Description

  The present invention relates to a cooking utensil for processing foodstuffs, in particular (but not in a limiting sense), nuts (nuts), beans, peas, sesame, herbs (herb), condiments (including garlic), The present invention relates to a cooking utensil and a cooking hammer for processing various foods such as cereals.

  Traditionally, when you want to break nuts such as peanuts, almonds, and walnuts (without husks) to an appropriate size, it takes time and effort with a kitchen knife, spoon, fork, etc., and broken food often jumps around. Is not practical.

  When using an old mortar and pestle, or a mortar and pestle, or Western pestle, it is difficult to break them evenly at the same time when processing a certain amount of ingredients. It took.

  A food processor that is driven by electricity can process a certain amount of food in a relatively short time, but if it is evenly processed, the food will be crushed into powder and evenly sized (granular). It was difficult to break. Also, after use, cleaning of the blade parts and the like with sticking ingredients was troublesome.

  Non-Patent Document 1 describes a cooking utensil called a spice mill for mashing spices such as pepper, sesame and herbs. Each spice mill is composed of a ceramic lid and a saucer. The lid-like part is composed of a circular dish-like part having a convexly curved bottom part and a handle part upright at the center of the upper part. The handle portion has a substantially spherical shape having a diameter that is about one third of the outer diameter of the circular dish-shaped portion. The saucer has a concave portion that is substantially matched with the curved surface of the bottom of the lid-like portion. At the time of use, the user places the spices to be processed in the recesses of the saucer, holds the lid-like handle, and grinds the spices by pressing the bottom of the lid-like part against the recesses of the saucer. According to this spice mill, since the pressing of the food to be processed is performed in a relatively wide area by the bottom surface of the lid portion and the concave surface of the saucer, a certain amount of food can be processed with a certain degree of uniformity at a time. Be expected.

  However, the spice mill described in Non-Patent Document 1 is suitable for the purpose of crushing nuts (for example, peanuts, almonds, walnuts, etc.) having a size larger than that of pepper and sesame to an appropriate size. Not. This is because, with this spice mill configuration, a general human pressing force is not sufficient to uniformly crush a plurality of hole-like nuts at once. In addition, if a lid-like portion is struck against a tray in order to apply a large force to the processed food, the ceramic parts may be broken or chipped. Furthermore, the size of the circular outer edge of the lid-like portion is substantially the same as the size of the recess of the saucer, and even from this configuration, a usage method is not assumed in which the lid-like portion is struck against the saucer.

  The present invention has been made in such a background, and the object thereof is a cooking utensil for processing a wider variety of processed foods, and more specifically, nuts (nuts), beans, and soybeans. An object of the present invention is to provide a cooking utensil and a cooking hammer suitable for performing a process of crushing or crushing various foods such as sesame, herbs (herbs), spices (including garlic), cereals and the like.

  A cooking utensil according to the present invention includes a cooking hammer made of a rigid material having impact resistance, and a cradle made of a rigid material having impact resistance, which is used together with the cooking hammer. The hammer for use includes a first flat spherical portion, a second flat spherical portion, and a constricted portion that connects the first and second flat spherical portions so that their central axes coincide with each other so as to overlap each other. And the cradle has a recess for accommodating the entire second flat spherical portion of the cooking hammer with a margin, and when the cooking hammer is placed on the recess, The first flat spherical portion has a curved bottom surface and a curved bottom surface that is in surface contact with most of the region.

  The “flat spherical portion” is a portion having a flat spherical shape formed by crushing a spherical shape along its central axis, but the portion connected to the constricted portion loses the spherical shape. The “necked portion” connects the first flat spherical portion and the second flat spherical portion, and when the user grips the first flat spherical portion with the palm as a handle portion, It has a function of providing a space in which a plurality of user's fingers and a part of a hand (for example, a ball ball) can enter. The “cradle” is a table on which a cooking hammer is placed, and a table on which food is placed and processed with the cooking hammer when the food is processed.

  With such a configuration, it is easy to strike, push, beat, and knead the processed food on the cradle, and all the ingredients on the cradle from the curved bottom surface of the cooking hammer. For example, when the ingredients are crushed, all ingredients can be crushed to the same size. In particular, in the hitting operation, the desired operation can be achieved with a relatively weak force by using the weight of the cooking hammer. Furthermore, by gripping the first flat spherical portion so as to be gripped with a palm, the operation of the cooking hammer during such operation is facilitated.

  The first flat spherical portion, the second flat spherical portion, and the constricted portion of the cooking hammer are preferably integrally formed. As a result, the seam and the joint are eliminated, and the structure is robust, and the food is easy to clean and hygienic.

  The cooking hammer can be made of metal or stone, for example.

  The outer diameter of the first flat spherical portion can be set larger than the height of the cooking hammer. Thereby, the operability of the cooking hammer is improved during the grinding operation and the kneading operation.

  The outer diameter of the second flat spherical portion can be set larger than the outer diameter of the first flat spherical portion. Thereby, the quantity of the to-be-processed foodstuff which can be processed at once can be increased, maintaining the operativity of the hammer for cooking.

  The range of the constant curvature radius of the curved surface of the recess of the cradle can be set larger than the range of the constant curvature radius of the curved bottom surface of the second flat spherical portion. Thereby, the surface contact state between the cooking hammer and the cradle is ensured within a predetermined range in which the central axis of the cooking hammer is displaced from the central axis of the cradle.

  According to the cooking utensil of the present invention, it is possible to perform a process of crushing or crushing a relatively large amount of food at a time with a relatively small force.

It is a perspective view which shows the external appearance of the cooking appliance of embodiment of this invention, especially the state lifted from the cradle. It is a perspective view which shows the external appearance of the cooking appliance of embodiment of this invention, especially the state mounted on the cradle. It is the sectional view on the AA line of the hammer shown in FIG. It is a BB sectional view of the cradle shown in FIG.

It is sectional drawing of both of the state which mounted the hammer in embodiment of this invention on the receiving stand.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<Configuration of the embodiment>
1 and 2 show the appearance of the cooking utensil of the present embodiment. This cooking utensil is a cooking utensil for processing ingredients, more specifically nuts (nuts), beans, peas, sesame, herbs (herb), rock salt, spices (including garlic), cereals, It is a cooking utensil for processing various foodstuffs. The illustrated cooking utensil includes a cooking hammer (hereinafter simply referred to as a hammer) 10 made of a rigid material having impact resistance, and a cradle 20 made of a rigid material having impact resistance. Prepare. FIG. 1 shows a state where the hammer 10 is lifted from the cradle 20, and FIG. 2 shows a state where the hammer 10 is placed on the cradle 20.

  The hammer 10 superimposes the first flat spherical portion 11, the second flat spherical portion 15, and the first and second flat spherical portions 11, 15 with their central axes aligned. And a constricted portion (connecting portion) 13 connected to each other.

  Typically, the 1st flat spherical part 11 functions as a handle part, and the 2nd flat spherical part 15 functions as a foodstuff contact part contact | abutted to a to-be-processed foodstuff.

  The cradle 20 has a recess 23 on the upper surface of the main body 21 for accommodating the entire second flat spherical portion 15 of the cooking hammer 10 with a margin. That is, the diameter of the circular outer edge of the recess 23 is set to be approximately 15 to 20% larger than the outer diameter of the flat spherical portion 15. The concave portion 23 has a curved bottom surface of the second flat spherical portion 15 and a bottom portion having a shape in surface contact with most of the region. Specific examples thereof will be described later.

  FIG. 3 is a cross-sectional view of the hammer 10 shown in FIG. As can be seen from this figure, the inside of the hammer 10 is densely constructed. In the present embodiment, the hammer 10 uses a metal (including an alloy) such as stainless steel (SUS) as its material, and includes a first flat spherical portion 11, a second flat spherical portion 15, and a constricted portion. Each part with 13 is comprised integrally. However, the hammer 10 is not limited to a metal, and can be made of, for example, a hard rigid material that has a relatively large specific gravity and is difficult to crack (has impact resistance).

  In the prototype of the applicant, the outer diameter of the first flat spherical portion 11 is about 70 mm, the outer diameter of the second flat spherical portion 15 is about 95 mm, and the weight of the hammer 10 is about 1.2 kg. The outer diameter of about 70 mm of the first flat spherical portion 11 is a suitable size that matches the average hand size of the user. The curvature radius of the curved bottom surface of the second flat spherical portion 15 is about 190 mm. The size (depth) of the constricted portion 13 is large enough to accommodate a user's average size finger (at least the thumb, index finger, middle finger and ring finger) and part of the hand. The depth of the constricted portion 13 can be set deep within a range that does not cause a problem in the strength of the hammer 10, but considering the ease of cleaning of the hammer 10, a shallower one is preferable. Accordingly, the depth of the constricted portion 13 is appropriately determined in consideration of these conflicting conditions.

  The outer diameter of the second flat spherical portion 15 is preferably larger than the outer diameter of the first flat spherical portion 11. That is, the outer diameter of the second flat spherical portion 15 is preferably as large as possible to process many foods at once. On the other hand, the larger the outer diameter is, the more the weight of the hammer 10 is increased and it becomes difficult for some users to handle. Therefore, the relationship (ratio) between both outer diameters of the first and second flat spherical portions 11 and 15 can be determined by the balance of both elements. The size and combination of these outer diameters do not necessarily have to be one way. For example, they may be different depending on the professional specification and general specification of cooking, or may be different depending on the type of food to be processed. Good.

  4 is a cross-sectional view taken along line BB along the diameter direction of the planar circular recess 23 of the cradle 20 shown in FIG. A constant radius of curvature in almost the entire region excluding the peripheral portion of the curved surface of the recess 23 is the same as that of the curved surface of the first flat spherical portion 15 of the hammer 10. With this configuration, it is ensured that the concave portion 23 is in surface contact with the curved bottom surface of the second flat spherical portion 15 in most of the region. Although the edge part following the curved surface of the recessed part 23 comprises the perpendicular | vertical wall in the example of a figure, a perpendicular | vertical wall is not an essential structure. For example, it may be a more gently inclined surface.

<Specific configuration of hammer 10>
FIG. 5 is an explanatory diagram of the configuration of the hammer 10 in the present embodiment.

  As can be seen from FIG. 5 (a), virtually, the vertical cross-sectional shape of the first flat spherical portion 11 of the hammer 10 is a portion of about three-quarters of the upper side of the first ellipse 11a. The vertical cross-sectional shape of the second flat spherical portion 15 is a portion of about 3/4 below the second ellipse 15a. The constricted portion 13 is connected between the flat spherical portions 11 and 15. As described above, the constricted portion 13 constitutes a recessed portion that has entered inside such that a part of the user's finger or hand can enter. The ratio of the ellipse portion is not limited to “three quarters”, but may be larger than ½.

  The three-dimensional shape of the hammer 10 having such a configuration is a three-dimensional shape formed by the locus of the plane when the plane having the shape as shown in FIG. 5B is rotated 360 ° about the rotation axis Z. It corresponds to. The shape of the constricted portion 13 is not particularly limited, but it is preferable that the constricted portion 13 has a curved shape that is recessed inward so that a part of a finger or a hand can be accommodated without difficulty and there is no sense of incongruity even when touched. However, this inwardly curved shape is not an essential element in the present invention. For example, as shown in FIG. 5C, the cross-sectional shape of the constricted portion 11a may be a non-curved shape. Although not shown, the hammer in this case also has a three-dimensional shape formed by the locus of the plane when the plane having the shape as shown in FIG. 5C is rotated 360 ° about the rotation axis Z. Equivalent to.

  In this example, the maximum width W21 of the second flat spherical portion 15 is set to be larger than the maximum width W11 of the first flat spherical portion 11. Further, the maximum width W11 of the first flat spherical portion 11 is set larger than the height H of the hammer 10.

  As can be seen from FIG. 5A, the width W12 of about 80% of the center of the maximum width W11 of the front shape (a part of the ellipse) of the first flat spherical portion 11 is sufficiently larger than the height H. It can be regarded as an arc of R1. The spherical portion of the first flat spherical portion 11 corresponding to this arc fits almost the entire palm of the user, and when performing hammering operation, crushing operation, crushing operation, kneading operation, etc. of the hammer 10 by hand. It is suitable for efficiently putting the weight on the hammer 10 and reliably transmitting the movement of the wrist to the hammer 10 without imposing an excessive burden on a part of the palm.

  Similarly, a width W22 of about 80% of the center of the maximum width W21 of the front shape (a part of an ellipse) of the second flat spherical portion 15 can be regarded as an arc having a constant curvature radius R2 sufficiently larger than the height H. . The spherical portion of the second flat spherical portion 15 corresponding to this arc cooperates with the concave surface curved with the same curvature radius R2 of the cradle 20 and scatters around the processed food distributed on the concave portion 23. It is useful to exert equal power while deterring things.

  FIG. 6 shows a cross-sectional view of the hammer 10 placed on the cradle 20. As described above, the curved bottom surface of the second flat spherical portion 15 and the curved concave surface of the concave portion 23 of the cradle 20 both have a radius of curvature R2, and the concave portion 23 is formed of the second flat spherical portion 15. Accommodate the whole with a margin. The range W31 of the curvature radius R2 of the curved bottom surface of the recess 23 is larger than the range W22 of the curvature radius R2 of the curved bottom surface of the second flat spherical portion 15. As a result, even if the central axis of the second flat spherical portion 15 and the central axis of the recess 23 are displaced within a predetermined range, the surface contact relationship between the hammer 10 and the cradle 20 is maintained. Therefore, not only when the hammer 10 strikes the cradle 20 unintentionally, but also when the center axis of both is shifted, the center axis of the hammer 10 is intentionally shifted from the center axis of the recess 23 during a grinding operation or the like. The surface contact relationship is also maintained.

  In addition, each part of the hammer 10 is not necessarily configured integrally. For example, the first and second flat spherical portions 11 and 15 configured separately are bonded to each other with a separate constricted portion 13. You may make it connect by connection means, such as joining and screwing. However, an integrated configuration is preferable from the viewpoint that the joints and joints are eliminated and the structure is robust, and the food is easy to clean and hygienic.

  The cradle 20 can be made of a hard rigid material that is hard to break, such as wood, metal, stone, and the like. From the viewpoint of strength, when the cradle 20 is made of wood, it is preferable to set the thickness of the bottom of the recess 23 to be larger than that of a metal. The shape of the main body 21 of the cradle 20 is a square (a short quadrangular prism shape), but may be another shape (for example, a circle or a polygon).

<Uses and effects of the embodiment>
When using the cooking utensil of the present embodiment, the user places a desired amount of food to be processed in the recess 23 of the cradle 20 within a range not exceeding an appropriate amount, and the first flat spherical shape of the hammer 10. The user wraps the portion 11 with a palm, grasps a plurality of fingers and a part of the hand so as to enter the constricted portion 13, and hits the food on the cradle 20 with the curved surface of the second flat spherical portion 15. The food is crushed or crushed by pushing, twisting or kneading.

  In a typical mode of use, for example, when nuts and the like are to be crushed to an appropriate size, the hammer 10 is lifted vertically above the cradle 20 on which a necessary amount of nuts and the like are placed, and the weight of the hammer 10 is increased. Use it to shake down the nuts. As a result, the hitting operation can be easily performed with a relatively small force, and an almost equal force is applied to all the ingredients on the cradle 20 from the relatively large curved bottom surface of the hammer 10, so that all ingredients are at the same level at a time. Can be crushed in size.

  If a finer crushing size is desired, the operation of swinging down the hammer 10 is repeated as many times as necessary. The size of the crushed food can be checked by the user immediately by lifting the hammer 10 each time. Therefore, the processing (for example, crushing operation | work) of the foodstuff in a favorite degree is attained. That is, the adjustment of the processing degree is easy and easy to understand.

  Further, by utilizing the weight of the hammer 10, the user is not required to have a greater force than necessary. If the height at which the hammer 10 is swung down is changed, the impact force on the processed food can be changed.

  Since the hammer 10 is relatively heavy (has a certain amount of weight), the hammer 10 is less likely to sway when the hammer 10 is raised or lowered. The specific gravity of the hammer 10 is preferably 2 or more, more preferably 4 or more, and most preferably 7 or more.

  By using the first flat spherical portion 11 having a relatively wide and gently curved surface as a handle portion, the weight of the user can be reduced without feeling pain in the palm of the hammer 10 when crushing food. It can be applied sufficiently and properly. In particular, by setting the size of the first flat spherical portion 11 to a predetermined size, most users can use it without any discomfort regardless of the hand size, finger length, and thickness of the user (adult). be able to.

  In addition, by using the first flat spherical portion 11 as a handle portion, the hammer 10 is not moved down straight to the cradle 20, but the curved bottom surface of the hammer 10 is wider in the recess 23 of the cradle 20. When performing an operation of shifting while making contact with the concave surface (particularly, an operation of crushing ingredients), it is easy to transmit such force.

  Since the concave portion 23 of the cradle 20 has a size that can accommodate the entire second flat spherical portion 15 of the hammer 10 with a margin, even if there is a slight lateral displacement when the hammer 10 is swung down, The risk of the edge of the hammer 10 coming into contact with the edge of the recess 23 of the cradle 20 is reduced.

  The hammer 10 is gripped by forming the planar shape (the shape seen from above) of the outer edges of the first and second flat spherical portions 11 and 15 of the hammer 10 into a circular shape and forming the constricted portions equally at 360 °. There is no need to consider the direction of the hammer 10 when the first flat spherical portion 11 is gripped, which improves usability. As for the cradle 20, by making the planar shape of the outer edge of the recess 23 circular, it is not necessary to consider the orientation of the cradle 20 and the usability is improved.

  Since the edge portion of the recess 23 of the cradle 20 is upright or inclined to a height exceeding the height of the edge portion of the second flat spherical portion 15, fragments such as crushed nuts are not easily scattered.

  Neither the hammer 10 nor the cradle 20 has any moving parts, and its external shape is relatively simple, so that cleaning is easy.

  Prior to the processing of the food to be processed, processing may be performed by laying a sheet (for example, cooking paper) having high water repellency and durability so as to cover at least the recess 23 of the cradle 20. Thereby, it is possible to prevent oil and moisture from the food material from adhering and penetrating into the cradle 20 (particularly in the case of wood). Since the processed foods after processing can be collected for each sheet, the collection becomes easy. Further, the necessity of cleaning the cradle 20 can be eliminated or reduced.

  The operation of the hammer 10 in this embodiment is completely manual work and does not require electricity as a driving force.

  By constituting the hammer 10 with stainless steel, it is hygienic and durability is improved.

  By making the second flat spherical portion 15 of the hammer 10 large to some extent, it can be used for various foods, from small items such as sesame to large items such as almonds.

  In the above description, it is assumed that the hammer 10 is brought into contact with the concave portion 23 of the pedestal 20 on the curved bottom surface of the second flat spherical portion 15 during use. On the other hand, in some cases (for example, when it is desired to apply the hammer 10 to only a part of the recess 23 of the cradle 20), the flat spherical portion 15 is formed so that the bottom surface of the flat spherical portion 15 is along the vertical direction. It is also possible to use a method in which the edge portion of the base plate is brought into contact with the concave portion 23 of the receiving base 20.

  The hammer 10 does not have a rod-like portion such as a pestle or a hammer handle, and is flat and is not bulky. When the hammer 10 is not used or stored, the hammer 10 can be stacked together with the cradle 20 to reduce the overall storage volume.

  After processing the food with the hammer 10, when it is desired to temporarily place the hammer 10 in a place other than the cradle 20, if the food contact part is lowered, the food contact part comes in direct contact with the place to be placed. Not only is it unsatisfactory, but also the debris of the food material adhering to the food material contact portion adheres to the place of placement. In order to prevent this, it is necessary to prepare a tray or the like separately and place the hammer 10 thereon. However, since the upper surface of the first flat spherical portion 11 as the handle portion of the hammer 10 of the present embodiment is flat, it can be stably placed on an arbitrary flat place by simply turning the hammer 10 upside down. .

  The hammer 10 having an external shape as shown in the figure is beautiful as an object while having a relatively simple design.

<Other variations>
The preferred embodiments of the present invention have been described above, but various modifications and changes other than those mentioned above can be made.

  For example, although a configuration in which grooves or irregularities are not provided as the surface shape of the bottom surface of the hammer 10 and the recess 23 of the cradle 20 is shown, the present invention does not provide grooves or irregularities on the bottom surface of the hammer 10 and the surface of the recess 23 of the cradle 20. It is not excluded to provide (eg, rough particles, jagged protrusions, etc.).

  The numerical values of the sizes and weights of the respective parts described above and the details of the specific shapes shown in the drawings are merely examples for explanation, and are not intended to limit the present invention.
