  However, when juices are made by cutting foods such as fruits and vegetables using this mixer, smooth juice may not be obtained due to insufficient mixer cutting properties. “Smooth juice” means that the proportion of fibrous particles having a size of 2.0 mm or more is small, and the proportion of fibrous particles having a size of more than 1.0 mm and less than 2.0 mm is large, It is a juice that feels good when touched.

  The subject of this invention is providing the mixer which can cut the fiber of cooking things, such as a fruit and vegetables favorably.

(1)
The mixer of the present invention includes a rotation drive mechanism, a blade portion, and a container. The blade portion is rotated by a rotation drive mechanism. The container surrounds the blade. The blade portion has a plurality of blades. The plurality of blades extend in different directions toward the container. The container has a plurality of ribs. The plurality of ribs are formed on the inner surface of the container. When one blade is at the shortest distance relative to the rib near the blade, the other at least one blade is at a position other than the shortest distance relative to the rib near the blade. .

  In a conventional mixer, when one vane is at the shortest distance to the rib near the vane, all other vanes are also at the shortest distance to the rib near the vane. is there. Therefore, the resistance to the rotating blade portion is increased, and the load on the rotation drive mechanism is increased. As a result, in the conventional mixer, power consumption increases, motor lock is likely to occur, and the durability of the rotary drive mechanism decreases. “Motor lock” is a phenomenon in which the rotational drive mechanism stops when a large load is temporarily applied to the rotational drive mechanism. Moreover, when the rotation speed of a blade part falls, since the fiber of cooking things, such as fruit and vegetables, becomes difficult to cut, it is difficult to obtain smooth juice. “Smooth juice” means that the proportion of fibrous particles having a size of 2.0 mm or more is small, and the proportion of fibrous particles having a size of more than 1.0 mm and less than 2.0 mm is large, It is a juice that feels good when touched.

  However, in the mixer of the present invention, when one blade is at the shortest distance with respect to the rib near the blade, at least one other blade is the shortest with respect to the rib near the blade. It is in a position other than the position of the distance. Therefore, the resistance to the rotating blade portion is smaller than that of the conventional mixer, and the load on the rotation drive mechanism is reduced. Thereby, in the mixer of the present invention, power consumption is reduced, motor lock is less likely to occur, and durability of the rotary drive mechanism is improved. Moreover, since it becomes difficult to reduce the rotation speed of a blade part, the fiber of a cooking thing becomes easy to be cut, and smooth juice is obtained.

The mixer of the present invention includes a rotation drive mechanism, a blade portion, and a container. The blade portion is rotated by a rotation drive mechanism. The container surrounds the blade. The blade portion has a plurality of blades. The plurality of blades extend in different directions toward the container. The container has a plurality of ribs. The plurality of ribs are formed on the inner surface of the container. When one blade faces a rib in the vicinity of the blade, at least one other blade does not face a rib in the vicinity of the blade.

  In a conventional mixer, when one blade faces a rib in the vicinity of the blade, all other blades also face a rib in the vicinity of the blade. Therefore, the resistance to the rotating blade portion is increased, and the load on the rotation drive mechanism is increased. As a result, in the conventional mixer, power consumption increases, motor lock is likely to occur, and the durability of the rotary drive mechanism decreases. Moreover, in the conventional mixer, since the rotation speed of a blade part falls and the fiber of a cooking thing becomes difficult to be cut, it is difficult to obtain smooth juice.

  However, in the mixer according to the present invention, when one blade faces a rib near the blade, at least one other blade does not face a rib near the blade. Therefore, the resistance to the rotating blade portion is reduced, and the load on the rotation drive mechanism is reduced. Thereby, in the mixer of the present invention, power consumption is reduced, motor lock is less likely to occur, and durability of the rotary drive mechanism is improved. Moreover, since it becomes difficult to reduce the rotation speed of a blade part, the fiber of a cooking thing becomes easy to be cut, and smooth juice is obtained.

In the mixer of (1) or (2) described above, the rib preferably has a first surface and a second surface. The first surface rises from the inner surface. The second surface is in contact with the first surface. In plan view, the inner surface is circular, and the first surface and the second surface are inclined in the direction of rotation of the blade portion as they go inward. Further, in plan view, the first angle formed by the normal line at the contact point between the inner surface and the first surface and the first surface is smaller than the second angle formed by the normal line and the second surface. .

  A 1st surface tends to disturb the flow of water because the water flow generated by rotation of a blade part hits. Due to the disturbance of the water flow, the cooked product is likely to flow along the second surface toward the center of the container, and easily comes into contact with the rotating blade portion. Therefore, the cooked product is easily cut by the blade portion, and a smooth juice is obtained.

  The mixer which concerns on this invention can cut | disconnect the fiber of cooking things, such as a fruit and vegetables favorably.

The ribs 410 to 450 may extend obliquely upward from below in a side view. The shapes of the ribs 410 to 450 may all be the same, some of them may be the same, or all may be different.

  When the upper blade 320 is at the position of the shortest distance with respect to the rib 410 in the vicinity thereof, the upper blade 330 is at a position other than the position of the shortest distance with respect to the rib 430 (or rib 440) in the vicinity ( (See FIG. 3). At the same time, the lower blade 340 is in a position other than the position of the shortest distance with respect to the rib 420 in the vicinity, and the lower blade 350 is in a position other than the position of the shortest distance with respect to the rib 450 in the vicinity. That is, when the upper blade 320 is at the position of the shortest distance with respect to the rib 410 in the vicinity thereof, the blades 330 to 350 are at positions other than the position of the shortest distance with respect to the ribs 420 to 450 in the vicinity thereof. It is in. Moreover, although the case of the upper blade | wing 320 in the position of the shortest distance with respect to the rib 410 in the vicinity was demonstrated, each of the blade | wings 330-350 in the position of the shortest distance with respect to the rib 420-450 in the vicinity was each demonstrated. The same applies to the case of.

  The case where the upper blade 320 and the rib 410 are the “shortest distance” is when the outermost portion of the blade 320 and the innermost portion of the rib 410 are the shortest distance in plan view. Say. In addition, when the upper blade | wing 320 is in the position of the shortest distance with respect to the rib 410 in the vicinity, a part of blade | wing 330-350 is the position of the shortest distance with respect to the rib 420-450 in each vicinity. There may be.

  Moreover, when the upper blade | wing 320 opposes the rib 410 in the vicinity, the upper blade | wing 330 does not oppose the rib 430 (or rib 440) in the vicinity. At the same time, the lower blade 340 does not face the adjacent rib 420, and the lower blade 350 does not face the adjacent rib 450. That is, when the upper blade 320 faces the rib 410 in the vicinity thereof, the blades 330 to 350 do not face the ribs 420 to 450 in the vicinity thereof. Moreover, although the case of the upper blade | wing 320 facing the rib 410 in the vicinity was demonstrated, it is the same also about each case of the blade | wing 330-350 facing the rib 420-450 in the vicinity. In addition, when the upper blade | wing 320 opposes the rib 410 in the vicinity, a part of blade | wings 330-350 may oppose the rib 420-450 in each vicinity.

  In the mixer 100, the number of ribs and the number of blades may be two or more, respectively. Further, in the plan view, when the ribs and the blades are arranged at equal intervals, at least one of the relationship between the shortest distance between the rib and the blade and the facing relationship between the rib and the blade is easily established. It is preferable that the number of blades is n and the number of ribs is (n + 1).

  Moreover, it is preferable that the blade part 310 has a blade | wing which does not oppose any of the ribs 410-450 in side view. In the mixer 100 having the blades, the fiber of the cooked product is easily cut, and a smooth juice is obtained.

  The shape of the rib 410 in plan view will be described with reference to FIG. Rib 410 has a substantially hexagonal shape in plan view, and includes first surface 411, second surface 412, third surface 413, fourth surface 414, and fifth surface 415. Have. The rib 410 may have a substantially polygonal shape having four or more sides in plan view.

  The first surface 411 and the fifth surface 415 rise from the inner surface 470. And the 1st surface 411 is easy to generate | occur | produce the water flow a3 which tends to disturb the flow of the water mentioned later. The second surface 412 is in contact with the first surface 411 and the third surface 413. The fourth surface 414 is in contact with the third surface 413 and the fifth surface 415.

  The first surface 411 and the second surface 412 are inclined in the rotation direction a <b> 1 of the blade portion 310 as it goes inward in plan view. Further, the first surface 411 and the second surface 412 are surfaces facing the rotation direction a1 of the blade portion 310.

  The 3rd surface 413, the 4th surface 414, and the 5th surface 415 are surfaces which do not oppose the rotation direction a1 of the blade part 310 in planar view. Note that the shapes of the third surface 413, the fourth surface 414, and the fifth surface 415 are not particularly limited, but are adjusted as appropriate in consideration of the strength of the rib 410 and the like.

  The first angle α is an angle formed between the normal line L at the contact point between the inner surface 470 and the first surface 411 and the first surface 411 in plan view. The second angle β is an angle formed between the normal L and the second surface 412 in plan view. The first angle α is smaller than the second angle β. Furthermore, the first angle α is preferably greater than 0 ° and less than or equal to 20 °, and the second angle β is preferably 70 ° or more and less than 90 °, and the first angle α and the second angle β The difference is preferably 50 ° or more and 70 ° or less. The rib 410 inclines in the rotation direction a1 of the blade portion 310 as it goes inward in plan view, and the surface facing the rotation direction a1 is between the second surface 412 and the third surface 413. You may have one or more.

  Next, the flow of the cooked food in the mixer 100 will be described with reference to FIG. First, by the rotation of the blade portion 310, the cooked product is cut into a fluid, and a water flow a2 flowing in the same direction as the rotation direction a1 of the blade portion 310 is generated. When the water flow a2 hits the first surface 411, the water flow a3 is disturbed. Due to the disturbance of the water flow a <b> 3, the cooked food, which is a fluid, is flowed by the water flow a <b> 4 flowing in the direction toward the center of the container 400 along the second surface 412, and easily comes into contact with the rotating blade portion 310. Therefore, in the mixer 100 of the present invention, the cooked product is easily cut by the blade portion 310, so that it is easy to become a smooth juice. “Smooth juice” means that the proportion of fibrous particles having a size of 2.0 mm or more is small, and the proportion of fibrous particles having a size of more than 1.0 mm and less than 2.0 mm is large, It is a juice that feels good when touched.

  On the other hand, the shape of the rib 510 of the container 500 in a plan view according to the conventional mixer and the flow of the cooked food in the conventional mixer will be described with reference to FIG. The rib 510 has a substantially triangular shape in plan view, and has surfaces 511 and 512 rising from the inner surface 570. The surface 511 is in contact with the surface 512. The cooked food is cut by the rotation of the blade portion 310 to become a fluid, and a water flow a2 flowing in the same direction as the rotation direction a1 of the blade portion 310 is generated. The cooked product that is caused to flow by the water flow a2 is caused to flow by the water flow a5 that generally flows in the direction along the surface 511. The water flow a5 has a lower momentum flowing in the direction toward the center of the container 500 than the water flow a4. Therefore, the food to be cut by the conventional mixer is less likely to flow in the direction toward the center of the container 500 than the food to be cut by the mixer 100 of the present invention, so that it comes into contact with the rotating blade portion 310. Hateful.

  The Example which concerns on the mixer 100 of this invention, and a comparative example are demonstrated. In addition, this invention is not limited at all by these Examples.

Example 1
100 g of carrots cut into 4 equal parts after being cut into 2 cm round pieces as a cooked product and 180 ml of water were put into the mixer 100, and the blade 310 was rotated at 100 V for 1 minute to obtain juice. At this time, the power consumption of the mixer 100 was 121W. The obtained juice was passed through a sieve having an opening of 2.0 mm and a sieve having an opening of 1.0 mm. And about the fiber in the juice which remained on the sieve whose mesh opening is 2.0 mm, the fiber in the juice which remained on the sieve whose mesh opening is 1.0 mm, and the fiber in the juice which passed through the above two sieves, Each weight was measured.

  Next, the weight of the fiber in the juice remaining in each sieve and the weight of the fiber in the juice that has passed through the two sieves are divided by the total weight of the fibers in the juice, respectively. The particle size distribution of the fiber was calculated. As a result, the proportion of fibrous particles having a size of 2.0 mm or more is 6%, the proportion of fibrous particles having a size of more than 1.0 mm and less than 2.0 mm is 43%, 1.0 mm or less. The proportion of fibrous particles having a size was 51%. FIG. 6 is a graph of the above values.

(Comparative Example 1)
A juice was obtained in the same manner as in Example 1 except that a conventional mixer was used. In particular, the condition of the shortest distance between the blade and the rib according to the conventional mixer is the same as the condition of the shortest distance between the blade and the rib according to the mixer of Example 1. In the conventional mixer, when one blade faces a rib near the blade, all other blades face the rib near the blade. In the conventional mixer, when one blade is at the shortest distance from the rib near the blade, all the other blades are at the shortest distance from the rib near the blade. It was in. And the shape of the rib was a substantially triangle in planar view.

  In the same manner as in Example 1, the particle size distribution of the fibers in the juice was calculated. As a result, the proportion of fibrous particles having a size of 2.0 mm or more is 51%, the proportion of fibrous particles having a size of more than 1.0 mm and less than 2.0 mm is 12%, 1.0 mm or less. The proportion of fibrous particles having a size was 37%. FIG. 7 is a graph of the above values.

  The juice of Example 1 was smaller than the juice of Comparative Example 1 with respect to the proportion of fibrous grains having a size of 2.0 mm or more. Moreover, the juice of Example 1 was larger than the juice of the comparative example 1 about the ratio of the fiber grain which is a magnitude | size exceeding 2.0 mm and less than 2.0 mm. When the sensory test was conducted by actually drinking the juice according to Example 1 and the juice according to Comparative Example 1, the juice according to Example 1 was a smoother juice than the juice according to Comparative Example 1. .

(Example 2)
Except for the following, juice was obtained in the same manner as in Example 1. First, a voltage was applied at 50 V, the voltage was increased to 95 V at a rate of 1 V for 3 seconds, and then the voltage was maintained at 95 V. The power consumption of the mixer 100 when the voltage was maintained at 95 V was 110 W. When the number of occurrences of motor lock until juice was completed was counted, the number of occurrences of motor lock was 8. “Motor lock” is a phenomenon in which the rotational drive mechanism 210 stops due to a temporary heavy load on the rotational drive mechanism 210.

  In the same manner as in Example 1, the particle size distribution of the fibers in the juice was calculated. As a result, the proportion of fibrous particles having a size of 2.0 mm or more is 11%, the proportion of fibrous particles having a size of more than 1.0 mm and less than 2.0 mm is 34%, 1.0 mm or less. The ratio of the size of the fibrous grain was 55%. FIG. 8 is a graph of the above values.

(Example 3)
Except for the following, juice was obtained in the same manner as in Example 1. First, a voltage was applied at 50 V, the voltage was increased to 100 V at a rate of 1 V for 3 seconds, and then the voltage was maintained at 100 V. The power consumption of the mixer 100 when maintaining the voltage at 100 V was 120 W. When the number of occurrences of motor lock until juice was completed was counted, the number of occurrences of motor lock was three.

  In the same manner as in Example 1, the particle size distribution of the fibers in the juice was calculated. As a result, the proportion of fibrous particles having a size of 2.0 mm or more is 7%, the proportion of fibrous particles having a size of more than 1.0 mm and less than 2.0 mm is 41%, 1.0 mm or less. The proportion of fibrous particles having a size was 52%. FIG. 9 is a graph of the above values.

(Comparative Example 2)
A juice was obtained in the same manner as in Comparative Example 1 except for the following. First, a voltage was applied at 50 V, the voltage was increased to 100 V at a rate of 1 V for 3 seconds, and then the voltage was maintained at 100 V. The power consumption of the mixer 100 when maintaining the voltage at 100 V was 130 W. In addition, even if the voltage was applied at 95V, the blade part 310 did not rotate. When the number of occurrences of motor lock until juice was completed was counted, the number of occurrences of motor lock was 71 times. In addition, smoke was generated from the rotary drive mechanism 210 three times by the motor lock. After the generation of smoke due to the motor lock, the rotation drive mechanism 210 was cooled to lower the temperature, and then the voltage of 100 V was applied to resume the rotation of the blade portion 310.

  In Example 2, the blade part 310 was rotated at 95 V, which is a voltage lower than 100 V of Example 3. However, the fiber particle size distribution in the juice according to Example 2 was not significantly different from the fiber particle size distribution in the juice according to Example 3. For this reason, the mixer 100 of the present invention was able to obtain a smooth juice without a significant decrease in performance even when the voltage was lower than 100V.

  In Example 2, the blade 310 was rotated at a voltage of 95 V, but in Comparative Example 2, the blade 310 was not rotated at a voltage of 95 V. Therefore, the mixer 100 of the present invention was able to rotate the blade 310 even when the voltage was lower than 100V.

  The number of occurrences of motor lock was 8 times in Example 2, 3 times in Example 3, and 71 times in Comparative Example 2. Therefore, the mixer 100 of the present invention was able to suppress the occurrence of motor lock as compared with the conventional mixer.

  The power consumption during the rotation of the blade 310 was 110 W in Example 2, 121 W in Example 3, and 130 W in Comparative Example 2. Therefore, in the mixer 100 of this invention, the power consumption at the time of rotation of the blade part 310 was reduced from the conventional mixer.

<Effect in this embodiment>
In a conventional mixer, when one vane is at the shortest distance to the rib near the vane, all other vanes are also at the shortest distance to the rib near the vane. is there. Therefore, the resistance to the rotating blade portion is increased, and the load on the rotation drive mechanism is increased. As a result, in the conventional mixer, power consumption increases, motor lock is likely to occur, and the durability of the rotary drive mechanism decreases. Moreover, since the rotation speed of a blade part falls and the fiber of a cooking thing becomes difficult to be cut, it is difficult to obtain smooth juice.

  However, in the mixer 100 of the present invention, when the upper blade 320 is at the shortest distance from the rib 410 in the vicinity thereof, the blades 330 to 350 are shortest to the ribs 420 to 450 in the vicinity thereof. It is in a position other than the position of the distance. Therefore, the resistance to the rotating blade 310 is reduced, and the load on the rotation drive mechanism 210 is reduced. As a result, in the mixer 100 of the present invention, power consumption is reduced, motor lock is less likely to occur, and the durability of the rotary drive mechanism 210 is improved. Moreover, since it becomes difficult to reduce the rotation speed of the blade part 310, the fiber of a cooking thing becomes easy to be cut, and smooth juice is obtained.

  In a conventional mixer, when one blade faces a rib in the vicinity of the blade, all other blades also face a rib in the vicinity of the blade. Therefore, the resistance to the rotating blade portion is increased, and the load on the rotation drive mechanism is increased. As a result, in the conventional mixer, power consumption increases, motor lock is likely to occur, and the durability of the rotary drive mechanism decreases. Moreover, in the conventional mixer, since the rotation speed of a blade part falls and the fiber of a cooking thing becomes difficult to cut, it is difficult to obtain smooth juice.

  However, in the mixer 100 of the present invention, when the upper blade 320 faces the rib 410 in the vicinity thereof, the blades 330 to 350 do not face the ribs 420 to 450 in the vicinity thereof. Therefore, the resistance to the rotating blade 310 is reduced, and the load on the rotation drive mechanism 210 is reduced. As a result, in the mixer 100 of the present invention, power consumption is reduced, motor lock is less likely to occur, and the durability of the rotary drive mechanism 210 is improved. Moreover, since it becomes difficult to reduce the rotation speed of the blade part 310, the fiber of a cooking thing becomes easy to be cut, and smooth juice is obtained.

  The first surface 411 is disturbed by the water flow a <b> 2 generated by the rotation of the blade portion 310, thereby disturbing the water flow a <b> 3. Due to the disturbance of the water flow a <b> 3, the cooked food is likely to flow along the second surface 412 toward the center of the container 400, and easily comes into contact with the rotating blade portion 310. Therefore, the cooked product is easily cut by the blade 310, and a smooth juice is obtained.

The connecting portion 416 is a curved surface having a concave surface when the water flow a <b> 2 strikes in plan view. Further, the rib 410a has a connecting portion 417 formed between the inner surface 470 and the fifth surface 415 in plan view. The ribs 420a, 430a, 440a, and 450a have connecting portions 416 and 417 similarly to the rib 410a.

  As illustrated in FIG. 11, the water flow a <b> 2 smoothly hits the first surface 411 by the connecting portion 416, so that the rib 410 a can easily generate the water flow a <b> 3. Therefore, this water flow a3 causes the cooked product to flow along the second surface 412 in the direction a4 toward the center of the container 400a, and more easily come into contact with the rotating blade portion 310. Therefore, the cooked product is more easily cut by the blade 310, and a smooth juice is obtained.

(B)
As shown in FIG. 12, the container 400b of the mixer 100b may have upper ribs 410b and 440b and lower ribs 420b and 430b. The upper ribs 410b and 440b are formed at upper positions that face the upper blades 320 and 330 and do not face the lower blades 340 and 350 when the blade portion 310 is rotated in a side view. The lower ribs 420b and 430b are formed at lower positions that face the lower blades 340 and 350 and do not face the upper blades 320 and 330 when the blade portion 310 is rotated in a side view.

  In the mixer 100b, when the upper blade 320 faces the upper rib 440b in the vicinity thereof in the side view, the upper blade 330 does not face the lower rib 420b in the vicinity. At the same time, the lower blade 350 faces the nearby rib 430b, but the lower blade 340 does not face the nearby upper rib 410b. Therefore, the resistance to the rotating blade 310 is reduced, and the load on the rotation drive mechanism 210 is reduced. Thereby, in the mixer 100b of the present invention, power consumption is reduced, motor lock is less likely to occur, and the durability of the rotary drive mechanism 210 is improved. Moreover, since it becomes difficult to reduce the rotation speed of the blade part 310, the fiber of a cooking thing becomes easy to be cut, and smooth juice is obtained.

  The arrangement of the blades 320 to 350 and the ribs 410b to 440b is such that when one blade faces a rib in the vicinity of the blade in a side view, at least one other blade is in the vicinity of the blade. If it does not face the rib, it may be changed as appropriate.
