The specific embodiment

Below, illustrate referring to the drawings illustrative embodiment of the present invention.

Fig. 1 is the conceptual sectional view of garbage disposer 1 that shows an example of embodiments of the present invention.Garbage disposer 1 is arranged on the below of kitchen sink 2 and will carries out from the garbage (not shown) that kitchen sink is cast broken device, have upper sleeve 3, be arranged on upper sleeve 3 the below lower parts casing pipe 4 and be arranged on the motor housing 5 of the below of lower parts casing pipe 4.

Be fixed with fixed blade 6 in lower parts casing pipe 4, dispose swivel plate 7 in the inboard of fixed blade 6.Swivel plate 7 is driven by the motor that is built in motor housing 5 (not shown), rotates around axis of rotation 8.In addition, installation pendulum 9 on swivel plate 7, pendulum 9 rotates around turning cylinder 10.Need to prove, the space of the top of the swivel plate 7 of the inside of lower parts casing pipe 4 is called crushing chamber 11, the space of the below of swivel plate 7 is called discharges chamber 12.

The garbage of being cast by kitchen sink 2 enters crushing chamber 11 through upper sleeve 3.Enter the garbage of crushing chamber 11 under the effect of the centrifugal force that is produced by the rotation of swivel plate 7, fly to the radial direction of swivel plate 7, strike pendulum 9 and press to be paid in fixed blade 6.Press to be paid in the garbage of fixed blade 6 and be broken and fall into and discharge chamber 12, discharged by discharge pipe 13.

Here, with reference to Fig. 2 to Fig. 6, the form of the fixed blade 6 that consists of this garbage disposer 1 is elaborated.Here, Fig. 2 is the plan view (figure that observes from the A direction of Fig. 1) of fixed blade 6, and Fig. 3 is the stereogram of fixed blade 6.In addition, Fig. 4 observes the expanded view of fixed blade 6 from inboard (the B direction of Fig. 2).In addition, Fig. 5 is the horizontal sectional view that fixed blade 6 is dissectd along the CC ' line of Fig. 4.In addition, Fig. 6 is the vertical cross-section diagram of fixed blade 6.

By Fig. 2 and Fig. 3 as can be known, fixed blade 6 forms ring-type on the whole.In addition, alternately configure a plurality of ditch section 21 and tooth section 22 on the medial surface of ring.Here, ditch section 21 refers to the recess that the inner surface in fixed blade 6 forms.Tooth section 22 refers to the protuberance in the inner surface formation of fixed blade 6.Need to prove, as shown in Figure 2, swivel plate 7 is with (direction shown in arrow R) rotation counterclockwise when observing above garbage disposer 1.

In addition, by Fig. 3 and Fig. 4 as can be known, fixed blade 6 has highly different 3 kinds of tooth sections 22.That is the low tooth 22l of section of 1/2 left and right height of the height that, be formed with the high tooth 22h of section that height equates with the height of fixed blade 6 in fixed blade 6, has fixed blade 6 and have the high tooth 22h of section and the low tooth 22l of section between the middle tooth 22m of section of height.

The high tooth 22h of section configures on circumference with 45 ° of tooth pitches in plan view (Fig. 2).That is, 8 high tooth 22h of section are arranged on fixed blade 6, in a circumferential direction uniformly-spaced configuration.In other words, the ring of fixed blade 6 is separated into 8 zones by the high tooth 22h of section.In aforementioned 8 zones, have the Y zone that the low tooth 22l of section and the middle tooth 22m of section mix the X zone of configuration and only configured the low tooth 22l of section, and X zone and the regional alternate configurations (with reference to Fig. 4) of Y.In more detail, 1 the middle tooth 22m of section of central configuration in the X zone in its both sides, namely configures 4 low tooth 22l of section between the middle tooth 22m of section and the high tooth 22h of section.In addition, 9 low tooth 22l of section of configuration in the Y zone.

Like this, has the tooth section 22 of highly different 3 kinds due to fixed blade 6, be the high tooth 22h of section, the middle tooth 22m of section and the low tooth 22l of section, to be depressed into the roughly severing of garbage of fixed blade 6 by the high tooth 22h of section, afterwards, by the further severing of the middle tooth 22m of section, be broken at last carefullyyer by the low tooth 22l of section, fall into and discharge chamber 12.Therefore, can efficiency broken garbage well.

In addition, as shown in Figure 4,3 kinds of tooth 22 (the high tooth 22h of section, middle tooth 22m of section of section, the low tooth 22l of section) have what is called " tilt mechanism (スキユ one) ", the shape of facing of tooth section 22 is tilted to the right 20 ° with respect to vertical axis (axle parallel with axis of rotation 8).As previously mentioned, swivel plate 7 is rotated counterclockwise, therefore in Fig. 4 garbage from the right side near tooth section 22, be skewed mechanism from the right side near the garbage of tooth section 22 and press to the below, be pressed into and discharge in chamber 12 and fall.Its result is discharged the garbage efficiency well.

Then, the horizontal cross sectional geometry for tooth section 22 (the high tooth 22h of section, the middle tooth 22m of section, the low tooth 22l of section) describes.

As shown in Figure 5, the width W 2 of tooth section 22 is less than the width W 1 at the top of ditch section 21.Therefore, compare with prior art products in fixed blade 6, form a plurality of ditch section 21 and tooth section 22.In present embodiment, the internal diameter of fixed blade 6 is 151.4mm, and the width W 1 of ditch section 21 is 4mm, and the width W 2 of tooth section 22 is 1.9mm, therefore, has formed 80 ditch sections 21 and tooth section 22 on fixed blade 6.Each is 4mm to suppose width W 1 and width W 2, namely constitutes with prior art products equally, and ditch section 21 and tooth section 22 can only form approximately 60.In addition, the sectional area of the ditch section 21 of present embodiment is about 8.9mm ², roughly the same with prior art products.Therefore, if swivel plate 7 carries out 1 rotation, can the broken garbage of approximately 1.3 times (≈ 80/60) volumes of product in the past.That is, if the rotary speed of swivel plate 7 is identical, can come broken garbage with the approximately speed of 1.3 times of prior art products so.

The cross section shape of tooth section 22 is that front end attenuates, and namely the width W 3 of the base portion of tooth section 22 is larger than the width W 2 at top.Therefore, can not damage the mechanical strength of tooth section 22, and the number of ditch section 21 is maximized.

Diminish by the width W 2 with tooth section 22, when swivel plate 7 rotation, can reduce the frictional resistance from fixed blade 6 that swivel plate 7 is subject to.Therefore, can realize with lower motor output.That is, can make motor miniaturization or reduction power consumption.

Can also further reduce the width W 2 at the top of tooth section 22.For example, as shown in Figure 6, can also be with the width W 2 at the top of tooth section 22 close to 0, namely the cross sectional shape of tooth section 22 is triangle.Formation if so can make the frictional resistance from fixed blade 6 that swivel plate 7 is subject to minimize.Thereby can reduce the power consumption of motor.

Owing to being rotated counterclockwise from overlooking swivel plate 7, in Fig. 5, garbage, swivel plate 7 move to the left from the right side of fixed blade 6.In addition, the horizontal section shape of ditch section 21 tilts in the direction towards swivel plate 7.That is, the center line M of the horizontal section of ditch section 21 tilts to the right.Resistance force diminishes when therefore, garbage is in importing ditch section 21.Therefore, can garbage efficient is broken well.In addition, can reduce the power that drives swivel plate 7.That is, can reduce the power consumption of motor.

Then, the vertical cross-section shape for the middle tooth 22m of section and the low tooth 22l of section describes.

As shown in Figure 7, on the cross section that fixed blade 6 is dissectd along the plane of the axis of rotation that comprises fixed blade 6 (that is, vertical cross-section), has inclined plane 22s in the upper end of the middle tooth 22m of section and the low tooth 22l of section.This inclined plane 22s tilts, towards inboard (axis of rotation 8) step-down of fixed blade 6.Therefore, even garbage is arranged in the upper end of the tooth 22m of section and the low tooth 22l of section, garbage also can fall into the inboard of fixed blade 6 along inclined plane 22s downslide, can not remain in the upper end of the middle tooth 22m of section and the low tooth 22l of section.Therefore, can efficiency broken garbage well.

So far, to having 3 kinds of tooth sections 22, i.e. the high tooth 22h of section, the fixed blade 6 of the middle tooth 22m of section and the low tooth 22l of section is illustrated, but fixed blade 6 is not limited to this.Can also constitute the appearance of Fig. 8 or Fig. 9.Need to prove, Fig. 8 and Fig. 9 are the expanded views that shows the variation of fixed blade 6, are the figure when observing fixed blade 6 from the inboard.

Fixed blade 6 shown in Fig. 8 does not have aspect tilt mechanism, different from shown in Fig. 4, although have the high tooth 22h of section and the low tooth 22l of section does not possess the middle tooth 22m of section, and different from shown in Fig. 4.The high tooth 22h of section is separated into some zones by the high tooth 22h of section with fixed blade 6 in the first-class arranged spaced of fixed blade 6, a plurality of low tooth 22l of section of configuration in this zone.Like this, the fixed blade 6 shown in Fig. 8 and comparing shown in Fig. 4, simple structure, thereby easily make.

Fixed blade 6 shown in Fig. 9, do not have tilt mechanism aspect and not have the aspect of the middle tooth 22m of section identical with the fixed blade 6 shown in Fig. 8, but every two adjacency of the high tooth 22h of section, soon 2 high tooth 22h of section be configured to a pair of, not identical on this point.Need to prove, " a pair of " here refers to not have between 2 adjacent high tooth 22h of section the meaning of the low tooth 22l of section of configuration.A pair of owing in this wise 2 high tooth 22h of section being configured to, when pulverizing garbage, can reduce the load of each high tooth 22h of section.Therefore, suppress the abrasion of the high tooth 22h of section.

The quantity of the low tooth 22l of section of configuration in (i.e. " zone ") between the adjacent high tooth 22h of section, can select arbitrarily corresponding to kind of the garbage of the processing object of garbage disposer 1 etc., but the experimental result according to the inventor, can obtain best result when as shown in figure 10, in each zone, 2 low tooth 22l of section being set respectively.In addition, fixed blade 6 as shown in figure 10 comprises 7 continuous zones of low tooth section, by having such zone, can suppress the obstruction of garbage.

Quantity for the high tooth 22h of section of configuration on fixed blade 6 also can be selected arbitrarily, but do not contact simultaneously the such configuration of the high tooth 22h of section with all a plurality of (normally 2) pendulums 9 of configuration on swivel plate 7 and select number, can avoid swivel plate 7 (driving the motor of swivel plate 7) is applied large load.For example, as shown in figure 11, when having 2 pendulums 9 on swivel plate 7, if on fixed blade 6 with suitable tooth pitch (referring to here equate with respect to the central angle of the central axis of fixed blade 6), configuration odd number (71) tooth 22 (the high tooth 22h of section and the low tooth 22l of section) of section are in the A of Figure 11 section, at pendulum 9 during near the high tooth 22h of section, in B section, pendulum 9 is positioned at the position of leaving the high tooth 22h of section.That is, 2 pendulums 9 are in identical time point Contact Tooth section 22, thereby swivel plate 7 (driving the motor of swivel plate 7) are not applied large load.

If with example vague generalization shown in Figure 11, when having so N (wherein N is natural number) pendulum 9 on swivel plate 7, individual (wherein with suitable tooth pitch configuration M in fixed blade 6, M is is not the natural number of the multiple of N, be that N and M are the natural numbers of relatively prime relation) tooth section 22, if like this, N pendulum 9 be Contact Tooth section 22 simultaneously not, can not apply large load to swivel plate 7 (driving the motor of swivel plate 7).For example, when having 3 pendulums 9 on swivel plate 7, if on fixed blade 6 with 10 or 11 of suitable tooth pitch configurations tooth section 22,3 pendulums 9 Contact Tooth section 22 simultaneously not so.

The concrete formation of garbage disposer 1 described above is the illustration to embodiments of the present invention, and technical scope of the present invention is not limited to above-mentioned concrete formation.The present invention can freely use, is out of shape or improves and implement in the limit of the scope that does not break away from the technological thought that the scope of the claims puts down in writing.

For example, for the numerical value of the size in the shape of ditch section 21 and tooth section 22, angle illustration only, technical scope of the present invention is not limited to possess the product of described size etc.

In addition, shown the example (with reference to Fig. 2) that uniformly-spaced configures 8 high tooth 22h of section on fixed blade 6 at circumferencial direction, but the quantity of the high tooth 22h of section, the configuration be not limited to this.The quantity of the high tooth 22h of section is not limited to 8.The high tooth 22h of section is as long as configure across interval (being not limited to uniformly-spaced) in the interior week of fixed blade 6, and a plurality of zones that are separated in interior week of fixed blade 6 are got final product.

Perhaps, as shown in figure 12, also the high tooth 22h of section can be configured continuously (between do not arrange low the tooth 22l of section), and in a part (two positions in Figure 12), the continuous zone of the low tooth 22l of section is set.

For material, the manufacture method of fixed blade 6, can select various known materials, method.The material of fixed blade 6 is generally elected metal as, but also can select nonmetals, for example pottery.If cast with lost-wax process, can make at an easy rate with the machining amount of minimum.Perhaps also can lost-wax process and machining is combined, also can cast with sand mo(u)ld, also can the compressed metal powder be shaped, sintering.Also can only make with machining.

In order easily to make fixed blade 6, also can the horizontal cross sectional geometry of tooth section 22 (the high tooth 22h of section, the middle tooth 22m of section, the low tooth 22l of section) be simplified.For example, as shown in figure 13, the one-sided inclined-plane of tooth section 22 also can become vertical with respect to the circular arc 6a that consists of fixed blade 6 (gabarit).Perhaps, though not shown, the inclined-plane of the both sides of tooth section 22 also can become with respect to circular arc 6a vertically.Select such shape, when tilting with respect to circular arc 6a with the inclined-plane, (shape shown in Fig. 5) compared, and makes (casting machining) and becomes easy.

Need to prove, the formation of garbage disposer 1 shown in Figure 1 is " conceptual formation ", has omitted unnecessary inscape in explanation of the present invention, such as the diagram of nexus element (bolt, nut), bearing, sealing etc.In addition, also omitted the diagram of garbage disposer 1 with the detailed formation of the installation portion of kitchen sink 2.The feature of the having or not of the inscape that these are not shown, its form can only be said the explanation that does not affect technical scope of the present invention.

Need to prove, the application is based on No. 2010-210199, the Japan's patent application that proposed on September 17th, 2010.With reference to manual, the scope of Patent right requirement, the accompanying drawing of No. 2010-210199, Japan's patent application, all introduce in this manual.
