Description

The present invention relates to a bathroom sterilization cleaning system that utilizes ozonated water.

As a specific example of a bathroom sterilization cleaning system, there is a system equipped with an ozonated water spraying device capable of spraying ozonated water into a bathroom, as described in Patent Document 1, for example.
Here, ozonated water has a bactericidal effect. Therefore, according to the above configuration, it is possible to perform sterilization treatment on various parts such as the wall surface of the bathroom by spraying ozonated water, and to suppress the growth of mold and various germs. It is also possible to remove dirt by spraying ozone water.
Patent Documents 2 and 3 describe an air conditioner that blows ozone gas into a bathroom, but when compared with this, the configuration described in Patent Document 1, that is, the configuration that sprays liquid ozonated water, is compared. According to this method, not only can the cleaning effect of washing away dirt in the bathroom with ozonated water be obtained, but also the ozone in the ozonated water can be brought into more effective contact with each part of the bathroom, and an excellent sterilizing effect can be obtained.
Ozone water is obtained by dissolving ozone gas in water, but OH radicals, which are stronger oxidizing agents than ozone, are generated in water. Therefore, when ozone water is sprayed, it is possible to obtain a stronger sterilizing effect than when ozone gas is sprayed.

However, in the prior art, there is still room for improvement as described below.

That is, when ozonated water is sprayed into a bathroom, ozone gas is liberated from the ozonated water, so the ozone gas concentration in the bathroom increases. As this concentration increases, the ozone-specific odor becomes stronger. On the other hand, in order to thoroughly and appropriately disinfect and clean the bathroom, it is necessary to ensure that the amount of ozonated water sprayed into the bathroom is not insufficient. There must be. However, if the ozone water spraying time is increased in this manner, the ozone gas concentration in the bathroom becomes considerably high. As a result, in a situation where the ozone gas concentration is high, for example, when a person inadvertently enters a bathroom, there is a possibility that the person may feel uncomfortable. Furthermore, if highly concentrated ozone gas leaks outside the bathroom from a gap in the bathroom door, the odor may make people feel uncomfortable. It is desirable that such problems be resolved appropriately.

JP2020-48858A Patent No. 3992942 Japanese Patent Application Publication No. 11-14116

The present invention was devised under the above-mentioned circumstances, and aims to prevent the ozone gas concentration in the bathroom from becoming excessively high while efficiently and appropriately sterilizing and cleaning the bathroom using ozonated water. The objective is to provide a bathroom sterilization and cleaning system that can perform the following tasks.

In order to solve the above problems, the present invention takes the following technical measures.

The bathroom sterilization and cleaning system provided by the present invention includes a blower that can blow air into the bathroom, a ventilation device that can ventilate the bathroom by exhausting air from the bathroom to the outside, and a sterilization and cleaning process for the bathroom. and an ozone water spraying device capable of spraying ozone water into the bathroom in order to perform the sterilization and cleaning process. The ozonated water spraying operation is performed in a plurality of times with an interval period in between, and during each period of the plurality of ozonated water spraying operations, the air blowing and the ventilation are stopped, while the During the period, the air blowing and the ventilation are performed.

According to such a configuration, the following effects can be obtained.
That is, since the ozonated water spraying operation to the bathroom is executed in multiple steps with an interval period in between, the total amount of ozonated water sprayed from these multiple ozonated water spraying operations is ensured to be a sufficient amount. It is possible to appropriately perform sterilization and cleaning treatment in the bathroom. On the other hand, it is possible to reduce the amount of ozonated water sprayed by each ozonated water spraying operation. Therefore, it is possible to appropriately prevent the ozone gas concentration in the bathroom from becoming excessively high due to the release of ozone gas from the ozonated water when each ozonated water spraying operation is performed. As a result, it is possible to eliminate or reduce the possibility that a person will feel uncomfortable due to the ozone-specific odor, for example, when a person accidentally enters a bathroom.
Also, as an important effect, according to the present invention, air blowing and ventilation are performed during the interval period, so it is possible to actively reduce the ozone gas concentration in the bathroom during the interval period. Therefore, when the ozone water spraying operation is restarted after the interval period ends, the ozone gas concentration in the bathroom is more thoroughly prevented from increasing.
Ozone gas has a higher specific gravity than air and tends to accumulate at the bottom of the bathroom, but during the interval period, air is blown and ventilated to the bathroom at the same time, so ozone gas remains at the bottom of the bathroom. will be resolved appropriately. Therefore, during the interval period, it is possible to efficiently and quickly reduce the ozone gas concentration in the bathroom.
During ozone water spraying operation, air blowing and ventilation to the bathroom are stopped, so this air blowing and ventilation can be prevented from having a negative effect on ozonated water spraying operation, and the electrical energy required for air blowing and ventilation is wasted. It can be eliminated.

The present invention preferably includes a bathroom drying device capable of a bathroom drying operation for drying the bathroom, and the bathroom drying device includes the blower device, the ventilation device, and the ozone water spray device. has been done.

According to such a configuration, the following effects can be obtained.
That is, a bathroom drying device is generally equipped with an air blower or a ventilation device. If such a bathroom drying device is used as a component of the bathroom sterilization and cleaning system of the present invention, the overall configuration will be rational and preferred for cost reduction.

In the present invention, preferably, the bathroom drying operation is a state in which hot air is blown into the bathroom from the blower, and the ventilation is performed in parallel with the hot air blowing, and the ozonated water is The bathroom drying operation is configured to be executed after the final ozone water spraying operation among the spraying operations is completed.

According to this configuration, after the final ozonated water spraying operation is completed, a bathroom drying operation in which warm air blowing and ventilation are performed in parallel is executed, so ozonated water and ozone gas can be quickly removed from the bathroom. can be excluded.

In the present invention, preferably, the ozonated water spraying device includes a first nozzle for spraying ozonated water toward a side wall surface of the bathroom, and a first nozzle for spraying ozonated water toward a floor surface of the bathroom. a second nozzle, and when the ozonated water spraying operation is performed multiple times, after the ozonated water spraying operation on the side wall surface using the first nozzle is performed first; The ozone water spraying operation on the floor surface using the second nozzle is performed with the interval period in between.

According to such a configuration, the side wall surface of the bathroom is sterilized and cleaned by the ozonated water spraying operation using the first nozzle, and then, after an interval period, the ozonated water is sprayed using the second nozzle. The spraying action sterilizes and cleans the bathroom floor. Because the side walls and floors of the bathroom are separated and sterilized and cleaned separately, ozonated water is sprayed at high density on each side wall and floor to improve the sterilization and cleaning efficiency of those areas. You can also. Furthermore, since the floor surface is sterilized and cleaned after the side walls of the bathroom, the sterilization and cleaning proceeds from the upper side of the bathroom to the lower side, which also results in good sterilization and cleaning efficiency.

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

The bathroom sterilization and cleaning system SY shown in FIGS. 1 and 2 includes a bathroom drying device A. The bathroom drying device A has a configuration in which a main body part A0 installed above the bathtub 11 in the ceiling part 10 of the bathroom 1 is combined with a remote control 2 which is separate from the main body part A0. An ozone water spray device 4 is incorporated.
The bathroom drying device A is provided to receive hot water supply from the hot water supply device 8. The hot water supply device 8 is capable of supplying hot water to the bathtub 11 via a piping section 80, and has a general hot water supply function to the kitchen, etc., and is equipped with a bathroom remote control 81A and a kitchen remote control 81B.

The main body A0 of the bathroom drying device A includes a blower fan 30 (also referred to as a circulation fan), a heat exchanger 31 for air heating, a ventilation fan 32, a mist jet nozzle 33, an ozone water spray device 4, and a control section. 5. It is equipped with a casing 34 that covers the entirety of these parts.
The blower fan 30 and the ventilation fan 32 correspond to specific examples of the blower and ventilation device in the present invention, respectively.

The ventilation fan 30 is capable of sucking in air from an air intake port 35a provided on the lower surface of the housing 34 and blowing air into the bathroom 1 through a louver 36 provided at an air outlet. The heat exchanger 31 is for heating the air sucked into the blower fan 30 from the air suction port 35a, and the heat exchanger 31 receives heated hot water from the water heater 8 as a medium for this heating. It is said that it can be supplied. When the hot water supply device 8 supplies heated hot water to the heat exchanger 31 when the ventilation fan 30 is driven, the air sucked in from the air suction port 35a is heated, and warm air is sent from the louver 36 to the bathroom 1. Air is blown. During the bathroom drying operation of the bathroom drying device A, the hot air blowing described above and ventilation by the ventilation fan 32 are performed in parallel.
When the supply of heated hot water to the heat exchanger 31 is stopped, non-warm air (non-heated air) is blown from the louver 36 to the bathroom 1.

The direction of the louver 36 can be changed by a motor (not shown), and the angle at which air is blown into the bathroom 1 can be changed as appropriate.
In addition, during the interval period Pb during the sterilization cleaning process of the bathroom 1, which will be described later, as shown in FIG. ing. Preferably, the air blowing direction is such that the deflection angle with respect to the vertical line VL is in the range of 30 to 60 degrees (the range is α1 to α2 in FIG. 3, α1=30°, α2=60°).
In addition, in FIG. 3, the code|symbol 18 shows the entrance and exit of the bathroom 1, and can be opened and closed by the door 17.

The ventilation fan 32 is a fan for exhausting the air in the bathroom 1 to the outdoors. When the ventilation fan 32 is operated, air in the bathroom 1 is sucked into the casing 34 through the air suction port 35a, enters the installation area of the ventilation fan 32, and is exhausted outdoors through the exhaust port 37.
Preferably, the rotation speed of the ventilation fan 32 is variable, and when normal bathroom ventilation is performed, the rotation speed is relatively low so as to reduce the driving noise of the ventilation fan 32, whereas in the bathroom 1, which will be described later, the rotation speed is relatively low. During the interval period Pb during the sterilization cleaning process, the ventilation speed is set higher than during normal bathroom ventilation so that the ventilation capacity is increased.

The mist ejection nozzle 33 is a nozzle for ejecting a mist of hot water into the bathroom 1 when a bather wants to take a mist shower. The water supply piping section 60 for supplying hot water to the mist jetting nozzle 33 is provided with an on-off valve Va such as a solenoid valve, and a heat exchanger 61. A mist of hot water is ejected from the mist ejection nozzle 33. Heated hot water is supplied from the water heater 8 to the heat exchanger 61, and it is possible to heat the hot water supplied to the mist jetting nozzle 33. Like the louver 36, the mist jetting nozzle 33 can change its direction by a motor (not shown).

The ozone water spraying device 4 includes a piping section 40 branch-connected to a water supply piping section 60, an on-off valve Vb such as a solenoid valve provided in the piping section 40, an ozone water generator 42, and a nozzle for spraying ozone water. It is equipped with 43. As the ozone water generator 42, it is possible to use one with a conventionally known configuration, such as one that generates ozone gas by electrolysis of water using electrodes, or one that generates ozone gas from air and converts it into water. There are some methods that involve dissolving, but any method may be used. When the on-off valve Vb is set to the open state, ozonated water generated by passing through the ozonated water generator 42 is sprayed toward the bathroom 1 from the nozzle 43. For example, as shown in FIG. 4, the ozone water is sprayed from the nozzle 43 toward substantially the entire area of each side wall surface 12 of the bathroom 1 other than the upper portion, and substantially the entire floor surface 13.

The control unit 5 is configured using a microcomputer, etc., and controls the operation of each part of the bathroom drying device A, and performs drying operation of the bathroom 1, etc., as well as sterilizing and cleaning the bathroom 1, as will be described later. Execute the process. The control unit 5 is capable of wireless data communication with the remote control 2 via the communication unit 50.
The remote control 2 is, for example, portable and includes a communication circuit (not shown) for wirelessly communicating with the control unit 5 via a communication unit 50, a plurality of operation switches 20 for issuing various operation commands, a display unit 21, It is equipped with a speaker 22 that can output sounds such as voice messages.

Next, an example of the operational procedure executed in the bathroom sterilization and cleaning system SY will be described with reference to the flowchart shown in FIG. At the same time, its effect will also be explained.

The bathroom sterilization cleaning system SY of this embodiment is configured to carry out the sterilization cleaning process of the bathroom 1 in multiple times with an interval period Pb in between. Specifically, the following operations are performed. Processing is done.
That is, when the remote control 2 is used to perform an operation to start the sterilization cleaning process of the bathroom 1, the control unit 5 starts the first ozonated water spraying operation (S1: YES, S2). The spraying operation is performed in the manner described with reference to FIG. 4, and at that time, the blowing fan 30 and the ventilation fan 32 are stopped. Therefore, the ozone water spraying operation can be prevented from being adversely affected by the driving of the ventilation fan 30 and the ventilation fan 32.

The first ozone water spraying operation described above is executed for a predetermined time, for example, and when this ozone water spraying operation period Pa elapses, an interval period Pb is set thereafter, and the ozone water spraying operation ends (S3). Further, at that point, the blowing fan 30 and the ventilation fan 32 start to be driven, and blowing of air to the bathroom 1 (blowing of unheated air) and ventilation of the bathroom 1 are started. At the time when the first ozone water spraying operation is completed, a lot of ozone gas released from the ozonated water accumulates in the bathroom 1, and the ozone gas concentration is high, but during this interval period Pb, this ozone gas concentration is rapidly reduced. Is possible.

Since ozone gas has a higher specific gravity than air, it is originally difficult to smoothly exhaust it to the outside from the ventilation fan 32 installed on the ceiling 10 of the bathroom 1. On the other hand, if air is blown by the air blowing fan 30 as shown in FIG. It is possible to guide the air to the opening 35a and use the ventilation fan 32 to smoothly exhaust the air outdoors. When a person opens the door 17 and air is blown out from the louver 36 toward the washing area 1a, ozone gas is discharged from the doorway 18 and the ozone gas concentration can be reduced.

When the set time of the above-mentioned interval period Pb reaches a predetermined time and this interval period Pb ends, the second ozone water spraying operation is started (S4). In this case, the driving of the ventilation fan 30 and the ventilation fan 32 is stopped. Next, this second ozone water spraying operation is performed for a predetermined period of time, and when this ozone water spraying operation period Pc ends, the bathroom drying device A performs a bathroom drying operation (S5). In this bathroom drying operation, as described above, hot air blowing to the bathroom 1 and ventilation of the bathroom 1 by the ventilation fan 32 are performed in parallel. The bathroom drying period Pd starts when, for example, the humidity in the bathroom 1, which is detected using a humidity sensor (not shown) attached to the bathroom drying device A, drops to a predetermined value or less, or when a timer is set in advance. The process ends when the specified time elapses. By carrying out the bathroom drying operation described above, it is possible to quickly set the bathroom 1 to an atmosphere free of ozone water or ozone gas.

In the series of operating procedures described above, on/off switching control of each part as shown in the time chart of FIG. 6 is executed. The specific lengths of the first and second ozone water spraying periods Pa and Pc, the interval period Pb, and the bathroom drying period Pd in the figure are determined in advance by the manufacturer of the bathroom sterilization cleaning system SY, for example. What is necessary is to find a value (time) that is considered to be optimal or close to optimal, and then apply this value. However, considering the size of the bathroom 1 and various other conditions, the length of each of the periods Pa to Pd may be changed as appropriate by the user operating the remote control 2. .

According to the bathroom sterilization and cleaning system SY of the present embodiment, when performing sterilization and cleaning of the bathroom 1, the ozone water spraying operation is performed twice with an interval period Pb in between. Moreover, during the interval period Pb, the ozone gas generated in the bathroom 1 due to the first ozone water spraying operation is discharged outdoors. Therefore, it is possible to appropriately prevent the ozone gas concentration in the bathroom 1 from becoming higher than a predetermined level during each ozone water spraying operation. As a result, for example, when a person accidentally enters the bathroom 1, it is possible to eliminate or reduce the possibility that the person will feel uncomfortable due to the ozone-specific odor.
On the other hand, since the total amount of ozone water sprayed into the bathroom 1 by the two ozone water spraying operations can be made into a sufficient amount, the bathroom 1 can be appropriately sterilized and cleaned.

7-10 illustrate other embodiments of the invention. In these figures, elements that are the same as or similar to those of the embodiment described above are given the same reference numerals as those of the embodiment described above, and redundant explanation will be omitted.

The ozone water spray device 4a included in the bathroom drying device Aa of the bathroom sterilization and cleaning system SY' shown in FIG. The ozonated water generated by the ozonated water generator 42 can be selectively supplied to either one of the first and second nozzles 43A and 43B. As shown in FIG. 8(a), the first nozzle 43A sprays ozonated water toward the side wall surface 12 of the bathroom 1, and hardly sprays it toward the floor surface 13. On the other hand, the second nozzle 43B sprays ozone water toward the floor surface 13 of the bathroom 1, and hardly sprays it toward the side wall surface 12, as shown in FIG. 8(b).

In the bathroom sterilization and cleaning system SY' of this embodiment, when the bathroom 1 is to be sterilized and cleaned, the operation process shown in the flowchart of FIG. 9, for example, is executed.

Specifically, in step S2', the first ozone water spraying operation is performed, and this operation is performed in the manner shown in FIG. 8(a). That is, ozonated water is sprayed toward the side wall surface 12 of the bathroom 1 using the first nozzle 43A. Next, in step S4', a second ozone water spraying operation is performed, and this operation is performed in the manner shown in FIG. 8(b). That is, ozonated water is sprayed toward the floor 13 of the bathroom 1 using the second nozzle 43B.

According to such an operation procedure, the side wall surface 12 of the bathroom 1 is intensively sterilized and cleaned by the first ozonated water spraying operation, and the floor surface 13 of the bathroom 1 is intensively cleaned by the second ozonated water spraying operation. Sterilized and cleaned. Therefore, it is possible to make the sterilization and cleaning efficiency for each of the side wall surface 12 and floor surface 13 of the bathroom 1 better than that of the embodiment described above.

In the ozonated water spraying device 4b shown in FIG. 10(a), the second nozzle 43B is supplied with ozonated water generated by the ozonated water generator 42, whereas the first nozzle 43A is supplied with the ozonated water generated by the ozonated water generator 42. It is configured to provide normal water supply (in FIGS. 10(a) and 10(b), symbols Vc to Ve indicate on-off valves similar to on-off valves Va and Vb).
According to such a configuration, after the side wall surface 12 of the bathroom 1 is sprayed with normal water from the first nozzle 43A to a so-called washing state, ozonated water is sprayed from the second nozzle 43B into the bathroom 1. The floor surface 13 will be sprayed and sterilized and cleaned.
Note that the ozone water spraying operation in the present invention is performed in multiple steps with an interval period in between. Therefore, the ozone water spraying operation from the second nozzle 43B is repeatedly performed in multiple steps with an interval period in between.

In the ozonated water spraying device 4c shown in FIG. 10(b), as in FIG. 10(a), the ozonated water generated by the ozonated water generator 42 is supplied to the second nozzle 43B; The configuration is such that it is not supplied to the first nozzle 43A. However, hot water that has passed through the heat exchanger 61 and is heated can be supplied to the first nozzle 43A.
According to such a configuration, when hot water is sprayed from the first nozzle 43A onto the side wall surface 12 of the bathroom 1, the hot water can be turned into hot water, compared to the case of FIG. 10(a). , it is possible to improve the cleaning ability for the side wall surface 12.

The present invention is not limited to the content of the embodiments described above. The specific configuration of each part of the bathroom sterilization and cleaning system according to the present invention can be modified in various ways within the intended scope of the present invention.
