Description

  The present invention relates to a mixer mainly used at home, and more particularly to a mixer suitable for grinding beans such as soybeans.

  As is well known, in household mixers, foods such as vegetables and fruits in bottles are pulverized with a rotary cutter to produce a powdery or liquid fluid. Moreover, after adding liquids, such as water and milk, to the fluid in a bottle, stirring these and producing drinks, such as juice, is generally performed. As described above, when a liquid or drinkable product or the like (hereinafter simply referred to as “liquid product”) is prepared using a mixer, a part of the material to be pulverized is not sufficiently fined and is liquid as a so-called koji. It may remain in the object. In particular, when beans such as soybeans are pulverized by a mixer, it often occurs that these skins remain as cocoons without being finely pulverized. Therefore, in order to make the produced liquid material available in a state where the soot is separated, a mixer for separating the soot for filtering the liquid material has been conventionally provided in the mixer.

One of the mixers provided with a filter as described above is a mixer described in JP-T-2002-515272. This mixer includes a cylindrical filter, and the filter is detachably attached so as to surround the cutter in a container (bottle). By providing such a filter, when the produced liquid material is poured out of the container from the spout, the soot in the liquid material is stopped by the filter and the soot is removed from the liquid material.
JP-T 2002-515272

  Conventionally, such a filter is manufactured by welding a thin metal mesh material into a cylindrical shape. However, it is troublesome to produce a filter by such a method, which is one of the factors that increase the cost of the mixer. Furthermore, as a result of stirring in the mixer, bubbles are often generated in the produced liquid material, but in the conventional mixer, the bubbles flow out to the outside together with the liquid material. However, in most cases, such bubbles are not preferable for use or drinking of liquid materials, and it is required to be able to separate bubbles in addition to soot when taking out the liquid materials.

  A mixer with a filter that separates straw is often used in producing soymilk. For example, a process of pulverizing raw soybeans with a mixer is performed. At this time, if a large amount of raw soybeans is put into the bottle at one time, the cutter may not rotate. Therefore, alternately putting an appropriate amount of raw soybeans into the bottle and crushing them are repeated alternately. Preferably it is done. Therefore, in order to facilitate the pulverization of beans such as raw soybeans and similar foods, the mixer is required to be able to adjust the amount of foods put into the bottle to an appropriate amount.

  The present invention solves the above-described problems, and provides a mixer including a filter having a configuration that can be manufactured more easily and at a lower cost than conventional ones. The present invention also provides a mixer capable of taking out a liquid substance by separating bubbles in addition to the soot. Furthermore, the present invention provides a mixer having means capable of appropriately adjusting the amount of beans and similar foods to be added to the bottle.

The mixer of the present invention is a mixer comprising a cylindrical filter (5) that is detachably mounted so as to surround the cutter (41), wherein the filter (5) is a metal formed so as to have a filtering function. A thin plate member (54) formed of a holding member (55) formed of a flexible material and holding the plate member (54) in a cylindrical shape, the holding member (55) A first cylindrical part (56) arranged on the upper side, a second cylindrical part (57) arranged on the lower side, and a strip-shaped connecting part (58) connecting these cylindrical parts (56) (57).

The bottle (1) is formed in a substantially cylindrical shape, and a handle (10) is provided on the outside thereof. In this example and other examples described below, the bottle (1) is made of glass. However, in the present invention, the material of the bottle (1) is not necessarily glass, and an appropriate and usable material such as a transparent resin may be used.

  A resin lid (2) is detachably disposed on the upper side of the bottle (1) so as to close the opening. A cylindrical part (20) projects from the lower side of the lid (2). A plurality of protrusions (21) are formed on the outer peripheral surface of the cylindrical portion (20) at appropriate intervals around the circumference. The cylindrical part (20) of the lid (2) is elastically slightly deformed.When the cylindrical part (20) is inserted into the bottle (1), these protrusions (21) are formed in the bottle (1). By fitting in the groove formed on the peripheral surface, the lid (2) is stably attached to the bottle (1). A part of the upper end of the bottle (1) projects sideways and is not covered by the lid (2). In this way, an outlet (11) for discharging the liquid in the bottle (1) to the outside is provided. The outlet may be constituted by a plurality of slits provided in the lid (2).

  The bottle (1) is detachably attached to a bottle base (4) having a substantially frustoconical outer shape. When the bottle (1) and the bottle base (4) are combined, they are handled as a unit. A depression (40) is formed in the upper part of the bottle base (4), and the bottom surface of the depression (40) of the bottle base (4) functions as the bottom surface of the bottle (1). A screw thread (12) is formed on the outer surface of the lower part of the bottle (1), and a screw groove is formed on the inner wall of the bottle base (4) that forms the recess (40) .The lower part of the bottle (1) is the bottle base ( Screw into the recess (40) of 4). On the bottom surface of the recess (40) of the bottle base (4), a rotary cutter (41) having a plurality of blades and crushing food is arranged. The cutter (41) is screwed to the upper end of the shaft body (42) that protrudes upward through the bottom surface of the recess (40) of the bottle base (4). The shaft body (42) is rotatably supported inside the bottle base (4), and its lower end is connected to a coupling mechanism (not shown).

  The bottle base (4) is detachably mounted on the base (43). The base (43) includes an operation unit including a button (44) for instructing a pulverization process, a drive motor (not shown) for driving the cutter (41), a microcomputer for controlling various operations (not shown), and the like.

  In the mixer of the present invention, a substantially cylindrical filter (5) is detachably attached in the bottle (1) as necessary. The filter (5) is disposed so as to surround the cutter (41), and the food is put into the filter (5) and crushed. 2A is a side view of the filter (5), and FIG. 2B is a top view of the filter (5). The filter (5) includes a cylindrical portion (50) and an annular flange portion (51) formed at the lower end thereof. The filter (5) is made of metal, for example, stainless steel. Except for the lower part (52) of the filter (5) connected to the flange part (51), the majority (53) of the cylindrical part (50) is formed in a mesh shape, and the liquid can pass through the filter (5). However, the soot contained therein cannot pass through the filter (5). The most part (53) of the cylindrical part (50), in other words, the part (53) having a filtering function does not necessarily need to be formed in a mesh shape, and can pass a liquid or a liquid substance, etc. Any shape can be used as long as it can prevent the passage of ridges or granules having a large size. In the present invention, the range of the portion (53) having a filtering function is not particularly limited, and may be, for example, the entire cylindrical portion (50) or may be provided at a plurality of locations.

  As shown in FIG. 1, the flange portion (51) of the filter (5) is sandwiched between the lower end of the bottle (1) and the bottom surface of the hollow portion (40) of the bottle base (4), and the filter (5) Is fixed in the bottle (1). An annular first seal member (13) that contacts the upper surface of the flange portion (51) is joined to the lower end of the bottle (1), and the flange portion ( An annular second seal member (45) that contacts the lower surface of 51) is joined. For these seal members (13) and (45), for example, rubber packing is used. These sealing members (13) and (45) are in close contact with the flange portion (51), so that the liquid in the bottle (1) does not leak to the outside. If the filter (5) is not needed, rotate the bottle (1) to separate the bottle (1) from the bottle base (4), remove the filter (5), and then remove the bottle (1) from the bottle base (4 ). When the filter (5) is not attached, the first seal member (13) and the second seal member (45) are in direct contact with each other.

  By adopting the filter (5) mounting structure as described above, in the mixer of the present embodiment, the filter (5) is mounted in a stable state, and the filter (5) becomes hard during the operation of the mixer. There is no. As shown in FIG. 1, the height of the filter (5) is determined so that the upper end of the cylindrical part (50) of the filter (5) is separated from the lower surface of the lid (2) by an appropriate distance. preferable. This makes it possible to securely attach the lid (2) to the bottle (1) with the filter (5) attached, even when the bottle (1) has significant variations in dimensions. For example, the height of the filter (5) is set so that the lid (2) and the filter (5) do not come into contact with each other even when the height of the bottle (1) is the shortest within the range of dimensional variation of the bottle (1). Is determined.

  When manufacturing the filter (5) of 1st Example, the process of processing a thin plate-shaped metal material into a cylinder shape, and the process of joining a flange part (51) after that are required. In the mixer of the second embodiment, a filter (5) that can be easily manufactured without performing such a process is used. FIG. 3 is a side view showing the mixer with the filter (5) attached (partially broken). FIG. 4 is a side view of the filter (5) of the second embodiment. FIG. 5 is a view of the filter (5) broken along the horizontal plane including the line I-I shown in FIG. It is sectional drawing and the one part enlarged view. Similar to the first embodiment, the filter (5) of the second embodiment has a substantially cylindrical outer shape, and a flange portion (51) is provided at the lower end thereof. And the filter (5) of 2nd Example is attached in a bottle (1) similarly to 1st Example. However, unlike the first embodiment, the filter (5) of the second embodiment is manufactured by combining a thin plate material (54) having a filtering function and a holding member (55). The holding member (55) holds the plate (54) in a state of being bent into a cylindrical shape. For the plate material (54), for example, a stainless mesh material is used. The holding member (55) is formed of a resin having flexibility, and is formed by molding, for example, a polypropylene resin.

  On the left side of FIG. 6, the open plate (54) is shown. Moreover, the holding member (55) at the time of shaping | molding is shown by the right side of FIG. The plate material (54) is formed in a rectangular shape, and most of the plate material (54) is formed in a mesh shape (as partially shown in FIG. 6) except for its edge. In addition to such a mesh material, a member having a filtering function such as a punching metal may be used as the plate material (54).

  The holding member (55) includes a first cylindrical part (56), a second cylindrical part (57), and a strip-shaped connecting part (58) for connecting them. An annular groove (60) is formed in the first cylindrical portion (56) concentrically with the first cylindrical portion (56). A flange portion (51) is formed at one end of the first cylindrical portion (56). Similarly, a groove (61) is formed in the second cylindrical portion (57), and the diameter of the groove (61) is the same as the groove (60) of the first cylindrical portion (56). A plate material (54) bent into a cylindrical shape is inserted into the grooves (60) (61).

  One end of the connecting portion (58) is open to the end portion (62) of the first cylindrical portion (56) where the groove (60) is open, and the other end of the connecting portion (58) is open to the groove (61). Connected to the end portion (63) of the second cylindrical portion (57). On the end portions (62) and (63) side, a protrusion (64) is formed in the center of the connecting portion (58) along the longitudinal direction of the connecting portion. The length of the protrusion (64) is shorter than the length of the connecting portion (58), and both ends of the protrusion (64) are the end portions of the first and second cylindrical portions (56) and (57) ( 62) (63) has not been reached. As a result, both end portions of the connecting portion (58) are easily bent and function as a hinge mechanism for rotating the first cylindrical portion (56) or the second cylindrical portion (57). Further, two substantially rectangular protrusions (65a) (65b) (66a) (66b) are formed on both sides of the protrusion (64), and these protrusions ( Rectangular holes (67a) (67b) (68a) (68b) into which 65a) (65b) (66a) (66b) are respectively inserted are opened.

  The assembly process of the filter (5) will be described. 7A and 7B are explanatory diagrams showing this process. First, as shown in FIG. 7A, the plate member (54) is formed into a cylindrical shape, and the lower end portion of the plate member (54) is inserted into the groove (60) of the first cylindrical portion (56). The plate material (54) is arranged so that a gap between both side portions of the plate material (54) is positioned in the vicinity of the ridge (64). Next, as shown in FIG. 7B, the connecting portion (58) is bent, and the connecting portion (58) and the second cylindrical portion (57) are rotated upward. Then, the protrusion (64) of the connecting portion (58) is fitted into the gap between both side portions of the plate material (54), and the holding member (55) is inserted into the holes (67a) (67b) (68a) (68b) of the plate material. The projections (65a), (65b), (66a), and (66b) are respectively fitted (see FIG. 5). Thereafter, the connecting portion (58) is bent, the second cylindrical portion (57) is rotated downward, and the upper end of the plate (54) is inserted into the groove (61) of the second cylindrical portion (57). This completes the filter (5).

  As described above, since the filter (5) of the second embodiment can be manufactured without performing a joining process such as welding on the plate (54), the manufacturing time of the filter (5) is greatly reduced. The cost of the filter and thus the mixer is reduced. Further, in the second embodiment, the end portions of the metal plate (54) are all disposed in the holding member (55) and covered with the resin forming the holding member (55). (5) is configured very safely. For example, when handling the filter (5), the user does not cut his / her finger at the end.

  FIG. 8 is a side view of the mixer according to the third embodiment of the present invention (partially broken). One of the features of the mixer of the third embodiment is that a feeding device (7) suitable for feeding food, in particular beans and similar foods, into the bottle (1) is detachably provided. It is. The charging device (7) is disposed above the filter (5). 9A is a top view of the charging device (7), FIG. 9B is a bottom view of the charging device, and FIG. 9C is a view in which the charging device (7) is broken along the vertical plane including the line II-II shown in FIG. FIG. The dosing device (7) includes a side wall portion (70) formed in a bowl shape without a bottom and a bottom portion (71) covering the lower opening of the side wall portion (70). Four beams (72) arranged at intervals of about 90 degrees around the vertical axis extend inward from the inner surface of the side wall (70), and the ends of these beams (72) extend along the vertical direction. A substantially cylindrical sleeve (73) arranged in the manner described above is joined. The lower ends of the beam (72) and the sleeve (73) are located above the lower end of the side wall (70). The sleeve (73) holds the shaft (74) so as to be movable up and down, and the bottom (71) is screwed to the lower end of the shaft (74). A pressing member (75) to be pressed with a user's finger is fixed to the upper end of the shaft body (74).

  A flange (76) is formed on the upper portion of the shaft body (74), and an annular convex portion (77) surrounding the shaft body (74) is formed at the approximate center of the inner wall of the sleeve (73). Yes. A winding spring (78) as an urging member is disposed around the shaft body (74) between the flange (76) and the convex portion (77). The shaft body (74) is urged upward by the winding spring (78), and in a state where the pressing member (75) is not pressed, the peripheral portion of the bottom portion (71) is connected to the lower end surface of the side wall portion (70). It is in contact. When the pressing member (75) is pressed with a finger, the bottom (71) moves downward, and the lower opening of the side wall (70) is opened. When the finger is released from the pressing member (75), the bottom (71) moves upward and comes into contact with the lower end surface of the side wall (70) and stops. In this embodiment, a dish-shaped member inclined downward from the central portion toward the peripheral portion is used as the bottom portion (71), and a plurality of concave portions (79) recessed inward are provided on the peripheral portion. Is formed.

  In the third embodiment, a recess (22) is formed in the approximate center of the lid (2), and a cylindrically-shaped feeding device (7) is formed in the approximate center of the recess (22). An insertion hole (23) into which the lower part is inserted is formed (see FIG. 11). A plurality of ribs (80) project from the outer peripheral surface of the side wall (70) of the charging device (7) on the upper side of the lower part. In the present embodiment, a total of eight ribs (80) are provided at equal intervals. When the charging device (7) is inserted into the insertion hole (23), the lower ends of these ribs (80) abut against the bottom surface of the recess (22) of the lid (2), and the charging device (7) is stable. Mounted on the lid (2) in a state.

  As shown in FIG. 8, in the state where the lower opening of the charging device (7) is closed at the bottom (71), the foodstuff is put into the charging device (7) from the upper side. In FIG. 8, many beans (90) are shown as foodstuffs. By pushing the pushing member (75) with a finger, the bottom (71) moves downward, and the beans (90) are put into the bottle (1) as shown in FIG. In the present embodiment, since the lower opening of the dosing device (7) is disposed below the upper end of the filter (5), the food is reliably put into the filter (5). Also, as explained above, since the bottom (71) of the charging device (7) is inclined, the beans (90) are easy to fall into the bottle (1), and even a small amount of beans does not remain. Placed in bottle (1).

  The user can easily adjust the number or amount of beans (90) to be charged into the bottle (1) by attaching the charging device (7) to the lid (2). The number or amount of beans (90) charged at one time depends on the time when the lower opening of the charging device (7) is opened and / or the peripheral edge of the lower end surface and bottom (71) of the side wall (70). And changes depending on the distance. Therefore, the user appropriately adjusts the time for depressing the push member (75) and / or the distance for depressing the push member (75), and puts an appropriate or desired amount of beans (90) into the bottle (1). To do. As described above, a plurality of recesses (79) are formed on the peripheral edge of the bottom (71). These recesses (79) make it easier for beans (90) to pass between them even when the distance between the lower end surface of the side wall (70) and the peripheral edge of the bottom (71) is relatively short. A small amount of beans (90) can be smoothly put into the bottle (1).

  For example, when beans (90) are raw soybeans and soy milk is prepared using a mixer, as described above, after the appropriate amount of beans (90) is put into the bottle (1), the mixer Driven, the charged beans (90) are crushed. Thereafter, an appropriate amount of beans (90) is added again into the bottle (1) and crushed. The user repeats the charging and crushing of beans (90) until the desired amount of beans (90) is crushed. When a desired amount of beans (90) is pulverized, an appropriate amount of water is poured into the bottle (1) from the charging device (7) with respect to the powder of the produced beans (90). Thereafter, the mixer is driven, and the beans (90) powder and water are stirred. For example, 50 g of raw soybeans are pulverized by a mixer in 10 g portions, and 500 g of water is poured into the bottle (1) and stirred together with the produced soybean flour. After stirring, the produced liquid material is taken out of the mixer and put into a separately provided cup or the like. After that, the soymilk is completed by heating the liquid material with a microwave oven or the like.

  FIG. 11 is a side view showing the mixer in a state where the stirring is completed and the charging device (7) is removed (partially broken). The beans (90) are covered with skin, and even if the beans (90) are crushed, these skins do not become sufficiently fine. In addition, pieces of beans (90) that are not sufficiently fined may remain. Therefore, the liquid (91) produced by stirring the powder of beans (90) and water contains a large number of strawberries (92) that are the contents of the beans (90) and small pieces of skin. These bags (92) are stored in the filter (5).

After stirring, a large number of bubbles (93) are generated in the vicinity of the liquid surface of the liquid (91), and it is preferable that the bubbles (93) be removed when the bubbles (93) are transferred to a cup or the like. One of the features of the mixer of the present embodiment is that it includes a filter (5) having a function of separating the bubbles (93) from the liquid (91). The filter (5) has a configuration similar to that of the second embodiment, and includes a plate member (54) and a holding member (55) for holding it in a cylindrical shape. As in the second embodiment, the holding member (55) connects the first cylindrical portion (56) in which the flange portion (51) is formed to the second cylindrical portion (57) disposed on the upper side. And a connecting portion (58). The filter (5) is attached in the same manner as in the previous embodiment, and is disposed in the bottle (1).
