Description

Blender

[0001] The present invention relates to a magnetic blender, which is a processing device that rotates a blade through magnetic force, and which is capable of rotating without a separate rotational drive shaft for the main body and the container, and which has a hand-trapping prevention structure that prevents the problem of hands being caught due to a strong magnetic force when the main body and the container are combined.

[0002] Mixing and blending devices, such as blenders and mixers, used to process food and beverages are common in general household applications. These devices typically include a main container and a lid that covers the open end of the main container, hermetically sealing the contents to be processed within the container. These containers are often used to contain processed foods or beverages. Food is typically processed using a blade assembly attached to the top of a rotating shaft.

[0003] A major drawback of conventional food processing equipment is that the container in which the food is to be processed is mechanically attached to the housing by means of various holders and mechanical couplings.

[0004] Therefore, conventional blenders are connected using mechanical couplings, and there is a problem in that the noise is loud during operation, and when the blades are blocked by food during food processing, the rotation drive is restricted and it is not easy to remove the blockage, which causes damage to the agitator motor.

[0005] To improve this, Korean Patent Publication No. 10-2019-7015821 (August 7, 2019) and others propose a food and beverage processing device that places components of a magnetic coupling driven by magnetic force on the base and the lid of the container, respectively, and rotates a blade through magnetic force.

[0006] However, conventional processing devices have a problem in that when a user picks up a container and attaches it to the base, the end of the lower side of the container and the end of the base come into contact with the joining surface, causing the user's finger to get caught due to the strong magnetic force when the base and the container are joined.

[0007] As a related prior art document, Republic of Korea Patent Publication No. 10-2019-7015821 (August 7, 2019) is published.

[0008] An object of the present invention is to provide a magnetic blender having a hand-trapping prevention structure that can prevent a hand from being caught when a container is combined with the main body by forming a side wall that protrudes upward from the main body and can guide the container to move to a fixed position.

[0009] Another object of the present invention is to provide a magnetic blender having a hand-trapping prevention structure in which a side wall protruding upward from the main body is formed to support the palm when combining or removing the main body and the container, thereby making combining and removing stable and easy.

[0010] In order to achieve the above technical task, a magnetic blender having a hand-trapping prevention structure according to the present invention comprises: a main body including a motor and an upwardly protruding side wall; a container positioned on an upper portion of the main body and separately arranged, the container having an open space at an upper portion; and a lid for closing or opening the open space of the container; the main body is provided with a first magnetic assembly driven by the motor and has a seating portion on which the lid can be seated when coupled with the lid; a support surface is formed on a lower portion of the lid so as to be seated and supported on the seating portion of the main body, and a second magnetic assembly capable of magnetic coupling with the first magnetic assembly of the main body is provided, and a blade connected to the second magnetic assembly; when the support surface of the lid is coupled to the seating portion of the main body by a strong magnetic force, the side wall prevents a hand from being trapped.

[0014] In addition, in the magnetic blender having a hand-trapping prevention structure according to the present invention, the mounting portion of the main body is provided with a zigzag-shaped protrusion having a partial slope so that the support surface of the lid can be accurately mounted; and the support surface of the lid is provided with a zigzag-shaped protrusion having a partial slope corresponding to the protrusion provided on the mounting portion, so that the lid can be positioned and coupled through the slope of the protrusion.

[0015] In addition, in a magnetic blender having a hand-trapping prevention structure according to the present invention, at least one coupling safety device that recognizes a lid may be formed on the mounting portion of the main body.

[0016] In addition, in the magnetic blender having the hand-trapping prevention structure according to the present invention, the side walls are formed at a certain interval to facilitate the joining of the mounting portion and the support surface.

[0017] In addition, in the magnetic blender having the hand-jamming prevention structure according to the present invention, the side wall is formed in an arc shape; and the arc shape can be formed in a shape that gradually narrows from the upper end to the lower end.

[0018] According to the present invention, by forming a side wall that protrudes upward from the main body, it has the effect of preventing hands from being caught when the container is combined with the main body.

[0019] In addition, according to the present invention, it has the effect of being able to guide the container to move to a fixed position when combined with the main body.

[0034] Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the attached drawings.

[0035] The advantages and features of the present invention and the method for achieving them will become clear with reference to the embodiments described in detail below together with the attached drawings.

[0036] However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and these embodiments are provided only 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 invention, and the present invention is defined only by the scope of the claims.

[0037] In addition, when describing the present invention, if it is determined that related known technologies may obscure the gist of the present invention, a detailed description thereof will be omitted.

[0038] Referring to FIGS. 1 to 12, a magnetic blender having a hand-trapping prevention structure according to the present invention includes a main body (100), a container (200), and a lid (210), and the main body (100) includes a motor (130) and a magnetic assembly connected to the motor (130), and the magnetic assembly can be formed of at least one magnet.

[0039] Additionally, the main body may include a control unit (170) that controls the operation of the mixer.

[0040] More specifically, as illustrated in FIGS. 1 to 12, the main body (100) may include a motor and an upwardly protruding side wall (105).

[0041] The container (200) is located on the upper part of the main body (100), is arranged separately, and has an open space at the top.

[0042] The lid (210) can close or open the open space of the container (200).

[0043] In addition, the main body (100) may be provided with a first magnetic assembly (150) driven by a motor (130) and may be provided with a mounting portion (110) on which the lid (210) can be mounted when combined with the lid (210).

[0044] In addition, a support surface (216) is formed on the lower part of the lid (210) so as to be supported by being secured to the mounting portion (110) of the main body (100), and a second magnetic assembly (250) capable of magnetic coupling with the first magnetic assembly (150) of the main body (100) may be provided.

[0045] Additionally, the lid (210) may include a blade (220) connected to a second magnetic assembly (250).

[0046] It is characterized in that the support surface (216) of the lid (210) is joined to the mounting portion (110) of the main body (100) by a strong magnetic force through the magnetic assembly of the main body and the lid, thereby preventing hand pinching by the side wall (105).

[0047] In addition, one side of the container (200) is provided with an insertion portion (201) that can be inserted and combined with a lid (210), one side of the lid (210) is provided with an insertion groove (211) into which the insertion portion (201) of the container (200) is combined, and the container (200) and the lid (210) may each be provided with a joining portion (202, 212) so that they can be screw-joined when combined.

[0048] That is, the insertion part (201) of the container (200) may be provided with a joining part (202), and the lid (200) may be provided with a joining part (212) of the lid (200) formed so that the joining part (202) of the container (200) is joined to the part where the insertion part (201) is inserted.

[0049] In addition, a zigzag-shaped protrusion (111) having a partial slope is formed and provided on the mounting portion (110) of the main body (100) so that the support surface (216) of the lid (210) can be accurately mounted, and a zigzag-shaped protrusion (217) having a partial slope corresponding to the protrusion (111) provided on the mounting portion (110) is formed on the supporting surface (216) of the lid (210), so that the main body (100) and the lid (210) can be properly positioned and coupled through the slopes of each protrusion (111, 217).

[0050] Additionally, at least one coupling safety device (115) that recognizes the lid (210) may be formed on the mounting portion (110) of the main body (100).

[0051] That is, the combination safety device (115) is formed with at least one contact portion (215) provided at the bottom of the lid (210), so that the combination safety device (115) can recognize the contact portion (215) to check whether the lid (210) is normally connected, and thereby recognize the container (200) connected to the lid (210).

[0052] In one embodiment, the coupling safety device (115) may be formed in a micro switch manner or may be formed in a hall sensor manner.

[0053] Therefore, if the container (200) is not recognized in the mounting portion (110) of the main body (100), the motor does not operate.

[0054] By this, the blade can be rotated through the driving force of the motor only when the second magnetic assembly (250) of the lid (210) and the first magnetic assembly (150) of the main body (100) are coupled by magnetic force.

[0055] That is, in one embodiment of the present invention, the support surface (216) of the lid (210) is coupled to the mounting portion (110) of the main body (100), and can be coupled by the magnetic force of the first magnetic assembly (150) of the main body (100) and the second magnetic assembly (250) including at least one magnet in the lid (210).

[0056] In addition, with reference to FIG. 11, a magnetic blender having a hand-trapping prevention structure according to the present invention may have a side wall (105) of a main body (100) formed with an inner slope (106) that gradually slopes in the direction of the central axis from the upper end to the lower end, and an outer slope (107) that gradually slopes in the outward direction from the lower end to the upper end.

[0057] At this time, the inner slope (106) can be positioned by magnetic force through the slope of the inner slope (106) when the container (200) is not positioned properly on the main body (100) but is placed on the inner slope (106) of the side wall (105).

[0058] Additionally, the side wall (105) may have an edge portion (108) formed between the inner slope (106) and the outer slope (107).

[0059] That is, when a user holds the container (200) or lid (210) with his / her hand and attaches it to the main body (100), the hand is prevented from entering the space between the mounting portion (110) and the support surface (216) by the side wall (105).

[0060] By forming a side wall (105) that protrudes upward from the main body (100), it has the effect of preventing a hand from being caught by the side wall (105) when combined with the main body.

[0061] In addition, the side walls (105) are formed at regular intervals to facilitate the joining of the mounting portion (110) and the support surface (216).

[0062] That is, even if the user's finger enters the space between the mounting portion (216) and the side wall (105), the finger is pushed from the inner slope (106) to the edge portion (108) or the outer slope (107) and prevented from being caught in the hand.

[0063] If the side wall (105) is not separated from the main body (105), a hand may get caught in the narrow space between the main body (100) and the side wall (105), and also, the free space for the support surface (216) to be combined with the mounting portion (110) is limited, so that the combination is limited to vertical only, making it difficult to combine and remove.

[0064] Therefore, the distance between the side wall (105) and the main body (100) has the effect of facilitating the joining of the mounting portion (110) and the support surface (216).

[0065] Additionally, the side wall (105) can be formed in an arc shape with the upper part gradually widening.

[0066] That is, the arc shape can be formed in a form that gradually narrows from the top to the bottom.

[0067] By this, when the support surface (216) is joined to the mounting portion (110), the support surface (216) has the effect of being able to enter and join in multiple directions without being restricted in direction.

[0068] Additionally, the arc shape can be moved to a fixed position by the inner slope (106) of the side wall or the arc-shaped slope when the support surface (216) is not completely joined to the mounting portion (110).

[0069] That is, it can serve to guide the first magnetic assembly (150) of the main body and at least one magnet of the lid to be positioned correctly by magnetic force.

[0070] Additionally, it goes without saying that the side wall (105) can be formed not only in an arc shape but also in other shapes.

[0071] Additionally, the side wall (105) can serve as a support for joining or detaching the container (200).

[0072] In particular, when the support surface (216) is combined with the mounting portion (110), the side wall (105) can support the palm while preventing the hand from getting caught, and when the support surface (216) is removed from the mounting portion (110), the palm can be easily removed using the principle of a lever while being supported by the side wall.

[0073] By this, the palm is supported when combining or removing the container from the main body, which has the effect of making combining and removing stable and easy.

[0074] At this time, in order to easily remove it, the principle of leverage (removing it sideways while applying downward force) must be used, and unlike conventional magnetic blenders that require one hand to hold the main body and the other to remove the container, this has the effect of allowing easy removal while supporting the side wall with one hand.

[0075] Therefore, according to the present invention, by forming a side wall that protrudes upward from the main body, it has the effect of preventing hand pinching when the container is combined with the main body.

[0076] In addition, according to the present invention, it has the effect of being able to guide the container to move to a fixed position when combined with the main body.

[0077] In addition, according to the present invention, the palm is supported when the container is combined with or separated from the main body, thereby providing the effect of stable and easy combination and separation.

[0078] Although specific embodiments of the magnetic blender having the hand-jamming prevention structure of the present invention have been described so far, it is obvious that various modifications are possible within the scope of the present invention.

[0079] Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the utility model claims described below but also by equivalents of the utility model claims.

[0080] That is, it should be understood that the above-described embodiments are exemplary in all respects and not restrictive, and the scope of the present invention is indicated by the utility model claims to be described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the utility model claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
