Detailed Description

Example (b):

As shown in fig. 1, 2, 3, 4 and 5, the self-cleaning food processor of the present invention is schematically constructed. Including the cup 01 that is used for carrying out food preparation machine, the bottom of cup is equipped with motor 02, the motor shaft of motor 02 passes the bottom of cup 01 and with set up in the crushing blade 04 of cup 01 inside is connected, be equipped with bowl cover 03 on the cup 01, bowl cover 03 bottom is formed with the supplementary chamber of upwards sunken, supplementary chamber with the cup surrounds formation food processing region and is used for comminuted processing. When the food processor works, the materials in the cup body 01 upwells into the auxiliary cavity along the cavity wall of the cup body. The food processor is further provided with a water tank 05, wherein the water tank 05 supplies water into the cup body 01 for crushing the materials to form slurry, and additionally, water can be supplied for cleaning the food processor area.

The side wall of the cup body 01 is provided with turbulence ribs 011, the distance from the bottom of the turbulence ribs 011 to the bottom of the cup body is h3, the distance from the highest position of the crushing blade 04 to the bottom of the cup body is h1, and h1 is not less than h 3. The crushing blade is positioned at the flow disturbing position of the flow disturbing rib. At food preparation machine abluent in-process, when the crushing blade rotates at a high speed, can drive the high-speed centrifugal rotation of the cleaning fluid in the cup, cleaning fluid can be better, thereby the directness moves along the lateral wall of cup and touches the vortex muscle of cup lateral wall, at this moment, cleaning fluid's liquid flow direction and velocity of flow all can change, some liquid flow can block the inclined plane direction motion along the vortex muscle, the cleaning fluid can be realized climbing to the rim of a cup department of cup along the inclined plane of vortex muscle, and form the liquid level district of V-arrangement, when the wall of a cup of the sweeping cup of cleaning fluid, can be to the incomplete stain of thick liquid on the wall of a cup, the residue erodees.

Because cup vortex muscle can be more direct contact with the liquid stream, so, have more washing liquid to climb to the rim of a cup department of cup to can erode to the bowl cover, wash the bowl cover, simultaneously, along with smashing blade rotation speed gradually weakening, washing liquid is under the effect of gravity, again along the wall of a cup downward reflux of cup, forms to the wall of a cup

The crushing blade is installed at the end part of the motor shaft, the distance from the end part of the motor shaft to the bottom of the cup body is H, the distance from the cup cover to the bottom of the cup body is H, and H is less than or equal to 15H.

The cup cover is cleaned by rotating and stirring water through the crushing cutter, the initiating point of water flow motion is in a region near a position H, the highest point of the water flow motion is in the position H, when H is larger than 15H, the speed of the liquid flow reaching the cup cover can be obviously weakened due to overhigh crushing cup body, the process resistance is increased, and at the moment, the washing effect of the water flow on the cup cover is poor. If the position of vortex muscle is higher than crushing blade, the liquid stream of vortex muscle lower part will be circular motion, and the liquid stream is relatively poor to motor shaft and crushing cutter washing effect.

In this embodiment, the angle γ between the side wall of the cup and the bottom of the cup is greater than 90 °. The included angle beta between the longitudinal section line of the turbulence rib and the bottom of the cup body is larger than 90 degrees.

because the food preparation machine of this embodiment has surrounded by cup and bowl cover and has formed the food processing region, and cup and bowl cover cooperation department are in sealing connection basically, consequently, food preparation machine can drive the liquid in the cup through smashing the blade, washs the food processing region by oneself, and need not manual intervention, operates safety and convenient more.

Specific as shown in fig. 2, the arrow indicates that the cleaning solution can climb to the rim of a cup department of cup along the inclined plane of vortex muscle to form the liquid level district of V-arrangement, when the wall of a cup of the swept cup of cleaning solution, can erode the residual of the thick liquid on the wall of a cup, and because the hindrance of cup bottom, so, have more cleaning solution to climb to the rim of a cup department of cup, thereby can erode to the bowl cover, wash the bowl cover. Simultaneously, along with smashing the gradual weakening of blade rotation speed, washing liquid can flow back downwards along the cup wall of cup under the effect of gravity, forms and carries out the washing of second time to the cup wall to, through smashing the rotation repeatedly of blade and stopping, realize that washing liquid washs the circulation of whole crushing region.

In addition, a part of liquid can rush to the middle area, and the flow velocity of the part of cleaning liquid is faster because the turbulence ribs on the side part of the cup body extend to the bottom of the cup body. And when the crushing blade rotates at a high speed, the middle area of the crushing cutter is in a vacuum state, at this time, the motor shaft and part of the crushing blade in the vacuum area cannot be washed by water flow, the bean dregs are more easily bonded due to high temperature in the pulping area, and at this time, the motor shaft and the crushing cutter in the vacuum area can be effectively cleaned. If the turbulent flow ribs are higher than the crushing blades, liquid flow at the lower parts of the turbulent flow ribs can move circularly, and the washing effect of the liquid flow on the motor shaft and the crushing cutters is poor.

in this embodiment, the lateral wall of the cup and the bottom of the cup form an angle of more than 90 °, that is, the lateral wall of the cup is inclined, and the inclination makes the liquid flow climb more easily in the view of the flow direction of the cleaning liquid, the resolution of the force is larger, and the total height of the cup is reduced in the degree of meeting the corresponding capacity, and at this time, the height to be climbed corresponding to the cleaning liquid can be reduced, which also corresponds to the reduction of the work required to be done by the cleaning liquid. Under the same condition, the climbing height of the cleaning liquid is increased, and the impact force of the cleaning liquid on the cup cover is also increased, so that the cleaning effect is further improved.

For the turbulence ribs, the included angle between the longitudinal section line of each turbulence rib and the bottom of the cup body is larger than 90 degrees, so that the turbulence ribs are more beneficial to the continuous climbing of liquid flow, the cleaning liquid in the central area is prevented from being reflected, and in order to better clean areas such as the cup cover, the motor shaft and the like, the included angle between the longitudinal section line of each turbulence rib and the bottom of the cup body is larger than 95 degrees and smaller than 110 degrees.

in this embodiment, the spoiler rib includes a spoiler surface and a back flow surface, and a vertical surface is formed between the joint of the spoiler surface and the back flow surface and the center of the cup body, and an included angle between the spoiler surface and the vertical surface is α, where α is greater than 110 ° and less than 160 °. As shown in fig. 3, the moving direction of the washing liquid is shown by the arrows, and the washing effect of the motor shaft and the crushing cutter is optimal after the direction of the liquid flow is changed.

At food preparation machine, the cleaning process, when smashing the high-speed rotation of blade, the washing liquid in the cup body can be driven rotatoryly, and its liquid stream can produce centrifugal force under high-speed circular motion's the condition, and centrifugal force effect is used in the cup inner wall, and when the liquid stream reached certain rotational speed, under the effect of centrifugal force, the liquid stream can be followed cup inner wall and upwards "crawled", then also can "crawl" to the bowl cover, finally returns to the cup bottom along the bowl cover shape. The larger the force of liquid flow towards the cup cover is, the more beneficial the cleaning of the cup cover is, the factors determining the size of the liquid flow impulse force towards the cup cover comprise the initial flow rate of the liquid flow and the process resistance, and the process resistance is adjusted by arranging the turbulence ribs and the positions and the inclination of the turbulence ribs.

For the limitation of the initial flow rate, the initial speed is determined by the crushing blade and the rotation speed of the motor, theoretically, the higher the rotation speed of the motor is, the stronger the water stirring of the crushing blade is, and when the rotation speed of the motor is too high, most of the water is thrown to the upper area, the water around the crushing cutter will be little and little, the problem of unstable cleaning water circulation will occur, and the noise will occur to the machine, so the cleaning efficiency and the stable water circulation are considered, in the embodiment, when the motor drives the crushing blade to clean the cup body, the rotation speed of the motor is not more than 20000 rpm and not less than 6000 rpm. If the rotating speed of the motor is too low, good centrifugal liquid flow cannot be formed, and the cup cover cannot be cleaned better.

In the utility model discloses in, smash the blade and include at least three sword leaf, be equipped with the blade on the sword leaf, wherein have the blade orientation of a sword leaf at least the direction of bowl cover, smash the blade and have a sword leaf of bending at least. In the specific embodiment, taking 4 blades as an example, as shown in fig. 4, reference numerals 041, 042, 043 and 044 are four blades of the crushing blade 04, and 0411, 0421, 0431 and 0441 are cutting edges corresponding to the four blades, respectively, and the cutting edges are all upward, and when the food processor is installed in the food processor, the cutting edges face the direction of the cup cover. And the knife blades 041 and 044 are bent knife blades.

When the motor drives the crushing blade to rotate towards the cutting direction, the crushing blade drives the liquid flow to move not only in a circular manner, but also in a vertical upward manner due to the cutting edge of the blade, and when the crushing blade rotates anticlockwise, the crushing blade is similar to an impeller which pumps water upwards, so that the initial speed of the liquid flow can be accelerated under the dual actions of the centrifugal force of the circular movement and the vertical upward pumping force, and the cup cover is more favorable for flushing.

Certainly, the upward draft of realization liquid flow is not restricted to four blade blades all upwards, and at least one also can realize the effect, and the effect is just not obvious, if four blade blades all down, water top-down motion around the crushing blade, promptly water dashes earlier to crushing cup bottom again along the upstream motion of lateral wall, and such a motion mode is under the condition that the vortex muscle extends to crushing cup bottom, and the motion hindrance to rivers is great, and the liquid stream can't wash the bowl cover totally basically like this, or the scouring force is very weak. If all the characteristic requirements are met, the liquid flow is in the best state when the cup cover is washed, and the liquid flow can form a powerful circumferential rotation effect on the cup cover under the dual actions of circumferential motion and vertical motion.

in the embodiment, the distance from the highest position of the crushing blade to the bottom of the cup body is h1, the liquid level height in the cup body is a when the cup body is cleaned, and a is more than or equal to h1 and less than or equal to 3h 1.

When the crushing blade rotates, a part of liquid flow moves upwards, water around the crushing blade is reduced, at the moment, the blade cannot fully achieve the effect of stirring water, so the water level height of water for washing at one time is larger than h1, if the water amount is increased, water resources are wasted, the actual load of the crushing blade is increased due to the fact that water is increased, better liquid flow is not favorably formed, and therefore a is more than or equal to h1 and less than or equal to 3h 1.

In the embodiment, the height of the turbulence ribs is S, and the height of the cup body is L, wherein the ratio of S to L is less than or equal to 9 to 10. If the vortex muscle is too high, at the in-process of food processing, can influence kibbling effect, and make more materials strike the bowl cover, be unfavorable for when smashing the effect, also increased the degree that the sediment was remained to the bowl cover. In this embodiment, the radial depth of the turbulence rib is c, the radius of the cup body is d, and c is not less than 0.06: d is less than or equal to 0.3. Thus, the turbulent flow effect of the ribs in the radial direction is ensured, and the ribs are ensured to be crushed and cleaned at the same time.

In this embodiment, the diameter of the cup mouth of the cup body is m, the diameter of the cup cover matched with the cup body is n, and m is not less than 0.8: n is less than or equal to 1.2, and the cup body and the cup cover are basically in a coating and sealing state in the process of enclosing, so that the problem that the cleaning is not in place due to overlarge gap between the cup body and the cup cover is solved.

In addition, in the embodiment, the distance from the top of the turbulence rib to the top of the cup cover is b, b is more than or equal to 10mm, in the cleaning process of the food processor, when the crushing blade rotates at a high speed, the cleaning liquid in the cup body can be driven to rotate centrifugally at a high speed, the cleaning liquid can move along the side wall of the cup body so as to touch the turbulence rib on the side wall of the cup body, at the moment, the liquid flow direction and the flow speed of the cleaning liquid can change, part of the liquid flow can move along the direction of the turbulence rib blocking inclined plane, the cleaning liquid can climb to the cup mouth of the cup body along the inclined plane of the turbulence rib and form a V-shaped liquid level area, when the cleaning liquid sweeps across the cup wall of the cup body, the cleaning liquid can scour residual liquid stains and residues on the cup wall, and because the distance is arranged between the cup cover and the turbulence rib, the cleaning liquid can climb to the cup mouth, thereby forming a scouring effect by inclining upwards and further better cleaning the cup cover.

That is to say, when smashing the high-speed rotation of blade, the water in the cup can be driven rotatoryly, the liquid stream can lead to the liquid stream diversion because of blockking of vortex muscle when the regional internal rotation of vortex muscle height, the circular motion of liquid stream under centrifugal force effect originally has been destroyed to the existence of vortex muscle, form irregular liquid stream motion, and the liquid stream is when vortex muscle top, because of the circumferencial direction is regular non-blocking structure, the event liquid stream can be stable circular motion, however the circular motion of this kind of liquid stream is comparatively favourable to the washing of bowl cover, can the omnidirectional a lot of wash the residue on the bowl cover top, if the abluent liquid stream is like the regional irregular motion of vortex muscle, appear easily on the bowl cover and wash the dead angle, and the number of times of scouring can't guarantee. However, the liquid flow is not stable circular motion in all areas above the turbulence ribs, when the liquid flow moves in the height area of the turbulence ribs and is switched to the motion above the turbulence ribs, a section of transition area exists in the axial direction, the transition area is the conversion of the liquid flow irregularly moving to regular motion, so that the distance b from the top of the cup cover to the top of the turbulence ribs is larger than the height of the transition area, the stable regular circular motion of the liquid flow at the top of the cup cover can be ensured, the height of the transition area is about 10mm, and therefore b is larger than 10 mm. Similarly, in this embodiment, h3 is greater than 10mm, that is, when the distance from the bottom of the spoiler to the bottom of the cup body is set, it must be greater than 10mm, otherwise, the circular motion of the bottom is affected, and the overall cleaning effect is affected.

In addition, in the embodiment, the food processor needs to be cleaned at least twice, and the liquid level in the cup body is not less than h3 each time the food processor is cleaned.

The food processor of the utility model is a food processor which can make liquid drinks such as soybean milk. It will be appreciated by those skilled in the art that the present invention includes, but is not limited to, those illustrated in the drawings and described in the detailed description above.
