Description

mixer drive unit

[0001] The present invention relates to a driving device for a mixer.

[0002] In general, a mixer is an electric device consisting of a container (cup) for putting the mixing object in and a body with an electric motor housed inside.

[0003] Here, the container is made of hard heat-resistant glass, synthetic resin or stainless steel, and a stainless steel crushing blade is mounted on the lower part of the container and engages with the driving part.

[0004] These crushing blades have been widely used at home for cutting and crushing objects to be mixed, including fruits and vegetables, as well as for extracting juice from objects to be mixed, as they rotate at high speeds.

[0005] However, the mixer has a limitation in that the overall size of the mixer is quite large because the blade drive motor that rotates the grinding blade is arranged longitudinally.

[0006] The present invention was created to solve the above problems, and its purpose is to provide a drive device for a mixer that can reduce the overall size of the mixer.

[0007] In order to achieve the above purpose, a drive device of a mixer according to one embodiment of the present invention includes: a blade rotation shaft connected to a grinding blade and arranged in a longitudinal direction; a blade drive motor arranged transversely in a state perpendicular to the blade rotation shaft; and a blade drive connection connecting the blade rotation shaft and the blade drive motor.

[0008] The above blade drive connection part includes a blade drive belt that winds and connects the motor shaft of the blade drive motor and the blade rotation shaft to transmit the rotational driving force of the blade drive motor to the blade rotation shaft; and a roller unit that supports the blade drive belt; and the blade drive belt can be arranged to be bent while passing through the roller unit.

[0009] The roller unit includes a first roller and a second roller arranged spaced apart from each other, and the first roller can support a portion of the blade drive belt that moves from the motor shaft to the blade rotation axis, and the second roller can support a portion of the blade drive belt that moves from the blade rotation axis to the motor shaft.

[0010] The blade drive belt may be arranged to be twisted in each of a section from the motor shaft to the first roller, a section from the first roller to the blade rotation axis, a section from the blade rotation axis to the second roller, and a section from the second roller to the motor shaft, wherein one of the two surfaces is in contact with the motor shaft, the first roller, the blade rotation axis, and the second roller.

[0011] The blade rotation shaft, the blade drive motor, and the roller unit are installed in a horizontal bulkhead arranged transversely inside the mixer, and the blade rotation shaft and the roller unit are arranged on the upper part of the horizontal bulkhead, the blade drive motor is arranged on the lower part, and a through hole through which the blade drive belt passes may be formed in a portion of the horizontal bulkhead between the roller unit and the motor shaft.

[0012] The above blade drive belt may be a timing belt with a built-in iron core.

[0013] The present invention is configured with a structure in which the blade driving motor is arranged in a horizontal direction, so that the volume of the mixer product is reduced, thereby reducing the constraints on the installation space of the mixer, and the aesthetic appeal is also improved, and the product cost can be reduced.

[0014] Furthermore, the present invention can stably and smoothly transmit rotational driving force from a blade drive motor arranged transversely to a blade rotation shaft arranged longitudinally by having a blade drive belt arranged in a banded manner and having a twisted structure.

[0021] Hereinafter, with reference to the attached drawings, preferred embodiments will be described in detail so that those skilled in the art can easily practice the present invention. However, in describing preferred embodiments of the present invention in detail, if it is determined that a specific description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, the same reference numerals are used throughout the drawings for parts that have similar functions and actions. In addition, in this specification, terms such as “upper,” “upper part,” “top surface,” “lower,” “lower side,” “lower surface,” and “side” are based on the drawings, and in reality, they may vary depending on the direction in which the components are arranged.

[0022] Additionally, throughout the specification, when a part is said to be "connected" to another part, this includes not only cases where it is "directly connected," but also cases where it is "indirectly connected" with other components intervening. Furthermore, unless specifically stated otherwise, "including" a component does not exclude other components, but rather implies the inclusion of other components.

[0023]

[0024] FIG. 1 is a drawing showing a mixer having a drive device installed according to one embodiment of the present invention, FIG. 2 is a drawing showing the lower part of the mixer of FIG. 1 open, and FIG. 3 is a longitudinal cross-sectional view showing the mixer of FIG. 1.

[0025] FIG. 4 and FIG. 5 are drawings showing the driving device of the mixer of FIG. 2 and FIG. 3, FIG. 6 is a bottom view showing the driving device of FIG. 4, and FIG. 7 is a plan view showing the driving device of FIG. 4.

[0026] Referring to the drawing, a driving device (500) according to one embodiment of the present invention rotates a grinding blade (400) in a mixer.

[0027] Let's take a closer look at these mixers:

[0028] The above mixer may include a support case (100), a mixer container (200), a grinding blade (400), and a driving device (500).

[0029] First, the support case (100) is a case that supports the mixer container (200).

[0030] A mounting portion (110) is formed on the upper part of the support case (100) to which the mixer container (200) is mounted. The mounting portion (110) has a groove-shaped structure into which the lower part of the mixer container (200) is inserted and assembled.

[0031] A driving device (500) that rotates and drives the grinding blade (400) of the mixer container (200) may be installed inside the support case (100). The driving device (500) may be installed in a horizontal bulkhead (120) provided inside the support case (100).

[0032] A control panel for controlling the driving device (500) and a display unit for displaying the operating status of the driving device (500) may be formed on the outside of the support case (100).

[0033]

[0034] In addition, the mixer container (200) is a container-shaped member that accommodates a mixing object. The mixing object refers to food to be ground by the operation of the mixer.

[0035] The mixer container (200) may include, for example, an outer container (210) and an inner container (220). Of course, as another example, the mixer container (200) may also have a single container structure, although not shown in the drawing.

[0036] The outer tube (210) has an inner tube (220) arranged inside and has an open upper structure, and is configured to be opened and closed by an outer tube cover (211). If the inner tube (220) has a mesh structure, a discharge pipe (212) may be formed in the outer tube (210) so that the juice of food passing through the inner tube (220) is discharged to the outside.

[0037] The inner tube (220) is arranged within the outer tube (210) and has an open upper structure, and is configured to be opened and closed by the inner tube cover (221). The inner tube (220) may be provided with a crushing blade (400) on the inside. The inner tube (220) may have a protrusion (220a) formed on the inner side. The protrusion (220a) is a part where a mixing object that rotates while being crushed by the crushing blade (400) is caught. The protrusion (220a) may take the shape of an inclined line or a screw line that induces downward spiral flow of the mixing object so that the mixing object flows downward while rotating in the opposite direction to the rotation of the crushing blade (400).

[0038] Furthermore, the inner tube (220) can be configured to rotate by the tube drive device (300).

[0039] The drive device (300) may include a drive shaft (310) and a drive motor (320).

[0040] The rotary shaft (310) is connected to the lower part of the inner tube (220) and can be arranged in the longitudinal direction.

[0041] The drive motor (320) is connected to the drive shaft (310) and the drive belt (330) and provides a rotational driving force to rotate the inner cylinder (220). That is, the drive shaft (310) is configured to connect the inner cylinder (220) and the drive motor (320) and transmit the rotational driving force of the drive motor (320) to the inner cylinder (220), so that when the drive motor (320) is operated, the inner cylinder (220) is rotationally driven.

[0042]

[0043] And the crushing blade (400) is placed inside the inner tube (220) and performs the function of crushing the mixing target inside the inner tube (220) when rotating.

[0044] Meanwhile, the driving device (500) is a blade driving device configured to rotate the crushing blade (400), and its specific structure is described below.

[0045] The above driving device (500) may include a blade rotation shaft (510), a blade driving motor (520), and a blade driving connection (530).

[0046] The blade rotation axis (510) is connected to the crushing blade (400) and can be arranged longitudinally.

[0047] Additionally, the blade drive motor (520) can be positioned transversely in a state perpendicular to the blade rotation axis (510).

[0048] The drive device of a mixer according to the prior art has a blade drive motor that rotates the grinding blade in the longitudinal direction, which has the disadvantage of increasing the overall size of the mixer.

[0049] As a specific example, if a blade drive motor arranged longitudinally is installed on one side of the mixer container, the transverse circumference of the mixer becomes significantly longer. As another example, if a blade drive motor arranged longitudinally is installed on the lower side of the mixer container, the longitudinal length of the mixer becomes significantly longer.

[0050] As described above, if the blade drive motor is positioned longitudinally within the mixer, the mixer's increased volume will lead to limitations in installation space. Furthermore, the aesthetic appeal of the product is compromised, and the product cost increases.

[0051] To overcome these limitations, the drive device (500) of the mixer according to the present invention has a structure in which the blade drive motor (520) is arranged transversely in a state perpendicular to the blade rotation axis (510).

[0052] That is, since the drive device (500) according to the present invention has a structure in which the blade drive motor (520) is arranged horizontally, the volume of the mixer product is reduced, thereby reducing the constraints on the installation space of the mixer, and the aesthetic appeal is also excellent, and the product cost can be reduced.

[0053]

[0054] And the blade drive connection part (530) connects the blade rotation shaft (510) and the blade drive motor (520).

[0055] Specifically, the blade drive connection (530) may include a blade drive belt (531) and a roller unit (532).

[0056] The blade drive belt (531) is wound around and connects the motor shaft (521) of the blade drive motor (520) and the blade rotation shaft (510). This blade drive belt (531) serves to transmit the rotational driving force of the blade drive motor (520) to the blade rotation shaft (510). As an example, the blade drive belt (531) may be a timing belt to ensure transmission of the rotational driving force, and may have an iron core built in to reinforce durability.

[0057] The roller unit (532) has a structure that supports the blade drive belt (531).

[0058] Such roller unit (532) may include a first roller (532a) and a second roller (532b) that are spaced apart from each other.

[0059] The first roller (532a) can support a portion of the blade drive belt (531) that moves from the motor shaft (521) to the blade rotation shaft (510).

[0060] The second roller (532b) can support a portion of the blade drive belt (531) that moves from the blade rotation shaft (510) to the motor shaft (521).

[0061] Due to this, when the blade drive motor (520) operates, the blade drive belt (531) sequentially moves through the motor shaft (521), the first roller (532a), the blade rotation shaft (510), and the second roller (532b) and then rotates back to the motor shaft (521).

[0062] The blade drive belt (531) can be arranged to be banded while passing through the roller unit (532).

[0063] That is, the blade drive belt (531) may bend and change its direction of movement when it passes over the first roller (532a) while moving, and may also bend and change its direction of movement when it passes over the second roller (532b).

[0064] In other words, as shown in the drawing, the blade drive belt (531) moves longitudinally from the motor shaft (521) to the first roller (532a) and then moves transversely from the first roller (532a) to the blade rotation axis (510). In addition, the blade drive belt (531) can move longitudinally from the blade rotation axis (510) to the second roller (532b) and then move transversely from the second roller (532b) to the motor shaft (521).

[0065] Here, the blade drive belt (531) can have one of its two sides in contact with the motor shaft (521), the first roller (532a), the blade rotation shaft (510), and the second roller (532b).

[0066] The blade drive belt (531) is arranged to be bent when passing through each of the first roller (532a) and the second roller (532b). At this time, when one of the two sides of the blade drive belt (531) comes into contact with the motor shaft (521), the first roller (532a), the blade rotation axis (510), and the second roller (532b), the blade drive belt (531) may be arranged to be twisted.

[0067] Specifically, as shown in the drawing, the blade drive belt (531) may be arranged to be twisted in each of the sections from the motor shaft (521) to the first roller (532a), the sections from the first roller (532a) to the blade rotation axis (510), the sections from the blade rotation axis (510) to the second roller (532b), and the sections from the second roller (532b) to the motor shaft (521).

[0068] As described above, the blade drive belt (531) can be arranged in a twisted manner so that one of the two sides is in contact with the motor shaft (521), the first roller (532a), the blade rotation axis (510), and the second roller (532b). Accordingly, the blade drive belt (531) can stably and smoothly transmit the rotational driving force of the horizontally arranged blade drive motor (520) to the vertically arranged blade rotation axis (510).

[0069] In a structure where the motor shaft (521) and the blade rotation axis (510) are perpendicular to each other, if a gear member such as a bevel gear is used instead of the blade drive belt (531) for transmitting the rotational driving force, unlike the present invention, the gear member cannot withstand the rotational driving force of the motor shaft (521) rotating at high speed. Furthermore, as the rotational driving force that the gear member can withstand is large, there is a significant limitation in that the noise from the gear member is also large.

[0070]

[0071] Meanwhile, the blade rotation shaft (510), the blade driving motor (520), and the roller unit (532) can be installed on a horizontal bulkhead (120) arranged transversely inside the mixer.

[0072] A blade rotation shaft (510) and a roller unit (532) may be placed on the upper part of the horizontal bulkhead (120), and a blade driving motor (520) may be placed on the lower part.

[0073] Additionally, a passage hole (120a) through which a blade drive belt (531) passes may be formed between the roller unit (532) and the motor shaft (521) in the horizontal bulkhead (120).

[0074] Due to the structure described above, the blade drive motor (520) can have a stable and sturdy transverse arrangement structure, and the blade drive belt (531) can smoothly transmit the rotational driving force of the blade drive motor (520).

[0075]

[0076] In summary, the present invention is configured with a structure in which the blade drive motor (520) is arranged in a horizontal direction, so that the volume of the mixer product is reduced, thereby reducing the constraints on the installation space of the mixer, and the aesthetic appeal is also improved, and the product cost can be reduced.

[0077] Furthermore, the present invention can stably and smoothly transmit rotational driving force from a blade drive motor (520) arranged in a transverse direction to a blade rotation shaft (510) arranged in a longitudinal direction by having a blade drive belt (531) arranged in a banded manner and having a twisted structure.

[0078]

[0079] Although the embodiments of the present invention have been described with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical spirit or essential characteristics thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
