Food waste disposer installed to a sink}

The present invention relates to a food waste disposal apparatus, and more particularly, it is installed in a sink of a home kitchen, and the food waste can be automatically collected in a separate collection area by crushing and dehydrating food waste, minimizing volume and weight. It relates to a processing device.

As is well known, the intensive increase in the amount of food waste generated in the city due to the increase of urban population has caused various social, economic, and environmental problems, and the public with various technologies, institutions, and garbage problems to solve these problems. Efforts are being made to improve social awareness.

In general, there are methods for treating food waste, such as fermentation, incineration, recycling of feed and fertilizer (compost), and landfill in the ground, but as described above are large-scale facilities In addition to the need for a variety of side effects such as odor or discomfort associated with collection, transport or storage, it causes a social problem called NIMBY.

In such a situation, the above problems cannot be avoided unless ultimately the generation of food waste is completely suppressed. In general, food waste contains a lot of moisture, which is bulky and heavy, causing bad odors, and when incinerated, it causes a decrease in thermal efficiency and secondary environmental pollution, so it is best to minimize food waste. It's a solution.

In view of this, for example, Korean Utility Model Publication No. 99-7556, published on February 25, 1999, entitled “Sink substitute food waste disposal apparatus”, has been proposed. This design, as shown in Figure 1, the upper flange 111 of the main body 110 is coupled to the lower portion of the drain (S ₁ ) of the sink (S) is installed, the grinding chamber 112 of the main body 110 A grinding disc 113 having a grinding chamber 114 is provided in the center of the grinding disc 113, which is connected to the motor shaft 116 of the motor 115 located below.

One side of the grinding chamber 112 is provided with a drain pipe 118 connected to the drain hole 117, and an end 118 ′ of the drain pipe 118 is an upper center of the drying chamber 120 disposed below the motor 115. The dehydrator 121 provided in the drying chamber 120 is connected to the dehydrator 121 formed in the filter net 122 installed at the same time, and the dehydrator 121 provided in the drying chamber 120 is detachably connected to the motor shaft 126 of the motor 125 provided below. .

Is provided. This design is controlled by the controller 130 connected to the main body 110, the time, the heater and the indicator light.

However, the conventional food waste treatment apparatus as described above has a problem that requires a relatively large installation space because the grinding chamber for crushing the food waste and the dehydrated food waste are dehydrated and the drying chambers which are less than dry are arranged in series up and down. There is this.

In addition, a larger problem requires a motor for driving the grinding chamber and a motor for dewatering the crushed food waste in order to crush the food waste, so that the manufacturing cost is increased and the total weight is increased. There was a problem that the repair is not easy.

In addition, since the collected food waste is processed after the user opens and closes the door, there is a problem in that it is inconvenient to use.

Therefore, the object of the present invention can be made more compact, and by crushing food waste with one motor and dewatering the crushed food waste, the manufacturing cost can be low, and because it is relatively light, easy to install and repair It is to provide a food waste disposal apparatus.

Still another object of the present invention is to provide a food waste processing apparatus that can easily process the collected food waste by a user.
