Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cooking device such as a food processor or a cooking mixer.

[0002]

[Prior art]

 In some cookers, the opening / closing switch that starts / stops the motor that rotates the cutter on the inner bottom of the bottle is turned on / off by the lid that covers the top opening of the bottle. This is known, for example, from Japanese Utility Model Publication No. 3-44119.

In the cooker described in this publication, an opening / closing switch is built in a standing portion having substantially the same height as the bottle provided on the cooker main body. The lid detachably attached to the bottle has a fitting tubular portion, and the tubular portion is fitted into the upper end opening of the bottle to close the upper end opening. The lid is integrally provided with a switch operating portion that projects outward in the radial direction, and a switch pressing projection is provided on the inner surface of the lid.

The switch operation portion covers the upper end of the upright portion when the lid is attached to the bottle, and the switch pressing protrusion is inserted into a hole opened in the upper end surface of the upright portion to cover the open / close switch. It comes into contact with the switch cover. Therefore, when the lid is pushed down by hand, the switch pressing projection pushes the open / close switch via the switch cover, and the open / close switch is turned on to operate the motor. Also, the open / close switch is a normally open type that is biased by a spring so that it is always in the off state. Therefore, by removing the force that pushes down the lid body, the lid body is opened by the force of the spring. As it is pushed up, the open / close switch is turned off, and the motor operation is stopped.

[0005]

[Problems to be solved by the device]

 In conventional cookers, there is no liquid-tight measure between the lid and the top opening of the bottle, so the liquid in the bottle may leak to the outside through the space between them. is there. By the way, there is known a cooking mixer in which a packing made of a rubber-like elastic body is provided on the outer periphery of the fitting cylinder portion of the lid. Therefore, liquid leakage can be prevented by attaching such packing to the fitting cylinder portion of the lid body that opens and closes the open / close switch.

However, since the lid of the conventional cooking device has a configuration in which the switch operating portion for performing the on / off operation of the open / close switch is integrally projected, if the packing is attached as described above, the open / close operation is performed. Not only the operation of turning on the switch becomes heavy, but also the large frictional force due to packing overcomes the force of the spring that pushes back the lid, so even if you release your hand from the lid in order to stop the cooking operation, opening and closing There is a problem that the switch cannot be turned off.

An object of the present invention is to provide a cooker capable of preventing liquid leakage from between a bottle and a lid and stopping the cooking operation arbitrarily through the lid.

[0008]

The rotary shaft 19 penetrates the bottom wall 16a in the vertical direction, and a driven coupling 20 housed in the base 16 is fixed to the lower end of the rotary shaft 19. This coupling 20 is formed by protruding a plurality of power transmission teeth on the lower surface of a disk-shaped base portion, and these teeth are driven by the drive coupling 7 when the bottle 15 is mounted on the bottle mounting wall 2. The couplings 7 and 20 are adapted to be rotated together through the engagement with the teeth of.

A cutter 21 made of a steel plate is fixed to the upper end of the rotary shaft 19 at the center in the longitudinal direction. The cutter 21 is arranged on the inner bottom portion of the bottle 15, and one end portion in the longitudinal direction thereof is bent obliquely downward, and the other end portion in the longitudinal direction is bent obliquely upward.

Ribs 22 are integrally provided at several locations on the inner surface of the cylindrical portion 17 of the bottle 15. These ribs 22 are formed so as to extend in the axial direction of the cylindrical portion 17 from the small diameter portion to the large diameter portion.

Reference numeral 23 in FIGS. 1 to 5 denotes a lid body which is detachably fitted and attached to the upper end opening of the bottle 15, which includes a lid body 24, a packing 25, a switch operation lever 26, and Is equipped with. The lid main body 24 made of synthetic resin has an annular flange 24a in contact with the upper end surface of the bottle 15 at the peripheral portion thereof, and is fitted into the upper end opening of the bottle 15 at a portion lower than the flange 24a. The fitting tubular portion 24b is formed. A packing 25 is attached to the outer periphery of the fitting tubular portion 24b.

The packing 25 is formed in a ring shape by a rubber-like elastic body. The packing 25 comes into contact with the inner peripheral surface of the upper end opening of the bottle 15 when the lid body 24 is attached to the bottle 15 to ensure liquid tightness between the bottle 15 and the lid 23. ing.

The lid main body 24 is provided with a groove 27 that is open to the upper surface and the peripheral surface of the lid main body 24 above the annular flange 24a. As shown in FIG. 3 and FIG. 4, the side walls 27a of the groove 27 which stand vertically and face each other are inclined so that they approach each other toward the rear end 27b of the groove 27. Bearing holes 28 as bearing portions are provided on the side of 27b.

As shown in FIGS. 6 and 7, the bearing hole 28 is formed of a circular hole main portion 28a and an auxiliary hole portion 28b provided so as to communicate with the main portion 28a. The auxiliary hole portion 28b has an arc shape drawn around the center of the hole main portion 28a. The upper portion of the auxiliary hole 28b is a through hole that penetrates the side wall 27a in the front and back, and the lower portion of the auxiliary hole 28b forms a guide 29. The guide 29 is formed as an inclined surface extending from the back surface of the side wall 27a to the front surface (the inner surface of the groove 27).

The switch operating lever 26 made of synthetic resin is attached to the lid body 24 so as to be vertically rotatable. More specifically, one end 26a of the switch operating lever 26 that fits into the groove 27 is tapered to match the shape of the groove 27, and both side walls 26b of the one end 26a are side walls 27a of the groove 27. Are formed in parallel with. A pivot 30 having a horizontal axis is integrally provided on the outer surface of each side wall 26b so as to project therefrom. As shown in FIG. 7, these pivots 30 are formed of a circular shaft portion 30a and a protrusion 30b integrally protruding from the outer periphery thereof, and each of the shaft portion 30a and a portion of the protrusion 30b. It has the slope 31 formed over.

In the switch operating lever 26, both shaft portions 30 a thereof are fitted into both hole main portions 28 a of the bearing holes 28, respectively, and both protrusions 30 b are through hole portions of both auxiliary hole portions 28 b of the bearing holes 28. , And is detachably pivoted to the lid body 24. The protruding portion 30b is smaller than the through hole portion of the auxiliary hole portion 28b, and the play between them causes the shaft portion 30a to rotate about the hole main portion 28a, that is, to rotate the switch operating lever 26 upward and downward. Movement is allowed.

To attach the switch operating lever 26 to the lid body 24, as shown in FIG. 4A, one end 26a of the switch operating lever 26 is directed toward the rear end 27b of the groove 27 (see FIG. 4A). Refer to the arrow). That is, when the leading end of the one end portion 26a of the switch operating lever 26 is brought closer to the inner end 27b of the groove 27 by this pushing, both pivot shafts 30 are guided to both side walls 27a, respectively, and these pivot shafts 30 are projected. At least one of the inclined both side walls 26b of the one end portion 26a and both side walls 27a of the groove 27 elastically deforms. The elastic deformation disappears when the pivots 30 are fitted into the bearing holes 28, respectively.

As a result, the pivot 30 is fitted into the bearing hole 28 in the positional relationship shown by the chain double-dashed line in FIG. 6, and the pulling in the direction opposite to the direction of the arrow shown in FIG. The switch operating lever 26 is attached so as not to come off against the tension. This mounting state is shown in FIG. 4 (B).

As described above, the switch operation lever 26 is attached to the lid main body 24 by a simple operation of inserting the tapered one end portion 26 a of the switch operation lever 26 toward the inner end 27 b of the concave groove 27. Can be installed.

As shown in FIG. 2, the free end portion 26c, which is the other end portion of the switch operating lever 26, is projected outward in the radial direction of the lid main body 24 and is bent downward, and the free end portion 26c is formed inside thereof. As shown in FIG. 1 and FIG. 5, the switch pressing portion 32 is integrally formed. The pressing portion 32 contacts the upper end 12a of the switch operating body 12, and when the lid 23 is attached to the bottle 15, the free end portion 26c side of the switch operating lever 26 is pushed downward, The opening / closing switch 11 can be closed via the switch operating body 12.

Next, a cooking procedure using the cooker having the above-described configuration will be described. First, into the bottle 15 placed on the bottle mounting wall 2 of the cooker main body 1, pour the material cut into an appropriate size and an appropriate amount of water as necessary, and then use the lid 23 to open the bottle. The upper end opening of the tor 15 is closed. At this time, the fitting tubular portion 24b is fitted into the bottle 15 until the annular flange portion 24a of the lid body 24 contacts the upper end of the bottle 15, and the fitting tubular portion 24b and the upper end opening portion of the bottle 15 are The packing 25 is sandwiched between itself and the peripheral surface with elastic deformation. Then, the switch operating lever 26 is pushed downward.

Then, the switch operating lever 26 is rotated about the bearing hole 28 and the pivot 30 in the clockwise direction in FIG. This rotation is allowed by the play between the through hole portion of the auxiliary hole portion 28b of the bearing hole 28 and the protrusion 30b of the pivot 30. Therefore, the switch pushing portion 32 of the switch operating lever 26 pushes down the switch operating shaft 12 against the spring force of the coil spring 14. Then, while the pressing continues, the open / close switch 11 is kept in the ON state and the motor 4 is operated.

Therefore, the power of the motor 4 is transmitted to the rotary shaft 19 through the engagement of both couplings 7 and 20, and the cutter 21 is rotated together with the rotary shaft 19, so that the inside of the bottle 15 is rotated. The material is cut by the cutter 21. Further, since it is not necessary to push down the lid main body 24 when the opening / closing switch 11 is turned on, there is no resistance due to the packing 25, and therefore the switch operating lever 26 can be pushed down easily.

In the cooking operation, the semi-liquid material by the cutter 21 is often moved to the lid 23 side. However, the packing 25 is sandwiched between the fitting cylindrical portion 24b of the lid 23 and the inner peripheral surface of the upper end opening of the bottle 15 with elastic deformation, so that liquid tightness between them is ensured. ing. Therefore, the semi-liquid material can be prevented from leaking to the outside of the bottle 15 through the space between the fitting tubular portion 24b and the inner peripheral surface of the upper end opening of the bottle 15.

Then, according to the judgment of the user who looks through the inside of the bottle 15 in the cooking operation, when the cooking operation is stopped, it is only necessary to remove the hand from the lid body 23. Then, the spring force of the coil spring 14 pushes the free end portion 26c side of the switch operating lever 26 upward through the switch operating shaft 12, so that the switch operating lever 26 is centered around the bearing hole 28 and the pivot 30. 1 It is rotated counterclockwise in the middle. Therefore, the opening / closing switch 11 is turned off and the operation of the motor 4 is stopped.

In such a stop operation of the cooking operation, the switch operating lever 26 is rotatably attached to the lid body 24 as described above, and therefore the lid body 24 is pushed back by the spring force of the coil spring 14. No need. Therefore, the frictional force of the packing 25 sandwiched between the fitting tubular portion 24b and the inner peripheral surface of the upper end opening of the bottle 15 does not load the coil spring 14, and the coil spring 14 is switched. Only the lever 26 and the switch operating body 12 are loaded. Therefore, the cooking operation can be stopped easily and arbitrarily.

Further, the lid 23 can be disassembled after use. That is, as shown in FIG. 1, when the one end portion 26a of the switch operating lever 26 is accommodated in the concave groove 27 of the lid main body 24 and the switch operating lever 26 is pivoted so as to be largely pulled counterclockwise, 5. At the stage shown by the solid line, the protrusion 30b of the pivot 30 engages with the upper end 29a (see FIG. 7) of the guide 29 of the auxiliary hole 28b in the bearing hole 28. In this case, the slope 31 provided on the pivot 30 engages the guide 29.

Therefore, by further continuing the counterclockwise rotation of the switch operating lever 26, the pivot 30 is pushed inward in the groove 26 along the slope of the guide 29, and the two points in FIG. When the pivot 30 is rotated upward to the angle shown by the chain line, the pivot 30 reaches the lower end 29b (see FIG. 7) of the guide 29 and comes out of the bearing hole 28. Therefore, the switch operating lever 26 is separated from the lid body 24.

In this way, the lid body 24 of the lid body 23 and the switch operating lever 26 can be easily disassembled, so that it is possible to wash the corners of the lid body 23 as a single product and to keep the lid body 23 hygienic. Moreover, since it can be disassembled with the counterclockwise rotation as described above, when an excessive external force for rotating the switch operating lever 26 in the counterclockwise direction is applied during handling, the switch operating lever 26 and the lid main body 24 can be handled. And can be disassembled to prevent their damage.

8 and 9 show a structure in which the lever 26 is automatically separated from the lid main body 24 by largely rotating the switch operating lever 26 counterclockwise in the one embodiment. The configuration or the configuration shown in FIGS. 10 to 12 may be adopted.

In FIGS. 8 and 9, both side walls 26d of the switch operating lever 26 are provided in parallel with each other, and a pivot 30d integrally formed on the outer surface of the switch operating lever 26 is formed of a hemispherical projection. Both side walls 27d of the groove 27 of the lid main body 24 are parallel to both side walls 26d of the lever 26, and bearing holes (bearing portions) 28d provided in these walls 27d are circular holes. A pivot 30d is detachably fitted in the hole 28d.

The end surfaces 26e of the both side walls 26d of the switch operating lever 26 are formed as arcuate surfaces, and the end surfaces 26e are brought into contact with and separated from the inner corners formed by the inner wall and the bottom wall of the concave groove 27. 27e is formed. The guide 27e is formed by a wall having a slope or a similar curved surface. The distances A to C between the bearing hole 28d and the inner wall of the recessed groove 27, the guide 27e, and the bottom wall relative to the bearing hole 28d are determined to satisfy the relation of A> B> C.

In such a mounting structure of the switch operating lever 26, when the lever 26 is largely rotated in the counterclockwise direction, the end surface 26e of the switch operating lever 26 first comes into contact with the guide 27e and then the concave groove. Since it contacts the bottom wall of the switch 27, the contact pressure of the lever 26 to the groove 27 is gradually increased and the switch operating lever 26 is pushed up. Therefore, the shaft 30d naturally comes out of the bearing portion 28d along with the elastic deformation of both side walls 26d of the switch operating lever 26, and the lid body 24 of the lid 23 and the switch operating lever 26 can be disassembled.

10 to 12 as in the configurations of FIGS. 8 and 9, both side walls 26d of the switch operating lever 26 are provided in parallel with each other, and a pivot 30d is integrally provided on the outer surface thereof as a unit. Has been done. Both side walls 27d of the groove 27 of the lid main body 24 are parallel to both side walls 26d of the lever 26, and bearing holes (bearing portions) 28d provided in these walls 27d are circular holes. A pivot 30d is detachably fitted to 28d. The end faces 26e of the both side walls 26d of the switch operating lever 26 are formed as arcuate faces, and guides 27g for contacting and separating the end faces 26e are formed at the corners on both sides formed by the side wall and the bottom wall of the groove 27, respectively. ing. The guide 27g is formed by a wall having a slope or a similar curved surface.

Even in such a mounting structure of the switch operation lever 26, when the lever 26 is largely rotated counterclockwise, the end surface 26e of the switch operation lever 26 in the state of FIG. First, as shown in FIG. 12 (B), since the guides 27g of the concave groove 27 are in contact with each other, the contact pressures thereof gradually increase and the switch operating lever 26 is pushed up, while the side walls 26 of the switch operating lever 26 are pushed up. Are elastically deformed so that they approach each other. Therefore, the pivot 30d naturally comes out of the bearing hole 28d, and the lid body 24 of the lid 23 and the switch operating lever 26 can be disassembled as shown in FIG. 12C. Note that in FIG. 12, the lid main body 24 shows a cross section taken along the line WW in FIG. 11, and the switch operating lever 26 shows a cross section taken along the line VV in FIG.

Further, the present invention is not limited to the above-mentioned embodiment. For example, when the switch operating lever 26 of the lid body 24 is attached, the bearings formed of holes or holes may be provided on both side walls 26b of the switch operating lever 26, and the pivots may be provided on both side walls 27a of the concave groove 27. . Further, the opening / closing switch 14 may be arranged at the upper end of the standing portion 3. The present invention can also be applied to a cooker in which the bottle 15 is formed integrally with the cooker main body 1.
