BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are given the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.
<Overall composition>

First, the overall configuration of the mixer 100 according to this embodiment will be described. The mixer 100 is mainly composed of a main body 160 and a cup unit 110, as shown in FIGS. A cup unit (container) 110 stores an object to be cooked. The main body 160 provides power for the cutter for stirring and cutting the food items in the cup unit 110 .

As for the mixer 100 according to the present embodiment, the cup unit 110 is detachably attached to the main body 160 as shown in FIGS.
<Configuration of main body 160>

Next, the configuration of the main body 160 according to this embodiment will be described. As shown in FIGS. 3 and 5, in the present embodiment, the main body 160 mainly includes a main body cover 161, an operation section 162, a power cord 163, a motor 164, a rotating shaft 165, and a driving force. transmission gear 166; The main body cover 161 is formed in a substantially pyramidal shape, and the operation part 162 is attached to the outside thereof, and the motor 164, the rotating shaft 165, etc. are mounted inside thereof. Then, the mixer 100 drives the motor 164 when receiving an operation ON command from the user via the operation unit 162 . The driving force of the motor 164 is transmitted to the cutter 141 located inside the upper cup unit 110 via the rotary shaft 165 and the driving force transmission gear 166 .

Particularly in the present embodiment, as shown in FIGS. 5 and 6, body cover 161 has upper outer peripheral surface 161A recessed inward. More specifically, the main body cover 161 has a step 161B formed along the entire circumference at a position approximately one-third from the upper end.

Packings 171A and 171B are attached to the upper and lower ends of the outer peripheral surface 161A. More specifically, a packing 171A is attached to the upper end of the outer peripheral surface 161A over the entire circumference of the upper end surface of the main body cover 161. As shown in FIG. A packing 171B is attached to the stepped portion 161B along the entire circumference of the lower end portion of the outer peripheral surface 161A.

A design member 172 is attached to the surface of the outer peripheral surface 161A. The design member 172 is, for example, a highly designed sheet-like member such as metal or resin. However, instead of the design member 172, a design may be painted on the outer peripheral surface 161A.

The outer peripheral surface of the design member 172 is covered with a transparent cover 173 . More specifically, the upper end of the transparent cover 173 is bent toward the center of the main body 160 , that is, to cover the upper end surface of the main body 160 . A lower end surface of the entire outer periphery of the cup body 120 is positioned directly above the entire periphery of the bent portion 173X of the cover 173 . They are separated by such a distance that they are likely to abut each other during the stirring operation of the mixer 100 .

Between the lower surface of the bent portion 173X of the cover 173 and the upper end surface of the body cover 161, the packing 171A is sandwiched over the entire circumference as described above. Between the lower end surface of the transparent cover 173 and the stepped portion 161B of the body cover 161, the packing 171B is sandwiched over the entire circumference, as described above.

As a result, even when the cutter 141 performs a stirring operation or a cutting operation, the packings 171A and 171B can absorb the vibration transmitted from the cup unit 110 and the main body 160, thereby suppressing the degree of their resonance. be possible.

Moreover, with this configuration, it is possible to reduce the possibility of moisture adhering to the design member 172 while enhancing the design of the main body 160 and the mixer 100 as a whole. For example, even if the design member 172 is made by punching a sheet of metal, water is less likely to adhere to the metal, and as a result, the metal is less likely to corrode. Alternatively, even if the design member 172 is a sheet of paper with a design, water is less likely to adhere to the paper. In other words, it becomes possible to increase the degree of freedom in designing the main body 160 .
<Configuration of cup unit 110>

Next, the configuration of the cup unit 110 according to this embodiment will be described. 4 and 5, in the present embodiment, cup unit 110 includes cup body 120, lid 130, and attachment portion 140. As shown in FIG.

In this case, it is preferable that the convex portion formed on the rear portion of the lid 130 is also engaged with the concave portion on the rear side.

Two engaging portions 120Y, 120Y for engaging left and right claws 130Y, 130Y formed on the bottom surface of the rear portion of the lid 130 are formed at the connecting portion between the body portion 120A and the handle 120B.
(Lid 130)

The lid 130 according to the present embodiment, as shown in FIGS. 5, 9 and 10, mainly corresponds to a cylindrical portion 130A inserted from above into the trunk portion 120A of the cup body 120 and a base portion of the cylindrical portion 130A. A flat portion 130B is also configured. The plane portion 130B is formed of a plane portion 130B for covering the top of the columnar portion 130A, the top of the outer periphery of the barrel portion 120A, the top of the spout 120C, and the top of the handle 120B in plan view.

A packing 131 is attached to the outer circumference of the lower portion of the cylindrical portion 130A. As a result, when the upper portion of the cup body 120 is closed by the lid 130, the possibility of leakage of liquid or the like from the gap between the lid 130 and the cup body 120 can be reduced.

Here, a configuration for attaching and fixing the lid 130 to the cup body 120 will be described. First, convex portions 130X and 130X are formed on the right and left sides of the front portion of the outer peripheral surface of the cylindrical portion 130A. Protrusions 130X and 130X are configured to be able to be locked to recesses 120X and 120X of trunk portion 120A when the upper portion of cup body 120 is closed by lid 130 .

In the present embodiment, convex portions are also formed on the right and left sides of the rear portion of the outer peripheral surface of the cylindrical portion 130A. Each of the projections is configured to be engageable with a recess formed in the rear portion of the inner peripheral surface of the trunk portion 120A when the upper portion of the cup body 120 is closed with the lid 130 .

Claws 130Y and 130Y are formed on the right and left sides of the bottom surface of the rear portion of the planar portion 130B. As shown in FIG. 11, the claws 130Y and 130Y are two engaging portions 120Y and 120Y formed at the connecting portion between the body portion 120A and the handle 120B when the upper portion of the cup body 120 is closed by the lid 130. configured to be lockable.

That is, in the present embodiment, the lid 130 is fixed to the cup body 120 by the frictional force of the packing 131, the front projections 130X, 130X, the rear projections, and the claws 130Y, 130Y. .

Thereby, the user can remove the lid 130 from the cup body 120 by pushing up the rear end portion of the flat portion 130B of the lid 130 while gripping the handle 120B. More specifically, for example, the user holds the handle 120B with the index finger, the middle finger, the ring finger, the little finger, and the palm, and lifts the rear end portion of the flat portion 130B with the pad of the thumb. As a result, the claw portions 130Y and 130Y of the lid 130 are disengaged from the locking portions 120Y and 120Y of the cup main body 120, and the convex portions 130X and 130X contact the upper end portions of the concave portions 120X and 120X, respectively. The rear portion of the lid 130 rotates upward about the axis.

Further, in the present embodiment, ribs 130Z and 130Z are formed on the left and right sides of the front side of flat portion 130B around cylindrical portion 130A on the bottom surface of flat portion 130B. As a result, when the rear end portion of the lid 130 is lifted, the ribs 130Z, 130Z come into contact with the upper end surface of the trunk portion 120A of the cup body 120, and the contact portion is used as a fulcrum, using the principle of leverage. , the rear end of the lid 130 can be easily lifted by the user.

Incidentally, the ribs 130Z, 130Z are preferably formed behind the projections 130X, 130X. As a result, when the rear end portion of the lid 130 is lifted, the contact portion between the ribs 130Z and 130Z and the upper end surface of the body portion 120A serves as a fulcrum at first, and the rear portion of the lid 130 is lifted. The rear portion of the lid 130 is lifted using the contact portions between the convex portions 130X, 130X and the concave portions 120X, 120X as fulcrums.

Further, in the present embodiment, as shown in FIGS. 7 to 9 and the like, a stepped portion 120H is formed near the upper end of the rear portion of the inner peripheral surface of the trunk portion 120A. More specifically, the stepped portion 120</b>H is formed several millimeters above the packing 131 when the upper portion of the cup body 120 is closed by the lid 130 . The stepped portion 120H includes a notch portion 120J that is notched downward from the upper edge of the cup body 120, a thin portion 120K that is inserted into the handle 120B side (diametrically outward) of the inner surface of the cup body 120, including.

As a result, when the rear portion of the flat portion 130B of the lid 130 is lifted upward by several millimeters when the lid 130 is released, the packing 131 first moves above the step 120H. As a result, external air flows from the step 120H through the lower side of the packing 131 and into the internal space of the barrel portion 120A, reducing the negative pressure in the internal space of the barrel portion 120A. can be removed from the cup body 120. That is, the stepped portion 120H serves as a ventilation portion that facilitates the flow of air between the inside and outside of the cup body 120 (the thin portion 120K and the notch portion 120J) when the lid 130 is opened.

Here, returning to FIG. 5, in the present embodiment, when the upper portion of cup body 120 is closed by lid 130, the bottom surface of body portion 120A of cup body 120 to the bottom surface of flat portion 130B of lid 130 is 169.5 mm. In addition, when the upper portion of cup body 120 is closed by lid 130, length L2 from the bottom surface of body portion 120A of cup body 120 to the lower end of cylindrical portion 130A of lid 130 is 141.1 mm. Also, in a state where the upper part of the cup body 120 is closed by the lid 130, the length from the bottom surface of the body part 120A of the cup body 120 to the top X (1 liter in this embodiment) of the scale of the cup body 120 L3 is 125.2 mm. That is, when the upper portion of cup body 120 is closed by lid 130, length L4 from the top of the scale to the lower surface of flat portion 130B is 44.3 mm.

Then, referring to FIGS. 5 and 10, the substantially central portion of flat portion 130B, more specifically, the central portion of body portion 120A of cup body 120 when the upper portion of cup body 120 is closed with lid 130 is An air hole 130D is formed in a portion located directly above. This can reduce the degree to which the pressure in the interior space of the barrel 120A rises when the top of the cup body 120 is closed by the lid 130, resulting in the possibility of the lid 130 coming off during operation. can be reduced. Incidentally, in the present embodiment, the diameter L5 of air hole 130D is formed to be 2.7 mm.

Especially in the present embodiment, a first rib 130E is formed around the air hole 130D on the bottom surface of the plane portion 130B. The first rib 130E is formed in a substantially cylindrical shape. In this embodiment, the height L6 of the first rib 130E is 13.4 mm. As a result, even if the liquid in the body portion 120A is agitated, it is possible to reduce the possibility of the liquid splashing outside through the air holes 130D.

More specifically, the first rib 130E is inclined such that the inner diameter increases with increasing distance from the base of the flat portion 130B.

Further, in the present embodiment, the diameter L7 of the inner circumference of the base portion of the first rib 130E with respect to the plane portion 130B is formed to be larger than the diameter L5 of the air hole 130D. In this embodiment, the diameter L7 of the inner circumference of the base of the first rib 130E with respect to the plane portion 130B is 4.8 mm.

A second rib 130F is formed around the first rib 130E on the lower surface of the planar portion 130B. The height L6 of the first rib 130E is formed higher than the height L8 of the second rib 130F. In addition, in the present embodiment, the height of the second rib 130F is formed to be 3.4 mm. The inner peripheral diameter of the base of the second rib 130F relative to the plane portion 130B is 2.8 mm larger than the outer peripheral diameter of the base of the first rib 130E relative to the plane portion 130B.

The second rib 130F has a mountain-like cross section. That is, the second rib 130F has an outer peripheral surface that is inclined, and an inner peripheral surface that is also inclined.

As a result, as shown in FIG. 12, even if the cutter 141 agitates the liquid in the body portion 120A, the force pushing the lid 130 upward by the liquid can be dispersed in the left-right direction, and the liquid can disperse the lid 130. As shown in FIG. is likely to come off from the cup body 120. It is also possible to reduce the possibility that the liquid adhering to the lower surface of the lid 130 will travel along the first ribs 130E and reach the air holes 130D.

5 and 10, in order to make the mixer 100 compact, for example, when the upper part of the cup body 120 is closed by the lid 130, the top of the scale of the cup body 120 is shifted from the top X to the flat part. It is preferable that the length L4 to the lower surface of 130B is about 40 mm to 50 mm. In this case, the diameter L5 of the air hole 130D is preferably about 2 mm to 4 mm, more preferably about 2.2 mm to 3.2 mm. In addition, it is preferable that the diameter L7 of the inner circumference of the base of the first rib 130E is larger by about 1 mm to 3 mm than the diameter L5 of the air hole 130D. Also, the height L6 of the first rib 130E is preferably set to about 10 mm to 20 mm, and the height L8 of the second rib 130F is preferably set to about 2 mm to 5 mm.
