Description

Technical Field

[0001] The present disclosure relates to a juicer, and more particularly to a juicer capable of expanding an accommodation space for food materials. Background Art

[0002] When using a conventional hopper-type juicer, a user needs to prepare food materials by cutting them into sizes that can be inserted into the inlet of the hopper. However, the accommodation space formed inside the hopper has a limited size. When putting food materials into the hopper, there may be a situation where additional food materials cannot be added to the limited accommodation space of the hopper depending on their cutting shape or cutting size. That is, even when there is space in the accommodation space of the hopper, there may be a situation where more food materials cannot be added.

[0003] In addition, in a case where the amount of prepared food materials is excessive compared to the size of the accommodation space of the hopper and the food materials cannot be put into the hopper at once, it is necessary to additionally add the remaining food materials after the processing of the first-added food materials is gradually completed. When adding additional food materials, for the safety of the user, the juicer of the hopper usually stops operating. In this case, it is troublesome to frequently check the completion state of the juice of the first-added food materials and operate the juicer of the hopper again. Summary of the Invention

[0039] With reference to the embodiments described in detail below in conjunction with the accompanying drawings, the advantages and features of the present invention and the methods for achieving these advantages and features will become apparent. However, the present invention is not limited to the embodiments disclosed below and can be implemented in various different forms. The present embodiment is provided to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the present invention, and the present invention is only defined by the scope of the claims.

[0040] In addition, the embodiments described in this specification will be described with reference to cross-sectional views and / or schematic diagrams that are ideal example diagrams of the present invention. Therefore, the form of the example diagrams can be modified according to manufacturing techniques and / or tolerances, etc. In addition, in each of the drawings shown in the present invention, for convenience of description, the corresponding elements may be shown slightly enlarged or reduced. Throughout the specification, the same reference numerals refer to the same elements. The description of the present invention omits the description of the general functions and structures of the juice extractor 10 and only describes the content related to the present invention.

[0041] Hereinafter, the present invention will be described with reference to the drawings for illustrating a juice extractor according to a first embodiment of the present disclosure.

[0042] Figure 1 It is a perspective view of a juice extractor according to a first embodiment of the present disclosure, Figure 2 is Figure 1 a perspective view of the juice extractor except for the main body, Figure 3 is Figure 1 a perspective view of the main container of the juice extractor, Figure 4 is Figure 1 a perspective view of the extension container of the juice extractor, and Figure 5 is Figure 2 a cross-sectional view taken along line V-V of the juice extractor.

[0043] With reference to Figures 1 to 5 , the juice extractor 10 according to the first embodiment of the present disclosure is configured to expand the accommodation space 110 for food materials and includes a main container 100, a container lid 200, a main body 300, and an extension container 400.

[0044] The main container 100 has a space for accommodating food materials, and the food materials are processed in the accommodation space 110. The main container 100 may include a main container body 130 and a main container coupling portion 140. The main container body 130 forms the accommodation space 110 and may be installed with processing members P for processing food materials, such as container blades, cutting knives, etc.

[0045] The main container body 130 can be formed in a cylindrical shape, where the upper and lower parts of the main container body 130 are open to form an accommodation space. The main container body 130 can be formed in various shapes, such as a cylindrical body or a square cylindrical body with the upper and lower parts of the main container body open.

[0046] An input hole 170 having a space connected to the juice extraction part 600 of the main body 300 (see Figure 17 ) can be formed in the lower part of the main container body 130 which will be described later. The input hole 170 is a passage through which food materials cut into appropriate sizes for juice extraction by the processing member P are put into the juice extraction part 600 from the accommodation space 110.

[0047] An extension container 400 or a container lid 200 can be installed on the upper part of the main container body 130. A main container coupling part 140 can be formed on one side of the main container body 130, and a main container handle 150 can be formed on the other side.

[0048] Figure 7 is a perspective view showing the first safety sensor part of the main container and the second safety sensor part of the extension container, and Figure 2 and Figure 8 is Figure 5 an enlarged view of region VIII of

[0049] Referring to Figure 7 and Figure 8 , the main container body 130 can include a first safety sensor part 131. The first safety sensor part 131 detects whether the container lid 200 is open, and when the expansion space 410 of the main container body 130 is closed or opened by the container lid 200, the first safety sensor part 131 can detect its closed state and open state.

[0050] The first safety sensor part 131 can be formed in the main container body 130. The formation position of the first safety sensor part 131 is not restricted, but preferably the first safety sensor part 131 is formed at a position adjacent to the container lid 200 to accurately detect whether the container lid 200 is open. In the drawings, the first safety sensor part 131 is illustrated as being formed at a position adjacent to the main container coupling part 140, but the first safety sensor part 131 can be formed at a position adjacent to the main container handle 150 or at a position adjacent to the upper edge of the main container body 130.

[0051] When the first safety sensor part 131 detects an open state, for the safety of the user, the operation of the processing member P for processing food materials can be stopped. When the first safety sensor part 131 detects a closed state, the processing member P can continue to operate. The first safety sensor part 131 can be formed in various forms such as contact type, non-contact type, pressure type, etc. For example, when the first safety sensor part 131 is of the contact type, the first safety sensor part 131 can contact a sensor operation part (not shown in the drawings) of the container lid 200 in a closed or open state, which will be described later. The first safety sensor part 131 can contact the sensor operation part in a closed state or can contact the sensor operation part in an open state.

[0052] The first safety sensor part 131 can be connected to a second safety sensor part 421 extending from the container body 420, which will be described later. That is, in the case where the extension container 400 is installed on the main container 100, when the second safety sensor part 421 of the extension container body 420 detects the open or closed state of the extension container 400, the second safety sensor part 421 can also detect the open or closed state. For example, when the first safety sensor part 131 is of the contact type, a signal transmission member 132 can be provided between the second safety sensor part 421 and the first safety sensor part 131, and the signal transmission member 132 transmits the contact of the second safety sensor part 421. The signal transmission member 132 can be configured to transmit an electrical signal such as an electric current or transmit a physical signal such as an external force or pressure. Ultimately, the main body 300 can stop the operation of the processing member P based on the detection of at least one of the first safety sensor part 131 and the second safety sensor part 421.

[0053] However, there is a case where the second safety sensor part 421 cannot detect whether the container lid 200 is open due to its failure or damage. To cope with this situation, the signal transmission member 132 can be provided near the container lid 200. For example, when the first safety sensor part 131 is of the contact type, the signal transmission member 132 is provided at a position adjacent to the upper part of the extension container 400 and can contact the container lid 200. The physical contact between the container lid 200 and the signal transmission member 132 is transmitted to the first safety sensor part 131, and the first safety sensor part 131 can detect whether the container lid 200 is open. Even in the case where the second safety sensor part 421 is not provided in the extension container 400, the signal transmission member 132 can allow the first safety sensor part 131 to detect whether the container lid 200 is open.

[0054] Return to reference Figures 1 to 5, the main container handle 150 is the part held by the user, enabling the user to easily carry the main container 100. The main container handle 150, which will be described later, can be coupled to the extension container handle 450. That is, when the upper part of the main container handle is inserted and coupled to the insertion groove 451 of the main container handle 150, the mounted state of the extension container 400 can be stably maintained. The locking projection 160 (see Figure 10 ) can be formed on the outer surface of the main container handle 150. The locking projection 160 can be caught and coupled to the locking hook 240 (see Figure 10 ) of the container lid handle 230, which will be described later. The coupling of the locking projection 160 and the locking hook 240 can enhance the binding between the main container 100 and the container lid 200.

[0055] Figure 6 is a cross-sectional view taken along the line VI-VI of Figure 2 .

[0056] Referring to Figure 6 , in order to more stably maintain the mounted state of the extension container, a locking claw 151 can be formed on the main container handle 150, and a hook portion 452 including a hook projection 452a can be formed on the extension container handle, which will be described later. The hook projection 452a can be caught on the locking claw 151. The hook projection 452a and the locking claw 151 will be described later.

[0057] The main container coupling portion 140 is the portion that is caught and coupled to the lower extension container coupling portion 430 and the container lid coupling portion 220, which will be described later. When the extension container 400 is selectively mounted on the main container 100, the main container coupling portion 140 can also be coupled to the lower extension container coupling portion 430 or the container lid coupling portion 220. As will be described later, since the lower extension container coupling portion 430 and the container lid coupling portion 220 are formed in the same shape, the main container coupling portion 140 can be coupled to the lower extension container coupling portion 430 and the container lid coupling portion 220. When the extension container 400 is mounted, the main container coupling portion 140 can be coupled to the lower extension container coupling portion 430. When the extension container 400 is not mounted, the main container coupling portion 140 can be coupled to the container lid coupling portion 220.

[0058] Figure 9 is a side view of the main container handle, the extension container handle, and the container lid in an open state according to the first embodiment of the present disclosure, and Figure 10 is an exploded perspective view of the main container, the extension container, and the container lid according to the first embodiment of the present disclosure.

[0059] Referring to Figure 9 and Figure 10, the container lid 200 opens and closes the accommodation space 110 of the main container 100 or the extended space 410 of the extension container 400, and the container lid 200 can be detachably coupled to the main container 100 or the extension container 400. That is, when the extension container 400 is not coupled to the main container 100, the container lid 200 can cover at least a part of the accommodation space 110 of the main container 100. When the extension container 400 is coupled to the main container 100, the container lid 200 can cover at least a part of the extended space 410 of the extension container 400.

[0060] The container lid 200 may include a container lid body 210, a container lid coupling part 220, and a container lid handle 230. The container lid body 210 covers a part of the accommodation space 110 of the main container 100 or a part of the extended space 410 of the extension container 400, and the container lid body 210 may be formed in the shape of a plate having a through hole 211 formed in the center. The container lid coupling part 220 can be detachably coupled to the main container coupling part 140 or the extension container upper coupling part 440 to be described later. Whether the container lid 200 is opened can be detected by the first safety sensor part 131 and the second safety sensor part 421 described above. When the first safety sensor part 131 and the second safety sensor part 421 are contact types, the container lid 200 may have a sensor operation part formed in a protruding shape capable of contacting the first safety sensor part 131 and the second safety sensor part 421.

[0061] The container lid handle 230 is a part held by the user so that the user can easily carry the container lid 200. The container lid handle 230 can be more firmly coupled to the main container 100 or the extension container 400. That is, the locking hook 240 formed on the container lid handle 230 can be caught and coupled to the locking protrusion 160 of the main container handle 150 described above, or can be caught and coupled to the locking protrusion 460 of the extension container handle 450 to be described later.

[0062] The main body 300 on which the main container 100 is seated can operate the processing member P connected to the main body 300. The main body 300 may include a control module (not shown in the drawings), which controls a motor that operates the processing member P, the rotational speed of the motor, time, etc. The control module may operate the processing member P by operating a screw S coupled to the processing member P. The screw S and the processing member P may rotate at different rotational speeds from each other through a speed reducer or the like. The main body 300 may include a juice extraction part 600, which generates juice by compressing cut food materials put in through the input hole of the main container 100. When the input food materials move downward along the helix of the rotating screw S, the food materials are compressed or crushed by the screw S and the juice extraction container 630. During the above process, the juice may be released to the juice outlet 610 through the release holes formed in the juice extraction container 630, and the residue of the juiced food materials may be released to the residue outlet 620.

[0063] In particular, when the first safety sensor part 131 and the second safety sensor part 421 detect the open state of the main container 100 or the extension container 400, the main body 300 may stop the operation of the processing member P.

[0064] Refer to Figure 4 , the extension container 400 forms an extended space 410 that expands the accommodation space 110 of the main container 100, and the space in the extension container 400 is connected to the accommodation space 110 of the main container 100, and the extension container 400 can be selectively mounted on the main container 100. When the accommodation space 110 of the main container 100 cannot accommodate additional food materials, the extension container 400 can be mounted on the main container 100. Not only can one extension container 400 be mounted stacked on top of each other, but several extension containers 400 can also be mounted stacked one by one.

[0065] The extension container 400 may include an extension container body 420, a lower connection part 430 of the extension container, and an upper connection part 440 of the extension container. The space in the extension container body 420 may be connected to the accommodation space 110 of the main container 100. The extended space 410 of the extension container body 420 can accommodate additional food materials added during food material processing.

[0066] The extended container body 420 can be formed in a cylindrical shape, where the upper and lower portions of the extended container body 420 are open to form an expansion space. The extended container body 420 can be formed in various shapes, such as a cylindrical body or a square cylindrical body with its upper and lower portions open. The extended container body 420 can include side walls 422 that form the expansion space 410. A portion of the side walls 422 can be formed to slope outward as it extends upward. Since a portion of the side walls 422 is sloped, more expansion space 410 can be ensured.

[0067] An extended container lower coupling portion 430 can be formed on one lower side portion of the extended container body 420, and an extended container upper coupling portion 440 can be formed on the upper side portion of the extended container body 420.

[0068] The extended container body 420 can include a second safety sensor portion 421. The second safety sensor portion 421 can detect whether the container lid 200 is opened, similar to the first safety sensor portion 131 of the main container body 130 described above. The detection objects of the second safety sensor portion 421 and the first safety sensor portion 131 are the expansion space 410 of the extended container 400 and the accommodation space 110 of the main container body 130 respectively. The functions and structures of the first safety sensor portion 131 and the second safety sensor portion 421 are the same. The only difference between the first safety sensor portion 131 and the second safety sensor portion 421 is the detection object, and the detailed description of the second safety sensor portion 421 will be omitted.

[0069] When the extended container 400 is installed, it can be determined whether to stop the processing member by detecting the open and closed states of the extended container body 420. When the second safety sensor portion 421 detects the open or closed state of the extended container body 420, the first safety sensor portion 131 can also detect the open or closed state of the extended container body 420 together with the second safety sensor portion 421. Therefore, even when the extended container 400 is installed, the second safety sensor portion 421 is used together with the first safety sensor portion 131, and thus safety accidents can be prevented.

[0070] Figure 11 is Figure 12 a partial exploded view of the handle of the extended container. Figure 12 is a view showing the process of separating the body of the extended container of the juicer from the main container body and opening the lid of the extended container according to the first embodiment of the present disclosure, and Figure 13 is Figure 12 an enlarged view of region XIII.

[0071] Referring to Figures 11 to 13, the extension container handle 450 is the part held by the user, enabling the user to easily carry the extension container 400. The extension container handle 450 can be coupled to the main container handle 150 described above. When the extension container body 420 is mounted on the main container body 130, the lower portion of the extension container handle 450 and the upper portion of the main container handle 150 can be coupled. An insertion groove 451 can be formed in the lower portion of the extension container handle 450 so that a part of the upper portion of the main container handle 150 can be inserted. When the upper portion of the main container handle 150 is inserted and coupled to the insertion groove 451 of the extension container handle 450, the mounted state of the extension container 400 can be stably maintained.

[0072] Referring to Figure 6 , to more stably maintain the mounted state of the extension container 400, a hook portion 452 can be formed on the extension container handle 450. The hook protrusion 452a of the hook portion 452 can be caught on the locking claw 151 formed on the main container handle 150. An unlocking button 453 can be formed on the extension container handle 450, and the unlocking button 453 releases the locked state between the hook protrusion 452a and the locking claw 151. The unlocking button 453 can be formed in a number equal to the number of the hook portions 452. The unlocking button 453 can release the locked state by pushing the hook portion 452. The path along which the hook portion 452 is pushed can be guided by a guiding member 455. By pressing the unlocking button 453, the user can release the locked state between the hook protrusion 452a and the locking claw 151 and separate the extension container 400 from the main container 100.

[0073] In Figure 6 , it is illustrated that the hook portion 452 and the unlocking button 453 are formed on the extension container handle 450, and the locking claw 151 is formed on the main container handle 150. Conversely, the hook portion 452 and the unlocking button 453 can be formed on the main container handle 150, and the hook portion 452 can be formed on the extension container handle 450.

[0074] Returning to the reference Figures 11 to 13 , to enhance the locked state between the hook protrusion 452a and the locking claw 151, an elastically expandable spring 454 can be provided between the hook portions 452. The spring 454 prevents the locked state between the hook protrusion 452a and the locking claw 151 from being easily released, and the spring 454 is preferably a compression spring that resists the compressive force that can push the hook portion 452.

[0075] In addition, the locking protrusion 460 may be formed on the outer surface of the extended container handle 450. As described above, the locking protrusion 460 of the extended container handle 450 may be coupled to the locking hook 240 of the container lid handle 230. Since the locking protrusion 460 of the extended container handle 450 and the locking protrusion 160 of the main container handle 150 have in common that they are captured by the locking hook 240 of the container lid handle 230, the locking protrusion 460 and the locking protrusion 160 may be formed at the same position and in the same shape.

[0076] Referring to Figure 12 , the process of releasing the locked states of the extended container handle 450 and the main container handle 150 and releasing the locked state of the extended container 400 and the container lid handle 230 will be briefly described. First, when the user presses the unlocking button 453, the unlocking button 453 pushes the hook portion 452, and the locked state of the hook protrusion 452a and the locking claw 151 can be released. By releasing the locked state of the hook protrusion 452a and the locking claw 151, the locked states of the extended container handle 450 and the main container handle 150 can be released. In addition, when the user displaces the locking hook 240 of the container lid handle 230, the locked state between the locking hook 240 and the locking protrusion 460 of the extended container handle 450 can be released.

[0077] Meanwhile, a seating groove (not shown in the drawings) may be formed on the lower end portion of the extended container 400 such that the extended container 400 is stably seated on the upper end portion of the main container 100. The seating groove may be formed on the lower end portion of the extended container 400, that is, on the lower end portion of the extended container body 420. By inserting the upper end portion of the main container body 130 into the seating groove, the mounted state of the extended container 400 can be stably maintained. The seating groove may not be formed on the lower end portion of the extended container body 420, but the seating groove may be formed on the upper end portion of the main container body 130. That is, the seating groove may be formed on the lower end portion of the extended container body 420 or on the upper end portion of the main container body 130.

[0078] Referring to Figure 5 , the lower connecting portion 430 of the extended container may be detachably coupled to the main container connecting portion 140.

[0079] The upper connecting portion 440 of the extended container is a portion that is coupled to the above-described container lid connecting portion 220. When the extended container 400 is selectively mounted on the main container 100, the upper connecting portion 440 of the extended container may also be coupled to the container lid connecting portion 220. The container lid connecting portion 220 is the same as the above-described main container connecting portion 140 because the main container connecting portion 140 can be coupled to the container lid connecting portion 220. Therefore, the container lid connecting portion 220 may be formed in a shape that is the same as the shape of the main container connecting portion 140.

[0080] In the above description, considering that the main container connection part 140 is connected to the container lid connection part 220 or the extended container lower connection part 430, and the extended container upper connection part 440 is connected to the container lid connection part 220, the main container connection part 140 and the extended container upper connection part 440 have the same point in the connection structure. The three connection structures can be the same, that is, the connection structure between the main container connection part 140 and the container lid connection part 220, the connection structure between the main container connection part 140 and the extended container lower connection part 430, and the connection structure between the extended container upper connection part 440 and the container lid connection part 220 can be the same.

One side of the lifting part 1500 can be connected to the main container 100, and the other side can be connected to the extension container 2400. Additionally, the container lid 200 can be coupled to the portion of the other side of the lifting platform that is not connected to the extension container 2400. As the length of the lifting part 1500 changes, the extension container 2400 can be exposed in the accommodation space 110 of the main container 100. That is, when the length of the lifting part 1500 becomes longer, the extension container 2400 can be lifted to the upper part of the main container 100.

[0096] Figure 20 is a view showing the process of lifting the extension container according to the third embodiment of the present disclosure.

[0097] Referring to Figure 20 , in a state where the extension container 2400 is completely inserted into the accommodation space 110, the length of the lifting part 1500 becomes longer. As the length of the lifting part 1500 increases, the extension container 2400 is exposed to the outside of the accommodation space 110. When the length of the lifting part 1500 becomes the maximum length, the extension container 2400 is completely exposed to the outside. Conversely, when the length of the lifting part 1500 shortens, the extension container 2400 is inserted into the accommodation space 110.
