Abstract

PURPOSE:To keep operation sound silent and to prevent clogging from being caused in the vicinity of an intake for garbage of a screw by equipping both the screw inserted into a carrier pipe and a driving means thereof and constituting a dehydration basket of a cylindrical body and forming the inner diameter of the upper end side thereof smaller than the lower end side. CONSTITUTION:Garbage discarded into a garbage receiving vessel 3 is introduced into a carrier pipe 5 from an intake 5a of garbage by rotation of a screw 6. This garbage is carried toward a discharge port 5b of garbage by the screw 6 and moisture contained in garbage is dehydrated in this carrier process. Thereafter garbage is discharged into a refuse bag 8 previously set to the discharge port 5b of garbage. The inner diameter of a dehydration basket 4 is made narrow in the upper part thereof and enlarged in the lower part as the height of this basket is made lower. Because of dependence on the screw 6 by this constitution, garbage is safely and automatically treated while keeping operation noise silent without manual aid. Further for example, even when a large amounts of garbage are discarded at a time, clogging is not almost caused in the vicinity of the intake 5a for garbage of the screw 6.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a kitchen waste processing device, and more specifically,
This invention relates to a kitchen waste disposal device that can directly dump kitchen waste (raw garbage) from a kitchen into a garbage bag or the like while draining it.

[Conventional technology]

Many kitchen waste processing apparatuses for crushing and dewatering kitchen waste have already been proposed, such as Japanese Patent Publication No. 59-26345 and Japanese Patent Application Laid-Open No. 62-234555.

That is, in these conventional examples, a crushing blade and a dewatering basket are coaxially provided in a casing connected to the lower part of the kitchen waste inlet of the sink, and the kitchen waste to be thrown away is crushed by the crushing blade, and also After the contained water is dehydrated in a high-speed rotating dehydrator, it is collected in the dust box.

[Problem to be solved by the invention]

However, the above conventional example has a problem first of all in terms of safety. In other words, since the principle is the same as that of a mixer, there is a risk of serious injury if you insert your hand into it. To prevent such accidents, double or triple safety measures are required, and an increase in costs is inevitable. Additionally, if metal items such as spoons and knives are accidentally thrown away, the crushing blades may chip and the utensils may also be damaged. Furthermore, since the crushing blade and dehydrator rotate together at high speed, a large amount of noise is generated.

[Means to solve the problem]

In order to solve the above problems, in the present invention, a cylindrical kitchen waste receptacle having a kitchen waste inlet provided at the bottom of the sink is a container, the kitchen waste receptacle is a draining basket removably disposed inside the container, and the kitchen waste The receiver rises upward from the bottom of the container at a predetermined angle, and has a food waste intake port at its lower end and a food waste discharge port at its upper end, a transport pipe, a screw inserted into the transport pipe, and the same screw. and a drain pipe that communicates with the bottom of the container and discharges the waste water in the container, and in this case, the draining basket has a - mark on the upper end of the draining basket. It consists of a cylindrical body that has a matching opening and whose lower end is formed to fit into the kitchen waste intake port, and the inner diameter of the upper end of the cylindrical body is smaller than the inner diameter of the lower end of the cylindrical body. The structure is as follows.

[For production]

In the kitchen waste receptacle, the kitchen waste dumped into the container is taken into the conveying pipe through the kitchen waste intake port by the rotation of the screw.
The same screw transports the waste toward the kitchen waste outlet.

During this transportation process, water contained in the kitchen waste is drained. Thereafter, the kitchen waste is discharged from the kitchen waste discharge port into a garbage bag that has been set in advance at the kitchen waste discharge port.

In addition, the inner diameter of the drainer basket is narrow at the bottom and widens toward the bottom, so even if a large amount of garbage is pushed in at once, clogging will hardly occur near the kitchen waste intake 1. .

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

3- As shown in FIG. 1, this kitchen waste processing apparatus includes a cylindrical kitchen waste receptacle 3 having a kitchen waste inlet 2 provided at the bottom of a sink 1. In this kitchen waste receptacle, a drainer 4 made of metal or synthetic resin is removably housed in a container 3.

The kitchen waste receptacle is provided with a conveying pipe 5 at the bottom of the container 3 that rises diagonally upward from the bottom at a predetermined angle. A kitchen waste intake port 5a that opens at the bottom of the container 3 is formed at the lower end of the transfer pipe 5, and a kitchen waste outlet 5b is provided at the upper end of the transfer pipe 5.

The drainer 4 is a cylindrical body whose upper end opening 4a fits into the kitchen waste inlet 2 and whose lower end bottom 4b fits around the kitchen waste inlet 5a.According to the present invention, the upper end A neck portion 4C having an inner diameter narrower than other portions is formed near the opening 4a. That is, the inner diameter of the neck portion 4C is narrowed to be smaller than the inner diameter of the bottom portion 4b. According to this, for example, even if a large amount of food waste is dumped into the kitchen waste inlet 2, as long as it passes through the neck 4c of the drainer 4, clogging will not occur near the kitchen waste inlet 5a. There are almost no

A screw 6 is rotatably inserted into the conveying pipe 5. Further, a motor 7 for rotationally driving the screw 6 is attached to the lower end side of the conveying pipe 5. However, the motor 7 may be provided on the "-" end side of the conveying pipe 5.

Although not shown in detail, in order to efficiently drain water from the kitchen waste, the volume inside the conveying pipe 5 gradually decreases toward the end. As a method for this, the diameters of the conveying pipe 5 and the screw 6 are gradually made smaller as they go upward, or the diameter of the shaft of the screw 6 is made thicker. Furthermore, there is a method of increasing the helical pitch of the screw 6. In this example, an appropriate number of slit grooves extending along the axial direction of the conveying pipe 5 are formed in the conveying pipe 5 in order to efficiently return drained water to the container 3.

A garbage bag 8 made of a resin film is attached to the garbage discharge port 5b of the conveying pipe 5 with a suitable fastener 9 such as a band. Moreover, a sealing means 10 for heat-sealing the opening side of the garbage bag 8 is provided on the side of the garbage discharge port 5b. In this embodiment, a pair of heater plates 1 are opened and closed by operating a lever 11.
It consists of 0a and 10b.

In this device, the garbage bag 8 is placed, for example, in a case 13 provided on the front side of the sink 1, but in this case, the case 13 can be swung by a hinge 14 provided at the lower part of the back side. is supported by In addition, a magnetic plate 15 is provided on a part of the back side of the case 13, and a magnet 16 with the plate 15 as a counterpart is provided on the housing side of the device, as well as a microswitch that is turned on and off depending on the inclination angle of the case 13. 17 are arranged.

Referring to FIG. 2, a drain pipe 12 is connected to the bottom of the container 3 for draining waste water from the container. In this case, the drain pipe 12 is provided with a trap 12a for keeping the liquid level of the waste water stored in the container 3 at a level lower than that at the kitchen waste intake port 5a.

Here, the operation of this device will be explained. First, open the lid 13a of the case 13, and attach the garbage bag 8 to the garbage outlet 5b of the conveying pipe 5 using a suitable band, for example, on the lid 1.
3 Close a. At this time, since almost no weight is applied to the case 13, the case 13 is held in its normal position by the magnet 16, and the microswitch 17
is on. This state is maintained until a predetermined weight of garbage is accumulated in the garbage bag 8.

Next, kitchen waste is thrown in from the kitchen waste input port 2, but in that case, even if a large amount of food waste is thrown in at the same time, the draining basket 4 is provided with a neck 4C at the top, and the waste goes to the bottom. Since its inner diameter is widened accordingly, clogging phenomenon hardly occurs in the vicinity of the kitchen waste intake port 5a as long as it passes through the neck portion 4c.

When the screw 6 is rotated by the motor 7, the kitchen waste is conveyed through the conveying pipe 5 by the screw 6, and after being drained along the way, it is delivered to the garbage bag 8 from the kitchen waste discharge port 5b.
discharged inside. Large kitchen waste 8 - The waste is finely cut by the edge of the kitchen waste intake I-15a and the blade of the screw 6, and then taken into the conveying pipe 5.

In this way, the kitchen waste is discharged from the kitchen waste outlet 5b into the garbage bag 8, but when it becomes heavy,
The case 8 tilts toward the front of the device against the attraction force of the magnet 16. As a result, the microswitch 17 is turned off, the motor 7 is stopped, and a notification means such as a buzzer (not shown) is used to notify that the garbage bag 8 is full.

When the lever 11 is pushed down by the user, the pair of heater plates 10a and 10b sandwich the opening of the garbage bag 8, thereby heat-sealing the opening. Then, the garbage bag 8 is taken out and a new garbage bag is attached to the kitchen waste outlet 5b.

In addition, since the kitchen waste intake port 5a is submerged in the waste water stored in the container 3, the bad odor and foreign odor generated in the garbage bag 8 will not flow back to the sink 1 side.

〔Effect of the invention〕

As described above, according to the present invention, since it uses a screw, it is safer than conventional crushing blades and is quieter in operation.

In addition, kitchen waste can be automatically processed without any manual effort. In addition, by forming a neck in the upper part of the drainer basket with an inner diameter narrower than that in the lower part, clogging will hardly occur near the kitchen waste intake port 5a of the screw, even if a large amount of kitchen waste is dumped, for example. The effect is remarkable.
