However, it should be understood that the present invention is not limited to the disclosed embodiments, but may be implemented in various forms, and the present embodiments are not intended to be exhaustive or to limit the scope of the invention to those skilled in the art. It is provided to let you know completely. The shape and the like of the elements in the drawings may be exaggerated for clarity, and the same reference numerals denote the same elements in the drawings.

FIG. 1 is an exploded perspective view illustrating a food waste drying apparatus according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view illustrating a food waste drying apparatus according to an embodiment of the present invention.

As shown in FIGS. 1 and 2, a drainage net 10 is generally installed in a drainage hole 31 of a water supply line 30 disposed in a kitchen environment. Here, the food waste drying apparatus 100 according to the present embodiment is disposed in the water line 30 and rotates the drainage net 10 into which the food waste is introduced.

Thus, the drying apparatus 100 can dry the food waste put into the drainage net 10 without transferring the food waste. Therefore, the drying apparatus 100 can prevent contamination due to foreign matter that may be generated during transportation of the food waste, and has an advantage that it can be easily installed.

The drying apparatus 100 includes a supporting portion 110, a driving portion 130, a coupling portion 150, a driven shaft 170, and a cover 190.

First, the support portion 110 is disposed above the drainage net 10. Here, the supporting portion 110 supports the driving portion 130. For example, the support portion 110 is provided in the form of a plate and supported by the counterbore 30. Here, the support portion 110 may be constrained to the drain hole 31 into which the drainage net 10 is inserted, and the lower surface may have a stepped portion. Therefore, the driving unit 130 can be firmly and stably supported on the drainage net 10.

A plurality of first air inflow holes (111) are formed in the support part (110). The first air inflow hole 111 allows the upper space of the supporter 110 to communicate with the lower space of the supporter 110 where the drainage net 10 is disposed to allow air to flow smoothly.

Meanwhile, the driving unit 130 may include a rotation motor 131 and a driving shaft 133.

First, the rotary motor 131 is supported by the supporting portion 110. The driving shaft 133 is connected to the rotating shaft of the rotating motor 131. The driving shaft 133 may be disposed to penetrate the supporting portion 110. Here, a coupling portion 133a to be coupled to a coupling portion 150, which will be described later, is formed in the lower portion of the drive shaft 133. [ The coupling part 133a may protrude from the lower end of the driving shaft 133 and may be inserted into the coupling groove 151 formed in the coupling part 150. [

Meanwhile, the coupling portion 150 connects the driving shaft 133 and the driven shaft 170 with each other. First, the coupling part 150 may include a coupling groove 151 and a coupling groove 155 for coupling the driving shaft 133 and the coupling part 150 to each other.

3 is a perspective view showing a coupling between a drive shaft and a coupling part of the food waste drying apparatus according to the present embodiment.

3, the coupling groove 151 is recessed from the upper end of the coupling portion 150, and the coupling portion 133a is inserted inward. Here, the drive shaft 133 and the coupling portion 150 can be fastened by the fastening pin 155. At this time, the fastening pin 155 may penetrate the side wall of the coupling part 150 and be inserted into the rectangular positioning hole 133aa formed in the fastening part 133a.

Here, the position adjustment hole 133aa has a long axis in the longitudinal direction of the drive shaft 133. [ The position adjusting hole 133aa may be formed such that the position of the lower end of the coupling portion 150 with respect to the upper end of the driven shaft 170 is variable in connection of the coupling portion 150 and the driven shaft 170. [ For example, in the case of general drainage networks, the height of each drainage network may be different. In the case of a drainage network, it is common to produce it in a standardized manner, but the height of the drainage networks from the supporting surface may be slightly different. Thus, the position adjusting hole 133aa allows the separation distance between the driving shaft 133 and the coupling portion 150 to be adjusted so that the coupling portion 150 And the driven shaft 170 can be smoothly connected to each other.

Referring again to FIGS. 1 and 2, the detachable groove 153 is recessed from the lower end of the coupling portion 150. Here, the detachable portion 171 of the driven shaft 170 can be inserted and screwed into the detachable groove 153. At this time, the coupling portion 150 may be formed with a guide groove 157 for guiding the detachable portion 171 to the detachable groove 153. The guide groove 157 may be provided in a braille shape extending downward from the detachable groove 153 toward the lower side of the coupling portion 150.

On the other hand, a buffer member 159 may be disposed around the upper end of the coupling portion 150. The shock absorbing member 159 serves to buffer shocks generated between the drive shaft 133 and the coupling portion 150 that are expanded and contracted by the position adjusting hole 133aa. Here, a general O-ring may be used for the buffer member 159. [

On the other hand, the driven shaft 170 is detachably fastened to the bottom surface of the drainage net 10. Here, the driven shaft 170 may include a detachable portion 171 and a drainage coupling portion 173.

First, the detachable portion 171 is formed on the upper portion of the driven shaft 170. The detachable portion 171 can be inserted and screwed into the detachable groove 153. At this time, the detachable portion 171 can be easily guided to the inside of the detachable groove 153 along the guide groove 157.

The drain mesh fastening portion 173 fastens the drainage net 10 to the driven shaft 170. [ Accordingly, the drainage network connecting portion 173 can rotate the drainage network 10 as the slave shaft 170 is rotated. For example, the drain mesh fastening portion 173 may include a first support plate 173a, a second support plate 173b, and a support plate fastening member 173c.

First, the driven shaft 170 may be arranged to penetrate the bottom surface of the drainage net 10. [

At this time, the first support plate 173a may protrude from the subordinate shaft 170 at a lower side of the drainage net 10. Here, the first support plate 173a may protrude in parallel to one surface of the drainage net 10. The second support plate 173b may be fastened to the driven shaft 170 adjacent to the inner bottom surface of the drainage net 10. [ Here, the second support plate 173b may have the same shape as the first support plate 173a. In addition, the support plate fastening member 173c can rotate the drainage net 10 as the slave shaft 170 is rotated by fastening the first and second support plates 173b to each other.

The driven shaft 170 is provided integrally with the second support plate 173b disposed on the inner bottom surface of the drainage net 10 and the second support plate 173b and the first support plate 173a are integrally formed with the support plate fastening member 173c, respectively.

On the other hand, the lid 190 is seated and supported on the upper side of the drainage net 10. Here, the coupling portion 150 may be disposed so as to pass through the cover 190. And a lower support jaw 191 may be formed on the lower surface of the lid 190. The lower support jaw 191 extends downwardly from the lid 190 so that the central region of the lid 190 is supported on the lower jaw 150a protruding from the outer wall of the coupling portion 150. [

A plurality of second air inflow holes 193 are formed in the cover 190. The second air inflow hole 193 may allow air to flow into the drainage net 10 as the drainage net 10 is rotated. A plurality of intake vanes 195 may be disposed on the upper surface of the lid 190. Here, the plurality of intake vanes 195 may be disposed adjacent to each of the plurality of second air inlet holes 193. The intake vane 195 can concentrate the air into the second air inlet hole 193 as the drainage net 10 is rotated.

The lid 190 prevents the food waste introduced into the drainage net 10 from diffusing to the outside of the drainage net 10 when the drainage net 10 is rotated, So that the drying process of the food garbage can be facilitated.

The support 110 may be provided with a stopper 113.

4 is a perspective view showing a stopper of the food waste drying apparatus according to the present embodiment.

4, the stopper 113 of the food waste drying apparatus according to the present embodiment supports the coupling portion 150 when the coupling portion 150 is separated from the driven shaft 170, Can be prevented from being rotated by the drive shaft 131 connected to the rotation motor 133. [

For example, the stopper 113 may be provided as the first and second support frames 113a and 113c. Here, the first support frame 113a is disposed on the lower side of the support portion 110. [ At this time, one end of the first support frame 113a may extend to the upper side of the support portion 110 through the support portion 110. The second support frame 113b may be connected to one end of the first support frame 113a from above the support 110. [

At this time, an elastic body may be disposed at the connection portion between the first support frame 113a and the second support frame 113b. The first support frame 113a is spaced apart from the upper jaw 150b of the coupling 150 by the elastic force of the elastic body at the time of the normal operation. However, when the coupling portion 150 and the driven shaft 170 are separated from each other, The first support frame 113a is rotated toward the coupling part 150 by the compression rotation of the frame 113b to support the upper step 150b of the coupling part 150. [ Thus, the stopper can prevent the rotation of the coupling part 150, and the separation of the coupling part 150 and the driven shaft 170 can be facilitated.

5 to 8 are views showing the operation of the food waste drying apparatus according to the present embodiment.

5 to 8, the drainage net 10 may first be inserted into the drain hole 31 of the water line 30 disposed in the kitchen environment. At this time, food waste may be contained in the drainage net 10. Further, the drainage net 10 may be in a state where the follower shaft 170 is fastened (see FIG. 5).

Thereafter, when the drying apparatus 100 is disposed on the wash compartment 30, the detachable portion 171 is fastened to the detachable groove 153 and the lid 190 is lowered to be supported on the drainage net 10 and the coupling portion 150 do. That is, the edge region of the lid 190 is supported at the upper end of the drainage net 10. The supporting part 110 may be supported on the water line 30 on the upper side of the drainage net 10. Here, the support portion 110 is provided with a stepped portion of the lower surface forcibly inserted into the drain hole 31, so that the driving portion 130 is firmly and stably supported on the water line 30 (see FIG. 6).

Then, the drive shaft 133 connected to the rotation motor 131 is rotated by the electric power transmitted from the outside. At this time, the driven shaft 170 is lifted up from the inside of the attaching / detaching groove 153 by the rotation of the coupling part 150. Thus, the drainage net 10 is supported by the driven shaft 170 and spaced apart from the bottom surface thereof (see Fig. 7).

When the upper end of the detachable portion 171 contacts the upper side of the detachable groove 153, the upper support jaw 192 of the lid 190 is positioned on the lower side of the upper jaw 152b formed around the upper portion of the coupling portion 150 And comes into contact with the perfecting ring R to be disposed. The perfecting ring R can mitigate the impact generated between the upper support jaw 192 of the lid 190 and the upper jaw 152b of the coupling part 150 and make them close to each other. The friction between the coupling portion 150 and the driven shaft 170 and the friction between the coupling portion 150 and the driven shaft 170 due to the friction between the coupling portion 150 and the driven shaft 170 and the contact between the upper support rim 192 of the lid 190 and the perfecting ring R, The lid 190 rotates together. Thus, the drainage net 10 supported by the driven shaft 170 is rotated in accordance with the rotation of the driven shaft 170, so that the food waste contained in the inside can be dried (see FIG. 8).

The lid 190 prevents the food waste from being released to the outside of the drainage net 10 during the rotation of the drainage net 10 and flows into the drainage net 10 through the second air inflow hole 193. [ It is possible to perform a rapid drying treatment on the food waste based on the air to be treated.

Thus, the food waste drying apparatus has an advantage that it can reduce the power consumed in drying the food waste, thereby reducing the energy consumption required for drying the food waste.

In addition, the food waste drying apparatus can dry the food waste directly into the drainage network in the kitchen environment, thereby preventing contamination of the surrounding environment that may occur during the movement of the food waste, There is no need to provide a separate space.

An embodiment of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
