a filter portion 30 for filtering coffee and a coffee port 40 for receiving coffee filtered by the filter portion.

When the coffee is extracted, the heater 14 is controlled by the temperature sensor 13 to operate the heater 14 at an optimum temperature for coffee extraction of 95 to 97 degrees.

When the temperature reaches the target temperature, the electromagnetic valve 21 controlled by the temperature sensor 13 is opened to supply hot water to the filter portion 30 of the coffee to be extracted.

In the present invention, a water container containing hot water and a coffee filtering device are arranged vertically, and unlike a conventional coffee machine, hot water is supplied without any device. When it is desired to obtain only hot water in addition to the coffee extract, the heater 14 is controlled by the temperature sensor 13 to operate the heater to a desired temperature to obtain hot water of various temperatures required by the user.

When separating the main body and the water bottle, the check valve installed on the bottom of the water bottle stainless steel is automatically closed and the water does not leak, so that the water bottle can be conveniently separated and used as a wireless kettle.

According to a preferred embodiment of the present invention, as shown in FIG. 2, the coffee maker further includes a roaster (50) and a grinder (60) on the side of the coffee maker.
