Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a water jet for the disposer that facilitates the crushing of food waste and prevents the food waste from adhering to the inner surface of the main body in a disposer that crushes and processes food waste. Regarding equipment.

[Conventional technology]

BACKGROUND ART Disposal of garbage generated during cooking and cleaning up in the kitchen is an extremely important issue from a hygienic standpoint as well as the generation of unpleasant odors. As a method for disposing of this raw garbage, a disposer has traditionally been used that pulverizes it into fine pieces and discharges them into a drain pipe.

However, since water containing food waste is discharged into the drain pipe, the degree of pollution in the wastewater increases, and suspended solids in the wastewater, B
OD (biochemical oxygen demand) and C0D (chemical oxygen demand) inevitably increase.

For this reason, types that are discharged together with water cannot be used in areas without complete sewage systems.

Against this background, instead of the structure in which garbage is discharged together with wastewater, a structure in which a certain amount of crushed raw garbage is packed into a polyethylene bag has become popular. As a disposer that performs this bagging, for example,
There is one described in Publication No. 1-195355.

This disposer puts food waste into a crusher that rotates at high speed, and sends the crushed food waste along with water to a squeezer.
The structure is such that solids and water are separated by centrifugation, and the solids are squeezed out and the processed product is packed into bags.

[Problem that the invention seeks to solve]

In conventional crushers, garbage is crushed between a fixed outer blade and a rotating inner blade. In the conventional system, a gap is provided in the drainage part of the sink for water to flow, and water is supplied from the tap to the garbage being crushed. The supplied water freely falls into the grinding chamber and washes away food waste adhering to the inner surface of the grinding chamber. From this point on, a large amount of water is required to clean the inner surfaces of the grinding chamber. However, since the amount of water supplied is adjusted by the person using the disposer, there is a tendency to supply excessive water to ensure sufficient cleaning.

In addition, it is necessary to open and close the faucet for cleaning, which tends to be disliked by users.

Therefore, an object of the present invention is to make the use of a disposer more convenient by automating the water supply for washing away garbage adhering to the inner surface of the grinding chamber.

[Means for Solving the Problems] In order to achieve the above-mentioned objectives, the water injection device for a disposer of the present invention includes a crushing mechanism for crushing food waste and a centrifugal separation of the crushed food waste into solids and moisture. In a disposer having a mortar-shaped dewatering rotor inside the main body, a nozzle is provided that opens on the wall surface of the upper part of the main body above the crushing mechanism, and a solenoid valve that is automatically opened and closed is provided in the water supply conduit leading to the nozzle. It is characterized by:

〔Example〕

Hereinafter, the features of the present invention will be specifically explained using examples with reference to the drawings.

The disposer is placed on the bottom plate of the cabinet, the upper end is connected to the sink drain, and almost the entire disposer is housed in the casing. The casing consists of a full-height main chamber and side chambers flanking the main chamber.

A garbage crushing mechanism and a dewatering mechanism are provided in the main chamber. On the other hand, the sub-chamber is provided with a pack mechanism for bagging crushed and dehydrated garbage and a container storage section for sterilization and deodorization.

Figure 1 shows the interior of this main chamber.

The upper body part 1 of the disposer is connected to the outlet 2 of the sink. At the connection part between the upper part 1 of the main body and the discharge port 2, a ring 3 is formed so that a large diameter opening is formed in the center part.
A rubber cover 4 is provided to cover the opening in the ring 3. This cover 4 is provided with a plurality of radial slits (not shown) extending radially from the center, and is opened by the weight of the garbage thrown in from above, and when the garbage passes through it, it opens again as shown in the figure. close. Note that when the disposer is not in use, the sink lid 5 is placed over the cover 4.

A crushing tooth 6 for crushing garbage is formed on the inner periphery of the lower part of the upper part 1 of the main body, and a rotating plate 9 centered on the output shaft 8 of a drive motor 7 is attached to the inner periphery of the crushing tooth 6. It is being This rotary plate 9 has crusher teeth 1
0 is attached, and the input garbage is crushed between the crusher teeth 10 and the crushing teeth 6. The crushed garbage is guided into the dewatering rotor 12 by a guide 15 having a shape corresponding to the inclined surface inside the dewatering rotor 12.

A dewatering rotor 12 is disposed inside the lower part 11 of the main body to dehydrate the crushed garbage by centrifugal force. When the dewatering rotor 12 is rotated at high speed by the drive motor 7, the water contained in the food waste is transferred to the outside of the dehydrating rotor 12 by centrifugal force through a large number of slits 13 or small holes provided in the wall of the dehydrating rotor 12. and is discharged to the outside of the disposer via the drain pipe 14. On the other hand, the dehydrated food waste, that is, the solid content, moves up the inclined surface of the dewatering rotor 12 by centrifugal force, and passes through the opening 1 provided at the upper end of the dewatering rotor 12.
2 a and a discharge port 17 opened on the inner surface of the lower part 11 of the main body, and is discharged into a bend 18 . In addition, 16 is an annular projection provided in the inner chamber of the lower part 11 of the main body, and the dehydration rotor 12
It is located below the flange of the

In such a disposer, a water jet nozzle 2o is arranged above the crushing section. A solenoid valve 19 and a pressure reducing valve 22 are provided in the water supply conduit 21 leading to the water injection nozzle 20. The flow rate of water sent into the upper part 1 of the main body is adjusted by reducing the secondary pressure to a certain range using a pressure reducing valve 22.
This is done by changing the opening/closing time of the solenoid valve 19.

The operations of the pressure reducing valve 22 and the solenoid valve 19 are controlled based on specifications programmed in advance.

FIG. 2 shows a state in which the water injection nozzle 20 is opened inside the upper part 1 of the main body. Also, Figure 3 is Figure 2 I-1
The line sectional view, FIG. 4, is a horizontal sectional view taken along a plane including the water injection nozzle 20.

The water injection nozzle 20 has a cylindrical shape with a closed end, and a nozzle opening 23 is bored in the corner thereof. Therefore, the water injected from the water injection nozzle 20 spreads in the circumferential direction on the inner surface of the main body upper part 1 as shown in FIG.
As shown in the figure, it flows spirally along the inner surface of the upper part 1 of the main body. Therefore, the inner surface of the upper part 1 of the main body is washed over a wide area, and the garbage adhering thereto is washed away. Further, it is preferable that the nozzle ports 23 are provided in the same direction as the rotation direction of the rotating plate 9 by the drive motor 7. As a result, the water jetted from the water jet nozzle 20 rotates inside the main body upper part 1 together with the garbage.

Here, the nozzle opening 23 is preferably designed so that the spray angle θ of the water jetted from the water jet nozzle 20 is 60 to 150 degrees. When this spray angle θ is less than 60 degrees, the area of the inner surface of the main body upper part 1 to be cleaned becomes small;
A sufficient cleaning effect cannot be obtained.

On the other hand, if the spray angle θ exceeds 150 degrees, it becomes necessary to increase the pressure of the washing water excessively in order to wash away the garbage adhering to the inner surface.

Next, the operation of this disposer will be explained.

First, the sink lid 5 is removed and garbage is thrown into the upper part 1 of the main body from above the cover 4. Then, close the sink lid 5, turn on the power (not shown) and drive the drive motor 7.
The output shaft 81 rotates the rotating plate 9 and the dewatering rotor 12. The garbage is crushed between the crushing teeth 6 and the crusher teeth 10. About 10 seconds after starting rotation, the solenoid valve 19
is opened, and water is supplied from the water injection nozzle 20 to the inside of the upper part 1 of the main body. This supplied water first cleans the inner surface of the upper part 1 of the main body, and then is sent between the crushing teeth 6 and the rotary plate 9 together with garbage. With this water supply, food waste is easily crushed. After sending the crushed garbage to the dewatering rotor 12 and cleaning the inner surface of the upper part 1 of the main body, the solenoid valve 19 is closed to stop water supply.

The crushed garbage is sent to the rotating dewatering rotor 12 along the inner wall of the guide 15 together with the supplied water. Here, since the dewatering rotor 12 is rotating at high speed, the moisture contained in the garbage is discharged from the drain pipe 14 through the slit 13 or the small hole.

The dehydrated food waste, that is, the solid content, is transferred to a dewatering rotor 12.
receives centrifugal force due to the rotation of the dewatering rotor 12, rises along the inclined inner surface of the dewatering rotor 12, and exits the discharge port 1 from the opening 12a at the upper end.
7 and then sent to bend 18.

〔Effect of the invention〕

As explained above, in the present invention, the inner surface of the upper part of the main body into which garbage is thrown is cleaned with water sprayed from a water spray nozzle whose water supply amount is automatically adjusted, and this water is transferred to the crusher. is being sent to. Therefore, the inner surface of the upper part of the main body is always kept free of food waste, and moreover, the food waste can be easily crushed in the crushing section. Since the amount of water supplied is automatically adjusted, the user does not have to worry about it, unlike conventional disposers. Furthermore, since the flow rate can be set to the minimum required for cleaning the inner surface, water can also be saved.
