Description

Mill type juice and crusher body {body for juice or crush apparatus}

The present invention relates to a mill-shaped juice-and-crusher main body, and in particular, the inlet of the case and the outlet of the base plate are formed with an air circulation path by an external suction fan of the motor, and a pair of foot having an elastic member made of rubber is provided. The installed motor housing is fixed to the base plate, the drive shaft is disposed directly above the motor shaft, and the drive shaft is arranged in parallel with the driven shaft, and a gap is formed in the coupling portion of the case and the base plate. The present invention relates to a millstone-type juice-and-crusher body in which an elastic member made of rubber is interposed between a first support means for supporting a motor housing on a plate and a second support means for supporting a reduction gear device in a case.

In general, as shown in FIG. 9, the juicer is largely fitted into the main body 100, the screw rod 120, the screw rod 120, the screw rod 120, the screw rod 120 and the juice container 130 It consists of a housing 140, a cap 150 is coupled to the housing 140, the discharge cap 160 is coupled to the cap 150. The rotating shaft 122 of the screw rod 120 is coupled to the main body 100 to receive the rotational power.

One end of the housing 140 is coupled by a binding ring 114 of the main body 100, and the other end supports the cap 150. In the housing 140, an inlet 143 is formed on the upper surface, and a juice outlet 146 is formed on the lower surface. The inlet 143 is preferably provided with a hopper 144 to facilitate the injection of the adherent juice. The residue is discharged to the outside through the discharge cap 160 coupled to the cap 150. Here, it will be apparent that the juice container 130 may serve as a grinder when the juice container 130 intersects in a grinding container (not shown).

Through such a configuration, the juicer is a device for transferring juice to the outside through the juice container 140 in the order of grinding and pressing while transferring the adhered juice along the screw rod 120.

As described above, the main body 100 is coupled to the motor 101, the motor support motor housings 103a and 103b, and the motor housing 103b, and receives the rotational power of the motor 101 to receive a screw. It consists of a reduction gear device 170 to be transmitted to the rod 120, a base plate 107 on which the motor housings 103a and 130b are mounted, and a case 109 coupled to the base plate 107.

The motor 101 is provided with a built-in fan, in detail a discharge fan (not shown) on both sides of the motor shaft (not shown). That is, when the discharge fan rotates, air in the case 109 flows and is discharged to the discharge port 107a of the base plate 107. Motor 101 is a four-pole motor so that the rotation speed of the screw rod is usually about 80 RPM, the rotation speed of the motor shaft is about 1800 RPM, the deceleration of this rotation speed is achieved through the gear train of the reduction gear device 170.

As shown in FIG. 11, the reduction gear device 170 coupled to the motor housing 103b includes a reduction gear housing 171 and a cover 173 that largely surround the reduction gear array. The reduction gear housing 171 includes a drive gear 177 that meshes with a motor shaft (not shown), a drive shaft 175 supporting the drive gear 177, a drive pinion 178 installed on the drive shaft 175, and a drive pinion. The driven gear 181 meshing with the driven gear and the driven shaft 179 supporting the driven gear 181 are mounted. The drive shaft 175 and the driven shaft 179 are rotatably supported by bearings (not shown) supported by the reduction gear housing 171 and bearings 183 and 185 supported by the lid 173.

In addition, the reduction gear housing 171 is formed with a protruding plate 170a protruding downward. The protrusion plate 170a is provided with a through hole through which the male screw body 112a is fitted. The base plate 107 is provided with the bracket 110 in the position which opposes this protrusion plate 170a. The bracket 110 is formed with a channel 110b at a position facing the through hole. Therefore, the nut 112b is interposed with the washer while the body of the male screw body 112a fitted to the protrusion plate 170a in the state where the protrusion plate 170a and the bracket 110 overlap each other is supported on the bottom of the channel 110a. By engaging with, the power train is fixed to the base plate 107. On the other hand, the circumferential housing of the socket 170b of the reduction gear device 170 is fixed to the front surface of the case 109 through a support plate coupled with the binding ring 114 (see FIG. 1).

However, the above-described main body 100 has the following problems.

(1) The case 109 and the base plate 107 are coupled to each other so that the rotational vibration of the motor 101 is transmitted to the base plate 107 through the protrusion plate 105a, and the reduction gear device 105 Will be delivered to the case 109 through. The transmitted vibration is reinforced in contact with each other to generate a severe friction sound and tremor phenomena may give the user an inconvenience such as stress or durability of the body.

(2) Since the protrusion plate 105a and the bracket 110 are made of hard materials, friction occurs with each other due to the vibration of the motor 101, and the vibration is carried out through the base plate 107 through the bracket 110. Can be very noisy.

(3) In the fastening method of the male screw body 112a and the nut 112b, loosening of the nut 112b may occur due to vibration or friction. Therefore, the fixing of the power transmission device may be unstable, adversely affecting the main body, and significantly lowering the green juice efficiency.

(4) The vibration of the motor 101 may be transmitted to the case 109 through the reduction gear device 170 to generate noise.

(5) Since the air exhaust structure only circulates with the air inside the case 109 to cool the motor, the air circulation structure does not achieve one cycle, and thus the cooling efficiency may be significantly reduced. In particular, when the screw rod 120 is not rotated by the adherent juice, the motor is overloaded, and a lot of heat is generated. The heat of the generated heat may not be enough to cause damage to the motor. In particular, since the air discharge passage is not formed on the front surface of the motor housing 103b in which the reduction gear device 170 is installed, the air sucked into the motor may be stagnant and the cooling efficiency may be significantly reduced. In addition, since the case 109 and the base plate 107 are coupled to each other, it is difficult to discharge the air to the combined portion, and the motor vibration mode of the base plate 107 is transmitted to the case 109 as it is, thereby reducing the friction sound. Noise may occur.

(6) Since the protruding plate 105a and the bracket 110 protrude from each other, the height of the case 109 may be increased to increase the size of the main body.

(7) As shown in FIG. 11, the motor shaft, the drive shaft 175, and the driven shaft 179 are arranged in a zigzag manner so that the volume of the reduction gear housing 170 becomes large as a whole. Accordingly, the grease filling distance inside the reduction gear housing 170 is long, so that a large amount of grease needs to be injected in order for the grease to stay in the gear.

(8) In order to obtain the rotational speed of the screw rod of 80RPM at 1800RPM motor shaft rotation speed with four-pole motor, the number of teeth of the reduction gear is relatively increased and the pitch circle diameter of the gear becomes large. Accordingly, the size of the reduction gear housing 170 may also become a factor.

(9) Since the lid 173 is fitted to the rear surface of the reduction gear housing 171, a component called the lid 173 is required, and the number of steps for fitting the lid 173 is further increased, thereby reducing economic efficiency and productivity. Can be.

(10) As the reduction gear housing 171 increases in volume, the front surface of the motor housing 130b is almost blocked by the cover 170, so that it is inevitable to rely on holes formed in the side surfaces to dissipate the heat of the motor. Therefore, there is a fear that a failure due to overheating of the motor may occur due to a problem in smooth cooling of the motor.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a mill-shaped juice-and-crusher main body having a structure capable of reducing noise and vibration while achieving overall miniaturization while increasing the cooling efficiency of the motor.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, and like reference numerals refer to like elements, and detailed description thereof will be omitted.

1 is a perspective view showing a mill-shaped juice-and-crusher body according to a preferred embodiment of the present invention, Figure 2 is a bottom view of Figure 1, Figure 3 is a rear view of Figure 2. As shown in FIGS. 1 to 3, the main body 10 of the present embodiment includes a case 70 and a base plate 60 having a large appearance.

The front of the case 70 is seated on the front of the reduction gear device 40 described below, the outlet hole 70a through which the socket 45 is drawn out is drilled, and the switch is provided on the upper surface. A packing 49 is preferably provided between the inner surface of the case defining the drawing hole 70a and the front surface of the reduction gear device 40 seated at the drawing hole. By adopting the structure of this packing 49, the vibration of the motor 20 can suppress the transmission to the case 70 through the reduction gear device 40 as much as possible.

In addition, the support plate 15 and the reduction gear device 40 coupled to the binding ring 15 are coupled to the male screw body 17a and the female screw 17b so that the front surface of the reduction gear device 40 is drawn out 70a. It is firmly seated in the seat. At this time, the packing 19 is installed between the support plate 15 and the case of the outlet hole outer surface, so that the vibration transmitted to the case 70 can be absorbed.

As shown in FIG. 3, a rear surface of the case 70 is provided with a suction port 75 having a plurality of slots formed therein. The base plate 60 is fastened to the case 70 in a state where the motor housing 30 described later is mounted. As shown in FIG. 2, the base plate 60 is provided with an outlet 65 in which a plurality of slots are drilled.

Meanwhile, as shown in FIG. 2, a gap 60a is formed at an edge portion where the base plate 60 and the case 70 are coupled to each other. The gap 60a is a friction sound that collides with each other when the vibration according to the driving of the motor 20 is transmitted to the base plate 60 through the foot 90 or to the case 70 through the reduction gear device 40. Can be reduced as much as possible. In addition, the gap 60a can further expand the air discharge area in the air circulation passage described below, thereby improving the cooling efficiency of the motor.

Hereinafter, the structure of the power transmission device for transmitting the rotational force to the screw rod 120 will be described.

Figure 4 is an exploded perspective view of the power transmission device and the base plate of the present embodiment, Figure 5 is a cross-sectional view taken along the line AA of Figure 4, Figure 6 is a side view showing the main part cut in the power transmission device of Figure 4, FIG. 7 is a cross-sectional view of the elastic member II of FIG. 4, and FIG. 8 is an exploded perspective view showing the rear surface of the power transmission device of the present embodiment. 4 to 8, there is a motor 20 to which power is applied. The motor 20 is provided with motor shafts 21 and 25 protruding forward and rearward. The front motor shaft 21 is a helical type gear that transmits rotational power to the reduction gear device 40, and the rear motor. The shaft 25 is provided with a suction fan 50a described later. It goes without saying that the front motor shaft 21 and the rear motor shaft 25 are integrally formed. The motor 20 is supported by the motor housing 30.

On the other hand, in the embodiment of the motor 20, a six-pole motor is used so that the rotational speed of the motor shaft is 1200 RPM. This is to reduce the size of the reduction gear device 40 to be described later while reducing the vibration of the motor itself. That is, the rotation speed of the screw rod 120 is about 80 RPM as described above. Therefore, in order to reduce from 1200RPM to 80RPM, it is necessary to adjust the gear ratio of the reduction gear train. At this time, since the number of teeth of each gear is relatively small because the motor shaft of the present embodiment is slower than the conventional motor shaft, the pitch circle diameter of the gear is reduced. Therefore, it is possible to reduce the size of the housing surrounding the reduction gear.

The motor housing 30 is largely composed of a rear motor housing 30a and a front motor housing 30b. Each of these motor housings 30a and 30b is fitted to the rear and front surfaces of the motor 20 and is coupled by the male screw 37.

As shown in FIGS. 6 and 8, the rear motor housing 30a has a structure surrounding the rear side and some side surfaces of the motor 20 while the rear motor shaft 25 protrudes. In addition, the rear air housing 30a is formed with a rear air inflow passage 31a at a position opposite to the suction port 75.

A suction fan 50a is installed on the rear motor shaft 25 so that air is injected into the rear air inflow passage 31a. This suction fan 50a is preferably installed between the rear air inflow passage 31a and the suction port 65 (that is, the suction fan of the present embodiment is external). In addition, it is preferable that the guide member 35a shown in FIG. 6 and FIG. 8 is provided in the circumferential surface of the suction fan 50a so that the suction fan 50a can rotate. That is, the guide member 35a blocks the outer circumferential surface of the suction fan 50a from the outside while protruding in the direction along the rotation center line of the motor shaft from the rear motor housing 30a. Therefore, the air sucked through the suction fan 50a is prevented from escaping between the suction fan 50a and the rear motor housing 30a, so that the air suction rate into the rear air inflow passage 31a can be increased as much as possible. .

In addition, an opening 31b is drilled in the front motor housing 30b as shown in FIG. The opening 31b may be installed as the sizes of the reduction gear housings 40a and 40b described below are reduced, and through this configuration, the heated air in the motor 20 is transferred to the outside through the front motor housing 30b. It can be discharged more efficiently. Therefore, this opening part 31b functions as the air discharge passage 31b which can raise the cooling efficiency of a motor. In addition, it is preferable that the side air discharge passages 33a and 33b are formed in each of the motor housings 30a and 30b.

On the other hand, a discharge fan 50b is installed at a position opposite to the front air discharge passage 31b in the front motor shaft, part of which is accommodated in the front motor housing 30b. The discharge fan 50b is incorporated in the front motor housing 30b. By installing the discharge fan 50b, the air circulation speed can be improved.

Looking at the cooling system of the motor through such a configuration as follows.

When power is applied to the motor 20, the front motor shaft and the rear motor shaft 25 formed integrally rotate. As the motor shaft 25 rotates, the suction fan 50a and the discharge fan 50b also rotate. Therefore, as illustrated in FIG. 1, external cold air IA flows into the case 70 through the inlet 65. The introduced air is introduced into the motor 20 through the suction fan 50a, the guide member 35a, and the rear air inlet passages 31a and 33b. The air introduced into the motor 20 is led to the front air discharge passage 31b by the discharge fan 50b while cooling the inside of the motor 20. The air guided to the front air discharge passage 31b is discharged to the outside through the outlet 65 (OA). In addition, the side air discharge passage 33a or 33b also serves to discharge auxiliary heated air. It is preferable that a plurality of legs 80 are installed on the lower surface of the base plate 60 so that the exhaust air OA is smoothly discharged to the outside.

In this way, the rear air suction flow path and the exhaust fan 50b of the suction port 65, the suction fan 50a, the guide member 35a, and the rear air inflow path 31a, the front air discharge path 31b, and the discharge port 65 By forming an air circulation passage consisting of the front air discharge passage to the air discharge passage of the), it is possible to significantly improve the cooling efficiency of the motor (20). The side air discharge passage 33a or 33b may additionally function in the front air discharge passage.

On the other hand, the front motor housing 30b is fixed to the base plate 60 by the first supporting means. That is, a pair of foot 90 is provided in the lower surface of the front motor housing 30b. The foot 90 is not only fixed to the seat 93 of the base plate 60 but also can reduce the height of the motor housing 30, thereby miniaturizing the case 70.

In addition, in order to suppress the vibration caused by the rotation of the motor 20 to the base plate 60 through the foot 90 as much as possible, the rubber having a high vibration or noise absorption rate between the foot 90 and the seating portion 93. It is preferable that the elastic member 91 of the back and the material is interposed.

In addition, in order for the foot 90 to be fixed to the base plate 60 more stably, it is preferable that a support wall 93a is provided around the seating portion 90 opposite to the side of the foot 90. At this time, it is preferable that a side elastic piece 92 such as an elastic member 91 be interposed between the foot 90 and the support wall 93a.

By adopting the configuration of the elastic member 91 and the side elastic piece 92 to the foot 90, the vibration of the motor 20 is transmitted to the base plate 60 to be absorbed as much as possible to quiet the body 10 One operation can be achieved.

In addition, as shown in FIGS. 4 and 7, a flaw 90a is formed in the foot 90, and a groove is formed in the elastic member 91 so that the elastic member 91 is easily assembled and disassembled in the foot 90. A web 91a inserted into and out of 90a, a lower flange 91c interposed between the foot 90 and the seating portion 93, and an upper flange 91b disposed on the upper surface of the foot 90 are configured. In addition, the foot 90 may be simply disposed between the upper flange 91b and the lower flange 91c, and the foot 90 may be fixed up and down. In the center of the elastic member 91, a through hole 91b is formed as shown in FIG. In addition, for disassembly and disassembly of the elastic member 91, the side elastic piece 92 is preferably provided in the lower flange (91c).

The elastic member 91 and the foot 90 configured as described above are fixed to the base plate 60 through the female thread part 95 and the male thread body 97 installed in the seating part 93. That is, in the state in which the elastic member 91 is assembled to the foot 90, the fixing is completed by the fastening of the female thread part 95 and the male thread body 97 inserted into the through hole 91d of the elastic member 91. . At this time, interposing the washer 98 at the time of fastening the male screw body 97 can be more securely fixed while preventing damage to the elastic member 91.

Thus, the foot 90 is fixed up and down by the elastic member 91, and back and front is fixed by the support wall 93a; The elastic member 91 may be fixed back and forth by the female thread portion 95 and fixed by the groove 90a and the support wall 93a.

On the other hand, the rib 90 is formed with the rib 90b. This rib 90b not only reinforces the strength of the edge portion of the foot 90, but also suppresses the left and right movement of the upper flange 91b according to the gap between the groove 90a and the web 91a, so that the motor housing can be viewed as a whole. It can play a more secure role.

As shown in FIG. 5, the reduction gear device 40 is a first reduction gear housing 40a and a second reduction gear housing 40b that are largely coupled to the front motor housing 30b. It looks like.

The first reduction gear housing 40a is integrally formed with the front motor housing 30b and supports the first bearing 42a and the second bearing 48a. Therefore, the support of the bearings 42a and 48a can be simplified, and the assembly with the second reduction gear housing 40b can be convenient. Further, the first reduction gear housing 40a is formed with a lead hole 44 through which the motor shaft 21 is drawn out.

The 2nd reduction gear housing 40b also supports the 1st bearing 42b and the 2nd bearing 48b in the position which opposes the bearing 42a, 48a of the 1st reduction housing 40a.

The drive shaft 41 is installed between the first bearing 42a and the first bearing 42b. The drive shaft 41 is provided with a helical drive gear 41a meshed with the motor shaft 21. Next to this drive gear 42a, a helical type drive pinion 41b having fewer teeth is provided.

On the other hand, a driven shaft 47 is installed between the second bearing 48a and the second bearing 48b. The driven shaft 47 is provided with a helical driven gear 47b meshed with the drive pinion 41b. The rotational speed of the driven gear 47b is transmitted to the screw rod 120 through the socket 45 provided at one end of the driven shaft 47.

The motor shaft 21, the drive shaft 41, and the driven shaft 47 are arranged in a vertical arrangement. That is, the drive shaft 41 is provided directly above the motor shaft 21, and the driven shaft 47 is provided in parallel with each other directly above the drive shaft 41. Due to the axis of the vertical arrangement, as shown in the figure, it can be seen that the optimized shape of the reduction gear housings 40a and 40b is an ellipse, and through this elliptical shape, the reduction gear can be arranged in a minimum space. Therefore, since unnecessary space is eliminated inside the reduction gear housings 40a and 40b, the amount of grease injected is reduced, and the scattering distance of the grease is also shortened, thereby reducing the amount of grease injected. Therefore, the grease stays in the gears, so that the noise due to the engagement between the gears can be suppressed to the maximum.

Furthermore, as described above, by using a low speed motor shaft, the number of teeth of the drive gear, the drive pinion, and the driven gear is reduced at least, so that the size of the reduction gear housings 40a and 40b is also reduced. It will be obvious.

The reduction gear device 40 has a support plate 15, a male thread 17a, and a female screw 17b which interact with the binding ring 14 while being disposed in the second support means, that is, the outlet hole 70a of the case 70. ) Is fixed to the case 70. Therefore, the power transmission device can be stably fixed inside the case 70. At this time, the packing 49 is installed as described above, the vibration of the motor is absorbed, it is possible to reduce the transmission to the case 70 to suppress the generation of noise.

As such, the power transmission device mounted on the base plate 60 is accommodated in the case 70, and vibration generated by the driving of the motor is transferred to the base plate through the elastic member 91 and the side elastic piece 92. 60 can be suppressed from transmitting vibrations. For example, even if a small vibration is transmitted to the base plate 60, it can be eliminated through the gap (60a) formed in the coupling portion of the base plate 60 and the case 70. Therefore, quiet operation of the main body can be enabled.

The mill-shaped juice-and-crusher body according to the present invention is not limited to the above-described embodiments, and may be variously modified and implemented within the range permitted by the technical idea of the present invention.

According to the millstone-type juice-and-crusher main body of the present embodiment as described above, the following effects are obtained.

Further comprising a plurality of legs installed in the base plate to form a space in the lower portion, wherein the suction fan is installed in a position opposite to the suction port, the rear motor housing corresponding to the suction fan has a rear air inflow passage And an air circulation passage through which the air is circulated through the suction port, the rear air inlet passage, and the motor by the operation of the suction fan, wherein the first supporting means is installed in the front motor housing. Pair of feet; An elastic member interposed between the foot and the base plate; It consists of a fastening member for fastening the foot to the base plate, the reduction gear device is a drive gear meshed with the motor shaft; A drive shaft provided with the drive gear and disposed parallel to the motor shaft; First bearings rotatably supporting both ends of the drive shaft; A drive pinion installed on the drive shaft; A driven gear engaged with the drive pinion; A driven shaft on which the driven gear is installed and arranged parallel to the drive shaft; Second bearings rotatably supporting both ends of the driven shaft; A first reduction gear housing integrally formed in the front motor housing and supporting the first bearing and the second bearing of the one end while the motor shaft protrudes; It consists of a second reduction gear housing for supporting the first bearing and the second bearing of the other end and coupled to the first reduction gear housing, the motor is a six-pole motor, the rotational speed of the motor shaft is 1200RPM, the base A gap is formed in the edge portion where the plate and the case are coupled to each other, so that air is circulated through the suction port, the rear air inlet passage, and the motor by the operation of the suction fan. By forming a circulation flow path, the outside cold air and the inside of the case, especially the inside of the motor, can be smoothly in and out, which can significantly improve the cooling efficiency of the motor. Can be downsized and the body can be downsized. By absorbing vibration, stable operation of the power mechanism and noise reduction can be obtained. ④ The reduction gear shaft is arranged in a vertical arrangement with the motor shaft, which reduces the size of the reduction gear housing, further promoting the miniaturization of the main body. As the housing's size is smaller, the amount of grease scattered is reduced, which reduces the amount of grease injected, and the distance to fly is short, so that grease stays on the gear at all times, reducing noise due to gearing between gears. ⑥ The first reduction gear housing has a front motor housing. Since it is integrally formed in the body, a separate grease cover is unnecessary, and the number of assembly processes is reduced. ⑦ Less noise and vibration due to low speed rotation compared to conventional 4-pole motors. ⑧ To obtain the same output speed, the number of teeth of the reduction gear is conventional. It is relatively small compared to this, and this makes the pitch circle diameter of the gear smaller. The airway is also smaller, which can contribute to the reduction in the size of the gearbox housing. ⑨ It is possible to remarkably reduce the noise such as the friction sound which is collided with each other by canceling the interaction between the vibration of the motor transmitted to the base plate through the motor housing and the vibration transmitted to the case through the reduction gear device.
