Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a drip type coffee maker.

BACKGROUND TECHNOLOGY A drip type coffee maker generally has a hot water inlet 1a at one end and a number of hot water outlets 1b in the center as shown in FIG. Guide peripheral wall 1c connecting
The shower 1 equipped with the above is attached to the upper part of the pot accommodating part 2a of the housing 2, the hot water inlet 1a is connected to the hot water supply pipe 3, and the hot water supplied to the shower 1 through the hot water supply pipe 3 is Hot water is spouted from the hot water outlet 1b toward the basket 4 set in the pot accommodating portion 2a. In the figure, 5 is a pot and 6 is a heater, and water in a water tank (not shown) is heated and boiled by the heater 6 while being sent to the shower 1 through the hot water supply pipe 3.

Problems that the invention aims to solve By the way, in the case of conventional coffee makers,
A joint 7 made of rubber or plastic pipe as shown in FIG. 4 is used to connect the hot water inlet 1a of the shower 1 and the hot water supply pipe 3, and the joint 7 is inserted into the hot water inlet 1a at one end of the joint 7. , the other end was inserted into the hot water supply pipe 3 to connect the hot water inlet 1a and the hot water supply pipe 3, which caused the following problems.

(1) Place the shower 1 into the pot accommodating part 2 of the housing 2.
When assembling the hot water inlet 1a onto the upper part of the hot water supply pipe 3, a so-called misalignment may occur between the hot water inlet 1a and the hot water supply pipe 3.In such a case, the conventional joint 7 made of rubber or plastic is There are cases where the hot water inlet 1a and the hot water supply pipe 3 cannot be connected due to poor performance.

(2) Generally, a seal ring 8 as shown in FIG. 3 is attached to the bottom surface of the shower 1, and when the pot 5 is inserted into the pot accommodating portion 2a of the housing 2, the pot cap attached to the pot 5 is sealed. Since the shower 1 is tightly fitted into the recess 9a of the pot 9 and has a structure that prevents steam from leaking to the outside, when the pot 5 is inserted, the shower 1 is
Since the joint 7, which is made of conventional rubber or plastic pipe, has poor elasticity, the joint 7 may come off or the pot 5 may not be inserted.

The present invention has been made for the purpose of solving the above-mentioned conventional problems.

Measures to solve the problem We connected the hot water inlet of the shower to the hot water supply pipe with a bellows-shaped joint.

Function The bellows-shaped joint is highly flexible and stretchable, so even if there is a misalignment between the hot water inlet of the shower and the hot water supply pipe, it is relatively easy to connect the two. Furthermore, even if the shower moves up or down when inserting the pot into the housing, it expands and contracts in accordance with this movement, thereby reliably maintaining the connection between the hot water inlet and the hot water supply pipe.

EXAMPLE Next, the present invention will be explained with reference to FIGS. 1 and 2.
Note that parts that are the same as those in the prior art are designated by the same reference numerals and redundant explanations will be omitted.

In the figure, 7 is a bellows-shaped joint. The joint 7 is made of plastic or rubber, and has a cylindrical hot water inlet connection part 7a at one end for tightly fitting into the hot water inlet 1a.
Further, a cylindrical pipe connecting portion 7b for closely fitting the hot water supply pipe 3 is integrally formed at the other end. Then, by fitting the hot water inlet connecting part 7a to the outer periphery of the hot water inlet 1a and fitting the pipe connecting part 7b to the hot water supply pipe 3, the bellows-shaped joint 7 connects the hot water inlet 1a to the hot water supply. It is designed to connect pipe 3.

Note that 10 connects the hot water inlet connection portion 7a to the hot water inlet 1a.
The clip 11 is fastened to the pipe connection part 7.
Clip 1 that fastens b to hot water supply pipe 3
Reference numeral 2 denotes a cover plate to be placed over the upper part of the guide circumferential wall 1c, and 13 indicates a bush 14 provided on one end side, which is attached to the notch 1c' of the guide circumferential wall 1c, and the other end side extends to a water tank (not shown). A steam drain pipe 15 guides the steam in the peripheral wall 1c to the water tank. A steam drain pipe 15 guides the steam in the basket 4 and pot 5 in the pot accommodating portion 2a to the water tank.

Effects of the Invention As explained above, the present invention provides a hot water inlet 1a at one end, a hot water outlet 1b in the center, and a guide peripheral wall 1c connecting the hot water inlet 1a and the hot water outlet 1b. The shower 1 is attached to the upper part of the pot accommodating part 2a of the housing 2, the hot water inlet 1a is connected to the hot water supply pipe 3, and the hot water supplied to the shower 1 through the hot water supply pipe 3 is transferred to the hot water. From the outlet 1b to the pot accommodating section 2
In this coffee maker, the hot water is spouted toward a basket 4 set in a shower cup 4, and the hot water inlet 1a of the shower 1 is connected to the hot water supply pipe 3 by a bellows-shaped joint 7. It has the effects described below.

(1) Place the shower 1 into the pot accommodating part 2 of the housing 2.
Even if there is a misalignment between the hot water inlet 1a and the hot water supply pipe 3 when assembling it to the upper part of the hot water supply pipe 3, the flexibility and elasticity of the bellows-shaped joint 7 makes it easy to remove the hot water. The inlet 1a and the hot water supply pipe 3 can be connected.

(2) Even if the shower 1 moves up or down when inserting the pot 5 into the pot accommodating part 2a, the bellows-shaped joint 7 expands and contracts to follow this movement and connects to the hot water inlet 1a. To reliably maintain the connection of a hot water supply pipe 3.
