[ detailed description ] embodiments

The present invention provides a backstop device of a clothes treatment apparatus, comprising: a main channel for fluid flow; and a backstop disposed within said primary passage, said backstop having an open state permitting passage of forward flow fluid within said primary passage and a closed state preventing passage of reverse flow fluid within said primary passage; and the bypass channel is communicated with the main channel and is used for dredging counter-flow fluid in the main channel when the backstop is in a closed state. When the reverse flow fluid enters the main channel, the check piece is in a closed state, the reverse flow fluid is prevented from passing through the check piece, and part of the reverse flow fluid blocked by the check piece is drained outwards from the bypass channel, so that the burden of the check piece is relieved, and the risk that the check piece is penetrated by the reverse flow fluid and even fails is reduced.

The technical solutions of the embodiments of the present invention are explained and illustrated below with reference to the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

Referring to fig. 1 and 2, a backstop of a laundry treating apparatus proposed in one embodiment of the present invention includes: a main channel 100 for fluid flow; and, a backstop disposed within main passage 100, the backstop having an open state permitting passage of forward flow fluid within main passage 100 and a closed state preventing passage of reverse flow fluid within main passage 100; and a bypass passage 300 communicating with the main passage 100 for channeling a reverse flow of fluid in the main passage 100 when the check is in a closed state.

In this embodiment, the backstop includes a baffle 200 adapted to the cross section of the main channel 100 to substantially block the reverse flow, for example, if the cross section of the main channel 100 is circular, the baffle 200 is also designed to be circular, but there is a clearance fit between the two, and the baffle 200 is opened and closed without interference from the main channel 100. The baffle 200 is configured to be normally closed, i.e., to be kept closed without external force, and to be rotated and opened in the forward flow direction by the forward flow fluid force, so that the backstop is simple in structure and effectively performs a backstop function at low cost by a passive opening manner without mechanical additional power.

As a preferable scheme: the upper end of the baffle 200 is rotatably connected with the main channel 100, for example, the upper end of the baffle 200 is provided with a rotating shaft 210, the inner wall of the main channel 100 is provided with a clamping groove, the rotating shaft 210 is rotatably limited in the clamping groove, because the upper end of the baffle 200 is rotatably connected with the main channel 100, the gravity center of the whole baffle 200 is lower than the rotating connection part of the baffle 200, the baffle 200 is kept in a free falling state by gravity, and the counter-flow fluid is blocked (as shown in fig. 1); the force exerted by the forward flow on the baffle 200 is greater than the weight of the baffle 200, allowing the forward flow to push the baffle 200 in a forward direction (as shown in fig. 2), such as by increasing the airflow velocity and flow with the fan power, thereby ensuring that the thrust of the airflow pushes the baffle 200 open.

The reverse flow fluid generated in the laundry treating apparatus is mainly washing fluid or bubbles, and is a reverse flow, and the acting force generated by the reverse flow fluid is small, and the baffle 200 cannot be pushed away in the reverse flow direction under normal conditions, but when a large flow of the reverse flow fluid or the laundry treating apparatus vibrates, the baffle 200 is not easily maintained in the closed state, and therefore, the baffle 200 is limited to be opened in the reverse flow direction in the main passage 100, so that the structural stability of the check is improved, and the check is prevented from being pushed away in the reverse direction by the reverse flow fluid to cause the check failure. The following are exemplary: a blocking part 130 for stopping the backstop in the reverse flow direction is provided on the inner wall of the main passage 100, and the lower end of the baffle 200 abuts against the blocking part 130 under the condition that the baffle 200 is kept in a free falling state by gravity, so that the reverse fluid cannot push the baffle 200 away in the reverse flow direction due to the blocking of the blocking part 130; in specific implementation, the blocking portion 130 may be a step integrally formed on the inner wall of the main channel 100, or may be a stopper independently installed on the inner wall of the main channel 100.

It can be understood that: the pivotal connection of the flapper 200 is not limited to the upper end of the flapper 200, and it is theoretically possible to keep the flapper 200 closed by gravity as long as it is ensured that the center of gravity of the flapper 200 is lower than the pivotal connection of the flapper 200 when the flapper 200 is pivotally connected to the inner wall of the main passage 100, and therefore, in other embodiments, the pivotal connection of the main passage 100 to the middle of the flapper 200 or a portion above the middle of the flapper 200 can be achieved.

With continued reference to fig. 1 and 2, the two ends of the main channel 100 are respectively provided with the inflow port 110 and the outflow port 120, such that the forward flow fluid flows from the inflow port 110 to the outflow port 120 in the main channel 100, and the reverse flow fluid flows from the outflow port 120 to the inflow port 110 in the main channel 100, in this embodiment, the bypass channel 300 is connected to the main channel 100 between the backstop (the baffle 200) and the outflow port 120, and is as close to the backstop as possible when the structure allows, such that a portion of the reverse flow fluid blocked by the backstop can be more effectively diverted from the bypass channel 300 to the outside rapidly, thereby reducing the burden of the backstop and reducing the risk of the backstop being penetrated by the reverse flow fluid and even failing.

In one embodiment of the present invention, a backstop device according to the above embodiment: the check closes the bypass passage 300 when the check is in an open state, and closes the bypass passage 300 when the forward flow fluid flows through the main passage 100, thereby preventing the forward flow fluid from being lost from the bypass passage 300 to cause waste. Referring to fig. 2, in the above embodiment, the bypass channel 300 has a bypass opening 310 communicating with the main channel 100, a plug 220 is disposed at a side of the baffle 200 facing the bypass opening 310, and when the baffle 200 is opened by the forward flow fluid, the plug 220 blocks the bypass opening 310, thereby preventing the forward flow fluid from flowing out of the bypass channel 300 and causing waste.

In an embodiment of the present invention, based on the backstop device described in the above embodiment, another scheme for limiting the opening of the backstop in the reverse flow direction is proposed: the backstop is provided with a first magnet, a second magnet is arranged on the main channel corresponding to the backstop in a closed state, and the first magnet and the second magnet are mutually attracted and used for limiting the backstop to be opened in a reverse flow direction. Taking the foregoing embodiment as an example: set up first magnet at the lower extreme of baffle, the baffle that corresponds the closure state on the inner wall of main entrance sets up the second magnet, under the baffle closure state, first magnet and second magnet attract each other, can restrict the baffle and open to the direction of flow against the current to can prevent the baffle swing back and forth, the stability of baffle closure state is good, but the effort that down flow fluid applyed on the baffle is greater than the magnetic attraction between first magnet and second magnet, ensures that the baffle can be pushed open by down flow fluid.

In one embodiment of the present invention, a backstop device according to the above embodiment: the backstop further comprises an elastic component, the baffle is kept in a closed state by the elastic force exerted by the elastic component, namely the baffle can be reset by the elastic force exerted by the elastic component after being opened, and the embodiment is taken as an example: the elastic component is a torsion spring which is arranged on a rotating shaft at the upper end of the baffle and keeps a pre-tightening state, and the acting force of the downstream fluid on the baffle is greater than the elastic acting force of the torsion spring, so that the baffle can be pushed away by the downstream fluid; under the action of no other external force, the baffle plate is reset to a closed state and kept under the action of the elastic acting force of the torsion spring and the self gravity.

In other embodiments, the baffle is an elastic plate, such as a silicone baffle, a rubber baffle, etc., and the baffle constitutes an elastic member and is connected to the inner wall of the main channel by the elastic member, such as: the baffle comprises a circular body part and a connecting part which extends outwards from the body part, the connecting part is an elastic component, the body part is connected to the inner wall of the main channel through the connecting part, the body part plays a role in blocking countercurrent, and the connecting part provides bending elasticity for resetting the opened body part.
