Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a front cover mounting structure of a rice milling machine.

[Conventional technology]

Traditionally, small rice milling machines used in general households have a rice milling mechanism installed in the upper part of the case, and a rice container and a bran container placed side by side in the lower part of the case, which can be accessed from the front.
Furthermore, a front cover that covers the front part of the rice milling machine is removably attached to the case at the top of both containers.

[Problem that the invention attempts to solve]

In the rice milling machine as described above, it is necessary to periodically perform maintenance to prevent clogging of the internal rice milling mechanism, and in that case, the front cover is removed.

However, in conventional rice milling machines, the front cover is attached with screws, and the screws are placed on the underside of the front cover so that they are not visible.
In addition to being difficult to attach and remove the screws, the screws protrude significantly downward to make them easier to operate by hand, causing problems such as getting in the way when putting in and taking out the rice case.

Therefore, this idea eliminates the screws on the front cover,
The purpose is to make it removable by using a fitting method.

[Means for solving problems]

In order to solve the above problems, this invention provides a rice milling machine in which a rice milling mechanism 2 is provided inside a case 1, and a front cover 3 that covers the front of the rice milling mechanism 2 is detachably attached to the front of the case 1. In the front cover mounting structure, a U-shaped bent part 6 consisting of a front part 4 and an inner side part 5 is provided on both sides of the front surface of the case 1, and a supporting piece is bent parallel to the front surface of the case at the inner end of the bent part 6. 7, and engagement holes 8 and 9 are provided in the inner surface portion 5 of the bent portion 6 and the support piece 7, respectively,
A U-shaped bent portion 10 that abuts the front surface portion 4 is provided on both side edges of the front cover 3, and an engaging piece 11 parallel to both side surfaces of the case is provided at the inner end of the bent portion 10. The structure includes a protrusion 12 that fits into the engagement hole 8 of the inner side surface 5 and a protrusion 13 that fits into the engagement hole 9 of the support piece 7.

[Effect]

When the front cover 3 is fitted to the front of the case 1, the U-shaped bent portion 10 of the front cover 3 comes into contact with the front of the U-shaped bent portion 6 of the case 1, and the front cover 3
The protrusions 13 of the protrusions 12 are connected to the engagement holes 8 and 9 of the case 1.
They fit into each other to prevent them from slipping out forward or moving downward.

〔Example〕

As shown in FIG. 1, the rice polishing machine has a rice polishing mechanism 2 inside a case 1 with an open front, and a rice container 15 and a bran container 16 with open tops at the bottom of the open end of the case 1.
are arranged side by side so that they can be taken in and taken out freely, and both containers 15,1
A front cover 3 that covers the front of the rice polishing mechanism 2 is removably attached above the rice polishing mechanism 6.

On both sides of the case 1 where the front cover 3 is attached,
As shown in FIG. 2, the inward U-shaped bent portion 6
is formed. The bent portion 6 consists of a front portion 4 bent at right angles to the side surface of the case 1, that is, along the front surface of the case 1, and an inner side portion 5 formed by bending the front portion 4 parallel to the side surface of the case. Also,
A support piece 7 is provided at the inner end of the inner side surface portion 5 and bent parallel to the front surface of the case.

A circular engagement hole 8 is provided in the inner side surface 5 of the bent portion 6.
is formed, and the support piece 7 is provided with a vertically long engagement hole 9. Note that the former engagement hole 8 may be a recess that is recessed in the direction of the side surface of the case 1.

Further, the front cover 3 has U-shaped bent portions 10 formed on both side edges. This U-shaped bent portion 10 may be curved into an arc as shown in the figure. This bent portion 10 is designed to come into contact with the front portion 4 of the bent portion 6 of the case 1;
It protrudes forward from the case 1 by the thickness of the bent portion 10.

In addition, a case 1 is provided at the inner end of the bent portion 10.
An engaging piece 11 is provided parallel to the side surface of. This engagement piece 11 is formed in a size that fits approximately into the inner surface of the inner side surface portion 5 .

This engagement piece 11 has a protrusion 12 projecting outward.
is formed and is adapted to be releasably engaged with the engagement hole 8. Further, a protruding piece 13 is formed on the inner edge of the engaging piece 11, and is adapted to engage with the lower end of the aforementioned engaging hole 9.

Note that an insertion piece 19 is formed at the upper end of the front cover 3 to be inserted into a groove 18 provided at the front edge of the upper panel 17 of the case 1. 20 in the figure is the lid of the rice input port.

The embodiment of this invention has the above-mentioned configuration, and when the insertion piece 19 of the front cover 3 is inserted and pushed into the groove 18 on the front edge of the case 1, the protrusion 12 fits into the engagement hole 8, and the front cover 3 Prevent slipping out to the front. Further, since the protruding piece 13 rests on the lower end of the engagement hole 9, the front cover 3 is prevented from moving downward. When removing the front cover 3, by pressing the bent portions 10 on both sides of the front cover slightly toward each other, the projections 12 will be disengaged from the engagement holes 8 due to the bending of the front cover 3. In this case, in order to allow the front cover 3 to bend, the engagement hole 9
The protruding pieces 13 are fitted with some margin in the left and right direction.

〔effect〕

As mentioned above, the front cover of this invention can be attached and removed by simply fitting it to the front of the case without using screws, so it has a good appearance and is easy to clean. This has the effect of making it easier to attach and detach when cleaning the mechanism.
