DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The object of the present invention is to provide an agitating blade capable of more uniformly agitating an object to be agitated, and an agitating device equipped with such an agitating blade. An agitation blade for use in an agitation device having a container for accommodating an object to be agitated, the agitation blade comprising: a shaft rotated by the agitator; A first blade body; A second blade body; a first connecting member that connects the first blade body and the second blade body; Equipped with The first blade body is connected to the shaft, The above problem has been solved by providing an agitator blade and an agitator using an agitator blade configured in such a way that the first blade body and the second blade body are configured such that, when the shaft is rotated by the agitator, at least a portion of the material to be stirred contained in a container and scooped up by the first blade body moves onto the second blade body via the first connecting member.

[0010] The stirring device includes at least a container for accommodating the object to be stirred, and a first driving means for rotating the stirring blade (shaft). The container may have any shape. In a preferred embodiment, the container has a substantially hemispherical bottom, but is not limited to this. By making the container have a substantially hemispherical bottom, more uniform stirring is possible compared to a container having a flat bottom. In addition, by making the bottom a hemispherical body, the thickness of the container can be made thin, which allows heat to be conducted uniformly throughout the container.

[0011] The first driving means for rotating the stirring blade (shaft) may be disposed in any position. In a preferred embodiment, the first driving means is provided in a state inclined with respect to the stirring device, but the present invention is not limited thereto. For example, the first driving means may be provided in a horizontal state or in a substantially vertical state.

[0012] The stirring device may further include a second driving means for rotating the container. By rotating the container, the object to be stirred can be stirred more efficiently.

[0013] The stirring device may also be provided with a heating means for heating the container. By providing the heating means, for example, when the object to be stirred is food, it becomes possible to simultaneously cook and stir the food.

[0014] The stirring device may further include a control means for controlling the rotation speed of the container and the rotation speed of the stirring blade (shaft). By controlling the rotation speed of the container and the rotation speed of the stirring blade to predetermined conditions, it becomes possible to stir the material to be stirred more efficiently.

[0015] The mixing blade comprises at least a shaft that can be attached to a first driving means of the mixing device, a first blade body connected to the shaft, a second blade body, and a first connecting member that connects the first blade body and the second blade body.

[0016] The shaft may have any shape. In one embodiment, the shaft is a member having a substantially straight axis, but the present invention is not limited thereto. For example, the shaft may be curved, such as helical.

[0017] The shape and size of the blades may be arbitrary. In one embodiment, the cross section is a flat plate-like body, but is not limited thereto. The cross section may be substantially concave so as to efficiently accommodate the object to be stirred in the container.

[0018] In addition, the shape of the cutting edge surface of the blades facing the inner surface of the container may be arbitrary. In a preferred embodiment, the shape of the cutting edge surface is a shape that conforms to the shape of the inner surface of the container. In one embodiment, in a substantially hemispherical container, the shape of the cutting edge surface of the blades is substantially arc-shaped, but is not limited thereto. For example, it may be substantially crescent-shaped, substantially triangular, or substantially rectangular in plan view. By forming the cutting edge surface into a shape that conforms to the shape of the inner surface of the container, it is possible to efficiently scoop up the object to be stirred in the container.

[0019] The length of the cutting edge surfaces of the plurality of blades may be arbitrary. The lengths of the cutting edge surfaces of the plurality of blades may all be the same length, may be different lengths, or some of the blades may be the same length.

[0020] In a preferred embodiment, when the blade has three blades, the length of the cutting edge of the second blade is shorter than the length of the cutting edge of the third blade, and the length of the cutting edge of the first blade is the longest. This relationship in length between the cutting edges of the three blades provides the following effects.

[0021] The blade tip of the first blade body scoops up the material to be stirred at approximately the center of the container, and since the material to be stirred is concentrated approximately at the center of the container, by increasing the length of the blade tip of the first blade body, it is possible to increase the amount of material to be scooped up, and the role of this first blade body, that is, the role of scooping up the material to be stirred and the role of lifting and dropping the scooped material to be stirred, can be performed more effectively. Since the second blade body not only lifts and drops the material to be stirred scooped up by the second blade body itself, but also lifts and drops the material to be stirred that has been scooped up by the first blade body and moved from the first blade body, by shortening the length of the blade tip of this second blade body compared to the first blade body, the material to be stirred from the first blade body is more likely to fall around the area (center) in the container where the first blade body scoops up the material to be stirred, and more uniform stirring of the material to be stirred in the horizontal direction is possible. The third blade body, like the second blade body, lifts and drops not only the objects scooped up by the third blade body itself, but also the objects scooped up by the second blade body and moved from the first blade body. However, the third blade body is located on the outer periphery of the container where there is less objects present than the second blade body, and its main function is to scrape off the objects scattered on the inner surface of the container. Therefore, in order to efficiently scrape off the objects scattered over a wide area, it is preferable to make the blade longer than the blade tip of the second blade body. By making the length of the blade tip of the third blade body shorter than that of the first blade body, the stirring blade can be made compact while achieving the desired effect. Depending on the type or amount of objects to be stirred, such as ingredients, if the objects scattered on the outer periphery of the container reach a higher position on the container, the length of the blade tip of the third blade body may be longer than the length of the blade tip of the first blade body. Furthermore, since the third blade body scoops up the material to be stirred on the outer periphery of the container, and the amount of material to be stirred on the outer periphery is less than the material to be stirred on the approximate center or approximate radial center of the container, it is preferable that the area of ​​the fanning surface of the third blade body is smaller than the area of ​​the fanning surfaces of the first blade body and the second blade body.

[0022] The first connecting member may be of any shape as long as it connects the first blade body and the second blade body. In one embodiment, it is a flat plate-like body similar to the blade body, but is not limited thereto. The first connecting member connects the first blade body and the second blade body so that the object to be stirred scooped up by the first blade body can move from the first blade body to the second blade body by the rotation of the shaft. The area of ​​the object to be stirred that can be scooped up in the container by the first blade body and the area of ​​the object to be scooped up in the container by the second blade body are configured to be at least partially different. In one embodiment, the area that can be scooped up by the first blade body is approximately the center of the container, and the area that can be scooped up by the second blade body is an area on the outer periphery side of the container from the area that can be scooped up by the first blade body.

[0023] For example, the first blade body and the second blade body may be configured such that at least a portion of the object to be stirred present on the second blade body falls from the second blade body due to the object to be stirred moving from the first blade body to the second blade body.

[0024] The blade body may be three or more. Similarly, when three or more blade bodies are provided, the area of ​​the object to be stirred that each blade body can scoop up in the container is configured to be at least partially different, and the area of ​​the object to be scooped up in the container of each of the blade bodies is configured to move to the outer periphery of the container in order from the first blade body. At least a part of the object to be stirred present on the second blade body may be moved to the next third blade body connected to the second blade body by the object to be stirred moving from the first blade body to the second blade body, without falling from the second blade body, and may be configured to fall from the third blade body.

[0025] The mixing blade may also have a third blade body and a second connecting member connecting the second blade body and the third blade body, and at least a part of the material to be mixed scooped up by the rotation of the shaft on the second blade body may move onto the third blade body via the second connecting member. Furthermore, the first blade body, the second blade body, and the third blade body may be configured such that at least a part of the material to be mixed present on the third blade body falls from the third blade body due to the material to be mixed moving from the second blade body to the third blade body.

[0026] The mixing blade may also be provided with four or more blade bodies and three or more connecting members connecting adjacent blade bodies, and at least a part of the material to be mixed scooped up by one blade body by the rotation of the shaft may move onto another blade body adjacent to the one blade body via the connecting member. Furthermore, the four or more blade bodies may be configured so that at least a part of the material to be mixed present on one adjacent blade body falls from one blade body due to the material to be mixed moving from the other adjacent blade body to one blade body.

[0027] In addition, the multiple blade bodies constituting the stirring blade are not particularly limited in the size relationship of the surface area that scoops up the stirred material, and can be any. In a preferred embodiment, the multiple blade bodies are a first blade body, a second blade body, and a third blade body, and the area of ​​the first blade body that scoops up the stirred material at approximately the center of the container is made large, and since an area is required to receive the part of the stirred material scooped up by the first blade body that is moved and an area is required for the second blade body itself to scoop up the stirred material at the outer periphery side of the container from the first blade body, the area of ​​the second blade body is made larger than the area of ​​the first blade body. The objects to be stirred that can be scooped up by the third blade body are near the outer circumferential edge of the container, and the objects to be stirred that can be scooped up by the third blade body itself are few, and the area that receives the objects to be stirred scooped up by the second blade body is the majority, so the area of ​​the third blade body is configured to be smaller than the first blade body and the second blade body. However, the present invention is not limited to this. For example, the surface area of ​​the first blade body that scoops up the material to be stirred may be configured to be maximum, the surface area of ​​the third blade body that scoops up the material to be stirred may be minimum, and the surface area of ​​the second blade body that scoops up the material to be stirred may be smaller than the surface area of ​​the first blade body and larger than the surface area of ​​the third blade body; alternatively, the areas of the first blade body and the second blade body may be the same and the area of ​​the third blade body may be smaller than the areas of the first blade body and the second blade body; or the areas of the first blade body, the second blade body, and the third blade body may all be the same.

[0028] In addition, the multiple blade bodies constituting the stirring blade are configured so that the height and radial position relative to the container are different when the blade body is in a position where the most amount of the object to be stirred can be scooped up, that is, when the surface scooping up the object to be stirred is approximately parallel to the radial direction (approximately horizontal direction) of the container. In a preferred embodiment, the first blade body, the second blade body, and the third blade body are configured so that the position where the surface of the second blade body is approximately horizontal is higher than the position where the surface of the first blade body is approximately horizontal and is located on the outer periphery of the container, and the position where the surface of the third blade body is approximately horizontal is higher than the position where the surface of the second blade body is approximately horizontal and is located closer to the outer periphery of the container. In this case, the positions where the stirring efficiency of each blade body is highest are distributed in the height direction and radial direction of the container, and stirring can be performed uniformly throughout the container.

[0029] Furthermore, in the stirring device, the drive means for rotating the container and the drive means for rotating the shaft of the stirring blade are not particularly limited in their specific configurations as long as they have the function of rotating the container or the shaft. Preferably, the shaft rotation speed (rotation speed per unit time) and the container rotation speed (rotation speed per unit time) are configured to be different rotation speeds that have no common divisor other than 1. By making the rotation speed of the stirring blade and the rotation speed of the container different and having no common divisor other than 1 in this way, the frequency with which the tip edge (tip part) of each blade body returns to the same position on the inner surface of the container can be reduced, and the object to be stirred can be stirred more uniformly. For example, by setting the rotation speed of the stirring blade to 12 rpm and the rotation speed of the container to 7 rpm or 13 rpm, rather than setting the rotation speed of the stirring blade to 12 rpm and the rotation speed of the container to 8 rpm, it is possible to reduce the number of times each blade body of the stirring blade comes to the same place of the container from 4 times to 1 time per unit time (for example, 1 minute).

[0030] The material constituting the container may be any material. For example, when the container is used for stirring the object to be stirred while heating it, the material constituting the container is a metal material such as iron, copper, or stainless steel. However, the present invention is not limited thereto. When stirring is not performed at high temperatures, the material constituting the container may be a resin material or the like.

[0031] The material constituting the blade body may be any material. For example, the material may be a metal material such as iron, copper, or stainless steel, but is not limited to these. For example, the material may be a resin (preferably a fluororesin with good sliding properties), or a resin may be attached to the surface of a metal.

[0032] As described above, the agitator blade of the present invention is not particularly limited in other configuration as long as at least a portion of the material to be agitated is scooped up by the rotation of the shaft onto the first blade body connected to the shaft and moves onto the second blade body via the first connecting member. However, in the following embodiment, an agitator blade having three blade bodies (first blade body, second blade body, third blade body) and two connecting members (first connecting member and second connecting member) is given, and the specific configuration of the three blade bodies is described.

[0033] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0034] (Embodiment 1) FIG. 1 is a diagram for explaining an agitator blade 100 according to embodiment 1 of the present invention, where FIG. 1(a) shows the agitator blade 100 used in an agitator 300 having a container 200, FIG. 1(b) conceptually shows the agitator 300 shown in FIG. 1(a) with the agitator blade 100 and container 200 removed, FIG. 1(c) shows an enlarged view of the agitator blade 100 of the agitator 300 shown in FIG. 1(a), and FIG. 1(d) shows the structure of the agitator blade 100 shown in FIG. 1(c) viewed from the Ax direction.

[0035] As shown in Fig. 1(a), the stirring blade 100 of the first embodiment is an stirring blade used in a stirring device 300 having a container 200 that contains a stirred object A. As shown in Fig. 1(c) and Fig. 1(d), the stirring blade 100 includes a shaft 10 rotated by the stirring device 300, a first blade body 110, a second blade body 120, and a third blade body 130, and further includes a first connecting member 20a that connects the first blade body 110 and the second blade body 120, and a second connecting member 20b that connects the second blade body 120 and the third blade body 130.

[0036] Here, the shaft 10 has a shaft body 10a and a connecting member 10b provided at the end on the base side of the shaft body 10a. One end of the first blade body 110 is connected to the tip side of the shaft body 10a, and one end of the third blade body 130 is fixed to the base side portion of the shaft body 10a by a fixing member 30. The connecting member 10b is structured so as to be detachable from the rotating shaft 101a of the blade mounting head 310.

[0037] The container 200 also includes a container body 201 that contains the object A to be stirred, and a support flange 202 that supports the container body 201. The support flange 202 is a ring-shaped member attached to the outer surface of the container body 201, and the container body 201 has a shape obtained by cutting out a part of a sphere (for example, a substantially hemispherical shape, or a shape of a part of a sphere with an end face having a smaller radius than a hemisphere). The relative positional relationship between the container 200 and the mixing blade 100 is adjusted so that all three blade bodies that constitute the mixing blade 100 are in zero-point contact or non-contact with the inner surface of the container body 201.

[0038] Further, in addition to the above-mentioned impeller 100 and container 200, the stirring device 300 includes, as shown in FIG. 1(a) and FIG. 1(b), an apparatus housing 300a, an impeller support head 310 that rotatably supports the impeller 100, and a container support mechanism 320 that rotatably supports the container 200. The impeller support head 310 is attached to the apparatus housing 300a, the container support mechanism 320 is built into the apparatus housing 300a, and a container accommodation hole 303a that can accommodate the bowl-shaped container body 201 is formed on the upper surface of the apparatus housing 300a. The impeller support head 310 includes an impeller drive means (first drive means) 310a that rotates the impeller 100, and the container support mechanism 320 includes a container drive means (second drive means) 320a that drives the container 200 by rotating the support flange 202 attached to the container body 201. The first driving means 310a and the second driving means 320a are, for example, electric motors.

[0039] (Mixing blade 100) The stirring blade 100 will be described in detail below.

[0040] The three blade bodies 110, 120, 130 that constitute the mixing blade 100 when the shaft rotates have blade tips 110a, 120a, 130a that have the function of scooping up the material to be mixed that is present on the inner surface of the container body 201 of the container 200, and surfaces (fanning surfaces) 110b, 120b, 130b that have the function of lifting the material to be mixed scooped up by the blade tips 110a, 120a, 130a and the function of dropping the lifted material to be mixed.

[0041] The shape of the blade tip and the fanning surface are configured so that the vane body effectively works as a fanning action by scooping up the object to be stirred from the inner surface of the container body 201 (first action) and by lifting up the scooped object to be stirred and dropping it (second action). The role of each vane body will be explained in detail below.

[0042] FIG. 2 is a plan view for explaining a plurality of blade bodies constituting the stirring blade 100 shown in FIG. 1(c). FIG. 2(a) shows the first blade body 110, FIG. 2(b) shows the second blade body 120, and FIG. 2(c) shows the third blade body 130.

[0043] The first blade body 110 has a substantially arc-shaped blade tip portion 110a having a length L1 and a planar fanning surface 110b having an area S1 (see FIG. 2(a)). The second blade body 120 has a substantially arc-shaped blade tip portion 120a having a length L2 and a planar fanning surface 120b having an area S2 (see FIG. 2(b)). Further, the third blade body 130 has a substantially arc-shaped blade tip portion 130a having a length L3 and a planar fanning surface 130b having an area S3 (see FIG. 2(c)).

[0044] Here, the magnitude relationship of the length L1 of the blade tip portion 110a of the first blade body 110, the length L2 of the blade tip portion 120a of the second blade body 120, and the length L3 of the substantially arc-shaped blade tip portion 130a of the third blade body is L2 < L3 < L1.

[0045] The fanning surface area S1 of the first blade body 110 is smaller than the fanning surface area S2 of the second blade body 120 and larger than the fanning surface area S3 of the third blade body. Such a magnitude relationship of the fanning surface areas (S3 < S1 < S2) is based on the peripheral speed of the rotating container body 201 and the roles played by each of the three blade bodies, as will be described below.

[0046] First, the following can be said from the viewpoint of the peripheral speed of the container 200.

[0047] In the blade body (first blade body 110) arranged on the center side of the container 200 where the circumferential speed of the container 200 is slow, it is preferable to make the fan surface area S1 larger than the blade bodies (second blade body and third blade body) arranged on the peripheral side of the container body 201 where the circumferential speed of the container body 201 is fast, so that more objects to be stirred can be scooped up and placed on the fan surface 110b without dropping them. In this way, in the blade body located in the part of the container body 201 where the circumferential speed is fast, a large amount of objects to be stirred ride up on the fan surface of the blade body, so that even if the fan surface is narrow, a large amount of objects to be stirred can be placed on the fan surface.

[0048] From the viewpoint of the role of each vane, it is preferable to increase the area of ​​the vanes that play more roles, as described below.

[0049] The first blade body 110 plays the role of fanning the objects to be stirred and of moving the objects to be scooped up to the subsequent second blade body 120. Here, the role of fanning the objects to be stirred is to scoop up the objects to be stirred and lift up and drop the scooped objects to be stirred, and is a role that is achieved by both the first and second actions of the blade body described above.

[0050] The second blade body 120 not only plays the role of fanning the material to be stirred and transferring the scooped material to the subsequent third blade body, but also plays the role of receiving the material to be stirred from the preceding first blade body 110.

[0051] The third blade body 130 has the role of fanning the material to be stirred and also the role of receiving the material to be stirred from the preceding second blade body 120, but does not have the role of transferring the scooped up material to the succeeding blade body.

[0052] From the perspective of the peripheral speed of the rotating container body 201, it is preferable that the relationship of the areas of the stirring surfaces of the three blade bodies is S3 < S2 < S1 gradually from the approximate center of the container body 201 toward the outer peripheral side. However, since the second blade body 120 undertakes more roles than the first blade body 110, for the blade body that undertakes many roles, in order to more surely fulfill its respective roles, specifically, in order to place more materials to be stirred on the stirring surface, it is preferable that the stirring surface area of the second blade body 120 is larger than that of the first blade body 110. As a result, for the first blade body 110, the second blade body 120, and the third blade body 130, the relationship of the areas of the stirring surfaces of these blade bodies is set to S3 < S1 < S2.

[0053] Hereinafter, the roles of each blade body will be described more specifically.

[0054] (The first blade body 110) First, the action undertaken by the first blade body 110 will be described.

[0055] (Stirring action) FIG. 3 is for explaining the state of scooping up the material to be stirred of the first blade body 110 shown in FIG. 2(a). In the state of stirring the material to be stirred in the container placed in a substantially horizontal state, it shows the state where the surface (stirring surface) 110b of the first blade body 110 has become substantially horizontal. Here, FIG. 3(a) is a perspective view, and FIG. 3(b) is a sectional view taken along line IIIa-IIIa of FIG. 3(a).

[0056] The first blade body 110 connected to the approximate tip of the shaft 10 of the stirring blade 100 is, in the state where the stirring blade 100 is attached to the blade support head 310 of the stirring device 300, as shown in FIG. 3, arranged at a position close to the center Bc of the bottom of the container body 201 of the container 200 in both the horizontal direction and the vertical direction of the container body 201.

[0057] 3, Rc indicates the rotation axis of the container 200, Rdc indicates the rotation direction of the container 200, and Rdf indicates the rotation direction of the stirring blade 100. Here, the height direction (approximately vertical direction) of the container 200 is the direction along the rotation axis Rc of the container 200, and the radial direction (approximately horizontal direction) of the container 200 is the direction perpendicular to the rotation axis Rc of the container 200.

[0058] The first blade body 110 is configured such that the blade tip 110a enters toward the inner surface of the container body 201 as the shaft rotates, and the end of the blade tip 110a connected to the shaft approaches the inner surface of the container first, and as the shaft rotates, the position of the blade tip that approaches the inner surface of the container moves to the opposite side from the side connected to the shaft, and when the end on the opposite side of the shaft approaches the inner surface of the container closest, the tilt surface 110b becomes approximately horizontal. In the present invention, the "tilt surface is approximately horizontal" state means that the inclination angle with respect to the horizontal state is within ±10°. The tilt surface is, for example, within ±10°, preferably within ±5°, and more preferably within ±2° with respect to the horizontal state. In the case of a stirred object that easily sticks to the inner surface of the container, such as vegetables, it is preferable to make the angle of the approximately horizontal state slightly larger to have the effect of scraping the stirred object off the inner surface of the container. In the case of a stirred object that does not easily stick to the inner surface of the container, such as rice or liquid, it is preferable to make it approximately horizontal as much as possible. In addition, it is preferable to adjust the horizontal state of the blades that scoop up the objects present on the outer periphery of the container, rather than the blades that scoop up the objects present in the center of the container. However, the present invention is not limited to this. The blades may be in a substantially horizontal state with the same angle.

[0059] The blade tip 110a of the first blade body 110 is approximately arc-shaped corresponding to the approximately arc-shaped inner surface of the container body 201. This allows the blade tip 110a to efficiently scoop up the object to be stirred when approaching the inner surface of the container. In a preferred embodiment, the blade body is configured to rotate in a state of zero-point contact with the inner surface of the container or in a non-contact state with a gap of approximately 20 mm or less (approximately 15 mm in one embodiment). By making the blade body non-contact with the inner surface of the container, it is possible to prevent the object to be stirred (especially foodstuffs such as rice) from being unnecessarily crushed during stirring. Here, if the gap between the blade body and the inner surface of the container is too wide, the object to be stirred cannot be reliably scooped up, and conversely, if it is too narrow, the object to be stirred may be unnecessarily crushed.

[0060] In FIG. 3, P1 is the height position of the tilt surface 110b of the first blade body 110 when the tilt surface 110b is approximately horizontal, and the height position P1 is based on the height position P0 of the center Bc of the bottom of the inner surface of the container body 201, and H1 is the height of the first blade body 110 from the reference position P0 when the tilt surface 110b of the first blade body 110 is approximately horizontal.

[0061] In this way, when the shaft rotates, the first blade body 110 first comes closest to the approximate center of the inner surface of the container 200, and the tilt surface 110b is greatly inclined. With subsequent rotation, the position of the cutting edge 110a closest to the inner surface of the container 200 gradually moves from the end connected to the shaft to the opposite side (corresponding to the outer periphery of the container 200), and the inclination of the tilt surface 110b becomes gentler. Then, when the end of the cutting edge 110a of the first blade body 110 opposite the connection part of the shaft comes closest to the container, the tilt surface 110b becomes approximately horizontal.

[0062] In this way, as the shaft rotates, the end of the blade tip 110a of the first blade body 110 connected to the shaft first comes closest to approximately the center of the inner surface of the container 200, and then the position closest to the inner surface of the container 200 gradually moves from the end connected to the shaft to the opposite side while making the inclination of the fan surface 110b gentler, making it easier to scoop up the object to be stirred with the fan surface 110b, and when the end opposite the connection part of the shaft is closest to the inner surface of the container 200, the fan surface 110b is kept in an approximately horizontal state, making it possible to more efficiently scoop up the object to be stirred with the fan surface 110b (first action).

[0063] Fig. 4 shows a schematic diagram of the object A1 scooped up by the first blade body 110 shown in Fig. 2 moving partially to the second blade body 120. Here, Fig. 4(a) is a side view, and Fig. 4(b) is a plan view showing the movement of the object A1 as seen from the Ax direction in Fig. 4(a).

[0064] As shown in FIG. 4(a), when the blade tip of the first blade body 110 approaches the inner surface of the container 200 due to the rotation of the shaft, the fan surface 110b, which was in a substantially horizontal state, gradually moves away from the inner surface of the container 200 to a higher position and becomes inclined from the substantially horizontal state due to further rotation of the shaft. As a result, the object A1 to be stirred that is scooped up on the fan surface 110b is lifted. Then, when the fan surface 110b is inclined at a predetermined angle or more, a part A12 of the object to be stirred falls from the fan surface 110b into the container 200, and another part of the part A12 of the object to be stirred moves to the blade tip surface 120b of the second blade body 120 connected via the first connecting member 20a.

[0065] In addition, as the shaft rotates, the fan surface 110b of the first blade body 110 gradually moves away from the inner surface of the container 200 to a higher position and becomes inclined from a substantially horizontal state, and at the same time, the second blade body 120 connected to the first blade body 110 by the first connecting member 20a gradually approaches the inner surface of the container 200 from the end of the fan surface 120b connected to the second connecting member 20a, and scoops up the object to be stirred in the container on the fan surface 120b of the second blade body 120. As a result, as shown in Figures 4(a) and 4(b), the object to be stirred A1 on the scooped fan surface 110b is lifted, and a part of it, A12, falls from the inclined fan surface 110b of the first blade body 110 into the container 200 (second action). Furthermore, the remaining part A11 of the object A1 moves onto the fan surface 120b of the second blade body 120 via the first connecting member 20a (moving action). Since the object A2 already scooped up by the second blade body 120 itself is present on the fan surface 120b of the second blade body 120, the object A11 that has moved from the first blade body 110 onto the second blade body 120 pushes out a part of the object A2 already on the second blade body 120. In this way, with the mixing blade 100, it is possible to move the object scooped up by the first blade body 110 onto the second blade body 120, which is different from the first blade body 110, and it is possible to expand the area to be stirred, and it is possible to mix more efficiently and uniformly.

[0066] (Second blade body 110) Next, the function of the second blade body 120 will be described.

[0067] Fig. 5 is a diagram for explaining the state of the second blade body 120 shown in Fig. 2(b) scooping up the object to be stirred, and shows the state in which the surface (fanning surface) 120b of the second blade body 120 is approximately horizontal in the state of stirring the object to be stirred in a container placed in an approximately horizontal state. Here, Fig. 5(a) is a perspective view, and Fig. 5(b) is a cross-sectional view taken along line Va-Va in Fig. 5(a).

[0068] The second blade body 120 is connected to the end of the first blade body 110 opposite to the end connected to the shaft 10 by the first connecting member 20a. When the mixing blade 100 is attached to the blade support head 310 of the mixing device 300, the second blade body 120 is located farther away from the center Bc of the bottom of the container body 201 of the container 200 than the first blade body 110 in both the horizontal and vertical directions of the container body 201, as shown in Fig. 5. In Fig. 5, the same reference numerals as in Fig. 3 indicate the same things as in Fig. 3. P2 is the height position of the tilt surface 120b of the second blade body 120 when the tilt surface 120b is approximately horizontal, and the height position P2 is based on the height position P0 of the center Bc of the bottom of the inner surface of the container body 201, and H2 is the height of the second blade body 120 from the reference position P0 when the tilt surface 120b of the second blade body 120 is approximately horizontal.

[0069] As with the first blade body 110, the second blade body 120 first comes closest to the inner surface of the container 200 at the end of the cutting edge 120a connected to the first connecting member 20a due to the rotation of the shaft, and in this state, the tilt surface 120b is greatly inclined. With subsequent rotation, the position of the cutting edge 120a closest to the inner surface of the container 200 gradually moves from the end connected to the first connecting member 20a to the opposite side (corresponding to the outer periphery of the container 200), and the inclination of the tilt surface 120b becomes gentler. Then, when the end of the cutting edge 120a of the second blade body 120 opposite to the first connecting member 20a comes closest to the container 200, the tilt surface 120b becomes approximately horizontal.

[0070] In this way, as the shaft rotates, the end of the blade tip 120a of the second blade body 120 connected to the first connecting member 20a first comes closest to approximately the center of the inner surface of the container 200, and then the position closest to the inner surface of the container 200 gradually moves from the end connected to the first connecting member 20a to the opposite side while making the inclination of the fan surface 120b gentler, making it easier to scoop up the object to be stirred with the fan surface 120b, and by keeping the fan surface 120b approximately horizontal when the end opposite the first connecting member 20a is closest to the inner surface of the container 200, the object to be stirred can be scooped up more efficiently with the fan surface 120b (first action). Furthermore, since the height at which the second blade body 120 approaches the inner surface of the container 200 differs from the height at which the first blade body 110 approaches the inner surface of the container 200, the area stirred by the first blade body 110 and the area stirred by the second blade body 120 differ, making it possible to stir more efficiently.

[0071] Figure 6 is a schematic diagram showing how the object to be stirred A11 moving from the first blade body 110 and the object to be stirred A2 scooped up by the second blade body 120 move partially to the third blade body, where Figure 6(a) is a side view and Figure 6(b) is a plan view showing the movement of the object to be stirred as viewed from the Ax direction of Figure 6(a).

[0072] The fan surface 120b of the second blade body 120 is configured to have the function of receiving the other part A11 of the object to be stirred A1 that has been scooped up by the fan surface 110b of the first blade body 110 as described above, and that has moved onto the fan surface 120b of the second blade body 120 via the first connecting member 20a.

[0073] As shown in Fig. 6(a) and Fig. 6(b), the object A11 sent from the first blade body 110 and the object A2 scooped up by the second blade body 110 are mixed together. This allows for uniform mixing. As the shaft further rotates, a part A22 of the object A20, which is a mixture of the object A2 and A11, moves the fan surface 120b, which was in a nearly horizontal state, away from the inner surface of the container 200 and to a higher position, and becomes inclined, as in the case of the first blade body 110. In addition, as the shaft rotates, the fan surface 120b of the second blade body 120 gradually moves away from the inner surface of the container 200 to a higher position and becomes inclined from a substantially horizontal state, and at the same time, the third blade body 130 connected to the second blade body 120 by the second connecting member 20b gradually approaches the inner surface of the container 200 from the end of the fan surface 130b connected to the second connecting member 20b, and scoops up the object to be stirred in the container on the fan surface 130b of the third blade body 130. As a result, as shown in Figures 6(a) and 6(b), the object to be stirred A20 on the scooped fan surface 120b is lifted, and a part of it A22 falls from the inclined fan surface 120b of the second blade body 120 into the container 200 (second action). Furthermore, the other part A21 of the object to be stirred A20 moves onto the fanning surface 130b of the third blade body 120 via the second connecting member 20b (moving action).

[0074] Furthermore, since the height at which the third blade body 130 approaches the inner surface of the container 200 is different from the height at which the second blade body 120 approaches the inner surface of the container 200, and since the area stirred by the second blade body 120 is different from the area stirred by the third blade body 130, more efficient stirring is possible.

[0075] (Third wing body 130) Next, the function of the third blade body 130 will be described.

[0076] (Incitement) Fig. 7 is a perspective view for explaining the scooping state of the third blade body 130 shown in Fig. 2(c), showing a state in which the surface (fanning surface) 130b of the third blade body 130 is horizontal. Here, Fig. 7(a) is a perspective view, and Fig. 7(b) is a cross-sectional view taken along line VIIa-VIIa in Fig. 7(a).

[0077] The third blade body 130 is connected to the end of the second blade body 120 opposite to the connection part with the first blade body 110 by the second connecting member 20b, and this third blade body 130 is disposed at the farthest position from the center Bc of the bottom of the container body 201 of the container 200 in both the horizontal and vertical directions of the container body 201 when the mixing blade 100 is attached to the blade support head 310a of the mixing device 300, as shown in FIG. 7. In FIG. 7, the same reference numerals as in FIG. 5 indicate the same as in FIG. 3. P3 is the height position of the tilt surface 130b of the third blade body 130 when the tilt surface 130b is horizontal, and the height position P3 is based on the height position P0 of the center Bc of the bottom of the inner surface of the container body 201. Moreover, H3 is the height of the third blade body 120 from the reference position P0 when the fan surface 130b of the third blade body 130 is horizontal.

[0078] The fan surface 130b of the third blade body 130 is a part of the object A20 present on the fan surface 120b of the second blade body 120 as described above, and is configured to have the function of receiving the object A21 that has moved onto the fan surface 130b of the third blade body 130 via the second connecting member 20b. The third blade body 130 is configured to perform the first and second functions by the rotation of the shaft, similar to the first and second blade bodies 110 and 120.

[0079] Furthermore, in this stirring device 300, the first driving means and the second driving means are configured so that the rotation speed per unit time when the blade driving means (first driving means) 310a included in the blade support head 310 rotates the stirring blade 100 and the rotation speed per unit time when the container driving means (second driving means) 320a included in the container support mechanism 320 rotates the container body 201 are different rotation speeds that have no common divisor other than 1. Here, the unit time is not particularly limited, but is, for example, the number of rotations per minute (rpm).

[0080] (Device housing 300a) Next, a specific example of the configuration of the device housing 300a shown in Fig. 1 and a specific example of the configuration of the head support mechanism that supports the blade support head 310 will be described. However, the specific configurations of the device housing 300a and the head support mechanism are not limited to the configurations described below and may be arbitrary.

[0081] FIG. 8 is a perspective view for explaining an agitation device 300 using the agitation blade 100 shown in FIG. 1(b).

[0082] The device housing 300a constituting this stirring device 300 has a base member 301 which is the base of the housing, a housing main body 302 provided on the base member 301 so as to form the side wall of the device housing 300a, and a housing top plate 303 which forms the upper surface of the device housing 300a, and a container receiving hole 303a which receives the bowl-shaped container main body 201 is formed in the housing top plate 303. The device housing 300a is provided with a heating means 350 for heating the container 200 so as to be located directly below the container receiving hole 303a. The specific configuration of the heating means 350 is not limited, and it may be a gas burner or an electromagnetic heating device.

[0083] Furthermore, shaft members 303b are attached to both ends of one side of the housing top plate 303, and these shaft members 303b are rotatably supported by bearing members 304 provided on the housing main body 302. This allows the housing top plate 303 to rotate relative to the housing main body 302 around the shaft members 303b.

[0084] Furthermore, other mechanisms and means provided on the base member 301 will be described in more detail.

[0085] Figure 9 is a plan view showing the structure of the stirring device 300 shown in Figure 8 when viewed from the Z direction (above), Figure 10 is a plan view showing the structure of the stirring device 300 shown in Figure 8 when viewed from the X direction (right side of the paper), and Figure 11 is a plan view showing the structure of the stirring device 300 shown in Figure 8 when viewed from the Y direction (front of the paper).

[0086] (Top plate driving means 340) As shown in FIGS. 8 to 11, the stirring device 300 includes a top plate driving means 340 for raising or lowering the casing top plate 303. As shown in FIG.

[0087] The top plate driving means 340 has a fixed bracket 341, a hydraulic cylinder 342, a bearing member 343, a fixed shaft 344, and an attachment bracket 345. Here, the fixed bracket 341 is fixed to the base member 301, and the attachment bracket 345 is attached to one end of the housing top plate 303. A fixed shaft 344 is fixed to the attachment bracket 345, and the fixed shaft 344 is rotatably supported by the bearing member 343, and a hydraulic cylinder 342 is attached between the fixed bracket 341 and the bearing member 343.

[0088] In this top plate driving means 340, by extending the rod of the hydraulic cylinder 342, the housing top plate 303, which is supported so as to be freely rotatable by the bearing member 304, is raised, and by contracting the rod of the hydraulic cylinder 342, the housing top plate 303 is tilted.

[0089] (Wing extension / retraction mechanism 330) The agitation device 300 includes a blade extending / retracting mechanism 330 that causes the agitation blade 100 to extend and retract into the container 200, as shown in FIGS.

[0090] The blade extending / retracting mechanism 330 has a head support means 330 a that supports the blade support head 310 that supports the agitating blade 100 so that the blade support head 310 can swing, and a head swinging means 330 b that swings the blade support head 310 .

[0091] 10 and 11, the head support means 330a has a head support stand 331, a shaft bearing 332, a rotating shaft 333, and a shaft fixing member 334. Here, the head support stand 331 is provided on the base member 301, and the shaft bearing 332 is attached to the upper end of the head support stand 331. Also, the rotating shaft 333 is fixed to the blade support head 310 by the shaft fixing member 334, and is rotatably supported by the shaft bearing 332 attached to the upper end of the head support stand 331.

[0092] 10 and 11, the head swinging means 330b has a fixed bracket 335, a hydraulic cylinder 336, a connecting bracket 337, and a head rotating arm 338. Here, the fixed bracket 335 is fixed to the base member 301, one end of the head rotating arm 338 is connected to the rotating shaft 333 of the head support means 330a, and the connecting bracket 337 is attached to the other end of the head rotating arm 338. A hydraulic cylinder 336 is attached between the connecting bracket 337 and the fixed bracket 341.

[0093] Thus, in the stirring device 300 of embodiment 1, the blade support head 310 is supported by head support means 330a so as to be rotatable relative to the head support base 331 around the rotation axis of the rotating shaft 333, and can be further swung by head swinging means 330b.

[0094] Therefore, in this stirring device 300, the stirring blade 100 supported by the blade support head 310 can be made to appear and disappear within the container 200 by swinging the blade support head 310 around the rotation axis of the horizontal rotation shaft 333.

[0095] In addition, in the stirring device 300, by raising the housing top plate 303 of the device housing 300a relative to the housing main body 302, the container 200 accommodated in the container accommodating hole 303a of the housing top plate 303 rises together with the housing top plate 303, and the stirred object A accommodated in the accommodating container 200 can be discharged all at once.

[0096] Next, the operation of the stirring device 300 will be described with reference to FIGS.

[0097] In the following description, the mixing device 300 is a cooking device that heats and stir-fries a plurality of ingredients that are the object to be mixed A. Therefore, the object to be mixed A is the ingredients for fried rice, specifically liquid egg (melted egg in a liquid form), cooked rice, onion, scallions, mixed seasoning liquid, green onion, etc.

[0098] First, the container 200 is rotated by the container driving means 320a (see FIG. 8) mounted on the container support mechanism 320, and then the mixed oil is poured into the container 200, and heating of the container 200 by the heating means 350 is started.

[0099] When the temperature of the container 200 reaches a temperature suitable for adding ingredients (for example, the container temperature is 190°C), the blade drive means 310a of the blade support head 310 starts to rotate the mixing blade 100, and liquid egg, cooked rice, onion, grilled meat, mixed seasoning, green onion, etc. are added in order suitable for the heating time according to the ingredients.

[0100] The operation of the agitating blade 100 agitating the object A will be described below.

[0101] As shown in Figures 3, 5, and 7, when container 200 containing at least one food ingredient A, rotates in rotation direction Rdc and mixing blade 100 rotates in rotation direction Rdf, each blade body 110, 120, 130 of mixing blade 100 sequentially enters toward the inner surface of container 200, and the fan surfaces 110b, 120b, 130b of each blade body 110, 120, 130 sequentially approach the inner surface of container 200, enabling each blade body 110, 120, 130 to scoop up the mixed object A.

[0102] Also, in each of the blade bodies 110, 120, and 130, when the respective blade tips 110a, 120a, and 130a sequentially come closest to the inner surface of the container body 201 of the container 200, the respective scooping surfaces 110b, 120b, and 130b assume a horizontal posture in sequence at height positions H1, H2, and H3 (H1 < H2 < H3) determined for each blade body, as shown in FIGS. 3, 5, and 7. This posture is a posture in which a large amount of the material A to be agitated can be placed on the scooping surfaces 110b, 120b, and 130b of each of the blade bodies 110, 120, and 130. With this posture, it is possible to efficiently scoop up the material A to be agitated. Further, since the heights at which each of the blade bodies 110, 120, and 130 come closest to the inner surface of the container 200 are different heights, it is possible to agitate the entire material A to be agitated in the container 200 and it is possible to efficiently and uniformly agitate it.

[0103] Thereafter, as the rotation of the stirring blade 100 progresses, the scooping surfaces 110b, 120b, and 130b of each of the blade bodies 110, 120, and 130 sequentially rise from a substantially horizontal state to an inclined state and move to a height away from the container 200.

[0104] Hereinafter, focusing on each individual blade body, the stirring operation by the blade body will be described.

[0105] In the first blade body 110, as shown in FIG. 4, after the blade tip 110a comes closest to the inner surface of the container body 201 and then the stirring blade 100 further rotates, as shown in FIG. 4(a), the first blade body 110 rises so that the scooping surface 110b approaches a posture perpendicular and parallel.

[0106] As the inclination of the fan surface 110b of the first blade body 110 becomes steeper with respect to the horizontal plane, the object A1 placed on the fan surface 110b of the first blade body 110 gradually slides down from the fan surface 110b. At this time, a part A12 of the object A1 falls from the first blade body 110 into the container body 201, but since the second blade body 120 is located below the first blade body 110, another part A11 of the object A1 moves to the second blade body 120 via the first connecting member 20a. The object to be stirred in the approximate center of the container 200 is scooped up by the first blade body 110, creating a space in the approximate center, and the object to be stirred that exists outside the center of the container 200 falls to the approximate center due to forces such as gravity.

[0107] At this time, the blade tip 120a of the second blade body 120 is approaching the inner surface of the container body 201, so that the object A2 to be stirred that has already been scooped up by the second blade body 120 is present on the fanning surface 120b of the second blade body 120. Therefore, in the second blade body 120, the object A11 to be stirred that has moved from the first blade body 110 and the object A2 to be stirred that has been scooped up by the second blade body 120 are both lifted up. In addition, in the second blade body 120, the object A2 that is already present is pushed by the object A11 to be stirred that has moved from the first blade body 110 and moves to the opposite side of the fanning surface 120b from the first blade body 110, and is gathered into one object A20 to be stirred. A portion of the material to be stirred that was approximately in the center of the container 200 and was scooped up by the first blade body 110 moves onto the fanning surface 120b of the second blade body 120, moving to the outer periphery of the approximately center of the container 200 and approximately in the radial center, thereby enabling more efficient stirring.

[0108] Thereafter, as the rotation of the agitator blade 100 continues, the blade tip 120a of the second blade body 120 approaches the inner surface of the container body 201 as shown in FIG. 5, and as the agitator blade 100 rotates further, the second blade body 120 rises so that the fan surface 120b approaches a vertically parallel position from a horizontally parallel position as shown in FIG. 6(a).

[0109] As the inclination of the fan surface 120b of the second blade body 120 becomes steeper with respect to the horizontal plane, the object A20 (A11+A2) placed on the fan surface 120b of the second blade body 120 gradually slides down from the fan surface 120b. At this time, a part A22 of the object A20 falls from the second blade body 110 into the container body 201, but since the third blade body 130 is located below the second blade body 120, the other part A21 of the object A20 moves to the third blade body 130 via the second connecting member 20b.

[0110] At this time, in the third blade body 130, the already present object A3 to be stirred is pushed by the object A21 moving from the second blade body 120, moves to the end of the fan surface 130b opposite the second blade body 120, and is gathered into a single object A30 to be stirred.

[0111] Thereafter, as the rotation of the agitator blade 100 continues, the blade tip portion 130a of the third blade body 130 approaches the inner surface of the container body 201 as shown in FIG. 7, and as the agitator blade 100 rotates further, the third blade body 130 rises so that the fan surface 130b approaches a vertically parallel position from a horizontally parallel position.

[0112] In this way, as the inclination of the fan surface 130b of the third blade body 130 becomes steeper with respect to the horizontal plane, the object A30 (A21) placed on the fan surface 130b of the third blade body 130 becomes steeper. +A3) gradually slides off the tilt surface 130b (see FIGS. 6(a) and 6(b)).

[0113] In this way, a part of the objects to be stirred present on the second blade body 120 (including the objects to be stirred at approximately the center of the container 200 scooped up by the first blade body 110) moves to the fanning surface 130b of the third blade body 130, and moves to the radially outer periphery of the container 200, making it possible to stir more efficiently. Note that, by scooping up the objects to be stirred at approximately the radial center of the container 200 by the second blade body 120, a space is created at approximately the radial center of the container 200, and the objects to be stirred present on the radially outer periphery of the container 200 fall into this space.

[0114] In this way, the object to be stirred at the approximate center of the container 200 scooped up by the first blade body 110 can move to the position of the second blade body 120 present at the approximate center of the radial direction of the container 200 and / or the position of the third blade body 130 present on the radial outer periphery side of the container 200, and the object to be stirred at the approximate center of the radial direction and / or the outer periphery side of the container 200 will fall sequentially into the cavity at the approximate center of the container 200 formed by the first blade body scooping up the object to be stirred. As a result, by stirring with the stirring blade of the present invention, the object to be stirred moves from the approximate center of the container 200 to the approximate center of the radial direction and / or the outer periphery side, and the object to be stirred present at the approximate center of the radial direction and / or the outer periphery side falls sequentially to the approximate center of the container 200, creating a circulation effect, which allows the object to be stirred more efficiently and uniformly. When the stirring of the object to be stirred A is completed, the object to be stirred A is discharged from the container 200.

[0115] Figures 12 and 13 are diagrams for explaining the operation of discharging the object to be stirred from the stirring device 300 shown in Figure 8, with Figure 12 showing a state in which the stirring blade 100 has been retracted from the container 200, and Figure 13 showing a state in which the container 200 has been raised upright relative to the device housing 300a of the stirring device 300.

[0116] When the stirring of the object A is completed, the stirring blade 100 is positioned inside the container 200, and in this state, the hydraulic cylinder 336 of the head rocking means 330b is driven so that its rod extends, causing the blade support head 310 to rotate around the rotating shaft 333. As a result, as shown in FIG. 12, the blade support head 310 lifts the stirring blade 100 from inside the container 200, and the stirring blade 100 is withdrawn from inside the container 200.

[0117] Next, in this state where the stirring blade 100 is retracted from inside the container 200, the hydraulic cylinder 342 of the top plate driving mechanism 340 is driven so that the rod extends. As a result, the housing top plate 303 rotates around the top plate shaft portion 303b, so that the container 200 is inclined obliquely together with the housing top plate 303, and the object to be stirred A contained in the container 200 is discharged from inside the container 200 to the outside.

[0118] In this manner, in the stirring device 300 of embodiment 1, the stirring object A, which is an ingredient placed in the container 200, is stirred by the rotation of the stirring blade 100 and the rotation of the container 200, and each blade body 110a, 120a, 130a stirs the stirred object A at a height position in the container body 201 corresponding to each blade body (i.e., vertical stirring by lifting and dropping), and at the same time, moves the stirred object A from the center to the periphery of the container body 201 (i.e., horizontal stirring by successively passing the stirred object A from the first blade body 110 to the third blade body 130).

[0119] Furthermore, in the stirring device 300 of this embodiment 1, the number of rotations per unit time of the stirring blade 100 (for example, the number of rotations per minute) and the number of rotations per unit time of the container 200 (for example, the number of rotations per minute) are different numbers of rotations that have no common denominator other than 1. Therefore, the frequency at which each of the blade bodies 110, 120, 130 comes closest to the same position on the inner surface of the container body 201 is only once per unit time. Therefore, within the container body 201, the stirring of the object to be stirred A by each blade body can be performed more uniformly even in the circumferential direction of the container 200.

[0120] In the stirring device 300 of this embodiment 1, the first blade body 110, the second blade body 120 and the third blade body 130 are such that the position P2 where the fan surface 120b of the second blade body 120 is approximately horizontal is higher than the position P1 where the fan surface 110b of the first blade body 110 is approximately horizontal, and the position P3 where the fan surface 130b of the third blade body 130 is approximately horizontal is higher than the position where the fan surface 120b of the second blade body 120 is approximately horizontal.

[0121] As a result, the locations where the stirring efficiency of each blade is highest are distributed in the height direction of the container, allowing more uniform stirring to be performed throughout the container.

[0122] In other words, the position in which the multiple blade bodies that make up the stirring blade can scoop up the most material when scooping up the material is a position in which the surface that scoops up the material is approximately horizontal.
