Description

Food Waste Treatment Apparatus}

The present invention relates to a food waste reduction device, and more specifically, in the process of pulverizing food waste, by preventing solid residues from pulverized food waste, rather than water, from being discharged into the sink drain, sewage pollution can be reduced and pipe clogging phenomenon can be reduced. This relates to a food waste reduction device whose structure has been improved to prevent and improve the efficiency of food waste reduction and treatment.

The present invention arranges the driving part, such as a hand blender or a motor, to be located above the drain hole to facilitate maintenance of the parts. In addition, when the driving part rises, the strainer is raised to allow water to flow through the drain hole of the outer cylinder. This relates to a food waste reduction device whose structure has been improved so that water drainage can be performed smoothly by inducing water leakage.

In general, modern people's lives are in a much more prosperous environment compared to the past due to the advancement of science and technology. Although the problem of hunger still remains, in most developed countries, the amount of food waste due to the overflow of food is so great that much attention is paid to handling it. It occurs, and most food waste is processed through a food grinder in the sink.

In Korea, food waste is approximately 15,000 tons per day (as of 2008), and the amount of food waste generated per person amounts to 0.35 kg. Even taking into account restaurant establishments that generate large amounts of food waste, this is equivalent to 15,000 tons of food waste per day for a family of four. It can be predicted that close to 1kg of food waste is generated in each household.

Each local government provides food waste bins to store food separately so that food waste can be collected in bulk. However, there is a problem that it is prone to corruption, especially in the summer, and once it decomposes, a strong odor is generated.

In addition, if food waste is discharged as is through the sewer, it quickly settles inside the sewer pipe and is prone to rotting, and this rotted food waste causes water pollution.

Recently, due to the expansion of sewage treatment plants, there are many places where domestic sewage does not flow directly into rivers, so grinding devices that are mounted on sink sinks and can grind food into small pieces have gradually become popular. Methods for easily discharging finely ground food waste and decomposing quickly naturally so as not to have a significant impact on water pollution are gradually expanding.

However, the pulverization rate varies depending on the size and type of food waste, and the pulverized food is not discharged effectively. In particular, when processing high-fiber food waste such as kimchi, fine pulverization is not possible, so a large load is applied to the motor. In addition to shortening the lifespan, there was a problem in that water backflow occurred when water discharge became difficult.

In addition, the connection between the part mounted on the sink and the grinder including the motor was screwed together, making it difficult to disassemble it at home, and there was a risk of electric shock or short circuit in an environment where the switch to drive the motor was easily exposed to moisture. There were many problems, and in the case of the foot switch, which was pressed with the foot, even children could easily access it, so there was a safety problem.

Conventional prior art related to existing food waste disposal devices includes water and Food waste disposal consisting of a connecting tank coupled to the lower part of the connecting tank so that food waste can be discharged together, a grinding tank coupled to the lower part of the connecting tank, an outlet formed on one side, and a motor and a cutter for grinding food waste inside. It consists of a grinding device for, and the cutter consists of the first, second, and third cutters.

Other prior art related to the existing food waste disposal device is fixed to the sink drain, as disclosed in Korean Patent Publication No. 10-1215310 "Food waste treatment device for a sink" (registration date: December 21, 2012), and has a plurality of A grinding chamber in which two first through holes are formed; a first impeller installed in the grinding tank to grind food waste inputted therein, and to discharge the ground food waste to the outside of the first through hole; a stirred fermentation tank that accommodates the grinding tank and ferments the ground food waste into a microbial carrier; a second impeller installed in the stirred fermentation tank to agitate the ground food waste; and a motor that rotates the first impeller and the second impeller.

However, in the prior art related to the existing food waste disposal device, the motor is arranged in a fixed structure inside the sink drain during the grinding process of food waste, but it is placed in the area where water drains, so that the power transmission part such as the motor gets wet with water. As it gets older, maintenance becomes difficult due to rusting.

In addition, in the existing food waste disposal device, if solid residues made of pulverized food waste, rather than water, pass through the drain, not only there is a risk of drain pipe clogging, but it also causes sewage pollution.
