This application claims the benefit of Korea Patent Application No. 2003-82383 filed on Nov. 19, 2003, the disclosure of which is hereby incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an apparatus for producing confectionery.

2. Description of the Related Art

Confectionery is not limited to a hard preparation, but includes a soft preparation such as bread, a rice cake or the like. Such confectionery tastes delicious shortly after being baked.

Generally, the confectionery in circulation is massively produced by a confectionary factory that does hardly provide access to consumers. The produced confectionary is packaged and then transported over relatively long distance from the confectionary factory to the consumer, so that it takes relatively too much time to supply the consumer with the confectionery, thereby deteriorating the taste of the confectionery.

One example of an apparatus for producing the confectionery has been disclosed in U.S. Pat. No. 6,116,152, titled “apparatus for producing confectioneries,” in which the apparatus has a small size and can be installed in an incommodious space.

In the case of the apparatus disclosed in U.S. Pat. No. 6,116,152, a distribution channel can be shortened, so that it is possible to supply fresh confectionery to the consumer. As a result, the apparatus can not only satisfy the consumer's taste, but also enhance reliability of the confectionery. In addition, the apparatus can stimulate consumer's interest.

However, the conventional apparatus disclosed in U.S. Pat. No. 6,116,152 has the following problems:

First, a hopper for storing materials is partitioned into two portions, and dough and cream are stored therein respectively, so that it is difficult to clean the inside of the hopper. Further, the hopper is coupled to an upper surface of an injector by a bolt, so that there is additionally needed a tool for releasing the bolt in order to separate the hopper from the injector.

Second, a hose, which is connected with the injector and used to fill a confectionary mold with the materials, is connected to an intermediate shaft together with a rolling wheel. Here, the hose is made of a metal body which is integrated with the intermediate shaft, so that it is difficult to clean the hose. Further, to clean the hose, the hose should be separated from a main frame. To separate the hose from the main frame, the intermediate shaft should be also separated from the main frame. At this time, because the hose, the intermediate shaft and the rolling wheel are formed as a single body, it is difficult to handle them.

As described above, in the conventional apparatus disclosed in U.S. Pat. No. 6,116,152, it is inconvenient to clean the hopper and the hose used as a material injection unit.

SUMMARY OF THE INVENTION

FIG. 4 is a perspective view for illustrating an outlet of the hose attached in an intermediate shaft of the elevation unit in the apparatus according to an embodiment of the present invention.

Referring to FIG. 4, an outlet 432 of each of the hoses 43 and 43′ is fitted to each of nozzles 435 and 435′. In a connection portion between the outlet 432 and the nozzle 435, 435′, there is separately provided a clamp (not shown) to enhance clamping force. Further, the nozzles 435 and 435′ are provided on a holding plate 54 coupled to the intermediate shaft 53 of an elevation unit, wherein the holding plate 54 is formed with a nozzle holding hole 541. Among the nozzles 435 and 435′, the nozzle 435 is for injecting the inner or stuffing material, while the nozzle 435′ is for injecting the outer material. Thus, the nozzles 435 and 435′ fitted to the outlets 432 of the hoses 43 and 43′ are detachably provided on the holding plate 54.

Referring to FIG. 1, as a slider 51 of the elevation unit 5 moves in left and right directions, the rolling wheel 52 connected to the intermediate shaft 53 moves up and down along an inclined surface 511 of the slider 51, so that the holding plate 54 to which the outlets 432 of the hoses 43 and 43′ are fixed correspondingly moves up and down, thereby supplying two kinds of materials through the nozzles 435 and 435′ moved down adjacent to the confectionary mold.

FIGS. 5 a and 5b are views for illustrating operations of the material injection unit in the apparatus according to an embodiment of the present invention.

Referring to FIGS. 5a and 5b, inside the first and second injectors 42 and 42′, i.e., between the hopper coupling hole 421 and the hose assembly connecting hole 422, there are provided first and second switches 44 and 44′.

Thus, when the end block 3 travels left and right, the piston actuator 6 correspondingly allows the injectors 42 and 42′ to receive the materials from the hopper and to supply the received materials to the hose, thereby injecting the materials to the confectionary mold. Here, the piston actuator 6 is coupled to the end block 3 by a nut N, so that the piston actuator 6 can be easily detached from the end block 3 by releasing the nut N.

FIG. 7 is a view for illustrating a detached state of the material injection unit from the apparatus according to an embodiment of the present invention.

The hoppers 41 and 41′ are inserted in the hopper coupling holes 421 of the first and second injectors 42 and 42′ respectively, so that the hoppers 41 are 41′ are easily detached from the hopper coupling holes 421 by a predetermined force without a separate tool. Further, the injectors 42 and 42′ can be easily detached from the installation plates 21 and 21′ by releasing the installation handles 211. Also, each of the hoses 43 and 43′ has the inlet 431 and the outlet 432 fitted to the hose assembly connecting hole and the holding plate 54, so that the hoses 43 and 43′ can be easily detached therefrom without a separate tool. Additionally, the piston actuator 6 provided in each of the injectors 42 and 42′ can be easily detached from the end block 3 by releasing the nut N.

Thus, in the present apparatus 1 for producing the confectionery, the elements forming the material injection unit 4 are easily detached from the main frame 2 without a separate tool, so that it is convenient to clean the hoppers 41 and 41′, the injectors 42 and 42′ and the hoses 43 and 43′ and to then couple them to the main frame 2 without a separate tool.

As described above, the present invention provides an apparatus for producing confectionery, in which components of a material injection unit, such as a hopper, an injector and a hose, are detachably formed, so that the hopper, the injector and the hose can be easily cleaned and be kept sanitary.
