Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so as to be easily implemented by those skilled in the art. However, in describing the preferred embodiment of the present invention in detail, if a detailed description of related known functions or configurations is deemed to make the gist of the present invention unclear, the detailed description thereof will be omitted. Further, in all the drawings, the same reference numerals are used for portions having similar functions and actions. In the present specification, terms such as "upper", "lower", "side", and the like are based on the drawings, and may actually vary depending on the arrangement direction of elements or components.
In addition, when a certain component is described as being 'connected' to other components throughout the specification, not only the case of 'directly connecting' but also the case of 'indirectly connecting' through other elements interposed therebetween is included. Furthermore, unless explicitly stated to the contrary, the term 'comprising' should be understood to include other elements as well, but not to exclude other elements.
Fig. 1 is a view showing a blender equipped with a driving apparatus according to the present invention, and fig. 2 and 3 are views showing a structure after a cover unit is removed inside the blender of fig. 1.
Referring to the drawings, the blender includes a blender body 100 and a cover unit 200.
The blender body 100 may include a crushing blade 110 and a blade driving part 120 for driving the crushing blade 110 to rotate.
Specifically, the crushing blade 110 is provided inside the rotary drum 130, and performs a crushing function on the agitation target object inside the rotary drum 130 while rotating. In this case, the object to be kneaded is food that can be pulverized by the operation of the mixer.
Meanwhile, the blade driving part 120 may have a blade rotating shaft 122 and a blade driving motor 121 as a structure for providing a driving force for rotating the pulverizing blade 110.
At this time, the blade rotating shaft 122 has a structure connected to a lower portion of the crushing blade 110.
Such a blade rotating shaft 122 connects the crushing blade 110 with the blade driving motor 121, and by transmitting the rotational driving force of the blade driving motor 121 to the crushing blade 110, the crushing blade 110 can be rotationally driven when the blade driving motor 121 is operated.
At this time, the blade rotation shaft 122 and the blade driving motor 121 may be connected through a blade driving connection line 123 such as a timing belt.
In addition, the mixer body 100 may include a rotary drum 130 and a drum driving part 140.
The crushing blade 110 is provided inside the rotary drum 130, and the upper portion of the rotary drum 130 has an upper opening structure with an open upper portion and is configured to be opened or closed by an outer drum cover 150.
In addition, a protrusion 131 is formed on an inner side surface of the rotary cylinder 130 to block the object to be stirred, which is pulverized and rotationally flowed by the pulverizing blade 110.
Meanwhile, the drum driving part 140 may have a drum driving motor 141 and a drum rotating shaft 142 as a structure for providing a driving force for rotating the rotary drum 130.
The drum rotating shaft 142 has a structure connected to a lower portion of the rotary drum 130.
Such a drum rotating shaft 142 may rotatably drive the rotary drum 130 when the drum driving motor 141 is operated by connecting the rotary drum 130 with the drum driving motor 141 such that the rotational driving force of the drum driving motor 141 is transmitted to the rotary drum 130.
At this time, the drum driving motor 141 and the drum rotation shaft 142 may be connected through a drum driving connection line 143 such as a timing belt.
On the other hand, the blade driving part 120 and the cartridge driving part 140 as described above may be controlled by a controller (not shown), and particularly, the blade driving motor 121 of the blade driving part 120 and the cartridge driving motor 141 of the cartridge driving part 140 may be electrically connected with the controller, so that the blade driving motor 121 and the cartridge driving motor 141 may be controlled by the controller.
In the conventional agitator, since the crushing blade 110 is rotated in only one direction, and the object to be agitated is continuously rotated in only one direction in the agitating drum, the object to be agitated is kept as if it were a wall in a state of being pushed in a direction toward the inner side of the agitator housing, and cannot be returned to the crushing blade 110, so that the crushing performance is remarkably lowered.
Of course, the conventional mixer has a limitation that the object to be mixed cannot be sufficiently pulverized because the object to be mixed is made to flow in a regular pattern by forming the protrusions on the inner wall of the mixing drum so that the object to be mixed generates a certain degree of vortex.
Thus, in order to achieve an irregular flow of the object to be stirred, that is, to break the equilibrium state of the object to be stirred inside the rotary drum 130, the mixer according to the present invention may control the drum driving part 140 by the controller so as to repeat a mode in which the rotary drum 130 is reversed in a direction opposite to the crushing blade 110 and then stopped or a mode in which the speed is changed after the reversal.
As described above, the mixer according to the present invention can break the equilibrium state of the mixing target object by controlling the drum driving part 140 by the controller, so that the mixing target object is not accumulated as if it were a wall shape on the inner side surface of the rotary drum 130, but can be returned to the crushing blade 110 rotating at the center part of the rotary drum 130 again, thereby remarkably improving the crushing performance.
That is, the mixer according to the present invention is configured to break the balance of the object to be mixed, and break the object to be mixed which is maintained in a wall-like shape on the inner side surface of the rotary cylinder 130, thereby eventually improving the pulverizing performance for the object to be mixed.
Specifically, the object to be stirred moves toward the inner side surface of the rotary drum 130 by the centrifugal force caused by the rotation of the crushing blade 110 while being stirred, and at this time, if the force is balanced (balanced) between the particles of the object to be stirred, the object to be stirred stops without moving again, and cannot move toward the crushing blade 110, and thus cannot be further crushed.
However, with regard to the above-described balance of the forces among the particles of the object to be stirred, it is possible to break the balance by repeating the mode in which the rotary cylinder 130 is stopped after the reversal or the mode in which the rotation speed is changed after the reversal in the stirrer according to the present invention, cause the particles to flow again, and continue the pulverization of the object to be stirred toward the pulverizing blade 110 side during the flow.
Fig. 4 is a view showing that the blade driving motor of fig. 2 is covered with a cover unit of a driving apparatus according to the present invention, fig. 5 is an exploded perspective view showing that the cover unit of fig. 4 is separated from a base plate, and fig. 6 is a longitudinal sectional view showing the inside of a main body case of fig. 4.
Referring to the drawings, the cover unit 200 of the present invention is mounted on the blender body 100 for covering the blade driving motor 121 in multiple.
Such a cover unit 200 has an effect of preventing the operating noise of the blade driving motor 121 from being transmitted to the outside.
Specifically, the cover unit 200 includes an inner cover 210 and an outer cover 220.
The inner cover 210 covers the blade driving motor 121.
Further, the outer cap 220 covers the inner cap 210 outside the inner cap 210, and in the drawing, the inner cap 210 is covered with one outer cap 220, however, the present invention is not limited thereto, and at least one outer cap 220 may be provided to cover the inner cap 210 in multiple.
As described above, the present invention includes the inner lid 210 and the at least one outer lid 220, and by covering the blade driving motor 121 with the lid structure provided in at least two layers, it is possible to prevent noise of the motor generated from the blade driving motor 121 from being transmitted to the outside, so that it is possible to remarkably reduce the magnitude of the operation noise of the blender.
Further, since the present invention has such a cover unit 200, even in the case where the blade driving motor 121 is covered, it is possible to minimize heat generated during the operation of the blade driving motor 121.
That is, the present invention has the cooling fan 121a disposed at the upper portion of the blade driving motor 121, and the blade driving motor 121 is cooled by the operation of the cooling fan 121a, and in order to improve the cooling efficiency of the cooling fan 121a, an exhaust passage may be formed to smoothly discharge the air escaped from the inner cover 210.
Specifically, in the present invention, the cooling fan 121a disposed at the upper portion of the blade driving motor 121 is configured to blow air toward the blade driving motor 121 side, and at the same time, the exhaust passage, which is a path for exhausting air from the inside of the inner cover 210 toward the outside of the blender, may be formed in a straight line shape instead of a curved shape.
As described above, by forming the air discharge passage in a linear shape instead of a curved shape, it is possible to prevent the air escaping from the inside of the inner lid 210 from being deflected during air discharge to cause unsmooth air discharge.
In other words, in the present invention, by forming the air discharge passage in a linear shape instead of a curved shape, the air escaping from the inside of the inner lid 210 can be quickly discharged from the inner lid 210 to the outside without changing direction.
More specifically, the present invention may employ the following structure to make the exhaust passage have a straight line shape rather than a curved shape.
The blade driving motor 121, the inner lid 210, and the outer lid 220 are mounted on the upper portion of the bottom plate 190 inside the body case 180 of the mixer body 100.
Wherein the inner cover 210 and the outer cover 220 adopt a structure in which the lower portion is opened so as to cover the blade driving motor 121 while descending from the upper side of the blade driving motor 121 to the blade driving motor 121 side.
At this time, the base discharge hole 190b is formed at a portion of the bottom plate 190 at a lower side of the blade driving motor 121, and the housing discharge hole 180b is formed at a portion of the main body housing 180 at a lower side of the base discharge hole 190 b.
Thus, the air discharge passage may be formed as a path through which air flows from the inside of the inner cover 210 through the base discharge hole 190b and the housing discharge hole 180b in order.
That is, the air blown from the cooling fan 121a cools the blade driving motor 121 while flowing downward, and then flows through the bottom discharge hole 190b and the housing discharge hole 180b in order and is discharged to the outside of the blender.
Thus, the cooling fan 121a, the blade driving motor 121, the base discharge hole 190b, and the housing discharge hole 180b are sequentially disposed downward, so that a structure formed toward the lower side in the longitudinal direction of the exhaust passage may be constructed.
As described above, in the present invention, the exhaust passage is configured in a linear shape instead of a curved shape, and specifically, by adopting a structure formed toward the longitudinal lower side, the air discharged from the inside of the inner cover 210 is quickly discharged to the outside of the inner cover 210 without changing the direction, whereby the air is smoothly discharged, so that the cooling efficiency of the blade driving motor 121 can be improved.
Further, when air is blown from the cooling fan 121a toward the blade driving motor 121 on the lower side, covering the inner side surface of the inner cover 210 of the blade driving motor 121 around the blade driving motor 121 may prevent the air from being diffused, and since the blade driving motor 121 may be intensively cooled, the cooling efficiency of the blade driving motor 121 may be further improved.
On the other hand, in the present invention, the air supply passage may be a path for supplying air from the outside of the blender to the inside of the inner lid 210, and may have a structure passing through the space between the outer lid 220 and the inner lid 210 and connected to the inside of the inner lid 210 through the upper portion of the inner lid 210.
Specifically, in the present invention, a housing supply hole 180a is formed at a lower end of a side portion of the body housing 180, a bottom supply hole 190a is formed at a portion of the lower bottom plate 190 between the outer cap 220 and the inner cap 210, and a cap supply hole 210a is formed at an upper portion of the inner cap 210.
Thus, the air supply passage may be formed by passing through the bottom supply hole 190a and the cover supply hole 210a in order from the case supply hole 180 a.
That is, air flowing in from the outside of the blender through the case supply hole 180a may flow in between the outer lid 220 and the inner lid 210 through the bottom supply hole 190a, and after moving to the upper side of the inner lid 210, may be supplied to the inner lid 210 through the lid supply hole 210 a.
As described above, the air supply passage may be formed in a curved rather than linear shape by adopting a structure that ascends along between the outer cover 220 and the inner cover 210 and descends through the cover supply hole 210a formed at the upper portion of the inner cover 210, and thus, the direction of air may be changed and supplied to the inner cover 210, and nevertheless, as described later, the air may be rapidly supplied to the inside of the inner cover 210.
Because the influence of the structure of the exhaust channel on the air flow is relatively large when comparing the air flow of the supply channel with the air flow of the exhaust channel.
Specifically, if the air is smoothly discharged, a large negative pressure is formed in the inner space of the inner lid 210, so that the air can be smoothly supplied.
On the contrary, if the air is not smoothly discharged, since a sufficient negative pressure is not formed in the inner space of the inner lid 210, the air cannot be smoothly supplied.
For example, in the present invention, when the air supply passage and the air discharge passage are exchanged, that is, when the arrows of the flow direction shown in the drawings are formed in the opposite direction, the air cannot be smoothly supplied.
That is, even if the air supply passage is formed in a straight line shape, when the air discharge passage is formed in a curved non-straight line shape, air cannot be smoothly supplied through the air supply passage.
Specifically, when air is discharged through the curved non-linear exhaust passage, the air collides with the inner wall of the turning portion of the exhaust passage, so the exhaust speed is significantly reduced, and the air cannot be smoothly discharged due to the generation of a vortex at the turning portion.
On the other hand, in the present invention, the air guide 211 may be formed at the inner cover 210.
The air guide portion 211 has a function of allowing air supplied to the inside of the inner cover 210 through the cover supply hole 210a to flow into the inside of the inner cover 210 in the rotation direction of the cooling fan 121 a.
Specifically, a portion of the edge of the cover supply hole 210a located in the rotation direction of the cooling fan 121a protrudes along the upper side and extends in the direction opposite to the rotation direction of the cooling fan 121a to form the air guide 211.
Accordingly, the cover supply hole 210a has a structure in which the inflow port for inflow of air is arranged in a lateral direction on the upper surface of the inner cover 210, and is gradually moved inward from the inflow port due to the shape of the air guide portion 211 as described above, and then is changed to an upright structure, and at the same time, since the inflow port has a structure facing a direction opposite to the rotation direction of the cooling fan 121a, the air supplied to the inside of the inner cover 210 through the cover supply hole 210a flows into the inside of the inner cover 210 in the rotation direction of the cooling fan 121 a.
As described above, the air guide portion 211 causes the air supplied to the inside of the inner cover 210 through the cover supply hole 210a to flow into the inside of the inner cover 210 through the cover supply hole 210a in the rotation direction of the cooling fan 121a, whereby the air is more smoothly supplied to the inside of the inner cover 210, so that the cooling efficiency of the blade driving motor 121 can be further improved.
In conclusion, the driving apparatus of the blender according to the present invention has the cover unit 200 that covers the blade driving motor 121 in multiple times to prevent the operation noise of the blade driving motor 121 from being transmitted to the outside, and can remarkably reduce the magnitude of the operation noise of the blender by preventing the noise of the motor generated by the blade driving motor 121 from being transmitted to the outside of the blender.
Also, in the present invention, the air discharge path is constructed in a linear shape instead of a curved shape, and more particularly, by adopting a structure formed toward the lower side in the longitudinal direction, the air discharged from the inside of the inner cover 210 is quickly discharged to the outside of the inner cover 210 without changing the direction, whereby the air is smoothly discharged, so that the cooling efficiency of the blade driving motor 121 can be improved.
Meanwhile, in the present invention, when air is blown from the cooling fan 121a to the blade driving motor 121 on the lower side, the inner side of the inner cover 210 covering the blade driving motor 121 around the blade driving motor 121 may prevent the air from being diffused, and since the blade driving motor 121 is intensively cooled, the cooling efficiency of the blade driving motor 121 may be further improved.
Further, in the present invention, the air guide portion 211 is formed at the upper portion of the inner cover 210, and thus the air supplied to the inside of the inner cover 210 through the cover supply hole 210a may flow into the inside of the inner cover 210 through the cover supply hole 210a in the rotation direction of the cooling fan 121a, whereby the air is more smoothly supplied to the inside of the inner cover 210, and thus the cooling efficiency of the blade driving motor 121 can be further improved.
The embodiments of the present invention have been described above with reference to the accompanying drawings, but those having ordinary knowledge in the field of the present invention will understand that the present invention can be embodied in other specific forms without changing its technical idea or essential features. The embodiments described above are therefore to be considered in all respects as illustrative and not restrictive.
