Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an electric juicer for squeezing juice from vegetables, fruits, etc.

Conventional technology Conventionally, the length of engagement between the output shaft that transmits the rotation of the electric motor of this type of juicer and the centrifugal separation cage that is removably fitted to this output shaft is smaller than the gap between the centrifuge and the lid. It was.

Problems to be Solved by the Invention For this reason, when an abnormal imbalance is applied to the centrifugal separation cage, the centrifugal separation cage may float up, and the output shaft and the centrifugal separation cage may become disengaged. If the rotation stopper comes uncoupled, the output shaft and centrifugal cage will rotate, and in some cases, such as when both are made of resin, the output shaft and centrifugal cage may become stuck or the rotation stopper may become uncoupled. The instantaneous centrifuge cage was suddenly pushed upwards, and the top surface of the centrifuge cage sometimes hit the lid top surface hard. If the centrifugal separation basket strongly hits the lid, the lid will come off and the centrifugal separation basket will fly away from the main body, which is dangerous to humans. Therefore, the lid must be firmly fixed to the main body, etc., and it takes considerable force to attach and remove the lid. There was a problem.

Means for Solving the Problems Therefore, in order to solve the above problems, the technical means of the present invention is to reduce the length of the fitting part between the output shaft that transmits the rotation of the electric motor and the fitting part of the centrifugal separation cage. It is made larger than the gap between the separating basket and the lid.

Effect The effect of this technical means is as follows. In other words, because the length of the engagement between the output shaft and the rotation stopper of the centrifugal separation cage is larger than the gap between the centrifugal separation cage and the lid, the centrifugal separation cage may float up for some reason and come into contact with the lid. Even if the output shaft and centrifugal separation cage are rotated, the output shaft and centrifugal separation cage will not rotate because the rotation stopper is fitted.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 to 5, reference numeral 1 denotes a motor, which is attached to a main body 2 together with a back plate 5 with screws 4 via a buffer 3. Reference numeral 6 denotes an output shaft connected to the rotating shaft of the motor 1, and a convex output rotation prevention portion 7 is formed on the side surface of the output shaft. A substantially cylindrical centrifugal separation cage 8 is removably attached above the output shaft 6, and a fitting portion 9 of the centrifugal separation cage 8 comes into contact with an output rotation stopper portion 7 of the output shaft 6. A convex transmission detent portion 10 that receives rotational force is formed. In addition, a cutter 1 is installed at the center bottom of the centrifugal separation basket 8.
1 is provided, and a comb-shaped filter 12 is provided on the inner surface.
is provided. 13 is a container that covers the centrifuge cage 8 and is mounted on the main body 2; 14 is a container 1;
It is a lid that covers 3. In addition, the cutter 11 is attached to the lid 14.
A material input port 15 is provided adjacent to the material input port 15. A push rod 16 is slidably provided in the material input port 15 and presses the material against the cutter 11. 17
is a clamp for fixing the lid 14 attached to the main body 2, and has a fixing part 19 that fits into a hole 18 provided in the lid 14. 20 is a spring that presses the clamp 17 outward.

Next, the operation of the configuration of this embodiment will be explained. First, the container 13 is placed on the main body 2, and then the centrifugal separation basket 8 equipped with the filter 12 is fitted onto the output shaft 6, and then the container 13 is strongly pressed toward the main body 2 while covering the opening of the container 13 with the lid 14. Then clamp 1
The fixing part 19 of 7 is pressed below the lid 14 and is once attached to the main body 2.
Although the hole 18 of the lid 14 is displaced inward, the fixing part 19
When the clamp 17 is pressed outward by the spring 20, the fixing part 19 fits into the hole 18, and the lid 14 is fixed to the main body 2. In this state, when the switch leading to the motor 1 is turned on, the motor 1 rotates, the rotation is transmitted to the output shaft 6, and the centrifugal separation basket 8 is rotated. While the centrifugal separation basket 8 is rotating, cutting material is introduced from the upper surface of the input port 15 and pressed against the cutter 11 with the push rod 16, whereby the material is cut and the cutting material is collected in the filter 12. Then, due to the centrifugal force, the distilled material in the filter 12 passes through the comb-shaped filter 12, passes between the centrifugal cage 8 and the filter 12, and flows out from the upper surface of the centrifugal cage 8 into the container 13.

Here, the rotation transmission between the output shaft 6 and the centrifugal separation cage 8 is carried out when the output rotation prevention portion 7 of the output shaft 6 is connected to the centrifugal separation cage 8.
This is done by contacting the transmission detent 10 provided on the fitting portion 9 of the. The mating length H of both
The gap h between the part, the top surface of the centrifugal separation basket 8, and the lid 14
Since H>h, the centrifugal separation cage 8 does not come into contact with the lid 14 after the centrifugal separation cage 8 and the output shaft 6 come out of the rotation stopper. Therefore, lid 1
Since the fitting part 9 of the centrifugal separation cage 8 and the fitting part of the output shaft 6 do not rotate unless the centrifugal cage 8 and the output shaft 4 come off, they will not be stuck together even if they are made of resin. On the other hand, h<
In the case H, it goes without saying that the locking portions of both the centrifuge cages 8 and 14 are disengaged from each other before the centrifugal separation basket 8 comes into contact with the lid 14. In addition, when fitting the centrifugal separation basket 8 to the output shaft 6, the top and bottom of the detents of both of them are shaped into a triangular shape so that the top and bottom of the detents of both come into contact and the fitting is not incomplete and the fitting is smooth. However, in this way, if the two rotation prevention parts become disengaged, the triangular taper part of the output rotation prevention part 7 of the output shaft 6 will be formed as shown in FIG. 21 and the triangular tapered part 22 of the transmission rotation stopper part 9 of the centrifugal separation cage 8
Since the centrifugal separation basket 8 is pushed upward, the lid 14
If it is not firmly fixed with the clamp 17, the lid 14 may come off and the centrifuge cage 8 may fly away from the main body 2, causing harm to the human body, but if H > h, the centrifuge cage 8 will float upward. The force itself is weak because the force that tends to loosen is only the upward component of the centrifugal force that occurs when the centrifugal separation basket 8 rotates. Therefore, even if the fixation of the lid 14 with the clamp 17 is weakened, the centrifugal separation basket 8
There is no possibility that the lid 14 will be unfixed and the lid will be pushed up and scattered. Therefore, the fixation of the lid 14 itself can be weakened, and the lid 14 can be easily attached and detached with a weak force. In addition, when a viewing window 23 is provided on a part of the top surface of the lid 14, when the filter 12 is full of dregs from the cuttings and the dregs are ejected upward, the gap between the top surface of the centrifugal separation basket 8 and the lid 14 is small. Therefore, the ejected lees easily adhere to the viewing window 23, and it can be easily determined from the outside whether the filter 12 is full of lees.

Effects of the Invention The present invention can reduce the fitting length between the output shaft and the centrifugal cage.
Since the gap is larger than the gap between the centrifugal separation basket and the lid, it prevents the centrifugal separation basket and the output shaft from coming uncoupled from each other and causing both to rotate and become stuck together, and also prevents the centrifugal separation basket from moving upward. Since the force that causes it to float is weak, the centrifugal separation cage does not push up the lid and scatter upwards. Furthermore, since the lid can be fixed with a weak force, the lid can be easily attached and detached, which is extremely effective.
