Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mixer for cooking an object to be cooked in a container by rotating a cutting means. 2. Description of the Related Art Conventionally, a cutting / stirring cutter located in a container placed on an upper part of a main body and rotationally driven by an electric motor in the main body is provided, and the cutting / stirring cutter is rotated by operating a switch for controlling operation of the electric motor. 2. Description of the Related Art A mixer as an electric cooker for cooking an object to be cooked in a container is known. From the rear end of the mixer, for example, a power cord extends out of the main body, and when the mixer is not used, the power cord is bundled so as not to obstruct it, but the bundled part is exposed outside the main body. It was still the case, and it was inevitable that it would bother you as well as look bad. Therefore, it is conceivable to store the power cord in the main body. In this case, the power cord is stored in a case in a state where the power cord is wound in a layered form to form a code reel unit, and stored in the main body, so that the power cord can be easily used without being exposed outside the main body. It can be worn with good appearance. The power cord in the cord reel unit is located at the outermost periphery at one end to which the insertion plug is attached, and at the approximate center of the case at the other end having the connection terminal connected to the electric motor at the innermost periphery. The connection terminal is exposed at a substantially central portion on one outer surface of the case. By the way, when the code reel unit is stored in the main body, the arrangement of the electric motor which can be installed in the up and down direction extends the entire mixer in the up and down direction, so that the center of gravity becomes high and the stability is inferior. It is desirable to arrange on the side that is around the electric motor. However, when the motor is disposed on the side of the electric motor, the lateral width of the main body increases in the lateral direction of the main body, so that the longitudinal direction of the main body is relatively shortened. There is a problem in that the switch located on the front surface and pressed in the front-rear direction may become unstable when operated. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object the purpose of forming a power cord into a cord reel unit and arranging the power cord in a position where the front-rear direction of the main body is enlarged, thereby stabilizing the operation of the switch. It is to provide a mixer that brings. Means for Solving the Problems In order to achieve the above object, a mixer according to the present invention includes a cutting unit rotatably driven by an electric motor in the main body in a container placed on an upper part of the main body, In a mixer for cooking an object to be cooked in the container by rotating the cutting means by operating a switch for controlling the operation of an electric motor , a central part in a lateral direction of a switch unit provided with the switch ;

The main body is arranged so as to coincide with the center of the main body in the width direction . In the mixer according to the present invention, at the time of cooking, the power cord is pulled out from the cord reel unit in the main body, the object to be cooked is put in the container mounted on the main body, and the switch is operated to drive the electric motor. By the driving of the electric motor, the cutting means rotates and the object to be cooked in the container is cooked. At the end of cooking, the power cord is wound up around the cord reel unit and stored in the main body. Also, the center of the switch unit in the width direction and the center of the motor in the width direction are
When the center of the code reel unit in the width direction is aligned with the front-rear direction of the main body,
Both are arranged so as to coincide with the center of the main body in the width direction.
The machine is heavy and the code reel unit is relatively heavy. In addition, toned
The main body, in which the container holding the material is placed above the motor, is also heavy.
The center of gravity of the mixer and the center of the switch unit in the width direction
Can be matched in direction. Therefore, the direction in which the switch is pressed depends on the weight of the mixer.
When the switch is pressed, the mixer moves around the center of gravity.
The rotation prevents the direction from changing, and the mixer when operating the switch
Can be stabilized. Hereinafter, embodiments of a mixer according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, a mixer 10 as an electric cooker has a main body case 11 and a container 12 mounted on an upper surface of the main body case 11.

As shown in FIGS. 6 and 7, the lower case 14 is formed in a dish shape, and has four legs 29 located at substantially four corners and one leg 30 located at the rear end on the bottom outer surface. In addition, a plurality of ventilation holes 31 penetrating the bottom front and rear surfaces are formed at the bottom front end and substantially at the center of the bottom, and a power cord 46 to be described later is inserted and removed at the bottom rear end corner. It has a recess 33 in which an opening 32 is formed. Note that each leg 29 is located on the back side of each boss 35 described later, and rubber feet 29a for preventing slip are embedded in the two front legs 29. On the inner surface 14a side of the lower case 14, two ribs 34 are provided at positions corresponding to the two ribs 23 when combined with the upper case 13, and four bosses 35 are similarly provided at positions corresponding to the four bosses 27. In the vicinity of the recess 33, a pair of ribs 36 facing each other with a thickness separation of the code reel unit 17 are formed. The switch unit 15 is installed on the rear surface side of the inclined surface 18 with the mounting plate 15 a sandwiched between two sets of ribs 23 and 24, and the upper portion is inserted into the flange 22 on the rear surface 21 side of the upper surface 19. A motor 16 is provided (see FIGS. 1 and 5). The switch unit 15 has three switch knobs 37a, 37b, and 37c that are arranged in parallel above the mounting plate 15a and that control the operation of the motor 16 (FIG. 1).
, 2) The switch knobs 37a and 37c are constantly urged to be protruded by urging means such as a coil spring so as to be freely pressed. Powered by The switch knob 37a performs a flash (intermittent) operation of operating the motor 16 only when pressed, the switch knob 37b performs a continuous operation of operating the motor 16 in the pressed state, and the switch knob 37c operates by pressing the switch. The operation of the motor 16 is stopped with the 37b protruding. As shown in FIG. 8, the motor 16 has a drive shaft 39 located at the center of the longitudinal axis and included in the field assembly 38. The field assembly 38 is moved from both upper and lower sides by an upper frame 40 and a lower frame 41. It is pinched. The upper frame 40 is formed in a cap shape from a heat-resistant resin, which is a heat-resistant member having a low thermal conductivity.
(See FIG. 1). On the outer peripheral edge of the upper frame 40, two screw holes 42 are formed which are open on the upper surface 40a and are located at the diameter positions of the upper surface 40a. A hole (not shown) is formed. The lower frame 41 is formed in a frame shape whose both sides are open, and has a lower surface 41a.
The lower shaft of the motor 16 is formed by rotatably holding the drive shaft 39 at the center (
(See FIG. 1). On the side of the lower frame 41, two screw holes 43 that are open to the lower surface 41a and that communicate with the screw holes 42 are formed. The motor 16 is configured such that the upper frame 40 and the lower frame 41 sandwich the field assembly 38 by inserting the boss 28 into the screw hole 42 and screwing the screw S inserted from the screw hole 43 into the boss 28. Is formed and at the same time
9 is fixed to the upper case 13 with a gap a between the rear surface 21 and the upper portion of the upper frame 40 inserted into the flange 22 (see FIG. 8). As shown in FIG. 9, the code reel unit 17 is formed in a slightly thick disk shape in which the upper opening of the lower cover 45 is closed by the upper cover 44, and the power cord 46 is rotated by a rotating unit (not shown). The lower cover 45 is wound horizontally in a layer so that it can be pulled out or wound up (see (a)). One end of the power cord 46 is connected to a pair of power supply terminals 47 protruding from the center outer surface of the upper cover 44, and the other end is connected to a plug 46 a exposed from the outlet 17 a of the cord reel unit 17. Connected (see (b)). An urging member (not shown) such as a mainspring for urging the power cord 46 in the winding direction is provided in the cord reel unit 17, and a rotating unit is stopped or rotated when the power cord 46 is pulled out or wound. An automatic winding mechanism including an operation control member (not shown) for performing the operation is provided. With this automatic winding mechanism, the cord reel unit 17
When the drawer is pulled out, if the drawer is stopped, it stops without returning, and if it is pulled out next, it is wound up without stopping, and this stop or winding operation can be repeated sequentially. Therefore, when the mixer 10 is used, the power cord 46 can be extended by an arbitrary length by pulling the power cord 46 from the outlet 17a with the insertion plug 46a exposed outside the cord reel unit 17, and the mixer 10 cannot be used. In use, the power cord 46 can be automatically wound into the cord reel unit 17. The code reel unit 17 holds the upper cover 44, which is the outer surface on which the pair of power supply terminals 47 are provided, by holding the pair of ribs 25 between the thickness direction and the pair of ribs 26 in the width direction. It is located on the rear end side of the upper case 13, which is the opposite side, and is disposed and fixed vertically behind the motor 16 (FIG. 1, FIG.
5). By arranging the pair of power supply terminals 47 on the opposite side of the motor 16, the distance between the cord reel unit 17 and the motor 16 can be secured to secure an insulation distance from the motor 16 and a space for leading the lead wire L. There is no need to keep a certain distance,
The code reel unit 17 can be arranged close to the motor 16 (see FIG. 5). The inclined surface 18 has three elliptical openings 48 that are opened side by side to project the switch knobs 37a, 37b, and 37c, respectively (see FIGS. 2 and 3). The mounting portion 20 has a circular opening 49 at the center of the upper surface 19, on the periphery of which a step portion 49a is protruded. Inside the upper surface 19 at a distance from the periphery, the mounting portion 20 is provided along the periphery and at regular intervals. Thus, six engaging claws 50 are protruded. Further, on the periphery of the upper surface 19, three square bar-shaped base portions 51 a and three cylindrical base portions 51 b are alternately protruded on the outer side of the engagement claws 50 and located between the adjacent engagement claws 50. (See FIGS. 2 and 3). The drive shaft 39 of the motor 16 is positioned substantially at the center of the opening 49 with its upper end protruding from above the step portion 49a (see FIGS. 1 and 8). Then, the upper case 13 and the lower case 14 are combined vertically and the screws inserted into the bosses 35 from the legs 29 are screwed to the bosses 27, so that the bottom opening of the upper case 13 is closed and the main body case 11 is closed. The ribs 23 and the ribs 3
4, the switch unit 15 is clamped and fixed. Further, a cord reel unit 17 having an upper end portion clamped and fixed to both ribs 25 and 26.
Is fixed to the rib 36 and the inner surface 14a of the lower case 14 so that the code reel unit 17 is disposed in a vertical position behind the motor 16 (FIGS. 1, 5). reference). Therefore, the switch unit 15 and the code reel unit 17 are located back and forth with the motor 16 interposed therebetween, and the center of the switch unit 15 in the lateral width direction is opposed to the inclined surface 18 on the front side of the main body case 11. And the center of the motor 16 in the width direction and the center of the code reel unit 17 in the width direction,
1 is located on the center line in the width direction. That is, the switch knobs 37a, 37b, and 37c, the motor 16, and the code reel unit 17 installed in a vertical position are arranged in a line in the front-rear direction of the main body case 11 (see FIG. 5). At this time, the insertion plug 46a protruding from the outlet 17a of the code reel unit 17 passes through the opening 32 of the lower case 14 and is positioned in the recess 33 located at the rear end corner of the main body case 11. The drive coupling 5 is provided at the upper end of the drive shaft 39 projecting from the upper surface of the main body case 11.
2 are detachably screwed into the drive coupling 52. A plurality of engagement projections 52a are provided on the upper surface of the disk and a plurality of blower blades 52b are radially provided on the lower surface of the drive coupling 52 (see FIG. 1). The container 12 is mounted on the mounting portion 20. The container 12 includes a cylindrical container body 53 having an upper end 53a and a lower end 53b opened,
And a cylindrical bottle support 54 attached to the lower part of the container body 53 (see FIGS. 1 and 2). The container main body 53 has a handle 55 formed on the side and a lid 56 for closing the opening of the upper end 53a. The container main body 53 is connected to the bottle support 54 via a screw portion 57 formed on the outer peripheral surface of the lower end 53b. Removably attached. The bottle support 54 has a partition wall 58 formed by partitioning the inside of the cylinder up and down, and an inner peripheral wall 54b protruding from a lower surface of the partition wall 58 so as to be separated from the outer peripheral wall 54a.
have. A screw portion 59 is formed on the upper inner surface of the outer peripheral wall 54a. On the partition wall 58, a stepped portion 58a is formed on the peripheral edge of the upper surface, and a rotating shaft 60 that penetrates the front and back surfaces is mounted inside the adjustment liner 60a and is rotatably mounted. A rubber ring 61 is attached to the step 58a, and a cutter 62 is attached to the upper part of the rotating shaft 60, and a driven coupling 63 is attached to the lower part (see FIG. 1). As shown in FIG. 10, the cutter 62 has a cutting and stirring blade 64 and a crushing blade 65 that are vertically separated from each other. With 65, the food can be crushed ((a), see FIG. 1). The cutting agitating blade 63 and the crushing blade 64 are arranged so that the respective blade portions 64a and 65a are orthogonal to each other (see (b)). The driven coupling 63 is formed in a disk shape with a plurality of engaging projections 63a radially protruding from the lower surface (see FIG. 1). The screw portion 59 is screwed into the screw portion 57, and the bottle support 54 is integrally attached to the container body 53.
And the opening at the lower end 53 b is closed by the bottle support 54 via the rubber ring 61, and the bottle 62 has a cutter 62 located at the lower portion inside the container body 53. Further, the bottle support 54 integrated with the container main body 53 is mounted on the upper surface 19 of the mounting portion 20 by fitting the engagement claw 50 into the engagement state on the outer side of the inner peripheral wall 54b, thereby placing the engagement protrusion 52a. And the engagement protrusion 63a is engaged, and the drive coupling 52 and the driven coupling 63 are connected in an engaged state (see FIG. 1). Accordingly, the rotation of the motor 16 is transmitted from the drive coupling 52 to the driven coupling 63 via the drive shaft 39, and rotates the cutter 62. At this time, the bottle support 54 placed on the upper surface 19 is attached to both the bases 51a and 51b.
As a result, a gap is formed between the lower end 54c and the upper surface 19, and the rotation of the blower blade 52b due to the rotation of the drive coupling 52 causes the blower for cooling the motor 16 sent out of the gap to the outside of the upper case 13. A path is formed. In other words, the blower blades 52b rotate to discharge the air in the gap a, so that the air enters through the vent holes 31 of the lower case 14, passes through the field assembly 38 from the lower frame 41 of the motor 16, and passes through the through holes of the upper frame 40. Then, a ventilation path is formed that reaches the gap a between the upper frame 40 and the back surface 21 and that escapes from the opening 49 to the outside of the main body case 11 through the gap between the lower end portion 54 c and the upper surface 19. Note that a small cup 65 can be detachably attached to the bottle support 54 instead of the container body 53. The cup 65 has a screw portion 57 similar to that of the container body 53 formed on the outer peripheral surface of the upper opening. By turning the screw portion 57 upside down and screwing the screw portion 57 to the screw portion 59, the cutter 65 is positioned above the bottle support 54. A closed space having the bottom as the partition 58 on which the protrusion 62 is provided is formed (see FIG. 1). Next, the operation of the mixer having the above configuration will be described. First, the mixer 10 is placed on a table or the like, and the power cord 46 is pulled out from the cord reel unit 17 by a required length with the insertion plug 46a exposed from the recess 33 of the lower case 14. By stopping the drawer, the power cord 46 stops in the pulled-out state without returning, so the insertion plug 46a is connected to the power outlet. By connecting the plug 46a to a power outlet, the motor 16 can be energized. Subsequently, by integrally mounting the bottle support 54 to the container body 53,
With the cutter 62 positioned at the lower portion inside the container body 53, the container 12
Is mounted on the mounting portion 20 of the main body case 11. After the object to be cooked is put in the container 12 attached to the main body case 11, the lid 56 is closed,
By operating the switch knobs 37a and 37b, the motor 16 is driven. When the motor 16 is driven, the cutter 62 rotates, and the object to be cooked in the container 12 is stirred and cut and crushed, and is cooked. At the time of cooking, depending on the cooking method, a flash (
(Intermittent) operation or continuous operation by the switch knob 37b. The continuous operation can be stopped by the switch knob 37c. At the end of cooking, the power cord 46 is pulled out by pulling out the plug 46a.
Is wound around the code reel unit 17 without stopping. By the way, the code reel unit 17 is arranged vertically behind the motor 16 with the pair of power supply terminals 47 positioned on the opposite side of the motor 16 side.
It is not necessary to secure an insulation distance from the motor 16 and a space for leading the lead wire L, and the device can be arranged close to the motor 16. Accordingly, since the power supply cord 46 is formed into a code reel unit and stored in the main body case 11 and the main body case 11 can be reduced in size, a large space is not required for installation and storage, and the cost can be reduced. Becomes In particular, the switch unit 15, the motor 16 and the code reel unit 17
By being arranged in a line in the front-rear direction of the main body case 11, it is possible to make the depth dimension of the front and rear of the main body case 11 larger than the lateral width dimension of the main body case 11,
A switch knob 37a located on the front surface of the main body case 11 and operated by pressing in the front-rear direction.
, 37b and 37c can be enhanced in the sense of stability during operation. Further, the center of the switch unit 15 in the width direction and the center of the motor 16 in the width direction are set.
The center and the center of the code reel unit 17 in the width direction are the width of the main body case 11.
Are arranged so as to be located on the center line in the direction, and the motor 16
Are heavy, and the code reel unit 17 is also relatively heavy. In addition,
The main body case 11 in which the container 12 containing the food is placed above the motor 16 is also heavy.
The position of the center of gravity of the mixer 10 and the switch unit 1
5 can be made to coincide with the center in the width direction in the front-rear direction. Because of this,
The direction in which the push knobs 37a to 37c are pushed is the direction of the center of gravity of the mixer 10, and
When the push knobs 37a to 37c are pressed, the mixer 10 rotates around the center of gravity.
Thus, it is possible to prevent the direction from being changed, and to stabilize the mixer 10 when the switch is operated . Also, placed at the end of the switch unit 15
When the switch knobs 37a and 37c are operated, the position of the center of gravity of the mixer 10 is maintained.
And the center of the switch unit 15 in the width direction can be matched.
Thus, the direction in which the switch knobs 37a and 37c are pushed is larger than the position of the center of gravity of the mixer 10.
The mixer 10 rotates around the position of the center of gravity.
Is prevented. In order to enhance the sense of stability when operating the switch knobs 37a, 37b and 37c, rubber feet 29a for preventing slippage are embedded in the two front legs 29. By increasing the front and rear depth dimensions, the pressing direction at the time of operating the switch is located between the front and rear legs 29, and the front legs 2
Since the downward turning force acts on the rim 9, slip prevention can be effectively performed only by providing the rubber foot 29a only on the front leg 29. Further, the motor 16 is fixed to the flange 22 with the upper portion of the upper frame 40 inserted therein, and the upper frame 40 formed of a heat-resistant resin is interposed between the motor 16 and the upper case 13. It becomes difficult for the heat generated by the field assembly 38, which is a heating element, to be transmitted to the upper case 13. Therefore, thermal deformation of the upper case 13 projecting the drive shaft 39 from the opening 49 does not occur, and the center of the driven coupling 63 of the bottle support 54 mounted on the upper surface 19 and the center of the drive coupling 52 of the drive shaft 39. Does not occur. In addition, since it is not necessary to take measures against heat of the upper case 13, it is not necessary to use a heat-resistant resin for the upper case 13 and a cheaper general material can be used. The degree of freedom in design is not narrowed, and the size of the upper case 13 as a component is not increased, so that the cost is not increased. In addition, since the upper frame 40 and the lower frame 41 are assembled and fixed to the upper case 13 at the same time, the process of assembling the motor 16 is simplified, and the cost is reduced. The code reel unit 17 is not limited to the one having the automatic winding mechanism, and may have a manual winding mechanism using winding means such as a handle. By exposing the winding means to the outside of the upper case 13 via the transmission means and the transmission means, the pair of power supply terminals 47 can be located on the opposite side of the motor 16 and the case where the automatic winding mechanism is provided. Similar effects can be obtained. As described above, the mixer according to the present invention includes the cutting means which is rotationally driven by the electric motor in the main body in the container placed on the upper part of the main body, and controls the operation of the electric motor. A mixer for cooking the object to be cooked in the container by rotating the cutting means by operating a switch to perform the operation, wherein a central part in a width direction of a switch unit provided with the switch ;
The central portion of the horizontal width direction, and a center portion of the lateral width direction of the installed code reel wound the power cord to the interior to a vertically placed condition in layers coincides with the longitudinal direction of the body
And the main body is arranged so as to coincide with the center in the lateral width direction . For this reason, the power cord is formed into a code reel unit and is arranged at a position where the front-rear direction of the main body is enlarged . Also, a central portion of the switch unit in the width direction,
Align the center of the motor in the width direction with the center of the code reel unit in the width direction.
Aligned to the front and back of the body and aligned with the center of the body in the width direction
The motor is heavy and the cord reel unit is relatively heavy.
It has become. Further, the container containing the food was placed above the electric motor.
Because the main unit is heavy, the position of the center of gravity of the mixer and the switch unit
The central part in the lateral width direction can be matched in the front-rear direction. Because of this,
The direction in which the switch is pressed is the direction of the center of gravity of the mixer.
This prevents the xers from rotating around the center of gravity and changing direction,
It is possible to stabilize the mixer when the switch is operated.
