Description

juicer

[0001] The present invention relates to a juicer, and more specifically, to a juicer comprising a gear assembly for transmitting power to a rotating brush on the lower surface of a juicer drum of the juicer, wherein a main gear is coupled to be supported on one side through a bushing on the lower surface of the juicer drum housing, thereby reducing the operating load, thereby lowering the risk of damage and loss, and making maintenance easy.

[0002] In order to lead a healthy life, the number of people making their own juices at home is increasing, and for this purpose, many devices that allow people to easily make juices using vegetables or fruits at home are being introduced.

[0003] From the above point of view, the prior art 1 (registered patent no. 10-1038074 (June 1, 2011)) has a drive transmission path from the main drive shaft (101) to the first rotation gear (102), the first rotation shaft (103), and the second power transmission gear (110) to rotate the rotation brush part (400).

[0004] However, this prior art 1 has a complicated drive transmission path and is cumbersome in that it requires additional preparation and installation of unnecessary shaft members and gears to transmit the driving force from the motor.

[0005] Therefore, these prior technologies had the problem of increasing the volume and weight of the entire device because they required additional space and area for mounting the increased number of shaft members and gears.

[0006] In addition, prior art 2 (registered patent no. 10-1462650 (2014.11.20.)) discloses a juice extraction module for a juicer that simplifies the drive transmission path, thereby reducing the number of parts and reducing production costs.

[0007] However, this prior art 2 has a problem in that the main gear can be separated and detached downward when the main body and the juice drum are separated, so a separate gear box is additionally provided to support the bottom of the main gear, making the configuration complex and difficult to maintain, and there is a risk of loss because the main gear is separated together when the gear box is opened.

[0008] In addition, since the main gear is not rigidly supported and only makes contact with the gearbox, there was a problem in that the vibration of the screw's rotational force was transmitted to the entire configuration of the drive transmission assembly, resulting in damage due to operating load.

[0009] The purpose of the present invention is to provide a juicer that simplifies the drive transmission path, prevents damage and loss of parts, and facilitates cleaning to maintain cleanliness.

[0010] Another object of the present invention is to provide a driving gear that is stably supported and driven by a juice drum by being coupled with a bushing to prevent loss and is firmly coupled to prevent damage due to operating load.

[0011] According to one aspect of the present invention for achieving the above object, a juicer comprises: a juicer drum including a juicer net that receives a driving force from a driving shaft and receives a rotating screw; a rotating brush disposed on the outside of the juicer net; and a housing that receives the screw, the juicer net, and the rotating brush; a main gear formed to support one side of the lower surface of the housing of the juicer drum and transmits the power of the driving shaft to a driven gear; a bushing portion coupled to an upper portion of the main gear and supporting one side of the main gear to prevent the main gear from being separated to the lower portion of the juicer drum; and a driven gear having a lower portion gear-coupled with the main gear and an upper portion disposed on a bottom surface inside the housing of the juicer drum; the rotating brush is provided with a linkage gear formed along an inner surface of a lower portion, and the linkage gear is gear-coupled with an upper portion of the driven gear and is rotationally driven in conjunction with the driven gear to sweep the outer surface of the juicer net and the inner surface of the juicer drum; The upper part of the driven gear is positioned inside the juice drum, and the lower parts of the main gear and the driven gear are positioned on the bottom surface outside the juice drum.

[0012] In addition, in a juicer according to one aspect of the present invention, the bushing part may be positioned between the juice drum and the main gear so as to support one side of the main gear.

[0013] In addition, in a juicer according to one aspect of the present invention, the main gear is provided with a joint portion protruding upward to which a drive shaft or a screw shaft is coupled, and has a joint groove on the outer circumference of the joint portion; and the bushing portion has a joint projection on the lower portion, so that the joint projection of the bushing portion is coupled to the joint groove of the main gear to prevent the main gear from coming off.

[0014] In addition, in the juicer according to one aspect of the present invention, the bushing part is formed with a bushing mounting part that extends radially at the top; and can be mounted and supported on the upper part of the hollow part of the bottom of the juice drum housing.

[0015] In addition, in a juicer according to one aspect of the present invention, the bushing part is characterized by having at least one cut portion and being elastically deformable to facilitate coupling and separation with the main gear.

[0016] In addition, in a juicer according to one aspect of the present invention, the driven gear may include an upper gear that is gear-engaged with a gear of a rotating brush; a shaft that protrudes from the center of the upper gear and penetrates the bottom surface of the juice drum; and a lower gear that is provided at the lower end of the shaft and is gear-engaged with the main gear.

[0017] In addition, in the juicer according to one aspect of the present invention, a sealing part may be further combined with the lower part of the upper gear of the driven gear to improve the sealing property of the housing of the juice drum.

[0018] According to the present invention, the drive transmission path is simplified, the risk of damage and loss of parts is prevented, and cleaning is facilitated, thereby maintaining cleanliness.

[0019] In addition, according to the present invention, the main gear is stably supported and driven by the juice drum by being combined with the bushing portion, thereby preventing loss, and is firmly combined to prevent damage due to operating load.
