[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for switching and releasing cluster ions and negative ions, and in particular, an ion emission apparatus for a bathroom that discharges these ions to a bathroom, a bath with the same, and a bathroom that controls the method for releasing these ions. The present invention relates to an ion emission control method.
[0002]
[Prior art]
In recent years, there have been devices that give people a refreshing feeling close to a forest bath by releasing negative ions into the atmosphere. However, negative ions have little effect on positive removal of bacteria floating in the air. On the other hand, there are devices with functions to disinfect air, deodorize, and suppress mold by releasing a large amount of cluster ions consisting of approximately the same number of positive ions and negative ions into the air ( Patent Document 1).
[0003]
H as a positive ion⁺(H₂O)_n, O as negative ions₂ ^-(H₂O)_mOccurs most stably. These positive ions and negative ions alone have no particular sterilization effect against airborne bacteria in the air, but when they occur at the same time, hydrogen peroxide H, which is an active species, is generated by a chemical reaction.₂O₂Alternatively, hydroxyl radicals (.OH) are generated. This H₂O₂Or (.OH) shows extremely strong activity, and it is said that floating bacteria can be removed by sending them into the air.
[0004]
The toilet / integrated shower toilet has a function to release cluster ions, a function to release negative ions, and a function to detect the presence or absence of a person. When a person is not in the toilet, the cluster ion is released to sterilize and deodorize the toilet. There is a type in which mold is suppressed, a person is detected by a seating sensor or the like, and when there is a person, negative ions are emitted to obtain a refreshing effect (see Non-Patent Document 2).

[Problems to be solved by the invention]
Even in the bathroom, it is desirable to suppress mold, disinfect and deodorize, and when entering the bathroom, if there is a refreshing feeling like a forest bath, users will be pleased. However, the bathroom is larger than the toilet, so once the interior of the bathroom is filled with cluster ions, it takes a long time to fill the bathroom with negative ions even after switching to the release of negative ions. Cost. Therefore, even when switching from the release of cluster ions to the release of negative ions when it is detected that a person has entered the bathroom, a refreshing feeling like a forest bath cannot be immediately given to a person who has entered the bathroom.
[0007]
In addition, the family often bathes for a short time, so if you start releasing the cluster ions immediately after the first person comes out, the next time the second person comes in, the bathroom is cluster ions. It will be satisfied. Thus, in the bathroom, simply detecting the presence or absence of a person and switching the emission of cluster ions and the emission of negative ions based on this detection cannot provide an appropriate air environment.
[0008]
The present invention has been made paying attention to such problems, and appropriately controls the release time of cluster ions and negative ions to form an air environment in the bathroom that matches the presence or absence of an actual person. It is an object of the present invention to provide a bathroom ion release apparatus and a bathroom ion release control method that can be used.

[0024]
Next, the operation of the invention described in each of the above items will be described.
The ion release device for bathroom includes a cluster ion release means (11) for generating and releasing cluster ions, a negative ion release means (12) for generating and releasing negative ions, and a release timing of the cluster ions and negative ions. And a release timing control means (13) for controlling. The release timing control means (13) controls the release time of the negative ions and the release time of the cluster ions according to the operation status of the bath tub in conjunction with the control device for the bath tub.
[0025]
For example, it is assumed that a person enters the bathroom when the bath is boiling. It can be predicted that people will continue to enter the bath while the bath is warming. When the warming operation is turned off, it is assumed that a person does not enter the bathroom for bathing thereafter. When taking a shower, it can be determined that a person is in the bathroom. By monitoring the water level of the bathtub, it can be determined that a person has entered the bathtub or has left the bathtub. In this way, it is possible to assume the behavior of people entering and exiting the bathroom through the operation status of the bath, so by switching the cluster ions and negative ions based on the operation status of the bath and controlling the release timing, An air environment suitable for people coming and going can be created in the bathroom.
[0026]
More specifically, the release of negative ions starts when the automatic operation of the bath is turned on or when the memorial operation is turned on. It takes several tens of minutes from the start of the water pouring operation or the chasing operation to the bathtub until the hot water pouring or chasing is completed and a person can take a bath. Therefore, by starting the release of negative ions from when the automatic operation of the bath pot is turned on or when the memorial operation is turned on, when the person takes a bath, the bathroom is filled with negative ions. be able to.
[0027]
Release of negative ions starts from a point in time after a predetermined time has elapsed from the time when the bath pouring operation or the memorial operation is completed and the person is expected to be able to bathe. For example, the release of negative ions is started when the water level at the time of automatic pouring rises to a certain level below the water level at the time of completion of pouring. In addition, when a bath boiling completion time is reserved, the release of negative ions is started from a time that is a predetermined time after that time. How long before the start of the release of negative ions may be set as appropriate, for example, based on the size of the bathroom, the capacity of the bathtub, the memorial ability, and the like. The negative ions can be released from the point in time after the pouring completion time etc. for the time necessary to fill the bathroom with the negative ions, and unnecessary discharge is prevented, contributing to energy saving.
[0028]
Release of negative ions may be started when the temperature of the bath water rises to a water temperature that is a predetermined temperature lower than the set temperature of the bath. Since it takes several minutes to raise the temperature from a temperature somewhat lower than the set temperature to the set temperature, the bathroom can be filled with negative ions during this time. This prevents unnecessary release of negative ions. How many times lower than the set temperature should be set as appropriate to start the release of negative ions, so that when the set temperature is reached, the bathroom is filled with negative ions. It may be determined based on the ability of dredging.
[0029]
When the operation to keep the bath water at the set temperature is completed, it is assumed that the person will not enter the bathroom after the heat insulation operation is completed. Can be switched at an appropriate timing for the release of.
[0030]
When it detects that a person is in the bathroom, it stops the release of negative ions or switches to the release with a breeze. The release of negative ions is accompanied by ventilation. When this wind hits a naked body, it may cause discomfort. The bathroom is already filled with negative ions. Therefore, after detecting the person entering the room, it is possible to give a more refreshing feeling by stopping the release of negative ions or switching to a breeze. For example, a person entering a room may be detected by providing an infrared human sensor or a door switch on a bathroom door.
[0031]
It may be determined that the person has entered the bathtub based on the rise in the water level in the bathtub, and when the person is bathing, the release of negative ions may be stopped or switched to the release with a light breeze. By monitoring the rise in the water level in the bathtub, it can be detected that a person has entered the bathtub. Therefore, when it is detected by a rise in water level that a person is actually in the bathroom, the release of negative ions is stopped or switched to a breeze. Thereby, it is prevented that the wind at the time of negative ion emission hits a human body directly and gives unpleasant feeling.
[0032]
When it is detected that a person has left the bathroom, the release of negative ions is resumed or the air volume is restored. Thereby, it becomes possible to give a refreshing feeling due to negative ions to the next person. The fact that a person has left the bathroom is detected by, for example, an infrared human sensor or a door switch.
[0033]
Furthermore, it may be determined that a person has left the bathtub based on a drop in the water level in the bathtub, and when a predetermined time has elapsed since the person left the bathtub, the release of negative ions may be resumed or the air volume may be restored. . By waiting for the passage of a predetermined time after the person leaves, it is possible to prevent the negative ions from being released while the person is in the washing area after leaving the bathtub and the wind hitting the body.
[0034]
Furthermore, it may be determined whether or not a person is in the bathroom based on the state of the hot water, and while the person is in the bathroom, the release of negative ions may be stopped or switched to the release with a light breeze. It is assumed that there are people in the washing area during the hot spring. Since the wind is more worrisome at the washing place than when it is in the bathtub, it is effective to stop the release of negative ions during tapping.
[0035]
Release of cluster ions starts when this state continues for a predetermined time after the water level in the bathtub falls below the circulation port (6). It can be detected that the bathtub has been unplugged when the water level in the bathtub is equal to or lower than the circulation port (6), and thereafter it can be assumed that a person does not enter the bathroom for bathing. In addition, waiting for the elapse of a predetermined time may occur when the water in the bathtub is low, because the water level may temporarily fall below the circulation port (6) due to people entering or leaving the bathtub. This is to avoid the problem.
[0036]
When the operation state in which the bath water is kept at the set temperature is finished, the release of cluster ions may be started. While the bath water is warming, it is expected that the next person will still enter the bathroom, but when the warming mode ends, it is assumed that the person will not bathe afterwards, so the switch to cluster ion release As appropriate. When the operation state to keep warm is finished, when the automatic operation is turned off, when a specified time such as 4 hours has elapsed from the start of the automatic operation, when the timer automatically turns off the operation, the person manually operates There are times when is turned off. Note that the cluster ions may be released after a predetermined time has elapsed after completion of the heat retention operation state. This is due to the fact that a person taking a bath may intentionally release the heat-retention operation in consideration of energy saving or the like just before leaving the bath.
[0037]
By the way, there are a lot of negative ions and a lot of positive ions around waterfalls and fountains. In waterfalls and fountains, ions are not generated by electrical means, so the same number of negative ions and positive ions should be generated, but in reality there are considerably more negative ions. This is because small water droplets that are negatively charged due to the Raynard effect float and diffuse around, releasing electrons to the surroundings (observation platform, bench, etc.), but the water droplets that are positively charged are large and difficult to float, making it foggy. For example, it falls to a waterhole. As a result, it is considered that there is a difference in the number of negative ions and positive ions. In other words, it is thought that there are more positive ions in the smoke immediately below the waterfall and the fountain, and this is presumed to be the cause of the presence of many negative ions at the observation deck around the waterfall and the benches around the fountain.
[0038]
If you take a shower vigorously, the same number of negative ions and positive ions are generated by the Reynard effect. There are also products on sale (shower heads that generate negative ions). However, since the increase in positive ions has been measured rapidly after the shower, small water droplets that are negatively charged due to the Raynard effect collide with the wall surface before floating and diffusing and releasing electrons to the surroundings. It is presumed that the water droplets, which have lost their charge and are positively charged, become mist and drift in the bathroom. In other words, the bathroom is in the same state as fog or clouds filled with moist steam (steam), and the steam is filled with positive ions, just in the smoke just below the waterfall or fountain. It is presumed that it is in the same state.
[0039]
Even if cluster ions are released in a bathroom filled with mom and steam (water vapor), the number of negative ions in the cluster ions is reduced by the steam and the balance of the same number of negative and positive ions required for sterilization is lost. . Therefore, it is possible to obtain a higher effect by discharging the cluster ions after discharging the hot / cold smoke outside the bathroom by ventilation before releasing the cluster ions. If a predetermined amount of negative ions is emitted before the cluster ions are released, the positive ions remaining in the bathroom (since ventilation only dilutes the positive ions) can be neutralized, and a higher effect can be obtained.
[0040]
When starting the release of cluster ions, the bath room temperature apparatus is activated. As described above, water droplets are easily positively charged and cause the balance of positive ions and negative ions to be lost. Therefore, by quickly forming a state without water droplets, the sterilization effect and mold suppression effect by cluster ions are more effective. Effectively demonstrated.
[0041]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a configuration of a bathroom ion release device 10 and a bath tub 50 according to an embodiment of the present invention. The bathroom ion emitter 10 is installed in the bathroom. The bathroom ion emitter 10 generates cluster ions composed of approximately the same number of positive ions and negative ions, and releases them into the air with a fan, and generates negative ions into the air with a fan. It has a negative ion release means 12 and a release timing control means 13 for controlling the release timing of cluster ions and negative ions.
[0042]
An apparatus for generating ions, for example, generates positive ions and negative ions simultaneously on the outside of a glass tube as a dielectric by applying an alternating voltage of about 1.75 Kv between a high-voltage electrode and a ground electrode. At this time, the concentration of positive ions and negative ions is about 20,000 / CC, and the ozone concentration is 0.01 PPM or less. The release timing control means 13 includes a CPU (Central Processing Unit), a ROM (Read Only Memory) for storing programs and various fixed data, and data temporarily required for executing the programs. A RAM (Random Access Memory) for storage is configured as a main part.
[0043]
The discharge timing control means 13 has a function of receiving various data indicating the operation status of the bath 50 through a connection wiring from a bath control device 51, which will be described later, and controlling the release timing of cluster ions and negative ions based on this data. .
[0044]
The bath pot 50 includes a bath pot control device 51 that controls and controls the entire operation of the bath pot, a remote controller 60 that accepts setting operations from the user and displays operation status, a burner, a heat exchanger, and bath water. It is comprised from the hot water bath part 70 provided with the circulation pump etc. The bath pot 50 has a function of heating the water supply and pouring the water into the bathtub 5 and a function of tracking the bathtub water in the bathtub 5. When the automatic operation is turned on, the hot water is filled up to the set water level, and then the heat retaining operation is performed to keep the bath water at the set temperature until a certain time (four hours in this case) elapses.
[0045]
The heat receiving pipe passing through the heat exchanger of the hot water bath part 70 is connected to the circulation port 6 of the bathtub 5 by a water pipe. The water pipe includes a bath return pipe 52 that returns the bathtub water in the bathtub 5 to the hot water bath pot section 70, and a bath outlet pipe 53 that feeds the bath water heated in the hot water bath pot section 70 into the bathtub 5. During the memorial operation, water is fed by a circulation pump inserted in the middle of the bath return pipe 52, and the bath water is sent from the bathtub 5 to the bath return pipe 52, the heat receiving pipe of the heat exchanger of the hot water bath portion 70, It circulates to return to the bathtub 5 through the bath outlet pipe 53. During the pouring operation, the water supplied from the water supply pipe is heated through the heat receiving pipe of the heat exchanger, and this is sent to the bathtub 5 from the circulation port 6 through the bath outlet pipe 53. During the warming operation, the circulation pump is sometimes operated to check the temperature of the bath water, and if necessary, the memory operation is performed.
[0046]
The hot water bath portion 70 includes a water level sensor 71 and a temperature sensor 72. The water level sensor 71 detects the water level in the bathtub 5. The temperature sensor 72 detects the water temperature of the bathtub water circulating through the bath return pipe 52 and the like.
[0047]
The remote controller 60 includes an operation switch 61, a display unit 62, and a timer unit 63. The remote controller 60 includes a main switch for switching on / off of the appliance, an automatic operation switch, a temperature setting switch for setting the temperature of the hot water and the temperature of the bath, a switch for reserving the automatic boiling time of the bath, and the like. The display unit 62 is composed of a liquid crystal display and has a function of displaying the operation status of the appliance, the set temperature, and the like. The timer unit 63 is used to time the elapsed time in order to automatically turn off the driving 4 hours after the automatic driving is turned on.
[0048]
Next, the operation will be described.
FIG. 2 shows the flow of the cooperative operation between the bathroom ion release device 10 and the bath pot 50. In the bathtub 50, when the user's operation or reservation time arrives and automatic operation starts, a timer for limiting the duration of this automatic operation is turned on (step S101), and automatic pouring starts (step S101). S102). When the pouring operation is slightly completed (here, about 5 minutes before) (step S103; Y), a signal indicating that is sent from the bath pot control device 51 to the discharge timing control means 13 and received. The bathroom ion release device 10 starts releasing negative ions (step S104).
[0049]
Here, detection that automatic pouring is completed in a short time (in about 5 minutes) is detected by, for example, monitoring the pouring amount and comparing the current pouring amount with the pouring amount until completion of pouring in advance. To do. In addition, when the bath water is further heated to the set temperature after the pouring is completed, the negative ion release start timing may be detected in consideration of the time. In the case of memorial operation, the temperature of the bath water is monitored, and when the bath water rises to a predetermined temperature lower than the set temperature of the bath, it is time to start releasing negative ions Is determined. In addition, when the automatic operation is turned on, if the bathtub is already filled with water, it is performed with a small amount of pouring or no pouring. In this case, it is only necessary to detect the start timing of the negative ion release based on the water temperature of the bath water as in the case of the chasing operation.
[0050]
Between the start of negative ion release and the completion of the automatic pouring operation and the chasing operation, the bathroom is filled with negative ions. It should be noted that it is possible to automatically or manually switch the number of minutes before the completion of the automatic pouring and chasing operation to start the release of negative ions. For example, the discharge start timing is switched automatically or manually according to the size of the bathroom. In the case of automatic, it is good to have a learning function. That is, the time required for the bathroom to be filled with negative ions is learned, and thereafter, the release of negative ions may be started at a timing that is earlier than the scheduled completion time of the pouring operation or the like.
[0051]
After the automatic pouring operation or the like is completed, the rise in the water level in the bathtub is sensed by the output of the water level sensor 71, and based on this, the presence or absence of bathing of the person is monitored to detect that the person has bathed (step S105). Y), the release of negative ions is stopped (step S106). Instead of stopping the release, the amount of air blown when releasing negative ions may be switched to a light wind. In this way, by stopping the release of negative ions or making it a breeze, it is possible to prevent the wind for release from directly hitting the skin and causing discomfort to the person in the bathroom. Detection of a person's bathing due to a rise in the water level may be determined on the condition that the rate of increase in the water level per unit time is a certain level or more, and that the state where the water level has risen is maintained for a certain period or more.
[0052]
It should be noted that another way to detect that a person has entered the bathroom, such as using a door switch, an infrared motion sensor, or a speaker in the bathroom remote control instead of a sound collecting microphone, makes a voice in the bathroom. When detecting that the person has entered the bathroom, the release of negative ions may be stopped, or switching to a breeze may be performed. Also, it is determined whether the person is in the bathroom based on the condition of the hot water, and during the hot water or during the hot water and for a few minutes after the hot water is stopped, the release of negative ions is stopped or a slight breeze May be switched to release.
[0053]
Judgment based on the condition of the hot water may determine whether a person is in the bathroom with the currently used ability. For example, when dropping hot water into a bathtub or taking a shower, generally the capacity of No. 10 or more is often used. On the other hand, since only about 5 to 10 is used in the kitchen, for example, 10 is used as a reference value for judgment, and the discharge of negative ions is stopped for 10 minutes after stopping the hot water discharge of 10 or more, or in a breeze You may switch to discharge.
[0054]
While human bathing is not detected (step S105; N), the release of negative ions is continued.
[0055]
After detecting the person's bathing, it is monitored whether or not the person taking the bath has gone out of the bathtub 5 based on the water level drop, and when it is detected that the person has gone out of the bathtub 5 (step S107; Y), the minus is again performed. Release of ions is started or the air flow rate is returned from the slight wind to the original air flow (step S104). The start of the negative ion release and the return of the air volume may be performed after a predetermined time has elapsed from the time when it is detected that a person has left the bathtub 5. This is because there is a possibility that there is a person in the washing place for a while after leaving the bathtub 5. In addition, when another person detects that he / she has left the bathroom, such as a door switch or infrared human sensor, and detects that the person has left the bathroom, the release of negative ions can be resumed or the air volume can be reduced. It may be restored.
[0056]
Regardless of whether or not negative ions are being released or whether a slight wind is being emitted, when the specified time (4 hours in this case) has elapsed since the start of automatic operation, or when automatic operation is manually turned off (Step S108; Y or S109: Y), the release of negative ions is stopped (Step S110). As described above, after the automatic operation is stopped, that is, after the operation mode in which the bath water is kept warm is released, it is assumed that no more people enter the bathroom for bathing. Stop the release of. Note that after releasing the heat retention mode, the release of cluster ions may be started after a lapse of a predetermined time. This is because it may be assumed that a person taking a bath intentionally turns off the heat-retaining operation in consideration of energy saving or the like slightly before leaving the bath.
[0057]
In addition, for example, the water level in the bathtub is monitored, and it is determined that the bathtub 5 is unplugged based on the fact that the water level is lower than the circulation port 6. Release may be stopped. When the bath water is low, the water level may temporarily fall below the circulation port 6 due to the entry or exit of the bathtub 5 and so on, so that the water level is lower than the circulation port 6 in order not to mistake this as drainage. It may be determined that the plug has been removed and drained at a point in time when the pressure has continued for more than a certain level.
[0058]
Next, if there is a bathroom ventilation fan, it is operated for a predetermined time to perform ventilation (step S111). Positive ions are easily charged with vapor (large water droplets) floating in the bathroom, and negative ions attach to small water droplets and move a lot (small water droplets and large water droplets receive the same force from the airflow in the bathroom). But the amount of movement is different). Therefore, as time passes, it hits the wall and the charge flows to the ground. For this reason, even if the cluster ions are released in a state where the steam is filled in the bathroom, the balance between the positive ions and the negative ions is lost, and it is difficult to obtain an effect such as sterilization. Accordingly, the exhaust of the cluster ions is started after the ventilation fan is operated and the steam in the bathroom is discharged (step S112). Thereby, the effect of sterilization etc. can be ensured efficiently. In addition, if a hot air device such as a bathroom heater / dryer is installed in the bathroom, it can be operated and water droplets can be removed quickly, so that the sterilization effect and fungus control effect by the cluster ions can be exhibited more efficiently. The
[0059]
The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to this, and there may be changes and additions within the scope not departing from the gist of the present invention.
[0060]
For example, in the embodiment, the bathroom ion release device 10 and the bath tub 50 are configured as independent devices, but may be configured as a bath tub 50 incorporating the bathroom ion release device 10. Furthermore, it is good also as a structure which incorporates the bathroom ion discharge | release apparatus 10 in a bathroom heating dryer.
[0061]
Further, in the embodiment, the release of negative ions is started from a predetermined time before the scheduled completion time of the pouring operation or the scheduled completion time of the chasing operation, but when the automatic operation is turned on or the chasing operation is turned on. The release of negative ions may be started from that time. When the timer reservation is made for the completion time of the automatic bath operation, the negative ion release may be started at a time that is a predetermined time later than the reserved completion time.
[0062]
【The invention's effect】
According to the ion release device for bathroom according to the present invention and a bath tub provided with the same, and a bathroom ion release control method, the release time of negative ions and the release time of cluster ions are controlled according to the operation status of the bath tub. These ions can be switched and released at an appropriate timing in accordance with the entry / exit of the person to / from the bathroom, and an air environment suitable for the presence or absence of the person can be formed in the bathroom.
[0063]
For those that start releasing negative ions from the time when automatic operation of the bath is turned on or the time of memorial operation is turned on, the inside of the bathroom may be filled with negative ions when a person takes a bath. it can. In the case where the release of negative ions starts after a predetermined time has elapsed from the time when the bath pouring operation or memorial operation is completed and the person is scheduled to be able to take a bath, negative ions are released more than necessary. Contributes to energy saving.
[0064]
When the operation of keeping the bath water at the set temperature is completed, it is assumed that people will not enter the bathroom after the heat insulation operation is completed. Can be switched at an appropriate timing for the release of.
[0065]
When it is detected that a person is in the bathroom, the release of negative ions is stopped or switched to the release by a light wind, and it is prevented that the wind at the time of negative ion emission directly hits the human body and gives unpleasant feeling. When it is detected that a person has left the bathroom, it is recommended to restart the release of negative ions or restore the air volume. This makes it possible to give a sufficient refreshing feeling to the next bather.
[0066]
It is determined whether or not a person is in the bathroom based on the condition of the hot water, and while the person is in the bathroom, the release of negative ions is stopped or switched to the release by a light wind. When people are in the washroom, wind discomfort tends to occur. It is also assumed that people will be in the washroom during the hot spring. Therefore, it is possible to effectively prevent discomfort due to the wind by determining the presence or absence of a person based on the hot water situation.
[0067]
When it is detected that the water level of the bathtub has fallen below the circulation port and the bathtub has been unplugged, or when the operation state of keeping the bathtub water at the set temperature is completed, cluster ion release is started. Thereafter, it is assumed that a person does not take a bath, so that it is possible to switch to the emission of cluster ions at an appropriate timing.
[0068]
In the case where the bathroom ventilation fan is operated for a predetermined time before the start of the cluster ion release, the vapor that causes the ion balance to be lost before the cluster ion release is expelled, so that the sterilization effect and the like can be obtained efficiently.
[0069]
When starting the release of cluster ions, a device that operates a bath room temperature apparatus can quickly form a state without water droplets, and the sterilization effect and mold suppression effect by cluster ions are more effectively exhibited.
