Description

The present invention belongs to the field of washing machines, and specifically relates to washing machine faucets and washing machines.

There are many manufacturers in the current washing machine faucet market, and standards have not been set. Therefore, when connecting to the water supply pipe joint of the washing machine, contact / sealing failure occurs at these connection points, and a problem of water leakage occurs. In conventional washing machine faucets, the faucet is always open during use, so the water supply pressure after the water is stopped is too high, or the connection between the water supply pipe and the faucet is not sufficient. If they are separated, or if an unintended tear occurs at the connection point, the water supply pipe will fall out and water will be scattered around. Further, depending on the faucet, the problem of water leakage may occur even if the fluororesin tape, that is, the tetrafluoroethylene tape is wrapped around the faucet. In particular, water is wasted in the case of an automatic washing machine that does not require human monitoring. In addition, more serious of water leakage is that the entire floor of the house is flooded and the flooring, furniture, walls, etc. are damaged.

Patent Document 1 discloses a new type of washing machine faucet. The washing machine faucet includes a throttle valve with a secondary valve fixedly connected to the outlet end. The secondary valve includes the housing. Both upper and lower ends of the housing are open, and a stepped hole-shaped water flow path called a first water flow path and a second water flow path is provided inside, respectively. The upper end of the housing is fixedly connected to and communicates with the outlet of the throttle valve. A valve body drive rod that can move in the axial direction is fitted in the water flow path. A gap is maintained between the valve body drive rod and the outlet of the throttle valve, and a spring is loaded in the gap. Further, the lower end of the valve body drive rod extends from the housing and is exposed to the outside. The valve body drive rod receives the elastic force of the spring and firmly abuts at the boundary between the first flowing water path and the second flowing water path to prevent the passage of the water flow. When the valve body drive rod moves upward and compresses the spring, a throttle slit is formed between the valve body drive rod and the boundary between the first flow water path and the second flow water path, allowing the water flow to pass through. Become. However, the valve body drive rod of the faucet in the washing machine is difficult to pack because the lower end extends from the housing and is exposed to the outside, is easily damaged by a collision, and is inferior in appearance. Furthermore, if the valve body drive rod is damaged, the entire valve body drive rod that matches the internal water flow path must be replaced, or the entire faucet must be replaced, resulting in lack of versatility and high cost.

In view of the above, the present invention is proposed.

The push-up column is provided separately and is attached to the joint of the water supply pipe in the washing machine. The push-up column may be injection-molded integrally with the water supply pipe joint, or may be fixedly attached to the water supply pipe joint as a separate member when necessary. When the water supply pipe is connected to the water discharge head via the water supply pipe joint, the push-up pillar in the water supply pipe joint extends from the water discharge port of the water discharge head into the inside of the water discharge head and comes into contact with the closing member to push up the closing member. As a result, the water flow path is opened. In this way, not only is it easier to pack and transport and avoid damage due to collisions, but the faucet and water supply pipe are manufactured as a set, so the connection between the faucet and the water supply pipe is perfectly compatible. To do. Therefore, the occurrence of an unexpected situation is avoided.

Further, the closing member 9 is provided with a positioning portion 903 that engages with the push-up column. The push-up pillar 10 is inserted from one end of the water discharge port of the water discharge head, comes into contact with the positioning portion 903, and pushes up the closing member 9. Further, the other end of the push-up pillar 10 is fixed inside the water supply pipe joint 3 of the washing machine.

The positioning portion of the closing member is a portion that comes into contact with the push-up pillar, and may have a concave groove or a protrusion, but it may be positioned and contact with the push-up pillar. After extending into the water discharge head from the outside, the push-up pillar comes into contact with the closing member via the positioning portion. Then, when the water supply pipe joint engages with the water discharge head, the push-up pillar pushes up the closing member upward, so that the closing member is separated from the water discharge port and a gap is formed. As a result, the water stream enters the water supply pipe via the spout.

Further, the positioning portion 903 is a concave groove. The concave groove is provided on the bottom surface of one end of the closing member 9 facing the water discharge port 202. When the water supply pipe joint 3 is connected to the water discharge head 2, the tip of the push-up pillar 10 is inserted into the concave groove to push up the closing member 9 and allow the water flow to pass through.

As a more preferable method, the inner diameter of the concave groove is set to correspond to the outer diameter of the push-up column fixed inside the water supply pipe joint.

The push-up pillar may be cylindrical, square, cross-shaped, or the like, and the shape of the concave groove may correspond to the shape of the push-up pillar. Moreover, the inner diameter of the concave groove is set so as to correspond to the outer diameter of the push-up column fixed inside the water supply pipe joint. As a result, when the water supply pipe joint and the faucet are quickly connected, the push-up pillar provided in the joint just enters the concave groove, and the closing member can be pushed up. Therefore, the push-up pillar easily pushes up the closing member straight, and the inclination of the closing member is avoided, so that a sealing failure at the time of returning to the water discharge port is prevented.

Further, the push-up pillar 10 includes an upright pillar 1002 and a stand 1001. The stand 1001 is fixedly connected to the inside of the water supply pipe joint 3. The outer diameter of the erection pillar 1002 corresponds to the inner diameter of the positioning groove, and the flow path groove 1003 is provided in the lower part of the erection pillar or the stand.

The stands of the push-up pillars may be three stands provided at intervals. In this case, a large gap is provided between the adjacent stands to allow the passage of water. Further, the upper ends of the three stands are integrally molded with the erection pillars, and the lower ends or the side walls of the three stands are integrally molded with the side walls of the water supply pipe joint. Alternatively, the lower ends of the three stands are fixedly attached to the annular boss inside the water supply pipe joint. Further, the stand may be an annular stand, and the annular stand may be provided with a flow path groove or a water flow hole. In this case, a vertical flow path groove may be provided in the vertical column so that the water flow can easily pass through.

One end of the push-up pillar 10 in this embodiment is inserted into the water discharge port 202 of the water discharge head 2 and is removably connected to the closing member 9.

The push-up pillar will be a removable connection method, and if you want to install a faucet, connect it to the closing member so that it is integrated. When the water supply pipe and the faucet are connected, the other end of the push-up pillar comes into contact with the protrusion inside the water supply pipe for the washing machine, and the push-up pillar and the closing member are pushed up so that the water flow is between the closing member and the spout. It becomes possible to pass through the gap of. If it is provided in this way, the push-up pillar can be packed separately at the time of packing, so that the circumference of the faucet becomes smooth and there is no rod exposed to the outside. Therefore, not only can it be easily packed and transported, but also damage due to a collision can be avoided. Further, when the push-up column or the closing member is damaged, the member can be easily replaced separately.

Further, the closing member 9 is provided with a positioning portion 903 that engages with the push-up column 10. One end of the push-up pillar, which is inserted into the water discharge port of the water discharge head, is detachably connected to the positioning portion. Further, the other end of the push-up pillar is provided so as to engage with the water supply pipe for the washing machine.

One end of the push-up column is detachably connected to the positioning portion of the closing member by, for example, screw connection, insertion, engagement, or the like. The other end of the push-up column is provided so as to engage with the water supply pipe for the washing machine, and can come into contact with the annular protrusion in the water supply pipe joint when the water supply pipe and the water faucet for the washing machine are connected.

Further, the other end of the push-up column comes into contact with the inside of the joint of the water supply pipe.

At the time of packing, the push-up column and the faucet can be easily packed separately. Further, when mounted and used, one end of the push-up pillar inserted into the water discharge port of the water discharge head is screwed to the positioning groove of the closing member. When the water supply pipe for the washing machine is engaged with the faucet, the other end of the push-up pillar comes into contact with the inside of the joint of the water supply pipe and pushes up the closing member to allow the water flow to pass through.

As shown in FIGS. 3 to 6, this embodiment further limits Example 1 and Example 2. A seal groove 901 is provided on the side wall of one end of the closing member 9 facing the water spout 202 of the faucet. A packing 902 is fitted in the seal groove 901, and the packing 902 is provided so as to engage with the inner wall of the spout 202 of the faucet.

The closing member may be a plug. A seal groove is provided on the side wall of one end of the closing member that comes into contact with the spout. The inside of the seal groove is arcuate or semicircular in order to fit an O-ring to enhance the sealability. Alternatively, other types of packing may be provided depending on the shape of the groove. The inner wall of the spout of the faucet and the packing are provided so as to engage with each other. Preferably, the inner wall of the spout of the faucet is provided with an arcuate surface that engages with the packing. According to this, the inner wall of the spout can be completely adhered to the packing, and the sealing property is greatly enhanced.

As a further measure, a flow guide groove 904 for passing a water flow is provided on the outer wall in the circumferential direction of the upper portion of the seal groove 901 in the closing member.

Since the outer wall in the circumferential direction of the upper part of the seal groove in the closing member is provided with a vertical guiding groove, the water flow can flow between the side wall of the closing member and the inner wall of the water discharge head via the guiding groove. Is. As a result, the water flow resistance due to the closing member is reduced as much as possible, so that the flow rate and the flow velocity do not decrease.

Preferably, the guide grooves 904 are provided at intervals along the water flow direction, and guide ribs 905 are formed between adjacent guide grooves 904. The guide rib 905 is provided so as to engage with the inner wall of the water discharge head 2, and is used to guide the position return of the closing member 9 and to seal the water discharge port 202 of the water discharge head.

Vertical guide ribs provided at intervals are further installed on the outer wall in the circumferential direction of the upper portion of the seal groove in the closing member, and the space between the adjacent guide ribs is a flow guide groove. The outer wall of the guide rib has an arc shape that engages with the inner wall of the water discharge head, and can play a role of position regulation and guidance while enabling smooth vertical movement of the closing member. Therefore, when the closing member is pushed up or the position of the closing member is returned, problems such as loss of the sealing function due to the inclination of the closing member can be prevented.

As shown in FIGS. 3 to 6, this embodiment further limits Example 1 or Example 2. An elastic member is connected to one end of the closing member 9 facing the main body 1, and the other end of the elastic member is in contact with a stopper at the lower end of the main body. The elastic member acts so that the closing member returns to its position and seals the water discharge port 202 of the water discharge head.

The elastic member of this embodiment is a spring 8, and the stopper is a stop piece 7. The stop piece is fixedly connected to the inside of the water discharge head. The fixed connection may be any method that can realize a fixed connection such as screw connection, engagement, adhesion, and tightening connection. In this embodiment, a tight fit connection is adopted. Since the central through hole 11 is provided in the center of the stop piece, water flow resistance can be effectively prevented and the flow rate and flow velocity in the pipeline are not reduced. An annular boss is provided at the lower end of the stop piece. The outer diameter of the annular boss adapts to the inner diameter of the spring, preferably slightly larger than the inner diameter of the spring so that one end of the spring is fixed.

The outer diameter of the spring is slightly smaller than the inner diameter of the water discharge head, and by freely moving along the inner wall of the water discharge head, it is possible to realize a vertical expansion and contraction movement. Moreover, since the position of the spring is restricted by the inner wall of the water discharge head, it is possible to prevent a situation in which the spring is curved in the vertical direction due to the expansion / contraction movement, the plug is biased, and the sealing function is lost.

A positioning rib 906 for fixing the spring is provided at one end of the closing member facing the main body.

A connecting rib is provided between the inner annular rib and the outer annular rib of the stop piece, and a water flow hole is formed between the adjacent connecting ribs. The stop piece is provided with N connecting ribs. N ≧ 2, preferably 3. By providing a water flow hole between the connecting ribs, the cross-sectional area of the water flow can be expanded as much as possible, so that the fluid resistance can be reduced as much as possible.

Plan 2: A position-regulating through hole is provided in the center of the stop piece, and a plurality of water flow holes are distributed in the main body of the stop piece between the position-regulation through hole and the outer circumference. As a result, the cross-sectional area of the water flow is expanded, so that the fluid resistance can be reduced as much as possible.

As shown in FIG. 7, this embodiment is another implementation plan. Guide ribs 905 projecting outward are provided on the side wall of the closing member 9 at intervals. The circle surrounded by the guide rib 905 engages with the inner wall of the water flow path and defines the movement of the closing member 9.

An guide rib that projects outward is provided on the side wall of the closing member, and the guide rib has three roles of positioning, guiding, and position regulation. Assuming that the number of the induction ribs is N, N ≧ 2, preferably 3. Also, preferably, the diameter of the circle surrounded by the guide ribs corresponds to the inner diameter of the flow path inside the water discharge head. As a result, the roles of positioning and guidance are realized, and the loss of the sealing function due to the inclination of the closing member during the vertical movement is effectively prevented.

The guide ribs may be provided in a stepped shape and may be extended from one end of the closing member. The guide ribs on the side wall serve as a position-regulating and guiding role. Further, the guide rib extending from one end may be fixedly connected to the spring as the positioning rib 906. Preferably, the diameter of the circle surrounded by the positioning ribs is slightly smaller than the outer diameter of the spring for better positioning and fixation of the spring and closing member.

Further, a position regulation stand 203 is installed and formed in a stepped manner on the inner wall of the water flow path. The position regulating stand 203 is closely supported by the lower end surface of the guide rib 905 of the closing member, and regulates the closing member so that it does not move excessively downward. Further, an engaging slope 204 is provided on the inner wall of the water flow path below the position regulation stand. A packing 902 is fitted at one end of the closing member, and the engaging slope engages with the packing and makes a sealing contact.

The closing member engages with the inner wall of the water flow path to control the water flow. Therefore, the inner wall of the water flow path that comes into close contact with the closing member is provided so as to project inward, and forms a spout smaller than the inner diameter of the water flow path.

A seal groove is provided at one end of the closing member facing the spout, and a packing is fitted in the seal groove. The diameter of the closing member above the packing is slightly larger than the diameter of the closing member below the packing. By fitting the packing in this way, a slope is substantially formed, and the water flow is blocked by making close contact and sealing contact with the engaging slope of the inner wall of the water flow path.

When the closing member blocks the water flow, the packing fitted at one end of the closing member and the engaging slope of the water flow path make a sealing contact, and the position regulating stand above the engaging slope is under the guiding rib of the closing member. It is closely attached to and supported by the end face, and regulates the closing member from moving excessively downward. Further, when the water pressure is too high, the packing is excessively pressed to prevent the sealing function from being lost.

The present embodiment provides a washing machine including a water supply pipe for a washing machine and a water supply pipe joint 3. The washing machine water supply pipe is attached to the washing machine water faucet via a water supply pipe joint. A closing member 9 is provided inside the spout of the washing machine faucet, and one end of the push-up pillar is provided inside the water supply pipe joint.

The water supply pipe fitting includes a pipe fitting 302 and a lock sleeve 301. The lock sleeve 301 can move up and down with respect to the pipe joint 302, and can be locked by returning to the position by the self-lock spring 303. In addition, the lock sleeve and the pipe joint are prevented from falling off by the position regulating ring. The details will be described below.

The slidable lock sleeve 301 is pressed, the spout of the faucet is inserted into the water supply pipe joint 3, and then the lock sleeve 301 is released. Then, due to the elastic force of the self-locking spring 303, the lock sleeve moves upward by the action of recovering the elastic force and returns to the position. As a result, the self-locking chamfer structure gradually moves inward while pressing the ball 305. As a result, when the ball is pushed into the concave groove 201 of the water discharge head and a clicking sound is heard, it means that the ball having a self-locking structure is fitted into the concave groove 201 of the water discharge head of the faucet. As a result, the water supply pipe structure does not come off. Moreover, since the water spout and the joint are sealed by the annular seal 304, leakage does not occur between the water discharge head of the faucet and the water supply pipe joint.

The lock sleeve that connects the spouting head of the faucet is movable, and the N balls inside it act as a lock. When an external force is applied downward, the unlocking chamfer structure of the faucet presses the ball and gradually moves it outward. As a result, the ball is pushed into the unlocking recess and cannot be fitted into the water discharge head recess, so that the faucet connected to the pipe can be easily removed.

A push-up pillar 10 is preliminarily mounted inside the water supply pipe joint of this embodiment, and a flow path groove 1003 is provided around the base of the push-up pillar.

When the water supply pipe of this embodiment is connected to the washing machine faucet, the push-up pillar of the water supply pipe naturally pushes up the closing member and compresses the spring. When the knob of the faucet is rotated by 90 °, the water flow enters the water discharge head via the main body, and then enters the water supply pipe for the washing machine through the water discharge port of the faucet, so that the water flow enters the washing machine. It becomes possible to enter.

The push-up column is preferably injection-molded integrally with the water supply pipe joint. However, the push-up column may be a single member or may be fixed to a faucet joint.

Only when the water supply pipe for the washing machine and the faucet for the washing machine are connected, the faucet supplies water to the water supply pipe and forms a water flow path. If the washing machine water supply pipe and the washing machine faucet are not connected or come off, the closing member inside the faucet seals the spout of the faucet. Even if the valve core opens inside the faucet, the water will not flow out of the spout, so the consumer's property is extremely highly guaranteed.

The above is merely a preferred embodiment of the present invention and does not limit the present invention to any form. Although the present invention has been disclosed as described above by preferred embodiments, it is not intended to limit the present invention, and the technical contents presented above by those skilled in the art will be used as long as the technical plan of the present invention is not deviated.
