[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mounting device for a heating element of a drip-type electric coffee boiler for general household use.

BACKGROUND TECHNOLOGY Conventionally, a drip-type coffee brewer has a structure in which a glass container for storing extracted coffee liquid is placed on a heating element attached to the bottom of the container to keep it warm. As shown in FIG. 4, the installation configuration of the heating element is as shown in FIG.
A heating element 4, which is integrally formed with a heating pipe 3 which introduces and heats water supplied by receiving heat from the container body 1, is attached to the vessel body 1 by a presser metal fitting 5. In order to mount the heating element 4 in a well-balanced manner, a protrusion 6 is provided approximately at the center of the heating element 4, a spring 7 is interposed in the protrusion 6, and the device is mounted with the spring 7 pressed by the presser metal fitting 5. It is attached to body 1. To attach the mounting bracket 5 to the body 1, hook the notch 8 provided on one side of the mounting bracket 5 onto the screw 9 tightened to the body 1, and fix the other end with the screw. The holding part of the spring 7 and the tightening part of each screw were arranged to be on the same line.

Problems to be solved by the invention However, in this configuration, the heating element 4
When it was attached to the vessel body 1, one side of the presser metal fitting 5 was raised due to the pressing force of the spring 7, making it extremely difficult to tighten the screws and making assembly difficult. Furthermore, the pressing part of the spring 7 and the tightening part of the screw are on the same line, and the mounting part of the spring 7 of the heating element 4 is located approximately in the center, and as a result, it is installed at the maximum diameter part of the heating element 4. To,
The size of the container was large, which caused problems such as taking up storage space.

The object of the present invention is to provide a heating element mounting device for an electric coffee boiler that solves the above-mentioned problems.

Means for Solving the Problems In order to solve the above problems, the present invention includes a heating pipe that introduces water from the back side to the bottom of the vessel body,
A heating element formed integrally with a sheathed heater that heats the water is positioned, a spring is interposed in the protrusion provided approximately at the center of the maximum diameter of the heating element, and the spring is pressed and both ends are A holding metal fitting to be fixed to the body is provided, and the mounting position of this holding metal fitting to the body is not on the same line as the pressing part of the spring but is shifted from the large diameter part of the heating element, and a cut is made on one side of this front holding metal fitting. A notch is provided, this notch is hooked onto a screw attached to the vessel body, the other end is tightened and fixed with the screw, and both end surfaces of the clamping side of this holding bracket are attached to guides provided on the vessel body. positioned,
In addition, a bent piece is provided on at least one side of both sides of the presser fitting in this portion.

Effect According to the above configuration, a heating element is set in the vessel,
When positioning the spring on the protrusion provided on the heating element and attaching it to the device using a presser, hook one end of the presser onto the screw tightened to the device, and attach the other end to the guide provided on the device. When positioned and set, since the mounting position and the spring mounting part are not on the same straight line, the presser metal fitting is pushed upward and a rotational force is applied at the same time, causing it to be twisted. However, both sides of the screw-fixed side of the presser metal are held by guides provided on the instrument body, and when the presser metal fitting is twisted, the bent portion hits the guide, and therefore the presser metal fitting is removed from the guide of the instrument body. It will not come off, and the screws can be tightened very easily, improving ease of assembly. Furthermore, since the holding metal fittings are fixed to the container body at a small diameter part, shifted from the largest diameter part of the heating element, the fixing pitch can be made smaller, and as a result, the container itself can be made smaller. This allows the vessel itself to be compact.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 to 3, reference numeral 11 denotes a container body of an electric coffee boiler, which has a built-in tank for storing water, and above is a filter container 12 for extracting coffee, and this filter container 12 and the container. body 11
The lid 13 that covers the tank lid 14, and the container body 11
It has a handle 15 for carrying. A glass container 16 for storing extracted coffee liquid is located below the filter container 12, and this glass container 16 is connected to a heating element 1 attached to the lower part of the container 11 via a gasket 17 and a heat insulating plate 18.
It is placed on 9.

The heating element 19 is integrally formed with a heating pipe 20 that introduces water from a tank and a sheathed heater 21 that heats the water in this heating pipe 20, and has a maximum diameter approximately at the center and a narrow width at the base. It is bent into a roughly U-shape. Furthermore, a convex portion 22 is provided approximately in the center of this heating element 19, and a spring 23 is positioned on this convex portion 22.
3 is pressed, a presser metal fitting 24 is provided, and both ends of this metal fitting 24 are fixed to the container body 11. Note that a notch 25 is provided at one end of this presser metal fitting 24, and the notch 25 is hooked onto the screw 26 tightened to the container body 11, and the other end is brought into contact with the container body 11, and the screw 27 is tightened.
Fix it by. The tightening positions of both ends of this presser metal fitting 24 are not on the same line as the spring 23, but are shifted in one direction.

Further, both sides of the presser metal fitting 24 on the side fixed by the screws are positioned and held by guides 28 provided on the device body 11, and this portion of the presser metal fitting 24 has a bent portion 2 on at least one side.
There are 9.

In the above structure, the assembly method and effects thereof will be explained. First, place the heating element 19 on the container 11 from the back side, insert the spring 23 into the convex part 22 at the center of the heating element 19, and then insert the notch 25 at one end of the presser metal fitting 24 into the container 11. It is hooked onto a pre-tightened screw 26, and while the spring 22 is pressed by a presser metal fitting 24, it is tightened and fixed to the container body 11 with a screw 27. In such an installation, since the tightening positions at both ends of the presser metal fitting 24 and the position of the spring 23 are not on the same line, the force of the spring 23 applied to the presser metal fitting 24 is applied not only upward but also in the rotational direction, causing the metal fitting 24 to be twisted. . At this time, hold down metal fitting 2
The side fixed by the screw 27 of No. 4 is held by a guide 28 provided on the container body 11, and since a bent portion 29 is provided on one side of the presser metal fitting 24, this bent portion 29 hits the guide 28 of the container body 11, and the guide Since the presser metal fitting 24 is stopped in an inclined state within 28, it will not come off. This makes it very easy to fix with the next screw 26, improving the ease of assembly. Furthermore, since the presser fitting 24 is not attached to the large diameter part of the heating element 19 but is fixed at a shifted position, the mounting pitch becomes smaller, and as a result, the size of the body 11 itself can be reduced, making it compact. This allows the installation of a heating element that does not take up much space.

Effects of the Invention As is clear from the description of the embodiments above, the present invention involves interposing a spring in the convex portion provided approximately at the center of the heating element, and pressing the spring and holding both ends of the heating element against the body using a presser metal fitting. The fixing position of both ends of this holding metal fitting is not on the same line as the pressing position of the spring, but is offset from the large diameter part of the heating element, and one end of the holding metal fitting is clamped by a guide provided on the body, and this clamping Since there is a bent part on at least one side of the presser fitting in the part where the heat generating element is attached and the presser fitting is set, the presser fitting will not come off and can be easily screwed.
The ease of assembly is very good. Furthermore, since the heating element is not fixed at the large diameter part, the installation dimensions are small, and as a result, the body itself is compact, so it does not require much space when stored. The practical effects are great.
