Abstract

PURPOSE:To allow a foreign object or a finger to be immediately removed when pinched by detecting the load of a water feed pipe when it is vertically moved and controlling a driving source to stop the water feed pipe after it is lifted when the load of the water feed pipe during its descent becomes the preset value or above. CONSTITUTION:When a descent switch 18 is turned on, whether the limit switch SW3 at the descent position is on is judged, if it is off, a motor 5 is rotated to lower a water feed pipe 3, and time counting is started. When the descent of the water feed pipe 3 is started, a fluctuation occurs in the current to the motor 5, thus no load detecting processing is performed for 0.3sec, for example, to allow descent. When an overload is detected after this time elapses, the motor 5 is reversely rotated for a fixed time to raise the water feed pipe 3. When no overload is detected, the motor 5 is stopped when the limit switch SW3 is turned on at the lowest position. When an overload is applied, the motor 5 is reversely rotated to raise the water feed pipe 3, even if a foreign object or a finger is pinched between the water feed pipe 3 and a guide tube 16, it can be immediately removed.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a washbasin with a shower, in which a shower device having a shower head provided at the upper end of a water supply pipe that is moved up and down by a drive source is arranged at key points around a washbowl.

[Conventional technology]

2. Description of the Related Art Conventionally, a washbasin with a shower has been provided in which a shower device, in which a water supply pipe having a shower head at the upper end is moved up and down by a drive source, is disposed around a washbowl.

[Problem to be solved by the invention]

As in the above configuration, when the shower head is moved up and down by the drive source, the driving force is large, so it is dangerous to get your fingers etc. stuck in the protruding part of the water supply pipe, and if a foreign object gets caught, the drive source There may also be a problem that the drive source may burn out due to a large load being applied to the drive source. To solve this problem, we have developed a system that detects when external loads are applied to the water supply pipe or shower head, such as when a foreign object or finger gets stuck in the protruding part of the water supply pipe, and stops the drive source. It is possible to do so. However, simply stopping the device causes a problem in that the foreign object or finger remains trapped and cannot be removed. The present invention aims to solve the above-mentioned problems and provides a washbasin with a shower that allows foreign objects or fingers to be easily removed even if they get caught.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a load detection unit that detects the load when the water supply pipe moves up and down, and a load detection unit that detects the load when the water supply pipe moves up and down, and a load detection unit that detects the load when the water supply pipe moves up and down. A controller is provided to control the drive source so as to stop the drive source.

[Effect]

According to the above configuration, if a load of more than a predetermined value is applied from the outside while the water supply pipe is descending, the water supply pipe is raised and then stopped, so even if a foreign object or a finger gets caught, the shower head will not move. It quickly rises from its position and can easily remove foreign objects and fingers.

【Example】

As shown in FIG. 1, the washstand 10 has a counter 1 on the top surface.
5, and a backboard 12 rising upward from the rear of the storage box 11, and the front of the backboard 12 has a cupboard 13. ! jfj, 14, etc. are provided. counter 15
A washbowl 1 is provided at the counter 15, and a water supply pipe 3 having a shower head 2 at its upper end protrudes behind the washbowl 1 at the counter 15. The shower head 2 is in a state where water is discharged from one spout having a relatively large diameter (
It can be switched between a straight faucet (straight) and a shower mode (shower) in which water is discharged from a large number of relatively small-diameter spouts, and is configured so that it can be used both as a normal faucet and a shower. As shown in FIG. 2, the water supply pipe 3 is inserted into a guide tube 16 fixed to the counter 15 and is movable up and down, and is moved up and down by a lifting device 4 disposed inside the storage box 11. Driven. Here, the water supply pipe 3 is connected so that the shower head 2 is always exposed from the counter 15.
The range of vertical movement of is regulated. Further, the counter 15 is used to select whether to raise or lower the water supply pipe 3.
A rise switch 17 and a fall switch 18 are provided. The lifting device 4 is housed in a housing 20 fixed at a fixed position within the storage box 11, and a motor 5 serving as a driving source is provided in the housing 20. The rotational output of the motor 5 is reduced by a reduction gear in a gearbox 21 to rotate a pulley 22. A freely rotating pulley 23 is disposed below the pulley 22, and both pulleys 22.
A belt 24 is hung on 23fm. The water supply pipe 3 is connected to the belt 24 via a connecting fitting 25 . That is, the connecting fitting 25 has a horizontal piece 25a fixed to the lower end of the water supply pipe 3, and a vertical piece 25b protruding downward from the edge of the horizontal piece 25a and fixed to the belt 24. When the belt 24 rotates around the pulleys 22 and 23 as a result of the rotation of the belt 5, the water supply pipe 3 moves up and down. A working piece 25c is protruded from the vertical piece 25b, and three limit switches SW1 to S are spaced apart from each other in the vertical direction.
W3 is pressed by the operation piece 25c. The limit switches SW, SW3 are arranged corresponding to the upper and lower end positions in the movement range of the water supply pipe 3, respectively, and the limit switch SW2 is located at an intermediate position between the other limit switches SW, SW, in the vertical direction. It is located in Therefore, when the water supply pipe 3 moves up and down with the rotation of the motor 5, the working piece 25c at each of the upper end position, intermediate position, and lower end position.
One of the limit switches SW1 to SW
3 is pressed to turn it on. Inside the housing 20, as shown in FIG.
A circuit section includes a load detection section 6 that detects a mechanical load that acts when the motor moves up and down, and a control section 7 that controls the motor 5 based on the load detected by the load detection section 6. equipped. The load detection section 6 detects a change in the current to the motor 5 to detect the state of the mechanical load. Further, the control section 7 is constituted by a programmable sequencer, and operates as follows. That is, when the rise switch 17 is turned on, the
, ), if the limit switch SWl corresponding to the upper end position of the water supply pipe 3 is not on, a time limit is started and the motor 5 is rotated so that the water supply pipe 3 is raised. Here, if the limit switch SW1 is on, the water supply pipe 3 is at the "1" end position and cannot be raised any further, so the motor 5 remains in a stopped state. When the water supply pipe 3 rises and the motor 5 starts, there is a fluctuation in the current to the motor 5, so the load detection process is not performed until the current fluctuation becomes negligible (for example, 0.3 seconds). to raise the water supply pipe 3. After this time has elapsed, if it is detected that the load is greater than a predetermined value (overload), the motor 5 is stopped. Unless it's overloaded,
Limit switch s at either intermediate position or upper end position
The motor 5 is stopped when w, , sw2 is turned on. In addition, even if the overload has not reached the intermediate position or the upper end position, the predetermined time (
If the motor 5 does not stop even after a period of 7 seconds (for example, 7 seconds) has elapsed, it is assumed that some abnormality has occurred and the motor 5 is stopped. As described above, if an overload is detected while the water supply pipe 3 is rising, the motor 5 is stopped to stop the water supply pipe 3 from rising. Further, if the rise switch] 7 is turned on when the water supply pipe 3 is at the lower end position, it will temporarily stop at the intermediate position, so if you want to raise it to the upper end position, just turn on the rise switch again. Here, if the lift switch is turned on twice in succession when it is at the lower end position, it will rise to the upper end position without stopping at the intermediate position, and the operability will be further improved. On the other hand, when the lowering switch 18 is turned on, as shown in FIG. 4(b).
As shown in , first, limit switch SW3 at the lower end position is
It is determined whether or not the motor 5 is on, and if it is on, the motor 5 is kept in a stopped state since the motor 5 cannot be lowered any further. Further, if the limit switch SW3 is off, the motor 5 is rotated so that the water supply pipe 3 is lowered. At the point when the vehicle starts descending, the time limit starts in the same way as when ascending. Since fluctuations occur in the current to the motor 5 when the water supply pipe 3 starts descending, the time (for example, 0.3 seconds) until the current fluctuation becomes negligible is as same as when ascending. Lower the load without performing load detection processing. If an overload is detected after this time has elapsed, the motor 5 is reversed for a certain period of time (for example, 0.3 seconds) to raise the water supply pipe 3. In addition, if an overload is not detected, the motor 5 is stopped when the limit switch SW at the lower end position is turned on. Even if the motor 5 continues to rotate even after a predetermined period of time (for example, 7 seconds) has elapsed since the start of the time limit, it is determined that there is some kind of abnormality and the motor 5 is stopped.As described above, when an overload is applied, Since the motor 5 is reversed to raise the water supply pipe 3, even if a foreign object or a finger gets caught between the water supply pipe 3 and the guide cylinder 16, it can be removed immediately, providing a high degree of safety and preventing overloads. It is also possible to prevent the motor 5 from burning out due to this.When descending, the motor 5 does not stop at an intermediate position, but is set so that it descends to the lower end position when the descending switch 18 is turned on once. The above-mentioned operation may be performed only below the center position, and if an overload is detected above the center position, only the stop is performed.Also,
The amount of load to be considered as an overload can be adjusted for both when ascending and when descending. In the above embodiment, the shower head 2 is always exposed on the upper surface of the counter 15 between the upper end position and the lower end position.
It is also possible to provide one lid plate that can be opened and closed freely, and to store the shower head 2 under the counter 15 at the lower end position. Furthermore, as shown in FIG. 5(b), the shower head 2 and the water supply pipe 3 are made into a cylindrical shape and are assembled together.
The upper end surface of the shower head 2 may be configured to be flush with the upper surface of the counter 15 at the lower end position.

【Effect of the invention】

As described above, the present invention includes a load detection unit that detects the load when the water supply pipe moves up and down, and a load detection unit that stops the water supply pipe after raising it when the load exceeds a predetermined value while the water supply pipe is lowering. The system is equipped with a control unit that controls the drive source, and if a load exceeding a predetermined value is applied from the outside while the water supply pipe is descending, the water supply pipe is stopped at the raised ridge, so foreign objects can be detected. Even if a foreign object or finger gets caught, the shower head immediately rises from that position and the foreign object or finger can be easily removed, which has the advantage of increasing safety.
