Description

The present invention relates to a watering device and a watering method capable of sprinkling water by a plurality of spouting modes including a fan-shaped spouting region having a fan-shaped spouting region.

Conventionally, a multifunctional watering device having an additional water discharge function capable of discharging not only shower water but also straight water has been known. For example, Patent Document 1 discloses a multifunctional watering device that can be used by switching between a hard shower, a soft shower, and a massage shower having different water discharge amounts and water pressures. According to the watering apparatus of Patent Document 1, shower water having a different diffusion range and strength can be used.

Japanese Unexamined Patent Publication No. 2005-131143

When a certain part or place is roughly washed away, the washing work can be performed with shower water. On the other hand, for example, when cleaning the inside of a bathroom, the outer wall of a house, a vehicle or building equipment such as a sash, depending on the cleaning location, for example, a relatively wide wall surface or, for example, a tile joint of a bathroom, a rail of a sash, etc. It involves cleaning work to remove dirt from relatively narrow areas such as gaps.

However, as in Patent Document 1, even if the diffusion range of the shower water is switched, the shower water is limited to the cleaning application by spraying a water stream, so that the relatively wide wall surface and the relatively narrow portion as described above can be used. Cleaning that involves removing dirt has the problem that shower water is an inefficient cleaning operation. For cleaning a relatively wide wall surface and a relatively narrow part, a watering method can be used in which the watering hole of the watering head of the watering device is grooved to sprinkle fan-shaped water. The fan-shaped spout can be washed like a brush by moving the water flow ejected into the fan-shaped spouting area from side to side and up and down, so it is suitable for cleaning a wide cleaning surface, and along a narrow groove. By pouring the water stream, water can be sprinkled intensively and cleaning of narrow cleaning grooves can be performed.

However, when the watering device is provided with the additional function of the fan-shaped watering nozzle, there is a problem that the range of use is limited if the orientation of the fan-shaped watering nozzle is fixed. That is, even if a groove hole for generating fan-shaped water is formed in the water discharge head, the direction of the water discharge area is fixed. Therefore, for example, when switching from vertical cleaning to horizontal cleaning of the cleaning location, the direction of the water discharge area is changed. If you try to switch from a vertical fan shape to a horizontal fan shape, the range in which you can turn your wrist from the state where you once grasped the sprinkler is limited, so the direction of the fan-shaped water discharge area is greatly changed to a vertical fan shape or a horizontal fan shape just by tilting the water discharge head. There was a problem that it was difficult to operate and the operability was reduced.
