Motor side magnet 252 in the beverage making device 1 of the present invention can solve the problems, such as above-mentioned installation method.With Under, the motor side magnet 252 in the beverage making device 1 of embodiments of the present invention and its installation method are carried out specifically It is bright.

Figure 12 B are the exploded perspective views for being illustrated to the motor side magnet 252 in embodiments of the present invention.Electricity Pusher side magnet 252 has the hole 252h1 for being used for passing through rotary shaft 251 along the central shaft of cylindrical shape.In addition, such as Figure 12 B Shown, a part of the motor side magnet 252 in its side is provided with hole 252h2.Hole 252h1 is one of the first hole, and hole 252h2 is One of second hole.Hole 252h2 is for example set to, from motor side magnet on the direction of the central axis with motor magnet 252 The circumferential lateral surface of 252 side penetrates into the circumferential lateral surface of opposite side.

Moreover, it is provided with the rotary shaft 251 of electric motor for pump 25 with the hole 252h2 of motor side magnet 252 diameter almost Identical hole 251h.Hole 251h is one of the 3rd hole.Hole 251h is, for example, in the pivot with columned rotary shaft 251 The hole for penetrating rotary shaft 251 on vertical direction.

Bullet is set in a manner of in the hole 252h2 of motor side magnet 252 and the hole 251h of rotary shaft 251 by simultaneously Spring pin 253.Motor side magnet 252 is arranged in rotary shaft 251 by the spring catch 253.Spring catch 253 is the one of pin member Example, the diameter of spring catch 253 are formed as the diameter of the hole 251h with the hole 252h2 of motor side magnet 252 and rotary shaft 251 almost It is identical.

The length of spring catch 253 is for example set as, fully long compared with the diameter of rotary shaft 251, and is motor side magnet Below 252 diameter.If from the viewpoint of motor side magnet 252 is more securely fixed in rotary shaft 251, preferably make bullet The length of spring pin 253 is the length almost identical or slightly shorter with the diameter of motor side magnet 252.

In addition, motor side magnet 252 be after ferrite magnet or neodymium magnet etc. more carefully are crushed kneading into resin etc. Obtained from bonded permanent magnet.The reasons why using bonded permanent magnet to motor side magnet 252 is made according to Magnaglo is baked The sintered magnet made, then in punching etc., magnet can be crushed so being difficult to, it is necessary to be molded in the stage baked, therefore Need to make mould etc. again, cost improves.By using bonded permanent magnet to motor side magnet 252, so as to by easily Shaping and processing, hole 252h1 and hole 252h2 for passing through rotary shaft 251 is made.

<1-9. action effect>

As described above, in the beverage making device 1 of embodiments of the present invention, motor side magnet 252 is formed as cylinder Shape, have：For making the hole 252h1 (the first hole) that rotary shaft passes through and the circumferential lateral surface in cylinder along the central shaft of cylinder The hole 252h2 (the second hole) of opening, rotary shaft 251 have hole 251h (the 3rd hole), and motor side magnet 252 passes through simultaneously in hole Spring catch 253 (pin member) installation passed through in 252h2 and hole 251h is on the rotary shaft.

Using such structure, beverage making device 1 according to the embodiment of the present invention, can pacify without using projection etc. Part is filled, and motor side magnet 252 is appropriately mounted in the rotary shaft 251 of electric motor for pump 25.Specifically, can bear To the attraction of direction of insertion (axial direction), in a manner of motor side magnet 252 can not moved by the axial direction relative to rotary shaft 251 Firmly fix, and can with motor side magnet 252 in the rotation of electric motor for pump 25 relative to the rotation side of rotary shaft 251 To skid-resistant mode, motor side magnet 252 is arranged in rotary shaft 251.

In addition, according to said structure, the size (fore-and-aft direction of beverage making device 1 of motor side magnet 252 can be reduced On thickness), the overall space saving of beverage making device 1 can be realized.Further, since installing component is not needed, so energy Enough reduce the manufacturing cost of beverage making device 1.

In addition, in the beverage making device 1 of embodiments of the present invention, motor side magnet 252 is formed by bonded permanent magnet. Utilize such structure, beverage making device 1 according to the embodiment of the present invention, it is not necessary in order to be formed on sintered magnet Hole 252h1 and hole 252h2 etc. and prepare mould etc. to be molded, manufacturing cost can be reduced.In addition, resin in bonded permanent magnet Deng for main component, it is possible to easily go out hole 252h1 and hole 252h2 using existing technology.

<1-10. variation>

In the above-described embodiment, the hole 251h of rotary shaft 251 is set to penetrate rotary shaft 251, but the present invention is not It is limited to this.That is, hole 251h can also perforate to the midway of rotary shaft 251.In this case, hole 251h depth is formed as, Spring catch 253 is inserted into the depth that spring catch 253 when in the 251h of hole is sufficiently immobilized in rotary shaft 251.

In addition, the position that hole 252h2 is gone out in motor side magnet 252 is for example determined in the following fashion.Figure 13A to Figure 13 D is the figure illustrated for the determining method of the position of the hole 252h2 to motor side magnet 252.

The motor side magnet 252 of example is in the face of the side coupled with pump side magnet 745 (Figure 13 A in Figure 13 A and Figure 13 B And the face on the right side in Figure 13 B) on there are a N poles and this two poles of the earth of a S poles.Here, in Figure 13 A and Figure 13 B example electricity Pusher side magnet 252 is configured to only stretch out the magnetic line of force from coupling surface to couple securely with pump side magnet 745.Specifically, exist As in fig. 13 a in the case where the above-below direction of coupling surface configures pole different from each other, the magnetic line of force as shown in Figure 13 B, Describe U-shaped in section.Figure 13 B dotted line is the line that example is carried out to the magnetic line of force.In this case, not from motor side magnetic The magnetic line of force is stretched out in the face (face in the left side in Figure 13 A and Figure 13 B) for the opposite side in face that body 252 couples, so being sent out not as magnet The effect of waving.

In the case where motor side magnet 252 has such magnetic line of force, in order to not reduce the magnetic of motor side magnet 252 Power, as shown in Figure 13 B, preferably as much as possible by hole 252h2 located at the position that the magnetic line of force does not pass through.In other words, preferably hole 252h2 For example located at the position of the boundary face along magnetic pole in Figure 13 B.

In addition, in Figure 13 B mesopores 252h2 located at the position that the magnetic line of force does not pass through, but hole 252h2 can only be located at cut-out In the case of the position of the magnetic line of force, hole 252h2 is preferably located at the motor side magnet away from the nearer side of coupling surface as much as possible 252 side.This is because, as shown in Figure 13 B, away from the nearer magnetic line of force (magnetic line of force A) of coupling surface than the face away from opposite side compared with The near magnetic line of force (magnetic line of force B) is short, and the magnetic force reduction in the case that the magnetic line of force is cut off by hole 252h2 is less.

On the other hand, in Figure 13 C and Figure 13 D the motor side magnet 252 of example in the side coupled with pump side magnet 745 There are two N poles and this four poles of two S poles on face (face on the right side in Figure 13 C and Figure 13 D).As shown in fig. 13 c, coupling Face up and down side set up pole different from each other in the case of, the magnetic line of force as illustrated in figure 13d, in section describe with coupling It is generally fan-shaped centered on the corner in conjunction face.Figure 13 D dotted line is the line that example is carried out to the magnetic line of force.In this case, with figure 13A and Figure 13 B similarly, do not stretch out the magnetic line of force, so not as magnetic from the face of the opposite side in the face that is coupled with motor side magnet 252 Body plays a role.

In the case where motor side magnet 252 has such magnetic line of force, also with the two poles of the earth shown in Figure 13 A and Figure 13 B Situation is likewise it is possible to which hole 252h2 to be located to the side of the motor side magnet 252 away from the nearer side of coupling surface as much as possible. In order to further suppress the reduction of magnetic force, as illustrated in figure 13d, hole 252h2 is located at the opposite side of coupling surface that the magnetic line of force does not pass through Face is nearby.

That is, in the present invention, it is preferred to which the hole 252h2 of motor side magnet 252, which is located at, passes through columned motor side magnet 252 Central shaft, and the position that the magnetic line of force does not pass through.

In addition, in Figure 13 B and Figure 13 D, the magnetic line of force with dotted line example is conceptual, it is impossible to describes motor exactly The magnetic line of force that side magnet 252 should have.In addition, in the present invention, the location and shape for the magnetic line of force that motor side magnet 252 has It is not limited to the example shown in Figure 13 B and Figure 13 D.Moreover, hole 252h2 position is also not necessarily limited to the position of example in Figure 13 A to Figure 13 D Put.The position not passed through for hole 252h2, the magnetic line of force that being preferably disposed to motor side magnet 252 has, it is being difficult to be located at the magnetic line of force In the case of the position not passed through, the magnetic line of force for being arranged to cut off hole 252h2 as much as possible is shorter.

In addition, in Figure 13 C and Figure 13 D, hole 252h2 is extremely corresponding with the S on coupling surface located at motor side magnet 252 Lateral parts, but the invention is not restricted to this.For example, hole 252h2 can also be located at motor side magnet 252 with coupling surface The extremely corresponding lateral parts of N.
