DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage crushing apparatus for crushing organic waste from homes and businesses.

[0002]

2. Description of the Related Art Conventionally, in a built-in type garbage crushing apparatus represented by a disposer, water required for processing garbage is usually supplied manually. For this reason, there are problems such as a decrease in grinding efficiency due to a shortage of water, a clogging of a pipe, and a waste of resources due to an excessive amount of water.

[0003] In order to solve the above-mentioned problems, a garbage crusher with an automatic water supply mechanism has been devised. According to this method, the required amount of water can be automatically supplied to the garbage crusher. This water is supplied to the garbage crushing device indirectly from a washing metal fitting or the like, or is supplied directly to the garbage crushing device via a hopper. At this time, water is supplied from a water supply port provided separately from the garbage input port.

[0004]

However, when the hopper system is adopted to prevent the cross connection,
In the water supply pipe secondary side vertical pipe and water supply pipe secondary side horizontal pipe after the hopper, if the drainage of the garbage crushing equipment deteriorates, or if a large amount of drainage flows, there is a problem that sewage flows backward. Had. This sewage contains solids such as crushed garbage and soluble organic matter. If the sewage remains in the water supply pipe, the microorganisms grow due to nutrients in the sewage. In addition, when the sewage is evaporated by air, foreign matters such as solids, soluble organic substances, and microorganisms are dried and adhere to the inner surface of the hose as slime. For this reason, there has been a problem that the pressure loss of the water supply pipe increases, and the wastewater flows backward from the hopper during long-term use of the disposer.

Further, from the viewpoint of preventing the backflow of sewage from the garbage crushing device to the water supply pipe, it is necessary to secure the air inlet and outlet of the crushing chamber, so that a closed structure cannot be obtained. There was also a problem that the crushing sound leaked and the usability was poor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a garbage crushing apparatus for preventing sewage from flowing back into a water supply pipe, maintaining sanitation of the water supply pipe, and quietly operating the garbage.

[0007]

The present invention has been made in view of the above-mentioned conventional problems. That is, the water supply port is provided independently of the garbage input port, and the garbage input port is sealed to prevent the crushing noise from leaking. This water supply port may be provided in the garbage crushing treatment device itself, or may be provided in the attachment of the garbage crushing treatment device.

[0008] The second point is that a backflow prevention mechanism is installed on the water supply side of the garbage crushing apparatus, so that sewage flows back through the water supply pipe regardless of pressure fluctuations in the garbage crushing chamber and deterioration of drainage performance. I did not do it.

A third gist is that a convex pipe is provided between the water supply pipe and the water supply port of the kitchen crusher as a means for preventing backflow, and after the garbage is pulverized, clean tap water is used to clean the secondary side of the water supply pipe. The tubes were submerged and sterilized with available chlorine in tap water. The water supply pipe and the pipe on the secondary side of the water supply can be made of a hard material such as metal or a soft material such as a hose.

A fourth gist of the present invention is to provide a water supply vertical pipe at the water supply port to have an effect of preventing backflow of water.

A fifth aspect of the present invention is to provide a connecting device having a trapping function between the vertical pipe on the secondary side of the water supply pipe and the horizontal pipe on the secondary side of the water supply so as to have a backflow preventing effect.

A sixth gist is to reduce the diameter of the secondary vertical pipe on the water supply pipe in order to prevent overflow from the hopper due to a decrease in the water supply capacity of the water supply pipe due to an increase in flow path resistance accompanying the installation of the convex pipe. The pipe diameter was made larger than the pipe diameter.

[0013] A seventh gist is to prevent the overflow from the hopper due to a decrease in the water supply capacity of the water supply pipe due to an increase in the flow path resistance due to the installation of the convex pipe, so that the height of the pipe below the upstream of the convex pipe ( Level), so that a siphon effect occurs during automatic water supply.

An eighth aspect is to provide a vacuum breaker to further enhance the backflow prevention effect. The position of the vacuum breaker may be immediately after the water supply valve or immediately before the disposer.

A ninth aspect is that a check valve is used as a backflow preventing means for the water supply pipe. The position of the check valve may be immediately after the water supply valve or immediately before the disposer.

Any of the backflow prevention mechanisms described above may be used alone or in combination.
One or a plurality of them may be used in combination.

A tenth aspect of the present invention is to provide a crusher and a water supply control mechanism for performing water supply in accordance with the operation of the crusher.

The eleventh gist of the present invention is that a crushing device for performing water supply and operation of the water check mechanism in accordance with the operation of the crushing device, and a control mechanism of the water supply and water check mechanism are provided. It is.

In a twelfth aspect, the control device controls the water supply pipe to be water-sealed after the operation of the pulverizing section is completed.

A thirteenth aspect is that the water supply section, the water supply port, or both of the water contact sections are subjected to antibacterial treatment. This makes it possible to prevent the generation of slime of microorganisms.

In the fourteenth aspect, a cleaning port is provided so that a water supply pipe can be cleaned. This cleaning port is
It is desirable to provide on the extension of each hose so that a brush etc. can be inserted.

A fifteenth aspect of the present invention is that a chemical tube can be installed so that a water supply pipe can be periodically cleaned. An oxidizing agent such as sodium hypochlorite is desirably used in the chemical solution. Further, the medicine cartridge was provided with a sustained release mechanism using a permeable membrane and a slit so that the medicine was periodically charged.

The sixteenth gist is that a convex pipe, a vertical water supply pipe,
The washing port is built in the crushing section or fixed to the crushing section. As a result, the apparatus can be downsized, and the workability can be improved.
