Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a kitchen waste disposal device that can directly dump kitchen waste from a kitchen etc. into a garbage collection bag while draining it. This invention relates to a bag volume detection means.

[Conventional technology]

Many kitchen waste processing apparatuses for crushing and dewatering kitchen waste have already been proposed, such as those disclosed in Machiai WR59-26345 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 The contained water is dehydrated in a high-speed rotating dehydration basket and then collected in the dust box.

[Problem to be solved by the invention]

As mentioned above, kitchen waste is dehydrated, pulverized and collected in a dust box, but in conventional equipment,
No particular measures have been taken to detect the amount collected in the dust box, and therefore the user must frequently inspect the dust box, which is troublesome. Furthermore, if you ignore this and use the device with the dust box full, not only will the performance of the device be affected, but there is also a risk that the residue will overflow and pollute the surrounding area.

[Means to solve the problem]

In order to solve the above problems, in the present invention, a kitchen waste receptacle having a kitchen waste inlet provided at the bottom of the sink is provided with a container, and the kitchen waste receptacle separates the kitchen waste dumped into the container from water and removes the kitchen waste. A kitchen waste processing section that processes kitchen waste to make it suitable for bagging, a kitchen waste discharge section that discharges the kitchen waste processed in this kitchen waste processing section into a garbage collection bag, and a garbage collection bag storage located on the opposite side of this kitchen waste discharge section. In the kitchen waste disposal device, the garbage collection bag storage section includes a case body consisting of a box with a predetermined volume for storing the garbage collection bag, and a lid pivotally connected to the case body so as to be openable and closable. , a structure comprising a lid holding means that holds the lid closed to a predetermined value against the pressing force due to the swelling of the garbage collection bag, and a lid opening/closing detection means that detects the opening of the lid and controls the kitchen waste processing section. It is said that

In this case, the lid holding means preferably consists of a combination of a magnet and a magnetic material that is magnetically attracted to the magnet. Further, as the lid opening/closing detection means, a micro switch or a magnetic proximity switch is used.

[For production]

According to the above configuration, the garbage collection bag is swollen by the amount of kitchen waste discharged from the garbage discharge section, and the lid is pressed in the direction of opening by the bulge. When the pressing force exceeds the holding force of the lid holding means, the lid is opened, and this is detected by, for example, a microswitch, and the food waste processing section is stopped by the detection signal.

〔Example〕

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

FIG. 1 shows an embodiment of a screw type kitchen waste processing apparatus, and first, its overall configuration will be explained.

That is, this kitchen waste processing apparatus includes a cylindrical kitchen waste container 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.

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 upper end side of the conveying pipe 5.

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 wastewater stored in the kitchen waste container 3 above the kitchen waste intake port 5a.

Although not shown in detail, in order to efficiently drain water from kitchen waste, the volume of the inside of the conveying pipe 5 is increased.

It gradually becomes smaller towards the top. 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. Although not shown in the figure, in this example, a container 3 is provided in the conveying pipe 5 to efficiently receive the drained water.
A suitable number of slit grooves are formed extending along the axial direction of the screw in order to provide resistance to the kitchen waste being returned to the inside of the screw and rotating integrally with the screw.

A case body 13 constituting a storage section for the garbage collection bag 8 is arranged below the garbage discharge port 5b of the conveyance pipe 5. This case body 13 is provided with a lid 13a that can be opened and closed. According to this embodiment, the case body 13 is swingably supported on the housing side of the device by a hinge 14 provided at the lower part of the back side of the case body 13. Also, the back side of the case body 13.

A magnetic plate 15 is provided on the upper part, and a magnet 16 with the plate 15 as a counterpart is provided on the housing side of the device.
A microswitch 17 that is turned on and off depending on the inclination angle of the case body 13 is arranged. The case body 13 is normally set at the set position (non-rotating position) by the magnet 16.
When the weight of garbage inside the garbage collection bag 8 exceeds the holding force, the case body 13 rotates, that is, tilts counterclockwise as shown in the figure.
is rotatably supported, but the key is to provide a fulcrum at a position offset from the center of gravity so that the fulcrum can be rotated around the fulcrum. For this purpose, a hinge is not necessarily necessary; for example, a protrusion is provided on the casing side to abut a part of the bottom of the case body 13 and support the case body 13 at a position away from its center of gravity, and the case body 13 is placed on the protrusion. It may be arranged so that it can be attached and detached.

As shown in FIG. 3, a magnetic plate 20 is provided on the top of the % 13a, a magnet 21 with the plate 20 as its counterpart is provided on the device housing side, and the lid 13a is normally closed. It is held closed by this magnetic adsorption means. Further, an engagement piece 22 is provided upright on the upper side of the lid 13a, and the engagement piece 22 is provided on the housing side.
A microswitch 23 having a counterpart 2 is provided. Note that, unlike this example, the magnet 21 is attached to the lid 13.
placed on the a side.

When the magnetic plate 20 is provided on the housing side, a magnetic proximity switch using the magnet 21 as the object to be tested can be used in place of the microswitch 23.

A kitchen waste discharge pipe 9 extending into the case body 13 is connected to the kitchen waste discharge port 5b. A cylindrical bag holder 10 is fitted on the outside of the lower part of the garbage discharge tube 9. In this case, a magnet lla is provided on the back holder IO side, and on the other hand, a ferromagnetic ring llb that is magnetically attracted to it is provided on the garbage discharge tube 9 side, and the back holder IO It is detachably held on the kitchen waste discharge tube 9 side by a means. Note that instead of this magnetic attraction means, a bayonet type engaging means or a screwing means consisting of a male screw and a female screw may be used.

A garbage collection bag 8 made of, for example, a resin film is attached to the outer periphery of the bag holder IO using a suitable fastener such as a rubber band.

Next, the operation of this device will be explained. First, the opening of the garbage collection bag 8 is opened and the bag holder 10 is preferably positioned in the center thereof, and then the opening is narrowed and attached to the outer periphery of the bag holder 10 using, for example, a rubber band. Then, the lid 13a of the case body 13 is opened, the bag holder 10 is fitted to the lower part of the garbage discharge tube 9, and the bag holder 10 is held by the above-mentioned magnetic attraction means, and the lid 13a is closed. At this time, since almost no weight is applied to the case body 13, the case body 13 is attracted and held in its normal position, that is, the set position, by the magnet I6, and the microswitch 17 is turned on. Similarly, the microswitch 23 is also turned on.

When kitchen waste is inputted from the kitchen waste input port 2 and the screw 6 is rotated by the motor 7, the kitchen waste is cut into a size that can fit into the screw machine if it is large, and transported through the conveying pipe 5. After being drained, the garbage is discharged into the garbage collection bag 8 while being guided to the garbage discharge tube 9 from the garbage discharge port 5b. In this way, the garbage is discharged into the garbage collection bag 8 and its volume gradually increases, and when the pressing force against the lid 13a exceeds the holding force of the magnet 21, the lid 13a is opened. As a result, the microswitch 23 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 collection bag 8 is full. In this embodiment, if the weight of the garbage collection bag 8 exceeds a predetermined value before its volume, the case body 13 will tilt toward the front of the device around the hinge 14 against the attraction force of the magnet 16. , As a result, the microswitch 17 is turned off, and the motor 7 and the like are stopped in the same manner as above.

To replace the garbage collection bag 8, open the lid 13a, take out the bag holder 10, and replace the same bag holder l.
When the O is forcibly pulled out from the opening of the garbage collection bag 8 with the rubber band still attached, the opening of the garbage collection bag 8 is closed with the remaining rubber band. In this way, kitchen waste can be disposed of without getting one's hands dirty or causing unpleasant odors.

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

〔Effect of the invention〕

As explained above, according to the present invention, by opening the lid of the case body using the garbage collection bag, it is possible to reliably detect the accumulation of kitchen waste in the garbage collection bag based on its volume. , a kitchen waste processing device that is extremely user-friendly is provided.
