Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a coffee boiler in which a coffee basket is detachably attached to the main body, and a coffee receiver is installed below the coffee basket.

Conventional configuration and its problems Conventionally, in this type of coffee brewer, the coffee liquid dripping from the coffee basket has been received by a coffee container on which a coffee container lid is placed. There was a drawback that steam from the coffee liquid rose from the spout and the opening of the coffee container lid and condensed on the main body and the coffee basket.

Purpose of the invention The purpose of the invention is to reduce condensation of coffee liquid vapor on the main body and coffee basket.

Structure of the invention In particular, the present invention provides a coffee container lid with an annular rib along the inner wall of the coffee container and an opening tube that hangs downward in the center and has an opening located below the lower end of the annular rib. By doing so, the intended purpose is achieved.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a substantially inverted L-shaped container, which partially includes a water tank 2 and an eaves portion 3. Reference numeral 5 denotes a coffee basket, which is removably secured to the container visor 3 by a flange 6 provided on the outer periphery of the upper end. 7 is a drip hole provided on the bottom of the coffee basket 5. Reference numeral 8 denotes a lever rotatably fixed to the back of the coffee basket 5. One end is equipped with a valve 9 for opening and closing the drip hole 7, and the other end is equipped with a coil spring 10. It is biased in the closing direction. A lever protrusion 11 is provided on the opposite side of the lever 8 from the coil spring 10.

Reference numeral 12 denotes a base attached to the lower side of the container 1, and in the base 12, below the coffee basket 5, there is a heating element 15 that integrally holds a sheathed heater 13 and a heating pipe 14. One end of the heating pipe 14 is connected to the bottom of the water tank 2 via a check valve 16, and the other end opens to the top surface of the coffee basket 5 via a rising pipe 17 and a discharge port 18.
Reference numeral 19 denotes a coffee receiving container for receiving coffee liquid, which has a spout 20 formed by deforming a part of its upper end outward, and has a heat insulating plate 2 made of an aluminum plate or the like.
1 on the heating element 15. 22
is a coffee container lid placed on the coffee receiver 19.

The coffee container lid 22 is provided with an opening tube 23 through which coffee liquid dripping from the drip hole 7 of the coffee basket 5 passes. The upper part of the open tube 23 forms an inverted V-shaped slope 24, and the lower end of the open tube 23 forms an inverted V-shaped slope 24.
It has a lower end hole 25 having a diameter smaller than the inner diameter of No. 3. Further, the outer flat portion 26 of the slope 24 is connected to the lever protrusion 11.
A notch 27 is provided at a position corresponding to the spout 20 of the coffee receiving container 19 on the coffee container lid 22 that comes into contact with the coffee container, so that coffee liquid can be poured even with the lid closed. 28 is a coffee container 19
This is an annular rib that hangs down along the inner periphery of the opening.
Although it is not necessary to provide the annular rib 28 over the entire circumference, it is provided at least around the spout 20 of the coffee container 19 (around the notch 27 of the coffee container lid 22). In addition, the opening tube 23
The lower end hole 25 is located below the lower end of the annular rib 28.

Next, the operating method in the above configuration will be explained.

Coffee powder is put into a coffee basket 5 through a paper filter, and the basket is suspended from the container visor 3.
When the coffee container lid 22 is placed on the coffee receiving container 19 and set on the heat insulating plate 21, the outer flat part 26 of the coffee container lid 22 touches the lever protrusion 1.
1 is pushed up, the valve 9 is lowered, and the drip hole 7 of the coffee basket 5 is opened. When water is poured into the water tank 2 and the sheathed heater 13 is energized, the water in the heating pipe 14 is heated and boiled, and hot water is poured into the coffee grounds in the coffee basket 5 through the outlet 18. The coffee liquid produced by eluting the coffee components in the coffee basket 5 drops through the drip hole 7 and passes through the opening tube 23 of the coffee container lid 22.
It accumulates in the coffee container 19. When the water in the water tank 2 runs out and the heating element 15 enters the dry firing state, the temperature of the heating element 15 rises, the thermostat 29 attached to the heating element 15 senses this temperature change and starts operating, and the sheath heater 13 is turned on and off, the coffee liquid 30 in the coffee receiver 19 is
Keep it at a warm temperature.

The coffee liquid 30 is normally kept at a temperature of 80°C to 90°C. At this time, steam is generated from the coffee liquid 30 and rises inside the coffee container 19, but an opening tube 23 is hung in the center and steam is generated in the periphery. Since the annular rib 28 is suspended, most of the steam stays in the space 31 between the open cylinder 23 and the annular rib 28. Since the upper surface of the coffee container lid 22 faces the indoor air, the temperature is low, and the steam accumulated in the space 31 condenses relatively quickly and travels through the outer wall of the opening tube 23 and the annular rib 28, and becomes coffee. It falls to the liquid 30 and is reduced. Since the diameter of the hole in the open tube 23 is made smaller, the coffee liquid can easily drip down, and on the other hand, it is difficult for steam to escape.

According to the experimental results of the example, the specific dimensions of the coffee container 19 and the coffee container lid 22 are as follows:
Coffee container 1 with a diameter of approximately 100mm and a height of approximately 90mm
9, the annular rib 28 is approximately 10 mm from the back surface of the flat portion 26.
mm or more, the lower end of the open tube 23 is made slightly (approximately 4 mm) lower than the lower end of the annular rib 28, and the lower end hole 25 of the open tube 23 is approximately 8 mm or less, the amount of steam leaking from the spout 20 and the opening Since the water is dispersed almost equally from both the cylinders 23 in a well-balanced manner, it is not sufficient to generate water droplets, and the water is dispersed on the way, so that dew condensation does not form on the lower surface of the coffee basket 5 or the lower surface of the container visor 3.

As shown in FIG. 3, the steam that rises directly to the opening surface 32 (shaded area) of the spout 20 of the coffee container 19 and the opening surface of the bottom hole 25 directly flows out of the coffee container lid 22. The area of the opening surface 32 and the lower end hole 25 is the same as that of the opening tube 23.
This is because the condensation space 31 is very narrow compared to the dew condensation space 31 surrounded by the annular rib 28, and most of the steam is reduced to water droplets on the coffee container lid 22 in the dew condensation space 31. Further, when the lower end of the open tube 23 is made a little lower than the lower end of the annular rib 28, steam leaks almost evenly from both the open holes 32 and 25.

Effects of the Invention As is clear from the above explanation, according to the present invention, a condensation space is created by providing a coffee container lid with an annular rib and an opening tube with an opening positioned below the lower end of the annular rib. By simply installing it, you can almost eliminate the problem of dew condensation on various parts of the coffee boiler, and the conventional drawback that the water content decreases and the concentration of coffee becomes concentrated while keeping it warm is also eliminated because most of the steam condenses. Since it is reduced cleanly, there is also the advantage that the coffee concentration hardly changes.
