Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a coffee brewer, and particularly provides a coffee brewer suitable for obtaining low-temperature coffee liquid such as iced coffee.

In conventional coffee boilers of this type, the heating section has the functions of boiling water and keeping the extracted coffee liquid warm, but users do not necessarily want hot coffee liquid. However, when you want coffee liquid at a moderate temperature or when making iced coffee, there is no need for heat retention, and the above-mentioned coffee boiler with a heating part has the drawback of being difficult to use.

The present invention aims to improve upon these drawbacks, and provides a coffee boiler in which the warming operation can be arbitrarily selected through simple operations.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a coffee boiler main body, which includes a machine chamber 4 having a motor 3 on the upper surface of the base 2, and a mill container 6 having a cutter 5 provided at the upper part of the machine chamber 4 and driven in conjunction with the motor 3. , coffee receptor 7
A heating unit 8 is placed on the top surface thereof, and a water tank 9 is installed above the coffee receiver 7 and on the outer surface of the mill container 6.

The mill container 6 is removably housed in a recess 10 formed on the upper surface of the machine room 4, and the cutter 5 and filter 11 described above are placed inside the mill container 6.
and a diffusion plate 12. The heating section 8 has a heater (not shown) embedded therein, and is wrapped around a pipe 15 with one end facing the water tank 9 and the other end facing above the diffusion plate 12. Furthermore, an opening 16 is formed in the base 2 located on the upper surface of the heating section 8 . A plurality of recesses 20 are formed on the upper surface of the heating section 8 . 21 is a heat insulating plate having approximately the same shape as the heating section 8;
A convex portion 22 corresponding to the concave portion 20 is formed at a proper location, and a knob 23 is formed on one side.

And the action is that the water from water tank 9 is pipe 1
5 and heated in the heating section 8, the hot water is poured into the coffee powder ground by the cutter 5 through the diffusion plate 12, and the filtered coffee liquid is passed through the outlet 25 to the coffee receiver. The coffee liquid is stored in the cup 7 and kept warm by the heated heat insulating plate 21.

At this time, as shown in FIG. 3, the convex portion 22 of the heat insulating plate 21 and the concave portion 20 of the heating portion 8 are aligned, and the heat insulating plate 21 and the heating portion 8 are in close contact with each other. When it is not necessary to keep the coffee liquid warm, the heat insulating plate 21 is rotated using the knob 23 as shown in FIG. By almost eliminating the contact area with the coffee receiver 8, the heat conduction from the heating part 8 to the coffee receiver 7 is eliminated.

Since the present invention is constructed as described above,
By simply rotating the heat insulating plate at will, the user can select whether or not heat insulating is necessary, and can obtain low-temperature coffee liquid such as hot coffee or iced coffee.
