Description

[Detailed description of the invention] [Field of industrial application] This invention relates to an improvement of a measuring rice bin with a cleaning window.

[Conventional technology]

Recently, there is a tendency for measuring rice jugs to be installed inside kitchen cabinets so that they cannot be taken out or removed, or to be integrated with storage shelves. In this type of weighing rice bin, the top plate of the rice storage chamber is always closed, and the top plate must be removed to clean or inspect the inside of the rice storage chamber, just like in a normal weighing rice bin. I can't.

Therefore, as a prior art related to this point, a special cleaning window is provided on the front wall or side wall of the rice storage chamber, and this cleaning window can be opened and closed with a cover plate, as disclosed in Japanese Utility Model Application No. 59-188039. It is. Incidentally, grain insects (rice-eating insects) often become active and breed inside the rice bin, and rice bran tends to adhere to the inside of the rice bin, so it is necessary to clean it regularly to store and preserve cooked rice hygienically. In addition, the discharge port at the bottom of the rice jug may become clogged or malfunction in the metering operation, so inspection and cleaning are necessary from this point of view as well.

[Problem that the invention attempts to solve]

However, in the conventional cleaning window, a gap tends to form between the opening edge of the cleaning window and the mating surface of the lid plate, and rice grains tend to get stuck or get caught in this gap. In particular, the cleaning window has an opening as wide as possible to make it easy to put the hand in and take it out, and the lid plate that closes this wide window needs to be lightweight and easy to handle, so it is generally made of a plastic molded product. In such a case, the lid plate was likely to flex and deform by expanding outward due to the pressing force of the rice stacked in the rice storage chamber, and this deformation tended to create a gap between the mating surface between the opening edge of the window and the lid. .

In this way, a gap is created between the mating surfaces of the inner surface of the lid plate and the opening edge of the cleaning window, and if rice grains get stuck or get stuck in this gap, it is difficult to open the lid plate when cleaning or inspecting the rice storage chamber. Sometimes rice grains would fall around the outside of the rice bin and scatter, making cleaning up difficult. In addition, if rice grains get caught on the edge of the window opening, it may cause trouble in the smooth opening and closing operation of the lid plate.

In order to solve this problem, this invention eliminates the phenomenon of rice grains clogging or getting stuck in the cleaning window, especially between the lower edge of the opening and the mating surface of the window plate, thereby preventing the rice grains from scattering, and preventing the lid plate from scattering. The purpose is to facilitate smooth opening and closing operations.

[Means for solving problems]

The present invention has a cleaning window 21 opened in the rice storage chamber 9 portion of the front wall 7 of the main body box 1, and a lid plate 2 that opens and closes the cleaning window 21 on the outer surface of the front wall 7.
We assume a measuring rice bin equipped with 2. Thus, the opening lower edge 21d of the cleaning window 21 and the cover plate 22
A gap cover piece 47 protruding from the inner surface of the lid plate 22 between the mating surfaces and above the opening lower edge 21d.
The gap covering piece 47 is sloped downward toward the inside of the rice storage chamber 9.

Here, the gap covering piece 47 may be formed integrally with the cover plate 22 or may be formed separately and attached to the cover plate 22 as desired.

[Effect]

According to the above configuration, even when rice is stored in the rice storage chamber 9 up to the height of the lid plate 22, the presence of the gap covering piece 47 allows the rice to spread between the lid plate 22 and the opening lower edge 21d of the cleaning window 21. There will be no intrusion between the mating surfaces. In addition, the gap cover piece 47
Even if the rice is placed on top, the rice naturally slides down inside the rice storage chamber 9 along the slope provided thereon, so that when the lid plate 22 is opened, there is no chance of the rice spilling out of the rice bin.

〔Example〕

Hereinafter, one embodiment of a measuring rice bin with a cleaning window according to this invention will be described based on the drawings.

In Fig. 2, the proposed measuring rice jug has a storage shelf 2 integrally set on the right side of the main body box 1 for storing electric cooking utensils such as a rice cooker and toaster, small kitchen items, etc. 1 and the top plate 3 is fixed to the upper side of the storage shelf 2,
A microwave etc. can be placed on top of this.

The rear wall 6 is made of steel plate, and the front wall 7 is made of a plastic panel.

The internal space of the main body box 1 is divided into upper and lower parts by a funnel 8, forming a rice storage chamber 9 on the upper side and a measuring and dispensing chamber 10 on the lower side. The top of the rice storage chamber 9 is covered with the top plate 3 fixed thereto, and the bottom of the weighing and dispensing chamber 10 is covered with a bottom plate 11.

At the top of the front wall 7, a rice inlet 12 formed in a funnel shape separate from the front wall 7 has two positions: a position A in which it protrudes outward from the front, and a position B in which it is stored flush with the front. It is rotatably mounted around a shaft 13, and rice can be thrown into the rice storage chamber 9 in its protruding position A.

As is well known, the weighing and dispensing chamber 10 is equipped with a measuring device 14 and a shutter 15 at the lower end outlet of the funnel 8. By pressing down an operating lever 16 arranged to face the lower part of the front wall 7, the shutter 15 can be opened.
is opened, and the metered amount of rice in the scale 14 is dropped into a tray 17 that is housed in an opening in the front wall 7 below the lever 16 and can be freely pulled out.

A cleaning window 20 is provided on the front side of the main body box 1. This cleaning window 20 has a rectangular cleaning window 21 opened at a position facing the rice storage chamber 9 on the front wall 7, and this cleaning window 21 is opened and closed with a cover plate 22.

In FIGS. 1 and 6, the cover plate 22 is a plastic molded product separate from the front wall 7, and is formed into a rectangular shape one size larger than the opening size of the cleaning window 21. Therefore, when the cover plate 22 is placed on the outer surface of the front wall 7 to close the cleaning window 21, the entire circumference of the cover plate 22 overlaps the outer surface of the entire circumference of the cleaning window 21 on the front wall 7.

Further, the lid plate 22 has a reinforcing rib 23 in the shape of a front gate on its inner surface to have sufficient strength to withstand the pressure of rice in the rice storage chamber 9. A groove 24 corresponding to the rib 23 is formed on the outer surface of the front wall 7 to form a cleaning window 2.
The lid plate 22 is recessed along the upper opening edge 21a, the left opening edge 21b, and the right opening edge 21c of
When closed, the rib 23 fits into the groove 24, and the rib 23 and the opening edges 21a, 21b,
21c is polymerized.

The cleaning window 21 is opened and closed by attaching and detaching the cover plate 22 to the front wall 7.
The attachment/detachment mechanism of No. 2 is constructed as follows.

1 and 6, a pair of left and right connecting claws 25, 25 are provided at the lower end of the cover plate 22 to protrude downward, while a lower edge 21 of the opening of the cleaning window 21 of the front wall 7
A step portion 26 for receiving the lower edge of the cover plate 22 is formed on the outer surface below d in a shape projecting slightly forward, and a pair of left and right joint holes 27, 27 are provided in the step portion 26, and a pair of left and right joint holes 27, 27 are provided in this step portion 26 to receive the lower edge of the cover plate 22. The joint claws 25, 25 can be freely inserted and removed. The joint hole 27 passes through the front wall 7 in both the inside and outside directions, and is located below and outside the upper flange 8a of the funnel 8, which extends to the inside of the lower edge 21d of the opening. In other words, since the joint hole 27 and the rice storage chamber 9 are blocked by the funnel 8,
If rice grains in the rice storage chamber 9 get stuck in the joint hole 27,
Nothing will spill out from here.

A locking means is provided between the upper end of the lid plate 22 and the overlapping surface of the front wall 7 so that the upper end of the lid plate 22 can be reliably locked to the front wall 7 in the closed state.

As shown in FIGS. 4 to 6, so-called blank locks are used as the locking means, and a pair of left and right latches 30 are installed above the cleaning window 21 on the front wall 7 side, and a pair of latches 30 on the side of the cover plate 22 are used. It consists of a latch receiving piece 31 attached on the inner surface of the upper end. Latch 3
0 is provided protruding forward from the left and right ends of a swinging metal fitting 33 attached to the inner surface of the front wall 7 so as to be swingable around a shaft 32, and facing into each of the left and right holes 34 of the front wall 7. . Also, the latches 30, 3 on the swinging metal fitting 33
A release operating lever 37 is provided protruding from an intermediate portion between 0 and 0, and the tip of the lever 37 protrudes forward from a hole 34 in the front wall 7. This swinging metal fitting with latch 3
3 is attached to the inner surface of the front wall 7 so as to cover it with a cover 35, and a spring 36 is wound around the shaft 32.
A rotational force is applied so that the latch 30 always swings downward.

On the other hand, the latch receiving piece 31 is fixed with a screw 38 so as to protrude rearward from the upper end of the inner surface of the cover plate 22, and the latch 30 is attached to the tip of the latch receiving piece 31.
A hole 39 is formed for engaging and disengaging the claw 30a at the tip of the holder. The tip of the release lever 37 faces a recess 40 provided at the center of the upper end of the cover plate 22 in the left-right direction, as shown in FIG.

By pulling it out upwardly, the cover plate 22 is completely removed from the front wall 7, and the cleaning window 21 can be opened.

The operating lever 37 is hidden by a cap 41 to prevent the cover plate 22 from being accidentally opened by a child. That is, as shown in FIG. 1, the cap 41 is fitted into the recess 40 of the cover plate 22, and the cap 41 is retracted substantially flush with the outer surface of the cover plate 22 to hide the release operation lever 37. It is rotatably supported around a shaft 42 in a position D in which it protrudes forward from the outer surface of 22 and opens a recess 40 . In this protruding position D, the cap 41 also serves as a handle when the lid plate 22 is opened and closed.

Now, the gap covering piece 47, which is a feature of the present invention, will be explained based on FIGS. 1 and 6.
A gap cover piece 47 is provided at the lower part of the inner surface of the cover plate 22 in the left-right direction, and when the cover plate 22 is closed, the cover piece 47 aligns the inner surface of the cover plate 22 with the lower edge 21d of the opening of the cleaning window 21. between the surfaces and the lower edge 2 of the opening
The upper part of the opening 1d is covered to prevent rice grains from entering between the mating surfaces or staying on the lower edge 21d of the opening. Further, the gap cover piece 47 is sloped downward toward the funnel 8 so that even if rice grains are placed on it, it will naturally slide down towards the funnel 8.

The illustrated gap cover piece 47 is formed integrally with a downward slope from the lower end of a plastic transparent window plate 48 for visually checking the remaining amount of rice, thereby simplifying its attachment. The transparent window plate 48 for visually checking the remaining amount of rice is the lid plate 22
It is fitted from the inner surface of the cover plate 22 into a viewing window 49 opened at the lower part of the cover plate 22, and the overlapping surfaces with the inner surface of the cover plate 22 are integrally joined by welding or adhesive means. At the same time as the window plate 48 is joined, the cover piece 47 is attached to the inner surface of the cover plate 22.

[Effect of idea]

As explained above, according to the measuring rice bin with a cleaning window of the present invention, the cleaning window 21 is located in the main body box 1.
Since the front wall 7 of the rice storage chamber 9 is opened in the rice storage chamber 9 portion, the inside of the rice storage chamber 9 can be easily cleaned and inspected by operating the front surface.

Particularly, in the present invention, the gap covering piece 47 is formed from the inner surface of the lid plate 22 that opens and closes the cleaning window 21.
The inner surface of the cleaning window 21 and the opening lower edge 21d of the cleaning window 21 are provided with a downwardly sloping protrusion toward the inside of the rice storage chamber 9 so as to cover the area between the mating surfaces and the upper part of the opening lower edge 21d. It is possible to reliably prevent rice grains from entering or clogging between the inner surface of the lid plate 22 and the lower opening edge 21d of the cleaning window 21. Therefore, there is an advantage that the lid plate 22 can be opened and closed smoothly, and that rice grains are not scattered outside the rice bin when the lid plate 22 is opened.
