Description

  TECHNICAL FIELD The present invention belongs to the field of washing machines, and more particularly, to a faucet for a washing machine and a washing machine.

  There are many manufacturers in the current faucet market for washing machines, and the standard has not been set. Therefore, when connecting to the water supply pipe joint of the washing machine, contact / sealing failure occurs at these connection points, causing water leakage. Since the faucet for conventional washing machines is always open during use, the water supply pressure after stopping water is too large, and the connection between the water supply pipe and the water faucet is not enough. When the water is separated, or when an unintended breakage occurs at the connection point, the water supply pipe falls off and water is scattered around. In addition, depending on the faucet, the problem of water leakage may occur even if the fluororesin tape, that is, the tetrafluoroethylene tape is wound. In particular, water is wasted in the case of an automatic washing machine that does not require human monitoring. What is more serious about water leakage is that the entire floor of the house is flooded and the floors, furniture, walls, etc. are damaged.

  Patent Document 1 discloses a new type of faucet for a washing machine. The washing machine faucet includes a throttle valve having a secondary valve fixedly connected to an outlet end thereof. The secondary valve includes a housing. Both upper and lower ends of the housing are opened, and stepped hole-like running water paths called a first running water path and a second running water path are provided inside. The upper end of the housing is fixedly connected to and communicates with the outlet of the throttle valve. An axially movable valve element drive rod is fitted in the flowing water path so as to fit therein. A gap is held 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 element drive rod extends from the housing and is exposed to the outside. The valve element drive rod firmly receives the elastic force of the spring and abuts on 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 point between the first flowing water path and the second flowing water path, and the water flow is enabled. Become. However, the valve body driving rod of the water faucet in the washing machine is difficult to package because the lower end thereof is extended from the housing and 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 valve body drive rod that fits the internal water flow path must be replaced or the entire faucet must be replaced, which lacks versatility and increases costs.

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

Those skilled in the art can interpret the specific meanings of the above terms in the present invention depending on the specific situation.

  1 to 7, the present invention provides a water faucet for a washing machine. The water tap for a washing machine includes a main body 1 and a water discharge head 2 connected to the main body. A water flow path communicating with the main body is provided inside the water discharge head 2. Further, it further includes a closing member 9 and a push-up post 10 which are provided separately. The closing member 9 is provided inside the water flow path and engages with the water discharge port 202 of the water discharge head to block the water flow path. One end of the push-up column 10 extends from the outside into the inside of the water discharge head via the water discharge port 202 of the water discharge head, engages with the closing member 9 and pushes up the closing member 9 to open the water flow path.

  The main body is the main part of the faucet, is a skeleton for mounting other parts, and is also a fixing member for mounting the water discharge head.

  One end of the main body is a screw connection part, which can be inserted into a connection port of a water pipe that is already provided in a consumer's house. Moreover, the screw connection makes it possible to ensure a tight seal. There is a stopper at the base of the screw. As a first effect of this, it is possible to regulate the situation where the screw excessively enters the connection port of the water pipe that is provided in advance and the connection port is destroyed. The second effect is that the stopper just shields the connection portion after the screw is turned in and tightened, so that the overall appearance is improved.

  An end of the water discharge head on the side opposite to the connection with the main body is a water discharge port, and the water flow flows out through the water discharge port. The outer corner of the spout may have a rounded chamfer structure. By smoothing the surface as in the chamfered structure of FIG. 3, it is possible to prevent water leakage due to damage or damage to the rubber packing of the water supply pipe.

  The inner wall of the water discharge head contracts inward at the water discharge port portion to form a water discharge port. The closing member and the push-up column are provided separately. The closing member is provided in the water flow path, is disposed at the upper end of the water discharge port, and is installed so as to engage with the water discharge port of the water discharge head. A packing may be provided on the closing member. The closing member can block the water flow path when it comes into sealing contact with the water outlet. One end of the push-up column extends from the outside into the inside of the water discharge head via the water discharge port of the water discharge head, engages with the closing member, and pushes up the closing member to open the water flow path. The push-up post and the closing member may be detachably connected, or may be separately installed. These come into contact with each other and the blocking member is pushed up to open the water flow. With this arrangement, the closing member can be hidden inside the water discharge head, and the push-up column can be separately packaged. Therefore, the periphery of the faucet becomes smooth and there is no rod exposed to the outside, which facilitates packaging and transportation and avoids damage due to collision. Further, when the push-up pillar or the closing member is damaged, it is easy to replace the member separately.

  As shown in FIGS. 3 to 6, the push-up column 10 of this embodiment is provided in the water supply pipe joint 3 of the washing machine, and contacts and engages with the closing member 9 to push up the closing member 9.

  The closing member is provided in the water flow path of the water discharge head and is movable up and down along the water flow path. When the closing member comes into sealing contact with the water discharge port, the water flow is blocked by closing the water discharge port. 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 post may be injection-molded integrally with the water supply pipe joint, or may be a separate member fixedly attached to the water supply pipe joint when necessary. When the water supply pipe is connected to the water discharge head through 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 contacts the closing member to push up the closing member. This opens the water flow path. If it is installed in this way, not only will it be easier to pack and transport, it will not be damaged by collision, but the faucet and water pipe will be manufactured as a set, so the connection between the water faucet and the water pipe will be perfectly compatible. To do. Therefore, 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 post 10 is inserted from one end of the water discharge port of the water discharge head, contacts the positioning portion 903, and pushes up the closing member 9. The other end of the push-up column 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 column, and may be a groove or a protrusion, but may be positioned and contactable with the push-up column. The push-up pillar extends into the water discharge head from the outside and then contacts the closing member via the positioning portion. When the water supply pipe joint is engaged with the water discharge head, the push-up column pushes 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 flow enters the water supply pipe via the water discharge port.

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

  As a preferred method, one end of the push-up column engages with the positioning portion. When the positioning portion is a groove, one end of the push-up column is inserted into the groove to position the closing member. On the other hand, when the positioning portion is a protrusion, one end of the push-up column may be a groove that engages with the protrusion. As a result, since the push-up column can push up the closing member straightly, the inclination of the closing member is avoided, and the poor sealing at the time of returning the position to the water discharge port is prevented.

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

  The push-up post may have a columnar shape, a square shape, a cross shape, or the like, and the shape of the concave groove may correspond to the shape of the push-up post. In addition, 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. Accordingly, when the water supply pipe joint and the water faucet are quickly connected, the push-up post provided in the joint just enters the concave groove and can push up the closing member. Therefore, the push-up column easily pushes the closing member straightly, and the inclination of the closing member is avoided, so that the sealing failure at the time of returning the position to the water outlet is prevented.

  Further, the push-up pillar 10 includes a standing 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 standing column 1002 corresponds to the inner diameter of the positioning groove, and the channel groove 1003 is provided in the lower portion or stand of the standing column.

  The stand of the push-up pillar may be three stands provided at intervals. In this case, a large gap is provided between the adjacent stands to allow the water flow. Further, the upper ends of the three stands are integrally molded with the standing columns, and the lower ends or 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 channel or a water flow hole. In this case, vertical passage grooves may be provided in the standing columns to facilitate passage of the water flow.

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

  The push-up column has a detachable connection system, and is integrally connected to the closing member when a faucet is to be installed. When the water supply pipe and the faucet are connected, the other end of the push-up column comes into contact with the protrusion inside the water supply pipe for the washing machine, and the push-up column and the closing member are pushed up, so that the water flow is generated between the closing member and the spout. It is possible to pass through the gap. With this arrangement, the push-up columns can be separately packaged during packaging, so that the faucet area is smooth and there is no rod exposed to the outside. Therefore, packing and transportation are facilitated, and damage due to collision can be avoided. Further, when the push-up pillar or the closing member is damaged, it is easy to replace the member 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 that 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 column 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 contact, engagement contact, or the like. The other end of the push-up column is provided so as to be engaged with the water supply pipe for the washing machine, and when the water supply pipe and the water tap for the washing machine are connected to each other, the other end of the push-up column can come into contact with the annular projection of the water supply pipe joint.

  Further, the positioning portion is a positioning groove. A screw is cut on the inner wall of the positioning groove, and one end of the push-up column that is inserted into the water discharge port of the water discharge head is screwed to the positioning portion. 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 pillar and the faucet can be easily packed separately. Further, when mounted and used, one end of the push-up column that is 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 column comes into contact with the inside of the joint of the water supply pipe and pushes up the closing member to allow passage of the water flow.

  As shown in FIGS. 3 to 6, this embodiment further limits the first and second embodiments. A seal groove 901 is provided on a side wall of the closing member 9 at one end facing the water outlet 202 of the faucet. A packing 902 is fitted in the seal groove 901 so that the inner wall of the water outlet 202 of the faucet is engaged with the packing 902.

  The closure 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 water outlet. The inside of the seal groove is arcuate or semi-circular in order to fit an O-ring to enhance the sealing performance. Alternatively, other types of packing may be provided depending on the shape of the groove. The inner wall of the water outlet 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 water discharge port can be completely brought into close contact with the packing, and the hermeticity is greatly enhanced.

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

  Since the longitudinal outer guide wall is provided on the outer circumferential wall of the sealing groove in the closing member, 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 the adjacent guide grooves 904. The guide rib 905 is provided so as to be engaged with the inner wall of the water discharge head 2, and is used for guiding the position return of the closing member 9 and sealing the water discharge port 202 of the water discharge head.

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

  As shown in FIGS. 3 to 6, this embodiment further limits the first embodiment or the second embodiment. 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 position regulation through hole serves to position and guide the closing member. When the water supply pipe is not connected, the base end of the guide column in the closing member is located exactly in the position regulating through hole at the center of the stopper piece. When the water supply pipe is connected, the guide column of the closing member penetrates the position regulating through hole at the center of the stop piece. The position regulation through hole plays a role of regulating and guiding the position of the guiding column in the vertical direction, and prevents the loss of the sealing function due to the inclination of the closing member.

  As a further measure, the stopper is a stop piece. The outer circumference of the stopper is fixed to the water flow path. A position regulation through hole is provided in the center of the stopper piece, and a water flow hole for passing a water flow is provided between the position regulation through hole of the stopper piece and the outer periphery.

  Method 1: The position regulating through hole of the stopper piece is surrounded by an inner annular rib, and the outer periphery of the stopper piece is an outer annular rib. A connecting rib is provided between the inner annular rib and the outer annular rib of the stopper piece, and a water flow hole is formed between adjacent connecting ribs. The stopper has N connecting ribs. N ≧ 2, preferably 3. By forming the water flow holes between the connection 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.

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

  As shown in FIG. 7, this embodiment is another implementation method. On the side wall of the closing member 9, guide ribs 905 that protrude outward are provided at intervals. The circle surrounded by the guide ribs 905 engages the inner wall of the water flow path and defines the movement of the closure member 9.

  A 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. If the number of the guide ribs is N, then N ≧ 2, preferably 3. Further, preferably, the diameter of the circle surrounded by the guide rib corresponds to the inner diameter of the flow path inside the water discharge head. As a result, the roles of positioning and guiding 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 rib may be provided in a step shape and extend from one end of the closing member. The guide rib on the side wall plays a role of position regulation and guide. The guide rib extending from one end may be fixedly connected with a 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 so that the spring and the closing member can be positioned and fixed better.

  Further, a position regulation stand 203 is installed and formed in a step shape 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 as not to move too much downward. Further, an engagement slope 204 is provided on the inner wall of the water flow path below the position regulation stand. A packing 902 is fitted on one end of the closing member, and the engagement slope engages the packing and makes a sealing contact.

  The closure member engages the inner wall of the water flow path to control the water flow. Therefore, the inner wall of the water flow path that is in sealing contact with the closing member is provided so as to project inward, and forms a water discharge port that is smaller than the inner diameter of the water flow path.

  A seal groove is provided at one end of the closing member facing the water outlet, 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 thus fitting the packing, the slope is formed substantially, and the water flow is shut off by making close contact and sealing contact with the engaging slope of the inner wall of the water flow path.

  When the blocking member blocks the water flow, the packing fitted to one end of the blocking member and the engagement slope of the water flow path make sealing contact, and the position regulation stand above the engagement slope is below the guide rib of the closure member. The closing member is closely supported by the end face and is regulated so as not to move too much downward. Further, it is possible to prevent the packing from being excessively pressed and losing the sealing function when the water pressure is too large.

  This 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 through a water supply pipe joint. A closing member 9 is provided inside the water discharge port of the washing machine faucet, and one end of the push-up column is provided inside the water supply pipe joint.

  The water supply pipe joint includes a pipe joint 302 and a lock sleeve 301. The lock sleeve 301 can move up and down with respect to the pipe joint 302, and can return to the position and be locked by a self-lock spring 303. Further, the lock sleeve and the pipe joint are prevented from coming off by the position regulating ring. This will be specifically described below.

  The slidable lock sleeve 301 is pushed down, the spout of the faucet is inserted into the water supply pipe joint 3, and then the lock sleeve 301 is released. Then, the elastic force of the self-locking spring 303 causes the lock sleeve to move upward by the action of recovering the elastic force and return to the position. This causes the self-locking chamfer structure to gradually move inward while pressing the ball 305. As a result, when the ball is pushed into the water discharge head groove 201 and a clicking sound is produced, it means that the ball having the self-locking structure is fitted into the groove 201 of the water discharge head of the faucet. This prevents the water supply pipe structure from falling off. Moreover, since the spout and the joint are sealed by the annular seal 304, no leakage occurs between the spout head of the faucet and the water supply pipe joint.

  The lock sleeve for connecting the water discharge head of the water faucet is movable, and the N balls contained therein perform a locking action. When an external force is applied downward, the unlocking chamfer structure of the faucet presses the ball to gradually move it outward. As a result, the ball is pushed into the lock release groove and cannot fit into the water discharge head groove, so that the faucet connected to the pipe can be easily removed.

  The push-up column 10 is preliminarily mounted inside the water supply pipe joint of the present embodiment, and the flow channel 1003 is provided around the base of the push-up column.

  When the water supply pipe of this embodiment is connected to the washing machine faucet, the push-up post of the water supply pipe naturally pushes up the closing member to compress the spring. When the knob of the faucet is rotated 90 °, the water flow enters the water discharge head through the main body, and then enters the water supply pipe for the washing machine through the water discharge port of the water faucet. Can enter.

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

  Only when the water pipe for the washing machine and the water tap for the washing machine are connected, the water tap supplies water to the water pipe to form a water flow path. When the water pipe for the washing machine and the faucet for the washing machine 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, water does not flow out through the spout, so that the property of the consumer is highly protected.
