Description

[Detailed description of the invention] This invention relates to a hot water dispersion device such as a coffee boiler, and is designed to prevent dust from entering the pouring pipe and to evenly pour a constant amount of hot water over the coffee powder in the chamber. It is something.

An embodiment will be described below with reference to the drawings. 1 is a coffee boiler main body, a base 3 having a heating part 2,
A water tank 4 containing water, a chamber 5 containing coffee powder, a decanter 6 in which the chamber 5 is placed on its top opening, one end communicating with the water tank 4 and the other end communicating with the chamber 5. It is composed of a pouring pipe 7 which faces the upper opening of the molten metal and whose middle part is wrapped around the heating part 2. As shown in FIG. 4, a diffusion member 10 for diffusing hot water in all directions is detachably attached to the tip of the pouring pipe 7. This diffusion member 10 has a cylindrical overall shape, has an open top surface to form an insertion portion 10a, a through hole 10b in the center of the bottom surface, and elongated holes 10c radially around the through hole 10b. Multiple rows are drilled. As shown in the figure, the elongated hole 10c is drilled in the radial direction up to the periphery of the bottom surface with a small distance from the through hole 10b. An inclined surface 10e is formed at the outer end of the elongated hole 10c so as to be inclined inwardly and upwardly. 13 is a filter.

With this configuration, as shown in FIG. 2, the hot water from the hot water pouring pipe 7 is diffused in all directions through the through hole 10b and long hole 10c of the diffusion member 10, and evenly poured onto the coffee powder G. Moreover, since the distal end of the pouring pipe 7 is covered with the diffusion member 10, dust, small insects, etc. are prevented from entering the pouring pipe 7.

Furthermore, when this diffusion member 10 and a conventionally used ordinary diffusion plate 20 are used as shown in FIG. 5, the hot water is evenly distributed from the diffusion member 10 to the upper surface of the diffusion plate 20 as shown in FIG. , the coffee powder G can be evenly poured through the dispersion holes 20a of the diffusion plate 20 more reliably.

Since the present invention is constructed as described above,
Hot water can be sufficiently poured onto coffee powder even without the conventional diffusion plate, and moreover, using this conventional diffusion plate allows for more effective pouring. Since the outlet of the pouring pipe is closed off with the diffusion member, dust and small insects will not enter the pouring pipe.
