Description

  The present invention relates to a manual rotary drainer that can be attached to a drain of a kitchen sink in a home, etc., and can easily drain off garbage such as leftovers and tea waste containing moisture by centrifugal force. .

In recent years, kitchen sinks have a mainstream structure in which a garbage storage basket is detachably attached to a drain outlet, and a drain pipe is connected to the lower side of the garbage storage basket. According to this structure, wastewater containing solids (raw garbage) such as chips from cooking that has been discharged in the sink has flowed into the garbage storage basket, and only solids larger than the mesh of the garbage storage basket Is drowned in the garbage storage basket, and the moisture flows out to the drain pipe side by gravity.
However, the moisture contained in the garbage collected from the garbage storage basket does not flow sufficiently to the outside of the garbage receiver due to its surface tension, etc., and the garbage is stored in the garbage receiver in a state containing a lot of moisture. . Therefore, if you put this garbage in the garbage bag and put it out to the garbage collection place, the garbage will be very heavy because it contains a lot of moisture, and its volume will increase. Water with a foul odor dripped from the bag, which was very painful.
Moreover, even if a draining net or the like is attached to the garbage storage basket, clogging occurs, and there are many cases where water is not sufficiently cut out at the time of disposal.
In order to solve this problem, for example, in (Patent Document 1), a sink sink in which a drain pipe is provided at a lower part of a drain port via a dust storage part, and a detachable and rotatable arrangement in the dust storage part. There is disclosed a sink centrifugal dewatering device having a water permeable waste storage means and a rotating means for rotating the waste storage means.

JP-A-6-320048

However, the above conventional technique has the following problems.
(1) In the device disclosed in Patent Document 1, when dewatering the trash stored in the trash storage means disposed in the trash storage section, the trash storage means is drained by rotating the trash storage means with the rotation means. The rotating means is disposed on the drain outlet of the sink, and is rotated by hooking a key-like claw on the dust storage means in the dust storage section.
(2) Therefore, in (Patent Document 1), it is not necessary to perform a special work on the current sink, the dehydration work can be easily performed manually, there is no vibration and noise, and there is no need for measures against water leakage and leakage. there were.
(3) However, the manual rotation device (rotating means) of (Patent Document 1) includes a base body set so as to cover the drain outlet of the sink, and a rotary shaft rotatably supported on a horizontal plane on the base body. And a pushing portion for rotationally driving the rotating shaft. When the manual rotating device is attached to the dust storage means, the drain port is covered with the manual rotating device. Since the rotating shaft and pusher part of the pump will protrude greatly above the drainage port, it is necessary to remove the manual rotating device when cooking or washing, unless the manual rotating device is frequently attached or detached. In addition, a storage space for the manual rotation device is also required, which has a problem that it is unsanitary and lacks handleability and space saving.
(4) Further, since the manual rotating device is attached and detached, a mechanism portion for rotating the dust storage means by the manual rotating device is exposed, and there is a problem that handling and durability are lacking.

  The present invention solves the above-mentioned problems, and can be easily attached to the drainage outlet by replacing it with a garbage storage basket attached to the drainage outlet of the kitchen sink in the home, etc. without performing processing or construction. There is nothing protruding above the drainage port, it is compact and space-saving, and it is possible to drain the garbage such as leftovers and tea waste containing water easily and reliably and collect it in a garbage bag. It is excellent in labor saving and energy saving, and it prevents the water with bad smell from dripping from the garbage bag and keeps the kitchen and the garbage collection place clean, and it is hygienic and easy to handle. The purpose is to provide a rotary drainer.

Means for solving the problems, and actions and effects obtained thereby

In order to solve the above-described problems, a manual rotary drainer / drainage device of the present invention has the following configuration.
A manual rotary drainer according to claim 1 of the present invention is a manual rotary drainer provided in a sink outlet, and is associated with a stepped locking portion on the outer periphery of the drain outlet. An outer basket having a collar portion to be stopped; an inner basket that is detachably inserted in the outer basket and rotatably held; and the inner basket that is formed in the inner basket and rotates with respect to the outer basket. And a manual rotation mechanism.
This configuration has the following operations and effects.
(1) An outer cage having a hook portion engaged with a stepped engagement portion on the outer periphery of the drainage port, an inner cage that is detachably inserted into the outer cage and is rotatably held, and an inner cage shape Because it has a manual rotation mechanism that rotates the inner basket with respect to the outer basket, the garbage such as leftovers and tea waste containing moisture stored in the inner basket simply by rotating the inner basket with the manual rotation mechanism The water can be drained easily and reliably, and the separated water can be drained from the outer basket to the drain outlet, which is hygienic and has excellent drainage and drainage reliability.
(2) Since the outer basket has a collar portion that is locked to the stepped locking portion on the outer periphery of the sink drain port, it can be easily mounted using the existing sink as it is, No work is required, and it is easy to handle and work.
(3) Since the inner basket is detachably held on the outer basket, when the garbage is drained and discarded (collected), only the inner basket is removed and the garbage is disposed of easily. It is easy to handle and saves labor when processing garbage.
(4) Since the outer and inner baskets are detachable from the drain and the outer basket, respectively, the drain and the outer and inner baskets can be easily cleaned and cleaned, and are hygienic, easy to maintain and handle. Excellent.
(5) Since the inner basket is rotatably held by the outer basket, after applying detergent or bleach to the inner basket, the inner basket is rotated by a manual rotation mechanism, so that the outer basket is also cleaned or bleached. It is possible to perform cleaning efficiently by spreading agents and the like, and it is excellent in cleaning efficiency and workability.
(6) Since the manual rotation mechanism is formed in the inner basket, the manual rotation mechanism and the inner basket can be handled integrally, and the mechanism portion of the manual rotation mechanism can be protected by the inner basket. The mechanism part is not exposed to the outside, the mechanism part can be prevented from being damaged, and the handleability, maintainability and durability are excellent.
(7) Since the manual rotation mechanism is formed in the inner basket and does not protrude above the drain, the manual rotation mechanism does not get in the way when cooking or washing, and space saving. Excellent handleability.

Here, as the material of the outer basket and the inner basket, synthetic resins such as polycarbonate, polypropylene, and polyethylene are preferably used. This is because it is lightweight and has excellent moldability and mass productivity.
A plurality of drain holes are formed in the peripheral wall surface of the inner basket. The diameter of the drain hole is preferably 1.5 mm to 4 mm. As the hole diameter of the drainage hole becomes smaller than 1.5 mm, the water breakage tends to become worse and clogging tends to occur. As the hole diameter becomes larger than 4 mm, the solid content of the garbage easily passes through the drainage hole. There is a tendency for the efficiency to decrease, both of which are not preferred.
The outer basket can support the inner basket and the manual rotation mechanism and has a structure that can withstand the load during rotation of the inner basket, but the drained water is not drained without stagnation. It is necessary to form a drain hole at least on the bottom so that the water is drained from the mouth. The size, shape, arrangement, etc. of the drain holes can be selected as appropriate.
Moreover, you may perform an antibacterial process, a disinfection process, etc. suitably so that the water permeability (drainage property) of an inner basket and an outer basket may fall, and a slime etc. may not generate | occur | produce.

The manual rotation mechanism may be any mechanism that can rotate the inner basket with respect to the outer basket, but it is preferable that the manual rotation mechanism be formed in the inner basket so as not to protrude above the outer basket. In particular, the manual rotation mechanism is shaped so that it fits inside the outer basket, so that even if the manual rotary drainer is attached to the drain, there are no protrusions above the drain and the sink is used effectively. It can be used and has excellent usability.
The inner basket may be rotated in only one direction relative to the outer basket, or may be rotated in both directions (forward / reverse rotation).

The device according to claim 2 is the manual rotary drainer / drainage device according to claim 1, wherein the manual rotation mechanism includes a cylindrical fitting portion formed on an axis of the inner cage, A serrated locking portion formed continuously along the inner periphery of the cylindrical fitting portion, a cylindrical rotating body inserted through the cylindrical fitting portion, and a peripheral portion of the cylindrical rotating body. A key claw portion that is movably held, a biasing spring that is disposed on the cylindrical rotating body and that biases the key claw portion to engage with the serrated locking portion, and the cylindrical rotating body A rotating body spiral groove formed on the inner peripheral surface of the rotating body projection or a rotating body protrusion protruding from the inner peripheral surface of the cylindrical rotating body, a sliding shaft inserted through the hollow portion of the cylindrical rotating body, A sliding shaft protrusion protruding from the outer peripheral surface of the sliding shaft and loosely fitted in the rotating spiral groove, or a sliding shaft formed on the outer peripheral surface of the sliding shaft and loosely fitting the rotating protrusion. Spiral A push button formed on the upper end of the sliding shaft, and a lower end side that is extrapolated to the sliding shaft abuts on an upper end portion of the cylindrical fitting portion, and an upper end side abuts on a lower end portion of the push button. A coil spring, wherein the cylindrical fitting portion is loosely fitted into a bottomed cylindrical inner cage holding recess formed at the axial center of the outer cage.
With this configuration, in addition to the same operations and effects as in claim 1, the following operations and effects are provided.
(1) A manual rotation mechanism includes a cylindrical fitting portion formed at the center of the inner cage, a sawtooth locking portion formed continuously along the inner periphery of the cylindrical fitting portion, and a cylinder A cylindrical rotating body that is inserted into the cylindrical fitting, a hook claw that is swingably held on the outer periphery of the cylindrical rotating body, and a key claw that is disposed on the cylindrical rotating body and has a serrated engagement An urging spring for urging to engage the rotating part, and a rotating body spiral groove formed on the inner peripheral surface of the cylindrical rotating body or a rotating body protrusion protruding from the inner peripheral surface of the cylindrical rotating body; , Formed on the outer peripheral surface of the sliding shaft inserted into the hollow portion of the cylindrical rotating body, the sliding shaft protrusion protruding from the outer peripheral surface of the sliding shaft, or loosely fitted in the rotating body spiral groove And a sliding shaft spiral groove into which the rotating body protrusion is loosely fitted, and a push button formed at the upper end portion of the sliding shaft, and a cylindrical fitting portion is formed at the bottom of the outer cage axis. It is loosely fitted into the cylindrical inner cage holding recess. Therefore, just by pressing down the push button, the sliding shaft moves downward and the cylindrical rotating body rotates, and at this time, the lock claw part engages with the serrated locking part, so that The basket rotates and drains the moisture of the garbage stored in the inner basket, which is excellent in draining reliability and efficiency.
(2) Since the manual rotation mechanism has a coil spring that is extrapolated to the sliding shaft and whose lower end abuts on the upper end of the cylindrical fitting portion and whose upper end abuts on the lower end of the push button, the push button is depressed to drain the water. After releasing the push button, when the hand is released from the push button, the compressed coil spring repels, the push button is pushed upward and automatically returns to the initial state, so that it can be drained repeatedly. Excellent drainage workability and reliability.
(3) A manual rotation mechanism includes a cylindrical fitting portion formed at the center of the inner cage, a sawtooth locking portion formed continuously along the inner periphery of the cylindrical fitting portion, and a cylinder A cylindrical rotating body that is inserted into the cylindrical fitting, a hook claw that is swingably held on the outer periphery of the cylindrical rotating body, and a key claw that is disposed on the cylindrical rotating body and has a serrated engagement An urging spring for urging to engage the rotating part, and a rotating body spiral groove formed on the inner peripheral surface of the cylindrical rotating body or a rotating body protrusion protruding from the inner peripheral surface of the cylindrical rotating body; , Formed on the outer peripheral surface of the sliding shaft inserted into the hollow portion of the cylindrical rotating body, the sliding shaft protrusion protruding from the outer peripheral surface of the sliding shaft, or loosely fitted in the rotating body spiral groove By having the sliding shaft spiral groove in which the rotating body protrusion is loosely fitted, the cylindrical rotating body rotates in the reverse direction when the push button is pushed up by the repulsion of the coil spring and the sliding shaft moves upward after draining. , The hooking portion is pushed back in the axial direction of the cylindrical rotating body by the projection of the serrated locking portion and the urging spring is compressed, so that the locking hook portion does not engage with the sawtooth locking portion. Since only the cylindrical rotating body is idled and the inner basket does not rotate, the garbage stored in the inner basket rotates in the opposite direction and does not scatter inside the inner basket. It can be drained repeatedly and is excellent in drainage reliability. In addition, since the inner basket does not reversely rotate, it is possible to keep the garbage attached to the inner peripheral surface of the inner basket after draining. Excellent in labor saving.
(4) The manual rotation mechanism includes a cylindrical fitting portion formed on the axis of the inner cage, and the cylindrical fitting portion holds the cylindrical inner cage with a bottom formed on the axis of the outer cage. Since it is loosely fitted in the recess, the inner cage can be rotated with a small force against the outer cage, and draining can be easily performed using centrifugal force. Power is not required, and energy saving and quietness are excellent. Further, it is possible to easily remove the garbage by simply lifting the inner basket upward and recovering garbage, and to clean and maintain the inner and outer baskets, which is excellent in usability and handling.

Here, the cylindrical fitting portion formed in the axial center of the inner basket is loosely fitted in the bottomed cylindrical inner cage holding recess formed in the axial center of the outer basket, so that the inner basket is attached to the outer cage. Removably and rotatably held.
A serrated locking portion is formed continuously along the inner periphery of the cylindrical fitting portion, and the key claw portion held swingably on the outer peripheral portion of the cylindrical rotating body is serrated by a biasing spring. When the push button is pushed down and the cylindrical rotating body rotates in the forward direction by being biased so as to engage with the part, the key claw part engages with the serrated locking part to rotate the cylinder. The inner cage rotates together with the body, but when the push button is pushed up and the cylindrical rotating body rotates in the reverse direction, the key claw is pushed in the axial direction of the cylindrical rotating body by the projection of the serrated locking portion. Since the biasing spring is returned and compressed, the key claw portion does not engage with the serrated locking portion, and the inner basket does not rotate.
It is preferable that 2 to 4 key claws are arranged at equal angular intervals in the circumferential direction of the cylindrical rotating body. If there is one key claw part, the rotational force of the cylindrical rotating body is not uniformly transmitted to the inner basket, and the inner basket tends to be difficult to rotate smoothly, and the structure becomes more complicated as the number increases more than four. There is a tendency that it becomes difficult to dispose the nail portion, which is not preferable. By arranging 2 to 4 key claw parts at equal angular intervals in the circumferential direction of the cylindrical rotating body, the rotational force of the cylindrical rotating body is evenly transmitted to the inner basket and the inner basket rotates smoothly. Can be made.

When the rotating body spiral groove is formed on the inner peripheral surface of the cylindrical rotating body, and the sliding shaft protrusion projecting on the outer peripheral surface of the sliding shaft is loosely fitted in the rotating body spiral groove, the push button is pushed down to slide. When the moving shaft is moved downward, the sliding shaft protrusion moves down, so that the rotating body spiral groove moves along the sliding shaft protrusion, and the cylindrical rotating body rotates. In this case, the sliding shaft protrusion is formed so as to move from the upper end side to the lower end side of the cylindrical rotating body.
When the rotating body protrusion is projected on the inner peripheral surface of the cylindrical rotating body and the rotating body protrusion is loosely fitted in the sliding shaft spiral groove formed on the outer peripheral surface of the sliding shaft, the push button is pushed down to slide. When the moving shaft is moved downward, the sliding shaft spiral groove descends, so that the rotating body protrusion moves along the sliding shaft spiral groove, and the cylindrical rotating body rotates. In this case, the rotating body protrusion is formed on the lower end side of the cylindrical rotating body.
It is preferable to arrange 2 to 4 sliding shaft protrusions or rotating body protrusions at equal angular intervals in the circumferential direction of the sliding shaft or cylindrical rotating body. If there is only one sliding shaft projection or rotating body projection, the straight movement of the sliding shaft tends to be difficult to convert smoothly into the rotational movement of the cylindrical rotating body, and the structure becomes more complex as the number of sliding shaft projections increases. Therefore, it is difficult to form the rotating body spiral groove or the sliding shaft spiral groove in which the sliding shaft protrusion or the rotating body protrusion is loosely fitted. Two to four sliding shaft protrusions or rotating body protrusions are arranged at equiangular intervals in the circumferential direction of the sliding shaft or cylindrical rotating body, and the cylindrical rotating body or sliding shaft is correspondingly arranged. By forming 2 to 4 rotating body spiral grooves or sliding shaft spiral grooves on the outer periphery, the linear motion of the sliding shaft is smoothly converted into the rotational motion of the cylindrical rotating body, and the cylindrical rotating body Can be rotated efficiently.

The push button may be formed integrally with the sliding shaft, or may be formed as a separate member and fixed to the upper end of the sliding shaft by means such as screwing, fitting, or adhesion.
Push button so that when the push button is pushed down, the upper end of the coil spring extrapolated to the sliding shaft comes into contact with the lower surface of the push button and the coil spring is compressed between the push button and the cylindrical fitting portion. The outer shape of is formed larger than the diameter of the sliding shaft. Since the push button can compress the coil spring, its outer shape can be selected as appropriate, and may be a polygon other than a circle.

The device according to claim 3 is the manual rotary drainage drainage device according to claim 1 or 2, wherein the manual rotation mechanism is a ball bearing disposed at the bottom of the cylindrical rotating body, A thrust washer disposed on the upper surface of the bottom of the inner basket holding recess and contacting the lower end surface of the cylindrical fitting portion.
With this configuration, the following functions and effects are provided in addition to the functions and effects of the first or second aspect.
(1) The manual rotation mechanism has a ball bearing disposed at the bottom of the cylindrical rotating body and a thrust washer disposed on the bottom upper surface of the inner cage holding recess and abutting against the lower end surface of the cylindrical fitting portion. This reduces friction between the lower end surface of the cylindrical rotating body and the cylindrical fitting portion and the upper surface of the bottom portion of the inner cage holding recess, and smoothly rotates the cylindrical rotating body and the inner cage with respect to the outer basket. It is excellent in stability and certainty of operation.

  Here, the ball bearing may be in direct contact with the upper surface of the bottom of the inner cage holding recess, or may be in contact with the upper surface of the thrust washer. Friction between the cylindrical rotating body and the inner cage holding recess can be reduced, and draining efficiency is excellent.

A device according to a fourth aspect of the present invention is the manual rotary drainer according to any one of the first to third aspects, wherein the device is disposed on the bottom surface of the outer basket and supports the bottom surface of the inner basket. And an inner basket receiving roller.
With this configuration, in addition to the operation and effect of any one of claims 1 to 3, the following operation and effect are provided.
(1) By having an inner basket receiving roller disposed on the bottom surface of the outer basket and supporting the bottom surface of the inner basket, the entire bottom surface of the inner basket is prevented from coming into contact with the bottom surface of the outer basket. The inner basket can be rotated smoothly, and drainage is reliable and efficient.

  Here, although the number and arrangement | positioning of an inner basket receiving roller can be selected suitably, the number of the inner basket receiving rollers arrange | positioned on the same periphery is 3-6 pieces. As the number of inner basket receiving rollers is less than three, it becomes difficult to uniformly support the entire bottom surface of the inner basket, and the inner basket tends to tilt. As the number of inner basket receiving rollers increases, the arrangement of the inner basket receiving rollers is increased. There is a tendency that the interval becomes narrow and the mass productivity and durability of the outer basket tend to be lowered, both of which are not preferable. By arranging the inner basket receiving rollers at equal angular intervals on the same circumference, the entire inner basket can be uniformly supported by the inner basket receiving rollers, and the inner basket may be tilted while the inner basket is rotating. And stable operation. In addition, when the inner basket receiving rollers are disposed twice on the circumferences having different diameters, the inner basket receiving rollers are arranged by staggering the positions of the inner basket receiving rollers on the inner side and the outer side by shifting the circumferential direction. The entire bottom surface of the inner basket can be uniformly supported by many inner basket receiving rollers without being close to each other, and the support stability of the inner basket is excellent.

The outer basket of the manual rotary drainer 1 that is detachably attached to the mouth 20a, 2a is the bottom surface of the outer basket 2, 2b is the cylindrical peripheral wall of the outer basket 2, and 2c is formed on the outer periphery of the upper end of the peripheral wall 2b. A flange portion of the outer basket 2 that is locked to the step-shaped locking portion 20b of the drain port 20a, 3 is a bottomed cylindrical inner cage holding recess formed at the axis of the outer cage 2, and 3a is an inner cage holding An extending portion formed in a cylindrical shape above the concave portion 3, 3 b is a through hole formed in the central portion of the inner cage holding concave portion 3, and 4 is the same circle at equal angular intervals on the bottom surface portion 2 a of the outer cage 2. Four inner basket receiving rollers arranged on the circumference, 5 are polycarbonate and poly The inner cage 5a of the manual rotary drainer 1 is formed by a synthetic resin such as pyrene and is detachably inserted in the outer cage 2 and held rotatably. The bottom surface 5b of the inner basket 5 is a cylindrical peripheral wall of the inner basket 5, 6 is a manual rotation mechanism that is formed in the inner basket 5 and rotates the inner basket 5 with respect to the outer basket 2, and 7 is the inner cage 5. A cylindrical fitting portion of the manual rotation mechanism 6 formed on the shaft center and loosely fitted in the inner cage holding recess 3, 8 is an outer cylinder portion of the manual rotation mechanism 6 formed on the outer periphery of the cylindrical fitting portion 7. , 9 is formed between the cylindrical fitting portion 7 and the outer cylindrical portion 8, and the outer peripheral concave portion of the manual rotation mechanism 6 in which the extending portion 3 a of the inner cage holding concave portion 3 is loosely fitted. 10 is the cylindrical fitting portion 7 is a cylindrical rotating body of the manual rotating mechanism 6 inserted inside 7, and 11 is a double rotation of the manual rotating mechanism 6 formed on the inner peripheral surface of the cylindrical rotating body 10. The body spiral groove 14 is a sliding shaft of the manual rotation mechanism 6 inserted through the hollow portion of the cylindrical rotating body 10, and 14 a is provided on the outer peripheral surface of the sliding shaft 14 so as to protrude at an interval of 180 degrees. The two sliding shaft protrusions of the manual rotation mechanism 6 that are loosely fitted to each other, 15 is a push button of the manual rotation mechanism 6 formed on the upper end of the sliding shaft 14, and 16 is on the sliding shaft 14. A coil spring 16a of the manual rotation mechanism 6a, the lower end side of which is attached to the upper surface of a washer 17 disposed on the upper end portion of the cylindrical fitting portion 7 and the upper end side of which is in contact with the lower end portion of the push button 15, 16a is a sliding shaft. 14 is a push-down restricting cylinder that is inserted between 14 and the coil spring 16 and restricts the amount of push button 15 to be pushed down, 18 is a ball bearing disposed at the bottom of the cylindrical rotating body 10, and 19 is the bottom upper surface of the inner cage holding recess 3. The thrust that is disposed on the lower end surface of the cylindrical fitting portion 7 and abuts on the ball bearing 18 It is a washer.

  In the present embodiment, four inner basket receiving rollers 4 are arranged on the same circumference at equal angular intervals. As a result, the entire inner basket 5 can be uniformly supported by the inner basket receiving roller 4, and the inner basket 5 does not tilt during the rotation of the inner basket 5, and the operation stability is excellent. In addition, the number and arrangement | positioning of the inner basket receiving roller 4 can be selected suitably. When the inner basket receiving rollers 4 are arranged on the same circumference, the number of the inner basket receiving rollers 4 is preferably 3 to 6. As the number of the inner basket receiving rollers 4 becomes smaller than three, it becomes difficult to uniformly support the entire bottom surface 5a of the inner basket 5, and the inner basket 5 tends to be inclined, and as the number of the inner baskets becomes larger than six, the inner basket is increased. This is because the arrangement interval of the receiving rollers 4 becomes narrow, and the mass productivity and durability of the outer basket 2 tend to be lowered. Further, when the inner basket receiving rollers 4 are arranged in a double manner on the circumferences having different diameters, the inner basket receiving rollers 4 are alternately arranged by shifting the circumferential positions of the inner basket receiving rollers 4 on the inner side and the outer side. The entire bottom surface 5a of the inner basket 5 can be uniformly supported by the many inner basket receiving rollers 4 without the rollers 4 being close to each other, and the support stability of the inner basket 5 is excellent.

A plurality of drain holes (not shown) having a hole diameter of 1.5 mm to 4 mm were formed in the peripheral wall 5b of the inner cage 5. As the hole diameter of the drainage hole becomes smaller than 1.5 mm, the water breakage tends to become worse and clogging tends to occur. As the hole diameter becomes larger than 4 mm, the solid content of the garbage easily passes through the drainage hole. This is because it has been found that the efficiency tends to decrease. In addition, the number and arrangement | positioning of a drain hole can be selected suitably.
Further, the outer cage 2 may support the inner cage 5 and the manual rotation mechanism 6, and may have a structure capable of withstanding a load during rotation of the inner cage 5 and a pressing force of the push button 15. By providing ribs on the peripheral wall 2b of the outer basket 2, the shape stability of the outer basket 2 is excellent, and deformation and breakage can be effectively prevented. By forming a drain hole in at least the bottom surface portion 2a of the outer basket 2, the water drained by the inner basket 5 is drained from the drain port 20a without stagnation inside the outer basket 2 and is excellent in terms of hygiene. The size, shape, arrangement, etc. of the drain holes can be selected as appropriate.
Further, in the present embodiment, the cylindrical fitting portion 7 is loosely fitted inside the inner basket holding concave portion 3, and the outer peripheral concave portion 9 formed between the cylindrical fitting portion 7 and the outer cylindrical portion 8 is internally inserted. The extended portion 3a of the cage holding recess 3 was loosely fitted. Thereby, the position shift and inclination of the inner cage 5 with respect to the outer cage 2 can be effectively prevented, and the holding stability of the inner cage 5 is excellent.

Next, details of the manual rotation mechanism in the manual rotary drainer according to the first embodiment will be described based on the operation.
FIG. 2 is a schematic cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a schematic plan view of a rotating spiral groove in the cylindrical rotating body of the manual rotary drainer / drainage device of the first embodiment.
In FIG. 3, 11 a is a lower side of the rotating body spiral groove 11, 11 b is an upper side of the rotating body spiral groove 11, and 11 c is a belt-like shape connecting the two rotating body spiral grooves 11 at the lower end of the cylindrical rotating body 10. The idle play groove is formed in the hatching, and the hatched portion indicates the groove.
First, when draining water, the push button 15 of the manual rotation mechanism 6 is pushed down manually.
As shown in FIGS. 1 and 2, the sliding shaft protrusion 14 a protruding from the outer peripheral surface of the sliding shaft 14 is loosely fitted in the rotating body spiral groove 11 formed on the inner peripheral surface of the cylindrical rotating body 10. Therefore, when the push button 15 is pushed down and the slide shaft 14 is moved downward, the slide shaft projection 14a is lowered, so that the slide shaft projection as shown by the solid line arrow in FIG. The portion 14a moves relatively along the lower side 11a of the rotating body spiral groove 11, and the cylindrical rotating body 10 rotates in the normal direction (left rotation). At this time, even if the push button 15 is pushed down, the cylindrical rotating body 10 tries to continue to rotate with momentum, but as shown in FIG. 3, the idle rotation idle groove 11c is formed at the lower end of the cylindrical rotating body 10. Therefore, the sliding shaft protrusion 14a does not hinder the rotation of the cylindrical rotating body 10 while the push button 15 is pressed down, and the cylindrical rotating body 10 continues to rotate with inertia. Since the push-down restricting cylinder 16a is inserted between the sliding shaft 14 and the coil spring 16, the upper end of the push-down restricting cylinder 16a is placed on the lower end of the push button 15 when the push button 15 is pushed down by a predetermined amount. It is possible to regulate the amount of push-down of the push button 15 by abutting, preventing a large load from being applied to the outer basket 2 and the inner basket 5 and preventing damage.

In the present embodiment, two sliding shaft protrusions 14 a are arranged on the outer periphery of the sliding shaft 14 at intervals of 180 degrees, and the two rotating body spiral grooves 11 are formed on the outer periphery of the cylindrical rotating body 10 correspondingly. Formed. Thereby, the rectilinear motion of the sliding shaft 14 can be smoothly converted into the rotational motion of the cylindrical rotating body 10, and the cylindrical rotating body 10 can be efficiently rotated with a small force. The number of sliding shaft protrusions 14a can be appropriately selected from 2 to 4. If there is only one sliding shaft protrusion 14a, it is difficult to smoothly convert the straight movement of the sliding shaft 14 into the rotational movement of the cylindrical rotating body 10, and the structure becomes complicated as the number of sliding shaft protrusions 14a increases. This is because it tends to be difficult to form the rotating spiral groove 11 in which the sliding shaft protrusion 14a is loosely fitted.
Instead of forming the rotating body spiral groove 11 on the inner peripheral surface of the cylindrical rotating body 10 and projecting the sliding shaft protrusion 14 a on the outer peripheral surface of the sliding shaft 14, the inner periphery of the cylindrical rotating body 10 is provided. A rotating body protrusion may be provided on the surface to form a sliding shaft spiral groove on the outer peripheral surface of the sliding shaft 14.
In the present embodiment, the push-down restricting cylinder 16 a is inserted between the sliding shaft 14 and the coil spring 16, but may be inserted through the outer periphery of the coil spring 16.

4 is a schematic cross-sectional view taken along the line B-B in FIG. 1, and FIG. 5A is an operation of the key claw portion at the time of forward rotation in the manual rotation mechanism of the manual rotary drainer / drainage device of the first embodiment. FIG. 5B is an enlarged schematic view of the main part showing the operation of the key claw part during reverse rotation in the manual rotation mechanism of the manual rotary drainer / drainage device of the first embodiment. is there.
4 and 5, 7 a is a sawtooth locking portion of the manual rotation mechanism 6 formed continuously along the inner periphery of the cylindrical fitting portion 7, and 7 b is a protrusion of the sawtooth locking portion 7 a. , 12 are two lock claws of the manual rotation mechanism 6 disposed on the outer periphery of the cylindrical rotating body 10 at intervals of 180 degrees, and 12a is swingable with respect to the cylindrical rotating body 10 with respect to the lock rotating claw section 12. Reference numeral 13 designates a biasing spring of the manual rotation mechanism 6 that is disposed on the cylindrical rotating body 10 and biases the key claw portion 12 so as to engage with the serrated locking portion 7a.
As indicated by the solid line arrow in FIG. 5 (a), when the cylindrical rotating body 10 rotates in the forward direction (counterclockwise), the key claw portion 12 urged by the urging spring 13 is engaged with the serrated locking portion 7a. Accordingly, the inner cage 5 formed integrally with the cylindrical fitting portion 7 rotates with respect to the outer cage 2 as the cylindrical rotating body 10 rotates. Thereby, food waste such as leftover rice and tea residue containing water stored in the inner basket 5 is drained, and the separated water can be drained from the outer basket 2 to the drain port 20a.

Next, when the hand is released from the push button 15, the compressed coil spring 16 is repelled, so that the push button 15 is pushed up and the slide shaft 14 moves upward. At this time, as the sliding shaft protrusion 14a rises, the sliding shaft protrusion 14a relatively moves along the upper side 11b of the rotating body spiral groove 11 as shown by the broken arrow in FIG. The cylindrical rotating body 10 rotates in the reverse direction (right rotation).
When the cylindrical rotating body 10 rotates in the reverse direction (right rotation) as indicated by the broken arrow in FIG. 5B, the key claw portion 12 rotates in the cylindrical shape by the projection 7b of the serrated locking portion 7a. Since the pushing spring 13 is pushed back in the axial direction of the body 10 and the urging spring 13 is compressed and the key claw portion 12 does not engage with the serrated locking portion 7a, only the cylindrical rotating body 10 rotates freely, The basket 5 automatically returns to the initial state without rotating.
By repeating the above operation a plurality of times, it is possible to reliably drain the garbage stored in the inner basket 5.

In the present embodiment, the two key claws 12 are arranged on the outer periphery of the cylindrical rotating body 10 every 180 degrees. Thereby, the rotational force of the cylindrical rotating body 10 can be evenly transmitted to the inner cage 5 to smoothly rotate the inner cage 5. In addition, the number of the key nail | claw parts 12 can be suitably selected from 2-4 pieces. When the number of the key claw portions 12 is one, the rotational force of the cylindrical rotating body 10 is not uniformly transmitted to the inner cage 5, and the inner cage 5 tends to be difficult to rotate smoothly. This is because it tends to be complicated and it becomes difficult to arrange the key claw portion 12. The push button 15 may be formed integrally with the sliding shaft 14 or may be formed as a separate member and fixed to the upper end of the sliding shaft 14 by means such as screwing, fitting, or adhesion.
When the push button 15 is pushed down, the upper end portion of the coil spring 16 inserted on the slide shaft 14 comes into contact with the lower surface of the push button 15, and the coil spring 16 is compressed between the push button 15 and the cylindrical fitting portion 7. As shown, the outer shape of the push button 15 is formed larger than the diameter of the sliding shaft 14. Since the push button 15 only needs to compress the coil spring 16, the outer shape can be selected as appropriate, and may be a polygon other than a circle.
The serrated locking portion 7a and the key claw portion 12 are omitted, and the cylindrical rotating body 10 and the cylindrical fitting portion 7 are integrated, or the cylindrical rotating body 10 and the key claw portion 12 are omitted. The inner cage 5 can also be rotated forward and backward directly by loosely fitting the sliding shaft protrusion 14a of the sliding shaft 14 into a spiral groove formed on the inner peripheral surface of the cylindrical fitting portion 7.
