Description

[Detailed description of the invention]   [0001]     [Technical field to which the invention belongs]   The present invention relates to a cooking device that stirs a cooking object by rotating blades in a cooking pot. In addition, the present invention relates to a cooking device suitable for cooking for a large number of people, such as for lunch and business use.   [0002]     [Prior art]   When cooking for many people, the amount of food to be cooked is large, It is common practice to rotate and cook. Hand that mechanically rotates the food As a step, in addition to the rotary method in which the cooking pot is rotated, feathers are set inside the fixed cooking pot. There is a stirring blade system that stirs the food by rotating the root.   Generally, the stirring blades rotated along the inner wall of the cooking pot to scoop up the food. After that, the stir-fry ingredients are lifted to the top of the cooking pot and dropped from the stirring blades. Agitate. If there is a gap between the stirring blade and the inner wall of the cooking pot, It is possible to effectively scoop up the food adhered to the inner wall of the pot with stirring blades For example, when cooking is stir-fried, the object to be cooked adheres to the inner wall of During the standing and stir-fry, kogation occurs and the quality of the stir-fry is significantly impaired. Conversely, stirring blades If there is no gap between the root and the inner wall of the cooking pot, the stirring blades will be locked and smooth Rotation is inhibited.   [0003]   Therefore, conventionally, the stirring blades are made of a plate-like wooden piece with little frictional resistance with the inner wall of the cooking pot. This piece of wood is constantly pressed against the inner wall of the cooking pot to attach it to the inner wall of the cooking pot. Scratching the cooked item was performed. Also, cooking pot with spring Press the agitating blades against the inner wall to scrape off the food adhered to the inner wall of the cooking pot. There is also one (for example, Patent Document 1).   [0004]       [Patent Document 1]   JP 2000-253993 A (paragraph number 0010, FIGS. 7 to 15)   [0005]     [Problems to be solved by the invention]   However, according to the above-described conventional technology, the one in which the stirring blade is made of a piece of wood is circular. While ensuring smooth rotation, scrape the cooking object adhered to the inner wall of the cooking pan with appropriate pressing force. Can be laid down, but wooden agitating blades were severely worn due to contact friction with inner wall Therefore, there is a problem that the life is short and the frequency of replacement becomes high. Also, due to contact friction There is also a problem that unevenness occurs during use due to uneven damage.   [0006]   Further, in the device described in Patent Document 1 in which a spring is pressed, a blade is made of metal. Even though the pressure can be adjusted, there is no problem with the life like a wooden blade, The spring structure becomes complicated, and the spring structure protrudes further. However, there is a problem that the object to be cooked adheres to the food. Also, the cooking object has a spring structure If it adheres to the part, it will have to be scraped by hand and the cooking speed will decrease. There was also the problem of doing.   [0007]   The problem to be solved by the present invention is to solve the above-mentioned problems of the prior art, to provide a long service life and a structure. Despite being simple, the adherence to the cooking pot is reduced and the food is cooked quickly and evenly. To provide a cooking device capable of stirring.     [Means for Solving the Problems]   The present invention has a stirring blade rotating around a horizontal axis inside a cooking vessel, In a cooking device for stirring and cooking an object to be cooked by rotation of a blade, the stirring blade Are fixed blades that rotate in a non-contact state with the inner wall of the preparation container, and the fixed blades It is provided so as to be slidable toward the inner wall of the cooking vessel, and while the fixed blade rotates once. Over a predetermined angle range, by its own weight against the frictional resistance with the fixed blade A movable blade that slides and contacts an inner wall of the cooking container. Cooking device.   [0008]   Since the stirring blades consist of fixed blades and movable blades, the fixed blades stir the food to be cooked. Mixing can be performed, and the movable blades can scrape off the food adhered to the inner wall. it can. In addition, since the fixed blade rotates without contact with the inner wall of the preparation container, Stirring can be performed. In addition, since the movable blade contacts the inner wall of the cooking vessel, The cooking object adhered to the wall can be reliably scraped off. In addition, the movable blade has a predetermined angle The cooking object attached to the inner wall in that range. You can continue scraping. In addition, the movable blades hit the inner wall of the cooking container by its own weight. Because it contacts, only by adjusting the weight of the movable blade, It becomes possible to obtain a scraping force. Also, since the movable blade slides under its own weight, No special power is required, and the slide mechanism is simplified.   [0009]     [Embodiment of the invention]   Hereinafter, an embodiment of the cooking device of the present invention will be described.

Turn the switch of the switch box 5 to rotate the stirring blade 30, The food is stirred and cooked. After cooking, stop gas and operate handle 3 to adjust The container 2 is tilted greatly, and the food is taken out from the opening 20 into a receiver (not shown). You.   [0015]   As shown in FIG. 1, a cooking pot 21 integrally formed in the cooking container 2 has a semi-cylindrical shape. And a rectangular body 23 rising from the bottom 22. Consists of The body 23 constitutes a part of the cooking container 2. Cooking pot 21 is gold Although it is formed with a genus, for example, iron that is easily compatible with oil is preferable.   [0016]   A rotating shaft 33 is rotatably provided on the cooking pot 21. Rotating shaft 33 is semi-cylindrical It is inserted through the center of the cylindrical shape constituting the bottom part 22. The rotation axis 33 is The rotation speed can be changed by the data.   [0017]   As shown in FIG. 2, a stainless steel stirrer for stirring the object to be cooked is The rolling frame 40 is integrally mounted. The rotating frame 40 has a rectangular shape And two on both sides of the frame having a length slightly shorter than the cylindrical diameter of the cooking pot 21. A flat bar-shaped support member 34 and a semi-cylindrical shape attached to the support member 34 It has two plate-shaped fixed blades 31 having a length slightly shorter than the length of the bottom. The two support members 34 have their central portions connected to a rotating shaft 33 arranged in the cooking pot 21. It is inserted and fixed to both sides of the rotating shaft 33. The two plate-shaped fixed blades 31 are provided with a rotating shaft. 33 are respectively connected between the same side ends of two support members 34 fixed to both sides of And extend along the inner wall 21 a in the axial direction of the cooking pot 21, and Arrange them symmetrically. The rotating frame 40 holds the object twice during one rotation. It is possible to stir. The above-mentioned pair of rotating frames 40 are rotated upward. The lower part may be opposite, but for convenience, one part is rotated upward with the rotation axis 33 as a boundary. The frame 41 and the other are referred to as a lower rotating frame 42.   [0018]   As shown in FIG. 1 (b), the plate-shaped fixed blade 31 is a flat bar-shaped support member 3. 4, the front and back surfaces of the fixed blade 31 are parallel to the length direction of the support member 34. , That is, in such a manner as to face in the radial direction of the cylinder about the rotation axis 33. This Attaching the fixed blade 31 in an orientation like That. Therefore, the movable blade 32 slides radially inward with respect to the fixed blade 31. Will do. When the movable blade 32 abuts against the inner wall 21a of the cooking pot 21, Attach the fixed blade 31 at an angle to the support member 34 to accelerate the period (See FIG. 5).   [0019]   A gap is formed between the fixed blade 31 and the inner wall 21a of the cooking pot 21 so that the fixed blade Reference numeral 31 denotes a non-contact with the inner wall 21a. Therefore, fixing without forming a gap The stirring blade 30 is not locked as compared with the one in which the blade is Smooth rotation of the blade 30 can be ensured. The formed gap corresponds to a movable blade 32 described later. Covered by In the illustrated example, the rotating frame 40 has a rotating shaft 33. A pair of shafts are provided in line symmetry, but only one is provided on one side of the rotating shaft 33. Alternatively, three or more radial lines may be provided around the rotation axis.   [0020]   Although the width of the fixed blade 31 of the rotating frame 40 is large, the fixed blade 31 A movable plate 32 made of stainless steel and having substantially the same shape as the above is provided. Movable feather 32 is slidably attached to the inner wall 21a of the cooking pot 21. this The mechanism for slidably attaching is provided with a pin (bore) in an elongated hole 35 provided in the movable blade 32. The movable blade 32 is connected to the fixed blade 31 through the Do. As shown in FIG. 2, the fixed blades 31 have equal intervals along the length direction thereof. A plurality of pins 36 are mounted on a straight line. This pin 36 extends to the head And the leg is formed of a screw and is screwed to the fixed blade 31. . On the other hand, a vertically long slot 35 is formed through the movable blade 32 in the width direction of the blade. . The elongated holes 35 correspond to the plurality of pins 36 attached to the fixed A plurality are formed at equal intervals along the length direction. The width of the long hole 35 is the pin head. The elongated hole 35 comes out of the pin 36, and the movable blade 32 is fixed to the fixed blade. It does not fall from the root 31.   [0021]   As shown in FIG. 2, the movable blade 32 is superimposed on the fixed blade 31 and the pin 36 is inserted into the elongated hole 35. , And screwed to the fixed blade 31 to move the movable blade with respect to the fixed blade 31. Attach 32. In this installation, the first movable When the blade 32 is attached to the front of one fixed blade 31, the second movable blade 32 It may be attached to the back surface of the other fixed blade 31. As a result, the movable blade 32 It becomes slidable along the long hole 35 within a range where the 36 moves in the long hole 35. Slot 35 The number of pins 36 is preferably an odd number that makes it difficult for the movable blade 32 to lock when sliding. New In addition, the relation between the pin and the long hole is reversed, and the movable blade 32 is provided with the pin 36, An elongated hole 35 may be provided in the fixed blade 31.   [0022]   As shown in FIG. 1 (b), the movable blade 32 that rotates clockwise rotates the upper rotating frame. The first rotation angle θ in the bottom portion 22 (when the rotation start position is the uppermost portion, When the angle exceeds the angle formed by the vertical line), the cooking pot 21 slides radially outward by its own weight. Abuts against the inner wall 21a of the bottom portion 22 of the base. From the first rotation angle θ to the second rotation angle φ Abuts on the inner wall 21a of the bottom portion 22 while rotating the angle range (φ-θ) at While maintaining the state, the object to be cooked attached to the inner wall 21a of the bottom portion 22 of the cooking pot 21 is scraped off. . When the second rotation angle φ opposite to the first rotation angle θ in the bottom portion 22 is exceeded, The blade 32 slides radially inward by its own weight and separates from the inner wall 21 a of the cooking pot 21. It has become.   [0023]   When the fixed blade 31 is attached without an angle, the first rotation angle θ is 90 The angle is in the range of ° to 180 °. The second rotation angle φ is 270 ° to 360 ° Angle within the range. These angles determine the frictional resistance between the fixed blade 31 and the angle. It can be adjusted by the weight of the moving blade 32. In addition, the weight of the movable blade 32 is It is appropriately determined according to the product and the content of cooking. The fixed blade 31 and the movable blade 32 described above Thus, the stirring blade 30 of the present invention is configured.   [0024]   Now, the operation of the above configuration will be described.   [0025]   Initially, as shown in FIG. 1, a pair of rotating frames 40 fixed to the rotating shaft 33 are The rotating frame 40 rotates clockwise from this position as the starting point. This will be described with reference to FIG. In the initial vertical position, the upper rotating frame The movable blade 32 attached to the movable member 41 has its own weight W which is a radially inward component W. _I Therefore, the upper portion of the long hole 35 is hooked on the pin 36, and It is in the retracted position. Lower part 180 ° opposite to upper rotating frame 41 On the other hand, the movable blade 32 attached to the rotating frame 42 Direction outward component W_OAs a result, the inner wall 2 of the bottom 22 protrudes radially outward. 1a.   [0026]   Looking at the upper rotating frame 41, as the rotating shaft 33 rotates from the initial position, As the movable blade 32 rotates, the force applied to the movable blade 32 is orthogonal to the radial direction. Directional component W_RAppears, and its component W increases as the rotation angle increases._RGrows larger . When the movable blade 32 comes to a horizontal position at a rotation angle of 90 °, the radial inner component W_IIs And the weight W of the movable blade 32 is all orthogonal component W_RBecomes And times When the rotation angle exceeds 90 ° and enters the bottom 22 of the cooking pot 21, the radial component reverses. , This time the radial inward component W_IInstead of W_OAppears and the amount of rotation The value increases accordingly. Then, the rotation proceeds further, and Min W_OWhen the movable blade 32 overcomes the frictional resistance inward in the radial direction, the movable blade 32 slides outward in the radial direction. And the radially outward component W_OInner wall 21 of bottom 22 of cooking pot 21 Collide with a. From this collision point (first rotation angle) to the inner wall 21a of the cooking pot 21 The scraping of the adhered food is started. 180 ° true rotation frame 40 When it comes to the lower position, all of its own weight W is radially outward component W_OAnd the movable blades 32 The weight is completely hung on the pin 36 by its own weight, and the pushing force is maximized. The movement of the upper rotating frame 41 is the same as the movement of the lower rotating frame 42 thereafter. Become.   [0027]   Looking at the lower rotating frame 42 that starts rotating from the initial position, As the movable blade 32 rotates with the rotation of the rotation shaft 33, the movable blade 32 Component W in the direction orthogonal to the radial direction_RAppears as the rotation angle increases. Component W_RIs getting bigger. The movable blade 32 is in a horizontal position with a rotation angle of 90 °. When it comes, radial outer component W_OIs zero, and the weights W are all orthogonal components W_RBecomes When the bottom portion 22 is removed beyond the rotation angle of 90 °, the radial component reverses. , This time the radially outward component W_OIs W instead of W_IAppears and the amount of rotation The value increases accordingly. Then, the rotation proceeds further, and the radial inward Min W_IWhen the movable blade 32 overcomes the radially outward frictional resistance, the movable blade 32 slides radially inward. Iid and withdraw. When the rotating frame 40 comes to a position directly above 180 °, its own weight W becomes All radial inward components W_IThe movable blade 32 completely hits the pin 36 under its own weight. And the retraction force is maximized.   [0028]   The front edge of the movable blade 32 that abuts on the inner wall 21a has a rotating gauge as shown in FIG. Draw trace T. That is, during one rotation, the movable blade 32 moves from the angle θ to the angle At a rotation angle up to the degree φ, the inner wall 2 of the bottom 22 protrudes radially outward due to its own weight. 1a, retracts in the angle range from the angle φ to the angle θ, and the inner wall of the bottom 22 21a is not in contact. These protruding position (first rotation angle) and retracted position (The second rotation angle) is exactly 180 ° opposite.   [0029]   Now, the rotating frame 40 rotates along the inner wall 21a of the cooking pot 21 and stirs. After scooping up the material, it is lifted to the upper part of the cooking pot 21 and dropped from the stirring blade 30. Stir the stir fry material by letting it go. In response, the movable blade 32 is Since such a locus is drawn, the inner wall 21a of the bottom 22 of the lower half of the cooking pot 21 is movable. There is no gap between the blade 32 and the inner wall 21a of the cooking pot, and the blade 32 adheres to the inner wall 21a. The object to be cooked can be effectively scraped and scooped by the movable blades 32. it can. Therefore, the object to be cooked may adhere to and stay on the inner wall 21a of the cooking pot. And the quality of the stir-fry is not impaired. Disappears.   [0030]   Further, according to the present embodiment, the movable blade 32 slides by its own weight and slides on the inner wall 21a. , And scrapes the food adhered to the inner wall 21a of the bottom portion 22 of the cooking pot 21. Therefore, no gap is formed between the inner wall 21a and the rotating shaft. That simply fix the stirring blades to the blade, or that press the stirring blades against the inner wall with a spring As compared with, appropriate force according to the weight of the movable blade 32 without a complicated structure Thus, the food adhered to the inner wall 21a can be scraped off. The movable blade 32 The rotation of the stirring blade 30 is locked because the contact force against the inner wall 21a depends on its own weight. On the contrary, smooth rotation of the stirring blade 30 can be maintained. The movable blade 32 is under its own weight. Because it has a unique movable wing structure, it does not require special power and saves labor. Can be Further, the collision force or the contact force against the inner wall 21a is the weight of the movable blade 32. Since it can be adjusted by a frictional resistance or the like, the movable blade 32 damages the inner wall 21a. It is easy to increase scratching ability while minimizing scratches. further, The structure of the movable blade 32 is simple because the slide mechanism of the movable blade 32 is connected by a pin. Further, the stirring blade can be easily replaced simply by releasing the pin connection.   [0031]   According to the present embodiment, the case where cooking is stir-fried has been described, Specifically, stir fried rice, yakisoba, yakiniku, spaghetti, nectar, menma etc. In addition to cooking, croquettes and hamburger ingredients, meat, curry, stew, gyudon, meat It can be used for stir-fried cooking of potatoes, as well as for various soups and sauces. You.   [0032]   In the above-described embodiment, the movable blade 32 enters the bottom 22 of the cooking pot 21. Before contacting the inner wall 21 a, but before entering the bottom 22, You may want to do that. FIG. 5 shows such a modification.   [0033]   The fixed blade 31 is attached to the support member 34 at an angle. This angle is Determined according to the request for the scraping start angle. Applicable to the fixed blade 31 with this angle The moving blade 32 is attached. In this case, in the rectangular body before entering the semi-cylindrical bottom, After the rotation angle α (<θ), the movable blade 32 slides outward in the radial direction and The movable wings earlier than when mounted without an angle. The root 32 can abut. In addition, it has advanced by 180 ° from the rotation angle α. After the rotation angle β (<φ), the movable blade 32 is retracted inward in the radial direction and is not in contact. Becomes   [0034]   【Example】   The cooking pot capacity is 144 liters and the pot thickness is 6mm thick black which is ideal for stir-fry and stew. A thick steel plate was used. In addition, rotating frames other than cooking pots and The moving blades are made of stainless steel which is durable, washable and sanitary.
