Description

Food processor with good noise reduction effect

Technical Field

The utility model relates to the technical field of food processing devices, in particular to a food processing machine with good noise reduction effect.

Background

With the development of food processing machines, people gradually begin to pursue higher quality use experience, traditional food processing machines are based on product pricing restriction and simple drive demand, often all adopt series excitation motor to drive, but series excitation motor is because motor transmission efficiency undulant great, axial-flow radiating efficiency low, the frame is bulky, the obvious multiple problem of noise etc. of noise, market feedback is full of the problem, has a lot of structural optimization in the prior art, for example: various different types of technical innovations such as sound-proof housing, shock pad, fall cotton, heat dissipation wind channel, but limited by motor self attribute, all fail to have more obvious effect of making an uproar, heat dissipation or miniaturization, have the product that can solve above-mentioned problem simultaneously to appear more.

In order to solve the problems that the series excited motor is still large in noise and large in occupied space when being applied to a food processor, researchers adopt brushless motors to replace the series excited motor later. Although brushless motors have advantages such as small size, low noise, forward and reverse rotation, compared with series motors, the demand for light noise is increasing for consumers, and the demand for light noise cannot be satisfied by replacing the brushless motors alone. Therefore, some researchers consider the noise reduction scheme from other directions to improve the user experience.

For example, patent application number 201710720155.6 discloses heat dissipation host computer and broken wall machine of making an uproar fall in electrical apparatus, is suitable for defining the wind guide duct with the motor cover through setting up wind channel side cap subassembly, and left wind channel apron and left wind channel groove define left wind guide duct, and right wind channel apron and right wind channel groove define right wind guide duct, and the wind guide duct is the stereoplasm wind channel, sets up the noise that noise reduction cotton reduction motor produced at the high-speed vibration in-process in this wind guide duct. And an upper motor cover and an upper motor sealing ring are arranged above the left air channel and the right air channel, an air channel bottom cover component is arranged below the motor, and the air channel bottom cover component comprises an air channel upper cover and an air channel lower cover which are assembled in an adaptive manner, and an air channel sealing ring positioned between the air channel upper cover and the air channel lower cover. Therefore, although the scheme plays a certain role in noise reduction, on one hand, the whole air duct has more accessories and complex installation, and the assembly and the sealing between the left air duct groove, the right air duct groove, the left air duct cover plate, the right air duct cover plate, the upper motor cover and the air duct bottom cover assembly are needed to be considered; on the other hand, because the wind channel is around the periphery at the motor, its wind channel space is very little, needs to install the amortization cotton in this space, and the assembly step and the assembly degree of difficulty must be increased, and because the wind channel has tortuous route, amortization cotton can't laminate on the wind channel inside wall well, also can't shelter from all wind channel inside walls, and the effect of making an uproar falls is not fine.

For example, patent No. 201420352840.X discloses a dust collector with a motor suspension fixing structure, wherein a flexible air duct is arranged between an air outlet of a dust box and an air suction opening of a motor so as to separate the dust box from the motor, and the dust box is prevented from being directly driven to vibrate through a hard air duct when the motor vibrates, so that a phenomenon of tingling hands exists when hands touch the outer surface of the dust collector. However, this solution does not take into account how the flexible duct is arranged so that wind speed noise generated when wind generated by the motor passes through the flexible duct is effectively reduced.

For example, patent application number 201520258649.3 discloses a telescopic fan housing mechanism and install this telescopic fan housing mechanism's container, and on the fan housing's of container was installed again the fan housing mount, can hide the fan housing shrink to the machine inside during transportation, and project scene pulls out the fan housing from the machine inside to convenient transportation and use. In this solution, the noise reduction of the container by how the flexible hood is arranged is not considered.

To sum up, the above-mentioned prior art does not all consider the noise influence that brings with the wind that reduces the motor and produce through how to set up flexible wind channel, especially does not consider how to set up motor and flexible wind channel in the food processor field in order further to reduce operating noise, promotes user's use and experiences the sense.

In this embodiment, the pulverizing blade 131 is driven by the brushless motor 11, and the pulverizing blade 131 rotates in the cup 13 to pulverize the food material. In this embodiment, the brushless motor 11 is used instead of the conventional series motor, and the volume is smaller and the noise is lower than that of the series motor case 1. Of course, the food processor is often required to make some delicacies to be heated, such as soybean milk, fish soup, etc., and for this purpose, the heating plate 12 may be disposed at the bottom of the cup 13 to meet the heating requirement of the food. In a preferred embodiment, referring to fig. 2, for integration, the mounting structure of the brushless motor 11 is simplified, and the heat-generating plate 12 and the upper end cover 111 may be integrally formed as one piece, or integrally injection-molded as one piece. In the present utility model, whether or not the food processor includes the heat generating plate 12 and the manner of fixing the heat generating plate 12 to the upper cover 111 are not particularly limited.

Specifically, under one embodiment of the present application, the end cover is provided with a first air outlet 1121 and an air inlet 1111 staggered with the first air outlet, the bottom of the casing 1 is provided with a second air outlet 3, a soft exhaust pipe 4 is connected between the first air outlet 1121 and the second air outlet 3, an inner seat 2 of the stand is provided below the brushless motor 11, the lower end of the inner seat 2 of the stand extends downwards to be connected with the bottom surface of the casing 1, and the exhaust pipe 4 is partially arranged in the inner seat 2 of the stand.

In this scheme, at first through adopting brushless motor 11 to replace current series excited machine for food processor compares series excited machine small, noise is low. On the basis, the exhaust pipe 4 is made of soft materials, so that the exhaust pipe 4 is bent and deformed, the propagation path of wind is prolonged, the propagation direction of the wind is changed, the energy of the wind is weakened, and the effect of reducing noise is achieved. The frame inner seat 2 that this scheme still sets up to be connected with the bottom surface of casing 1 goes partly parcel exhaust pipe 4 at least with the frame inner seat to with exhaust pipe 4 part holding in this frame inner seat 2, and make the noise part separation of the exhaust pipe of holding in frame inner seat 2 keep off in frame inner seat 2, and then reduce the sound of following 3 exhaust wind of second air outlet, promote user's use experience and feel.

It should be noted that the lower end of the inner seat 2 extends downward to connect with the bottom surface of the casing 1, including that the inner seat 2 is directly connected with the bottom surface of the casing 1, or that the inner seat 1 is connected with the bottom surface of the casing 1 through other components such as a sealing member 5. In addition, the staggered arrangement of the first air outlet 1121 and the air inlet 1111 includes that the first air outlet 1121 and the air inlet 1111 are both positioned on the side wall of the end cover, but are opposite to each other; alternatively, the air inlet 1111 is disposed at the top of the end cover, and the first air outlet 1121 is disposed on a side wall of the end cover, which is not particularly limited.

In a preferred embodiment, referring to fig. 1, in order to ensure the sealing effect between the bottom surface of the housing and the bottom surface of the housing, a sealing member 5 is disposed between the bottom wall of the housing inner base 2 and the bottom surface of the housing 1, so that the housing inner base 2 is in sealing connection with the bottom surface of the housing 1.

In one embodiment of the present application, in order to raise the noise blocking effect of the exhaust duct 4 by the inner seat 2 of the machine base as much as possible, the exhaust duct 4 is provided in the inner seat 2 of the machine base by more than half of its length. Thus, at least half and more exhaust pipes 4 are arranged in the inner seat 2 of the engine base, and the inner cavity of the inner seat 2 of the engine base forms a first noise barrier for the exhaust pipes 4 positioned in the inner seat, thereby improving the noise reduction effect. Specifically, the present application provides the following examples:

Example 1: the second air outlet 3 is positioned on the bottom surface of the casing, and the plumb projection of the second air outlet 3 falls into the projection range of the base 2 in the base. The bottom of the inner seat 2 of the stand is open, the inner seat 2 of the stand is directly abutted against the inner bottom surface of the casing 1, the inner seat 2 of the stand comprises an inner seat body 23 and an upper extension part 24 arranged on the inner seat body 23, the upper extension part laterally shields the first air outlet 1121, namely, the exhaust pipe 4 is entirely arranged in the inner seat 2 of the stand in the scheme. Therefore, the whole exhaust pipe 4 can be bent in the inner seat 2 of the engine base for multiple times, on one hand, the inner seat 2 of the engine base can completely separate noise of the exhaust pipe, and the structure similar to a sound-proof cover is formed by the inner seat of the engine base; on the other hand, the inner seat of the machine seat is bent for many times to prolong the propagation path of the wind, change the propagation direction of the wind and weaken the energy of the wind, thereby achieving the effect of reducing the noise.

Example 2: the difference from embodiment 1 is that the bottom surface of the inner seat 2 of the stand is not completely opened, i.e. the bottom surface of the inner seat 2 of the stand is provided with a bottom plate, an air duct outlet 21 is provided on the bottom plate, and the exhaust duct 4 is connected with the second air outlet 3 provided on the bottom surface of the casing through the air duct outlet 21. Compared with the embodiment 1, the scheme is beneficial to avoiding the vibration noise when the exhaust pipe is in exhaust to the bottom surface of the shell by directly contacting the exhaust pipe with the bottom surface of the shell through the bottom plate. Thus, the exhaust noise of the exhaust pipe can be further improved.

Example 3: the difference from embodiment 2 is that the air duct outlet is disposed on the side wall of the inner seat 2 of the machine base, the exhaust duct 4 is connected with the second air outlet 3 through the air duct outlet 21, and the second air outlet 3 is disposed outside the plumb projection range of the inner seat of the machine base and is disposed on the side wall of the machine shell. In this scheme, the bottom surface of the inner seat 2 of the stand is not particularly limited as to whether it is open or semi-open. Because the side wall of frame inner seat 2 and casing all can possess certain clearance generally, consequently exhaust duct 4 comes out from the wind channel export after, can also buckle in this clearance to the exhaust route of further extension wind, and then weaken the noise of wind, make the perception of wind that comes out from second air outlet 3 for the user lower, experience effect is better.

In a preferred embodiment, by setting the inner seat 2 of the machine base to be a closed bottom surface, a closed space is better formed in the inner seat 2 of the machine base, and the noise blocking effect on the exhaust pipe 4 is better. On the other hand, the closed bottom surface can also avoid the contact between the exhaust pipe and the inner bottom surface of the shell, and the vibration generated by the exhaust pipe is directly transmitted to the outside of the shell. That is, in this embodiment, the second air outlet 3 is disposed on the side wall of the housing 2.

In a preferred embodiment, the exhaust duct 4 includes a reducing section 421, and the reducing section 421 is disposed in the housing 2. Under this scheme, through setting up reducing section 421 for when the wind flows through reducing section 421, meet the narrower part of diameter and can gather the wind pressure, be used for releasing the wind pressure when meeting the wider part of diameter, reduce the sound of wind whistle. On this basis, in order to further reduce the overall noise of the exhaust duct, the variable diameter section 421 is further disposed in the housing inner seat 2, and the variable diameter section 421 is blocked by the housing inner seat 2.

In one embodiment of the present utility model, the exhaust duct 4 is provided with a reducing section 421, and the reducing section 421 achieves the noise reduction effect. It should be noted that, whether the variable diameter section 421 is provided in the housing inner 2 is not particularly limited, and the variable diameter section 421 belongs to the variable diameter section 421 as long as the diameter of the exhaust duct 4 is significantly changed, and the following embodiments of the variable diameter section 421 are provided:

Embodiment 1: referring to fig. 12 and 13, the side wall of the variable diameter section 421 of the exhaust duct 4 is corrugated, and one end of the variable diameter section 421 is connected to the first extension section 491. By arranging the corrugated side wall of the variable diameter section 421, on one hand, the corrugated variable diameter section 421 is beneficial to the extension or contraction of the exhaust pipe 4; on the other hand, when the sound wave passes through the reducing section 421, the propagation direction of the sound wave can be continuously changed through the waves with different directions, and when the sound wave collides with the wave surface, the energy of the sound wave can be weakened, so that the direction of the sound wave is continuously changed and the sound wave is weakened, and the wind noise is reduced.

More specifically, one end of the exhaust duct 4 is connected to the fourth extension segment 494 through the third bending segment 483, an anti-trip 4221 is provided on the outer surface of the fourth extension segment 494, and a spigot rib 31 (refer to fig. 5) is provided on the second air outlet 3, and the anti-trip 4221 is in plug-in fit with the spigot rib 31 of the second air outlet 3, so as to realize reliable connection between the exhaust duct 4 and the second air outlet 3. The other end of the reducing section 421 is provided with a matching section 422, the outer surface of the matching section 422 is also provided with an anti-tripping 4221, and the matching section 422 is connected with the first air outlet 1121. Specifically, when the protruding portion 1122 is provided at the first air outlet 1121, the engaging section 422 is in plug-in engagement with the protruding portion 1122 through the anti-release 4221, i.e. the engaging section 422 partially penetrates into the inner cavity of the protruding portion 1122; when the exhaust duct 4 includes the hard duct 41 and the hose 42 connected to the hard duct 41, the reducing section 421 and the fitting section 422 are disposed on the hose 42, and the fitting section 422 is connected to the hard duct 41 in a fitting manner, so as to connect the hose 42 to the hard duct 41, and then the hard duct 41 is connected to the first air outlet 1121.

Embodiment 2: referring to fig. 10, the reducing section 421 of the exhaust duct 4 includes an air inlet section 43, a buffer section 45, a shrinking section 46 and a pressure reducing section 47, a transition section 44 is connected between the air inlet section 43 and the buffer section 45, a transition section 44 is arranged between the buffer section 45 and the shrinking section 46, and a transition section 44 is arranged between the shrinking section 46 and the pressure reducing section 47. Wherein the diameter of the inlet section is smaller than the diameter of the buffer section 45, the diameter of the buffer section 45 is larger than the diameter of the shrinkage tube section 46, and the diameter of the shrinkage tube section 46 is smaller than the diameter of the decompression section 47; the length of the inlet section is smaller than the length of the buffer section 45, the length of the buffer section 45 is larger than the length of the shrinkage section 46, and the length of the decompression section 47 is larger than the length of the shrinkage section 46.

Because the exhaust pipe 4 needs to be connected with the first air outlet 1121, the side wall of the inner seat 2 of the machine base needs to be avoided, and resonance between the exhaust pipe 4 and the inner seat 2 of the machine base is avoided. Thus, the diameter of the inlet section is set smaller so that the exhaust duct 4 can be arranged in a smaller space. After the wind from the first air outlet 1121 passes through the inlet section, relatively large wind pressure is associated in the inlet section, so that the buffer section 45 connected with the inlet section is large in diameter and long in length and is used for releasing the energy of the wind, reducing the wind pressure and the whistle of the wind, and further reducing the noise. The transition section 44 connected between the inlet section and the buffer section 45 is used for wind transition, so that strong wind coming out of the inlet section can be prevented from being instantaneously and rapidly released, and stronger impact noise is generated. After the buffer section 45 passes, the diameter of the contracted pipe section 46 is smaller than that of the buffer section because the reinforcing ribs on the inner seat 2 of the engine seat need to be avoided, and the transition section 44 connected between the buffer section and the contracted pipe section 46 also plays a role in transition. The pipe shrinking section 46 is beneficial to strengthening wind pressure, so that when the wind passes through the pressure reducing section 47, the wind speed is further reduced, the butt joint of the large-caliber buffer section is realized, the energy of secondary release of wind is realized, the wind pressure and the whistling sound of wind are reduced, and the effect of secondary noise reduction is further realized.

In one embodiment of the present utility model, the reducing section 421 is configured to be capable of extending and contracting along the axial direction of the reducing section 421, so that the space of the casing 1 can be reasonably extended or contracted to adapt to the casing 1, and the adaptability is better. The telescopic variable diameter section 421 may be any of embodiments 1 and 2 described above.

Under one embodiment of the utility model, the support framework for supporting the exhaust pipe 4 is arranged inside the exhaust pipe 4, so that the condition that the flexible exhaust pipe 4 is closed when being bent is avoided, the hot air is ensured to be smoothly discharged out of the shell 1, and the heat dissipation effect of the brushless motor 11 is improved. Meanwhile, the supporting framework is arranged to extend into the reducing section 421, so that the condition that the reducing section 421 is closed is further avoided.

The cross arrangement in the vertical direction means that the central axis of the first air outlet 1121 and the central axis of the second air outlet 3 are arranged in a cross manner in a top view of the food processor.

By arranging the central axis of the first air outlet 1121 and the central axis of the second air outlet 3 to be vertically crossed, the exhaust pipe 4 is at least required to be bent downwards and then bent transversely towards the second air outlet 3; or, the exhaust pipe 4 is firstly bent transversely to be positioned above the second air outlet 3 and then bent downwards to be connected with the second air outlet 3.

One end of the exhaust pipe 4 is in sleeve joint with the protruding part 1122, and the exhaust pipe 4 is conveniently communicated with the first air outlet 1121 through the protruding part 1122. Without the protruding portion 1122, the exhaust duct 4 needs to extend into the air inlet 1111 to be installed, and the exhaust duct 4 easily interferes with the motor body.

It can be understood that the exhaust duct 4 and the protruding portion 1122 can be reliably connected by binding and rolling the protruding portion 1122, that is, the exhaust duct 4 is first sleeved outside the protruding portion 1122, and then the two are bound by rolling the protruding portion 1122.

Because the brushless motor 11 has a smaller volume 1, particularly, the axial height is flattened greatly, the expensive cost of changing the mold is saved in order not to change the shape of the original casing 1. Under one embodiment of the present utility model, referring to fig. 1 and 4, a base inner seat 2 is disposed below the lower end cover 112, one end of the base inner seat 2 is connected to the bottom surface of the casing 1, the other end is fixedly connected to the upper end cover 111 or the lower end cover 112, and a receiving cavity for receiving the exhaust duct 4 is formed between the outer sidewall of the base inner seat 2 and the inner sidewall of the casing 1.

Of course, in order to reduce the movement noise between the support post 22 and the inner bottom surface of the casing 1, the support post 22 may be provided as a soft member, such as a silicone member.

Further, in a preferred embodiment, referring to fig. 4, the inner seat 2 of the stand extends upward to at least enclose the first air outlet 1121, and an air duct outlet 21 through which the exhaust duct 4 passes is provided on a side wall of the inner seat 2 of the stand. Since the flow rate of the air discharged from the first air outlet 1121 is relatively fast, the radial force applied to the upper and lower end caps 112 of the brushless motor 11 is also maximized, which is one of the core factors for causing the radial wobble of the brushless motor 11. Therefore, in order to further improve the installation stability of the brushless motor 11 and the inner housing 2, in this embodiment, the inner housing 2 extends upward to enclose the first air outlet 1121, so as to increase the height of the inner housing 2 and the brushless motor 11 along the axial overlapping insertion fit, and further improve the reliability of the inner housing 2 in radial limitation of the brushless motor 11. Meanwhile, since the exhaust duct 4 is connected to the first air outlet 1121, in order to facilitate the exhaust duct 4 to pass through and be accommodated in the accommodating cavity to be connected to the second air outlet 3, an air duct outlet 21 for passing through the exhaust duct 4 must be provided on the side wall of the inner seat 2 of the machine base. It should be noted that, in a specific embodiment, if the first air outlet 1121 is disposed on a side wall of the lower end cover 112, the base inner seat 2 extends upward to at least cover the lower end cover 112, so as to cover the lower end cover 112 completely, which is not limited, so long as the first air outlet 1121 is covered; if the first air outlet 1121 is disposed on the side wall of the upper end cover 111, the base inner seat 2 extends upward to at least cover the upper end cover 111, so as to cover the upper end cover 111 completely, which is not limited, so long as the first air outlet 1121 is covered.

In one embodiment of the present utility model, referring to fig. 7, in order to prevent the exhaust duct 4 from falling down under the action of gravity and falling out of connection with the first air outlet 1121, an air duct outlet 21 is provided to support the exhaust duct 4, so as to reduce the risk of the exhaust duct 4 slipping obliquely downward. There is no limitation on whether the exhaust duct 4 is entirely soft or partially soft.

Therefore, in one embodiment of the present utility model, in order to avoid that the exhaust duct 4 contacts with the cavity wall of the accommodating cavity, and the vibration generated by the exhaust duct 4 is transmitted to the cavity wall of the exhaust duct 4, that is, to the side wall of the housing inner seat 2 and the housing 1, so that the user may feel hands tingling during use, the accommodating cavity is in clearance fit with the exhaust duct 4.

In one embodiment of the present utility model, the exhaust duct 4 includes a spiral surrounding section, and the length of the exhaust duct 4 is extended and the tortuosity of the exhaust air is changed by arranging the spiral section, so as to achieve the effect of noise reduction. Moreover, the spiral surrounding section is arranged to extend obliquely downward so as to gradually approach the second air outlet 3.

After the hot air rapidly flows into the first extension part 491, one end of the second extension part 492 is transversely bent relative to the first extension part 491 to form a first bending part 481 therebetween, so as to realize the conversion of the flow path of the hot air, and the hot air is flexibly collided and weakened in the first bending part 481, thereby reducing the noise of the flowing of the hot air. Then, after the flexibility weakening effect of the first bending section 481, a second extending section 492 is provided again in order to accelerate the heat radiation efficiency. Then, one end of the third extension 493 is bent vertically downward with respect to the other end of the second extension 492 to form a second bending section 482 therebetween, so that the second bending section 482 performs a secondary flexible collision and attenuation on the wind coming out of the second extension 492 to secondarily reduce noise of the wind flow. And the third extension 493 is bent vertically downwards to further extend the exhaust path of the exhaust duct 4 on the one hand and to be close to the second air outlet 3 on the other hand. Then, the third bending section 483 is formed between the end of the fourth extending section 494 and the other end of the third extending section 493 by bending transversely relative to the other end of the third extending section 493, so that the third bending section 483 performs three times of flexible collision and weakening on the wind exiting from the third extending section 493, and noise of wind flowing is reduced again. And the fourth extension 494 is connected with the second air outlet 3, can be with seeing this flexible collision, weakening the wind after, derive the second air outlet 3 fast, can bring the sensation of giving the user the light voice, can wind-guiding fast again, promote radiating efficiency. The scheme achieves good noise reduction effect through repeated circulation of rapid wind guiding-flexible collision and weakening, and meanwhile heat dissipation efficiency cannot be delayed.

In one embodiment of the present utility model, the reducing section 421 is disposed between two adjacent bending sections 48. The two bending sections 48 are used for continuously changing the flow direction of the wind direction, and the reducing section 421 is arranged between the two bending sections 48, so that when the wind flows through the reducing section 421, wind pressure is gathered when encountering a part with a narrower diameter, and the wind pressure is released when encountering a part with a wider diameter, and the sound of wind whistling is reduced.

In one embodiment of the utility model, based on a food processor with a water tank 15, the food processor further comprises a cup body 13 connected with the cup body 132, wherein a liquid receiving cup 16 and a residual water box 17 positioned at one side of the liquid receiving cup 16 are arranged below the cup body 132. The liquid receiving cup 16 and the residual water box 17 are two separate pieces, and are not particularly limited. The working principle is as follows: the water in the water tank 15 is added according to the food amount added in the cup body 13 and the water amount required by the corresponding menu, the crushing knife 131 is driven by the motor to prepare slurry, and the slurry is discharged into the liquid receiving cup 16 through 132 after the slurry is prepared. After the slurry is discharged, water is again fed to clean the cup body 13, and cleaning water is discharged into the residual water box 17 through 132 after the cleaning is finished.

Specifically, in this scheme, seat 2 is located connect the liquid cup 16 with between the exhaust pipe 4 in the frame, the overlook direction of food processor includes the long axis direction of horizontal extension, connect liquid cup 16, seat 2 and exhaust pipe 4 to set gradually along the long axis direction. It is known that when a user uses the food processor, the user often places the food processor in a position where the liquid receiving cup 16 is opposite to the user, so as to conveniently take the liquid receiving cup 16. Therefore, in order to avoid that the liquid receiving cup 16 is too close to the exhaust pipe 4 so that wind noise in the exhaust pipe 4 is closer to a user, the liquid receiving cup 16 and the exhaust pipe 4 are separated by the inner seat 2 of the machine base. Meanwhile, in order to further lengthen the distance between the exhaust duct 4 and the liquid receiving cup 16, the food processor is provided with a long axis direction (i.e., refer to the X axis in fig. 9) extending transversely and a short axis direction (i.e., refer to the Y axis in fig. 9) perpendicular to the long axis direction when seen in a plan view, and the liquid receiving cup 16, the base inner seat 2 and the exhaust duct 4 are sequentially provided along the long axis direction.

Further, the food processor further comprises a water tank 15 and a tank mounting bracket 14 for mounting the water tank 15, and the accommodating cavity is located between the base inner seat 2 and the tank mounting bracket 14. Through setting up water tank 15, can add water automatically when realizing the preparation food material, food processor is more intelligent, and the success rate of user's preparation is higher. On the basis, the water tank mounting frame 14 is arranged outwards for mounting the water tank 15, and the water tank mounting frame 14 is inwards used for enclosing with the base inner seat 2 to form a containing cavity, so that the water tank mounting frame 14 is two-purpose and cost-saving.

In one embodiment of the present utility model, referring to fig. 8, the second air outlet 3 is disposed below the tank mount 14, and the exhaust duct 4 includes an extension section 49 below the tank mount 14, and the diameter of the extension section 49 is smaller than the plumb height L4 between the bottom surface of the tank mount 14 and the inner bottom surface of the cabinet 1, so as to avoid interference between the exhaust duct 4 and the tank mount 14.

In one embodiment of the present utility model, if the brushless motor 11 is placed short, the position of the slurry discharging pipe is also adapted to be short, so that the lateral dimensions of the liquid receiving cup 16 and the residual water box 17 are lengthened due to the short length of the liquid receiving cup 16 and the residual water box 17, thereby affecting the lateral dimension of the whole machine (i.e., the X-axis dimension with reference to fig. 9). Therefore, the scheme is to further solve the working noise generated by the brushless motor 11 on the premise of not expanding the occupied space of the whole machine.

Specifically, referring to fig. 9, a plumb height L1 of the central axis of the first air outlet 1121 from the central axis of the second air outlet 3 is between 10 cm and 18 cm. By setting the L1 between 10 cm and 18 cm, the exhaust duct 4 can have a longer length to lengthen the path length of the exhaust air. When the plumb height (i.e., L1) of the central axis of the first air outlet 1121 from the central axis of the second air outlet 3 is greater than 18 cm, the center of gravity of the brushless motor 11 is higher, and the working stability of the whole machine is reduced. When the plumb height (i.e., L1) of the central axis of the first air outlet 1121 from the central axis of the second air outlet 3 is smaller than 10 cm, the total length of the exhaust duct 4 is limited, which affects the reduction of wind noise, and the liquid receiving cup 16 and the residual water box 17 are made to be short and long in lateral distance, which affects the lateral dimension of the whole machine (i.e., refer to the X-axis dimension of fig. 9).

Under one embodiment of the present utility model, referring to fig. 9, a space extending transversely is provided for the exhaust duct 4 by a transverse distance L3 between the first air outlet 1121 and the second air outlet 3 along the axial direction of the first air outlet 1121 being between 35 and 45mm, which is helpful for prolonging the total length of the exhaust duct 4, further lengthening the propagation path of wind noise, weakening the energy of wind, and achieving the effect of noise reduction. Moreover, the transverse space is large, so that the probability of touching the exhaust pipe 4 with the inner seat 2 of the machine base and the side wall of the machine shell 1 can be reduced. When L3 is larger than 45mm, although the probability of touching the exhaust pipe 4 with the inner seat 2 of the machine base and the side wall of the machine shell 1 can be reduced, the length of the whole food processor along the X-axis direction can be very long due to overlarge transverse space, and the carrying and the use of a user are affected; when L3 is less than 45mm, the transverse space is smaller, and the exhaust pipe 4 is easy to touch and flatten with the inner seat 2 of the machine base and the side wall of the machine shell 1, so that the exhaust effect is affected.
