Description

  The present invention relates to a method of attaching a faucet device to furniture with a water tank.

  In furniture with a water tank that receives water used for hand-washing or drawing water in a water tank such as a bathroom vanity, a structure in which a faucet device is attached to a standing wall provided close to the water tank is widely adopted.

  Patent Document 1 below discloses a structure in which a standing wall (wall surface 3) is provided on the back side of a water tub (ball 2) in a vanity and a water supply pipe is disposed on the back side of the standing wall. The water tank side end of the water supply pipe passes through a through hole (attachment opening 9) formed in the standing wall and is pulled out to the front side, and is connected to the faucet body. The faucet body is attached to the front surface of the standing wall portion via an attachment fitting or the like. Thereby, the operation of connecting the faucet body and the water supply pipe and the operation of attaching the faucet body to the standing wall can be performed only on the front side of the standing wall.

Japanese Patent Laid-Open No. 9-144083

  In general, furniture with a water tank such as a vanity is installed such that the back surface of the furniture comes into contact with a building wall. Therefore, when a vanity having a water tank and a standing wall standing on its back side is arranged so that its back surface comes into contact with the building wall, the water supply pipe is placed between the standing wall of the vanity and the building wall. It will be arrange | positioned in the clearance gap formed.

  In order to shorten the distance between the building wall and the standing wall and to make the vanity compact, it is preferable to make the gap small. However, if the gap is reduced, the water supply pipe must be routed through the small gap after the rear face of the vanity is placed in contact with the building wall. Therefore, as in Patent Document 1, it is very difficult to pull out the end of the water supply pipe from the through hole of the standing wall to the front side. In particular, a water supply pipe to which a so-called primary pressure is applied is often a pressure hose that can withstand high pressure because of safety requirements, and it is difficult to ensure sufficient flexibility for handling. If the end of the pressure hose having poor flexibility is pulled out from the through hole to the front side, the operation becomes more difficult.

  As a method for facilitating the installation work of the water supply pipe, it is considered that the water supply pipe is previously arranged on the back side of the standing wall of the bathroom vanity before installing the bathroom vanity in contact with the building wall. It is done. This is because the installation work of the water supply pipe is performed in a sufficient work space before installing the vanity.

  However, according to laws and regulations, only those who have a predetermined qualification (persons who are qualified for waterworks) can perform the operation of arranging the water supply pipe so that water can be supplied from the water supply pipe. In some cases, the vanity of the bathroom vanity does not go through a qualified person for waterworks, and the installation contractor who installs the vanity (unqualified person for waterworks) and the distributor who installs the water supply pipe (qualified for waterworks) Often) are different. In such a case, the installer first carries the vanity to the site, and once the vanity is brought into contact with the building wall, it is fixed. At a different timing from the fixing work, the installer removes the screws fixing the vanity to the building wall, pulls the vanity away from the building wall, and then installs the water pipe. The vanity must be re-fixed against the building wall.

  In order to avoid the troublesome work as described above, the water supply pipe is passed from the front side to the through-hole of the standing wall portion without moving the vanity that has been installed in contact with the building wall by the installer. A method of arranging the water supply pipe in the gap between the standing wall portion and the building wall can be considered. However, in this method, there is a possibility that the inserted water supply pipe interferes with the building wall and damages the building wall. That is, when a pressure hose is used for the water supply pipe as described above, when a pressure hose with poor flexibility is inserted into the through hole from its end, the end strongly interferes with the building wall, There is a risk of scraping.

  The present invention has been made in view of such a problem, and the purpose thereof is to damage the building wall even if the furniture with a water tank such as a vanity is still fixed to the building wall. An object of the present invention is to provide a method of attaching a faucet device to furniture with a water tub, which can be easily attached.

  In order to solve the above-mentioned problem, the method of attaching a faucet device to furniture with aquarium according to the present invention is characterized in that the furniture with aquarium has a standing wall that is erected so that the back faces the building wall with a gap, A counter provided with a water tank provided on the front side of the standing wall for receiving water, the faucet device attached to the standing wall, and a cabinet provided with a pair of left and right side plates and provided below the standing wall, The water faucet device has a water supply pipe for supplying water, a hot water supply pipe for supplying hot water, and a hot and cold water mixing tap for connecting the water supply pipe and the hot water supply pipe to which hot water and water supplied are mixed. At least one of the water supply pipe and the hot water supply pipe is a pressure hose, the first step of attaching the counter directly or indirectly to the building wall, and the hot water / water mixing tap is arranged on the front side of the standing wall. Established On the other hand, the water supply pipe and the hot water supply pipe are arranged on the through hole formed in the vertical wall from above the front side of the through hole so that the water supply pipe and the hot water supply pipe are arranged on the back side of the vertical wall. A second step of inserting obliquely downward toward the rear region of the water tank that is behind the water tank, and the ends of the water supply pipe and the hot water supply pipe are lower than the water tank when the second process is completed. It has reached the storage space of the said cabinet located in the side.

  The method of attaching the faucet device to the furniture with a water tank according to the present invention includes inserting a water supply pipe and a hot water supply pipe obliquely from above the front side toward the rear region of the water tank behind the standing wall, Interference between the end of the hot water supply pipe and the building wall is suppressed. Therefore, even if at least one of the water supply pipe and the hot water supply pipe is a pressure-resistant hose having poor flexibility, it is disposed on the back side of the standing wall without damaging the building wall by each end, and the faucet device is installed on the standing wall. It can be easily attached from the front side. For this reason, even if the installer who installs furniture with water tanks is different from the installer who arranges water supply pipes and hot water supply pipes, after the installer installs furniture with water tanks, Arrangement work can be performed without moving attached furniture.

  Moreover, unlike the known technology, it does not require the difficult work of pulling out the end of each of the water supply pipe and hot water supply pipe from the rear side of the standing wall to the front side, and it also installs a connection between the end and the hot water mixing tap Since it is not necessary to perform on-site, the faucet device can be easily attached.

  Moreover, in the method of attaching a faucet device to furniture with a water tank according to the present invention, the faucet device may have a flange that covers a gap between the through hole and the hot and cold water mixing faucet from the front side of the standing wall. preferable.

  In this preferred aspect, the through hole is formed large so that the water supply pipe and the hot water supply pipe can be inserted in an oblique direction, and a flange for covering a gap formed between the through hole and the hot water mixing tap is provided in the water faucet device. Since they are integrated, there is no need to newly add a member for covering the gap formed between the through hole and the hot and cold water mixing tap. Therefore, it becomes possible to avoid complication of construction.

  Moreover, in the method for attaching the faucet device to the furniture with a water tank according to the present invention, it is also preferable that the through hole is a long hole extending in the vertical direction.

  In this preferred embodiment, the flange that covers the gap between the through hole and the hot and cold water mixing tap does not widen laterally, so that the flange is less conspicuous and the design is not impaired. Further, since the flange does not spread sideways, it is possible to make it difficult for water to collect at the upper end of the flange.

  In the method of attaching a faucet device to furniture with a water tank according to the present invention, it is also preferable that the hot and cold water mixing faucet is disposed at a position offset upward from the center of the flange.

  In this preferred embodiment, the flange is less noticeable.

  Further, in the method of attaching the faucet device to the furniture with a water tank according to the present invention, the rear side rail provided between the side portions of the pair of side plates on the building wall side, and provided above or below the rear side rail. A back plate, and a step suppressing portion that connects the building wall and the back side rail and the front surface of the back plate without a step above at least one of the back horizontal rail and the back plate. It is also preferable to provide

Moreover, as shown in FIG.2 and FIG.3, the back crosspiece 34 is provided between the side parts by the side of the washroom wall W of the side plates 31L and 31R so that each may be connected. By these side plates 31L and 31R, the door 32, the bottom plate 33, and the rear horizontal rail 34, the cabinet 30 has a box shape that forms a storage space 35 therein. The user of the vanity 1 can open and close the door 32 to approach the storage space 35 from the front and store or take it out. Further, a back plate 36 having a thickness smaller than that of the rear horizontal beam 34 is provided between the pair of side plates 31L and 31R and below and in front of the rear horizontal beam 34, and the user opens the door 32. The washroom wall W is covered so that it cannot be seen through the storage space 35. Further, at least one of the rear horizontal bar 34 and the back plate 36 is provided with a step suppressing portion 39 that connects the washroom wall W and the front surface of the rear horizontal bar 34 and the back plate 36 without a step. This level | step difference suppression part 39 has connected the front surface of the upper part of the back horizontal crosspiece 34, and the washroom wall W without a level | step difference by the inclined surface.

  As shown in FIG. 2, the water faucet device 40 includes a hot and cold water mixing tap 41, a water supply pipe 42 c connected to the hot water and water mixing tap 41, a hot water supply pipe 42 h, a flexible hose 42 f, and a water discharge section connected to the flexible hose 42 f. (In FIG. 2, since the water supply pipe 42c and the hot water supply pipe 42h are superposed in the direction perpendicular to the paper surface, only the water supply pipe 42c on the near side is displayed).

  Each of the water supply pipe 42c and the hot water supply pipe 42h is a pressure-resistant hose having high pressure resistance, and is connected to the hot-water mixing plug 41 via the metal elbows 43c and 43h at the upper ends, respectively, and extends downward. . Cap nuts 44c and 44h are provided at the lower ends of the water supply pipe 42c and the hot water supply pipe 42h, respectively. The water supply pipe 42c is connected to a water stop cock 37 provided in the storage space 35 of the cabinet 30 through the cap nut 44c so as to allow water to pass therethrough. The hot water supply pipe 42h is connected so that the cap nut 44h is connected to a hot water supply device (not shown) disposed in the storage space 35 and is supplied with hot water.

  The hot and cold water mixing tap 41 mixes hot water and water supplied from the water supply pipe 42c and the hot water supply pipe 42h into the interior thereof. As will be described later, a part of the hot and cold water mixing tap 41 is inserted into the through hole 14 formed in the standing wall 11 of the counter 10 and is disposed on the front side of the standing wall 11. A lever-like handle 46 is provided on the front side of the hot-water mixing tap 41. The user operates the handle 46 to change the ratio of hot water and water flowing into the hot and cold mixing tap 41, supply or stop the mixed hot water to the flexible hose 42f, and the flow rate of the hot water to be supplied. It is possible to make changes. The hot and cold water mixing tap 41 is integrally provided with a flange portion 47.

  The water discharge part 45 is detachable from the front side of the standing wall 11 of the counter 10, and the user can cause the water discharge to be performed at a desired position by removing the water discharge part 45 from the standing wall 11. The water discharge portion 45 is connected to a flexible hose 42 f disposed on the back side of the standing wall 11 through an opening (not shown) formed in the standing wall 11 separately from the through hole 14. The water discharger 45 can discharge hot water supplied from the flexible hose 42f in various forms such as showering and rectification.

  The flexible hose 42f is a hose having higher flexibility than the water supply pipe 42c and the hot water supply pipe 42h, and most of the flexible hose 42f is disposed on the back side of the standing wall 11 when the water discharge portion 45 is attached to the standing wall 11. . On the other hand, if the water discharge part 45 is removed from the standing wall 11, it will be drawn to the front side from the opening (not shown) formed in the standing wall 11 in connection with it. The hot water mixed by the hot water mixing tap 41 is supplied to the water discharge part 45 through this flexible hose 42f.

In the vanity configured as described above, the through hole 14 formed in the standing wall 11 is perpendicular to the through hole 14 in order to simultaneously insert the water supply pipe 42c, the hot water supply pipe 42h, and the flexible hose 42f in an oblique direction. It is formed larger than the case of inserting from the direction.
Thereby, with respect to the through hole 14, the water supply pipe 42c and the hot water supply pipe 42h can be inserted obliquely from the upper front side of the through hole 14 toward the rear region 15 of the water tank 12 behind the standing wall 11. It is. The ends of the water supply pipe 42c and the hot water supply pipe 42h inserted in an oblique direction hardly interfere with the washroom wall W, and do not damage the washroom wall W at the end of the water supply pipe 42c and the hot water supply pipe 42h. And it can arrange | position to the back side of the standing wall 11 without difficulty. For this reason, a gap is formed between the large through-hole 14 and the hot / cold mixing tap 41, but the gap is covered from the front by a flange 47 provided in the hot / cold mixing tap 41.

  For example, as shown in FIG. 3, the through-hole 14 is a vertically long slot whose height in the vertical direction is larger than the width in the horizontal direction. Thereby, the flange 47 does not need to be greatly expanded from side to side with respect to the hot and cold mixing tap 41. Further, the hot and cold water mixing tap 41 is disposed so as to be biased upward relative to the flange 47. As a result, most of the flange 47 is located below the hot-water mixing tap 41, and the flange 47 is behind the hot-water mixing tap 41 and the handle 46, so that the flange 47 is less noticeable.

  Next, with reference to FIG.4 and FIG.5 in addition to FIG.2, 3, the attachment process to the standing wall of a water tap apparatus is demonstrated. FIG. 4 is a cross-sectional view immediately after insertion of the faucet device of the vanity according to the embodiment of the present invention, and FIG. 5 is a cross-sectional view of the vanity table according to the embodiment of the present invention during insertion of the faucet device. is there.

<First step>
First, the bathroom vanity 1 is moved and the back surface thereof is placed in contact with the bathroom wall W.

<Second step>
Next, as shown in FIG. 4, the water supply pipe 42c, the hot water supply pipe 42h, and the flexible hose 42f of the faucet device 40 are pushed through the cap nuts 44c, 44h, and 44f provided at the end portions thereof. 14 is inserted. Since the water supply pipe 42c and the hot water supply pipe 42h are pressure-resistant hoses with poor flexibility, it is difficult to bend only a part of them and insert them into the through holes 14. Therefore, at the time of insertion, the water supply pipe 42c, the hot water supply pipe 42h, and the flexible hose 42f are pushed obliquely downward from above the front surface portion of the standing wall 11 toward the rear region 15 of the water tank 12 behind the standing wall 11.

  The cap nuts 44c, 44h, 44f that have passed through the through-hole 14 are pushed obliquely downward when the water supply pipe 42c or the like is pushed in, so that they reach the rear region 15 behind the water tank 12 without hitting the washroom wall W. To do. Further, when the water supply pipe 42c or the like is pushed in, the end portion of the water supply pipe 42c or the like is not caught by the upper end 34T of the rear horizontal beam 34 by the step suppressing portion 39 attached to the upper end 34T of the rear horizontal beam 34. It reaches the front side, that is, the storage space 35 of the cabinet 30.

  When the faucet device 40 is pushed in until the flange portion 47 provided on the standing hot water / mixing tap 41 comes into contact with the peripheral edge of the through hole 14 of the standing wall 11, the flange portion 47 and the mounting bracket (not shown) are screwed. At this point, the installation of the faucet device 40 to the standing wall 11 is completed. At this time, the cap nuts 44 c, 44 h and 44 f are located in the storage space 35 of the cabinet 30.

  Next, the water supply pipe 42 c hanging from the storage space 35 of the cabinet 30 and the stop cock 37 are connected. Further, the hot water supply pipe 42h is connected to a hot water heater (not shown). Specifically, the water stopcock 37 and the water supply pipe 42c are supplied with water by screwing a cap nut 44c at the end of the water supply pipe 42c and a male screw portion 38 provided at the upper end of the water stopcock 37. Connected as possible. Further, by connecting a hot water outlet of a water heater disposed in the storage space 35 and a cap nut 44h at an end of the hot water supply pipe 42h, the hot water can be supplied.

  Further, the cap nut 44f at the end of the flexible hose 42f is connected to the end of the flexible hose 42f on the water discharge portion 45 side. That is, the flexible hose 42 f connects the part divided into the part connected to the hot and cold mixing tap 41 and the part connected to the water discharge part 45 in the storage space 35 of the cabinet 30. Thus, the attachment process of the faucet device 40 is completed by connecting the flexible hose 42f at the intermediate position.

  In the mounting process of the faucet device 40 as described above, the interference between the cap nuts 44c, 44h, 44f at the end of the water supply pipe 42c and the washroom wall W is a through-hole formed in the water supply pipe 42c and the like. It is suppressed by inserting diagonally downward from 14, and the water supply pipe 42c and the like can be disposed without damaging the washroom wall W severely. Therefore, even if the water supply pipe 42c and the hot water supply pipe 42h are pressure-resistant hoses with poor flexibility, the damaged washroom is not damaged by the bag nuts 44c and 44h provided at the respective ends without damaging the washroom wall W. Without being caught by the wall W, it is arrange | positioned at the back side of the standing wall 11, and the faucet device 40 can be easily attached from the front side of a standing wall. For this reason, even if the installer who installs the vanity 1 and the installer who arranges the water supply pipe 42c and the hot water supply pipe 42h are different from each other, after the installer installs the vanity 1, It becomes possible for a trader to perform the disposition work without moving the vanity 1.

  Further, since the step suppressing portion 39 that connects the front surface of the rear horizontal beam 34 and the washroom wall W without a step is provided at the upper end 34T of the rear horizontal beam 34, water supply is performed during insertion into the through hole 14 of the standing wall 11. The pipe 42c and the hot water supply pipe 42h hang down, and the cap nuts 44c, 44h, 44f at the ends of the pipe 42c and the hot water supply pipe 42h are not caught on the upper end 34T of the rear side rail 34 of the cabinet 30. Therefore, it is possible to efficiently perform the installation work of the water supply pipe 42c and the hot water supply pipe 42h.

The embodiment of the method for attaching the faucet device to the furniture with a water tank according to the present invention has been described above with reference to a specific example of the vanity 1. However, the present invention is not limited to this embodiment.
For example, if the through-hole 14 is enlarged to such an extent that the water supply pipe 42c or the like inserted obliquely downward from the through-hole 14 can reach the front surface side of the back plate 36 of the cabinet 30 without hitting the washroom wall W, the level difference The suppressing unit 39 may not be provided. Further, although the number of manufacturing steps is increased, the flange 47 provided integrally with the hot / cold mixing tap 41 can be separated from the hot / cold mixing tap 14. Moreover, if the periphery of the through hole 14 of the standing wall 11 is an inclined surface whose upper side is inclined rearward, the spread of the through hole 14 can be suppressed.

  Further, those specific modifications made by those skilled in the art to these specific examples are also included in the scope of the present invention as long as they have the characteristics of the present invention. For example, the elements included in each of the specific examples described above and their arrangement, materials, conditions, shapes, sizes, and the like are not limited to those illustrated, but can be changed as appropriate. Moreover, each element with which each embodiment mentioned above is provided can be combined as long as technically possible, and the combination of these is also included in the scope of the present invention as long as it includes the features of the present invention.
