Description

The present invention relates to a cooking device equipped with a rotating cooking tool like a food processor, and more specifically, to a cooking device in which the cooking tool is a grater cutter.

In cooking appliances such as food processors, the rotating cooking tool chops, grates, crushes, chops, or mixes ingredients. The type of cooking is determined by the cooking tool, and when grating ingredients such as radishes or carrots, a grater cutter with a grater blade on the top rotates, and the ingredients are cut against the grater blade and grated into fine pieces.

Japanese Patent Application Laid-Open No. 10-85140

The grater is attached to the cooking utensil attachment part. In Patent Document 1, the cooking utensil attachment part is connected to the motor via a reduction mechanism such as a belt or pulley. The use of a reduction mechanism leads to a more complex device configuration, larger size, and higher noise levels, so there is a demand for a direct-drive cooker in which the cooking utensil attachment part is directly driven by the motor. However, a direct drive cannot rotate the cooking utensil attachment part at high speeds, so the rotation speed of the grater cutter is also low. As a result, the food sticks to the grater cutter and rotates together with it, which can prevent the food from being grated properly.

The object of the present invention is to provide a cooking device such as a food processor that can prevent ingredients from sticking to the grater.

The cooking device according to the present invention comprises:
A cooking utensil attachment part that rotates by a motor;
A cooking utensil attached to the cooking utensil attachment portion;
A cooking device comprising:
The cooking utensil is attached to the cooking utensil attachment portion with a first play in the circumferential direction.

Moreover, the cooking device according to the present invention is
A cooking utensil attachment part that rotates by a motor;
A cooking utensil attached to the cooking utensil attachment portion;
A cooking device comprising:
The cooking utensil is attached to the cooking utensil attachment portion with a second play in the radial direction and is tiltable relative to the cooking utensil attachment portion.

It is desirable that the cooking utensil is formed with a friction portion that abuts against the cooking utensil attachment portion when tilted relative to the cooking utensil attachment portion to prevent the cooking utensil from tilting more than a predetermined angle.

The cooking utensil can be a grater cutter having a disk-shaped grater blade plate with multiple grater blades formed on the upper surface.

It is desirable that the upper surface of the grater blade plate has a gradient that increases from the center of rotation toward the outside in the radial direction.

The upper surface of the grater blade plate is formed with multiple grater blade rows, with the grater blades arranged radially outward from the center of rotation, and it is desirable that adjacent grater blade rows are formed in positions where the grater blades do not overlap in the radial direction.

It is desirable that the grater blade plate be adjacent to the upstream side of the row of grater blades in the direction of rotation and have a slit that penetrates from top to bottom.

It is desirable that one or more ribs be formed facing downward on the peripheral surface of the grater blade plate.

According to the cooking device of the present invention, the cooking utensil is attached to the cooking utensil attachment part with a first play in the circumferential direction. Therefore, even if the motor is driven and the cooking utensil attachment part rotates, the cooking utensil remains stationary at first without being driven by the cooking utensil attachment part, and starts to rotate with a delay of the first play. In other words, when the cooking utensil starts to rotate, the cooking utensil attachment part has already started to rotate at a certain speed or more, so when the cooking utensil rotates driven by the cooking utensil attachment part, the cooking utensil hits the cooking utensil attachment part and receives an impact. Due to the reaction, the food placed on the cooking utensil is peeled off from the cooking utensil even if it was stuck to the cooking utensil when it was stationary. This makes it possible to prevent the food from rotating together with the cooking utensil while stuck to it, and cooking can be performed efficiently. Also, when the motor is stopped, the cooking utensil stops with a delay of the first play from the cooking utensil attachment part, so it hits the cooking utensil attachment part, which stopped rotating first, and receives an impact. The reaction force causes the food to peel off from the cooking utensil, effectively preventing the food from sticking to the utensil.

Furthermore, according to the cooking device of the present invention, the cooking utensil is attached to the cooking utensil attachment part with a second radial play. In other words, the cooking utensil is supported so that it can tilt relative to the cooking utensil attachment part. Therefore, if food is placed unevenly on the cooking utensil, the weight of the food causes the cooking utensil to tilt and rotate while swinging. This makes it easier for food on the cooking utensil to peel off from the cooking utensil, prevents the food from sticking to the cooking utensil, and allows for efficient cooking.

The cooking device of the present invention will be described with reference to the drawings. In the following, a food processor 10 will be used as an example of the cooking device, and a grater cutter 60 will be used as an example of the cooking utensil. However, the cooking device is not limited to the food processor 10 as long as it rotates the cooking utensil to cook ingredients. The cooking utensil is also not limited to the grater cutter 60.

Figure 1 is an external perspective view showing the overall configuration of a food processor 10 according to one embodiment of the present invention, and Figure 2 is a cross-sectional view taken along line II-II in Figure 1 and seen in the direction of the arrow.

As shown in FIG. 1, the food processor 10 is generally configured by placing a cooking cup 30, into which ingredients are put, on the top of the main body 20. The cooking cup 30 has a handle 34, and the top can be covered with a lid 40. As shown in FIG. 2, a motor 21 is provided inside the main body 20, and a rotating shaft 22 of the motor 21 protrudes upward from the main body 20. A shaft cover 23, generally made of resin, is attached to the tip of the rotating shaft 22, and a cooking utensil attachment part 50 can be attached and detached to the shaft cover 23 by screwing or the like. The cooking utensil attachment part 50 is attached to the shaft cover 23 with the cooking cup 30 attached to the main body 20. Similarly, a grater cutter 60, which serves as a cooking utensil, is attached to the cooking utensil attachment part 50 so as to be rotatable together with the cooking utensil attachment part 50 with the cooking cup 30 placed on the main body 20. In the figure, the motor 21 rotates the cooking utensil attachment part 50 using a direct drive, but the rotating shaft 22 and cooking utensil attachment part 50 may be connected via a reduction mechanism.

As shown in FIG. 2, the main body 20 is provided with a switch 24 for the motor 21 on the handle 34 side of the cooking cup 30, and the switch 24 is operated by pressing an operating element 33 built into the peripheral surface of the cooking cup 30 by pressing the lid 40. The motor 21 is energized by operating the switch 24, causing the rotating shaft 22 to rotate clockwise. Note that the method of operating the motor 21 is not limited to this embodiment.

As described above, the rotating shaft 22 protrudes upward from the main body 20, and a shaft cover 23 that can rotate together with the rotating shaft 22 is attached to the tip. The shaft cover 23 has a length that passes through a cylindrical shaft tube 31 provided in the cooking cup 30. The outer periphery of the shaft cover 23 is threaded as shown in FIG. 2, and a cooking utensil attachment part 50 for attaching a grater cutter 60 is screwed into it.

The cooking cup 30 is a container that is open at the top and into which ingredients are placed to cook. The illustrated cooking cup 30 is generally cylindrical with a bottom, and has a cylindrical shaft tube 31 protruding upward from the bottom in the center. The top opening of the cooking cup 30 is closed by a lid 40.

As shown in FIG. 1, the cooking cup 30 has a semi-cylindrical protrusion 32 with a certain thickness formed vertically on its periphery, and a handle 34 for the user to grasp is provided on the outer periphery of the protrusion 32. Inside the protrusion 32, as shown in FIG. 2, the above-mentioned operating element 33 is arranged so as to be able to slide while being biased upward. The upper end of the operating element 33 abuts against an operating protrusion 41 formed on the covering lid 40, and by pressing the lid 40 on the handle 34 side downward, the operating protrusion 41 pushes the operating element 33 downward, and the switch 24 is operated.

In the cooking cup 30, with the cooking cup 30 placed on the main body 20 in advance, the cooking utensil attachment part 50 is attached to the shaft cover 23 protruding from inside the shaft tube 31. As shown in FIG. 2, the cooking utensil attachment part 50 has an inner tube part 51 with a thread cut on the inner surface to screw into the shaft cover 23. As shown in FIGS. 2 to 8, the cooking utensil attachment part 50 has an umbrella part 52 that expands diagonally downward from the upper end of the inner tube part 51 and has a cylindrical tip extending downward. The umbrella part 52 covers the shaft tube 31 of the cooking cup 30 and prevents food from entering the shaft tube 31. The lower edge of the umbrella part 52 is formed with a flange 55 protruding toward the outer periphery.

As shown in Figs. 2 to 4, the umbrella portion 52 of the cooking utensil attachment portion 50 has a plurality of attachment ribs 53 formed on the circumferential surface of the cylindrical portion. The attachment ribs 53 are ribs that engage with the attachment recesses 63 of the grater cutter 60 and rotate the grater cutter 60 together with the cooking utensil attachment portion 50. In the illustrated embodiment, the attachment ribs 53 are elongated protrusions and can be formed at equal intervals on the circumferential surface of the umbrella portion 52. As shown in the enlarged view A of the circled portion in Fig. 3, the dimensions of the attachment ribs 53 are a width w and a height (radial direction) h from the cylindrical outer periphery of the umbrella portion 52, and are designed to fit into the attachment recesses 63 of the grater blade plate 61 described later with play in the circumferential and/or radial directions (C1, C2: see the enlarged view C of the circled portion in Fig. 4). The number of attachment ribs 53 can be the same as the number of attachment recesses 63 of the grater cutter 60 described later, or a number less than the number of the attachment recesses 63, preferably a number approximately equal to the number of the attachment recesses 63. Details such as the size and number of mounting ribs 53 will be described later.

A cooking utensil is attached to the cooking utensil attachment portion 50. In this embodiment, the cooking utensil is a grater cutter 60. As shown in Figures 2 to 8, the grater cutter 60 has multiple grater blades 66 formed on the upper surface of a disk-shaped grater blade plate 61. The grater blade plate 61 rotates to cut ingredients placed on the upper surface against the grater blades 66, thus grating them into fine pieces.

The grater blade plate 61 has a mounting hole 62 in the center through which the umbrella portion 52 of the cooking utensil attachment portion 50 passes. The inner surface of the mounting hole 62 has multiple mounting recesses 63 into which the mounting ribs 53 of the cooking utensil attachment portion 50 fit. As shown in the enlarged view B of the circled area in Figure 3, the mounting recesses 63 can be formed from a recess that widens diagonally downward (hereinafter referred to as a guide recess 65) and a parallel recess (hereinafter referred to as a support recess 64) above approximately the center.

As shown in the enlarged view B of the circled portion in FIG. 3 and the enlarged view C of the circled portion in FIG. 4, the support recess 64 is formed so that its width W is greater than the width w of the mounting rib 53. The difference between these (W-w) is C1 (hereinafter referred to as the "first play"). The details of the first play C1 will be described later, but the sum of the left and right play of the support recess 64 and the mounting rib 53 in the enlarged view C of the circled portion is C1.

The guide recess 65 is a recess for smoothly guiding the mounting rib 53 into the support recess 64 when attaching the grater blade plate 61 to the cooking utensil attachment part 50. It is desirable to form the guide recess 65 wider than the width W of the support recess 64.

The mounting recess 63 (support recess 64 and guide recess 65) is formed so that its depth H (radial direction: where H is the dimension from the cylindrical outer periphery of the umbrella portion 52, which is the same as the height of the mounting rib 53) shown in the enlarged view B of the circled portion in Fig. 3 is greater than the height h of the mounting rib 53 shown in the enlarged view A of the circled portion, and the difference (H-h: see the circled portion C in Fig. 4) is C2 (hereinafter referred to as the "second play"). The details of the second play C2 will be described later, but the second play C2 allows the grater cutter 60 to be supported so that it can tilt relative to the cooking utensil mounting portion 50. As a result, as described below, the grater cutter 60 can rotate while swinging, preventing food from sticking, but to prevent the grater cutter 60 from tilting beyond a certain angle, as shown in Figures 10 and 11 described below, when the grater cutter 60 tilts at a certain angle, the mounting hole 62 of the grater cutter 60 rubs against the umbrella part 52 of the cooking utensil mounting part 50 to prevent it from tilting any further. For example, in Figure 10, the circumferential surface of the mounting rib 53 (particularly the upper and lower edge sides of the mounting rib 53) forms a rubbing part (circled part 54 in the figure) that rubs against the mounting recess 63, and in Figure 11, a flange 55 is formed at the lower end of the umbrella part 52, and the flange 55 forms a rubbing part that rubs against the mounting recess 63.

In the illustrated embodiment, the grater cutter 60 has a grater blade plate 61 with an inverted umbrella-like slope that rises radially outward from the mounting hole 62, which is the center of rotation.

The grater blade plate 61 can also be configured to have a grater blade row 67 on the top surface of which a number of grater blades 66 are formed radially outward from the mounting hole 62. As shown in FIG. 4, the grater blades 66, 66a of adjacent grater blade rows 67, 67a are spaced apart so that the grater blades 66, 66a adjacent in the circumferential direction do not overlap in the radial direction, as indicated by the reference characters L1 and L2. Specifically, as shown in FIG. 12, the spacing p between the grater blades 66, 66 adjacent in the radial direction is the same as the width P of the grater blade 66 (66a), and the grater blades 66, 66a of adjacent grater blade rows 67, 67a are formed so that they do not overlap in the radial direction.

The grater blade plate 61 can have multiple slits extending radially outward from the mounting hole 62. The slits basically serve to allow the grated ingredients to pass through and drop into the bottom of the cooking cup 30. For example, as shown in FIG. 4, there can be two types of slits 68, 68a. One type is a slit 68 formed close to the upstream side of the grater blade row 67 in the rotation direction, as shown in an enlarged view in FIG. 13 described later, and the other type is a slit 68a formed at approximately the middle position of the grater blade row 67.

Furthermore, as shown in Figs. 3, 5, etc., multiple downward protrusions are formed on the periphery of the grater blade plate 61. These protrusions are scraping ribs 69, which push the grated food downwards in the cooking cup 30 as grating cooking continues, and prevent the grated food inside the cooking cup 30 from climbing up the side of the cooking cup 30. As shown in Fig. 5, the scraping ribs 69 are inclined so that the tip on the rotation direction side (clockwise) of the grater cutter 60 faces downstream in the rotation direction, so that the grated food can be effectively pushed down toward the bottom side of the cooking cup 30.

Then, for the food processor 10 configured as above, the cooking cup 30 is placed on the main body 20 as shown in Figures 1 and 2. The cooking cup 30 is attached by setting the shaft cover 23 extending upward from the main body 20 so that it passes through the shaft tube 31 as shown in Figure 2, and screwing the cooking utensil attachment part 50 into the shaft cover 23.

Next, the grater cutter 60 is attached to the cooking utensil attachment part 50. As shown in Figs. 2 to 8, the grater cutter 60 can be attached by passing the attachment hole 62 through the umbrella part 52 of the cooking utensil attachment part 50 and fitting the attachment recess 63 into the attachment rib 53. That is, to attach the grater cutter 60, it is necessary to vertically align the attachment recess 63 and the attachment rib 53. If these positions are not aligned, the grater cutter 60 can be rotated in a horizontal plane while being placed against the cooking utensil attachment part 50, but if the number of attachment recesses 63 and attachment ribs 53 is small, the rotation angle becomes large and alignment takes time. On the other hand, the rotation angle can be reduced by arranging many attachment recesses 63 and attachment ribs 53 at small intervals, but since the food processor 10 is a device for cooking ingredients, if there are many protrusions and recesses, cleaning takes time. Therefore, it is required to reduce the rotation angle of the grater cutter 60 for alignment while reducing the number of protrusions and recesses.

In this embodiment, the mounting recess 63 is provided with a wide guide recess 65 that guides the mounting rib 53 into the support recess 64, as shown in the enlarged view B of FIG. 3. By providing the guide recess 65, if the positions of the wide guide recess 65 and the mounting rib 53 are aligned, the weight of the grater cutter 60 guides the mounting rib 53 into the support recess 64 along the slope of the guide recess 65, and the mounting rib 53 fits into the support recess 64. On the other hand, even if the positions of the guide recess 65 and the mounting rib 53 are not aligned, the width of the guide recess 65 is made wide, so that the rotation angle of the grater cutter 60 in the horizontal plane can be reduced to align them, making it easier to attach the grater cutter 60 to the cooking utensil attachment part 50.

The number of mounting ribs 53 can be the same as the number of mounting recesses 63, but in this embodiment, the number of mounting ribs 53 is reduced by making the number of mounting ribs 53 a multiple of the number of mounting recesses 63. In the illustrated embodiment, six mounting ribs 53 are provided every 60°, while twelve mounting recesses 63 are provided every 30°. By providing a multiple of the number of mounting recesses 63, when attaching the grater cutter 60 to the cooking utensil attachment part 50, the rotation angle of the grater cutter 60 in the horizontal plane is less than half the interval between the mounting recesses 63, that is, in this embodiment, the mounting recesses 63 can be attached to the mounting ribs 53 by simply rotating the grater cutter 60 by a maximum of 30°. Note that it is desirable to provide at least four mounting ribs 53 and mounting recesses 63 at intervals of 90° or less in order to maintain balance when rotating the grater cutter 60.

As shown in FIG. 2 etc., after the grater cutter 60 is attached to the cooking utensil attachment part 50, the food to be grated (not shown) is placed in the cooking cup 30 and the lid 40 is closed. Then, by pushing the lid 40 downward, the switch 24 is operated and the motor 21 rotates. The rotation of the motor 21 is directly transmitted to the shaft cover 23, causing the cooking utensil attachment part 50 to rotate.

The grater cutter 60 rotates integrally with the cooking utensil attachment part 50 as the attachment rib 53 of the cooking utensil attachment part 50 comes into contact with the inner surface of the support recess 64 of the attachment recess 63. The grater cutter 60 has numerous grater blades 66 formed on the upper surface of the grater blade plate 61, so ingredients may not be cut by the grater blades 66 and may get caught on the grater blades 66, or may be attracted to the grater blade plate 61 and rotate integrally while stuck to the grater blade plate 61. In particular, when a direct drive is used, the initial rotation speed and torque are small, so ingredients stuck to the grater blade plate 61 are difficult to shake off.

In this embodiment, as shown in Fig. 2 and Fig. 4 (enlarged view C), the width W of the support recess 64 is made larger than the width w of the mounting rib 53, and a first play C1 in the circumferential direction is formed between the grater cutter 60 and the cooking utensil mounting part 50 by the difference (W-w) between them. As a result, when the cooking utensil mounting part 50 starts to rotate, the grater cutter 60 initially has the first play C1 and remains stationary without being moved by the cooking utensil mounting part 50. As the cooking utensil mounting part 50 rotates (arrow R), the first play C1 disappears, and as shown in Fig. 9, when the support recess 64 hits the mounting rib 53, the grater cutter 60 starts to rotate together with the cooking utensil mounting part 50. At this time, the grater cutter 60 receives an impact when the mounting rib 53 hits the inner surface (upstream side in the direction of rotation) of the support recess 64, and the food on the grater blade plate 61 is peeled off from the grater blade plate 61 due to the reaction, even if it was stuck to the grater blade plate 61 when it was stationary. This allows the food to be cut by the rotating grater blade 66 and grated into fine pieces. The first play C1 is thus formed to be large enough that the grater cutter 60 receives an impact and the food comes off.

By providing the first play C1, even when the motor 21 is stopped, the grater cutter 60 stops later than the cooking utensil attachment part 50 by the first play C1, so the inner surface of the support recess 64 (downstream side in the direction of rotation) hits and receives an impact on the attachment rib 53 of the cooking utensil attachment part 50, which has stopped rotating first. Then, due to the reaction, the food is peeled off from the grater blade plate 61 and the grater blade 66, preventing the food or grated grater from sticking to the grater cutter 60.

In this embodiment, as shown in the enlarged view C of FIG. 4, the depth H of the mounting recess 63 is made larger than the height h of the mounting rib 53, and the difference (H-h) between them forms a second radial play C2 between the grater cutter 60 and the cooking utensil mounting part 50. This allows the grater cutter 60 to tilt relative to the cooking utensil mounting part 50 as shown in FIG. 10 and FIG. 11. As a result, when the food is unevenly placed on the grater blade plate 61 and an uneven load is applied as shown by the arrows X and XI in FIG. 4, FIG. 10 and FIG. 11, the grater cutter 60 tilts so that the load side moves downward due to the load, and rotates while swinging (arrow F in the figure). As a result, the food peels off from the grater blade plate 61, eliminating the sticking, and the peeled food is dispersed and the weight balance is adjusted. This allows efficient grating cooking using the grater blade 66. As shown in Figures 10 and 11, when the grater cutter 60 is tilted at a certain angle, in Figure 10, as shown by the circle, the circumferential surface of the mounting rib 53 becomes the rubbing portion 54 and rubs against the mounting recess 63, and in Figure 11, the flange 55 at the lower end of the umbrella portion 52 becomes the rubbing portion and rubs against the mounting recess 63, preventing the grater cutter 60 from tilting any further. Therefore, food does not fall off the outer circumference of the grater cutter 60, and the grater cutter 60 itself does not fall off the cooking utensil mounting portion 50.

As described above, the food is cut by the grating blades 66 of the grating cutter 60 and grated into fine pieces. As shown in FIG. 4 and described above, the grating blades 66 are formed radially on the grating blade plate 61 to form the grating blade row 67. In this embodiment, the grating blades 66, 66a of the adjacent grating blade rows 67, 67a are spaced apart at a pitch p, which is the same as the width P of the grating blade 66, as shown by symbols L1 and L2 in FIG. 4 and in the explanatory diagram 12 showing the radial formation positions of the grating blades 66, 66a, and the grating blades 66, 66 of the adjacent grating blade rows 67, 67a are formed so as not to overlap each other in the radial direction, so that each grating blade 66, 66 can efficiently cut the food 90 (FIG. 12), thereby improving efficiency.

Furthermore, the ingredients on the grater blade plate 61 may adhere to the inner surface of the cooking cup 30 due to the centrifugal force in the outer circumferential direction caused by the rotation of the grater cutter 60, making it difficult to grate and cook the ingredients properly. However, in this embodiment, as shown in FIG. 2 etc., the grater blade plate 61 has an inverted umbrella-like (cone-like) slope that rises radially outward from the mounting hole 62, which is the center of rotation, on the upper surface. As a result, part of the radial force acting on the ingredients acts in the inclined direction on the slope of the grater blade plate 61, allowing the ingredients to be cut by the grater blade 66, reducing adhesion of the ingredients to the cooking cup 30.

Then, the grated food 90 passes through the slits 68, 68a of the grater blade plate 61 as shown in FIG. 13, and falls between the outer periphery of the grater blade plate 61 and the cooking cup 30.

The grating blade plate 61 has slits 68, 68a on the radially outer side, so that the grated food 91 passes through the slits 68, 68a and falls to the bottom of the cooking cup 30. In this embodiment, the slits 68 are formed close to the upstream side of the grating blade row 67 in the rotation direction, as shown in an enlarged view in FIG. 13. The food 90 contains moisture, so a water film 92 is formed between the grating blade plate 61 and the food, and the food may be adsorbed. However, when the food heading toward the grating blade 66 passes over the slits 68 formed close to the upstream side of the grating blade row 67 in the rotation direction, the water film 92 is destroyed and the food 90 floats up, so that the grating blade 66 can efficiently grate and cook the food.

The grated food 91 that passes through the slits 68, 68a of the grater blade plate 61 moves toward the outer periphery due to centrifugal force while remaining attached to the back surface of the grater blade plate 61. Also, the grated food that passes between the outer periphery of the grater blade plate 61 and the cooking cup 30 falls down the side of the cooking cup 30. However, as the grating cooking continues, the grated food may climb up the side of the cooking cup 30. In this embodiment, a downward scraping rib 69 is formed on the outer periphery of the grater blade plate 61, and the scraping rib 69 moves along the inner surface of the cooking cup 30 as the grater cutter 60 rotates, scraping out the grated food that has adhered to it and pushing it downward, preventing the grated food from climbing up the side of the cooking cup 30.

The above explanation is for the purpose of explaining the present invention, and should not be interpreted 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.

For example, the cooking utensil is not limited to the grater cutter 60, but may be a chopping utensil with a cutting blade, a stirring utensil with a spatula, etc.
