Description

This disclosure relates to a faucet and a method for manufacturing the same.

Conventional faucets are known in a variety of configurations. For example, a sensor-equipped faucet used in the kitchen that uses a sensor to turn water on and off is known (Patent Document 1).

JP 2020-111973 A

However, conventional sensor-equipped faucets require the sensor to be built inside the cover, which results in a large outer diameter for the cover. If the outer diameter of the cover is reduced by modifying the internal structure, it becomes difficult to assemble the sensor.

The purpose of this disclosure is to solve the above problems by providing a faucet manufacturing method and a faucet that can be easily assembled even with a faucet cover that has a small outer diameter.

In order to solve the above problem, one aspect of the present disclosure is a method for manufacturing a faucet. The faucet comprises a cylindrical cover, an internal member disposed inside the cover, a hose housed in the internal space of the internal member so that it can be pulled out, a head portion having a water outlet connected to the tip of the hose, and a sensor disposed on the outer surface of the internal member. The internal member has a main body portion and a holder to which the head portion is attached. The holder has a concave guide portion on its outer surface that is longer than the sensor. The cover has a sensor positioning portion. In the method for manufacturing the faucet, after disposing the main body portion inside the cover, the sensor is placed on the main body portion side of the guide portion, and the holder is inserted through an opening of the cover, so that the sensor engages with the sensor positioning portion while moving along the guide portion and is positioned.

In order to solve the above problems, a faucet according to one embodiment of the present disclosure comprises a cylindrical cover, an internal member disposed inside the cover, a hose housed in the internal space of the internal member so that it can be pulled out, a head portion having a water outlet connected to the tip of the hose, and a sensor disposed on the outer surface of the internal member. The internal member has a main body portion and a holder to which the head portion is attached. The holder has a concave guide portion on its outer surface that is longer than the sensor. The sensor placed on the guide portion engages with a sensor positioning portion formed on the inside of the cover.

This disclosure allows for easy assembly even for faucets with covers that have a small outer diameter.

Below, an embodiment of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to this embodiment.

(Embodiment)
The faucet 1 shown in Figures 1 and 2 is a single-lever faucet device with a sensor for use in the kitchen. As shown in Figure 1, the faucet 1 includes a head portion 2, a cover 3, a faucet body 4, a lever 5, a sensor 6, and an electronic water discharge device (not shown) that controls water discharge ON/OFF based on detection by the sensor 6.

The head unit 2 is a member having a water outlet 21 formed at the tip end (downstream side) for discharging hot and cold water. The main part of the head unit 2 is a tubular (cylindrical in this embodiment) resin member (hereafter referred to as tubular member 20) with an internal flow path. Two types of water outlet forms for hot and cold water are available for use from the water outlet 21 of the head unit 2: straight water outlet, which is a single water flow, and shower water outlet, and the user can select and switch between either form when using the device. A push button 22 is attached to the rear side of the tubular member 20 of the head unit 2. By operating the push button 22, it is possible to switch between the two types of water outlet forms from the water outlet 21, straight water outlet and shower water outlet.

The tip (downstream end) of the hose 8 (see FIG. 4) is connected to the upstream side of the head portion 2. The hose 8 is made of a flexible material such as rubber. The head portion 2 is not limited to being made of resin. The head portion 2 (tubular member 20) does not have to be formed in a cylindrical shape. The head portion 2 (tubular member 20) does not have to be formed of resin. The tube connected to the head portion 2 is not limited to being a flexible hose 8.

The head unit 2 is configured to be retractable from the cover 3. That is, the head unit 2 can be selectively attached to the tip (downstream end) of the cover 3 or detached from the tip of the cover 3. When the head unit 2 is pulled out downstream (downstream in the direction of hot and cold water flow) from the tip of the cover 3, the hose 8 connected to the head unit 2 is also pulled out downstream from the tip of the cover 3 together with the cover 3. Note that the head unit 2 does not necessarily have to be configured to be detachable from the cover 3.

The faucet body 4 is positioned upstream of the cover 3. Inside the faucet body 4, a water supply pipe, a hot water supply pipe, a mixed water pipe, and a hot and cold water mixing cartridge (not shown) are housed. By operating the lever 5, the hot and cold water mixing cartridge adjusts the mixing ratio of hot water and cold water to create mixed water of the desired temperature and flow rate.

As shown in Figures 3, 4, and 5, the faucet 1 comprises an internal member 7 disposed inside the cover 3, and a hose 8 housed in the internal space 73 of the internal member 7. The cover 3 is cylindrical and made of resin. Specifically, in this embodiment, as shown in Figures 1 and 2, the cover 3 is a bowed cylinder with an outer diameter of 28 to 33 mm, and its surface is metal plated. Here, for convenience, the direction indicated by the symbol 30 in Figures 1 and 2 is defined as the axial direction of the cover 3. The axial direction of the cover 3 is the longitudinal direction in which the cover 3 extends, and is also the direction in which hot and cold water flows inside.

The cover 3 is not limited to being a resin molded product, but may be a resin molded product that contains a material other than resin, such as metal, in part, or may be made of a material that does not contain resin. The outer diameter of the cover 3 is not limited to 28-33 mm. The thickness of the cover 3 is preferably 2-4 mm, but may be 1-5 mm, etc., and is not particularly limited. The cover 3 is not limited to being a curved cylinder, but may be formed into a shape that combines straight cylinders, or a curved non-cylindrical cylinder, such as a curved elliptical cylinder.

The internal member 7 is a cylindrical resin molded product disposed inside the cover 3. The internal member 7 serves as an electrical component holding member that holds electrical components described below. The internal member 7 is disposed inside the cover 3, and positions the electrical components disposed inside the cover 3 at predetermined positions relative to the cover 3. The internal member 7 also serves as a hose holding member that holds a hose 8. The internal member 7 also serves as a sensor holding member that holds a sensor 6 separate from the electrical components. As shown in FIG. 3, the internal member 7 has a cylindrical main body 75, which is the main component, and a holder 74 to which the head portion 2 is attached. The internal member 7 does not have to be a resin molded product, and may be formed of a material other than resin, such as metal.

The main body 75 has a cylindrical base 70, which is the main component. The base 70 contacts the inner surface of the cover 3 and extends along the axial direction 30. In other words, the longitudinal direction of the base 70 is the same as the longitudinal direction of the cover 3. The holder 74 will be described later. The hose 8 is housed in the internal space 73 of the internal member 7. The hose 8 is connected to the head portion 2 and the mixed water pipe. The connector 62, which is an electrical member, is disposed on the outer surface of the internal member 7. The connector 62 connects the electronic water discharge device (not shown) to the wiring from the sensor 6.

4 and 5, the main body 75 has a first standing wall 71 and a second standing wall 72 at a height such that the tip portion contacts the inner surface of the cover 3. The first standing wall 71 and the second standing wall 72 are spaced apart from each other in the circumferential direction 300 and protrude from the base 70 to the outside in the radial direction (direction perpendicular to the circumferential direction 300) of the cover 3 and the base 70. The first standing wall 71 and the second standing wall 72 extend along the longitudinal direction (axial direction 30) of the base 70. The first standing wall 71 and the second standing wall 72 extend in the same direction. That is, the first standing wall 71 and the second standing wall 72 protrude in parallel from the base 70. In addition, the first standing wall 71 and the second standing wall 72 extend in parallel in the longitudinal direction (axial direction 30) of the base 70. Note that the first standing wall 71 and the second standing wall 72 do not necessarily have to protrude in parallel from the base 70. Furthermore, the first standing wall 71 and the second standing wall 72 do not necessarily have to extend parallel to each other in the longitudinal direction of the base 70.

The tips of the first standing wall 71 and the second standing wall 72 are in contact with the inner surface of the cover 3. Note that it is not necessary for both tips of the first standing wall 71 and the second standing wall 72 to be in contact with the inner surface of the cover 3; it is sufficient that the tip of either the first standing wall 71 or the second standing wall 72 is in contact with the inner surface of the cover 3.

The outer surface of the base 70 opposite the first standing wall 71 and the second standing wall 72 is in contact with the inner surface of the cover 3. This allows the main body 75 to be supported at three points: the first standing wall 71, the second standing wall 72, and the outer surface opposite the first standing wall 71 and the second standing wall 72. Note that a third standing wall and a fourth standing wall that are in contact with the inner surface of the cover 3 may protrude from the outer surface of the base 70 opposite the first standing wall 71 and the second standing wall 72. The third standing wall and the fourth standing wall protrude in a direction opposite to the protruding direction of the first standing wall 71 and the second standing wall 72 from the base 70.

A thin wall portion 32 is formed between the first standing wall 71 and the second standing wall 72 in the circumferential direction 300 of the cover 3. The thickness of the thin wall portion 32 is thinner than the thickness of other parts of the thin wall portion 32 of the cover 3 in the circumferential direction 300. The thin wall portion 32 may be formed over the entire length between the first standing wall 71 and the second standing wall 72 in the circumferential direction 300 of the cover 3, or may be formed in a part between the first standing wall 71 and the second standing wall 72. The thin wall portion 32 may be formed only in a part of the axial direction 30 between the first standing wall 71 and the second standing wall 72 of the cover 3, or may be formed over the entire length of the axial direction 30.

At the thin-walled portion 32, the outer surface of the cover 3 is not recessed, but the inner surface is recessed relative to the adjacent portion. Specifically, in this embodiment, the thickness of the cover 3 at the thin-walled portion 32 is 1.1 to 1.4 mm, and the thickness at other portions is 2.3 to 2.7 mm, but the thickness of the cover 3 is not limited to these numerical values. The connector 62 is located on the outer surface of the base 70, between the first standing wall 71 and the second standing wall 72.

The electrical member (connector 62) is located on the outer surface of the base 70 at a location between the first standing wall 71 and the second standing wall 72. The electrical member (connector 62) is attached to the outer surface of the base 70 by an appropriate method such as screwing, gluing, or fitting.

By making the thickness of the thin-walled portion 32 thinner than the thickness of other portions of the cover 3, the gap between the inner surface of the cover 3 (the portion where the thin-walled portion 32 is formed) and the internal member 7 can be made wider. In addition, the first standing wall 71 and the second standing wall 72 contact the thin-walled portion 32 to support it, so that the strength of the cover 3 can be maintained while ensuring space to accommodate the connector 62.

The connector 62 is in contact with the inner surface of the cover 3 (the portion where the thin-walled portion 32 is formed). This makes it easier to fit the electrical component (connector 62) in the limited space inside the cover 3 without making the cover 3 larger, compared to when the thin-walled portion 32 is not formed on the cover 3. In addition, the cross section of the inner surface of the cover 3 at the location where the connector 62 is disposed (a cross section perpendicular to the axial direction 30 in which the cylindrical cover 3 extends) has a trapezoidal shape for the thin-walled portion 32, and the other portions of the thin-walled portion 32 in the circumferential direction of this cross section are circular.

The cover 3 has a sensor positioning portion that positions the sensor 6. The sensor positioning portion is an opening 34 formed in the cover 3.

The sensor 6 is disposed on the outer surface of the internal member 7. Specifically, the sensor 6 is disposed on the outer surface of the base 70 of the main body 75 of the internal member 7.

The sensor 6 is a device that detects an object. The sensor 6 is, for example, an infrared detection device having an infrared sensor, and is equipped with an infrared transmitter and receiver, and detects the presence or absence of a user's hand or the like as an object. The sensor 6 may be a detection device that uses a laser or the like instead of an infrared sensor.

The holder 74 is a member for attaching the head portion 2. The holder 74 is a cylindrical resin molded product. The holder 74 extends in the axial direction 30, similar to the base portion 70. The holder 74 is detachable from the main body portion 75 (base portion 70). The upstream end of the holder 74 (upstream of the hot and cold water flowing through the hose 8) is detachably attached to the downstream end of the main body portion 75 (base portion 70).

The holder 74 has an upper holder 76 and a lower holder 77 that extend in the axial direction 30 and are divided in the radial direction (particularly in the up-down direction). Both the upper holder 76 and the lower holder 77 are semi-cylindrical.

The holder 74 has a concave guide portion 82. The holder 74 has a first rib 761 and a second rib 762 that protrude radially outward from a cylindrical base. The first rib 761 and the second rib 762 protrude from each other at a distance in the circumferential direction 300. The portion of the holder 74 between the first rib 761 and the second rib 762 in the circumferential direction 300 forms the guide portion 82. The guide portion 82 is longer than the sensor 6 in the axial direction 300.

Next, we will explain how to attach the holder 74 to the cover 3.

As shown in Figures 3 to 8, the faucet 1 comprises a cylindrical cover 3, an internal member 7 disposed inside the cover 3, a hose 8 housed in an internal space 73 of the internal member 7 so that it can be pulled out, and a head portion 2 equipped with a water outlet 21 connected to the tip of the hose 8. As shown in Figures 6 to 8, the holder 74 has an upper holder 76 and a lower holder 77 which are separated. The head portion 2 is detachable from the holder 74, and water can be discharged whether the head portion 2 is fixed to the holder 74 or removed from the holder 74.

As shown in FIG. 9, the upper holder 76 and the lower holder 77 are connected to form the holder 74 so that the hose 8 already connected to the head unit 2 is housed in the internal space 73, and then the holder 74 is inserted into the opening 31 at the tip of the discharge side of the cover 3 and fixed in place. The holder 74 can be attached to the cover 3 even after the hose 8 has been stored in the cover 3.

The lower holder 77 is fixed to the cover 3 with screws 35 (see FIG. 2). As shown in FIG. 6, the upper holder 76 has a hook structure that prevents the upper holder 76 from sliding (displacing) downward relative to the lower holder 77. The hook structure is formed by a protrusion 78 formed on the upper holder 76 that faces diagonally downward and forward, and a recess 79 formed on the lower holder 77 that fits snugly into the protrusion 78. The upper holder 76 and the lower holder 77 are not fixed with adhesive, and the lower holder 77 is fixed to the cover 3 by fixing the lower holder 77 to the cover 3 with screws 35, and the upper holder 76 engages with and is fixed to the upper holder 76 by the hook structure.

As shown in Figures 9 and 10, the inner surface of the cover 3 has a concave groove 33 extending in the axial direction of the cover 3 on both the left and right sides. As shown in Figure 7, the upper holder 76 has a convex rib 81 that fits into the concave groove 33 at the left and right ends. With this configuration, even a faucet 1 with a small outer diameter of the cover 3 can be easily assembled. In addition, the convex rib 81 is provided on the upper holder 76, and fits into the concave groove 33, preventing the upper holder 76 from tilting. Furthermore, when the head portion 2 is attached to the holder 74, a load from the front on the head portion 2 causes the holder 74 to tilt, preventing the holder 74 from jumping out of the cover 3.

Next, we will explain how to install the sensor 6.

The faucet 1 comprises a cylindrical cover 3, an internal member 7 disposed inside the cover 3, a hose 8 housed in an internal space 73 of the internal member 7 so that it can be pulled out, a head portion 2 equipped with a water outlet 21 connected to the tip of the hose 8, and a sensor 6 disposed on the outer surface of the internal member 7. The internal member 7 has a holder 74 to which the head portion 2 is attached, and a main body portion 75.

As shown in Figures 6, 7, 11, and 12, the holder 74 has a concave guide portion 82 on its outer surface that is longer than the sensor 6. As shown in Figure 11, the cover 3 has a sensor positioning portion on its inner side. Here, the sensor positioning portion is the opening 34 for the sensor 6 that is provided in the cover 3.

After the main body 75 is placed inside the cover 3, the sensor 6 is attached to the faucet 1 by placing the sensor 6 on the main body 75 side (upstream side along the axial direction 30) of the guide 82, and inserting the holder 74 through the opening 31 of the cover 3. Although not shown in Figures 11 and 12, the sensor 6 is connected to the connector 62 by wiring. The sensor 6 is positioned by engaging with the opening 34, which is the sensor positioning portion, while moving along the guide 82. Since the guide 82 is closer to the cover 3 on the head 2 side than on the main body 75 side, the sensor 6 is gradually pressed against the cover 3 by the guide 82 as the holder 74 is inserted into the cover 3. In this way, even a faucet 1 with a cover 3 having a small outer diameter can be easily assembled. The faucet 1 can also be easily disassembled.

As shown in FIG. 3, the holder 74 may be inserted into the cover 3 with the gasket 63 disposed on a portion of the surface of the sensor 6.
