Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a rice polishing machine equipped with a polishing degree adjusting mechanism and a timer in addition to a rice polishing mechanism.

(Prior Art) Conventionally, in this type of rice milling machine, in addition to the rice milling mechanism,
There is provided a milling degree adjusting mechanism for arbitrarily setting the milling degree of brown rice milled by this milling mechanism and a timer for arbitrarily setting the length of milling time. Therefore, in this product, after inputting brown rice to the rice polishing mechanism, set the whitening degree adjustment mechanism to obtain the desired whitening degree, and then turn on the timer to adjust the rice polishing time according to the amount of brown rice. The desired rice polishing is performed by performing the setting operation so that the rice can be obtained.

(Problems to be solved by the invention) However, in the above-mentioned conventional one, the position of the time setting scale of the timer is determined in anticipation of the time until the brown rice is polished to the maximum whiteness, Therefore, as the milling degree is set to 7 minutes, 5 minutes, 3 minutes, and so on, in order to shorten the rice polishing time, the operating time of the timer becomes longer than the actual rice polishing time. In the case of 3 minutes, the time is 2 to 3 times as long as in the case of white rice, so the timer will perform unnecessary operation, which shortens the life of the timer unnecessarily and, as a user, There is a problem in that it is frustrating to wait until the operation is completed, or that it takes time to quickly rewind the timer to avoid it.

The present invention has been made in view of the above circumstances, and therefore an object thereof is to provide a whiteness adjusting mechanism,
The purpose of the present invention is to provide a rice-polishing machine that can make the difference between the actual rice-polishing time and the timer operating time small and substantially constant.

[Structure of the Invention] (Means for Solving Problems) A rice polishing machine of the present invention has a rice polishing mechanism, a whitening degree adjusting mechanism, and a timer, and adjusts the position of a time setting scale of the timer for the whitening degree. It is characterized in that it is linked to the setting operation of the mechanism and is changed substantially in proportion to it.

(Operation) According to the above means, the time setting of the timer is made larger as the whiteness of brown rice is raised, and the time setting of the timer is made smaller as the whitening degree of brown rice is lowered. Therefore, the difference between the actual rice polishing time and the timer operating time is small and becomes substantially constant.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

First, in FIG. 2, reference numeral 1 denotes an entire outer shell case, which is provided with a hopper 2 and a lid 3 for opening and closing the hopper 2 on an upper portion thereof. Reference numeral 4 denotes a rice polishing mechanism provided in series with the hopper 2, which is entirely in the case 1 and has a fixed rice polishing screen 5
And a motor 8 for rotating the rice-polishing screw (not shown) inserted in the rice-polishing screen 5 through a drive shaft 6, a belt transmission mechanism 7 and the like, and the hopper 2 Brown rice (also not shown) put in from the other side (left side in the figure)
While being sent to, the rice is screened by rubbing with the rice-polishing screen 5, the bran is dropped from the rice-polishing screen 5, and rice is dropped from the rice outlet 9 at the tip. In addition, 10 is a bran container for receiving and receiving rice as described above, and 11 is a rice container for receiving and storing rice,
As shown in FIG. 3, these are arranged side by side in the lower front part of the case 1 so that they can be pulled out forward.

On the other hand, 12 is a holding lid provided at the rice outlet 9 portion, which is provided with a closing force by giving a spring force of a spring 14 through a supporting plate 13 supporting the same, and thus the whitening of the brown rice, The feeding is performed against the closing force of the pressing lid 12. Reference numeral 15 is a spring retainer in contact with the spring 14, and 16 is a corrugated oblique side portion 17 shown in FIG. 1 for adjusting the pressure on the spring 14 via the spring retainer 15.
An operation plate having a, 18 is a slide operation lever extending forward from the operation plate 16, 19 is an operation knob attached to the tip (front end) of the slide operation lever 18, and 20 is a slide operation trajectory of the operation knob 19. A whiteness adjusting scale is provided along the front of the case 1 along with the whiteness adjusting mechanism.
Make up 21. Therefore, in the whiteness adjusting mechanism 21, the operation knob 19 is picked up and the operation plate 16 is moved to the whiteness setting scale 20.
The spring retainer can be
The contact position of the corrugated oblique side portion 17 of the operation plate 16 with respect to 15 is changed, thereby changing the pressing condition of the spring 14 via the spring retainer 15, the spring force generated by the spring 14 is changed, and the spring force is changed. As described above, the support plate 13
The holding lid 12 received via the can change its closing force. Therefore, the degree of retention of brown rice in the rice polishing screen 5 is changed, and the degree of whitening can be changed. In the present embodiment, in particular, the whiteness setting scale 20 has "white rice" indicating white rice, "7" indicating 7 minutes, "5" indicating 5 minutes, "3" indicating 3 minutes. Are displayed in order.

Next, 22 is a timer, and this is the above-mentioned whiteness adjusting mechanism.
It is arranged side by side with 21 in the upper front part of the case 1. or,
The timer 22 is a timer main body 23 having a mainspring, which is a drive source (not shown), a gantry mechanism linked to the spring, a contact for controlling the electric current to and from the motor 8 of the rice polishing mechanism 4, and the like. The pinion 25 attached to the timer shaft 24 protruding from the timer main body 23, the rack 26 engaged with the pinion 25, the slide operating lever 27 protruding from the rack 26, and the tip (front end) of the slide operating lever 27 attached. The operation knob 28 comprises a time setting scale 29 provided on the upper front surface of the case 1 along the slide operation trajectory of the operation knob 28. The operation knob 28 is grasped and the rack 26 is slid against the time setting scale 29. By operating
The time until the pinion 25 is rotated to wind the mainspring through the timer shaft 24 and the contact is turned off can be arbitrarily set. Thus, the time setting scale 29
Especially, in the case of the present embodiment, "5", "4", "3", "2", "1" (unit:
Display) are attached in order.

Reference numeral 30 denotes a spring which is installed from an appropriate fixed portion in the case 1 to the slide operation lever 18 of the whitening degree adjusting mechanism 21, to which time setting scales 29 of the timer 22 are attached at predetermined intervals.

Therefore, in the case of the above configuration, when the operation knob 19 is operated by operating the operation knob 19 so as to obtain a desired degree of whiteness for white rice, the spring 30 expands and contracts accordingly, and the timer 22 Time setting scale 29
Also, each position changes almost in proportion to that, for example, when the operation knob 19 is operated to the "white rice" side of the whiteness setting scale 20, the time setting scale 29 of the timer 22 is also set to the "white rice" side as a whole. When the operation knob 19 is moved to the "3" side of the refinement degree setting scale 20 while the respective intervals are widened, the time setting scale 29 of the timer 22 is moved to the "3" side as a whole. It changes so as to narrow each interval. Therefore,
If the whitening degree adjusting mechanism 21 is set to obtain a high whitening degree, in other words, if it is set so that it actually takes a long time to polish rice, the timer 22 also operates the operation knob 28 accordingly. When a long operating time is set, on the other hand, when the whitening degree adjusting mechanism 21 is set and operated to obtain a low whitening degree, in other words, when it is set and operated so as to actually require a short rice polishing time. Has a timer 22
As a result, a short operating time is set by operating the operating knob 28 less, and thus the difference between the actual rice-polishing time and the operating time of the timer can be made small and substantially constant. Therefore, it is possible to prevent the timer from operating unnecessarily for a long time, and thus, it is possible to prolong the life of the timer, and the waiting time until the operation of the timer 22 can be shortened so that the user is irritated. Further, it is possible to eliminate the need for a troublesome operation such as quick return of the timer 22 by the user's hand who cannot wait for it.

The present invention is not limited to the embodiment described above and shown in the drawings, and in particular, the specific structure for interlocking the time setting scale of the timer with the setting operation of the whitening degree adjusting mechanism, and the rice polishing mechanism and the whitening degree. The specific structure and other points of the adjusting mechanism may be changed as appropriate without departing from the scope of the invention.

[Effects of the Invention] As is clear from the above description, according to the rice polishing machine of the present invention, which has a rice polishing mechanism, a whitening degree adjusting mechanism and a timer, the position of the time setting scale of the timer is adjusted to Since the setting operation of the adjustment mechanism is interlocked with and changed substantially in proportion to it, the difference between the actual rice-polishing time and the operating time of the timer, which changes depending on the setting of the whitening degree, can be made small and substantially constant. This can prolong the life of the timer and eliminate user frustration.
In addition, various excellent effects can be obtained such that a troublesome operation can be eliminated if unnecessary.
