Detailed Description

Example 1

The present embodiment provides a residual liquid treatment mechanism, please refer to fig. 1 to 10, which includes a cup 2 and a movable member 4.

Referring to fig. 5, the cup 2 includes a receiving chamber 201 located above, a draining chamber 202 located below, and a transition chamber 203 connecting the receiving chamber 201 with the draining chamber 202, the draining chamber 202 being adapted to communicate with an inlet of an anti-siphon structure.

Referring to fig. 2 to 4, 7, 9 and 10, the movable member 4 is installed in the transition chamber 203. The movable member 4 is driven by the driving mechanism to move, and can be switched between an open state and a closed state: in the open state, the movable member 4 communicates the accommodation chamber 201 with the liquid discharge chamber 202; in the closed state, the mobile 4 intercepts the containing chamber 201 from the draining chamber 202.

In the residual liquid treatment mechanism of the embodiment, if the solution in the washing cavity 10 above the residual liquid treatment mechanism needs to be discharged in the actual use process, the movable piece 4 is driven by the driving mechanism to move so as to be in an open state, and the accommodating cavity 201 is communicated with the liquid discharge cavity 202; the siphon structure communicated with the liquid discharge cavity 202 is opened, and the solution in the washing cavity 10 flows into the liquid discharge cavity 202 through the accommodating cavity 201 and is discharged through the siphon structure; when the solution in the washing chamber 10 is discharged, the movable member 4 moves to be in a closed state, and the accommodating chamber 201 and the drain chamber 202 are blocked, even if the anti-siphon structure sucks air without sucking the liquid in the drain chamber 202, the residual solution is blocked in the drain chamber 202 and does not reversely flow into the accommodating chamber 201 to enter the washing chamber 10, thereby ensuring that no liquid remains in the washing chamber 10, and avoiding bacteria and odor in the washing chamber 10.

Preferably, the movable member 4 is reciprocally slidably arranged within the transition chamber 203 to switch the movable member 4 between said open and said closed state. That is, the movable member 4 is driven by the driving mechanism to slide in the transition chamber 203 to switch between the open state and the closed state.

For example, the driving mechanism drives the movable piece 4 to be inserted into the transition cavity 203, and a hard seal is formed between the outer peripheral wall of the movable piece 4 and the inner peripheral wall of the transition cavity 203, so that the movable piece 4 is in a closed state; in contrast, the driving mechanism drives the movable member 4 out of the transition chamber 203, releasing the sealing connection between the movable member 4 and the transition chamber 203, and thus placing the movable member 4 in an open state.

As a preferred embodiment, as shown in fig. 7, the movable member 4 includes a main body portion 41 slidably provided in the transition chamber 203 and a sealing portion 42 fixed to the outer peripheral rim of the main body portion 41; in the open state, the sealing portion 42 is separated from the transition chamber 203; in the closed state, the sealing portion 42 seals against the inlet end or the inner wall surface of the transition chamber 203.

Preferably, the seal portion 42 is a generally soft seal to elastically accommodate the assembly gap while ensuring tightness. For example, the soft sealing body is a sealing ring, or other sealing strips wound around the outer periphery of the main body 41.

Preferably, as shown in fig. 7, the sealing portion 42 is provided on the body portion 41 at a first end on the side close to the accommodation chamber 201; the sealing part 42 extends into the accommodating cavity 201; as shown in fig. 9, in the closed state, the sealing portion 42 sealingly overlaps the end face of the inlet end of the transition chamber 203; correspondingly, in the open state, the driving mechanism drives the movable piece 4 to integrally slide towards the accommodating cavity 201, and the sealing part 42 is separated from the end face of the inlet end of the transition cavity 203.

There are various fixing methods between the sealing portion 42 and the main body portion 41, for example, an annular clamping groove is provided on the outer peripheral wall of the main body portion 41, the inner side end of the sealing portion 42 is tightly clamped in the annular clamping groove, and the outer side end of the sealing portion 42 is used for sealing connection with the end face of the inlet end of the transition cavity 203 or the inner wall surface of the transition cavity 203. Alternatively, it may be bonded to the main body 41 by other means, such as by a waterproof adhesive.

In order to facilitate the installation of the seal portion 42, as shown in fig. 7, it is further preferable that the movable member 4 further includes a lap portion 43 fixed to a periphery of the main body portion 41, the seal portion 42 being provided to the main body portion 41 by being provided to the lap portion 43, and in the closed state, the seal portion 42 being clamped to an end face of the lap portion 43 and an inlet end of the accommodation chamber 201, so that the seal portion 42 is further deformed by pressing, enhancing the sealing effect.

There are various fixing methods of the seal portion 42 to the joint portion 43, and the above-described annular groove method or the waterproof sealant bonding method may be used.

As a further preferred embodiment, referring to fig. 4 and 7, an end surface of the main body 41 on a side facing the liquid discharge chamber 202 is provided with an inwardly recessed hollow chamber 410, and the hollow chamber 410 communicates with the liquid discharge chamber 202; in the closed state, the hollow cavity 410 is truncated with the containing cavity 201; in the open state, the accommodating chamber 201 is communicated with the hollow chamber 410 through at least one liquid drain 411 provided in the main body 41, so that the washing liquid in the accommodating chamber 201 can enter the hollow chamber 410 through the liquid drain 411 and then be discharged through the liquid drain chamber 202 under the suction force of the drain pump. Meanwhile, the washing liquid in the storage chamber 201 may enter the drain chamber 202 through a gap between the outer wall surface of the main body 41 and the inner wall of the transition chamber 203. In the opened state, if the main body 41 does not completely exit the transition chamber 203, most of the washing liquid in the accommodating chamber 201 passes through the liquid outlet 411 and enters the liquid outlet chamber 202 through the hollow chamber 410, so as to increase the liquid outlet speed.

With continued reference to fig. 4 and 7, at least a portion of the wall surface of the movable member 4 facing the accommodating cavity 201 is a conical surface 44, and the flared end of the conical surface 44 is closer to the transition cavity 203 than the closed end thereof; the conical surface 44 is provided with a groove 440 which is recessed inwards along the radial direction; the density of the movable member 4 is smaller than that of the solution in the accommodating chamber 201, so that the movable member 4 can enter the groove 440 when the cup body 2 is filled with the washing liquid, and generate buoyancy to the main body 41 toward away from the transition chamber 203, so that the movable member can be kept in the open position by the buoyancy.

For example, the movable member 4 is made of foam material and can float on the solution in the accommodating chamber 201.

Optionally, in order to facilitate the installation and the removal of the movable member 4, please refer to fig. 2 to 4, 6, 9 and 10, the residual liquid treatment mechanism further includes a fixed seat 3 hermetically and detachably disposed on the inner wall of the transition chamber 203. The fixed seat 3 is provided with a mounting cavity 30 with two ends respectively communicated with the containing cavity 201 and the liquid discharging cavity 202, and the movable piece 4 is arranged on the transition cavity 203 by being slidably arranged in the mounting cavity 30; in the closed state, the sealing portion 42 on the movable member 4 seals the inlet end or the inner wall surface of the transition chamber 203 by sealing the inlet end or the inner wall surface of the installation chamber 30.

There are various ways of matching the fixing seat 3 with the transition cavity 203, for example, as shown in fig. 6 and 9, an annular protrusion 33 is protruding outwards on the outer peripheral wall of the fixing seat 3, and the annular protrusion 33 is in threaded connection with the transition cavity 203.

For the mounting chamber 30, the mounting chamber 30 has a flared structure from the drain chamber 202 toward the receiving chamber 201, and the above-mentioned annular projection 33 preferably corresponds to a flared portion of the flared structure.

At least one handle 31 which is convenient to operate is arranged on the end part of the fixing seat 3 facing the accommodating cavity 201. The fixing seat 3 mainly plays a role in conveniently installing the movable piece 4 in the cup body 2, and the installation process among the cup body 2, the fixing seat 3 and the movable piece 4 is as follows: the fixed seat 3 is installed and fixed in the cup body 2 by holding the handle 31, and then the movable piece 4 is inserted into the fixed seat 3, so the invention has the advantages of simple structure and convenient installation.

One of the inner wall surface of the fixed seat 3 and the outer wall surface of the movable member 4 is provided with a slide groove 45 extending in the sliding direction of the main body 41, and the other is provided with a protrusion 32 which is inserted into the slide groove 45 and protrudes outward.

In this embodiment, as shown in fig. 4 and 9, the main body 41 is provided with a step surface 412, the main body 41 is divided into an upper half and a lower half by the step surface 412, the liquid outlet 411 is located at the upper half of the main body 41, the lower half of the main body 41 is provided with a thread 413, the thread 413 is sleeved with a retainer ring 6, that is, the retainer ring 6 is in threaded fit with the thread 413, a chute 45 is defined between the retainer ring 6 and the step surface 412, as shown in fig. 10, a protrusion 32 is arranged on the inner wall surface of the fixing seat 3, the protrusion 32 slidably extends into the chute 45, and when the main body 41 slides relative to the fixing seat, the protrusion slides in the chute to play a guiding role on the sliding of the main body 41, and the thread of the retainer ring is arranged to facilitate the installation of the protrusion in the chute; the retainer ring can also be arranged on the main body part in other fixing modes so as to form the sliding groove. As a modified embodiment, in other embodiments, the step surface and the retainer ring may be provided on the inner wall surface of the fixed seat 3, and the protrusion formed on the movable element 4 may slide in the chute enclosed between the retainer ring and the step surface.

Alternatively, referring to fig. 4, 9 and 10, there may be various embodiments of the driving mechanism, for example, the driving mechanism is a telescopic cylinder, or a gear and rack engaged, where the rack is fixedly connected to the movable member, so as to drive the movable member to perform a reciprocating sliding motion.

As a preferable mode of the driving mechanism, the driving mechanism 5 comprises a permanent magnet piece 51 and an electromagnetic piece 52, one of the permanent magnet piece 51 and the electromagnetic piece 52 is arranged on the movable piece 4, and the other is arranged on the cup body 2; the electromagnetic member 52 is adapted to be electrically connected to an ac power source to generate repulsive and attractive forces to the permanent magnet member 51; in the open state, one of the repulsive force and the attractive force is used as the driving force, and correspondingly, in the closed state, the other of the repulsive force and the attractive force is used as the driving force.

For example, as shown in fig. 9, a permanent magnet 51 is provided on the main body 41 to generate a fixed magnetic field; the electromagnetic member 52 is arranged on the cup body 2 and is positioned in the transition cavity 203, and the permanent magnet member 51 is closer to the accommodating cavity 201 than the electromagnetic member 52. The electromagnetic member 52 may be a coil, or other electromagnet, that is connected to a power source.

When the switch is made from the closed state to the open state, the electromagnetic member 52 is supplied with a forward current to generate a first electromagnetic field, and the first electromagnetic field generates a repulsive force to the fixed magnetic field in the direction of the accommodating cavity 201, so that the movable member 4 is kept in the open state; conversely, when switching from the open state to the closed state, negative current is applied to the electromagnetic member 52 to generate a second electromagnetic field which generates a suction force toward the liquid discharge chamber 202 to the fixed magnetic field, so that the sealing portion 42 seals against the end face of the transition chamber 203 or the inlet end of the installation chamber 30 to maintain the closed state, and the magnetic fields of the first and second electromagnetic fields are opposite in direction.

As a modification of the position where the electromagnet 52 is provided, the electromagnet 52 is provided on the main body 41 and is located in the accommodation chamber 201, and the permanent magnet 51 is closer to the transition chamber 203 than the electromagnet 52. At this time, in the open state, the electromagnetic field generates a suction force to the fixed magnetic field; in the off state, the electromagnetic field generates a repulsive force against the fixed magnetic field.

In other embodiments, the driving force of the movable member 4 for switching between the open state and the closed state may also be provided by a cylinder or the like, and the cylinder provides the driving force as is well known to those skilled in the art, which is not described in detail herein.

Taking the dishwasher illustrated in fig. 1 to 10 as an example, a specific operation of the residual liquid treating mechanism will be described:

when the dish washer works normally, the washing cavity and the accommodating cavity of the cup body are filled with washing water, at the moment, the movable piece is in a closed state, and the sealing part 42 on the movable piece cuts off the accommodating cavity 201 and the liquid draining cavity 202; the electromagnetic member 52 is electrified forward to generate a magnetic field, a downward attractive force is generated on the permanent magnetic member 51, and the movable member is kept in a closed state by virtue of the downward attractive force generated on the permanent magnetic member 51 by the electromagnetic member 52 and the gravity of the movable member.

When water drainage is started, the electromagnetic piece 52 is electrified reversely, the magnetic field direction of the magnetic field generated by the electromagnetic piece 52 is changed, and upward repulsive force is generated on the permanent magnetic piece 51, so that the movable piece moves towards the direction away from the liquid drainage cavity, and the movable piece is in an open state; meanwhile, the solution in the accommodating cavity enters the groove 440 to generate buoyancy towards the main body 41 away from the transition cavity 203, the movable part is kept in an open state under the action of repulsive force and buoyancy, and drainage is performed under the suction force of the drainage pump, at this time, the movable part 4 depends on the magnetic force and buoyancy between the permanent magnetic part 51 and the electromagnetic part 52, so that the position of the movable part 4 is not changed due to the suction force caused by the operation of the drainage pump, and drainage is not influenced; when the water level is lower than the movable part 4, the movable part 4 is lowered along with the water level of the water flow, after the water flow in the cup body 2 is completely discharged, the movable part 4 has no buoyancy effect at the moment before the operation of the washing pump is finished, and the movable part 4 maintains an open state for a certain time to be closed again under the action of electromagnetic force, namely has a delayed closing function, so that the situation that part of the water flow cannot be discharged in time due to other reasons is avoided; the movable part 4 is lowered along with the water level of the water flow, after the water flow in the cup body 2 is completely discharged, no buoyancy is acted at this time, namely, after the movable part 4 is closed relative to the cup body 2 by means of gravity of the movable part 4, the magnetic property of the electromagnetic part 52 is changed to enable the magnetic pole of the upper end of the electromagnetic part 52 to be opposite to the magnetic pole of the lower end of the permanent magnetic part 51, the movable part 4 is further strengthened in a closed state, and the water with siphon backflow prevention is sealed in a water drainage waterway and cannot flow back into the washing cavity 10. Since the movable member 4 moves to be in a closed state after the solution in the washing chamber 10 is discharged, i.e., the accommodating chamber 201 and the drain chamber 202 are blocked, even when the anti-siphon structure sucks air without sucking the liquid in the drain chamber 202, the remaining solution is stopped in the drain chamber 202 without reversely flowing into the accommodating chamber 201 to enter the washing chamber 10, thereby ensuring that no liquid remains in the washing chamber 10, and further avoiding bacteria and odor from being generated in the washing chamber 10.

Example 2

The present embodiment provides a residual liquid handling mechanism which is different from the structure of the residual liquid handling mechanism provided in embodiment 1 in that:

the movable member 4 is not slidably provided in the transition chamber 203 but rotatably provided on an inlet end or an outlet end of the transition chamber 203 through a rotation shaft; by rotating or swinging the movable member 4, the movable member 4 is enabled to block the end face of the inlet end or the end face of the outlet end of the transition cavity 203, that is, the movable member 4 is equivalent to a sealing cover, so that the movable member 4 is switched between the open state and the closed state, and the solution in the liquid draining cavity 202 can be blocked from reversely flowing into the accommodating cavity 201 and further reversely flowing into the washing cavity 10.

Further, the movable member 4 includes a main body portion 41 and a sealing portion 42 provided on the main body portion 41, the sealing portion 42 being distributed facing the transition chamber 203. In the closed state, the body portion 41 is covered on the end face of the inlet end or the end face of the outlet end of the transition chamber 203, and the sealing portion 42 is sandwiched between the body portion 41 and the end face of the inlet end or the end face of the outlet end of the transition chamber 203 to achieve sealing of the transition chamber 203, thereby cutting off the accommodation chamber 201 from the liquid discharge chamber 202. In contrast, in the open state, the main body portion 41 and the sealing portion 42 are rotated so as to avoid the inlet end or the outlet end of the transition chamber 203 to communicate the accommodation chamber 201 with the drain chamber 202.

The present embodiment provides a drainage device, including an anti-siphon structure, a suction mechanism, and a residual liquid treatment mechanism according to any one of the embodiments of embodiment 1 or embodiment 2, wherein an inlet end of the anti-siphon structure is communicated with a drainage chamber 202 of the residual liquid treatment mechanism, and the suction mechanism is connected with an outlet end of the anti-siphon structure.

In the drain device of this embodiment, in view of the residual liquid treatment mechanism of the above embodiment, the residual solution is stopped in the drain chamber 202 and does not reversely flow into the accommodating chamber 201 to enter the washing chamber 10, so that no liquid remains in the washing chamber 10, and bacteria and odor are prevented from growing in the washing chamber 10.
