Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coffee extractor used to extract coffee, tea, etc.

[Conventional technology]

For example, as shown in FIG. 7, the coffee extractor has a heating plate 3 housed in a bottle mounting portion 2 provided in the extractor body 1. This heating plate 3 is provided with a water boiling pipe 4 and a heater 5 using a sheathed heater or the like. A water supply pipe 7 that communicates with a water storage tank 6 is connected to the water boiling pipe 4, and the water sent from the water storage tank 6 is boiled by the heat of the heater 5, and is sent from the hot water supply port 10 through the water supply pipe 9 to the filter cup 1.
It is designed to flow out to 1. Below the filter cup 11, a coffee bottle 12 is placed on a bottle placement section 2.

The bottle 12 is placed on a heat insulating plate 15, and the coffee liquid collected in the bottle 12 is kept warm. This heat insulating plate 15 is provided on top of the heating plate 3 so as to receive the heat from the heating plate 3.

The conventional mounting structure of the heating plate 3 and the heat insulation plate 15 is as follows.
As shown in FIG. 8, the heating plate 3 and the heat insulating plate 15 are fixed to the bottle mounting portion 2 using a mounting fitting 20, a threaded rod 21, a nut 22, and the like.

That is, the upper end of the threaded rod 21 is fixed to the heat insulating plate 15 by spot welding or the like, and the threaded rod 21 is inserted into the hole of the mounting fitting 20 and the nut 22 is tightened. In addition, the mounting fittings 20 are attached to boss portions 24 provided at multiple locations on the extractor main body 1.
Fixed. The heating plate 3 and the heat insulating plate 15 are previously connected to each other and integrated by a nut 26 screwed into the middle of a threaded rod 21. Further, a pipe 28 through which a threaded rod 21 is inserted is provided between the heating plate 3 and the mounting fitting 20. This pipe 28
is the mounting bracket 20 when the nut 22 is tightened.
It functions as a spacer to limit the deflection of the spacer.

According to the above configuration, the nut 22 is attached to the mounting bracket 2.
By tightening to 0, the heating plate 3 and the heat retaining plate 15 can be simultaneously fixed to the extractor main body 1 via the threaded rod 21 and the mounting fittings 20.

[Problem that the invention attempts to solve]

However, in the above structure, the heating plate 3 is attached to the mounting bracket 2.
Since the relative position of the heating plate 3 in the rotational direction around the threaded rod 21 is not determined with respect to the heating plate 3, it is difficult and time-consuming to correctly set the orientation, that is, the mounting position, of the heating plate 3 during assembly. Furthermore, a spacer pipe 28 is required between the heating plate 3 and the mounting fittings 20, which increases the number of parts.

[Means for solving problems]

The present invention is applied to a coffee brewer in which a heating plate equipped with a heater is housed in the bottle placement part of the extractor body, and a heat insulating plate is arranged on the upper surface of the heating plate. In the present invention, the heating plate is supported on the extractor main body by a mounting fitting fixed to the extractor main body, and the heating plate is attached to the heating plate by fitting into a part of the heating plate. It is characterized by integrally provided with a standing leg part that restricts the movement of the body.

[Effect]

In the coffee extractor with the above configuration, when the heating plate is assembled to the extractor body, the rising legs of the mounting bracket fit into a part of the heating plate, so that
The heating plate can be positioned with respect to the mounting fittings, and the mounting position of the heating plate with respect to the extractor body can be set accurately and easily.

〔Example〕

In one embodiment shown in FIGS. 1 to 3, the extractor body 1 is an integrally molded product made of synthetic resin, and a bottle mounting portion 2 extending horizontally is provided in a part of the extractor body 1.
is formed. A heat insulating plate 15 is fitted into the circular hole 2a formed in the bottle placement part 2, similar to the one in FIG. 7, and the bottle 12 is placed on the heat insulating plate 15. There is.

A heating plate 3 is housed inside the bottle placement part 2. The heater base 30 constituting the main body of the heating plate 3 is a cast product of, for example, aluminum alloy. However, it may also be a machined product.

The planar shape of the heater base 30 is generally circular, and a water boiling pipe 4 and a heater 5 using a sheathed heater or the like are embedded in the periphery thereof. Each end portion 4a, 5a of the water boiling pipe 4 and the heater 5 protrudes to the outside of the heater base 30. Also heater base 3
0 is provided with a hole 31 that penetrates in the vertical direction. A plurality of holes 32 are formed in the circumferential direction around this hole 31, and a grid-like fitting portion 33 is formed between each hole 32.

The heat retaining plate 15 is arranged on the upper surface side of the heating plate 3. The heat insulating plate 15 is press-molded from a metal plate such as aluminum or stainless steel, as in the conventional one, and has a substantially circular planar shape. A threaded rod 21 is fixed to the center of the lower surface of the heat insulating plate 15 by spot welding or the like. This threaded rod 2
1 has two nuts 22 and 26 screwed onto it. That is, the threaded rod 21 and nuts 22, 26 constitute a tightening member.

The heat insulating plate 15 and the heating plate 3 are integrated in advance by screwing a nut 26 into the intermediate portion of the threaded rod 21 and tightening them together. Further, a gasket 38 such as an O-ring is provided between the heat retaining plate 15 and the extractor main body 1.

The heating plate 3 and the heat retaining plate 15 are supported by the extractor main body 1 using mounting fittings 40. This mounting bracket 40 is made by bending a metal plate punched into a predetermined shape, and includes a body part 41 that extends in the horizontal direction, and a pair of vertically extending leg parts 43 that stand up on both left and right sides of this body part 41. It consists of. A locking portion 44 that fits into the fitting portion 33 is provided at the upper end of each rising leg portion 43 . Further, a hole 46 through which the threaded rod 21 is inserted is formed in the center of the body portion 41 . Holes 48 are provided at both ends of the body portion 41 to fit into the boss portions 24 provided in the extractor main body 1.
is formed.

To attach the heating plate 3 and heat insulating plate 15 to the extractor main body 1 using the above-mentioned mounting fittings 40, first stack the heating plate 3 on the heat insulating plate 15 and tighten the nuts 26. Let's integrate them. Next, by inserting the heating plate 3 into the hole 2a of the bottle placement part 2 and fitting the mounting bracket 40 into the boss part 24, the locking part 44 of the mounting bracket is connected to the fitting part 33 of the heater base. The end of the threaded rod 21 is made to protrude from the hole 46 while being fitted into the hole 46. In this state, the nut 22 is screwed onto the threaded rod 21, and the nut 22 is tightened until the locking part 44 abuts against the fitting part 33, as shown in FIG. By this tightening, the heating plate 3 and the heat insulating plate 15 are fixed to the extractor main body 1 via the threaded rod 21 and the mounting fittings 40.

According to the above configuration, the rising legs 43 provided on the mounting bracket 40 fit into the fitting portions 33 provided on the heating plate 3, thereby causing the mounting bracket 4
Since the relative position between 0 and the heating plate 3 is determined, the mounting position of the heating plate 3 with respect to the extractor main body 1 can be set accurately and easily. It is also possible to prevent the heating plate 3 from shaking in the rotational direction.

Moreover, in order to prevent the mounting bracket 40 from further bending due to the riser leg 43 hitting the heater base 30 when the nut 22 is screwed in by a predetermined amount, the length of the riser leg 43 is adjusted appropriately. By setting this, it is possible to limit the deflection of the mounting fitting 40, and also prevent the mounting fitting 40 from becoming sagging. Therefore, there is no need to separately provide a spacer member such as a pipe, which was required in the past. Further, in the above embodiment, the rising leg portion 4
Since the upper end of the nut 26 presses the heater base 30 against the heat insulating plate 15, the nut 26 can be omitted.

In addition, as shown in FIG.
The heating plate 3 can be prevented from rotating even if it is not pressed against the fitting part 33 but is slightly floating. However, in this case, it is necessary to connect the heating plate 3 and the heat insulating plate 15 using the nuts 26.

FIG. 5 shows another embodiment of the present invention, in which a fitting part 50 is provided on the outer periphery of the heater base 30,
The upper end of the rising leg portion 43 is fitted into this fitting portion 50. The fitting portion 50 is a recess, a hole, or the like.
