Description

FOOD PROCESSOR

BACKGROUND OF THE INVENTION

This invention relates to a food processor, 5 particularly to one having both functions of a juicer and a food blender.

A previously-proposed food processor, as shown in Fig. 1 of the accompanying drawings, includes a machine base 10 for a juice container 20 and a -

food container 30 to be mounted thereon, and a vertical 15 motor 103 installed under the juice container 20. When the vertical motor 103 is started to activate the transmissi.or.

gears, the blade of the juice container 20 and the food container 30rotate and stir at the same time, consequently resulting in overload of the motor 103 and 20 wasting much electricity. In addition, when the juicer is used, a user has to engage the juice container on the machine base 10 and can then press a button to start the motor 103 to carry on stirring and blending whether the container cover 203 is properly closed or not.

25 Although it is easy to use such a previously-proposed juicer, owing to lack of safe protection an injury inflicted by the blade of the juicer can occur to a user if

his/her hand extends into the juice container 20 while it is in use, for example if the button is pressed by mistake, and is particularly dangerous for children.

Accordingly,. it is desirable to provide a food 5 processor which is able to economize electricity and is simple and safe in use.

A food processor embodying the present invention includes a hollow machine base having a juice container base formed on one side and a food container base on the 10 other.

The juice container base is preferably provided inside with a vertical motor having an upper rotating shaft to drive the juice container, and a lower rotating shaft transmitted to drive a food container by means of a belt, with the lower 15 rotating shaft affixed with a power chargeover device.

The power changeover device desirably consists of an actuating rod, a press member and a clutch. Preferably, when the juice container is mounted on the juice container base, the motor can directly drive the juice container to function.

20 But, desirably when the juice container is disengaged from the juice container base and the juice container base is covered with a cover, the stud of the cover will press down the actuating rod and the press member to push the clutch so as to let the vertical motor drive the food 25 container to operate by means of the belt.

Preferably, a vertical connecting rod is provided in one side of the juice container base far from the food container

base and restricted to shift up and down vertically only. The vertical connecting rod desirably has its top end facing a through hole on the top side of the juice container and 5 desirably has its bottom end form a push-pull block for pushing a lateral connecting rod which is confined to simply move back and forth horizontally.

The lateral connecting rod is preferably formed at the front end with a push-pull block to be fitted with a set of 10 vertical three sectional insert rods having a shape gradually shrinking from top to the bottom. Preferably, the first sectional insert rod has its top end face the lateral connecting rod and formed with a push-pull shaped chamber for receiving the push-pull block, the second 15 sectional insert rod is fitted around with a first spring and inserted in a sleeve, and the third sectional insert rod extends out of the bottom of the sleeve and is fitted around with a second spring having its bottom end push against a position-limiting member provided for the 20 third sectional insert rod to be inserted therein. Desirably, the sleeve around the second sectional insert rod has a lateral press rod extending out from one side, and a stop and a start micro-switch are respectively provided above and under the press rod for controlling the vertical 25 motor to stop and start rotating.

In addition, desirably the handle of the juice container is provided inside with a handle connecting rod shaped to

- match with the handle and having its bottom end inserted in the through hole in the juice container base for pressing the vertical connecting rod of the juice container base. The handle connecting rod preferably has its top 5 end bent into a flat plate having its bottom side pressing a spring and its topside provided with a press member, with the spring resiliently pushing against the handle connecting rod and keeping it in a hoisting condition.

Furthermore, the juice container is preferably provided with a 10 container cover having a protruding cover tongue formed at a rear end and corresponding to the handle, and a lateral rib facing the handle and having a press rod is formed under the cover tongue of the container cover.

Thus, when the juice container is engaged on the 15 juice container base, the bottom end of the handle connecting rod in the handle of the Juice container is exactly inserted in the through hole on the top side of the juice container and located above the vertical connecting rod.

20 The container cover is desirably closely mounted on the juice container in a way of turning around. When the container cover is turned around, preferably the bottom edge of the press rod under its cover tongue is shifted down to push against the press member of the handle connecting rod, forcing 25 the handle connecting rod to move down and compress the spring. At the same time, preferably the bottom end of the handle connecting rod is actuated to force the vertical

connecting rod to move down vertically to let the push-pull block of the vertical connecting rod push the lateral connecting rod horizontally to shift toward the insert rod. Thus, the front end of the lateral connecting 5 rod will make the insert rod to move downward together with the sleeve and compress the second spring, and at this time the press rod on one side of the sleeve is actuated to move down and compress the start micro-switch to turn on the vertical motor.

10 On the contrary, if the container cover is not tightly closed in position and the press rod of the container cover fails to touch the press member of the handle connecting rod, the spring will push the handle connecting rod to a hoisting condition, and the second IS spring in the juice container base will stretch again to push up the sleeve and the insert rod to let the press rod on one side of the sleeve touch the stop micro-switch to turn off the motor.

5 A preferred embodiment of a food processor embodying the present invention, as shown in Figs. 2 and 3, includes a hollow machine base 1, a juice container 2, a juice container base 11, a food container 3, and a food container base 12 as main components combined 10 together. The hollow machine base 1 is provided with a bulgy juice container base 11 on one side for engaging the juice container 2, and a food container base 12 on the other side for receiving the food container 3. Then, a lid 15 to be mounted on the juice container base 11 is provided with a stud 41 protruding downward at the bottom.

The juice container base 11 is installed inside with a vertical motor 13 having an upper and a lower rotating shafts 131 and 132 respectively provided on fop and at 20 the bottom. The upper rotating shaft 131 directly drives the juice container 2, while the lower rotating shaft 132 is transmitted to drive the food container 3 by means of a belt, with the lower rotating shaft 132 fixed with a power changeover device 5, as shown in Fig. 2.

25 The power changeover device 5 is positioned near one side of the food container base 12, and composed of an actuating rod 51, a press member 52 and a clutch 53.

The actuating rod 51 rests on the press member 52 pulled by a spring 54, with its top end extending out of the top surface of the juice container base. The press member 52 has its front end pressing the clutch 53, which is located 5 between an upper gear cover 55 and a lower transmission gear 56, with the upper gear cover 55 driven by the vertical motor 13 to rotate together with the lower transmission gear 56 at the same time. The clutch 53 is pressed down by the press member 52 and separated from 10 the upper gear cover 55, and the belt 133 for driving the food container is fitted around the lower transmission gear 56, as shown in Figs. 2 and 4.

In addition, as shown in Figs. 3, 5 and 6, a vertical connecting rod 14 is provided in one side of the juice 15 container base 11 far from the food container base 12 and restricted to move up and down vertically only. The vertical connecting rod 14 has its top end face the through hole 111 on top of the juice container base 11 and its bottom end form a push-pull block 141 resting 20 against a lateral connecting rod 15 which is confined to simply shift back and forth horizontally.

The lateral connecting rod 15 is formed with a push-pull block 151 at the front end to be connected with three vertical continual insert rods, 16, 162, 164 with a 25 shape gradually shrinking from top to the bottom. The first insert rod 16 has its top end formed with a push-pull shaped chamber 161 facing the lateral

connecting rod 15 and receiving its push-pull block 151.

The second insert rod 162 is fitted around with a first spring 163 and inserted in a sleeve 17, and the third insert rod 164 extends out of the bottom side of the 5 sleeve 17 and is fitted around with a second spring 165 having its bottom end pushing against a position-limiting member 166 provided for the third sectional insert rod 164 to be positioned therein, with the second spring 165 keeping the insert rods 16, 162, 10 164 in a pushing-up condition.

Further, the sleeve 17 fitted around the second insert rod 162 has a press rod 171 formed extending horizontally from one side, and a stop and a start micro-switches 18 and 19 are respectively provided 15 above and under the press rod 171 for controlling the vertical motor 13 to stop and to start rotating. The sleeve 17 together with the press rod 171 is forced by the second spring 165 to move up to force the press rod 171 compress the stop micro-switch 18.

20 In addition as shown in Figs. 7, 8 and 9, the handle 21 of the juice container 2 is provided inside with a handle connecting rod 22 having a shape matching with the handle 21 and having its bottom end inserted in the through hole 111 of the juice container base 11. The 25 handle connecting rod 22 has its top end bent into a flat plate 221 having its bottom side press a spring 222 fitted in the handle 21, as shown in Figs. 7 and 9, and its top

side provided with a protruding-up press member 223 having an arcuate top surface, as shown in Figs. 7 and 8.

The spring 222 pushes against the handle connecting rod 22 to keep it in a hoisting condition.

S Further, the juice container 2 is provided with a container cover 23 able to tightly cover up the juice container 2 only when it is turned around in position.

The container cover 23 is formed with a cover tongue 231 protruding out at a rear side and covering on the topside 10 of the handle 21. The cover tongue 231 has a lateral rib 232 formed at the bottom side to protrude downward, and the lateral rib 232 is provided with a press rod 233 protruding downward and facing the handle 21, with the bottom surface of the press rod 233 arc-shaped to IS conform to the actuate surface of the top end of the handle connecting rod 22, as shown in Fig. 8.

A food processor embodying the present invention can be used for food and juice processing respectively.

If the food processor is alternatively used for 20 processing food, the juice container 3 is first removed from the juice container base 11, and the lid 4 is covered on the juice container base 11, as shown in Fig. 10. When the lid 4 is covered on the juice container base 11, its stud 41 will be aligned to the actuating rod 51 and press 25 it down into the juice container base 11 to push the rear end of the press member 52 incline down, and at the same time the front end of the press member 52 will move up

to let the clutch 53 mesh with the upper gear cover 55.

Thus, when the vertical motor 13 begins to operate, its upper rotating shaft 131 will rotate idly, while the lower rotating shaft 132 will directly drive the upper gear S cover SS, the clutch 53 and the lower transmission gear 56 to rotate simultaneously, and the lower portion of the lower transmission gear 56 will be actuated to drive the transmitting belt 133 to rotate the food container 3 to carry on food processing. After finishing processing 10 food, the lid 4 on the juice container base 11 is removed to let the press member 52 recover its original position by the recovering force of the spring 54, as shown in Figs. 3 and 4.

By so designing, the food container 3 or the juice IS container 2 can be employed separately. However, when both the juice container 2 and the food container 3 are mounted on the machine base 1 at the same time, only the juice container 2 can be driven for processing. Under this condition, the food container 3 can't operate any 20 longer unless the juice container 2 is removed and the lid 4 is covered on the juice container base 1, thus lowering the load of the vertical motor 13 and economizing electricity.

On the contrary, in case the juice container is 25 alternatively used, firstly, the juice container 2 is directly engaged on the juice container base 11, as shown in Fig. 12, and the bottom end of the handle

connecting rod 22 in the handle 21 of the juice container 2 is exactly inserted in the through hole 111 on the top surface of the juice container base 11 and contacts with the top end of the vertical connecting rod 14 inside. At S this time, the first and the second springs 163 and 165 are respectively in a stretching condition, as shown in Fig. 6, therefore the press rod 171 on one side of the sleeve 17 will press the stop micro-switch 18 above it to keep the vertical motor 13 motionless not to rotate.

1Q Next, when the container cover 23 is deposited on the juice container 2 and turned around to close up the juice container 2 tightly at a positioning location, as shown in Fig. 13, its cover tongue 231 will synchronously be moved to be aligned to the handle 21 of IS the juice container 2. Meanwhile, the press rod 233 under the cover tongue 231 has its arcuate surface contacting with the arc-shaped surface on the top edge of the press member 223 and pushing against the press member 223 of the handle connecting rod 22, as shown in 20 Fig. 14. Thus, the vertical connecting rod 14 is pressed to move down by the press rod 223, and the spring 222 under the flat plate 221 becomes shrunken, as shown in Fig. IS. At the same time; the handle connecting rod 22 has its bottom end press the vertical rod 14 in the juice 25 container base 11 to move down to force the push-pull block 141 at the bottom end of the vertical rod 14 press and force the lateral connecting rod 15 to move forward

toward the first insert rod 16. In this case, the push-pull block 151 at the front end of the lateral connecting rod 15 is deeply inserted in the push-pull shaped chamber 161 on the top end of the first insert rod 16, as shown in 5 Fig. 15, to force the insert rod 16 together with the sleeve 17 outside the second insert rod 162 to shift down and make the second spring 165 shrunken, and synchronously the press rod 171 on one side of the sleeve 17 is also moved down to press the start 10 micro- switch 19 start the vertical motor 13 rotate to drive the juice container 2.

After finishing juice processing, the container cover 23 is reversely turned open to let its cover tongue 231 face the handle 21 no more, and make the bottom 15 edge of the press rod 233 fail to push against the press member 223 of the handle connecting rod 22, so that the spring 222 under the flat plate 221 recovers to move the handle connecting rod 22, as shown in Figs. 9 and 10. At the same time, the second spring 165 in the juice 20 container base 11 recovers to push up the first insert rod 16, the lateral connecting rod 15 and the vertical connecting rod 14 back to an original condition shown in Fig. 6. Thus, the stop micro-switch 18 will cut off the electricity of the vertical motor 13, stopping the 25 vertical motor 13.

With reference to the three insert rods 16, 162, 164 as described above,

the second insert rod 162 is fitted around with the first spring 163 and inserted in a sleeve 17. By so designing, if the container cover 23 is turned around to cover up the juice container 2 with an excessive force and make the 5 first insert rod 16 move down to a distance farther than that of the sleeve 17 moving down to the start micro-switch 19, this excessive distance can be absorbed by the first spring 163 shrunk in the sleeve 17. Thus, even if the first insert rod 16 is moved down too far, the 10 press rod 171 on one side of the sleeve 17 still can be kept in a condition of properly touching the start micro-switch 19, accordingly having a buffer effect.

Evidently, the container cover 23 plays a most important role in this invention because it controls the 15 juice container 2 to operate. In other words, whether or not the juice container 2 can function to carry on processing all depends on if the container cover 23 is turned to a positioning location and closed tightly. In case the container cover 23 is not closed tightly, the 20 juice container 2 cannot make electric connection for processing even through it has already been mounted on the juice container base 11. Besides, even if the container cover 23 is turned open by a curious child, the stop micro-switch 18 is pressed by the press rod 171 to 25 stop the vertical motor 13. Thus, even if a child extends a hand in the opened juice container 2, no injury is likely to occur, because the juice container 2 fails to make -

electric connection nor can it operate, thereby being not only easy in handling but safe in use as well.

While the preferred embodiment of the invention has been described above, it will- be recognized and 5 understood that various modifications may be made t h e r e i n.
