Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to the configuration of an auxiliary tank disposed in a low tank with a hand wash in a sanitary cleaning device such as a warm water flushing toilet of indirect water supply type.

Conventional configurations and their problems In general, when a flushing toilet with a low tank with a hand wash is combined with a sanitary cleaning device for private parts of the human body, bacteria etc. are present in the water stored in the low tank. The stored water cannot be used for washing water. Therefore,
Such devices require an auxiliary tank to store clean water.

A conventional device of this type is constructed, for example, as shown in FIG. That is, the auxiliary tank 2 is arranged in the low tank 1, the water diversion valve 4 is attached to the handwashing spout pipe 3, and the end of the connection hose 5 connected to the second discharge port is inserted into the auxiliary tank 2. There is. A submersible pump 6 is installed in the auxiliary tank 2, and a water supply hose 7 is connected to the discharge port of the submersible pump 6.
is in communication with a hot water tank (not shown) installed inside the private part cleaning device body 8 and a nozzle pipe 9. Note that 10 in the figure is a water supply pipe connected to the water supply, and communicates with the hand washing discharge pipe 3 through a ball tap (not shown).

In the above configuration, when the lever handle 11 is operated to supply water in the low tank 1 to the toilet bowl and flush the toilet bowl, water is supplied to the low tank 1 and the hand wash discharge pipe 3 by the ball tap, and the water is supplied to the water diversion valve 4.
The water for washing hands is discharged, and a portion of the water is supplied to the auxiliary tank 2 through the connection hose 5. When the auxiliary tank 2 overflows, it flows into the low tank 1, and the water level in the low tank 1 is maintained at its normal position by the constant water level means. Therefore, the water stored in the auxiliary tank 2 does not mix with the water stored in the low tank 1.

Next, when you perform the local cleaning operation, the submersible pump 6
is driven, and the water in the auxiliary tank 2 is pushed out to the nozzle pipe 9 through the water supply hose 7 and the hot water tank, and is used for local cleaning. In the waterway leading from the water supply pipe 10 to the auxiliary tank 2, the pole tap and the water diversion valve 4 have the function of a vacuum breaker, so that normally there is double safety against the backflow of the water stored in the auxiliary tank 2.

By the way, in this configuration, when the stored water in the auxiliary tank 2 is consumed, the water level decreases and creates buoyancy.
It is necessary to use a strong fixing method to prevent movement. Furthermore, since the amount of water held in the low tank 1 is reduced by the amount of water discharged from the auxiliary tank 2, it is necessary to make the low tank 1 larger.

Furthermore, since the water after hand washing flows into the low tank 1, an auxiliary tank 2 is used to prevent this from getting mixed in.
There are restrictions on the location and shape of the equipment.

Purpose of the invention This invention takes into account the above-mentioned drawbacks of the conventional technology, and doubles safety by making the auxiliary tank a backflow prevention structure, without creating buoyancy even when the water level of the auxiliary tank changes, and without being restricted by the shape and dimensions of the low tank. The purpose is to

Structure of the invention In order to achieve the above object, the present invention arranges an auxiliary tank outside the low tank, secures an effective spout space at the tip of the connection hose on the water supply side to the auxiliary tank, and prevents overflow. The structure is such that the water flows into the low tank.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the drawings.

In FIG. 2, 12 is a low tank, 12' is a lid of the low tank 12, 13 is a hand-washing discharge pipe whose discharge port is located on the lid 12', and 14 is a water diversion provided at the tip of the hand-washing discharge pipe 13. Valve 15 is a connection hose led out from the water diversion valve 14. Reference numeral 16 denotes an auxiliary tank, which is attached to the outside of the low tank 12 by means of a support fitting 17, and the connection hose 15 is connected to the upper part thereof. Said auxiliary tank 1
The overflow port 18 of No. 6 is opened on the lid 12' and forms an overflow surface. The spout 19 communicating with the connecting hose 15 has a space defined by regulations between the overflowing surface of the auxiliary tank 16 and the surrounding wall surface. A water supply hose 20 is connected to the low tank 16, and this water supply hose 20 communicates with a private part cleaning device (not shown). Note that 21 in the figure is a filter connected to the rear end of the water supply hose 20.

In the above configuration, water is supplied to the auxiliary tank 16 from the discharge port 19 each time the toilet bowl is flushed,
When the auxiliary tank 16 is full, water is drained from the overflow port 18 onto the lid 12' to maintain the overflow level.

If you operate the local cleaning device, the pump will operate,
Water is sent through the filter 21 and the water hose 20, and the water level in the auxiliary tank 16 is lowered. Air flows in and out of the upper space from the overflow port 18 as the water level changes, and atmospheric pressure is always maintained within the auxiliary tank 16.

Even if negative pressure is generated in the connecting hose 15, the overflow port 18 is open to the atmosphere and the discharge port 19 has the necessary discharge space, so that no backflow or contamination due to stored water will occur.

As described above, according to the embodiment of the present invention, even if the stored water increases or decreases, the auxiliary tank does not generate acting forces such as buoyancy that make the installation unstable, and does not affect the water volume of the low tank. The backflow and contamination prevention provided by the auxiliary tank alone, without the contamination of water after washing hands, has the added advantage.

Effect of invention According to the present invention, the following effects can be obtained.

(1) Even if the water level fluctuates, no force will be generated that will make the installation of the auxiliary tank unstable.

There is no need to increase the capacity of the low tank.

The auxiliary tank will not be contaminated with water after washing hands.

The auxiliary tank alone can satisfy legal regulations regarding backflow and contamination.

(2) Since the overflow port is opened at the top of the low tank lid, the low tank lid will not tilt and become unstable even without the use of height adjustment gaskets or special parts.
