Description

[Technical Field]

[0001] The present invention relates to a cooking appliance equipped with a cooking utensil that rotates within a cooking cup, such as a mixer, juicer, or food processor, and more specifically to a cooking appliance that prevents the intake and exhaust holes in the lid from being blocked by the food being cooked. [Background technology]

[0002] In cooking appliances such as blenders, juicers, and food processors, ingredients are crushed, chopped, grated, smashed, chopped, or stirred using a cooking tool that rotates within a cooking cup. The cooking cup is composed of a cup into which ingredients are placed and a lid that covers the cup. To ensure smooth opening and closing and to prevent the cooking cup from being pressurized and causing the ingredients to splash, the lid has a single intake and exhaust hole near the center. To prevent the ingredients from leaking out through this intake and exhaust hole, a protruding rib is provided around the intake and exhaust hole on the upstream side of the rotation direction of the ingredients (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 63-290534 Summary of the Invention [Problem to be solved by the invention]

[0004] Depending on the direction in which the food is swirling, the food may enter the intake and exhaust holes, causing the food to leak out and block the intake and exhaust holes.

[0005] In the case of a vertical mixer 11 in which the rotation axis of the cooking implement is vertical as in Patent Document 1, the food 90 rotates in a horizontal plane perpendicular to the vertical axis (see arrow R3 in Figure 23(c)). Therefore, leakage of the food from the intake and exhaust holes can be suppressed to some extent by ribs installed perpendicular to the rotation direction of the food.

[0006] The applicant has proposed a mixer (inclined mixer 10) in which the rotation axis of the cooking utensil rotates not in a vertical plane but at an angle to the vertical. In this inclined mixer 10, the food rotates in the cooking cup 30 in an inclined plane inclined to the vertical axis, i.e., in a direction that includes a vertical component (see arrows R1 and R2 in Figures 23(a) and 23(b)).

[0007] 24 is a view from a different angle of the flow of ingredients in the cooking cup 30 of the inclined mixer 10. As shown by the arrow in the figure, the ingredients flow diagonally upward from the bottom of the cup 40 toward the lid 50.

[0008] For this inclined mixer 10, as shown in FIG. 25(b), a single intake / exhaust hole 72c was formed near the center of the lid 50, and the outer periphery of the intake / exhaust hole 72c was surrounded by a rib 78b. The flow of the food around the lid 50 was observed. The results showed that, although it varied depending on the volume and viscosity of the food, the flow of the food contacting the lid 50 changed as indicated by arrow R5 in the figure. It was also found that when the food 90 moved upward due to stirring and the air in the cooking cup 30 was exhausted, the food leaked out through the single intake / exhaust hole 72c of the lid 50. The exhaust air passing through the intake / exhaust hole 72c had a stronger force than the intake air, and the leaked food sometimes did not return to the cup 40 and instead accumulated inside the lid 50. Therefore, particularly in the inclined mixer 10, if there is only one intake and exhaust hole 72c, even if the rib 78b is provided, leakage of the food cannot be sufficiently prevented, and the food may block the intake and exhaust hole 72c.

[0009] An object of the present invention is to provide a cooker that can effectively prevent the food from blocking the intake and exhaust holes in the lid of the cooking cup. [Means for solving the problem]

[0010] The cooking appliance according to the present invention comprises: a cooking cup including a cup and a lid that closes an upper opening of the cup; A cooking utensil that rotates within the cup and stirs the food being cooked; A cooking appliance comprising: The lid body has a lid plate with an exhaust hole and an intake hole extending from the inner surface of the lid plate, which is the lower surface exposed inside the cup, to the top surface of the lid plate, which is the upper surface.

[0011] It is desirable that the intake hole be located downstream of the exhaust hole in the direction of flow of the food being swirled by the cooking implement.

[0012] The top surface of the cover plate may have an inclined surface that slopes downward toward the air intake hole.

[0013] The top surface of the cover plate may be configured to have a protruding leakage prevention wall surrounding the exhaust hole and the intake hole.

[0014] The cover plate may have a protruding baffle wall on the inner surface thereof surrounding the intake hole and the exhaust hole, and the baffle wall may have a drain formed therein.

[0015] The inner surface of the cover plate may be configured such that a backflow prevention wall projects downstream of the baffle wall in the direction of flow of the food swirling around the cooking implement.

[0016] The cooking tool may be configured such that the rotation axis is inclined relative to the vertical direction. [Effects of the Invention]

[0017] According to the cooking appliance of the present invention, by providing the intake and exhaust holes in the lid as described above, the flow of intake and exhaust air can be restricted to one direction, preventing the food from leaking out to the lid side and preventing the intake and exhaust holes from becoming clogged.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The cooking appliance of the present invention will be described with reference to the drawings. In this embodiment, a mixer 10 is used as an example of the cooking appliance, but the cooking appliance is not limited to the mixer 10 and may be, for example, a food processor, a juicer, a mill, a blender, or the like, as long as it rotates the cooking appliance to cook ingredients.

[0020] FIG. 1 shows the overall configuration of a mixer 10 according to one embodiment of the present invention. FIG. 2 is a perspective view of a cooking cup 30, and FIG. 3 is a side view of the cooking cup 30. Note that the right side of FIG. 1 will be referred to as the front side and the left side as the rear side, as appropriate. As shown in FIG. 1, the mixer 10 comprises a main body 20 and a cooking cup 30 attached to the top of the main body 20. In the mixer 10 of this embodiment, the cooking cup is not attached vertically to the main body, but is attached and detached to and from the main body 20 by moving the cooking cup toward and away from the main body 20 at an angle non-vertical to the main body 20 (for example, horizontally or at an angle of 75° or less relative to the horizontal), as shown by arrow L in FIG. 1.

[0021] The main body 20 comprises a horizontal section 21 extending substantially parallel to the installation surface, and a vertical section 22 extending upward from the rear of the horizontal section 21 to substantially the same height as the cooking cup 30. Although not shown, the horizontal section 21 and the vertical section 22 are configured to fit the rear end of the cooking cup 30 and position it without wobbling. Also, as shown in FIG. 1, a main body side coupling 23 to which the cooking utensil 44 of the cooking cup 30 is connected is provided inside the horizontal section 21. The main body side coupling 23 is connected to the output shaft 25 of the motor 24 and is rotatable by the motor 24, which is driven by a commercial power source.

[0022] A control unit (not shown) is provided in an appropriate position on the main body 20, and the motor 24 is turned on and off by a switch 26 electrically connected to the control unit. In the illustration, the switch 26 is located at the front end of the horizontal portion 21.

[0023] 2 and 3, cooking cup 30 has cup 40 into which ingredients are poured and lid 50 that closes the top opening of cup 40, with handle 41 formed on the front side of cup 40. Cup 40 is a cylindrical body that extends vertically above approximately the center, and has bent portion 42 that is bent diagonally downward and rearward toward horizontal portion 21 of main body 20 at its lower end.

[0024] As shown in Figure 1, a cutter die 43 with a circular cross section is attached to the bent portion 42 side of the cup 40. The cutter die 43 is a rotatable cooking utensil 44 having blades and cutters suited to the cooking contents. The cooking utensil 44 is connected to a rotating shaft 45 that rotatably passes through the cutter die 43, and a cooking utensil-side coupling 46 is disposed at the base end of the rotating shaft 45, as shown in Figures 1 and 2. When the cooking cup 30 is attached to the main body 20, the cooking utensil-side coupling 46 engages with the main body-side coupling 23 described above, allowing them to rotate together (Figure 1).

[0025] Fig. 4 is a cross-sectional view taken along line AA in Fig. 3, Fig. 5 is a cross-sectional view taken along line BB in Fig. 3, and Figs. 6 to 11 show the lid body 50 removed from the cup 40. In this embodiment, the lid body 50 is composed of a lid main body 60 that forms the underside of the lid body 50 (the cup 40 side), and a lid cover 80 that covers the upper surface of the lid main body 60. Also, Figs. 12 to 22 show the lid main body 60 with the lid cover 80 removed.

[0026] In a specific embodiment, the lid body 60 has a configuration in which the upper side of a cylindrical portion 61, the diameter of which is slightly reduced on the lower side, is covered with a lid cover 80. A lid plate 70 is formed on the inside of the cylindrical portion 61. The detailed configuration of the lid plate 70 will be described later, but the lid plate 70 has one exhaust hole 72a and one intake hole 72b that communicate between the inside of the cup 40 and the outside. The exhaust hole 72a is a hole through which air mainly flows from the cup 40 to the outside via the lid body 60, and the intake hole 72b is a hole through which air mainly flows from the outside into the cup 40 via the lid body 60. Note that the shape of the lid body 60 other than the lid plate 70 portion is not limited to that described above or shown in the figures.

[0027] As shown in Figures 4 and 5, the lower side of the cylindrical portion 61 is shaped to fit into the inner surface of the upper edge of the cup 40. Furthermore, as shown in Figures 7 and 8, the upper edge of the cylindrical portion 61 has outwardly bulging engagement portions 62, 63 formed on the front and rear ends, respectively. The lid cover 80 has outwardly protruding engagement receiving portions 81, 82 into which the engagement portions 62, 63 fit. The lid body 60 is attached to the lid cover 80 by fitting the engagement portions 62, 63 into the engagement receiving portions 81, 82 of the lid cover 80. In this embodiment, the engagement receiving portion 81 on the front side of the lid cover 80 also serves as an operating piece that the user rotates to attach or detach the lid body 50 to or from the cup 40.

[0028] Thus, as described above, the lid body 50 is integrated by fitting the lid cover 80 to the lid main body 60. When using the lid body 50, the cylindrical portion 61 of the lid main body 60 is fitted into the cup 40, and the operating piece 81 of the lid body 50 is pushed clockwise when viewed from above so that it overlaps with the handle 41 of the cup 40, as shown in FIG. 2. This engages the cup 40 and the lid body 50, and the lid body 50 is attached to the cup 40 without coming off. Furthermore, when the operating piece 81 is pushed counterclockwise, the lid body 50 is removed from the cup 40.

[0029] The cooking cup 30 is attached to the main body 20 by placing ingredients in the cup 40, attaching the lid 50, and pushing it in the direction indicated by arrow L in FIG. 1 . The rear engagement portion 82 of the lid cover 80 doubles as a positioning portion that fits into a positioning portion of the main body 20 (not shown) when attaching the cooking cup 30 to the main body 20, ensuring that the cooking cup 30 is attached in the correct position relative to the main body 20. As shown in FIG. 1 , attaching the cooking cup 30 to the main body 20 connects the couplings 23, 46 of the main body 20 and the cooking cup 30. Operating the switch 26 drives the motor 24, causing the cooking utensil 44 to rotate (clockwise in this embodiment), stirring and cooking the ingredients, and producing the food. FIGS. 23 and 24 are schematic diagrams showing the rotation of the food 90 when the cooking utensil 44 is rotated. As shown in the figure, in this invention, the rotation axis 45 of the cooking utensil 44 is inclined relative to the vertical, so the food 90 rotates clockwise within the inclined plane. Arrow R1 in FIG. 23(a) indicates the swirling direction of the food 90 when a low-viscosity food 90 or the cooking utensil 44 is rotated at a low speed, while arrow R2 in FIG. 23(b) indicates the swirling direction of the food 90 when a high-viscosity food or the cooking utensil 44 is rotated at a high speed. FIG. 24 is a perspective view of the flow of the food 90 in FIGS. 23(a) and 23(b) as seen from the rear side of the cooking cup 30. The food 90 flows upward along the inner surface of the cup 40, as indicated by arrow R4. Note that FIG. 23(c) indicates the swirling direction (arrow R3) of the food 90 generated in a mixer (referred to as a "vertical mixer 11") in which the rotation axis 45 of the cooking utensil 44 is vertical, and the food 90 rotates R3 within a substantially horizontal plane.

[0030] By rotating cooking utensil 44, a vortex-shaped air layer 91 is formed in the center of food 90, with its lower end substantially coinciding with the center of rotation of cooking utensil 44. In the case of FIG. 23(a), this air layer 91 is slightly tilted forward, while in the case of FIG. 23(b), the inclination is greater, reaching the inner surface of the front end of cup 40. That is, near lid 50, air layer 91 with less food 90 is formed diagonally forward of cooking utensil 44. In vertical mixer 11, vortex-shaped air layer 91 is generated in a substantially vertical direction.

[0031] As shown in Figures 23(a), (b), and 24, the mixer 10 of this embodiment is an inclined mixer in which the swirling directions R1 and R2 of the food 90 are inclined, so the food 90 becomes a swirling flow that includes not only horizontal but also vertical components, and can be mixed evenly and more effectively and cooked.

[0032] At this time, lid 50 is attached airtight to cup 40. If the lid is completely airtight, negative or positive pressure will be created inside cup 40 when attaching or removing lid 50 from cup 40, making it impossible to attach or remove lid 50. Furthermore, the air pressure inside cooking cup 30 changes due to cooking processes such as stirring, or changes in the temperature of the food being cooked. If negative pressure is created inside cooking cup 30, lid 50 cannot be removed, and if positive pressure is created inside cooking cup 30, there is a risk of food splashing out when lid 50 is opened. Therefore, suction and exhaust holes are formed in lid plate 70 of lid 50 to adjust the air pressure inside cup 40.

[0033] In the present invention, the holes for intake and exhaust are divided into exhaust hole 72a and intake hole 72b, one each formed in lid plate 70. In a specific embodiment, they are formed in lid plate 70. Exhaust hole 72a and intake hole 72b penetrate from lid plate inner surface 73 exposed inside cup 40 to lid plate top surface 74 on the lid cover 80 side, which is the upper surface.

[0034] It is preferable that the exhaust hole 72a and the intake hole 72b have the same diameter, but the exhaust hole 72a and the intake hole 72b may have different sizes. If the diameters of the exhaust hole 72a and the intake hole 72b are too small, the food 90 will easily stick to them due to tension and become blocked. On the other hand, if the diameters of the exhaust hole 72a and the intake hole 72b are too large, the sound of the food 90 being stirred in the cooking cup 30 will leak out through the holes 72a and 72b and become noisy. For this reason, it is desirable that the diameters of the exhaust hole 72a and the intake hole 72b be 2 mm to 5 mm.

[0035] As shown in Figure 8 etc., it is desirable to provide exhaust hole 72a and intake hole 72b not in the center of cover plate 70 but on the front side facing operation piece 81, specifically diagonally forward of cooking utensil 44. The position where vortex air layer 91 shown in Figures 23(a) and (b) is formed is where food 90 flows less than at the rear side or peripheral surface, so providing exhaust hole 72a and intake hole 72b at the position where air layer 91 is formed prevents food 90 from leaking out.

[0036] 8 and other figures, exhaust hole 72a and intake hole 72b are preferably provided closer to center O of cover plate 70. Since the swirling food rotates faster on the outer periphery of cup 40 than on the inner periphery, by providing exhaust hole 72a and intake hole 72b closer to the center where food 90 rotates relatively slowly, the amount of food that enters exhaust hole 72a and intake hole 72b can be reduced.

[0037] 13, it is desirable to form exhaust hole 72a and intake hole 72b so that intake hole 72b is located downstream of exhaust hole 72a, i.e., exhaust hole 72a is located upstream of intake hole 72b, with respect to the flow direction R of food 90. This results in a one-way air flow in which air inside cooking cup 30 is exhausted from exhaust hole 72a on the upstream side and air flows into cooking cup 30 from intake hole 72b on the downstream side, preventing exhaust hole 72a and intake hole 72b from being blocked by food 90.

[0038] In addition, the shape of the lid plate 70 is as follows so that exhaust can be efficiently performed through the exhaust hole 72a and air can be efficiently taken in through the intake hole 72b, and so that even if the food 90 leaks out onto the top surface 74 of the lid plate, the food 90 can be efficiently returned into the cooking cup 30.

[0039] First, regarding the lid plate top surface 74, when air is exhausted from the exhaust hole 72a, some of the food 90 may leak out through the exhaust hole 72a and onto the lid plate top surface 74 side. To efficiently return the leaked food 90 into the cooking cup 30, the lid plate top surface 74 side is provided with an inclined surface 75 that slopes downward toward the intake hole 72b, as shown in FIGS. 11, 15, and 18. The inclined surface 75 slopes downward in the direction of arrow P. The inclined surface 75 is preferably formed so that the intake hole 72b is lower than the exhaust hole 72a. This allows the food 90 leaking out from the exhaust hole 72a to flow along the inclined surface 75 toward the intake hole 72b without remaining near the exhaust hole 72a. Therefore, the exhaust hole 72a is not blocked by the food 90, and the food 90 accumulated in the cooking cup 30 is returned through the intake hole 72b during intake.

[0040] Furthermore, a leakage prevention wall 76 is formed on the top surface 74 of the lid plate to surround the exhaust hole 72a, the intake hole 72b, and the inclined surface so that the food 90 leaking through the exhaust hole 72a does not spread over the top surface 74 of the lid plate. In Figures 11, 12, 15, etc., the leakage prevention wall 76 is a rib that surrounds the exhaust hole 72a, the intake hole 72b, and the inclined surface 75. To prevent the food 90 from leaking beyond the leakage prevention wall 76, as shown in Figure 11, it is desirable to narrow the gap CL between the upper edge of the leakage prevention wall 76 and the underside of the lid cover 80 so that gas can flow through the gap CL but the food 90, which is a liquid, cannot pass through the gap CL.

[0041] As shown in FIGS. 13 to 18, the inner surface 73 of the lid plate has a guide surface 77 that slopes downward toward the downstream side of the rotation direction R (see FIG. 13) of the food 90 to prevent the food 90 from approaching the exhaust hole 72a and the intake hole 72b along the inner surface 73 of the lid plate within the cooking cup 30. The guide surface 77 can be formed to form a central angle of approximately 45 to 120° with respect to the center O of the lid plate 70. More preferably, the guide surface 77 can be formed in the shape of a fan having a center offset from the center O of the lid plate 70, as shown in FIG. 15.

[0042] By providing guide surface 77, part of the flow of food 90 generated in cup 40 hits lid body 50, and flows down guide surface 77 as shown by arrow S in Fig. 18 (also shown in Figs. 4 and 6), becoming a diagonally downward flow away from lid plate inner surface 73. This prevents food 90 from approaching exhaust hole 72a and intake hole 72b, thereby preventing food 90 from leaking out of exhaust hole 72a.

[0043] Furthermore, as shown in FIGS. 13 to 15 , the inner surface 73 of the lid plate has protruding baffle walls 78 around the exhaust hole 72a and the intake hole 72b. The baffle walls 78 are ribbed in the illustration and block the flow of food 90 approaching the exhaust hole 72a and the intake hole 72b from various directions, as indicated by arrows R5 in FIG. 25(a). To prevent water from pooling inside the baffle walls 78 during cleaning or other maintenance of the lid 50, it is desirable to form a drain 78a on at least a portion of the baffle walls 78. For example, in FIG. 13 , the baffle walls 78 are U-shaped rather than completely surrounding the exhaust hole 72a and the intake hole 72b, with some portions lacking ribs. This prevents water from pooling inside the baffle walls 78 and improves ease of maintenance. The drain 78a may be formed by cutting out a portion of the baffle walls 78.

[0044] 13, 14, and 18, a backflow prevention wall 79 is provided downstream of the baffle wall 78 (arrow R in FIG. 13 indicates the flow direction of the food 90) to prevent the food 90 from flowing back toward the exhaust hole 72a or the intake hole 72b. The backflow prevention wall 79 can be configured to branch off from the baffle wall 78. This allows the food 90 to be prevented from entering the exhaust hole 72a or the intake hole 72b even if a backflow occurs in the food 90 as shown in FIG. 25(a), as the food 90 collides with the backflow prevention wall 79.

[0045] In the present invention, the exhaust hole 72a and the intake hole 72b are formed in the lid 50 of the tilt-type mixer 10, which is a cooking appliance, as described above. In addition, the shape of the lid plate 70 is devised. This allows the air to flow in one direction as described above, and can effectively prevent the food 90 from blocking the exhaust hole 72a and the intake hole 72b, thereby achieving the various effects described above.

[0046] The above description is for the purpose of explaining the present invention, and should not be construed as limiting the invention described in the claims or narrowing its scope. Furthermore, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications are possible within the technical scope described in the claims.

[0047] For example, in this embodiment, an inclined mixer 10 in which the rotation axis 45 of the cooking tool 44 is inclined has been described, but the present invention can also be applied to an upright mixer 11 in which the rotation axis 45 of the cooking tool 44 is vertical.
