Description

Sink hand spray draw-out return interference prevention device}

The present invention relates to a pull-out hand spray pull-out and return interference prevention device for a sink, and more particularly, a location pulled out by frictional interference with a hot and cold water pipe during the pull-out and return process of the pull-out hand spray, which is a faucet installed in the kitchen sink. The present invention relates to a pull-out type hand spray pull-out return interference prevention device for a sink capable of preventing frictional interference with a hot and cold water pipe so as to solve the problem of not being returned again from or not being easily pulled out in a restored state.

In general, a fixed type faucet or a pull-out type faucet is used in a home sink. Here, the fixed type faucet has a faucet body, a bellows type or a fixed type supply pipe is coupled to the upper end of the faucet body, and a hand spray head is formed at the tip of the supply pipe, and the withdrawable faucet is shown in FIGS. As described above, a tubular holder is configured as a faucet body, and a pull-out hand spray faucet is applied and used so that the tubular holder is taken out from the tubular holder to a specific length and used by a user. Here, the pull-out hand spray faucet is coupled to the tubular holder formed as the faucet body and is located inside the hand spray head and the tubular holder exposed to the outside. The mixing connection hose that receives the mixed supply is connected.

Here, the mixed connection hose is usually connected in a length corresponding to the length at which the hand spray can be drawn out, and a weight (weight) is installed on the mixed connection hose as a device for automatically returning the drawn mixed connection hose separately. Therefore, the mixing connection hose drawn out by the weight of the weight is configured to automatically return, and the mixing connection hose is always pulled down by the weight of the weight inside the tubular holder by the weight, so that the hand spray head exposed to the outside is It is kept to be stably stored in the tubular holder.

The mixing connection hose of such a hand spray is configured to mix and discharge cold and hot water, and is configured to receive a mixed supply by being combined with each of the cold and hot water connection hoses in the tubular holder. Therefore, a mixed connection hose, a cold water connection hose, and a hot water connection hose are built into the tubular holder and are combined.

As described above, the tubular holder has a mixed connection hose, a cold and hot water connection hose, and the mixed connection hose extends longer from the inside of the tubular holder to the inside of the sink or the object where the faucet is installed. When pulled from the tubular holder, the mixing connection hose is drawn out along the tubular holder, and when the hand spray head is moved to the position where the hand spray head is inserted into the top of the tubular holder, the mixing connection hose is pulled from the inside of the tubular holder to the inside of the sink or object by weight. As it loses, it returns to its original state.

As described above, the withdrawal hand spray is widely used in most household sinks or bathrooms because the hand spray can be withdrawn to a desired location as needed.

However, the withdrawal hand spray has a problem in that it is not easy to withdraw or return smoothly as the cold and hot water connection hoses are installed in the tubular holder.

In other words, in the process of withdrawing the mixed connection hose, even if friction or interference with the cold or hot water connection hose occurs as it is pulled by external force, it is easily withdrawn, but when it is returned by weight, the mixed connection hose is inside the tubular holder. , Due to friction and interference due to contact with the hot water connection hose, the hand spray head cannot be stably held on the top of the tubular holder, and the hand spray head is combined in a partially exposed form of the mixing connection hose, so that the hand spray head is coupled to flow to an unstable position. The hand spray head rotates from the tubular holder or flows by water pressure when water is used, causing water to splash.

Moreover, the mixed connection hose applied to the pull-out hand spray has a clean appearance and uses a lot of stainless steel corrugated pipes for durability due to the nature of being pulled out and exposed to the outside. Interference is taking place more easily, and it is more difficult to return to the tubular holder after withdrawal.

Further, in order to solve this problem, there have been attempts to solve this by increasing the weight of the weight, but when the weight of the weight increases, there is a problem that the user must exert excessive force in the process of drawing out the hand spray head, resulting in inconvenience in use. As a result, great effectiveness was not obtained.

In addition, interference between the mixed connection hose and the cold and hot water connection hose has a problem in that durability decreases due to frequent friction or jamming in the process of pulling out and returning the mixed connection hose.

Therefore, there is a need for a pull-out hand spray faucet capable of smooth withdrawal of the mixed connection hose of the hand spray that is pulled out and returned, and that can be returned without interference with the cold and hot water connection hoses.

As shown in FIGS. 1 and 2, a conventional withdrawal hand spray provides cold and hot water connection hoses 1 and 2 connected to the building's cold and hot water supply pipes, and cold and hot water from the cold and hot water connection hoses. A hand spray head (3) that is supplied and is connected to the mixing supply hose (3) to which the weight (4) is combined and discharged by mixing cold and hot water, or by selecting and discharging cold or hot water ( 5) And, a tubular holder 6 is formed in which the rear end of the hand spray head 5 is detachably fitted and communicated to be taken out, and cold and hot water are selectively discharged to the hand spray head 5 at the front. The faucet body 8 is formed with a control lever 7 that adjusts to be mixed or discharged, and the faucet body 8 is integrally formed at the bottom of the faucet body 8, and is inserted into a coupling hole formed on the upper surface of the sink bowl of the sink to the inside of the sink. A screw is formed on the outer periphery so that the faucet body is fixed to the sink by bolting on the lower surface, the cold and hot water connection hoses 1 and 2 and the mixing supply hose 3 are built-in, and the mixing supply hose 3 is It is withdrawn according to the withdrawal operation of the hand spray head 5, and is formed of a tubular fastening portion 9 provided to communicate with the tubular holder 6 so as to move while being returned by the weight 4.

Such a conventional sink withdrawal hand spray faucet is installed on the top of the sink bowl of the sink, and the withdrawn mixed supply hose 3 and the cold and hot water connection hose are located inside the sink in a concealed state so as not to be exposed to the outside. Here, the cold/hot water connection hose is connected to the cold/hot water supply pipe of the building and extends, and the mixed supply hose is connected to the cold/hot water connection hose connected to the cold/hot water supply pipe, and both the mixed supply hose and the cold/hot water connection hose are connected in a tubular shape. The hoses are concentrated in the inner space of the tubular connection part because it is built in as a part, and as a result, the mixed supply hose drawn out due to the narrow space is drawn out due to excessive external force due to the friction caused by interference or contact with the cold and hot water connection lakes. Therefore, there is a difficulty that must be pulled. In addition, even in the action of the weight to return it, there is a problem in that the return is restricted due to interference between each hose due to the narrow space in the tubular fastener or friction due to contact, or a problem of maintaining the withdrawn state as it is, through the present invention. This was resolved.

The pull-out hand spray pull-out return interference prevention device 100 according to the present invention is pulled out by friction due to interference and contact between the mixing supply hose and the cold and hot water connection hose when the aforementioned mixing supply hose is pulled out and returned. To solve the problem of limiting the return, as shown in Figs. 3 and 5, the mixed supply hose 3 is provided by the cold and hot water connection hoses 1 and 2 built in the tubular fastening unit 9 According to the withdrawal operation of the hand spray head (5), it is smoothly drawn out without contact or interference during the withdrawal process, and when returned by the weight (4), it does not come into contact with or interfere with the cold and hot water connection hoses (1, 2). A pull-out return interference prevention hole 100 provided with an interference prevention hole 104 penetrating up and down so that the mixing supply hose 3 is moved to one side of the inner circumference of the tubular fastening part 9 so as to be smoothly returned. Is formed.

Here, the withdrawal return interference prevention device 100 is as shown in FIG. 5, the withdrawal return interference prevention device 100 is a cold, hot water connection hose (1, 2) built in the tubular fastener (9) Doedoe coupled so as not to be forcibly fitted to the lower end of the tubular fastening portion, as shown in Figure 4, consisting of a main body housing 102, an interference prevention through hole 104, a guide taper 106.

The body housing 102 has a cylindrical shape so that the hand spray faucet is inserted into a coupling hole formed in the sink bowl of the sink so that the hand spray faucet is fixed to the outer edge of the sink bowl, and corresponds to the inner vertical height of the tubular fastening portion 9 located under the sink. Is formed. Here, when the length of the main housing 102 is formed to be shorter than the upper and lower heights of the tubular fastener, the cold and hot water connection hoses 1 and 2 are mixed in the tubular fastener according to the trunk line or contact with the supply hose 3 A section where friction occurs, the user still has to pull out the hand spray head through excessive force in the process of withdrawing the hand spray head, and even in the process of being restored by the weight, the return is smoothly caused by interference and friction caused by contact. It doesn't work.

Moreover, when the main housing 102 is short and a section that interferes with and rubs against the cold and hot water connection hoses 1 and 2 occurs, the mixed supply hose 3 is jammed at the upper end of the main housing. In the withdrawal process, the mixing supply hose 3 may be smoothly withdrawn, but in the return process, as described above, the mixed supply hose is jammed at the upper end of the main body housing, which makes it impossible to return itself. There is a problem to be done.

On the other hand, when the length of the main body housing 102 is formed to be long and protrudes outward from the lower end of the tubular fastening part 9, it is exposed to protrude inside the sink and is not seen in appearance. There will be a limitation of the problem. Therefore, as described above, the main body housing 102 is preferably formed to be the same as the inner upper and lower heights of the tubular fastening portion 9 or to be able to adjust its size within a structural error range.

The interference prevention through hole 104 prevents interference and contact with the cold and hot water connection hoses 1 and 2, which are located together in the tube fastening part 9, in the process of pulling out and returning the mixed supply hose 3. In the process of pulling out the hand spray head by preventing the friction caused by the user, the pulling out of the mixed supply hose (3) is guided so that it can be pulled out smoothly without pulling it with a special force, and the user can also use the hand spray head in the process of returning by weight. It is configured to be smoothly moved and returned in the process of fitting the tube holder. As shown in Figs. 5 to 7, the mixing supply hose 3 is penetrated through the center of the main body housing 102 so that the vertical movement is smoothly performed. It is prepared to be done.

Here, the interference-preventing through hole 104 is preferably formed to have a diameter larger than the diameter of the mixed supply hose 3, and after being inserted and coupled into the tubular fastening section 9, as shown in FIG. 7, the tubular fastening section It is preferable that the inner space of (9) is formed in a size capable of securing a space in which the cold and hot water connection hoses 1 and 2 can be located.

The guide taper 106, as shown in Figs. 4 and 6, guides the mixing supply hose 3 to be smoothly moved along the above-described interference prevention through hole 104 in the withdrawal and return process, the The interference prevention through hole 104 is configured to guide the upper and lower inner circumferences of the mixed supply hose 3 so as to be able to move smoothly during the withdrawal and return.

As shown in FIG. 4, the guide taper 106 has an upper side of the main body housing 102 in the shape of an upper side of the upper side of the body housing 102 as an interference-preventing through-hole side, and When the mixed supply hose 3 is withdrawn in the process of withdrawing the spray head, it does not get caught in the end of the lower end of the main body housing 102 in the process of moving upward to the interference-preventing through hole 104, and smoothly prevents interference through the through hole. The mixture supply hose 3 is not caught at the end of the upper end even when it enters and moves to 104, and when it is returned again by the weight, it smoothly enters downward into the interference-preventing hole 104 and returns.

Moreover, the guide taper 106 is a mixed supply hose ( 3) is provided so as not to be caught on the upper end of the main body housing, and is directly guided to the interference-preventing through hole 104 to move, so that the mixing supply hose is pulled out and returned smoothly.

On the other hand, the tubular fastening by increasing the contact area and frictional force with the cold and hot water connection hoses (1, 2) built in the tubular fastening part (9) on the outer periphery of the main body housing (102) of the withdrawal and return interference prevention device (100) As shown in Fig. 8 so as to prevent separation from the portion 9, a plurality of irregularities 108 are formed. That is, the withdrawal and return interference preventing hole 100 is a cylindrical shape, with an interference preventing hole formed therein, and a main body housing 102 configured with a guide taper at the upper and lower ends of the main body housing 102 fitted into the tubular fastening part 9, but cold and hot water By forcing the connection hose and the withdrawal and return interference preventing device 100 to be forcibly fitted with respect to the inner diameter of the tubular fastening part 9, it is possible to prevent and combine the withdrawal and return interference prevention device from the tubular fastening part. By forming a plurality of irregularities 108 in the main body housing 102 as a configuration for reinforcement, the cold and hot water connection hose and the withdrawal return interference prevention device 100 are forcibly fitted to correspond to the inner diameter of the tubular fastening part 9 At the time, it is possible to reinforce the separation prevention of the return interference preventing device 100 withdrawn from the tubular fastening part 9 by increasing the contact area and increasing the frictional force.

Here, the unevenness 108 is fitted to prevent scratches or damage to the outer edge of the cold and hot water connection hose when it is fitted with the tubular fastening part 9, and is formed as a wedge-shaped unevenness to further improve separation prevention. It is desirable.

On the other hand, as shown in Figs. 9 and 10, it is also preferable to configure a ring-shaped wedge fastening portion 200 toward the outer periphery of the lower body housing 102. Here, as the ring-shaped wedge fastening part 200 is wedge-coupled to the lower end of the tubular fastening part 9, it is possible to more stably prevent separation of the withdrawal and return interference preventing device 100. Accordingly, the body housing 102 is coupled to the wedge fastening part 200 so as to be located at one side of the inner circumference from the center of the wedge fastening part, that is, connected to the tubular fastening part 9 by combining it at an eccentric position. It is configured to form a space in which the hose will be located.

Such a wedge fastening part 200 is formed larger than the inner circumferential diameter of the tubular fastening part 9, and a plurality of wedge protrusions 202 are formed on the outer circumference of the tubular fastening part 9 to form a wedge on the inner circumference of the tubular fastening part 9 It is formed in a ring shape to be combined. In addition, as described above, the wedge fastening part 200 is built in the tubular fastening part 9 of the cold and hot water connection hoses 1 and 2 from the center of the ring shape to one side so that the main body is not interfered with. The central axis of the housing is integrally formed at a position eccentric from the central axis of the tubular fastening portion 9.

In addition, the cylindrical body housing 102 integrally formed with the wedge fastening part prevents cylindrical interference so that the withdrawal and return of the mixing connection hose 3 is guided within the tubular fastening part 9 as described above. A through hole 104 is formed, and a guide taper 106 is formed in the inner periphery of the upper and lower ends of the interference-preventing through hole 104.

First, as shown in FIGS. 3 and 5, the tubular fastening portion 9 integrally formed with the faucet body 8 is fitted into the coupling hole formed on the outer edge of the sink bowl of the sink, and the outer portion of the tubular fastening portion 9 It is screwed to the peripheral thread portion with a nut so that the faucet body 8 is fixed to the top of the outer edge of the sink. Thereafter, the cold and hot water connection hoses (1, 2) are respectively coupled to the cold and hot water supply pipes of the building, and the cold and hot water connection hoses (1, 2) are connected by an adjustment lever (7) formed in front of the faucet body (8). After mixing or selectively supplying cold or hot water supplied through the cold and hot water, the cold and hot water is supplied from the cold and hot water connection hose, and a mixed supply hose (3) in which a weight 4 is coupled to one side. ) And connect.

Next, the front end of the mixing supply hose 3 is passed through the lower portion of the tubular fastening portion 9 in the order of the faucet body-tubular holder, and then pipe-coupled with the rear end of the hand spray head 5, and then, the hand spray head ( 5) As the rear end is fitted into the tubular holder, the mixing supply hose 3 is configured to move and return to the inside of the sink by the weight of the weight coupled to the mixing supply hose 3.

In this way, after installing the hand spray faucet on the sink, the front end of the cold and hot water connection hose is coupled so that it is connected to the control lever side, so the front end of the cold and hot water connection hose is located inside the tubular joint (9). In the inner space of the fastening section 9, the mixing supply hose 3 is configured to move up and down in the tubular fastening section 9 through the remaining space where the hot and cold connection hoses are located, but the hand spray head moves upward. This is the case when the user pulls out after being separated from the tubular holder, and the downward movement is made in the process of returning to the original state by the weight by the weight while the hand spray head is recombined to the tubular holder.

According to the installation of such a faucet, the mixing supply hose 3 is difficult to withdraw and return due to friction due to interference and contact with the cold and hot water connection hoses 1 and 2 in the tubular joint 9 To be solved through the withdrawal return trunk line prevention device 100, looks at the operation relationship through Examples 1 and 2.

<Example 1>

As shown in FIGS. 3 to 7, the cylindrical pull-out and return interference prevention device 100 without the wedge fastening part 200 is first connected to the hand spray head 5 and the mixing supply hose 3. The mixing supply hose (3) is movably coupled along the outer edge of the mixing supply hose (3), and the mixing supply hose (3) is passed through the interference prevention through hole (104) formed through the center of the main body housing (102) of the withdrawal and return interference prevention hole (100). Combine. At this time, it is preferable to form the diameter of the interference prevention through hole 104 larger than the outer circumferential diameter of the mixing supply hose (3). In addition, the diameter of the outer periphery of the main body housing 102 is the remaining space in which the cold and hot water connection hoses 1 and 2 are located in the inner diameter of the tubular fastening part 9, and the main housing 102 is forcibly fitted and fixed. It is desirable to form the diameter as possible.

That is, when the outer diameter of the main body housing 102 is smaller than the size of the remaining space in which the cold and hot water connection hoses 1 and 2 are located in the inner diameter of the tubular fastening part 9, the main housing 102 is Since it is easily separated, it cannot play the role of smoothing the withdrawal and return due to friction due to interference and contact between the cold and hot water connection hose and the mixed supply hose.If the outer diameter is larger than the size of the space, the main body housing itself is connected in a tubular shape. (9) Economical that it is impossible to combine with the inner diameter, or that cold and hot water connection hoses are pressurized, resulting in poor supply of cold or hot water due to pipe deformation of the cold and hot water connection hoses, or damage to the cold and hot water connection hoses and re-installation. Loss can occur.

As described above, as the withdrawal and return interference preventing device 100 according to the present invention is forcibly fitted to the tubular fastening part 9, the mixed supply hose 3 has a special force when the user pulls out the hand spray head 5 When the hand spray head is separated from the tubular holder without the need to provide a mixture, the mixing supply hose 3 prevents interference formed on the main body housing 102 of the withdrawal return interference prevention device 100 by the distance the hand spray head is separated from the tubular holder. It moves upward along the through hole 104, and there is no friction due to interference or contact with the cold or hot water connection hose during the upward movement process, so it is smoothly withdrawn.

Thereafter, after the user finishes using the hand spray head 5, when the hand spray head 5 is inserted into the tubular holder again, it is returned to its original state by the weight of the weight coupled to the mixing supply hose 3. At this time, the mixed supply hose 3 can be quickly returned by moving downwards without interference or friction from the cold and hot water connection hoses again through the interference prevention hole 106 as much as the drawn length, and according to the original state return, the hand spray head This prevents the hand spray head from flowing or sagging, which can occur when the hand spray head is not fully returned to the mixing supply hose and partially remains pulled out as it is coupled to the tubular holder in the correct position. It is done.

In other words, conventionally, due to the problem that the mixing supply hose 3 is not completely returned, the hand spray head is not fully coupled to the tubular holder, so the hand spray head simply spans the tubular holder. It is a problem that looks unsightly due to poor coupling of the spray head, and it remains in a wrong position rather than the normal position of the head due to poor coupling of the hand spray head. Although there was a problem of being discharged from the outside of the sink bowl or randomly, when the mixing supply hose is completely returned, the hand spray head is accurately coupled to the tubular holder to solve the above problem.

On the other hand, the length of the main housing 100 is formed in a size corresponding to the inner depth of the tubular fastening portion 9, that is, the upper and lower heights, and the length is short, resulting in a mixture supply hose and cooling at the upper or lower end. The formation of a section that can be rubbed by the trunk line or contact with the hot water connection hose is prevented, so that the mixing supply hose can be moved smoothly, and there is no end formation at the front end and the lower end of the main body housing 102 due to the guide taper. It is possible to move more stably by preventing and guiding the supply hose from being jammed in the process of entering the upper and lower parts.

That is, if the guide taper 106 is not configured, the front and bottom ends of the interference-preventing through hole 104 and the main housing 102 are formed with ends of a thickness equal to the thickness, and the mixed supply hose that is normally drawn out due to the formation of the end ( As 3) is composed of a flexible corrugated connector, if the corrugated part in the transverse direction is caught on the end, it is difficult to withdraw and return. Therefore, the guide tape 106 is for minimizing the jamming of the end of the mixing supply hose 3 as described above.

The first embodiment is configured to minimize the end jamming through the guide taper 106 by forming the pull-out and return interference preventing device 100 to correspond to the inner depth of the tubular fastening portion 9 in a cylindrical shape, that is, the upper and lower heights. However, as it is fitted to the tubular fastening portion 9 through force fitting, there may be a risk of separation. Accordingly, as shown in FIG. 8, a plurality of irregularities are formed in the main housing 102, but the shape of the irregularities is formed in a wedge shape to minimize deformation or breakage of the cold and hot water connection hose when forced-fitting. It is configured to prevent separation by being engaged with the inner periphery of the tubular joint and the outer periphery of the cold and hot water connection hose.

<Example 2>

9 and 10, a pull-out and return interference prevention device 100 in a cylindrical shape in which the wedge fastening part 200 is integrally formed, and a pull-out and return interference prevention device in the ring-shaped wedge fastening part 200 Is eccentrically coupled to one side from the central axis. Here, the pull-out and return interference prevention device 100 is eccentrically formed integrally with the wedge fastening part 200 to allow the cold and hot water connection hoses 1 and 2 to be installed inside the tubular fastening part 9. This is to secure the maximum space in the process of introducing the cold and hot water connection hoses (1, 2) into the interior so that the cold and hot water connection hoses can be easily installed, and the installation process of the cold and hot water connection hoses that are combined into a single bundle. It is possible to shorten the construction time by installing more conveniently in the.

For example, if the withdrawal and return interference prevention device 100 is located at the center of the wedge fastening part 200 and is coupled, a separate connecting rib must be additionally configured, as well as a lead-in space for introducing cold and hot water connection hoses into the tubular fastening part. As it is divided symmetrically on both sides, and the incoming space area is minimized, there is a problem of having to separate and combine the cold and hot water connection hoses and increase the construction time or installation time. Since there is no hassle to disassemble the whole, the withdrawal return interference prevention device 100 is configured such that one side of the outer circumference is integrally coupled to the inner circumference of the wedge fastening part 200, so that it can be drawn into the tubular fastening part. It is possible to secure the maximum available space, and accordingly, it is easy to install a connection hose for cold and hot water, and it can be easily performed during maintenance as well. Moreover, since there is no need for a separate connection rib configuration for integrally forming the withdrawal and return interference prevention device 100 in the wedge fastening part 200, the configuration is also simple, so that productivity can be improved.

When the wedge fastening part 200 is integrally formed with the pull-out return interference preventing device 100, when the wedge fastening part 200 is placed on the same axis toward the lower end of the tubular fastening part 9, the pull-out return interference preventing device 100 ) Is located on one side of the inner periphery of the tubular fastening portion (9). Thereafter, the wedge fastening part 200 is fitted in correspondence with the inner circumference of the lower end of the tubular fastening part. At this time, the wedge protrusion 202 is fitted while eroding the inner circumferential wall of the tubular fastening part 9 by a plurality of wedge protrusions 202 formed on the outer periphery of the wedge fastening part, and then tubular fastening by the wedge protrusion 202 It does not deviate to the load side and is firmly coupled.

Therefore, the withdrawal return interference prevention device 100 is located on one side of the inner periphery of the tubular fastener through the above coupling, and is coupled to the opposite side to the cold and hot water connection hose, so that the mixed supply hose 3 acts as in the first embodiment described above. Thus, the withdrawal and return of the mixed supply hose can be smoothly performed without difficulty due to interference or friction caused by contact with the cold and hot water connection hose. Accordingly, by configuring the wedge fastening portion 200 of the second embodiment rather than the first embodiment, the coupling of the pull-out and return interference prevention device is made more robust, so that a stable pull-out and return of the mixed supply hose is possible. However, in the case of Example 1, the ease of replacement is secured, faster installation construction is possible, and installation is easy, but there may be some problems due to separation from the tubular fastener, and Example 2 is the installation construction. It is simple, fast, and there is no problem due to separation from the tubular fastening part, but there is a part where the ease of replacement due to wedge bonding is low, so it is desirable to perform customized construction according to the site situation.

In the above, the present invention has been described in detail as an embodiment, but the scope of the present invention is not limited thereto, and it is obvious that a number of modifications and modifications can be made to those of ordinary skill within the scope of the technical idea. It will be included to the practical equivalent range with the embodiment of the. The technical features will be described in detail.
