Description

  The present invention relates to a sink drainage mechanism for draining used water in a sink, such as a sink for washing various articles and human limbs.
  In recent years, attention has been paid to the function of electrolytically generated water (electrolyzed alkaline water, electrolytically generated acidic water) generated by diaphragm membrane electrolysis using a dilute aqueous solution in which a small amount of electrolyte such as salt is dissolved as electrolyzed water, For these electrolyzed water, electrolyzed alkaline water is used as washing water to wash away contaminants adhering to various articles and human limbs, and electrolyzed acidic water is adhered to various articles and human limbs. There are uses that are used for sterilizing water that kills and flushes various bacteria.
For use in such applications the electrolyzed water, and pouring into the sink led electrolyzed water produced by the electrolytic water generation apparatus above the site of the sink or the like sinks, the spent electrolyte produced water A means for draining through a drainage mechanism provided in the sink is employed (see Patent Document 1).
  In the sink, of course, when various articles and human limbs are sterilized and washed, electrolytically generated acidic water is used. Electrolyzed acidic water having a strong bactericidal ability is strongly acidic with a pH of 3.0 or less, and residual chlorine tends to volatilize, and is highly corrosive to metals. For this reason, even in used electrolytically generated acidic water, strong corrosiveness is maintained, and in particular, strong corrosiveness is exhibited at the gas-liquid interface of electrolytically generated acidic water.
  In a normal sink, a drainage mechanism with a drain pipe connected to a drain outlet provided at the bottom of the sink and leading to a drainage groove and a trap located in the middle of the drain pipe in order to drain used water It has. In the sink having the drainage mechanism, the used electrolytically generated acidic water stays in the U-shaped reservoir of the drainage mechanism during drainage. For this reason, corrosive chlorine is volatilized from the electrolytically generated acidic water staying in the reservoir, and the volatilized chlorine is converted into chlorine gas to the drain pipe section upstream of the trap constituting the drain mechanism and downstream of the trap. It diffuses into the drainage pipe section on the side and becomes a factor that corrodes the upstream and downstream sites of the trap in the drainage mechanism.
In order to eliminate such a factor, when draining used electrolytically generated acidic water or prior to draining, a means for neutralizing using a neutralizing agent is effective. The proposed sink employs a neutralizer containing a neutralizer instead of the conventional trap. The neutralizer is provided with a neutralizer tank disposed above the tank body and facing the lower end opening of the drain pipe extending straight from the bottom of the sink, and the neutralizer tank contains the neutralizer. In the state, it opens to the lower end opening side of the drain pipe. In the sink, used electrolytically generated acidic water is introduced into the inside of the neutralization tank through the drainage pipe from the drainage port at the bottom of the sink and into the inside of the neutralization tank. It is summed, led out to the tank body, and drained to the outside.
  On the other hand, in the large-sized water heater, which is a special type of heat source machine that has a completely different configuration, function, and application and has a completely different technical field, the acid drain water generated in the water heater is not used. The example which has taken the means to neutralize with a neutralizer can be recognized (refer patent document 2).
The water heater is a large-sized water heater of a special type of a latent heat recovery type that recovers latent heat, and has a problem that when the latent heat is recovered, combustion exhaust gas is condensed and acidic drain water is generated. . Therefore, in the water heater, it is necessary to neutralize and drain the drain water, and a neutralizer filled with a neutralizing agent is employed. The neutralizer is formed by filling a U-shaped filling space formed in a synthetic resin container body with a neutralizing agent, and is disposed on the front side of the water heater body. used. In the neutralizer, the acidic drain water generated when recovering the latent heat of the water heater is introduced into the neutralizer, the permeated neutralizer is permeated, and the neutralizer is externally introduced. It is designed to be discharged to drain.
Japanese Patent Laid-Open No. 10-480 JP 2001-241648 A
By the way, in the drainage mechanism equipped with the neutralization device proposed in Patent Document 1 described above, the used electrolytically generated acidic water is directly introduced into the neutralizer tank from the drainage pipe that directly extends, and the neutralizer The inside of the neutralizing agent accommodated in the tank is instantaneously permeated to be led out into the tank body and drained to the outside. For this reason, the time for the electrolytically generated acidic water to contact the neutralizing agent is extremely short, and the electrolytically generated acidic water may not be sufficiently neutralized. In addition, the drainage mechanism does not have a trap function because there is no trap in the middle of the drainage pipe or between the drainage pipe and the neutralizer tank, and volatilizes from the electrolyzed acidic water before reaching the neutralizer tank. Odor generated from chlorine gas and other drainage channels cannot be blocked.
  On the other hand, the neutralizer proposed in Patent Document 2 described above is for neutralizing special acidic water called acidic drain generated in the latent heat recovery step in a large water heater, It has a unique structure inside and is filled with a neutralizing agent. Therefore, in order to apply the neutralizer to the sink drainage mechanism, it is necessary to change the neutralizer to a structure and shape that can be suitably applied to the sink drainage mechanism, and from the drainage mechanism side. Then, it is necessary to change the structure and shape of the drainage mechanism itself so that the neutralizer can be applied. Furthermore, in the drainage mechanism that has been enlarged by adding a neutralizer, it is necessary to consider the disposition position in the lower part, which is a limited space of the sink. For this reason, in order to apply to the drainage mechanism of the neutralizer, these problems must be solved, and also the cost problem of the drainage mechanism must be solved.
  The present invention addresses the above-mentioned many problems, and the main object of the present invention is to use the conventional sink drainage mechanism itself for draining used water in a sink that uses electrolytically generated water as the used water. The purpose is to provide a function of neutralizing the electrolytically generated acidic water.
The present invention relates to a sink drainage mechanism, and more particularly, to a sink drainage mechanism for draining used water in a sink that uses electrolytically generated water as use water. In the drainage mechanism according to the present invention, acid-generated acidic water is contained in the reservoir of an acid-resistant U-shaped trap that is connected to the drainage port of the sink and is disposed in the middle of the drainage pipe that reaches the drainage groove. It is a drainage mechanism for a sink in which a neutralizing agent for harming is stored .
Thus, in the sink drainage mechanism according to the present invention, the trap is provided with a U-shaped reservoir and an upstream drain pipe provided at an upper end on the upstream side of the reservoir and extending from the bottom of the sink. A first connecting pipe connected to the upper end of the reservoir, and a second connecting pipe connected to a downstream drain pipe provided at the upper end of the reservoir. A supply port for charging the neutralizing agent into the bottom of the reservoir is formed, and the supply port is configured to be openable and closable by a lid.
  Further, the trap according to the present invention can be formed of an acid-resistant synthetic resin, and in this case, the entire trap or at least a reservoir of the trap is formed of a transparent synthetic resin. Is preferred.
  The sink provided with the sink drainer may use only electrolytically generated acidic water, and selectively use both electrolytically generated alkaline water and electrolytically generated acidic water. It may be used.
  The sink drainage mechanism according to the present invention includes a drain pipe connected to the drain outlet of the sink to reach the drain groove, and a trap interposed in the middle of the drain pipe. The basic configuration is that a neutralizing agent for neutralizing the electrolytically generated acidic water is accommodated.
  According to the sink drainage mechanism, the electrolytically generated acidic water used in the sink is introduced into the trap from the drain outlet at the bottom of the sink through the upstream drain pipe and is stored in the trap reservoir. It passes through the sump and is led to a downstream drain pipe connected to the trap for drainage. During this time, the electrolytically generated acidic water once stays in the trap reservoir and comes into sufficient contact with the neutralizing agent contained in the reservoir. For this reason, the electrolytically generated acidic water is sufficiently neutralized in the trap and drained through the downstream drainage pipe.
  As described above, the sink drainage mechanism effectively uses the trap of the conventional sink discharge mechanism, and has the function of neutralizing the electrolytically generated acidic water used in the trap. For this reason, the sink drainage mechanism has a trap function, so that the problem occurring in the neutralization device due to the absence of the trap is solved, as well as the sink drainage as described above. Various problems for incorporating the neutralizing device constructed separately from the mechanism into the drainage mechanism instead of the trap do not occur, and there is no major problem in terms of cost. Specifically, the sink drainage mechanism can have a simple configuration as shown below, and adopting such a configuration is advantageous in terms of cost.
  That is, the trap constituting the sink drainage mechanism is connected to a U-shaped reservoir and an upstream drainage pipe provided on the upstream upper end of the reservoir and extending from the bottom of the sink. A first connecting pipe and a second connecting pipe provided at the upper end on the downstream side of the reservoir and connected to the drain pipe on the downstream; and a neutralizer is added to the upper end of the reservoir. A supply port for feeding into the bottom of the reservoir is provided, and the supply port can be opened and closed with a lid. In this case, the trap is preferably formed of an acid-resistant synthetic resin, and the entire trap or at least the reservoir of the trap is preferably formed of a transparent synthetic resin. According to this configuration, the consumption of the neutralizing agent accommodated in the trap reservoir can be visually recognized from the outside, and the timing of replenishment of the neutralizing agent can be accurately confirmed.
  The sink equipped with the sink drainer may use only electrolytically generated acidic water, or selectively use both electrolytically generated alkaline water and electrolytically generated acidic water. Of course, it may be used.
  The present invention relates to a sink drainage mechanism for draining used water in a sink using electrolytically generated water as used water. A drainage mechanism according to the present invention is a structure including a drain pipe connected to a drain outlet of a sink and reaching a drain groove, and a trap interposed in the middle of the drain pipe. And a neutralizing agent for neutralizing the electrolytically generated acidic water.
FIG. 1 schematically shows a sink equipped with a drainage mechanism according to an embodiment of the present invention, and an electrolyzed water generator for supplying electrolyzed water to the sink. FIG. 2 shows the drainage mechanism. The electrolyzed water generating device 10a is a well-known electrolyzed water generating device of the diaphragm membrane electrolysis type mainly composed of a diaphragm electrolyzer, and is installed in the vicinity of the sink 10b. The electrolyzed water generating device 10a uses each electrolyzed water (electrolyzed acidic water and electrolyzed alkaline water) generated in each electrolysis chamber of the diaphragm electrolyzer to each pouring pipe 11 (only one pouring pipe). Through the sink 10b. Selection of each electrolytically generated water is selected by opening and closing each extraction valve 12 (only one extraction valve is shown).
  The sink 10b installed in the vicinity of the electrolyzed water generating apparatus 10a is equipped with a drainage mechanism 20 according to an embodiment of the present invention, and each used electrolyzed water used in the sink 10b is the drainage mechanism. 20 is led out to the drainage groove 10c, and drained from the drainage groove 10c to the predetermined external location through the final drainage pipe 10d.
  As shown in FIG. 2, the drainage mechanism 20 includes a first drain pipe 20a that is an upstream drain pipe connected to a drain port provided at the bottom of the sink 10b, and a drain groove 10c provided below the floor. The second drain pipe 20b, which is a drain pipe on the downstream side facing the, and a trap 20c that connects the first drain pipe 20a and the second drain pipe 20b to each other.
  The trap 20c includes a U-shaped reservoir 21, a first connection pipe 22 that is located at the upstream end of the reservoir 21 and connects the upstream of the trap 20c to the first drain pipe 20a, and a reservoir. 21 is provided with a second connecting pipe portion 23 that is located at the downstream end of 21 and connects the downstream side of the trap 20c to the second drain pipe 20b. A supply hole 24 is provided for feeding into the container. An upper end opening of the supply hole 24 is formed in a neutralizer charging port 24 a, and the charging port 24 a is configured to be opened and closed by a lid 25. The lid body 25 is formed in a plug state so that it can be fitted into the insertion port 24a, and the insertion port 24a is closed and fitted by fitting the lid body 25 into the insertion port 24a as a plug. By removing the lid 25 from the insertion port 24a, the insertion port 24a is opened.
  The trap 20c is assembled by assembling a plurality of transparent molded members formed of acid-resistant synthetic resin such as polyvinyl chloride. The forming member constituting the trap 20c is a straight cylindrical body and a curved cylindrical body, and forms a U-shaped reservoir forming member 21a that forms the reservoir 21, and a first connecting pipe portion 22. The first pipe part forming member 22a, the second pipe part forming member 23a forming the second connecting pipe part 23, and the supply hole forming member 24b forming the supply hole part 24.
  The trap 20c has a reservoir forming member 21a as a main body and is assembled by fitting each molding member to the reservoir forming member 21a. A first pipe portion is formed at each upper end opening of the reservoir forming member 21a. The member 22a and the supply hole forming member 24a are fitted, and the second pipe forming member 23a is fitted to the side opening of the supply hole forming member 24a.
  In the trap 20c, the first tube forming member 22a extends straight upward to form the first connecting tube portion 22, and the second tube forming member 23a extends horizontally and extends to the second connecting tube portion 23. Further, the upper end of the supply hole forming member 24b is opened upward, and the opening forms the insertion port 24a. The first drain pipe 20a connected to the drain port provided at the bottom of the sink 10b is fitted into the upper end opening of the first pipe section forming member 22a and faces the drain groove 10c. 20b is fitted into the tip opening of the second tube forming member 23a. In addition, the charging port 24 a of the supply hole forming member 24 b is closed by fitting a lid body 25 after charging a predetermined amount of neutralizing agent into the bottom of the reservoir 21. The neutralizing agent is, for example, a neutralizing agent mainly composed of calcium carbonate such as cold water stone, and the charged neutralizing agent can be visually recognized through the reservoir forming member 21a from the outside.
  In the sink 10b equipped with the drainage mechanism 20 having such a configuration, the electrolytically generated alkaline water is poured out from the electrolyzed water generating device 10a in the cleaning for cleaning various articles, limbs, and the like to which contaminants are attached. Wash using as cleaning water. Moreover, in the sterilization washing | cleaning which sterilizes the various substances, limbs, etc. to which various bacteria adhere, electrolytically produced acidic water is poured out from the electrolyzed water generation apparatus 10a, and this is used as sterilization washing water for sterilization washing.
  In the sink 10b, the washing water and the sterilizing washing water are appropriately used as described above, and the used electrolytically generated water is led out from the drain port provided at the bottom of the sink 10b to the drain groove 10c through the drain mechanism 20. Then, it is drained to a predetermined external location through the drain pipe 10d. In this case, the electrolytically generated alkaline water is alkaline and has no corrosive action on the metal, and since it does not contain residual chlorine, there is no volatilization of chlorine gas. There is no problem with the use of water.
  In contrast, electrolytically generated acidic water has a high acidity and has a corrosive effect on metals, and has a problem of corrosion, and contains a large amount of residual chlorine. Is volatilized. There are problems of corrosion and bad odor caused by chlorine gas. In order to cope with this, in the drainage mechanism 20, the trap 20c is provided with a neutralization function for neutralizing the electrolytically generated acidic water. That is, the neutralizing agent NA is accommodated in the bottom of the reservoir 21 that constitutes the trap 20c.
  For this reason, according to the drainage mechanism 20, the electrolytically generated acidic water used in the sink 10b is introduced into the trap 20c through the first drain pipe 20a from the drain outlet at the bottom of the sink 10b, and the trap 20c is stored. It passes through the layer of the neutralizing agent NA accommodated in the part 21 and is led out to the second drain pipe 20b connected to the trap 20c. During this time, the electrolytically generated acidic water once stays in the reservoir 21 of the trap 20c and sufficiently comes into contact with the neutralizing agent NA accommodated in the reservoir 21. For this reason, the electrolytically generated acidic water is sufficiently neutralized in the trap 20c and drained through the second drain pipe 20b.
  As described above, the drainage mechanism 20 effectively uses the trap 20c of the discharge mechanism 20, and the trap 20c has a function of neutralizing used electrolytically generated acidic water. For this reason, the drainage mechanism 20 has both a neutralization function and a trap function, and according to the drainage mechanism 20, there is a problem that occurs in the conventional neutralization device due to the absence of the trap 20 c, Of course, the generation of odors and chlorine gas is suppressed as much as possible, and as described above, there is no problem that is caused by incorporating it into the drainage mechanism of the neutralizer constructed separately from the drainage mechanism. And it does not become a big problem in terms of cost.
  In particular, the trap 20 c constituting the drainage mechanism 20 is provided with an inlet 24 a for supplying the neutralizing agent NA to be stored in the reservoir 21 to the reservoir 21. For this reason, it is easy to supply and replenish the neutralizing agent NA to the reservoir 21 of the trap 20c. Further, the trap 20c is formed of each molded member of acid-resistant synthetic resin, and at least the reservoir forming member 21a constituting the reservoir 21 is a transparent synthetic resin molded body, so that the trap 20c itself is corroded. In addition to being advantageous, the remaining amount of the neutralizing agent NA accommodated in the reservoir 21 can be seen from the outside through the reservoir forming member 21a. The timing can be confirmed accurately.
It is a mimetic diagram showing roughly the sink and electrolyzed water generating device provided with the drainage mechanism concerning one embodiment of the present invention. It is a side view of the drainage mechanism.
