Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier for obtaining raw water such as tap water through a water purifying mechanism including a filtering member such as a ceramic filter or a hollow fiber filter and an adsorbing member such as activated carbon. The present invention relates to a stationary water purifier having a water pipe.

[0002]

2. Description of the Related Art Water purifiers currently on the market are roughly classified into a type in which a water purifying mechanism is attached to a faucet of a water supply and a stationary type in which the water purifier is placed at a position apart from the faucet.

A water purifier of the type attached to a tap is
Since the water purifier main body having a cartridge with a built-in water purification mechanism and a switching cock for switching between tapping straight tap water and discharging tap water is directly attached to the tap, Due to the strength and convenience of handling, the size of the cartridge containing the water purification mechanism is limited, so the water purification capacity is small and it is used exclusively for home use.

On the other hand, in the stationary type, although it is necessary to provide a switching cock for switching between the case where the raw water of the tap is fed straight and the case where the purified water is obtained, the main body of the water purifier is installed. Since it is possible to appropriately increase the water purification capacity by making it large, it is used for households and businesses that use a large amount of water.

In this stationary water purifier,
There is one that returns the obtained purified water to the tap of the tap and discharges the purified water in this part, and another that attaches the discharge pipe to the water purifier itself and discharges the purified water from the discharge pipe. It exists and is used by appropriately selecting it according to the preference of the user.

In particular, in the latter type of stationary water purifier having a water discharge pipe, since the water purifier itself is large and heavy, it cannot be easily moved. Therefore, in order to change the supply direction of the purified water, the water discharge pipe itself is rotated horizontally. It was made movable.
For example, the one described in JP-A No. 11-47731 is an example. The known stationary water purifier will be described below with reference to FIGS. 6 and 7.

The known stationary water purifier 100 includes a flow path switching device 104 directly connected to a faucet 102 such as a water supply.
A water purifier body 106 for purifying raw water, and a hose 10 for communicating the flow path switching device and the water purifier body to lead the raw water to the water purifier body.
8, the flow path switch 104 has its raw water inlet connected to the faucet 102 via a nut 110.

The flow path switch 104 has a raw water outlet at the lower end and a water supply port at the rear end, and the hose 1 is connected to this water supply port.
08 is connected, and a flow passage switching valve (not shown) is housed inside the flow passage switching device 104, and the lever 112 provided on the side portion of the flow passage switching device 104 operates the flow passage switching valve. The raw water from the faucet 102 can be switched between a state where it is discharged from the raw water outlet as it is and a state where it is guided to the water purifier body 106 through a hose 108.

The water purifier body 106, as shown in FIG.
A bottomed cylindrical outer frame 114 and a filter unit 116
The outer frame 114 has an upper end that is opened and a disc-shaped bottom plate 122 that is fixed to the lower end. And, L having a running water channel at the center of the lower end
One end of the water injection nozzle 124 is attached to the opening 126 formed at the bottom of the outer frame 114 in a watertight state, and is rotatably supported by the bottom plate 122. A hose 108 is communicatively connected to the obtained water inlet 128.

A filter unit 116 is attached to the lower end of the upper lid 118 via a filter support plate 130, and is detachably attached to the outer frame 114. The filter support plate 130 is provided with an L-shaped water outlet 132 that is led out from the center of the upper end in the radial direction,
A short cylindrical protrusion 134 opened at the center of the lower end is provided,
The upper end water outlet 136 of the filter unit 116 is detachably connected to the inner peripheral surface of the convex portion 134. Also,
The lower end water inlet 138 of the filter unit 116 is detachably connected to the outer peripheral surface of the water inlet nozzle 124.

Furthermore, an L-shaped connecting nozzle 1 having a water purification channel
One end of 40 is projected upward from a semicircular opening 142 formed on the outer peripheral surface of the upper portion of the upper lid 118, and the other end of this connecting nozzle 140 is the water outlet 1 of the filter support plate.
A part of the connecting nozzle 140 that is connected to 32 and that projects from the opening 142 bulges to the inner surface of the upper lid, and the remaining part bulges to the outer surface of the upper lid.

The base end of the L-shaped water discharge pipe 120 is
It is connected to the outlet end of the connecting nozzle 140, is rotatably supported on the central axis a of the connecting nozzle, and the tip of the water discharge pipe 120 is bent downward.

[0013]

Therefore, in this known water purifier main body 106, the water supply position of the purified water is determined by the water supply pipe 1.
At the height where the tip of 20 is located, it can be widely changed within a predetermined angle range within a horizontal plane centered on the axis a, but since the water discharge pipe 120 cannot rotate in the vertical direction, When supplying purified water into a container with a high height, it may be difficult to supply purified water. Conversely, when supplying purified water into a container with a low height, put the container on the floor and splash water around it. Therefore, it is necessary to support the container by hand at all times, and when the water discharge pipe 120 is rotated while the supply of purified water is stopped, the purified water remaining in the water discharge pipe is discharged. There is a problem that it may drip from the tip, and the surroundings may be flooded.

As a result of various experiments conducted by the inventors to solve the problems of the water purifier body of the conventional example, if the structure in which the water discharge pipe itself is rotated in the vertical direction is adopted, the purified water is supplied. We found that there is no risk of water dripping even if the water discharge pipe is moved while it is stopped, but when the water discharge pipe itself is rotated not only vertically but also to the left and right, the rotation mechanism The structure is so-called multi-joint structure, and the structure is complicated, so that there is a great risk that water leakage will occur at that part, and it is difficult to stop and fix the tip of the discharge pipe at a desired position. .

In the tabletop thermos bottle, the tabletop electric pot, etc., the structure is known in which the hot water supply nozzle is freely rotated in the horizontal direction by 360 degrees by making the main body rotatable, but these structures are known. , If nothing is connected to the outside, or if something connected to the outside is flexible like an electric cord, it can be applied because the electric cord can follow the movement of the electric pot. However, when applied to a stationary water purifier of the present invention having a rigid water supply hose attached to the water purifier body, the water supply hose also moves in accordance with the horizontal rotation of the water purifier body. It could not be applied as it is, because it may come into contact with surrounding articles or the rotation of the water purifier body may return to its original position due to the rigidity of the water supply hose.

[0016]

As a result of various experiments conducted by the inventors, the horizontal rotation range actually required for a stationary water purifier is adopted in a well-known tabletop thermos bottle or electric pot. Since a very narrow range is sufficient compared to the rotating range, the main body of the water purifier is within a predetermined angle range in the horizontal direction without moving the water supply hose, which has never been used in a stationary water purifier. If the structure that can be rotated by is adopted, the position of the discharge pipe can be easily moved vertically and horizontally by adopting the structure that the discharge pipe itself can be rotated only in the vertical direction. Further, they have found that they can be fixed at desired positions, and have completed the present invention.

That is, according to the present invention, in a stationary water purifier to which a rigid water supply hose is attached, the position of the water discharge pipe can be moved not only horizontally but also vertically without moving the water supply hose. Moreover, it is an object of the present invention to provide a stationary water purifier that has a simple structure and is less likely to leak water.

The above object of the present invention can be achieved by adopting the following constitution.

That is, in one embodiment of the present invention, the supplied raw water is guided to the water purifier body for purification, and the purified water is discharged from a water discharge pipe attached to the water purifier body.

Te predetermined angle pivotally mounted, and the body cover is stationary water purifier that are removably attached to said upper base member is provided. According to this aspect, the rotation mechanism is simplified, and the upper base member and the main body cover can be horizontally rotated while the lower base member is fixed, so that the raw water of the lower base member can be rotated. The water supply hose connected to the supply port does not move, water drops that occur when the water discharge pipe is rotated in the horizontal direction do not occur, and the cartridge assembly can be easily replaced.

At this time, the upper water outlet of the cartridge assembly is watertightly fitted to one end of a cylindrical member fixed to the body cover, and the other end of the cylindrical member is connected to the water discharge pipe, and the cartridge is also attached. When the lower end water inlet of the assembly is watertightly rotatably fitted to the water inlet nozzle of the lower base member, the outside of the cartridge assembly is fixed to the upper base member, and the main body cover is rotated, the cartridge assembly is inserted. The solid may also be adapted to rotate, or
The upper end outlet of the cartridge assembly is watertightly rotatably fitted into one end of a cylindrical member fixed to the main body cover, and the other end of the cylindrical member is connected to the water discharge pipe,
Further, even if the lower end water inlet of the cartridge assembly is watertightly fitted to the water inlet nozzle of the lower base member, the outside of the cartridge assembly is fixed to the lower base member, and the main body cover is rotated, The cartridge assembly may be non-rotatable.

According to another aspect of the present invention, a plurality of protrusions are provided in the circumferential direction in the vicinity of the lower end of the main body cover, and two protrusions are provided inward, and the protrusions are provided at predetermined positions on the upper base member. After fitting the plurality of protrusions of the cover into the plurality of cutouts, respectively, the main body cover is rotated together with the upper base member to a rotation end point, and the upper portion of the main body cover above the protrusions is rotated. There is provided a stationary water purifier in which the main body cover is prevented from coming off from the upper base member by locking the portion with a large diameter portion provided on the upper base member. With such a configuration, the main body cover can be easily attached to and removed from the upper base member.

According to still another aspect of the present invention, the upper base member is provided with at least one locking projection on its outer periphery, and is provided at each of the plurality of positions by further rotating the body cover. There is provided a stationary water purifier in which one of the two projected portions is passed over the locking convex portion and the locking convex portion is located between the two projected portions. It According to this aspect, the main body cover and the upper base member are firmly coupled to each other, and both can rotate integrally during use.

Further, according to another aspect of the present invention, at least a pair of vertically extending ribs are provided on the outer surface of the cartridge assembly, and two protrusions provided inside the main body cover are provided. It is desirable that the portion be slidable between the pair of ribs so as to serve as a guide when the body cover is attached. With this configuration, the cartridge cover can be smoothly attached when the main body cover is attached after the cartridge assembly is attached.

Further, in the present invention, it is preferable that the water discharge pipe has a ratchet mechanism for locking and fixing at a predetermined interval over a predetermined angle. According to this aspect, since the water discharge pipe is firmly fixed to the predetermined position to some extent, there is no fear of turning due to the discharge pressure of the purified water. Further, in the present invention, it is desirable to attach an L-shaped nipple to the raw water supply port of the lower base member so as to be vertically rotatable. By doing so, it is possible to easily route the rigid water supply hose.
