Description

food processor

[0001] The present invention relates to a food processing machine, and more specifically, to a food processing machine that performs processing such as grinding, processing, and cooking on food.

[0002] There are various food processing machines that perform tasks such as grinding, mixing, and juicing food.

[0003] Among food processors, there are cooking devices such as mixers and blenders that cook food by at least one of grinding and stirring, as well as cooking devices such as multi-cookers that heat and cook food during processing such as grinding and stirring.

[0004] Accordingly, a food processor capable of heating and cooking must be equipped with a structure that discharges steam so that the pressure inside the container does not become excessively high due to the steam generated during the heating process.

[0005] However, there are cases where the cooking results are unsatisfactory because the moisture in the ingredients is lost due to the release of steam generated during the heating and cooking process. In addition, there is the inconvenience of not being able to immediately check whether the cooking device is in a suitable condition for heating and cooking or whether foreign matter has accumulated inside.

[0006] The problem that the present invention aims to solve is to provide a food processor that prevents excessive evaporation of moisture during the process of heating and processing food.

[0007] Alternatively, it provides a food processor that allows one to intuitively check whether the food processor is in a suitable condition for use, for example, whether it is ready for a heating process or whether food has overflowed inside.

[0008] Alternatively, it provides a food processor in which the cover automatically opens and closes when the user places or removes a container containing food.

[0009] Alternatively, it provides a food processor with improved thermal insulation performance and a vibration / noise reduction effect by a cover surrounding the container.

[0010] Alternatively, it provides a food processor with increased convenience for opening and closing the cover surrounding the container.

[0011] The problems of the present invention are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0012] A food processing machine according to an embodiment of the present invention for solving the above problem comprises: a container including a receiving tank open upward and a handle formed protruding from the receiving tank; a main body on which the container is seated; a cover receiving portion formed extending upward from the main body so as to be located at the rear of the receiving tank; a first side cover provided to be able to move in and out from one side of the cover receiving portion to open or close one side of the receiving tank; a second side cover provided to be able to move in and out from the other side of the cover receiving portion to open or close the other side of the receiving tank; and an upper cover rotatably provided on the upper part of the cover receiving portion to receive the receiving tank and to open or close the upper part of a receiving space surrounded by the cover receiving portion, the first side cover, and the second side cover, wherein at least a portion of the handle is provided to be located outside the upper cover, the first side cover, and the second side cover.

[0013] Other specific details of the present invention are included in the detailed description and drawings.

[0014] According to embodiments of the present invention, at least the following effects are achieved.

[0015] Excessive evaporation of moisture is prevented during the process of heating and processing food.

[0016] Alternatively, convenience is enhanced as users can intuitively check whether the heating unit of the food processor is in a suitable condition for use, or whether food has overflowed inside the processor and needs to be removed.

[0017] Alternatively, as the cover opens or closes in response to the attachment or detachment of the container, the convenience of opening / closing the cover surrounding the container is increased.

[0018] Alternatively, the cover surrounding the container reduces vibration and noise, and improves thermal insulation performance.

[0019] Alternatively, the convenience of opening and closing the cover surrounding the container is increased.

[0054] FIG. 1 is a perspective view illustrating a closed state of a food processor according to one embodiment of the present invention, FIG. 2 is a perspective view illustrating an open state of a food processor according to one embodiment of the present invention, and FIG. 3 is an exploded perspective view of a food processor according to one embodiment of the present invention.

[0055] Referring to FIGS. 1 to 3, a food processor (1) according to one embodiment of the present invention includes a main body (10), a heating part (20), a cover receiving part (30), a container (40), a lid (50), a lid cap (60), a first side cover (70), a second side cover (80), and an upper cover (90).

[0056] The main body (10) is configured such that a container (40) is detachably installed, and may include a power source (e.g., a motor) inside to drive a processing member (e.g., a blade, etc.) included in the container (40). Inside the main body (10), a circuit configuration for controlling the power source and the heating unit (20), and a heat dissipation configuration for releasing heat generated from the power source and the heating unit (20) to the outside may be provided.

[0057] FIG. 4 is a perspective view illustrating a control unit (11) according to an embodiment of the present invention, and FIG. 5 is a front view illustrating an auxiliary display unit (113) according to an embodiment of the present invention. Hereinafter, the auxiliary display unit (113) will be described in detail with reference to FIG. 4 and FIG. 5.

[0058] Referring to FIGS. 1 to 5, the outer surface of the main body (10) has a control unit (11) for controlling the food processor (1), and the control unit (11) may be equipped with a display (111) for displaying the control status of the food processor (1), an operating unit (112) for receiving inputs for controlling a power source and / or a heating unit (20), and an auxiliary display unit (113) for displaying the operation progress, temperature, etc. of the food processor (1) with a plurality of lights.

[0059] Referring to FIG. 4 and others, the display (111) is configured to provide information to the user, such as the manual of the food processor (1), the operating mode selection screen, the operating time of the device, and the time remaining until operation is completed. The display (111) may be equipped with an LED screen, etc.

[0060] The control unit (112) is configured to operate and control the food processor (1). Through the control unit (112), the user may be provided with a rotary control unit (112a) that allows the user to search the manual of the food processor (1) or select a desired operation such as grinding or heating, or a switch-type control unit (112b) that allows the user to receive operation inputs such as selecting a pre-set operation mode or the operating time for operating the machine through clicking or pressing.

[0061] FIG. 4 illustrates, as an example of an operating part (112), a rotary operating part (112a) and a button (112b) arranged around it. However, the operating part (112) is not limited thereto and may include at least one of the operating means such as a touch panel, a rotary switch, a toggle switch, a slide switch, etc.

[0062] The user can search for and view cooking recipes built into the food processor (1) through the display (111) and the control unit (112), and can process food according to a pre-set method. Alternatively, through the control unit (11), the user can view the manual of the food processor (1), the control status of the food processor (1), and information guiding the cooking process using the food processor (1).

[0063] The auxiliary display unit (113) includes a plurality of indicator lights provided around the display (111) and is a status light or light source that provides various brightness or various colors of light. The auxiliary display unit (113) may be provided with LED bulbs, etc., and in FIG. 4, the plurality of indicator lights constituting the auxiliary display unit (113) are shown as having eight light sources of the same size provided at the bottom of the display (111). However, the configuration of the auxiliary display unit (113) is not limited thereto, and a plurality may be provided on the left and right sides or the top and bottom sides of the display (111) using various types of light sources, or may be provided at the corner portions of the display (111). Alternatively, in FIG. 5, a plurality of light sources of the auxiliary display unit (113) are shown as being provided at equal intervals.

[0064] However, in other embodiments, the spacing between multiple light sources may be configured differently, and multiple light sources that display warnings based on the container guide sensor and discharge channel sensor described later may be independently provided separately. For example, the light source provided on the far right may be spaced apart from other light sources at a wider interval, and may display only warnings detected by specific components, such as the discharge channel sensor or the container guide sensor.

[0065] The auxiliary display unit (113) can provide information to the user independently of the operation of the display (111), such as the control status or operation progress of the food processor (1), by using the number of light sources turned on, brightness, color, etc.

[0066] In one embodiment, the auxiliary display unit (113) can indicate the degree to which the container (40) or the food ingredients inside the container (40) are heated by the heating unit (20) by the number of illuminated indicator lights of the auxiliary display unit (113), separately from the number displayed on the display (111). Each light source of the auxiliary display unit (113) may indicate 10C or 20C, etc., so that as the temperature rises, multiple light sources may be illuminated sequentially, and as multiple light sources are illuminated, the brightness of each light source may be controlled to become brighter or redder.

[0067] For example, one indicator light is provided to turn on at intervals of 10°C, so that when four indicator lights are turned on, the user can intuitively be informed that the temperature is in the range of 40°C to 50°C. However, this is not limited thereto, and the temperature interval or color at which the indicator lights turn on can be freely set according to the user's choice.

[0068] Alternatively, in another embodiment, when the food processor (1) is operated by a preset, the progress of the food processor (1) can be displayed using an auxiliary display unit (113). For example, 10% or 20% of the work progress can be displayed per light source of the auxiliary display unit (113). As the work of the food processor (1) progresses, multiple light sources of the auxiliary display unit (113) are sequentially emitted, and the brightness of each light source can be controlled to become brighter as the number of light sources emitting light increases.

[0069] Alternatively, in another embodiment, the auxiliary display unit (113) includes a first auxiliary display unit which is part of a plurality of light sources of the auxiliary display unit (113), and can display information or a warning regarding whether the heating unit (20) is in an operable state through the first auxiliary display unit. For example, the first auxiliary display unit may be at least one of the indicator lights located at both ends of the left and right sides, and the first auxiliary display unit may be used as a light source to indicate the usable state of the heating unit (20). Additionally, for example, if red light is emitted from the first auxiliary display unit, it may indicate that the heating unit (20) is in a state of being prepared for operation, and if green light is emitted, it may indicate that the heating unit (20) is in a usable state.

[0070] However, the display method of the auxiliary display unit (113) is not limited to the above, and the user can freely choose to display the desired information in the desired form on the auxiliary display unit (113) by changing the settings of the food processor (1).

[0071] As described above, information regarding the status of the food processor (1) can be intuitively conveyed to the user separately from the display (111) by using the auxiliary display unit (113). Since the user can easily grasp the desired information without looking at the display (111), the food processor (1) can be conveniently used even when controlling the food processor (1) or performing other tasks while the food processor (1) is in operation.

[0072] The main body (10) may include an upper surface (13) forming the upper part of the front portion where the control unit (11) is provided. The handle (42) of the container (40) is located on the upper surface (13) and may be located on both sides of the upper surface (13). The handle (42) may be formed to protrude outward from the upper surface (13). That is, when the container (40) is mounted on the main body (10), the handle (42) of the container (40) is located outward from the upper cover (90), the first side cover (70), and / or the second side cover (80). Through this, the user can easily take out the container (40) even if some of the first side cover (70), the second side cover (80), and the upper cover (90) are closed.

[0073] According to the embodiment, the end of the handle (42) may be located outside the upper surface (13) but within the footprint of the main body (10). In this case, when inserting or removing the container (40) from the main body (10), the user's hand does not get caught on the upper surface (13), allowing for easy removal. Additionally, when storing or transporting the food processor (1) by packing it in a box, the handle (42) of the container (40) is located within the footprint of the main body (10), making it easy to pack into the box. Furthermore, when using the food processor (1) by placing it in a specific location, the handle (42) is located within the footprint of the main body (10), allowing the food processor (1) to be placed without being obstructed by surrounding objects. Additionally, since the handle (42) of the food processor (1) according to the present embodiment is located within the footprint of the main body (10), it is possible to prevent the user from unintentionally coming into contact with the handle (42). If the handle (42) protrudes outward from the main body (10), the food processor (1) may be knocked over by unintentionally impacting the handle (42) while passing by the food processor (1) or by the user's clothes getting caught on the handle (42).

[0074] Referring to FIGS. 1 and 3, a heating unit (20) is provided on the upper part of the main body (10) and forms a heating space (21) that accommodates a container (40). The heating unit (20) provides heat to a receiving tank (41) accommodated within the heating space (21) to heat food ingredients accommodated inside the receiving tank (41).

[0075] The heating unit (20) may include a heating coil surrounding the heating space (21). Alternatively, the heating unit (20) may include a coil capable of transferring heat through induction heating. Alternatively, the heating unit (20) may be configured to supply high-temperature air to the heating space (21).

[0076] Referring to FIGS. 1 to 3, the cover receiving portion (30) is formed to extend upward from the main body (10) so as to be located at the rear of the receiving tank (41). The cover receiving portion (30) accommodates the first side cover (70) and the second side cover (80) so as to be retractable.

[0077] The first side cover (70) and the second side cover (80) are received inside the cover receiving portion (30) in an open state (see FIG. 2). FIG. 2 illustrates the first side cover (70) and the second side cover (80) being received inside the cover receiving portion (30) with only a portion open. In the open state, only a portion of the first side cover (70) is exposed to one side of the cover receiving portion (30), and most of it can be received inside the cover receiving portion (30). In the open state, only a portion of the second side cover (80) is exposed to the other side of the cover receiving portion (30), and most of it can be received inside the cover receiving portion (30).

[0078] In the closed state (see FIG. 1), the first side cover (70) moves along the upper edge of the main body (10) from one side of the cover receiving portion (30) and closes one side of the receiving tank (41) from the outside. That is, in the closed state (see FIG. 1), the first side cover (70) is positioned to extend from the cover receiving portion (30) and surround one side of the receiving tank (41).

[0079] In the closed state (see FIG. 1), the second side cover (80) moves along the upper edge of the main body (10) from the other side of the cover receiving portion (30) and closes the other side of the receiving tank (41) from the outside. That is, in the closed state (see FIG. 1), the second side cover (80) is positioned to extend from the cover receiving portion (30) and surround the other side of the receiving tank (41).

[0080] Although not illustrated in the drawing, the first side cover (70) and the second side cover (80) may be arranged to overlap each other within the cover receiving portion (30) in the open state. To prevent the first side cover (70) and the second side cover (80) from interfering with each other during the transition between the open state and the closed state, the path of movement of the first side cover (70) and the path of movement of the second side cover (80) may be separated from each other. For example, the path of movement of the second side cover (80) may be formed inside the path of movement of the first side cover (70). Conversely, the path of movement of the second side cover (80) may be formed outside the path of movement of the first side cover (70).

[0081] A more detailed description of the first side cover (70) and the second side cover (80) will be provided later.

[0082] Referring to FIGS. 1 to 3, the upper cover (90) may be rotatably provided on the upper part of the cover receiving portion (30). The upper cover (90) may be elastically supported with respect to the cover receiving portion (30) using an elastic member, such as a spring, provided on the pivot axis, and the elastic member may provide elastic force in the direction in which the upper cover (90) opens.

[0083] The upper cover (90) may have a second steam discharge hole (94) formed vertically through the central part. The second steam discharge hole (94) is a space in which at least a portion of the lid cap (60), described later, is accommodated.

[0084] The upper cover (90) comes into contact with the upper part of the cover receiving portion (30), the upper part of the first side cover (70), and the upper part of the second side cover (80) in the closed state (see FIG. 1). Thus, in the closed state, the upper cover (90) closes the upper part of the receiving space surrounded by the cover receiving portion (30), the first side cover (70), and the second side cover (80).

[0085] The upper cover (90) opens the upper part of the receiving space surrounded by the cover receiving portion (30), the first side cover (70), and the second side cover (80) in an open state (see FIG. 2), thereby allowing the container (40) received in the receiving space to be removed.

[0086] Referring to FIG. 2, the lower surface (91) of the upper cover (90) is in contact with the upper surface of the cover receiving portion (30), the first side cover (70), and the second side cover (80).

[0087] A flap receiving groove (93) may be formed in the lower surface (91) to receive the upper portions of the first side cover (70) and the second side cover (80). To prevent steam from leaking between the first side cover (70) and the second side cover (80) and the lower surface (91), the flap receiving groove (93) may be formed in a sealing member having excellent sealing and adhesion capabilities.

[0088] Through this structure, steam generated in the container (40) is prevented from being discharged between the upper cover (90) and the first side cover (70) and / or the second side cover (80), thereby preventing the user from unintentionally suffering burns from the steam.

[0089] Referring to FIG. 2, the lower surface (91) may be provided with coupling hooks (95a, 95b) that maintain the connection between the upper cover (90) and the cover receiving portion (30) in a closed state. On the upper surface of the cover receiving portion (30), a first hook groove (31a) to which the first coupling hook (95a) is coupled and a second hook groove (31b) to which the second coupling hook (95b) is coupled may be formed.

[0090] The first coupling hook (95a) and the second coupling hook (95b) can each be elastically supported by an elastic member such as a spring, and the elastic member can provide an elastic force to move the first coupling hook (95a) and the second coupling hook (95b) to the coupling position for the first hook groove (31a) and the second hook groove (31b), respectively.

[0091] Referring to FIG. 3, the container (40) may include a receiving tank (41) that is open upward and receives food ingredients, and a handle (42) formed protruding from the receiving tank (41). Although not illustrated, a processing member (e.g., a blade) for processing food ingredients may be provided inside the receiving tank (41). The processing member may be connected to a drive shaft exposed on the upper surface of the main body (10) to receive rotational force.

[0092] The main body (10) can be configured so that the container (40) is seated with the handle (42) positioned at the front.

[0093] Referring to FIGS. 2 and 3, the lid (50) seals the upper edge of the receiving tank (41) and is detachably coupled to the receiving tank (41). The lid cap (60) is detachably coupled to the lid (50) through a first steam discharge hole (58) formed in the center of the lid (50).

[0094] The lead (50) and lead cap (60) will be described in detail with reference to FIGS. 5 to 9.

[0095] FIG. 6 is a perspective view illustrating a lid cap of a food processor according to one embodiment of the present invention, FIG. 7 is a cross-sectional view of a lid cap of a food processor according to one embodiment of the present invention, FIG. 8 is a cross-sectional view illustrating a combined state of a lid and a lid cap of a food processor according to one embodiment of the present invention, FIG. 9 is a perspective view illustrating a combined state of a lid and a lid cap of a food processor according to one embodiment of the present invention, and FIG. 10 is a plan view illustrating a combined state of a lid and a lid cap of a food processor according to one embodiment of the present invention.

[0096] Referring to FIGS. 6 and 7, the lead cap (60) includes a stem (61), a stem projection (62), a steam blocking part (63), and an extension stem (64).

[0097] The stem (61) extends downward from the steam blocking part (63) and is inserted into the first steam discharge hole (58) of the lid (50). The stem (61) is installed to form a gap with the first steam discharge hole (58). This is to allow steam generated during the process of heating food ingredients by the heating part (20) inside the tank (41) to be discharged to the outside of the lid (50) through the gap between the stem (61) and the first steam discharge hole (58).

[0098] To this end, in this embodiment, the first steam discharge hole (58) and the stem (61) are configured to have a circular cross-section, but the shape of the first steam discharge hole (58) and the stem (61) can be varied in many ways if a gap can be formed between the first steam discharge hole (58) and the stem (61).

[0099] The stem protrusion (62) may be formed to protrude from both sides of the stem (61). The stem protrusion (62) is configured to secure the lead cap (60) to the lead (50). A detailed explanation thereof will be provided later.

[0100] The steam blocking section (63) covers the upper part of the stem (61) and is formed to extend laterally.

[0101] Referring to FIGS. 8 and FIGS. 10, the steam blocking part (63) is located above the first steam discharge hole (58) and can cover the entire vertical upper portion of the first steam discharge hole (58) so that the first steam discharge hole (58) is not visible when viewed from above by the steam blocking part (63). This is to ensure that the steam discharged through the first steam discharge hole (58) is retained and condensed by the steam blocking part (63). To enhance the steam retention effect, the steam blocking part (63) may be formed with a curvature that forms a downward slope toward the edge. That is, the steam blocking part (63) may have an umbrella shape that is convex upward overall.

[0102] Referring to FIG. 10, the steam blocking section (63) may be formed with different lengths in the horizontal and vertical directions. For example, the steam blocking section (63) may be formed in an elliptical shape as shown in FIG. 10.

[0103] The steam blocking section (63) may be composed of a first steam blocking section (63a) forming a long axis and a second steam blocking section (63b) forming a short axis.

[0104] The first steam blocking part (63a) can be supported on the upper surface of the lead (50). The lead cap (60) can be fixed to the lead (50) such that the first steam blocking part (63a) is supported on the upper surface of the lead (50) and the stem projection (62) is supported on the lower surface of the lead (50). For a secure fixation of the lead cap (60), the stem projection (62) can be configured to be located at the lower part of the first steam blocking part (63a).

[0105] Referring to FIG. 8, the second steam blocking part (63b) may be formed to be spaced apart from the upper surface of the lid (50). A steam discharge space (57) is formed between the upper surface of the lid (50) and the second steam blocking part (63b).

[0106] Steam discharged through the first steam discharge hole (58) stays at the bottom of the steam blocking section (63), some of it condenses and liquefies, the liquefied steam is returned to the receiving tank (41), and the unliquefied steam is discharged through the steam discharge space (57).

[0107] Referring to FIG. 7, the extension stem (64) extends upward from the steam blocking section (63).

[0108] The extension stem (64) can be used as a handle during the process of installing / removing the lid cap (60) from the lid (50). To increase grip strength, the extension stem (64) may be formed to have a shape that expands laterally as it extends upward. The extension stem (64) can be accommodated within the second steam discharge hole (94) of the upper cover (90).

[0109] Referring to FIGS. 3 and FIGS. 8, the lead (50) may include a rim (51), an insertion part (52), a contact member (53), a side part (54), an upper part (55), an inclined part (56), and a first steam discharge hole (58).

[0110] The rim (51) is formed to rest on the top edge of the tank (41).

[0111] The insertion part (52) is formed to extend downward from the rim (51). The insertion part (52) is inserted into the interior of the tank (41) and comes into contact with or adheres to the inner wall of the tank (41).

[0112] The sealing member (53) is installed on the outer side of the insertion part (52) and is in close contact with the inner wall of the receiving tank (41). The sealing member (53) improves the sealing force between the lid (50) and the receiving tank (41) to prevent liquid or steam from being discharged between the lid (50) and the receiving tank (41).

[0113] The side portion (54) is formed to extend upward from the rim (51). The side portion (54) may be formed to extend upward in an oblique slope. In other words, the side portion (54) may be formed in a shape where the diameter decreases as it goes upward. This is to ensure that steam rising from the tank (41) condenses and liquefies at the side portion (54) and then falls back into the tank (41). This minimizes moisture evaporation during the food processing process.

[0114] The upper surface (55) is formed to extend inward from the side surface (54).

[0115] The inclined portion (56) forms a downward slope from the upper portion (55) and extends to the first steam discharge hole (58).

[0116] The space formed by the side portion (54), the top portion (55), and the inclined portion (56) is located higher than the first steam discharge hole (58). Therefore, steam entering the space formed by the side portion (54), the top portion (55), and the inclined portion (56) stays in that space to be discharged to the first steam discharge hole (58), and the condensed water liquefied during the stay falls back into the tank (41), thereby minimizing moisture evaporation during the food processing process.

[0117] Additionally, referring to FIG. 8, the space formed by the indentation of the inclined portion (56) can form a space in which a lid cap (60) is received. The first steam blocking portion (63a) and the second steam blocking portion (63b) can be supported by the inclined portion (56), and the steam discharge space (57) can be formed between the inclined portion (56) and the second steam blocking portion (63b).

[0118] Referring to FIG. 8, the lid (50) includes a coupling groove (59) formed by being recessed from the first steam discharge hole (58). The coupling groove (59) is a space into which the stem projection (62) of the lid cap (60) is inserted.

[0119] On the lower surface of the lead (50), a guide groove (59a) may be formed that extends from the coupling groove (59) and guides the stem projection (62) in the coupling direction.

[0120] The lead cap (60) is coupled to the lead (50) in such a way that when the lead cap (60) is rotated in the coupling direction after the stem projection (62) is inserted into the coupling groove (59), the stem projection (62) moves a certain distance along the guide groove (59a). The lead cap (60) can be coupled to the lead (50) by rotating approximately 90 degrees from the position where the stem projection (62) is inserted into the coupling groove (59).

[0121] After the lid cap (60) is attached to the lid (50), the connection groove (59) is opened. Therefore, the condensate condensed in the steam blocking section (63) falls onto the inclined section (56) and then flows along the inclined section (56) into the connection groove (59) and into the interior of the receiving tank (41).

[0122] A second embodiment of the present invention will be described below.

[0123] FIG. 11 is a perspective view showing the closed state of a food processor according to the second embodiment of the present invention, FIG. 12 is a perspective view showing the open state of a food processor according to the second embodiment of the present invention, and FIG. 13 is an exploded perspective view of a food processor according to the second embodiment of the present invention.

[0124] Referring to FIGS. 11 to 13, a food processor (2) according to a second embodiment of the present invention includes a main body (210), a heating part (220), a cover receiving part (230), a container (240), a lid (250), a lid cap (260), a first side cover (270), a second side cover (280), and an upper cover (290).

[0125] The main body (210) is configured such that a container (240) is detachably installed, and may include a power source (e.g., a motor) inside to drive a processing member (e.g., a blade, etc.) included within the container (240). Inside the main body (210), a circuit configuration for controlling the power source and the heating unit (220), a heat dissipation configuration for releasing heat generated from the power source and the heating unit (220) to the outside, etc., may be provided.

[0126] Referring to FIG. 11 and the like, the outer surface of the main body (210) may be provided with a display (211) that displays the control status of the food processor (2) and an operating unit (212) that receives inputs for controlling the power source and / or heating unit (220). FIG. 11 and the like shows a dial as an example of the operating unit (212), but the operating unit (211) is not limited thereto and may include at least one of the operating means such as a button or a touch panel. Additionally, the user can search for and view cooking recipes through the display (211), and can view the instruction manual of the food processor (2) or view the control status of the food processor (2) and information guiding the cooking process using the food processor (2) through the display (211).

[0127] The main body (210) may include an upper surface (213) forming the upper part of the front portion where the display (211) is provided. The upper surface (213) may be located below the handle (242) of the container (240). The upper surface (213) may be formed to protrude outward from the handle (242). That is, when the container (240) is mounted on the main body (210), the handle (242) of the container (240) is located outward from the upper cover (290), the first side cover (270), and / or the second side cover (280), but may be located within the footprint of the main body (210).

[0128] If the handle (242) protrudes outward from the main body (210), the food processor (2) may be knocked over if the user unintentionally strikes the handle (242) while passing by the food processor (2) or if the user's clothes get caught on the handle (242).

[0129] However, in the food processor (2) according to the present embodiment, an upper surface (213) is formed on the lower part of the handle (242) of the container (240), so that the handle (242) of the container (240) is located within the footprint of the main body (210), so the possibility of the above-described situation occurring is significantly low.

[0130] Referring to FIGS. 11 and 13, a heating unit (220) is provided on the upper part of the main body (210) and forms a heating space (21) that accommodates the lower part of the container (240). The heating unit (220) provides heat to a receiving tank (241) accommodated within the heating space (21) to heat food ingredients accommodated inside the receiving tank (241).

[0131] The heating unit (220) may include a heating coil surrounding the heating space (21). Alternatively, the heating unit (220) may include a coil capable of transferring heat through induction heating. Alternatively, the heating unit (220) may be configured to supply high-temperature air to the heating space (21).

[0132] Referring to FIGS. 11 to 13, the cover receiving portion (230) is formed to extend upward from the main body (210) so as to be located at the rear of the receiving tank (241). The cover receiving portion (230) accommodates the first side cover (270) and the second side cover (280) so as to be retractable.

[0133] The first side cover (270) and the second side cover (280) are received inside the cover receiving portion (230) in an open state (see FIG. 12). In the open state, only a portion of the first side cover (270) is exposed to one side of the cover receiving portion (230), and most of it can be received inside the cover receiving portion (230). In the open state, only a portion of the second side cover (280) is exposed to the other side of the cover receiving portion (230), and most of it can be received inside the cover receiving portion (230).

[0134] In the closed state (see FIG. 11), the first side cover (270) moves from one side of the cover receiving portion (230) along the upper edge of the main body (210) toward the handle (242) of the container (240) and closes one side of the receiving tank (241) from the outside. That is, in the closed state (see FIG. 11), the first side cover (270) is positioned to extend from the cover receiving portion (230) and surround one side of the receiving tank (241).

[0135] In the closed state (see FIG. 11), the second side cover (280) moves from the other side of the cover receiving portion (230) along the upper edge of the main body (210) toward the handle (242) of the container (240) and closes the other side of the receiving tank (241) from the outside. That is, in the closed state (see FIG. 11), the second side cover (280) is positioned to extend from the cover receiving portion (230) and surround the other side of the receiving tank (241).

[0136] In the open state, the first side cover (270) and the second side cover (280) may be arranged to overlap each other inside the cover receiving portion (230) (see FIG. 26). In order to prevent the first side cover (270) and the second side cover (280) from interfering with each other during the transition between the open state and the closed state, the path of movement of the first side cover (270) and the path of movement of the second side cover (280) may be separated from each other. For example, the path of movement of the second side cover (280) may be formed inside the path of movement of the first side cover (270). Conversely, the path of movement of the second side cover (280) may be formed outside the path of movement of the first side cover (270).

[0137] A more detailed description of the first side cover (270) and the second side cover (280) will be provided later.

[0138] Referring to FIGS. 11 to 13, the upper cover (290) may be rotatably provided on the upper part of the cover receiving portion (230). The upper cover (290) may be elastically supported with respect to the cover receiving portion (230) using an elastic member, such as a spring, provided on the pivot axis, and the elastic member may provide elastic force in the direction in which the upper cover (290) opens.

[0139] The upper cover (290) may have a second steam discharge hole (294) formed vertically through the central part. The second steam discharge hole (294) is a space in which at least a portion of the lid cap (260), which will be described later, is accommodated.

[0140] The upper cover (290) comes into contact with the upper part of the cover receiving portion (230), the upper part of the first side cover (270), and the upper part of the second side cover (280) in the closed state (see FIG. 11). Thus, in the closed state, the upper cover (290) closes the upper part of the receiving space surrounded by the cover receiving portion (230), the first side cover (270), and the second side cover (280).

[0141] The upper cover (290) opens the upper part of the receiving space surrounded by the cover receiving portion (230), the first side cover (270), and the second side cover (280) in an open state (see FIG. 12), thereby allowing the container (240) received in the receiving space to be removed.

[0142] Referring to FIG. 12, the lower surface (291) of the upper cover (290) is in contact with the upper surface of the cover receiving portion (230), the first side cover (270), and the second side cover (280).

[0143] A flap receiving groove (293) may be formed in the lower surface (291) to receive the upper portions of the first side cover (270) and the second side cover (280). To prevent steam from leaking between the first side cover (270) and the second side cover (280) and the lower surface (291), the flap receiving groove (293) may be formed in a sealing member having excellent sealing and adhesion capabilities.

[0144] Through this structure, steam generated in the container (240) is prevented from being discharged between the upper cover (290) and the first side cover (270) / second side cover (280), thereby preventing the user from unintentionally suffering burns from the steam.

[0145] Referring to FIG. 12, the lower surface (291) may be provided with coupling hooks (295a, 295b) that maintain the connection between the upper cover (290) and the cover receiving portion (230) in a closed state. On the upper surface of the cover receiving portion (230), a first hook groove (231a) to which the first coupling hook (295a) is coupled and a second hook groove (231b) to which the second coupling hook (295b) is coupled may be formed.

[0146] The first coupling hook (295a) and the second coupling hook (295b) may each be elastically supported by an elastic member such as a spring, and the elastic member may provide an elastic force to move the first coupling hook (295a) and the second coupling hook (295b) to a coupling position for the first hook groove (231a) and the second hook groove (231b), respectively.

[0147] Referring to FIG. 13, the container (240) may include a receiving tank (241) that is open upward and receives food ingredients, and a handle (242) formed protruding from the receiving tank (241). Although not illustrated, a processing member (e.g., a blade) for processing food ingredients may be provided inside the receiving tank (241). The processing member may be connected to a drive shaft exposed on the upper surface of the main body (210) to receive rotational force.

[0148] The main body (210) can be configured so that the container (240) is seated with the handle (242) positioned at the front.

[0149] Referring to FIGS. 12 and 13, the lid (250) seals the upper edge of the receiving tank (241) and is detachably coupled to the receiving tank (241). The lid cap (260) is detachably coupled to the lid (250) through a first steam discharge hole (258) formed in the center of the lid (250).

[0150] The lead (250) and lead cap (260) will be described in detail with reference to FIGS. 14 to 18.

[0151] FIG. 14 is a perspective view illustrating a lid cap of a food processor according to a second embodiment of the present invention, FIG. 15 is a cross-sectional view of a lid cap of a food processor according to a second embodiment of the present invention, FIG. 16 is a cross-sectional view illustrating a combined state of a lid and a lid cap of a food processor according to a second embodiment of the present invention, FIG. 17 is a perspective view illustrating a combined state of a lid and a lid cap of a food processor according to a second embodiment of the present invention, and FIG. 18 is a plan view illustrating a combined state of a lid and a lid cap of a food processor according to a second embodiment of the present invention.

[0152] Referring to FIGS. 14 and 15, the lead cap (260) includes a stem (261), a stem projection (262), a steam blocking portion (263), and an extension stem (264).

[0153] The stem (261) extends downward from the steam blocking part (263) and is inserted into the first steam discharge hole (258) of the lid (250). The stem (261) is installed to form a gap with the first steam discharge hole (258). This is to allow steam generated during the process of heating food ingredients by the heating part (220) inside the tank (241) to be discharged to the outside of the lid (250) through the gap between the stem (261) and the first steam discharge hole (258).

[0154] To this end, in this embodiment, the first steam discharge hole (258) is configured to be circular and the stem (261) is configured to have a roughly square cross-section, but the shapes of the first steam discharge hole (258) and the stem (261) can be varied in many ways if a gap can be formed between the first steam discharge hole (258) and the stem (261).

[0155] The stem protrusion (262) may be formed to protrude from both sides of the stem (261). The stem protrusion (262) is configured to secure the lead cap (260) to the lead (250). A detailed explanation thereof will be provided later.

[0156] The steam blocking portion (263) covers the upper part of the stem (261) and is formed to extend laterally.

[0157] Referring to FIGS. 16 and 18, the steam blocking part (263) is located above the first steam discharge hole (258) and can cover the entire vertical upper portion of the first steam discharge hole (258) so that the first steam discharge hole (258) is not visible when viewed from above by the steam blocking part (263). This is to ensure that the steam discharged through the first steam discharge hole (258) is retained and condensed by the steam blocking part (263). To enhance the steam retention effect, the steam blocking part (263) may be formed with a curvature that forms a downward slope toward the edge. That is, the steam blocking part (263) may have an umbrella shape that is convex upward overall.

[0158] Referring to FIG. 18, the steam blocking section (263) may be formed with different lengths in the horizontal and vertical directions. For example, the steam blocking section (263) may be formed in an elliptical shape as shown in FIG. 18.

[0159] The steam blocking section (263) may be composed of a first steam blocking section (263a) forming a long axis and a second steam blocking section (263b) forming a short axis.

[0160] The first steam blocking portion (263a) may be supported on the upper surface of the lid (250). The lid cap (260) may be fixed to the lid (250) such that the first steam blocking portion (263a) is supported on the upper surface of the lid (250) and the stem projection (262) is supported on the lower surface of the lid (250). For a secure fixation of the lid cap (260), the stem projection (262) may be configured to be located at the lower part of the first steam blocking portion (263a).

[0161] Referring to FIG. 16, the second steam blocking portion (263b) may be formed to be spaced apart from the upper surface of the lid (250). A steam discharge space (257) is formed between the upper surface of the lid (250) and the second steam blocking portion (263b).

[0162] Steam discharged through the first steam discharge hole (258) remains at the bottom of the steam blocking section (263), some of which condenses and liquefies, and the unliquefied steam is discharged through the steam discharge space (257).

[0163] Referring to FIG. 15, the extension stem (264) extends upward from the steam blocking section (263).

[0164] The extension stem (264) can be used as a handle during the process of installing / removing the lid cap (260) from the lid (250). To increase grip strength, the extension stem (264) may be formed to have a shape that expands laterally as it extends upward. The extension stem (264) may be accommodated within the second steam discharge hole (294) of the upper cover (290).

[0165] Referring to FIGS. 13 and 16, the lead (250) may include a rim (251), an insertion part (252), a sealing member (253), a side part (254), an upper part (255), an inclined part (256), and a first steam discharge hole (258).

[0166] The rim (251) is formed to rest on the top edge of the tank (241).

[0167] The insertion portion (252) is formed to extend downward from the rim (251). The insertion portion (252) is inserted into the interior of the tank (241) and comes into contact with or adheres to the inner wall of the tank (241).

[0168] The sealing member (253) is installed on the outer side of the insertion part (252) and is in close contact with the inner wall of the receiving tank (241). The sealing member (253) improves the sealing force between the lid (250) and the receiving tank (241) to prevent liquid or steam from being discharged between the lid (250) and the receiving tank (241).

[0169] The side portion (254) is formed to extend upward from the rim (251). The side portion (254) may be formed to extend upward in an oblique slope. In other words, the side portion (254) may be formed in a shape where the diameter decreases as it goes upward. This is to ensure that when steam rising from the tank (241) condenses and liquefies in the side portion (254), it falls back into the tank (241). This minimizes moisture evaporation during the food processing process.

[0170] The upper surface (255) is formed to extend inward from the side surface (254).

[0171] The inclined portion (256) forms a downward slope from the upper portion (255) and extends to the first steam discharge hole (258).

[0172] The space formed by the side portion (254), the top portion (255), and the inclined portion (256) is located higher than the first steam discharge hole (258). Therefore, steam entering the space formed by the side portion (254), the top portion (255), and the inclined portion (256) stays in the space to be discharged to the first steam discharge hole (258), and the condensed water liquefied during the stay falls back into the tank (241), thereby minimizing moisture evaporation during the food processing process.

[0173] Additionally, referring to FIG. 16, the space formed by the indentation of the inclined portion (256) can form a space in which a lid cap (260) is received. The first steam blocking portion (263a) can be supported by the inclined portion (256), and the steam discharge space (257) can be formed between the inclined portion (256) and the second steam blocking portion (263b).

[0174] Referring to FIG. 17, the lid (250) includes a coupling groove (259) formed by a recess from the first steam discharge hole (258). The coupling groove (259) is a space into which the stem projection (262) of the lid cap (260) is inserted.

[0175] On the lower surface of the lead (250), a guide groove (259a) may be formed that extends from the coupling groove (259) and guides the stem projection (262) in the coupling direction.

[0176] The lead cap (260) is coupled to the lead (250) in such a way that when the lead cap (260) is rotated in the coupling direction after the stem projection (262) is inserted into the coupling groove (259), the stem projection (262) moves a certain distance along the guide groove (259a). The lead cap (260) can be coupled to the lead (250) by rotating approximately 90 degrees from the position where the stem projection (262) is inserted into the coupling groove (259).

[0177] Referring to FIG. 17, after the lid cap (260) is coupled to the lid (250), the coupling groove (259) is opened. Therefore, the condensate condensed in the steam blocking section (263) falls onto the inclined section (256) and then flows along the inclined section (256) into the coupling groove (259) and into the interior of the receiving tank (241).

[0178] FIG. 19 is a perspective view showing a food processor (1) with the container (40) removed according to one embodiment of the present invention.

[0179] Referring to FIG. 19, a container receiving space (12) capable of receiving a container (40) is formed in the main body (10). The main body (10) may include a container guide part (14) for easily connecting the container (40) to the main body (10), a cushion protrusion (15) for preventing noise generated during operation of the food processor (1), and a discharge channel (16) for discharging food ingredients or contents to the outside when they overflow from the container (40).

[0180] The container guide section (14) is configured to have an inclined surface to smoothly insert the container (40) into the main body (10), and the inclined surface may be formed in the shape of a curved surface. In FIG. 19, the container guide section (14) is shown as being provided in the shape of an inclined surface on the cover receiving section (30), but the container guide section (14) may be provided with an inclined surface independently of the cover receiving section (30).

[0181] As shown in FIG. 19, the container guide portion (14) can be positioned in the rear direction of the container (40) when the container (40) is combined, so as not to interfere with the first side cover (70) and the second side cover (80).

[0182] The main body (10) is provided with a container guide part (14) in which at least a portion of the outer surface of the container (40) is guided into the container receiving space (12), thereby allowing the container (40) to be smoothly and easily connected to the main body (10). During the process of cooking food, the user may be performing various tasks simultaneously, or there may be a situation where heavy ingredients are placed in the container (40) or the contents may overflow. At this time, the invention according to the present embodiment is provided with a container guide part (14) so ​​that when the user connects the container (40) to the main body (10), the user can easily connect it without requiring much attention, thereby allowing the user to focus more on the cooking process.

[0183] Additionally, the container guide section (14) may include a container guide section sensor (not shown) that detects the temperature of the container receiving space (12) or the temperature of the main body (10) surrounding the container receiving space (12). If the heat generated by the heating section (20) does not cool sufficiently and is higher than a preset temperature, the user may be warned not to insert the container (40). The temperature serving as the criterion for the warning can be set according to the user's choice, for example, a warning may be issued when it is 60°C or higher.

[0184] When the temperature detected by the container guide sensor is higher than the preset range, a warning can be given to the user through the display (111) or the auxiliary display (113). For example, when a warning is given through the auxiliary display (113), the warning display may be performed in the form of the entire light source of the auxiliary display (113) flashing rapidly, or the warning may be displayed on the first auxiliary display described above and expressed in the form of emitting light in a specific color or flashing.

[0185] In another embodiment, if the heating unit (20) is in a temperature range unsuitable for use, the first auxiliary indicator may be lit in red. If the heating unit (20) is in a temperature range suitable for use, the first auxiliary indicator may be lit in green. The first auxiliary indicator lit in this way may be assigned to indicate the usage status of the heating unit (20).

[0186] Referring to FIG. 19, the main body (10) includes a plurality of cushion protrusions (15) formed to protrude toward the container receiving space (12) along the perimeter of the outer surface on which the container (40) is seated. The cushion protrusions (15) are configured to suppress noise generated when the main body (10) and the container (40) collide with each other by filling the gap between the main body (10) and the container (40). The cushion protrusions (15) may be provided along the part where the main body (10) and the container (40) come into contact on the side of the heating unit (20).

[0187] The cushion protrusion (15) may be made of an elastic material such as a rubber member. It may be provided to fill the gap created when the main body (10) and the container (40) are joined together. Alternatively, noise may be suppressed by preventing the main body (10) and the container (40) from colliding with each other due to vibrations generated when the food processor (1) is operated.

[0188] Referring to FIG. 19, a discharge channel (16) is formed at the bottom of the container receiving space (12) of the main body (10) in which the container (40) is received. When operating the food processor (1), food ingredients or contents received in the container (40) may overflow into the container receiving space (12), and the food ingredients accumulated in the container receiving space (12) can be discharged to the outside through the discharge channel (16).

[0189] By providing a discharge channel (16), it is possible to prevent contents that overflow outside the container (40) during the operation of the food processor (1) or during the process of attaching or detaching the container (40) or moving the food processor (1) from accumulating inside the main body (10) or leaking into the drive shaft that drives the blade. For example, the discharge channel (16) is provided to discharge contents accumulated inside the main body (10) to the outside of the main body.

[0190] Additionally, the discharge channel (16) may include a discharge channel sensor (not shown) that detects whether food ingredients that have overflowed into the container receiving space (12) are accumulated. In order to prevent leakage of the drive shaft, etc., caused by food ingredients accumulating within the container receiving space (12), if food ingredients are accumulated within the receiving space (12), the discharge channel sensor may give a warning to the user through the display (111) or the auxiliary display unit (113). For example, when giving a warning through the auxiliary display unit (113), the warning display may be performed with at least a portion of the light source of the auxiliary display unit (113) maintaining a predetermined color and being lit. Alternatively, in another embodiment, the auxiliary display unit (113) includes a second auxiliary display unit among a plurality of indicator lights, and the warning from the discharge channel sensor may be displayed by the second auxiliary display unit, and the second auxiliary display unit may be displayed in the form of emitting a specific color or blinking.

[0191] In one embodiment, among the plurality of indicator lights of the auxiliary display unit (113), the first auxiliary display unit and the second auxiliary display unit described above may be provided to be distinguished from each other.

[0192] In one embodiment, among the plurality of indicator lights of the auxiliary display unit (113), the first auxiliary display unit and the second auxiliary display unit described above may have at least one indicator light in common.

[0193] In one embodiment, the indication by the first auxiliary indicator showing whether the heating unit (20) is available for use may be displayed alternately with a time difference from the indication by the second auxiliary indicator that warns when the discharge path sensor detects food ingredients.

[0194] Alternatively, in another embodiment, the indication of whether the heating unit (20) is available and the warning indication by the exhaust flow sensor may be displayed separately by independent indicator lights. For example, two indicator lights on both sides of the edge may be assigned for the warning indication by the exhaust flow sensor, or an indicator light may be separately provided at the top of the display (111) to separately display the warning by the exhaust flow sensor.

[0195] The main body (10) further includes a trigger switch (17) that operates in conjunction with the attachment and detachment of the container (40). The trigger switch (17) may be equipped with an electronic sensor such as a proximity sensor or a magnetic sensor. Alternatively, the trigger switch (17) may be provided in a physical form that is pressed when the container (40) is attached and is restored to an unpressed state by elastic force, etc., when the container (40) is detached.

[0196] In one embodiment, when the trigger switch (17) is pressed as the container (40) is seated on the main body (10), the first side cover (70) and the second side cover (80) described above may be closed. The user may select the range or magnitude of pressure at which the trigger switch (17) is pressed and operated. For example, the first side cover (70) and the second side cover (80) may not be closed when the container (40) is simply seated, but may be closed when the container (40) is additionally pressed downward.

[0197] In addition, in one embodiment, when the trigger switch (17) is restored to an unpressed state as the container (40) is detached from the main body (10), the first side cover (70) and the second side cover (80) described above are opened, and the upper cover (90) can also be opened as the first side cover (70) and the second side cover (80) are opened.

[0198] The operation of the above trigger switch (17) can be operated in conjunction with a member such as a fixing pin (114) described later.

[0199] FIG. 20 is a perspective view illustrating the internal structure of the upper cover of a food processor according to one embodiment of the present invention.

[0200] Referring to FIGS. 2 and FIGS. 20, the upper cover (90) may include a first coupling hook (96b) provided to be exposed downward from one side and a second coupling hook (96a) provided to be exposed downward from the other side. The first coupling hook (96b) and the second coupling hook (96a) may be exposed through the first lower surface (91) of the upper cover (90).

[0201] On the upper surface of the cover receiving portion (30), a first hook groove (31b) to which a first coupling hook (96b) is coupled and a second hook groove (31a) to which a second coupling hook (96a) is coupled may be formed.

[0202] The first coupling hook (96b) and the second coupling hook (96a) can each be elastically supported by an elastic member such as a spring, and the elastic member can provide an elastic force to move the first coupling hook (96b) and the second coupling hook (96a) to the coupling position for the first hook groove (31b) and the second hook groove (31a), respectively.

[0203] Referring to FIGS. 2 and FIGS. 20, the upper cover (90) may include a first unlock projection (95b) provided to be exposed downward from one side and a second unlock projection (95a) provided to be exposed downward from the other side. The first unlock projection (95b) and the second unlock projection (95a) may be exposed through the first lower surface (91) of the upper cover (90).

[0204] On the upper surface of the cover receiving portion (30), a first unlock groove (32b) through which a first unlock projection (95b) passes and a second unlock groove (32a) through which a second unlock projection (95a) passes may be formed. When the upper cover (90) is in a closed state, the end of the first unlock projection (95b) may pass through the first unlock groove (32b) and be located inside the cover receiving portion (30), and the end of the second unlock projection (95a) may pass through the second unlock groove (32a) and be located inside the cover receiving portion (30).

[0205] Referring to FIG. 20, the inner side of the upper cover (90) is provided with a first connecting rod (97b) connecting a first unlock projection (95b) and a first connecting hook (96b), and a second connecting rod (97a) connecting a second unlock projection (95a) and a second connecting hook (96a).

[0206] Accordingly, since the first coupling hook (96b) and the first unlock projection (95b) move in conjunction, the first unlock projection (95b) can be moved to move the first coupling hook (96b) from the coupling position to the unlocking position. Similarly, since the second coupling hook (96a) and the second unlock projection (95a) move in conjunction, the second unlock projection (95a) can be moved to move the second coupling hook (96a) from the coupling position to the unlocking position.

[0207] FIG. 21 is an exploded perspective view showing a first side cover, a second side cover, and a side cover driving unit of a food processor according to one embodiment of the present invention, FIG. 22 is a perspective view showing the upper part of the first side cover, a second side cover, and a side cover driving unit of a food processor according to one embodiment of the present invention in an assembled state, FIG. 23 is a perspective view showing the lower part of the first side cover, a second side cover, and a side cover driving unit of a food processor according to one embodiment of the present invention in an assembled state.

[0208] Referring to FIGS. 21 to 23, the first side cover (70) may be formed in the shape of an arc of approximately 180 degrees. On one side of the first side cover (70), a first lower flap (71) and a first upper flap (72) are arranged vertically, and between the first lower flap (71) and the first upper flap (72), a first slit (73) is formed by being recessed from one side.

[0209] A first unlock tab (74) is formed at the top of the first side cover (70) to have a step.

[0210] The first unlock tab (74) enters the cover receiving portion (30) when the first side cover (70) moves from a closed state to an open state and pushes out the first unlock projection (95b, see FIG. 20) located on the inside of the cover receiving portion (30). As the first unlock projection (95b) moves from the coupled position to the unlocked position by the first unlock tab (74), the first coupling hook (96b) also moves from the coupled position to the unlocked position, thereby enabling the upper cover (90) to be switched to an open state.

[0211] The first upper flap (72) may include a protruding piece (72a) that extends forward. The protruding piece (72a) allows the user to easily move the first side cover (70) from a closed state to an open state. The user can move the first side cover (70) from a closed state to an open state by pushing the protruding piece (72a) formed perpendicular to the rotation axis of the first side cover (70).

[0212] Referring to FIGS. 21 to 23, the second side cover (80) may be formed in the shape of an arc of approximately 180 degrees. On the other side of the second side cover (80), a second lower flap (81) and a second upper flap (82) are arranged vertically, and a second slit (83) is formed by being recessed from one side between the second lower flap (81) and the second upper flap (82).

[0213] Although not illustrated, when the second side cover (80) is in a closed state, the second upper flap (82) is located above the handle (42). Also, although not illustrated, the second lower flap (81) is located between the handle (42) and the receiving tank (41), and the second slit (83) receives the handle (42) so that the handle (42) passes through it.

[0214] When the first side cover (70) and the second side cover (80) are in a closed state, the first lower flap (71) and the second lower flap (81) overlap forward, and the first upper flap (72) and the second upper flap (82) overlap forward. The first upper flap (72), on which the protruding piece (72a) is formed, may be positioned further forward than the second upper flap (82).

[0215] The first upper flap (72) and the second upper flap (82) can be received in an overlapping state in the flap receiving groove (93) formed on the second lower surface (92) of the upper cover (90).

[0216] In the closed state, the first side cover (70) and the second side cover (80) overlap around the handle (42), thereby increasing the noise blocking effect and minimizing the leakage of heat provided from the heating unit (20), so the heat retention effect is increased.

[0217] In addition, since the handle (42) is received in the first slit (73) of the first side cover (70) and the second slit (83) of the second side cover (80) in the closed state, the upper, lower, left, and right sides of the handle (42) are all supported by the first side cover (70) and the second side cover (80), and the vibration of the container (40) can be suppressed more effectively.

[0218] A second unlock tab (84) is formed on the top of the second side cover (80) to have a step.

[0219] The second unlock tab (84) enters the cover receiving portion (30) when the second side cover (80) moves from a closed state to an open state and pushes out the second unlock projection (95a, see FIG. 20) located on the inside of the cover receiving portion (30). As the second unlock projection (95a) moves from the coupled position to the unlocked position by the second unlock tab (84), the second coupling hook (96a) also moves from the coupled position to the unlocked position, thereby enabling the upper cover (90) to be switched to an open state.

[0220] When both the first side cover (70) and the second side cover (80) move from a closed state to an open state, the connection between the upper cover (90) and the cover receiving portion (30) is released through the interaction of the first unlock tab (74), the first unlock projection (95b), and the first coupling hook (96b), and the interaction of the second unlock tab (84), the second unlock projection (95a), and the second coupling hook (96a). Subsequently, the upper cover (90) automatically switches to an open state by means of elastic force.

[0221] That is, as the first side cover (70) and the second side cover (80) move from a closed state to an open state, the upper cover (90) automatically switches from a closed state to an open state.

[0222] Referring to FIGS. 21 to 23, the first side cover (70) is coupled to the first moving part (120), and the second side cover (80) is coupled to the second moving part (130). The first moving part (120) and the second moving part (130) are movably coupled to the interlocking part (140).

[0223] The first moving part (120) may be configured in a ring shape, and the first side cover (70) is fixed to one side of the first moving part (120) and switches between a closed state and an open state by the rotation of the first moving part (120).

[0224] A fixing groove (122) into which a fixing pin (114, see FIG. 24) described later is inserted may be formed on one side of the first moving part (120). A first gear (121) that meshes with an interlocking gear part (142) may be formed on the side of the first moving part (120).

[0225] The second moving part (130) may also be configured in a ring shape, and the second side cover (80) is fixed to the other side of the second moving part (130) and switches between a closed state and an open state by the rotation of the second moving part (130).

[0226] A second gear (131) that meshes with the interlocking gear part (142) may be formed on the side of the second moving part (130).

[0227] The interlocking part (140) may have a circular guide receiving groove (141) formed on its upper surface to accommodate the first moving part (120) and the second moving part (130) and to guide the movement of the first moving part (120) and the second moving part (130). The interlocking part (140) may include an interlocking gear part (142) installed adjacent to the guide receiving groove (141).

[0228] The interlocking gear unit (142) enables the movement of the first side cover (70) and the second side cover (80) to be interlocked. The interlocking gear unit (142) may have a gear structure such that when the first side cover (70) moves from a closed state to an open state, the second side cover (80) also moves from a closed state to an open state, and when the first side cover (70) moves from an open state to a closed state, the second side cover (80) also moves from an open state to a closed state. That is, the interlocking gear unit (142) can enable the other side cover (80) to rotate in the opposite direction when either the first side cover (70) or the second side cover (80) rotates in one direction.

[0229] Accordingly, by simply moving only the first side cover (70) from a closed state to an open state, the second side cover (80) moves from a closed state to an open state, and as the first side cover (70) and the second side cover (80) move from a closed state to an open state, the upper cover (90) automatically moves from a closed state to an open state as described above. That is, by simply moving only the first side cover (70) from a closed state to an open state, the second side cover (80) and the upper cover (90) also switch from a closed state to an open state, so user convenience is greatly improved.

[0230] Referring to FIG. 22, the first moving part (120) and the second moving part (130) can be installed stacked within the guide receiving groove (141). For example, the second moving part (130) can be located below the first moving part (120).

[0231] Referring to FIG. 22, the first side cover (70) may be provided on the outside of the second side cover, and the movement path of the first side cover (70) and the movement path of the second side cover (80) may be configured so as not to intersect each other in order to prevent mutual interference between the first side cover (70) and the second side cover (80).

[0232] Referring to FIG. 23, the interlocking part (140) may include an elastic member (143) that stores elastic force when the first side cover (70) and the second side cover (80) are in an open state. That is, the elastic member (143) may provide elastic force to move the first side cover (70) and the second side cover (80) from an open state to a closed state. The elastic member (143) may be a spring that contracts when the first moving part (120) moves from a closed state to an open state.

[0233] FIG. 24 is a perspective view illustrating the upper cover interlocking part, etc. of a food processing machine according to one embodiment of the present invention.

[0234] Referring to FIG. 24, a fixing pin (114) may be provided inside the cover receiving portion (30) to operate in conjunction with the opening and closing of the upper cover (90) or to operate in conjunction with a trigger switch (not shown).

[0235] The fixing pin (114) can be detached from the fixing groove (122) depending on the operation of the trigger switch (17).

[0236] In one embodiment, the trigger switch (17) and the fixing pin (114) are respectively connected to both sides of the link that moves in a seesaw motion around the pivot axis (112), so that they can be linked as described above.

[0237] The fixed pin (114) can be provided with an elastic force in a downward direction by the elastic member (116).

[0238] For example, the switching operation between the open and closed states of a food processor can operate as follows.

[0239] In one embodiment, when the first side cover (70), the second side cover (80), and the top cover (90) are in an open state, the fixing pin (114) is inserted into the fixing groove (122) to prevent the first moving part (120) from moving to a closed state by the elastic force of the elastic member (143, see FIG. 23). Since the movement of the first moving part (120) is restricted, the second moving part (130) also remains in an open state. Therefore, as long as the top cover (90) remains in an open state, the first side cover (70) and the second side cover (80) also remain in an open state.

[0240] In the case where the trigger switch (17) has a configuration connected to the fixing pin (114), when the user places the container (40) and the trigger switch (17) is pressed (first closing step), the fixing pin (114) rises and is released from the fixing groove (122). Since the first moving part (120) and the second moving part (130) are moved to a closed state by the elastic force of the elastic member (143, see FIG. 23), the first side cover (70) and the second side cover (80) are switched from an open state to a closed state (second closing step).

[0241] That is, the first side cover (70) and the second side cover (80) are automatically switched from an open state to a closed state simply by the user placing the container (40).

[0242] In another embodiment, when the first side cover (70), the second side cover (80) and the top cover (90) are in a closed state, and the user detaches the container (40) from the main body (10) using the handle (42), the first side cover (70) is moved from a closed state to an open state by the trigger switch (17), and the second side cover (80) is moved from a closed state to an open state in conjunction with the first side cover (70) (first opening step).

[0243] When both the first side cover (70) and the second side cover (80) move from a closed state to an open state, the connection between the upper cover (90) and the cover receiving portion (30) is released through the interaction of the first unlock tab (74), the first unlock projection (95b), and the first coupling hook (96b), and the interaction of the second unlock tab (84), the second unlock projection (95a), and the second coupling hook (96a). Subsequently, the upper cover (90) automatically switches to an open state by means of elastic force (second opening step).

[0244] That is, by simply the action of the user detaching the container (40) to switch the first side cover (70) from a closed state to an open state, the upper cover (90) and the second side cover (80) are automatically switched from a closed state to an open state.

[0245] In another embodiment, the first side cover (70), the second side cover (80), and the top cover (90) may be opened and closed by an opening drive motor. An opening drive motor may be provided for each of the first side cover (70), the second side cover (80), and the top cover (90), or one opening drive motor may be provided to drive the first side cover (70) and the second side cover (80) simultaneously, and the top cover (90) may be driven by a separate opening drive motor.

[0246] A trigger switch (17) provided on the main body (10) can sense when the container (40) is attached to and detached from the main body (10). For example, the trigger switch (17) may be equipped with a proximity sensor using infrared rays, lasers, etc., a capacitive displacement sensor that detects a change in distance between the container (40) and the trigger switch (17), an inductive sensor, a magnetic sensor, etc. When the trigger switch (17) detects that the container (40) is detached from the main body (10), it may be equipped to operate an opening drive motor to open at least one of the first side cover (70), the second side cover (80), and the top cover (90). Additionally, when the trigger switch (17) detects that the container (40) is attached to the main body (10), it may be equipped to operate an opening drive motor to close at least one of the first side cover (70), the second side cover (80), and the top cover (90).

[0247] Through this, even when the container (40) or heating unit (20) is in operation and difficult to grasp directly with the hand, the user can easily attach and detach the container (40) to the main body (10) by gripping the handle (42), and the first side cover (70) and the second side cover (80) surrounding the container (40) are automatically opened or closed in response to attachment and detachment, thereby increasing the user's convenience.

[0248] A second embodiment of the present invention will be described below.

[0249] FIG. 25 is an exploded perspective view illustrating a first side cover, a second side cover, and a side cover driving unit of a food processor according to a second embodiment of the present invention; FIG. 26 is a perspective view illustrating an assembled state of a first side cover, a second side cover, and a side cover driving unit of a food processor according to a second embodiment of the present invention; FIG. 27 is a perspective view illustrating a lower part of a side cover driving unit of a food processor according to a second embodiment of the present invention; and FIG. 28 is a perspective view illustrating a state in which the upper cover is removed in a closed state of a food processor according to a second embodiment of the present invention.

[0250] Referring to FIGS. 25 to 27, the first side cover (270) may be formed in the shape of an arc of approximately 90 to 120 degrees. On one side of the first side cover (270), a first lower flap (271) and a first upper flap (272) are arranged vertically, and between the first lower flap (271) and the first upper flap (272), a first slit (273) is formed by being recessed from one side.

[0251] Referring to FIG. 28, when the first side cover (270) is in a closed state, the first lower flap (271) is positioned between the handle (242) and the receiving tank (241), the first upper flap (272) is positioned above the handle (242), and the first slit (273) receives the handle (242) so that the handle (242) passes through it.

[0252] The first upper flap (272) may include a protruding piece (272a) that extends forward. The protruding piece (272a) allows the user to easily move the first side cover (270) from a closed state to an open state. The user can move the first side cover (270) from a closed state to an open state by pushing the protruding piece (272a) formed perpendicular to the rotation axis of the first side cover (270).

[0253] Referring to FIGS. 25 to 27, the second side cover (280) may be formed in the shape of an arc of approximately 90 to 120 degrees. On the other side of the second side cover (280), a second lower flap (281) and a second upper flap (282) are arranged vertically, and a second slit (283) is formed by being recessed from one side between the second lower flap (281) and the second upper flap (282).

[0254] Referring to FIG. 28, when the second side cover (280) is in a closed state, the second upper flap (282) is located above the handle (242). Also, although not shown, the second lower flap (281) is located between the handle (242) and the receiving tank (241), and the second slit (283) receives the handle (242) so that the handle (242) passes through it.

[0255] When the first side cover (270) and the second side cover (280) are in a closed state, the first lower flap (271) and the second lower flap (281) overlap forward, and the first upper flap (272) and the second upper flap (282) overlap forward. The first upper flap (272), on which the protruding piece (272a) is formed, may be positioned further forward than the second upper flap (282).

[0256] The first upper flap (272) and the second upper flap (282) can be received in an overlapping state in a flap receiving groove (293) formed in the upper cover (290).

[0257] In the closed state, the first side cover (270) and the second side cover (280) overlap around the handle (242), thereby increasing the noise blocking effect and minimizing the leakage of heat provided from the heating unit (220), thereby increasing the heat retention effect.

[0258] Additionally, in the closed state, the handle (242) is received in the first slit (273) of the first side cover (270) and the second slit (283) of the second side cover (280), so that the upper, lower, left, and right sides of the handle (242) are all supported by the first side cover (270) and the second side cover (280), and the vibration of the container (240) can be suppressed more effectively.

[0259] Referring to FIGS. 25 to 27, the first side cover (270) is formed to extend upward from the first support member (275), and the first support member (275) can be coupled with the first moving member (2120). For stable support of the first side cover (270), at least one first reinforcing rib (274) may be provided between the first side cover (270) and the first support member (275).

[0260] The second side cover (280) is formed to extend upward from the second support member (285), and the second support member (285) can be coupled with the second moving member (2130). For stable support of the second side cover (280), at least one second reinforcing rib (284) may be provided between the second side cover (280) and the second support member (285).

[0261] The first moving part (2120) and the second moving part (2130) are movably coupled to the interlocking part (2140).

[0262] The first moving part (2120) may be configured in a ring shape, and the first side cover (270) is fixed to one side of the first moving part (2120) and switches between a closed state and an open state by the rotation of the first moving part (2120).

[0263] A fixing groove (2122) into which a fixing pin (114, see FIG. 29) described later is inserted may be formed on one side of the first moving part (2120). A first gear (2121) that meshes with an interlocking gear part (2142) may be formed on the side of the first moving part (2120).

[0264] The second moving part (2130) may also be configured in a ring shape, and the second side cover (280) is fixed to the other side of the second moving part (2130) and switches between a closed state and an open state by the rotation of the second moving part (2130).

[0265] A second gear (2131) that meshes with the interlocking gear part (2142) may be formed on the side of the second moving part (2130).

[0266] The interlocking part (2140) may have a circular guide receiving groove (2141) formed on its upper surface to accommodate the first moving part (2120) and the second moving part (2130) and to guide the movement of the first moving part (2120) and the second moving part (2130). The interlocking part (2140) may include an interlocking gear part (2142) installed adjacent to the guide receiving groove (2141).

[0267] The interlocking gear unit (2142) enables the movement of the first side cover (270) and the second side cover (280) to be interlocked. The interlocking gear unit (2142) may have a gear structure such that when the first side cover (270) moves from a closed state to an open state, the second side cover (280) also moves from a closed state to an open state, and when the first side cover (270) moves from an open state to a closed state, the second side cover (280) also moves from an open state to a closed state. That is, the interlocking gear unit (2142) may enable the other side cover (280) to rotate in the opposite direction when either the first side cover (270) or the second side cover (280) rotates in one direction.

[0268] Accordingly, by simply moving only the first side cover (270) from a closed state to an open state, the second side cover (280) moves from a closed state to an open state, and as the first side cover (270) and the second side cover (280) move from a closed state to an open state, the upper cover (290) automatically moves from a closed state to an open state as described above. That is, by simply moving only the first side cover (270) from a closed state to an open state, the second side cover (280) and the upper cover (290) also switch from a closed state to an open state, thereby greatly improving user convenience.

[0269] Referring to FIG. 26, the first moving part (2120) and the second moving part (2130) can be installed stacked within the guide receiving groove (2141). For example, the second moving part (2130) can be located below the first moving part (2120).

[0270] Referring to FIG. 26, the first side cover (270) may be provided on the outside of the second side cover, and the movement path of the first side cover (270) and the movement path of the second side cover (280) may be configured so as not to intersect each other in order to prevent mutual interference between the first side cover (270) and the second side cover (280).

[0271] Referring to FIG. 27, the interlocking part (2140) may include an elastic member (2143) that stores elastic force when the first side cover (270) and the second side cover (280) are in an open state. That is, the elastic member (2143) may provide elastic force to move the first side cover (270) and the second side cover (280) from an open state to a closed state. The elastic member (2143) may be a spring that contracts when the first moving part (2120) moves from a closed state to an open state.

[0272] Meanwhile, when the first side cover (270) and the second side cover (280) move from a closed state to an open state, the coupling hooks (295a, 295b) can be actuated to disengage the connection with the hook grooves (231a, 231b). In this case, when the user moves the first side cover (270) and the second side cover (280) from a closed state to an open state, the connection between the coupling hooks (295a, 295b) and the hook grooves (231a, 231b) is released, and the upper cover (290) can be automatically opened.

[0273] FIG. 29 is a perspective view illustrating the upper cover interlocking part, etc. of a food processing machine according to a second embodiment of the present invention.

[0274] Referring to FIG. 29, the interior of the cover receiving portion (230) is provided with an opening / closing detection portion (2111) and a fixing pin (2114) that operate in conjunction with the opening / closing of the upper cover (290).

[0275] The end of the opening / closing detection part (2111) is exposed through the upper surface of the cover receiving part (230) (see FIG. 28). The opening / closing detection part (2111) is lowered by the lower surface (291) when the upper cover (290) is in a closed state, and is raised by the elastic force of the elastic member (2115) when the upper cover (290) is in an open state.

[0276] In conjunction with the lifting operation of the opening / closing detection unit (2111), the fixing pin (2114) is lowered and inserted into the fixing groove (2122) when the upper cover (290) is in an open state, and rises and is removed from the fixing groove (2122) when the upper cover (290) is in a closed state.

[0277] For example, the opening / closing detection unit (2111) and the fixing pin (2114) are each connected to both sides of the link (2113) that moves in a seesaw motion around the pivot axis (2112), so that they can be linked as described above.

[0278] The fixing pin (2114) can be provided with an elastic force in a downward or upward direction by the elastic member (2116).

[0279] FIG. 30 is a diagram illustrating the operation of switching between the open state and the closed state of a food processor according to a second embodiment of the present invention.

[0280] When the first side cover (270), the second side cover (280), and the top cover (290) are in an open state, the fixing pin (2114) is inserted into the fixing groove (2122) to prevent the first moving part (2120) from moving to a closed state by the elastic force of the elastic member (2143, see FIG. 27). Since the movement of the first moving part (2120) is restricted, the second moving part (2130) also remains in an open state. Therefore, as long as the top cover (290) remains in an open state, the first side cover (270) and the second side cover (280) also remain in an open state.

[0281] When the user switches the upper cover (290) from an open state to a closed state (C1), the opening / closing detection unit (2111) descends and the fixing pin (2114) rises and is released from the fixing groove (2122). Since the first moving unit (2120) and the second moving unit (2130) are moved to a closed state by the elastic force of the elastic member (2143, see FIG. 27), the first side cover (270) and the second side cover (280) are switched from an open state to a closed state (C2).

[0282] That is, by simply switching the upper cover (290) from an open state to a closed state, the first side cover (270) and the second side cover (280) are automatically switched from an open state to a closed state.

[0283] When the first side cover (270), the second side cover (280) and the top cover (290) are in a closed state, the user moves the first side cover (270) from a closed state to an open state using the protruding piece (272a), and the second side cover (280) moves from a closed state to an open state in conjunction with the first side cover (270) (O1).

[0284] When both the first side cover (270) and the second side cover (280) move from a closed state to an open state, the connection between the coupling hook (295a, 295b) and the hook groove (231a, 231b) is released, and the upper cover (290) is automatically switched to an open state by elastic force (O2).

[0285] That is, by simply switching the first side cover (270) from a closed state to an open state, the upper cover (290) and the second side cover (280) are automatically switched from a closed state to an open state.

[0286] A person skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims set forth below rather than by the detailed description above, and all modifications or variations derived from the meaning and scope of the claims and equivalent concepts should be interpreted as being included within the scope of the present invention.
