Recently, as interest in health increases at home, the frequency of use of a juicer having a function that an individual can directly make juice from a juice target such as vegetables, grains and fruits and consume it is increasing.

The juicer is a machine that juices fruits or vegetables by pressing through a screw rotation. Since it is usually rotated at a low speed of 80rpm or less, there is little frictional heat, so there is no nutrient destruction, and it has the advantage of low noise generation. The juicer is provided with a motor that transmits rotational power to the screw.

In general, the drive motor for the undiluted solution has a heat dissipation limit by dissipating heat in an air-cooled manner using a fan mounted on the rotor.

Therefore, if the juicer is continuously used at home for more than 30 minutes, the temperature protection device of the drive motor may operate and the drive of the drive motor may be stopped. When the temperature protection device operates once, it takes about 5 to 10 minutes to return to normal operation of the motor, so user complaints may be raised.

In order to solve the above problems, the prior art increases the size of the motor (generally, the motor diameter is extended from 90mm to 120mm) in order to increase the rated use time of the motor for undiluted solution. Efforts were made to improve cooling performance by double mounting below and above, but this caused a new problem in that the weight, size, and design cost of the motor increased.

As used herein, the term “and/or” includes any one or all combinations of the associated listed items.

1 is a perspective view showing the inside of the juicer operated by the drive motor of the present invention.

Referring to FIG. 1 , the juicer 1 according to an embodiment of the present invention includes a housing 10 , a juice drum 20 , a screw 30 , a mesh drum 40 , a brush 50 and a cover 60 . includes

The housing 10 has a hollow column shape, a body portion 11 extending in a vertical direction from the ground, a lower support portion 12 extending along the ground from the lower end of the body portion 11, and disposed on the upper portion of the body portion 11 . and an upper support part 13 provided to support the side of the juice drum 20, and a reduction gear housing 14 extending in parallel with the lower support part 12 between the main body part 11 and the upper support part 13. can

A driving unit 15 is provided inside the main body 11 to generate a driving force and transmit it to the screw 30 , and the driving unit 15 includes a driving motor 100 that rotates and a rotational force from the driving motor 100 . Includes a reducer 17 that receives the transmission.

As the driving motor 100 , an AC motor using an AC power may be generally used, but is not limited thereto. In addition, the diameter of the drive motor 100 may be determined according to the purpose or specification of the juicer 1 . In one example, the diameter of the drive motor 100 may be about 90 mm.

The driving motor 100 may be mounted on the lower portion of the housing 10 to suppress vibration of the juicer 1 and lower the center of gravity. If necessary, the driving motor 100 may be mounted on the upper portion or the middle portion of the housing 10 . The drive motor 100 rotates about a rotational shaft in a direction perpendicular to the ground, and a reducer 17 is connected to the rotational shaft.

The reducer 17 extends from the central portion of the body portion 11 along the reducer housing 14 toward the juicer drum 20 . In one example, the reduction gear housing 14 is generally formed in a disk shape, and a drive shaft 18 connected to the reduction gear 17 protrudes upward at the center thereof. One end of the reducer 17 is connected to an upper end (eg, a rotation shaft) of the driving motor 100 , and the other end extends in a horizontal direction with the ground.

In one example, since the reducer 17 is connected to the upper end of the driving motor 100 , it is configured to be spaced apart from the ground by a predetermined distance. The drive shaft 18 further protrudes upward from the top of the reduction gear 17 . Accordingly, the user can easily mount or detach the juice drum 20 from the housing 10 by freely moving the juice drum 20 upwards or downwards without being disturbed by other components.

According to the above embodiment, since an additional lower space between the reducer 17 and the ground is secured, the degree of freedom in design is improved, and the lower space can be used as a space for collecting juice or residues. In one example, the dregs may be discharged in the lateral direction of the juicer 1 . In another example, the dregs may be discharged vertically downward of the juicer 1 . When the residue is discharged vertically downward of the juicer 1 , the load acting on the driving motor 100 can be reduced, and vibration of the driving motor 100 can also be suppressed.

In one example, the reducer 17 may be configured with a plurality of gears to transmit power from the drive motor 100 to the drive shaft 18 . By using the reinforced gear with enhanced durability as the gear of the reducer 17, the use of the juicer 1 is not limited to household use, but can be used for businesses and stores.

In another example, the reducer 17 may transmit the power of the driving motor 100 to the screw 30 by means of a belt and pulleys. The belt may be configured in various forms, for example, a pen belt, a flat belt, and a V belt may be applied.

According to an embodiment of the present invention, since the durability of the gears constituting the reducer 17 is strengthened, the use of the juicer 1 is not limited to home use, but can be expanded to a commercial product.

A drive shaft 18 protruding upward is provided at the other end of the reducer 17 , and the screw 30 can rotate by the drive shaft 18 . The drive shaft 18 may be formed in various shapes capable of transmitting power to the screw 30 . The screw 30 may be provided inside the juice drum 20 together with the mesh drum 40 and the brush 50 .

The screw 30 rotates by receiving power from the drive shaft 18, and performs a function of compressing or pulverizing the juice target. To this end, a plurality of screw spirals 31 are formed in the screw 30 in contact with the mesh drum 40 . By the screw spiral 31, the juice target is compressed into a narrow gap between the screw 30 and the mesh drum 40 and transferred to the lower side.

The mesh drum 40 has a plurality of mesh holes formed on its side so that the juice generated by the screw 30 can be discharged to the outside of the mesh drum 40 . The mesh drum 40 is not rotated together when the screw 30 rotates. Residues that do not pass through the mesh hole of the mesh drum 40 are separated from the juice and discharged to the outside of the juicer 1 through a residue outlet formed on the lower surface of the juice drum 20 .

On the other hand, the mesh drum 40 may be formed in a form without a mesh ball on the side to be used for grinding. In this case, when the material is input, the material is compressed and pulverized by the mesh drum 40 and the screw 30, but the juice and the residue are not separated and are discharged through the residue outlet. In addition, even in the case of using the juice mesh drum 40 having a mesh hole on the side, the juice outlet can be blocked by using a juice opening/closing mechanism capable of opening and closing the juice outlet, and the juicer can be operated.

In one example, the brush 50 may be disposed between the juicer drum 20 and the mesh drum 40 . The brush 50 includes a brush frame and brush blades. The brush frame is provided to be spaced apart from the juice drum 20 and the mesh drum 40 . The brush blades are formed in a shape protruding in both directions in the radial direction from the side of the brush frame, and when the brush 50 rotates, it sweeps away the juices on the inner surface of the juice drum 20 and the outer surface of the mesh drum 40 . It is possible to separate the debris caught in the mesh ball from the mesh drum (40).

The cover 60 is formed to cover the upper portion of the juice drum 20 , and may include a material input unit 61 for inputting materials and a hopper 62 for guiding the input materials to the juice drum 20 . The lower end of the hopper 62 is formed at an eccentric position from the drive shaft 18 of the juice drum 20 to enable smooth material input when the screw 30 rotates.

In the present specification, a stock solution according to one example has been described. However, a juicer according to another example may be used. For example, a drum (not shown) composed of two modules in which the mesh drum 40 and the brush 50 are omitted and separable from each other may be used instead of the mesh drum 40 . In this case, when two modules are joined, a microscopic gap is formed between them. The juice passes through the crevice and the sludge does not pass through the crevice and moves to the bottom of the drum. In this example, the gap formed between the two modules serves as a mesh hole of the mesh drum 40 .

Hereinafter, with reference to FIGS. 2 to 4 , a driving motor for an undiluted solution equipped with a thermoelectric element cooling module according to an embodiment of the present invention will be described in more detail.

2 is a view showing a driving motor for an undiluted solution equipped with a thermoelectric element cooling module according to an embodiment of the present invention, FIG. 3 is a perspective view showing a cooling module according to an embodiment of the present invention, FIG. 4 is It is a perspective view showing each component constituting the cooling module of FIG. 3 .

2 to 4 , the driving motor 100 according to an embodiment of the present invention rotates by application of current and transmits the generated power to the screw 30 . The driving motor 100 has a cooling module 200 attached to at least a portion of its outer peripheral surface for cooling. The cooling module 200 is configured to generate cool air by supplying current and transmit it to the driving motor 100 .

To this end, the cooling module 200 includes a thermoelectric element 201 that generates cold air by receiving an electric current, a cooling plate 202 that connects the thermoelectric element 201 and the drive motor 100 to allow heat transfer; The thermoelectric element 201 may include a heat sink 203 and a cooling fan 204 that help dissipate heat. The configuration of the cooling module 200 will be described in detail.

The thermoelectric element 201 receives a current through the terminal 2011 to generate cold air, and transmits the generated cold air to the driving motor 100 . In one example, the thermoelectric element may have a rectangular plate shape, and a pair of terminals 2011 are provided in parallel at the bottom to serve as positive (+) and negative (-) poles to receive current.

In one example, the thermoelectric element 201 may include a Peltier semiconductor that generates a Peltier effect. The Peltier semiconductor is composed of at least a pair of n and p-type semiconductors, and one of the n and p-type semiconductors generates heat and the other of the n and p-type semiconductors absorbs heat according to the direction of the current applied to the Peltier semiconductor. (i.e. it creates cold air.)

When the thermoelectric element 201 has a rectangular flat plate shape, when a current is applied to the Peltier semiconductor, one surface absorbs heat and the other surface opposite to the one surface generates heat. By attaching the cooling plate 202 to one surface of the thermoelectric element 201 , the cold air generated from the thermoelectric element 201 is transferred to the cooling plate 202 , and the heat generated through the other surface of the thermoelectric element 201 is transferred to the heat sink 203 . ) can be released to the outside.

The cooling plate 202 is attached to one surface of the thermoelectric element 201 and the outer peripheral surface of the driving motor 100 , and serves as a bridge through which cold air generated from the thermoelectric element 201 flows to the driving motor 100 . When a current is applied to the thermoelectric element 201 , the cold air generated on one surface of the thermoelectric element 201 is transferred to the cooling plate 202 , and finally transferred to the driving motor 100 .

The cooling plate 202 serves to protect the thermoelectric element 201 and serves as a medium for heat transfer between the thermoelectric element 201 and the driving motor 100 . To this end, the cooling plate 202 may be made of a material having high thermal conductivity. For example, the cooling plate 202 may be made of a thermally conductive ceramic material or aluminum that smoothly conducts heat while being less affected by corrosion.

2 and 3 , the cooling plate 202 includes a first contact surface 2021 and a second contact surface 2022 opposite to the first contact surface 2021 .

The first contact surface 2021 is a portion of the cooling plate 202 that is attached to the drive motor 100 . The first contact surface 2021 is attached to the recess 101 of the drive motor 100 . The concave portion 101 has a shape that is recessed in the central portion of the outer peripheral surface of the driving motor 100 in the height direction. It is attached in such a way that the first contact surface 2021 is fitted to the concave portion 101 . Additionally or alternatively, the drive motor 100 and the cooling plate 202 may be screwed together.

The first contact surface 2021 may have a shape corresponding to the shape of the outer circumferential surface of the driving motor 100 in order to widen an area for transferring cold air to the driving motor 100 . In this case, the first contact surface 2021 may surround at least a portion of the outer peripheral surface of the driving motor 100 . Accordingly, the transfer efficiency of cold air to the driving motor 100 may be increased, and the cooling plate 202 may be easily attached to the outer peripheral surface of the driving motor 100 .

That is, cold air is provided while the cooling plate 202 is more closely and widely attached to the driving motor 100 , and accordingly, heat exchange for dissipating heat from the driving motor 100 is more efficiently performed.

The second contact surface 2022 of the cooling plate 202 is a portion of the cooling plate 202 to which one surface of the thermoelectric element 201 is attached. The second contact surface 2022 may have a shape corresponding to one surface of the thermoelectric element 201 to effectively receive the cold air generated by the thermoelectric element 201 .

As an example, when the thermoelectric element 201 has a square plate shape, the second contact surface 2022 may also have a flat square plane shape. Also, a groove corresponding to the shape of the thermoelectric element 201 may be formed on the second contact surface 2022 to prevent the thermoelectric element 201 from being separated. By inserting the thermoelectric element 201 into the groove, the thermoelectric element 201 can be easily attached to the cooling plate 202 , and heat transfer from the thermoelectric element 201 to the cooling plate 202 is also performed efficiently.

Preferably, the cooling plate 202 may be made of a thermally conductive ceramic or aluminum material, which has a low effect of corrosion and conducts heat smoothly. Accordingly, there is an advantage that can respond even if the shape of the drive motor 100 is formed in a shape other than the cylindrical shape mentioned above as an embodiment according to another embodiment.

On the other hand, an insulating material may be coated on the outer surface of the cooling plate 202 except for the first and second contact surfaces 2021 and 2022 so that the cold air generated by the thermoelectric element 201 can be transmitted to the driving motor 100 as much as possible. have. Accordingly, the cool air generated by the thermoelectric element 201 may be transmitted to the driving motor 100 as much as possible without being radiated to the outside.

The heat sink 203 may be attached to the other surface of the thermoelectric element 201 . As described above, according to the Peltier effect, one surface of the thermoelectric element 201 attached to the cooling plate 202 absorbs heat and the other surface of the thermoelectric element 201 generates heat. The heat sink 203 smoothly discharges heat generated on the other surface of the thermoelectric element 201 to the outside.

In one embodiment, the heat sink 203 and the cooling plate 202 may be screwed to each other by providing screw holes at positions corresponding to each other. In this case, the heat sink 203 and the cooling plate 202 are screwed together and the heat sink 203 - the thermoelectric element 201 including the thermoelectric element 201 attached to the second contact surface 2022 of the cooling plate 202. - The cooling plates 202 are coupled to each other.

Without being limited thereto, the designer may apply any attachment method that does not significantly reduce the heat transfer efficiency between the cooling plate 202 , the driving motor 100 , and/or the thermoelectric element 201 .

Referring to FIG. 4 , the heat dissipation plate 203 includes a first heat dissipation unit 2031 and a second heat dissipation unit 2032 . In one embodiment, a plurality of second heat dissipation units 2032 are vertically and densely arranged in one first heat dissipation unit 2031 .

Referring to FIG. 4 , the heat dissipation plate 203 includes a first heat dissipation unit 2031 and a second heat dissipation unit 2032 . The first heat dissipation part 2031 includes one surface attached to the other surface of the thermoelectric element 201 and the other surface opposite to the one surface and to which the second heat radiation part 2032 is attached.

The first heat dissipation unit 2031 is attached to the other surface of the thermoelectric element 201 to receive heat from the thermoelectric element 201 , and the second heat dissipation unit 2031 is a plurality of units attached to the other surface of the first heat dissipation unit 2031 . It is composed of fins of For example, the second heat dissipation unit 2031 may be a plurality of fins vertically attached to the first heat dissipation unit 2031 .

Accordingly, the contact area between the second heat dissipation unit 2031 and the air is increased, so that heat generated from the other surface of the thermoelectric element 201 can be effectively transferred to the outside. The heat sink 203 may be made of a material having high thermal conductivity. For example, the heat sink 203 may be made of a thermally conductive ceramic material that smoothly conducts heat while being less affected by corrosion. In one example, the heat sink 203 may be made of the same material as the cooling plate 202 or a different material.

One surface of the first heat dissipation unit 2031 may have a shape corresponding to the other surface of the thermoelectric element 201 . When the thermoelectric element 201 has a rectangular flat plate shape, the first heat dissipation unit 2031 may also have a rectangular flat plate shape. The heat sink 203 may be attached to the thermoelectric element 201 in various ways such as adhesives, screws, welding, pins, and the like. The designer may apply any attachment method that does not significantly reduce the heat transfer efficiency between the heat sink 203 and/or the thermoelectric element 201 .

The cooling fan 204 blows air toward the heat sink 203 to increase the heat dissipation efficiency of the heat sink 203 . Looking at the structure in which the cooling fan 204 is installed inside the juicer 1 , in one example, it is mounted on the lower end of the heat sink 203 to blow the air to the heat sink 203 , in particular, the second heat sink 2032 . In this case, the wind generated by the cooling fan 204 moves upward through the plurality of fins constituting the second heat dissipation unit 2031 , and discharges the heat of the heat dissipation plate 203 to the outside. In another example, the cooling fan 204 may suck the heat generated by the heat sink 203 and discharge it to the outside of the juicer 1 .

The cooling fan 204 may be screwed to the lower end of the heat sink 203 , but the coupling between the cooling fan 204 and the heat sink 203 is not limited thereto. The cooling fan 204 may include a blade 2042 for generating wind and a fan housing 2041 on which the blade 2042 is rotatably mounted and forms an outer shape of the cooling fan 204 .

In the present specification, it is illustrated that the cooling fan 204 is mounted on the lower end of the heat sink 203 , but the position of the cooling fan 204 is not limited thereto. As an example, it can be mounted anywhere, such as at the top of the heat sink 203 or at a place where ventilation is formed in the juicer 1 . As another example, the cooling fan 204 may be located at an arbitrary position capable of blowing air between the plurality of fins constituting the second heat dissipation unit 2032 . For example, the cooling fan 204 may be mounted on the bottom surface of the inner body 11 corresponding to the heat sink 203 .

In addition, the driving motor 100 and the first contact surface 2021, the second contact surface 2022 and the heat absorbing surface of the thermoelectric element 201, the heat dissipation surface of the thermoelectric element 201 and the first heat generating part 2031 are thermally conductive. Thermal grease or thermally conductive silicone may be added to make it smooth.

Hereinafter, a driving process of the cooling module according to an embodiment of the present invention will be described in detail with reference to FIGS. 5 to 6 .

5 is a conceptual diagram of a drive motor for a juicer in which a cooling module is mounted on one side according to an embodiment of the present invention, and FIG. 6 is a drive motor for a juicer in which a cooling module according to an embodiment of the present invention is mounted on both sides. It corresponds to the conceptual diagram.

First, a driving principle of the driving motor 100 and the cooling module 200 will be described. According to an embodiment of the present invention, since the current to the driving motor 100 and the cooling module 200 can be simultaneously applied by the switch 304 , the driving motor 100 is driven and the cooling module 200 . These can be driven together.

Hereinafter, the simultaneous driving of the driving motor 100 and the cooling module 200 will be described in detail through the conceptual diagram. When the circuits of the driving motor 100 and the cooling module 200 will be sequentially described, the juicer 1 includes a current fuse 302 in a portion to which a current is first introduced. The current fuse 302 serves as a safety device to block when an excessive current is applied to the driving motor 100 and the cooling module 200 .

In addition, the juicer (1) further includes a micro switch (303). In the case of the micro switch 303, when the user attaches the cover 60 to the juice drum 20 or separates it from the juice drum 20 to use the juicer 1, it detects this and determines whether to apply a current. It is a safety device. When the cover 60 is mounted on the juice drum 20, the micro switch 303 is turned on and current flows, and when the cover 1 is separated from the juice drum 20, the micro switch 303 is turned off. ) to cut the current.

The juicer 1 further includes a switch 304 . The driving of the driving motor 100 and the cooling module 200 is simultaneously controlled through the switch 304 . When the switch 304 is turned on, current is applied to the driving motor 100 and the power supply device 301 connected to the cooling module 200, respectively.

The power supply 301 is connected to the thermoelectric element 201 and the cooling fan 204 of the cooling module 200 . Accordingly, the current applied to the power supply device 301 is applied separately to the thermoelectric element 201 and the cooling fan 204 .

Accordingly, the thermoelectric element 201 and the cooling fan 204 are simultaneously driven. Therefore, cold air is transferred to the cooling plate 202 through one surface of the thermoelectric element 201 and finally, cold air is transferred to the driving motor 100 through the cooling plate 202, and the driving motor 100 is below a certain temperature. is cooled with

On the other hand, since the other surface of the thermoelectric element 201 generates heat, the heat is radiated through the heat sink 203 , and the radiated heat is transferred away from the heat sink 203 through the cooling fan 204 .

The juicer 1 may further include a temperature sensor (not shown) for measuring the temperature of the driving motor 100 . The temperature sensor is electrically connected to the micro switch 303 , the switch 304 , and/or a separate temperature protection device so that the temperature of the driving motor 100 measured by the temperature sensor controls the operation of the driving motor 100 . can be used to For example, when the temperature of the driving motor 100 rises above a certain level, the micro switch 303 or the switch 304 may be turned off or the temperature protection device may be operated to stop the driving motor 100 .

However, since the cooling module 200 operates together with the driving motor 100 in the juicer 1 according to an embodiment of the present invention, the temperature of the driving motor 100 is prevented from rising above a certain level. Therefore, since the temperature protection device operates and the problem of stopping the juicer 1 does not occur, the user can use a much longer time than the use time of the conventional juicer.

Although it has been exemplified that one cooling module 200 is mounted on the outer circumferential surface of the driving motor 100 , a plurality of cooling modules 200 may be mounted on the driving motor 100 . For example, referring to FIG. 6 , two cooling modules 200 are mounted on the outer peripheral surface of the driving motor 100 according to the heat generation state of the driving motor 100 .

When the cooling module 200 is mounted to surround the outer circumferential surface of the driving motor 100 , heat exchange with the driving motor 100 is performed in a shorter time, and thermal equilibrium can be realized. In one example, the plurality of cooling modules 200 may be mounted to surround the entire outer circumferential surface of the driving motor 100 . Accordingly, cold air may be evenly transmitted to the entire driving motor 100 .

Hereinafter, when the cooling module 200 is mounted through the embodiment of the present invention, the temperature reduction and maintenance of the driving motor 100 will be described.

7A is a graph showing the result of temperature measurement when the driving motor for the juicer equipped with the cooling module is driven according to an embodiment of the present invention, and FIG. 7B is the temperature measurement when the driving motor for the juicer equipped with the cooling module is driven. It corresponds to the graph showing the result.

In each of FIGS. 7A and 7B , the vertical axis represents the temperature of the driving motor 100 (in detail, it represents the temperature of a coil located in the driving motor 100 ), and the horizontal axis represents the operating time. The temperature is in degrees Celsius, and the solid line indicates the average temperature of the driving motor 100 at room temperature.

A plurality of coils are included in the driving motor 100 , and the plurality of coils are classified into a main coil and a sub-coil. A dotted line indicates the temperature of the sub-coil, and a dashed-dotted line indicates the temperature of the main coil. A higher value among the maximum values of the sub-coil temperature and the main coil temperature is recorded as the heating temperature of the driving motor 100 .

The sub-coil temperature and the main coil temperature were measured in minutes, but the temperatures measured in 30-minute units were recorded. When the cooling module 200 is mounted and when the cooling module 200 is not mounted, the temperature was measured while operating for about 3 hours. In detail, when the cooling module was installed, the temperature was measured while the driving motor was operated for 3 hours and 13 minutes, and when the cooling module 200 was not installed, the temperature was measured while the driving motor was operated for 3 hours and 10 minutes.

In the temperature measurement test method, first, a driving motor 100 equipped with a thermoelectric element 201 (specifically, a thermoelectric element 201 including a Peltier semiconductor) is mounted on the bottom plate of the undiluted solution 1 . After that, the drive motor 100 is covered with a paper box (however, at least one ventilation is secured on the upper side of the paper box), and the coil temperature of the drive motor 100 was measured.

As shown in FIG. 7A , in the case of the driving motor 100 equipped with the cooling module 200, the maximum temperature of the driving motor 100 converges to the maximum value of 85.2° C. after about 1 hour and 30 minutes from the start of temperature measurement. and showed a saturation phenomenon.

On the other hand, as shown in FIG. 7B , in the case of a driving motor without a cooling module, the maximum temperature of the driving motor 100 was measured at about 100° C. after about 1 hour and 30 minutes from the start of temperature measurement, but 3 hours and 10 minutes When the temperature was measured after elapsed time, the maximum temperature was measured to be 105.2°C, and it was found that it was gradually increasing.

Through the above experimental results, the driving motor 100 for the juicer equipped with the cooling module 200 according to the present invention increases the rated use time of the home juicer 1 compared to the conventional use time, and preferably 24 hours. It can be confirmed that continuous use is possible.

Since the temperature protection device of the juicer (1) operates and there is no risk of the drive motor 100 stopping, from the user's point of view, the juicer (1) smoothly without an intermediate waiting time during the driving process of the juicer (1) can be used

In addition, the present invention is not limited to home use by strengthening the durability of the reducer gear, and can be used for extended use as a commercial product.

In addition, the present invention can reduce the size, weight and cost of the conventional juicer by applying the cooling module to the existing motor.

Up to now, the driving motor for the undiluted solution equipped with the thermoelectric element cooling module according to the present invention has been described with reference to the embodiment shown in the drawings, but this is only an example, and anyone skilled in the art can make various modifications and equivalent embodiments therefrom. will understand that Therefore, the true scope of technical protection should be determined by the technical idea of the appended claims, and all technical ideas within the equivalent range should be interpreted as being included in the scope of the present invention.
