A first embodiment of the present invention will be described below with reference to the drawings.
The first embodiment of the present invention shown in FIG. 1 to FIG. 3 relates to a drainage device attached to a sink (K) as drainage equipment as shown in FIG. The sink (S) which is the body, the drainage device with a trap function (1) attached to the sink (S), and the piping member (P) connecting the discharge port (10) of the drainage device (1) to the underfloor piping ) And the like.
The sink (K) includes a sink (S) that is a tank body having an opening on the bottom surface, and a cabinet (C) that houses and arranges each member including the drainage device (1) and the piping member (P) inside. Prepare.
The drainage device (1) has a function called a trap function, which has a function of accumulating wastewater inside and preventing odors and pests from entering the indoor side from the sewage side. It consists of a main body (6), a deodorizing jar part (7), and a garbage basket (not shown).
The drainage device body (6) has a bottomed cylindrical shape, and the upper opening functions as a drainage port (8) that collects drainage used by the drainage equipment, and the deodorizing cylinder (9) that rises upward from the bottom surface. And a discharge port (10) communicating with the deodorizing cylinder (9). The outer surface of the deodorizing cylinder (9) is covered with a metal layer (2) made of a stainless alloy having a thickness of about 0.3 millimeters. Moreover, the water sprinkling device (5) for extending | stretching a water film on the inner surface of a drainage device main body (6) is provided in the position above the upper end of the water surface of the sealing water mentioned later. Moreover, the transmission mechanism (4a) of the non-contact power supply (4) used as the power supply of an ultrasonic wave generation element (3) is provided in the outer surface of the drainage device main body (6).
The deodorizing gutter part (7) has a cylindrical shape with its upper end closed, and is embedded in the deodorizing gutter part (7), and the ultrasonic generator (3) for cleaning and a power source for the ultrasonic generator (3). A receiving mechanism (4b) of the contact power source (4) is provided. Further, the deodorizing ridge portion (7) is formed by coating the inner surface with a metal layer (2) made of a stainless alloy having a thickness of about 0.3 millimeters, and the end of the ultrasonic wave generating element (3) is formed on the metal layer (2). It is attached so that a part contacts. The other parts are formed of synthetic resin.
Here, the non-contact power source (4) described above is a power source connection structure configured by utilizing the theory of an insulating transformer, and is used for an electric toothbrush, a wireless telephone slave unit, and the like.
The structure will be briefly described. The transmission mechanism (4a) of the non-contact power source (4) provided with the primary side transformer and the receiving mechanism (4b) of the non-contact power source (4) provided with the secondary side transformer as well. Are placed in appropriate positions (there is no direct contact between them during this placement, hence the term non-contact). Here, when the magnetic flux is generated in the primary transformer by the high-frequency transmission circuit, the output-side two-shaped transformer receives the magnetic flux to generate electromagnetic induction. The current generated at this time is charged in a power storage function (generally a rechargeable battery) and used as a current for energizing the ultrasonic wave generating element (3).
The flow of electricity between the transmission mechanism (4a) and the reception mechanism (4b) is not a direct flow of electricity, but a flow that causes changes in power, magnetic force, and power. Even if it is not in direct contact, it can be transmitted through a wall or the like, so that electricity can be applied without opening a hole for wiring from the outside to the inside of the drainage device (1).
Most of the drainage device main body (6) and deodorization gutter part (7) of the drainage device (1) are formed of resin except for necessary parts such as the non-contact power source (4) and the metal layer (2). Being done.
The garbage basket is a member arranged inside the drainage device main body (6), and is composed of a bottomed cylindrical mesh body and a frame portion that suspends the mesh body to the periphery of the drainage port (8). It has the function of separating waste from the drainage by the body.

Each of the above members is connected to the sink (S) of the sink (K), which is a drainage device, as follows.
The drainage port (8) of the drainage device main body (6) is watertightly connected to the opening of the bottom of the sink (S), which is a tank body, and the discharge port (10) and the underfloor piping are further connected using a piping member (P). Connecting. Further, in the drainage device main body (6), the deodorizing gutter part (7) is placed at a position where the transmitting side and the receiving side of the non-contact power source (4) face each other properly and inside the deodorizing gutter part (7).

Further, the water supply pipe (W) is connected to the watering device (5) so that watering is possible when necessary, and the construction of the washing stand of this embodiment is completed.

  When the sink (K) configured as described above is used, the drainage that has flowed into the drainage port (8) from the sink (S) flows into the drainage device main body (6), and the deodorizing ridge part (7). It passes through the outer side surface, between the deodorizing jar part (7) and the bottom surface of the drainage device main body (6), between the deodorizing jar part (7) and the deodorizing cylinder (9), and finally the deodorizing cylinder (9). Drainage overflowing from the upper end is discharged from the discharge port (10) to the underfloor pipe through the pipe member (P). At this time, drainage accumulates as shown in FIGS. 2 and 3 between the bottom surface of the drainage device main body (6) and the upper end of the deodorizing cylinder (9) (WL in FIGS. 2 and 3 is This is the surface of the sealed water). This accumulated drainage is called sealed water, and odors and pests that have flowed back from the underfloor piping side cannot pass through this sealed portion, so odors and pests can be passed indoors through the drainage port (8). No longer intrudes. In addition, most of the dust mixed in the drainage is collected in the garbage can placed in the drain outlet (8), and does not flow out to the downstream side of the waste bin (the eye of the garbage can). A small part, such as smaller trash, will flow downstream from the trash.)

In the drainage device configured as described above, when dust or slime is generated in the drainage device (1) due to the use of the sink (K), depending on the generation and adhesion of dust and slime on the inner surface of the drainage device body (6), The following two methods can be selected for cleaning.
(1). In particular, when dust or slime is concentrated on the portion in contact with the sealed water, only the ultrasonic wave generating element (3) is operated. Specifically, when power is supplied to the transmission mechanism (4a), magnetic flux is generated by the primary transformer and the primary transformer of the transmission mechanism (4a), and current is generated by electromagnetic induction of the secondary transformer of the reception mechanism (4b). Through the process, current finally flows through the ultrasonic wave generating element (3), and ultrasonic waves for cleaning are generated. The ultrasonic wave generated by the ultrasonic wave generation element (3) vibrates the metal layer (2) of the deodorizing gutter part (7) in contact with the ultrasonic wave and transmits the ultrasonic vibrations throughout the sealed water (cleaning ultrasonic wave). Vibrations in the liquid). Particularly in this embodiment, as shown in FIG. 2, the metal layer (2) is disposed not only on the inner surface of the deodorizing ridge part (7) but also on the deodorizing cylinder that is opposed to the inner surface of the deodorizing ridge part (7) that is an ultrasonic generation source. Since it is also provided on the outer surface of (9), reflection of ultrasonic waves occurs in the metal layer (2) on the outer surface of the deodorizing cylinder (9), and the ultrasonic waves are efficiently transmitted to the entire inside of the sealed water. .
As a result, fine bubbles are generated inside the drainage device main body (6) and the surface of the portion of the deodorizing jar portion (7) that is in contact with the sealed water, and this foam is sealed inside the drainage device main body (6). Decomposes and peels off dust and slime adhering to the surface of the part in contact with the surface and the deodorizing gutter part (7), and drops and settles it in the sealed water.

In this manner, the ultrasonic wave generating element (3) is operated in a state where the water film from the watering device (5) is stretched on the inner surface of the trap body (6). Specifically, when power is supplied to the transmission mechanism (4a), magnetic flux is generated by the primary transformer and the primary transformer of the transmission mechanism (4a), and current is generated by electromagnetic induction of the secondary transformer of the reception mechanism (4b). Through the process, current finally flows through the ultrasonic wave generating element (3), and ultrasonic waves for cleaning are generated. The ultrasonic wave generated by the ultrasonic wave generation element (3) vibrates the metal layer (2) of the deodorizing gutter part (7) in contact with the ultrasonic wave and transmits the ultrasonic vibrations throughout the sealed water (cleaning ultrasonic wave). Oscillates in the continuous liquid). In particular, in this embodiment, the metal layer (2) is placed not only on the inner surface of the deodorizing jar part (7) but also on the outer surface of the deodorizing cylinder (9) which is the position opposite to the inner surface of the deodorizing jar part (7) which is an ultrasonic generation source. Therefore, the reflection of ultrasonic waves is generated in the metal layer (2) on the outer surface of the deodorizing cylinder (9), and the entire portion of the drainage device (1) that is in contact with water is efficiently exceeded. Sound waves are transmitted.
In this way, in addition to the surface of the drainage device main body (6) and the deodorizing gutter part (7) in contact with the sealed water, the drainage device main body (6) with a water film stretched by the water sprayed from the water spraying device (5) Fine bubbles are also generated on the inner surface, and the bubbles decompose and peel off dust and slime adhering to the inner surface of the drainage device main body (6) and the surface of the deodorizing gutter (7) and drop them into the sealed water.
Furthermore, the water flow from the water sprinkling device (5) generates a flow of waste water in the drainage device main body (6). Dust and sludge falling into the sealed water are directly discharged along the flow of the drainage ( 10) is discharged to the sewage side through the piping member (P).
Further, in this first embodiment, since the ultrasonic generating element is provided in the detachable deodorizing gutter part, when a failure occurs in the ultrasonic generating element etc., only the deodorizing gutter part is removed and mailed to a supplier. The member can be easily repaired.
