Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a water supply tank for a warm water flush toilet seat used in a Western-style toilet.

[Prior art]

Warm water washing toilet seats are equipped with the function of washing the buttocks.Using this type of toilet seat not only allows you to keep your buttocks clean at all times, but also has the pine surge effect of warm water, which promotes natural passage. In recent years, it has attracted attention as a health device and has become widely used, as it has the advantage of providing health benefits.

As shown in a schematic diagram in FIG. 1, this hot water flush toilet seat includes a main body 2 disposed on a toilet bowl 1 installed on the floor of the toilet, and a toilet seat 3. Inside the main body 2, a hot water tank 4 for heating and storing water, a pump 6 for supplying water to the hot water tank 4 via a hose 5, etc. are built in. A cleaning nozzle 8 introduced from the hose 7 and ejecting water is provided so as to be movable forward and backward so as to face approximately the center of the toilet seat 3. That is, these hot water tank 4, pump 6,
The cleaning nozzle 8 constitutes a cleaning device that cleans the anal region of a person 10 sitting on the toilet seat 3 with a fountain 9 ejected from the cleaning nozzle 8.

Reference numeral 11 denotes a warm water flush toilet seat water supply tank for supplying water to the warm water flush toilet seat, the bottom of which is connected to the suction side of a pump 6 built into the main body 2 through a hose 12.
Further, a hose 16 connected to a branch fitting 15 attached to the tip of a hand-washing faucet 14 connected to a water source via a valve 13 is connected to the top, and water is supplied from the water source.

The hose 12 is a water supply tank 1 for a warm water-washing toilet seat.
As shown in an enlarged view of the bottom part A of FIG. Also,
A filter 19 formed in a cylindrical shape with a bottom is provided at the bottom of the water supply tank 11 for a warm water flushing toilet seat so as to be inserted into the connection hole 17 . A filter portion 19a is formed over the entire filter 19, and a flange portion protruding in the radial direction from the opening edge is fixed by being pinched by the connection fitting 18. The filter portion 19a is formed in a fine mesh shape of, for example, 250 mesh in order to filter out foreign matter 20 such as dust and limescale in the water supply tank 11 for a warm water-washing toilet seat.

Then, the water in the water supply tank 11 for the warm water flushing toilet seat is introduced into the warm water flushing toilet seat using the pump 6, and
It is configured to jet hot water heated in a hot water tank 4 from a cleaning nozzle 8 to clean the anal region.

However, the conventional water supply tank for a warm water flushing toilet seat used in this type of warm water flushing toilet seat has the disadvantage that it cannot necessarily prevent the warm water flushing toilet seat from clogging with dirt. This is because the foreign matter 20 such as fine dust and limescale deposited on the inner bottom of the water supply tank 11 for the warm water-washing toilet seat is always facing the filter section 19a, and there is a risk that it may pass through the filter section 19a. This results in foreign matter 20 such as fine dust and water scale clogging the small diameter spout of the cleaning nozzle 8.

[Summary of the idea]

The present invention was devised in view of these circumstances, and has an extremely simple structure in which a filter part that communicates between the inside of the tank and the inside of the pump is provided in a part of the filter provided at the bottom of the tank that is upwardly away from the bottom of the tank. This provides a water supply tank for a warm water flush toilet seat that can prevent the warm water flush toilet seat from being clogged with dirt. Hereinafter, its configuration and the like will be explained in detail with reference to embodiments shown in the drawings.

[Example of idea]

FIG. 3 is an enlarged sectional view showing the bottom of the water supply tank for a warm water bidet toilet seat according to the present invention. In the figure, the part indicated by the reference numeral 21 is the main part of the present invention, and is provided in the water supply tank 11 for a warm water bidet toilet seat. Shows the filter that was created. This filter 21 is formed from a resin material such as plastic into a cylindrical shape with a bottom, as in the conventional filter, and has a flange portion protruding in the radial direction from the opening edge. Then, this flange portion is screwed into a threaded portion 11a that is integrally provided in correspondence with the connection hole 17 of the water supply tank 11 for a hot water bidet toilet seat, and is compressed by a connection fitting 18 that connects the hose 12. , the filter 21 is inserted into the connection hole 17 and fixed.

Reference numeral 21a denotes a filter portion that communicates the inside of the water supply tank 11 for the warm water-washing toilet seat with the inside of the pump 6 of the warm-water washing toilet seat.This filter portion 21a is different from the conventional one in that it is a part upwardly separated from the tank bottom surface 11b; It is provided above the height L from the tank bottom surface 11b, and is formed into a fine mesh shape of, for example, 250 mesh in order to filter out foreign matter 20 such as dust and water scale. The height L is the tank bottom 1
The height is set to an arbitrary height that is higher than the foreign matter 20 such as dust and water scale deposited on the surface 1b. In other words, the portion of the filter 21 that is lower than the height L from the tank bottom surface 11b is formed into an airtight wall shape that shields the inside and the outside.

In the warm water flushing toilet seat water supply tank configured in this way, the water filtered by the filter portion 21a can be supplied to the warm water flushing toilet seat pump 6 that cleans the anal region after defecation.

Here, since the filter portion 21a of the filter 21 is spaced above the tank bottom surface 11b, water in a portion whose height from the tank bottom surface 11b is higher than the height L is allowed to pass into the filter 21.
For this reason, water near the tank bottom 11b where foreign matter 20 such as dust and limescale has accumulated is removed from the filter 21.
This prevents foreign matter 20 such as accumulated dirt and water scale from being sucked into the pump 6. In other words, since the filter portion 21a through which water passes is provided at a higher position than the foreign matter 20 such as accumulated dirt and water scale, even if the pump 6 is operated and water is sucked in, the tank bottom surface 11b
The deposits are not sucked in.

[Effect of idea]

As explained above, according to the present invention, a filter part that communicates the inside of the tank and the inside of the pump of the hot water bidet toilet seat is provided in a portion of the filter provided in the tank connected to the hot water bidet toilet seat, and is located upwardly away from the bottom of the tank. This allows water above the deposits to pass through the filter and prevents foreign matter such as dust and limescale from being sucked into the pump of the warm water-washing toilet seat.

Therefore, foreign matter such as dirt does not flow into the water circuit system of the hot-water-washing toilet seat, which prevents the cleaning nozzle outlet from clogging and allows for safe use.
