Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a hand mixer, and relates to a storage device for a beater as an attachment.

(b) Conventional technology In conventional hand mixers, for example,
Like the ``beater case for a hand mixer'' in Publication No. 18766, one side is open, and the opening is removably closed to the main body of the hand mixer, and a partition wall with a groove for receiving the shaft of the beater divides the space. It is common practice to use a beater case for a hand mixer that is separated into two chambers. However, the beater case only increases the size of the hand mixer, and is especially useful for cordless hand mixers that use rechargeable batteries. In the case of a mixer, there was a problem that there was no need to store the cord, so it was wasted.

(c) Problem to be solved by the invention The problem to be solved by the invention is to provide a place to store the beater of the hand mixer in a place other than the beater case, which is a separate part.

(d) Means for solving the problem A reduction mechanism unit consisting of a rechargeable battery inside the main body case, a motor driven by the battery, and a plurality of gears connected to the drive shaft of the motor. A drive shaft is installed at the bottom of the main body case, and a beater for a hand mixer can be detachably attached to the drive shaft. A locking member for removably holding the beater is formed on one external side of the main body case.

(e) Function: Store the beater in the side of the main body case while the hand mixer is not in use.

(F) Embodiment The rechargeable hand mixer of the present invention will be described in detail below with reference to an embodiment of the drawings.

1 is a hollow main body case of a hand mixer made of synthetic resin (e.g. ABS, AS, etc.);
This case 1 is made by superposing two front and rear divided cases 13 and 14, and is composed of a box-shaped working part 1a and an elongated hand-held part 1b. This working part 1
A has a pair of round holes 2a and 2b formed in its bottom surface 1c, and a rectangular opening 3 and a small hole 4 formed in its top surface. 5 is swingably attached, and is configured to allow light from a light emitting diode 6, which indicates that charging is in progress, to pass through the small hole 4.

Reference numerals 7, 8, and 9 indicate rechargeable nickel-cadmium batteries stored in the battery storage section 10 in the handheld portion 1b of the case 1, and the batteries 7, 8, and 9 are connected in series with each other, and are A DC charging current is supplied from a charging mechanism section that includes a step-down transformer 11 and other charging circuit components (not shown) housed in section 1a.

Reference numeral 12 denotes a charging plug which can be rotated in the rear split case 14 to take a storage state where it is located on the same surface as the case 14 and a usage state where it is in a protruding position, and which supplies commercial AC power to the step-down transformer 11. It acts as a relay for the supply.

Reference numeral 15 denotes a DC motor that can be driven by being supplied with drive current from the batteries 7, 8, and 9, and its drive shaft 17 is connected to a motor support wall 16 formed in the working section 1a of the case 1. bottom 1c of
It is placed facing the direction.

Reference numeral 18 denotes a reduction mechanism unit connected to the motor 15 to reduce its rotational speed and increase its rotational moment, which includes a gear A19 fitted to the drive shaft 17, and a large diameter gear A19 that meshes with the gear A19. A gear B22C23 having gears 20 and 21, respectively, and pivotally supported by the case 1; a large gear B22C23 that is integrally formed with the gears B22 and C23 and meshes with small diameter gears 24 and 25 that rotate coaxially with the large diameter gears 20 and 21; The drive shafts A30 and B31 have hollow cylindrical shape and are rotatably supported and fixed by ribs 28 and 29 provided in the case 1, respectively.

Reference numeral 32 denotes a switch section housed in the working section 1a, which opens and closes between a switch component case 34 attached to a printed circuit board 33 disposed on the upper surface of the motor support wall 16 and contacts (not shown) inside the component case 34. It consists of the operation button 5 to Further, the light emitting diode 6 has its lead electrically connected to the printed circuit board 33.

35 and 36 are beaters A and B for a hand mixer, the shaft portions 35a and 36a of which are connected to the drive shaft A3.
0, B31 are press-fitted into the fitting parts 30a, 31a formed in the shaft parts 35a, 36a, and collar parts 37, 38 are formed in the middle of the shaft parts 35a, 36a. Fitting portions 30a, 3
1a, and the fitting portions 30a, 31a are provided with the shaft portions 35a, 36a.
chuck portions 39a, 39b sandwiching the chuck portions 39a, 39b are provided, and a rubber ring 40 is provided for biasing the chuck portions 39a, 39b into a closed state. Therefore, when the shaft portions 35a, 36a are advanced into the insertion portions 30a, 31a, the chuck portions 39a, 39b are once opened by the bulged portions 41a, 41b, and when the shaft portions are advanced further inward, the chuck portions 39a, 39b are opened. When closed again, the shaft portions 35a and 36a cannot be easily removed.

42 is a T-shaped spring member for articulately moving the charging plug 12 between the stored state and the protruding state; 43a and 43b are the charging plug 12;
The charging plug 12 is a contact piece that contacts at a protruding position to supply alternating current to the step-down transformer 11, and the structure of the charging plug 12 and its vicinity is a conventionally well-known technology.

44 and 45 are a pair of elastic arm pieces 44a and 44, respectively.
This is a locking member for the beaters A35 and B36 when not in use, consisting of 45a and 45b. The locking members 44, 45 are integrally formed on one side of the outside of the main body case 1, and when the hand mixer is not in use, the beaters A35, B36 can be pulled out from the insertion portions 30a, 31a of the drive shafts A30, B31, and the locking members 44, 45 can be pulled out from the fitting parts 30a, 31a of the drive shafts A30, B31. Stop member 4
4,45 to store it. The beater A3
5, The latching pin 4 is attached to the shaft portions 35a and 36a of B36.
6 are provided protrudingly, and the beaters A35, B36
It acts as a stopper when hooking on the locking members 44, 45.

(g) Effects of the invention As explained above, the invention consists of a rechargeable battery inside the main body case, a motor driven by the battery, and a plurality of gears connected to the drive shaft of the motor. A rotation shaft that houses a reduction mechanism and is rotated by a gear constituting the reduction mechanism is installed at the bottom of the main body case, and a beater for a hand mixer is detachably attached to this rotation shaft. In addition, since a locking member for removably holding the beater is formed on one external side of the main body case, the beater can be made compact when not in use without using a large beater case as in the conventional case. It has the advantage of being able to be stored in the main body case, and is particularly effective for rechargeable hand mixers.
