Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a novel bath water circulation purification device that allows hot water circulation in a bathtub to be used in two ways using a switching means.

[Conventional technology]

Conventional bath water circulation devices of this type generally include a circulation pump and a desired purification mechanism, and if necessary, a heating mechanism is interposed to purify the bath water or purify and heat the bath water. Its function is to keep the bath water inside the bath in a clean state at all times.

[Problem to be solved by the invention]

In the conventional example described above, there is no problem if the bathing water is ordinary hot water, but if the bathing water contains bubble bathing agents, medicinal bathing agents, or other bathing agents, the bathing agent components may enter the filtration mechanism. There is a problem in that the filter is adsorbed or rapidly grows into filter scum, causing clogging and making it impossible to obtain a smooth circulation action.

Therefore, in the conventional example, the use of bath additives is currently prohibited.

In addition, in the conventional example, when heating is performed using an electric heater, if the heater is not energized immediately in the event of a water outage, the heater will be damaged, so a high-speed operation protection mechanism is required. If the heater comes into contact with liquid due to damage or the like, there is a risk of electric shock.

This invention was made under these circumstances,
To provide a bath water circulation and purification device which enables effective circulation to enjoy a comfortable bath despite the mixing of various bath additives and is free from dangers such as electric shock.

[Means to solve the problem]

In order to achieve the above object, the present invention configures a bath water circulation purification device as follows.

In other words, the desired purification mechanism, circulation pump, and dielectric heating mechanism using microwaves are installed in the main body of the device, which has an inlet and an outlet, and are connected to each other by the desired piping to control the bath water flowing in from the inlet. In addition to purifying and heating the water so that it can be supplied from the supply line "J", 1) the piping η is provided with a bypass piping and a switching valve mechanism to avoid the purification mechanism to switch the flow path of the bath water. This bath water circulation purification device is characterized in that it is equipped with a magnetic sterilization mechanism at a desired location of the piping, and furthermore, the purification mechanism is provided with a sterilization mechanism using a filtration material. a volumetric filtration mechanism comprising one or more filtration packages filled with fine particles;
A plate-shaped 1M filtration mechanism having a desired shape with a large number of mechanical or porous filtration holes is installed in a cylindrical housing having an inlet and an outlet, and an opening lid is provided to obtain the above-mentioned I. ! ! This bath water circulation purification device is characterized in that it can be freely packaged in over-wrapping bags and can be exchanged.

[Effect]

The bath water in the bathtub is purified and circulated through an inlet and an outlet by the action of a circulation pump provided in the main body of the device. When the bath water passing through the pipes passes through a dielectric heating mechanism using microwaves, it is heated to the desired temperature and sterilized, and then heated and sterilized into the bathtub.
Sterilized and purified hot water is supplied.

The circulation action continues during the operation of the circulation pump, and the purification effect is significantly improved.

Moreover, the scum component of bath water is the body H4 that constitutes the purification mechanism.
The filtration mechanism and area filtration mechanism provide double stage treatment, which allows for almost complete removal of everything from large to minute particles.

In addition, when mixing bath additives such as bubble bath additives or medicinal baths into bath water, the switching valve mechanism can be activated to transfer them to bypass piping that does not pass through the purification mechanism, so the chemical components in the bath additives can be transferred to a bypass pipe that does not pass through the purification mechanism. Therefore, the inconvenience of clogging the purification mechanism can be avoided.

Note that the switching valve mechanism can be automatically controlled by operating it manually or in conjunction with a means for detecting the components of the bath water being distributed, so that erroneous operation can be prevented.

Since the circulating bath water passes through a magnetic sterilization mechanism, pathogens can be killed.

〔Example〕

Hereinafter, this invention will be explained in detail with reference to Examples.

For convenience of explanation, prior to describing the embodiment, the technology on which the present invention is based will be explained with reference to FIGS. 2 to 5, and then the embodiment will be explained with reference to FIG. 1. In addition, the second
The contents of Figs. 5 to 5 are disclosed in Japanese Patent Application No. 63-319609.

(Description of FIGS. 2 to 5) Hereinafter, the same reference numerals refer to the same or corresponding parts in each section. In Figs. 2 to 4, 1 indicates the supply port 2 and the supply port 3.
4 indicates a circulation pump,
An electromagnetic pump is used to ensure safety so that even if the circulation of bath water stops due to clogging or other reasons, it will not run dry and burn out due to overcurrent. 5 represents a filtering mechanism, and 6 represents a heating mechanism.

Each of the above configurations is sequentially connected to the supply port 2 through the piping 7.
The electromagnetic pump 4, the filtration mechanism 5, the heating mechanism 6, and the supply port 3 are connected to each other so that bath water can flow therethrough.

In addition, in the piping 7 between the electromagnetic pump 4 and the filtration mechanism 5,
A cylindrical sterilizing mechanism 8 that is a permanent magnet and exhibits an inward magnetic action is attached, and a temperature sensor 9 and a flow rate sensor 10 are provided at necessary locations on the piping 7.

Next, details of the filtration mechanism 5 and heating mechanism 6 will be explained.

First, the filter mechanism 5 will be explained with reference to FIG. 5.

A lid 12 that can be opened and closed is screwed into the opening of the cylindrical housing 11, and an inlet 13 provided at the top. Outlet 14 provided at the bottom
A volumetric filtration mechanism (I) and an area filtration mechanism (II) are vertically installed between the two.

The volumetric filtration mechanism (I) stacks one or more filtration bag devices 5 made by mixing one or more types of fine particles a of various filter media and packing the mixture into bags, with a mesh plate 16 interposed between them. It is designed so that it can be supported at the upper part inside the cylindrical housing 11.

Note that when clogging develops in the filter bag device 5, if zeolite is packed in bags as the fine particles a of the filter medium or Maihan stone is stored in separate packages as the fine particles a of the filter medium, It can be taken out from the cylindrical housing 11 and purified with water or the like so that it can be used repeatedly, or it can be replaced with a new one in the case of long-term use.

A surface hI filtration mechanism (II) is connected to the rear stage of this volumetric filtration mechanism (I).

By the way, in the area filtration mechanism (■), the filter element 17 has a cylindrical shape α, and a coiled slit hole 1 formed by winding a wire with a triangular cross section is formed on the outer periphery of the headed cylinder 18.
The filtration surface 20 is formed by forming holes 9, using punched metal, or by forming porous holes using sintered metal, sintered ceramics, or the like.

The area filtration mechanism (II) is provided in the lower chamber 21 of the cylindrical casing 11, and uses a drain vibe 22 connected at one end to the lower chamber 21 to filter out grime and the like accumulated in the lower chamber 21. It is now possible to eliminate dregs.

Therefore, dirt, grime, etc. in the bath water are removed in a short time through the effective filtration and circulation of the two-stage filtration mechanisms (I) and (■), and are activated by various filter media to help the body. You can get good hot bath water.

Reference numeral 23 denotes a ceramic heater of the heating mechanism 6 connected to the filtration mechanism 5 through piping 7, which has a cylindrical shape and has a heating wire disposed therein, so that a desired desired temperature can be obtained, so that it can be used for distribution. You can reheat bath water.

Next, the switching valve mechanism 24 will be explained.

This switching valve mechanism 24 incorporates one end of the bus pass piping 7a that avoids the filtration mechanism 5 as a two-way switching valve at a place where it connects to a part of the piping 7, and protrudes from the panel surface 25 of the device main body 1. The configuration allows the legitimate child 26 to be manually switched.

The other end of this bypass piping 7a is connected to the ship [1].
2, or alternatively, the heating mechanism 6
It is possible to select various positions for connecting to the piping 7 on the upstream side of the pipe. (See Figures 3 and 4) In short, a switching valve F mechanism 24 is provided in a part of the piping 7 including the electromagnetic pump 4, and the other end of the bypass piping 7a, which has one end connected to the switching valve mechanism 24, is As long as the filtration mechanism 5 can be avoided, it may be connected to any position on the downstream piping 7.

Although the case where the switching valve mechanism 24 is manual has been described above, switching control can also be performed automatically or by an alarm. in this case,
A bath agent component detection mechanism 27 may be provided in the piping 7 leading from the inlet 2 to the filtration mechanism 5, and the detection mechanism 27 may automatically control the switching valve mechanism 24 or generate an alarm. According to this automatic control, when a bath additive is mixed into bath water, the bath additive component detection mechanism 27 is activated, the switching valve mechanism 24 switches the flow path, and immediately the mixture is mixed with the bath additive through the bypass piping 7a. Since the circulation is purified, inconveniences such as clogging caused by passing through the filtration mechanism 5 can be automatically avoided, and if there is no bath salt, the switching valve mechanism 24
Since the flow path is automatically returned to the current state and the flow path can be switched to form a circulation flow path passing through the filtration mechanism 5, the inconvenience caused by a switching malfunction can be eliminated and the operation can be carried out without any trouble.

Note that an electromagnetic pump 4.
a main switch 28 with a push button structure that activates the heating mechanism 6;
There is also a selection switch 29 with a push button structure that can adjust the temperature of the heating mechanism 6, which adjusts the temperature of the bath water, up or down.

Note that the flow rate sensor lO1 provided on the desired side pair of the piping 7
By the function of the temperature sensor 9, it is possible to immediately detect a change in the flow rate due to a clogged furnace or an abnormal rise in temperature of the circulating bath water, and automatically release the main switch 28 or activate the alarm means 30 by sound or light. It is configured so that it can be done.

Reference numerals 31 and 32 indicate the supply port 2. This is a vibe for connection with the bathtub connected to the supply port 3.

In the configuration described above, if the bathing water is ordinary Sarayu,
The bath water is circulated through a normal circulation channel passing through the filtration mechanism 5 to perform a filtration action, and is also heated by the heating mechanism 6, so that the bath water in the bathtub can be constantly maintained in a clean state.

However, when foaming bath additives or other colored chemicals are added to bath water, these components are filtered and adsorbed by the filtration mechanism 5, causing rapid clogging, which degrades the filtration mechanism and at the same time prevents smooth circulation. This results in the inability to function.

Therefore, by activating the switching valve mechanism 24 to switch the flow path of the bath water to the bus path piping 7a side that does not pass through the filtration mechanism 5, it is possible to maintain the circulating water state without any trouble.

Due to this circulating water action, the foaming bath additive can significantly improve its foaming effect and can also be used with other medicated bath additives without any problems.

(Explanation of FIG. 1) FIG. 1 is a perspective view of a "bath water circulation purification device" which is an embodiment of the present invention. Since the configuration other than the heating mechanism is the same as that of the device shown in FIG. 2, the explanation here will be omitted.

33 is a microwave generation mechanism, which is composed of a high-voltage power source and a magnetron and generates microwaves.

34 is a waveguide, 35 is a metal box, and 6a is a ceramic heating tube. The heating tube 6a has the same structure as shown in FIG.
It is connected to piping 7 and constitutes a part of the bath water circulation flow path. The waveguide 34 has one end open to the output side of the magnetron and the other end opened into the metal box 35, and supplies the microwave generated by the microwave generation mechanism 33 into the metal box 35.

Inside the metal box 35, this microwave heats the heating tube 6a.
The bath water inside is irradiated and dielectrically heated.

At that time, since the irradiation waves are in the microwave band, sterilization of the bath water is also carried out at the same time.

The heating tube 6a may be placed at any other suitable location in the bath water circulation channel, in addition to the 6 portions shown in FIG.

The metal box body reflects microwaves.

It increases heating efficiency by increasing heating efficiency, equalizes heating, and eliminates problems caused by microwave leakage, but it is not essential in terms of heating and sterilizing effects, and may be omitted depending on the configuration of the device itself. You can also. Furthermore, since this heating mechanism has a sterilizing effect as described above, the sterilizing mechanism 8 can be omitted.

〔Effect of the invention〕

According to the present invention, by adding a simple switching valve mechanism to the conventional bath water circulation purification device that only uses hot water, it is possible to prevent the mixing of bath additives by manual or automatic switching action. It can be used safely and effectively regardless of the presence or absence of foaming bath additives.In particular, when foaming bath additives are mixed in, the foaming effect expands and grows to the extent that it flows out of the bathtub due to the circulation of bath water, making bathing even more comfortable. It has the effect of allowing you to have fun.

In addition, since microwave dielectric heating is used as the heating means, it has good heating efficiency, has a sterilizing effect, and there is no risk of electric shock due to contact with liquid, and there is no particular problem with short-term water outages. Heating suitable for bath water circulation purification can be performed.

In addition, as in the case of Sarayu, bath water containing bath additives can be circulated in a sanitary manner at all times using a sterilization mechanism installed in the piping.

In the case of hot water, the filtration mechanism is a combination of a volumetric filtration mechanism and an area filtration mechanism, which has the effect of making the filtration effect extremely high.
