Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kitchen waste disposal machine having an opening / closing lid for processing kitchen waste such as household garbage.

[0002]

2. Description of the Related Art A conventional garbage disposal of this type is generally equipped with various functional parts inside a lid which is opened and closed. The hinge part has a strong structure to support the weight, and a special stay is provided on the hinge part so that the closure of the garbage disposal part is not impaired due to distortion or inclination when the lid is opened or closed.

[0003]

However, in the structure of such a conventional garbage disposal machine, the hinge portion itself is made to have a considerably strong structure in order to prevent the inclination and the like when the lid is opened and closed, and the hinge portion is further provided with a stay or the like. It was necessary to provide a separate stiffener. Therefore, the hinge part becomes too large, or if a stay etc. is provided, a hole through which the stay passes will be formed and the structure will have to be waterproof again.Since the lid is heavy, it is easy for the lid to close easily and your hands are caught. There was a problem such as getting injured.

The present invention solves the above problems by making the hinge portion of the lid relatively small in space, and stably opening and closing the lid without using a reinforcing tool such as a stay. It is an object of the present invention to provide a kitchen waste disposal machine that does not have a risk of softening the shock when opened or naturally closing and getting your hands caught.

[0005]

In order to achieve the above-mentioned object, the present invention has a lid body having a packing for sealing the garbage disposal portion, and a hinge for opening and closing the lid body located at the rear portion of the lid body. It has a U-shaped hinge formed by extending substantially parallel side walls penetrating the shaft, and a wall that slidably fits the side wall of the hinge and supports both ends of the hinge shaft. A U-shaped hinge receiver, a pin provided behind the hinge shaft in parallel with the hinge shaft and penetrating the side wall of the hinge, and on the wall of the hinge receiver at a position corresponding to the movement trajectory of the pin. The slit formed so that the tip of the pin fits and slides freely, the protrusion provided on the side wall of the hinge so that the tip projects from the inner wall of the slit, and the tip of the pin A spring that is attached and biases the pin downward. Then, when the lid is opened and closed, the pin reciprocally slides along the slit, and when the lid is fully opened, the convex portion urges the wall of the hinge receiver from the lower end of the slit to get over the wall. It was done like this.

[0006]

According to the present invention having the above-described structure, the hinge that rotates together with the lid and the hinge receiver that pivotally supports the hinge are formed in a U shape, and the side wall of the hinge slides on the inner wall of the hinge receiver to rotate. Moreover, since the hinge shaft and the end portion of the pin provided rearward are slidably rotated in the slit, the hinge and the hinge receiver are pivotally supported in a close contact state when the lid body is opened and closed. Tilt can be prevented. Further, since the spring is attached to the pin and the pin is urged downward, the lid can be opened with a light force when the lid is opened, and the lid can be lightly closed because the weight of the lid is reduced when the lid is closed. In addition, a protrusion is provided on the side wall of the hinge to make a click action with the hinge receiver when the lid is fully opened, so the impact at full opening is softened and it is prevented from naturally closing due to recoil at the time of front opening. can do.

EXAMPLES Examples of the present invention will be described below with reference to FIGS.
This will be described with reference to FIG.

In FIG. 1, reference numeral 1 is a heat insulating container, which has a food waste container 2 which is installed in the heat insulating container 1 so as to be freely taken out. A rotary blade 3 is provided in the raw garbage container 2 as a means for crushing and stirring raw garbage. The rotary blade 3 is provided on the inner bottom portion of the food waste storage container 2 and is fixed to the rotary shaft 4 protruding from the bottom surface of the food waste storage container 2. Above the food waste container 2, there are a heater 5 as a food heating means, a fan 6 for evenly feeding the heat of the heater 5 into the food waste container 2, and a lid 8 having a fan motor 7 incorporated therein. It is provided. A condenser section 9 for condensing water vapor generated from food waste is arranged on the outer peripheral portion of the heat insulating container 1, and a blower fan 10 for cooling the outer surface of the condenser section 9 is installed outside the condenser section 9. The rotation of the rotary blade 3 is driven by a drive motor 12 built in the main body 11 of the garbage processing machine through a speed reducing means 13 such as a belt. Reference numeral 14 denotes a condensed water container for receiving condensed water, which is detachably attached to the lower portion of the garbage processing machine body 11.

The lid 8 has a hinge 15 having a U-shaped metal plate at the rear portion, and is openable and closable via a hinge receiver 16 and a hinge shaft 17 provided on the main body 11 of the garbage processing machine. Reference numeral 18 is a cover that covers these hinge portions. As shown in FIGS. 2A and 2B, the hinge 15 has a U-shaped wall 19 extending rearward to form a side wall 20 having a substantially hook-shaped side surface. The hinge shaft 17 is rotatably pierced through the front portion of the side wall 20, and both ends thereof are axially supported by both walls 21 of a hinge receiver 16 formed in a U shape that slidably inscribes the outer surface of the side wall 20. ing. Further, on the side wall 20 behind the hinge shaft 17, there is provided a pin 22 penetrating the hinge shaft 17 in parallel therewith. Further, on both walls 21 of the hinge receiver 16, arc-shaped slits formed so that when the pin 22 moves by the rotation of the hinge 15, the end portion of the pin 22 fits and slides in a portion corresponding to the movement. Has 23. A coil-shaped open / close spring 25 is suspended at one end of the pin 22 to urge the pin 22 downward. Further, as shown in FIG. 3, on the surface of the side wall 20 corresponding to the slit 23, there is provided a convex portion 24 formed so that the tip portion projects from the inner wall of the slit 23,
When the lid 8 is opened and closed, the convex portion 24 is shown in FIG.
As shown by the chain double-dashed line in (b), the end of the slit 23 is abutted, and when further opened, the elasticity of the side wall 20 is used to urge the inner surfaces of the two walls 21 from the end of the slit 23 to overcome the ends of both walls. I am trying to make a so-called click action that stops.

The operation of the garbage processing machine configured as described above will be described. The raw garbage put in the raw garbage storage container 2 is crushed by the rotary blade 3 whose rotation direction is reversed. At the same time, it is heated by the heater 5, and the fan 6 evenly diffuses the heat into the food waste container 2. Water vapor containing odorous components is generated from raw garbage, and flows into the condensation section 9 outside the heat insulating container 1 through the opening of the raw garbage container 2. Then, the steam is blown by the blower fan 10 in the condenser 9.
It is cooled by, condensed, and collected in the condensed water container 14. In order to prevent the odor during processing from escaping to the outside of the main body during these series of operation processes, the packing 26 and the lid 8 are sealed. And the lid 8
When opening, the lid 8 is opened by the force of the opening / closing spring 25 by removing the latch type handle (not shown) at the front of the lid. At this time, a hinge 15 that rotates together with the lid body 8 and a hinge receiver 16 that pivotally supports the lid body 8 are formed in a U-shape, and a side wall 20 of the hinge 15 is slidably rotated on an inner wall of the hinge receiver 16 and a hinge shaft is provided. Since the end portion of the pin 22 provided at a distance from the rear portion 17 is slidably rotated in the slit 23, the hinge 15 and the hinge receiver 16 are pivotally supported in a close contact state when the lid 8 is opened and closed. The inclination of the lid 8 can be prevented.

Further, since an opening / closing spring 25 is attached to the pin 22 and the pin 22 is biased downward, it can be opened with a light force when the lid 8 is opened, and the weight of the lid 8 is lightened when the lid 8 is closed, so that the lid is lightly lidded. The body 8 can be closed. Further, when the lid 8 is opened, when the convex portion 22 passes through both wall portions of the hinge receiver 16 without the slit 23 in front of the fully open position, the biasing resistance softens the impact at the time of rotation, and further the hinge receiver 16 After passing through both the walls 21, the convex portion 24 returns to the original state and the protruding portion has a locking action, so that the lid body 8 can be prevented from being closed naturally.

[0012]

As is apparent from the above description, according to the present invention, the hinge that rotates together with the lid and the hinge receiver that pivotally supports the hinge are formed in a U shape, and the side wall of the hinge slides on the inner wall of the hinge receiver. The hinge and the hinge receiver are in close contact with each other when the lid is opened and closed because the end of the pin that is moved and rotated and separated from the hinge shaft behind is slid in the slit. The lid can be pivotally supported to prevent the lid from tilting, the hinge portion can be made into a relatively small space, and the lid can be stably opened and closed without using a reinforcing member such as a stay. Further, since the spring is attached to the pin and the pin is urged downward, the lid can be opened with a light force when the lid is opened, and the lid can be lightly closed because the weight of the lid is reduced when the lid is closed. In addition, a protrusion is provided on the side wall of the hinge to make a click action with the hinge receiver when the lid is fully opened, so the impact at the time of full opening can be softened, or it can close naturally due to recoil at the time of full opening. The risk of being caught is eliminated.
