Description

  The present invention relates to a mist device used for obtaining a feeling of sauna by spraying heated hot water with a mist on an indoor space such as a bathroom, and drying by blowing hot air to the indoor space of a bathroom. For the bathroom dryer with a mist function that adds the mist function of spraying the above mist to the bathroom dryer to be used, in particular, avoiding the clogging of the nozzle for spraying the mist and eliminating the clogging that has occurred It is related to technology to do.

  Conventionally, various techniques for preventing clogging of an air outlet or an injection port (hereinafter collectively referred to as “nozzle”) through which mist is sprayed have been proposed. For example, from the viewpoint that adhesion of scales and the like is triggered by repeated wetting and drying, the nozzle should be kept moist and not dried while the steam (high humidity hot air) blowing operation is stopped. In order to achieve this, a water storage tank is installed in the vicinity of the nozzle, and water supplied from the water storage tank is stored and supplied to the nozzle when operation is stopped (see, for example, Patent Document 1). Alternatively, the nozzle is made of a water-repellent resin material such as polypropylene, polyethylene or fluorine resin, coated with the same material, or metal-plated. There is also known an apparatus in which a pneumatic mechanism is operated after use to blow away residual water in a pipe from a nozzle (for example, see Patent Document 2).

Japanese Patent No. 3252484 JP 2002-13748 A

  However, in the conventional techniques as described above, it is necessary to add a special device to prevent clogging of the nozzles, which increases the cost or takes up space and contradicts the demand for compactness. Invite the situation. On top of that, when a mist device is newly installed, it is possible to install a mist device with measures to prevent nozzle clogging, but it is not possible to take measures against an already installed mist device. , It will also be uneconomical to be replaced.

  The present invention has been made in view of such circumstances, and its purpose is to prevent mist from clogging or eliminate clogging without requiring additional installation of a special device or the like. It is to provide a bathroom dryer with a device or a mist function.

  In order to achieve the above object, in the first invention relating to the mist device, the cleaning function of the nozzle is achieved by utilizing the components already provided and controlling the operation thereof. As a principle of this, the area upstream of the nozzle is closed in a closed state, the residual water remaining in the closed area is heated and expanded to increase the internal pressure, and the mist from the nozzle under the increased internal pressure. By performing a cleaning operation of discharging (mist ejection), clogging is eliminated and clogging is prevented.

That is, in the first invention, the heat of the nozzle for spraying mist, the supply passage for supplying mist water to the nozzle, and the heat medium provided in the supply passage for supplying the mist water for the heat source. A liquid / liquid heat exchanger to be heated by exchange, a water supply valve interposed in an upstream supply passage of the liquid / liquid heat exchanger, a downstream side of the liquid / liquid heat exchanger, and the nozzle A mist provided with a spray valve interposed in the upstream supply passage, and a control means for performing a mist operation by controlling the switching operation of the water supply valve and the spray valve and the heating operation control of the liquid / liquid heat exchanger. to the device to subject, and further comprising a drain passage which branches from the supply passage between said liquid-liquid heat exchanger and the spray valve, performing a cleaning operation for cleaning the nozzle to control written above means The following cleaning operation control modes are provided. Was Rukoto. That is, the cleaning operation control mode, Ri by the opening and closing switching operation of the opening and closing switching action dynamic and drain valve interposed in the drain passage of the water supply valve and spray valve, liquid-liquid heat of the upper Symbol supply passage partial and specific channel area is a portion of the drain passage to the drain valve through branch communicating to the supply passage between the sandwiching exchanger feedwater valve to spray valve, is filled with mist water to the inner portion, Sealing control for closing and closing the mist water in a state filled with mist water, and heating and operating the liquid / liquid heat exchanger in this sealed and closed state to raise the temperature of the mist water in the specific passage area and to expand the volume. The pressure increase control for increasing the internal pressure of the specific passage region to a predetermined internal pressure value and the ejection control for discharging the mist water in the specific passage region after the pressure increase control from the nozzle are sequentially executed. .

More cases of the first invention, the sealing control, the interior of the particular passage area is in a closed Shimekiri state while being filled with mist water, then the boost control, the mist water of the specific passage area As the temperature rises, the volume expands accordingly, and the internal pressure in the specific passage area increases. Then, the ejection control, or mist of water for pressure elevated high pressure state is supplied by being ejected as a mist from the nozzle, clogging eliminated peeled a water stain adhering to the nozzle or the like is achieved, The occurrence of clogging can be prevented by blowing off the scales adhering to the nozzle. Such a cleaning function is realized by using various valves and liquid / liquid heat exchangers normally provided in the mist device and controlling their operation, and special equipment for boosting is used. There is no need to add.

Further, either when Cal first invention, further comprising a drain passage which branches from the supply passage between said liquid-liquid heat exchanger and the spray valve, of the waste water passage interposed drainage valve as the closed control because it is configured to perform even together the opening and closing switching operation, even drainage in the supply passage after the last of the mist operation end has been carried out through the drain passage, by performing the opening and closing switching operation of the drain valve It becomes possible to reliably fill the mist water into the specific passage area having the drain valve as a boundary.

Further, in the first invention described above, a notification means is further provided, and the cleaning operation control mode indicates that the cleaning operation is performed prior to executing the cleaning operation and / or during the cleaning operation. It can be set as the structure further equipped with the alerting | reporting control which alert | reports that it is performing driving | running | working by the said alerting | reporting means (Claim 2 ). In this way, since the user knows that the cleaning operation is being executed automatically rather than being abnormal, a relatively high temperature mist will be ejected vigorously, It is possible to grasp and avoid exposure to the mist.

On the other hand, any one of the above mist devices is installed, and heat dissipation heat exchangers that are heated by heat dissipation from the heat medium supplied for the heat source and heat generated by the heat dissipation heat exchanger are generated. In the second invention intended for a bathroom dryer with a mist function provided with a blower to be blown into the bathroom space, as the cleaning operation control mode, when the water for mist in the specific passage area after the pressure increase is ejected from the nozzle. In addition, it is configured to perform control for forcibly operating the blower (claim 3 ). In the case of the second aspect of the invention, although a relatively high temperature mist is ejected during the cleaning operation of the installed mist device, the mist comes out of the nozzle and comes into contact with the forced air flow generated by the blower. Therefore, even if the user touches the mist after that, it is possible to lower the sensible temperature.

Furthermore, in the second invention, a drive louver that forcibly rotates the angle of the blowing direction with respect to the bathroom space by changing the rotation angle is further provided, and the cleaning operation control mode includes a specific passage area after pressure increase. When the water for mist is ejected from the nozzle, the louver can be controlled to forcibly rotate to a preset cleaning mode angle. And, as the cleaning mode angle at that time, setting the rotation angle that can forcibly change the flow of mist ejected from the nozzle toward the place where the human body in the bathroom space is predicted to be absent (Claim 4 ). By doing so, in addition to the mixing and stirring by contact with the forced air flow described above, the direction of the mist flow ejected from the nozzle is forcibly changed so that it does not contact the human body reliably. Will be done.

As described above, according to the mist device of any one of the first to second aspects, the high pressure control is performed by executing the sealing control and the pressure increasing control as the cleaning operation control mode and then performing the ejection control. Mist can be ejected from the nozzle by supplying water for mist, and the pressure at the time of ejection eliminates clogging by peeling off the water scale adhered to the nozzle, and blows off the water scale adhering to the nozzle and clogs. It is possible to reliably prevent the occurrence. And since such a cleaning function is realized by using various valves and liquid / liquid heat exchangers normally provided in mist devices and controlling their operation, special equipment for boosting Therefore, the present invention can be applied to an existing mist device having no cleaning function. As described above, it is possible to provide a mist device that can prevent or eliminate clogging of nozzles without requiring additional installation of a special device or the like.

In addition, even if the drainage in the supply passage is performed through the drainage passage after the previous mist operation, the drainage valve opening / closing switching operation is performed to make the mist in the specific passage area bordered by the drainage valve. It becomes possible to be surely filled with water.

According to the second aspect , the notification by the notification means can allow the user to grasp that the cleaning operation is automatically performed instead of being abnormal, and the relatively high temperature mist is ejected vigorously. Even if it becomes, it becomes possible to promote the avoidance so as not to be exposed to the mist by grasping it in advance.

On the other hand, according to the bathroom dryer with a mist function according to claim 3 or claim 4 , although a relatively high temperature mist is ejected during the cleaning operation of the mist device provided therewith, the mist is ejected from the nozzle. It can be brought into contact with the forced wind flow by the blower at the moment, and even if the user touches the mist by the active and forced mixing / diffusion with the air, the sensible temperature can be greatly lowered. .

In particular, according to the fourth aspect , in addition to the mixing / stirring by the contact with the forced air flow described above, the direction of the mist flow ejected from the nozzle is forcibly changed so as not to contact the human body reliably. Can be made to

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

  FIG. 1 shows a mist device 2 according to an embodiment of the present invention and a bathroom dryer 3 with a mist function to which a mist function is provided by providing the mist device 2 together. In this embodiment, it extends from the heat source device 4 as a heat source for heating / heating the water for mist in the mist device 2 and a heat source for heating / heating the circulating air in the bathroom in the bathroom dryer. The thing which employ | adopted the structure which shares the high temperature water for heating (heat medium) supplied through the warm water circulation system for heating is shown. Therefore, the present invention may be applied to a heat source other than such a heat medium (for example, an electric heater) as a heat source (heating source), or to those using separate heat sources. The present invention may be applied and is not limited. The illustrated bathroom dryer 3 is of a ceiling installation type that is fitted into the ceiling R1 of the bathroom space R (see FIG. 2), but is not limited to this, and is a wall-mounted installation type that is attached to the side wall R2 of the bathroom space R or the like. The present invention may be applied to the above. Details will be described below.

  The mist device 2 includes one or two or more arbitrary numbers (two in the illustrated example) of mist spray nozzles (spray ports) 5 and 5, and a water supply source (for example, a water pipe) outside the figure up to the nozzles 5 and 5. Etc.) and a liquid / liquid heat exchanger 7 as a heating means for heating the mist water in the middle of the supply path 6. Further, spray valves 62 and 62 which are also constituted by electromagnetic valves are interposed at the upstream side position of 5 of the supply passage 6. Further, a drainage passage 8 is branched from a supply passage 6 between the liquid / liquid heat exchanger 7 and each spray valve 62. The drainage passage 8 includes a drainage valve 81 and a vacuum breaker 82 constituted by electromagnetic valves. Is extended out of the plane. In FIG. 1, reference numeral 63 denotes a check valve, 64 denotes a strainer, and 65 denotes a governor, which are interposed in the supply passage 6 upstream of the water supply valve 61. Reference numeral 66 denotes a mist water temperature sensor for detecting the temperature of mist water. The mist water temperature sensor 66 is downstream of the liquid / liquid heat exchanger and upstream of the spray valves 62. 6 is disposed.

  The bathroom dryer 3 takes in the inside air of the bathroom space R and recirculates it, and a blower (circulation fan) 10 for circulating and blowing the inside air, and heating and raising the temperature of the taken inside air The heat dissipating heat exchanger 11 as a heating means is provided as a main component, and these are built in the housing 12. A main body grill 13 (see FIG. 3) on the lower surface side of the housing 12 is installed so as to be exposed from the bathroom ceiling R1 to the bathroom space R. The inside air circulation passage 9 sucks the inside air of the bathroom space R from the air suction port 131 of the main body grill 13 by the operation of the blower 10, and then passes through the outer surface side of the heat exchanger 11 for heat radiation and again from the opening of the louver 132. It blows out toward the bathroom space R. When the inside air passes through the outer surface side of the heat-dissipating heat exchanger 11, heat is received from the heat exchanger 11, and the inside air heated and heated by this heat release is returned to the bathroom space R. .

  The heat source unit 4 has a hot water circulation type hot water heating function, and circulates and supplies one or more heating terminals through a separate circulation path using hot water at a predetermined temperature heated by combustion heat as a heat source. It is. And as one of said heating terminals, the heat exchanger 11 for heat radiation of the bathroom dryer 3 is set, and also the liquid / liquid heat exchanger 7 of the mist device 2 is set as one of the heating terminals. . The downstream side of the hot water going-out passage 14 extended to supply the hot water for the heat source from the heat source unit 4 is branched into two, and one of them is radiated heat through a supply switching valve 141 constituted by a thermal valve. The other end of the exchanger 11 is connected to the inlet of the liquid / liquid heat exchanger 7 via a water proportional valve 142 having a closing function. Then, the outlet side of the liquid / liquid heat exchanger 7 and the outlet side of the heat radiating heat exchanger 11 are joined together, and the hot water having a low temperature after the heat exchange is returned to the heat source unit 4 through the hot water return passage 15. It is like that. When the supply switching valve 141 is opened, heat source hot water is supplied to the heat-dissipating heat exchanger 11 to enable heating of the inside air. When the supply switching valve 141 is closed, supply of the heat source hot water is shut off and the inside air is also heated. Will be stopped. On the other hand, the degree of opening of the water proportional valve 142 can be adjusted, and the degree of heating in the liquid / liquid heat exchanger 7 is changed by changing the degree of supply of hot water for heat source by adjusting the opening. ing. Further, when the water proportional valve 142 is fully closed, the supply of the hot water for the heat source is cut off, so that the heating of the mist water is also stopped. The code | symbol 143 in FIG. 1 is the hot water temperature sensor for heat sources which detects the temperature of the hot water for heat sources.

  The operation of the bathroom dryer 3 provided with the mist device 2 is controlled by the controller 16. The controller 16 is connected to the remote controller 161 and the heat source controller 41 of the heat source apparatus 4 in a wired or wireless manner so as to be communicable by wire or wirelessly, and various detection signals, commands or transmission information from the heat source apparatus 41, or remote control based on a preinstalled program. In response to an input signal from 161, various operation controls (control modes) are executed.

  For example, in the mist operation control mode, when the mist operation ON operation signal is output from the remote controller 161, first, the water supply valve 61 and the drain valve 81 are opened while all the spray valves 62 and 62 are closed to supply the supply passage 6. While supplying water, the water proportional valve 142 is opened to a predetermined opening to circulate and supply the hot water for the heat source to the liquid / liquid heat exchanger 7. When the temperature detected by the mist water temperature sensor 66 rises to a predetermined mist temperature, the drain valve 81 is closed and the spray valves 62 and 62 are opened. Thereby, the water for mist whose temperature has been raised is supplied to each nozzle 5 and sprayed toward the bathroom space R from each nozzle 5 as mist M. When a mist operation OFF operation signal is output from the remote controller 161 by a user operation, the water proportional valve 142 is fully closed, while the water supply valve 61 and the spray valves 62 and 62 are closed. At this time, the mist water remaining in the supply passage 6 downstream of the water supply valve 61 is drained by opening and closing the drain valve 81 and the like.

  Based on the above configuration, the cleaning operation control mode incorporated in the controller 16 in order to prevent clogging of each nozzle 5 and to eliminate clogging generated in each nozzle 5 will be described below.

  The outline of the process in the cleaning operation control mode is as follows. That is, first, the mist water is filled (filled) in the specific passage area S (see the area surrounded by the dotted line in FIG. 1) in the passage (in the pipe) of the mist device 2 by the valve opening / closing switching operation, and the mist water is filled. In this state, the specific passage area S is hermetically closed. The target of the valve opening / closing switching operation is the spray valves 62 and 62, the water supply valve 61 and the drain valve 81. Next, by controlling the opening of the water proportional valve 142, the hot water for heat source is introduced into the liquid / liquid heat exchanger to heat the mist water filled in the specific passage region S to a predetermined temperature. The internal pressure in the specific passage area is increased to a predetermined value by the expansion of. When the pressure is increased, the mist water in a pressurized state is supplied to the nozzles 5 and 5 and ejected from the nozzles 5 and 5. That is, by supplying high-pressure mist water to the nozzles 5 and 5 and ejecting it, the clogging is eliminated and the clogging is prevented, and the operation control of the components already provided with the high-pressure is performed, that is, the supply passage 6 It is obtained by switching operation control of the various valves 61, 62, 81 and the water proportional valve 142 intervening in the above, and the additional installation of special components is unnecessary only by adding the control mode. The specific passage region S in the present embodiment is the portion of the supply passage 6 from the water supply valve 61 to the spray valves 62 and 62 sandwiching the liquid / liquid heat exchanger 7 and the drainage to the drain valve 81 that is branched and communicated therewith. This is a portion of the passage 8. That is, it is a passage area that can be closed and closed by closing the three types of valves 61, 62, and 81.

  Next, the cleaning operation control mode will be described in detail with reference to FIGS. 4 and 5. When an execution command (details will be described later) of the cleaning operation control mode is output by, for example, turning on the cleaning operation switch of the remote controller 161, the control is started. First, the water supply valve is maintained while the spray valves 62 and 62 are kept closed. 61 and the drain valve 81 are opened (step S1), and this state is maintained until the set time α seconds elapses (NO in step S2). As a result, the feed water flows into the specific passage area S that has been drained after the mist operation in the previous stage through the open water supply valve 61, and the internal air passes through the open drain valve 81 and the drain passage 8. And the tip of the inflow water reaches the drain valve 81 position. The set time α seconds is a time required for the supply water to flow to the end of the specific passage area S and is filled. If α seconds have elapsed (YES in step S2), the drain valve 81 is first closed (step S3), and after a set time β seconds (for example, 0.5 seconds) for ensuring water filling, elapses. (YES in step S4), the water supply valve 61 is closed (step S5). Since the filling of water is almost completed after the elapse of α seconds in step S2, the drain valve 81 and the water supply valve 61 may be simultaneously closed instead of steps S3 to S5. Thus, the inside of the specific passage area S is closed and closed in a state where the water for mist is filled. Such steps S1 to S5 constitute the sealing control.

  Next, a circulation supply request command for the heat source hot water (heating hot water) is output to the controller 41 of the heat source unit 4 (step S6), and the heating operation of the heat source unit 4 is switched to ON control (for example, the side of the heat source unit 4) The heat valve is switched by the operation control on the heat source unit 4 side). Thereby, the hot water for the heat source can be supplied to the hot water going-out passage 14. Then, the water proportional valve 142 is opened (step S 7), the heat source hot water is introduced into the liquid / liquid heat exchanger 7 and circulated through the hot water return passage 15. The mist water in the specific passage region S is heated and heated by heat exchange heating with the hot water for the heat source introduced into the liquid / liquid heat exchanger 7, and the volume expands accordingly, and the internal pressure in the specific passage region S is increased. Will rise. Since the degree of the internal pressure increase is related to the temperature increase of the mist water, it can be grasped by monitoring the temperature increase of the mist water. Therefore, whether or not the increase in the internal pressure has been completed to a predetermined internal pressure value depending on whether or not the detected temperature of the water temperature sensor 66 for mist has reached a set temperature Tp that is set in advance by a test or the like as the internal pressure increase completion temperature. The heat exchange heating by the liquid / liquid heat exchanger 7 is continued until the detected temperature reaches the set temperature Tp or higher (NO in step S8).

  If the detected temperature reaches or exceeds the set temperature Tp (see point P in FIG. 5), that is, if the internal pressure in the specific passage area S has been increased to a predetermined internal pressure value (YES in step S8), the spray valve 62, 62 and the water supply valve 61 are opened (step S9). As a result, the water for mist with increased internal pressure is ejected as mist from the nozzles 5 and 5, and the scales that are likely to adhere to the inner surfaces of the nozzles 5 and 5, and the scales that have already adhered to the outside. Blow away. The mist ejection in step S9 is continued for a predetermined time in a range in which the temperature of the mist water does not exceed the mist excessive rise prevention temperature Tx (for example, 75 ° C.) as shown in FIG. The valve 142 may be closed. This completes the cleaning operation control. From the above step S6 to YES at step 8 constitutes the pressure increase control, and thereafter constitutes the ejection control.

  Even if the water supply valve 61 can be closed even if the water supply valve 61 is closed, the internal pressure rises with respect to the check valve 63 on the upstream side, even if the internal pressure is of a type that propagates to the upstream side. As a result, the check valve 63 can be completely shut off, and a specific passage region can be formed by the portion up to the check valve 63 so that the specific passage region can be closed and closed. .

  Such an execution command for the cleaning operation control mode may be output based on a user operation using the remote controller 161 as described above, or may be further automatically output. For example, if the mist operation is executed by the user, the cleaning operation control mode execution command may be automatically output every time the mist operation is performed, or the execution command may be periodically or every time the mist operation is executed. May be automatically output. For example, every time the mist operation is performed, the cleaning operation is performed before the start of the mist operation or at the end of the mist operation. For example, regularly means every 24 hours, every 48 hours, or every week. Further, every time the mist operation is executed is, for example, every five mist operations. Furthermore, when the non-execution period of the mist operation exceeds a predetermined setting period, an execution command may be output so that the cleaning operation is automatically executed before the next mist operation.

  Further, when the mist is ejected from each nozzle 5 in the cleaning operation control mode, the mist may become high temperature. Therefore, the blower 10 is forcibly controlled in conjunction with the mist ejection from each nozzle 5 to control the bathroom space. A wind flow may be forcibly formed in R, and the mist may be diffused by the wind flow. By doing so, even when the mist at the time of ejection from each nozzle 5 is at a high temperature, it is mixed with air positively by the above-described wind flow and diffused over a wide range at the moment when the mist is ejected from each nozzle 5. Therefore, even if the mist touches the user, the sensible temperature felt by the user can be significantly reduced.

  Furthermore, when the mist is ejected from each nozzle 5 in the cleaning operation control mode, the mist may be hot, so the direction of the mist ejected from each nozzle 5 is positively changed. Also good. When cleaning operation is performed, it is normal that the user is outside the bathroom, so it is not necessary to consider so much, but especially when the cleaning operation is executed before the start of the mist operation, the direction of the mist is changed. Is preferred. Specifically, as shown in FIG. 2, the blower 10 is forcibly operated in the same manner as described above, and the drive motor of the drive grille 132 of the main body grill 13 is controlled to rotate so as to have a predetermined cleaning mode angle. Thus, the mist flow may be forcibly changed so that the mist blown from each nozzle 5 by the wind blown from the bathroom dryer 3 flows toward the side wall R2 of the bathroom. In short, the cleaning mode angle may be set to a rotation angle at which the direction of the mist flow is forcibly changed toward a place where it is predicted that the user (human body) will not exist in the bathroom space R. Normally, the rotation angle for forcibly blowing the air flowing toward the side wall R2 near the ceiling to each nozzle 5 may be set as a fixed value.

  A specific example of the control will be described with reference to FIG. 6. If a mist operation ON operation command is output (YES in step S21), the louver 132 is rotated to the user set angle set by the user with the remote controller 161 or the like so far. If there is no start of cleaning operation control mode (output of execution command), this is continued (NO in step S23). In principle, if an execution command for the cleaning operation control mode is output (YES in step S23), the louver 132 is forcibly rotated to the cleaning mode angle (step S24), and this operation is continued until the cleaning operation is completed. The state is maintained (NO in step S25). When the cleaning operation is completed (YES in step S25), the louver 132 is rotated and moved to the user set angle as a rule to start the mist operation (step S26).

  In addition, the presence of a human body in the bathroom space R may be detected in addition to the fixed value as the cleaning mode angle, and another rotation angle value may be set according to the detection result. For example, when the user is outside the bathroom space R and the presence of a human body is not detected, the fixed value is set as a precaution, while when the user is inside the bathroom space R and the presence of a human body is detected, You may make it set the rotation angle which turned to the opposite side or different side from the position of the detected human body. What is necessary is just to use the following as a detection means which detects presence of said human body. For example, whether or not a human body exists in the bathtub can be grasped by the fluctuation state of the detection value of the water level sensor or the heartbeat detection of the human body using the heartbeat sensor installed in the bathtub, and the user exists in the bathroom space R. It can be grasped by detecting the entrance / exit by the infrared sensor at the entrance of the bathroom or the monitoring status by the image recognition device installed in the bathroom.

  Further, when the cleaning operation control mode is executed, the remote controller 161 or another remote controller such as a bathroom remote controller indicated by reference numeral 411 in FIG. , Voice guidance, warning lamp lighting / flashing, etc. about the fact that the cleaning operation is started by the user before the start of the control in the cleaning operation control mode, or that the cleaning operation is currently being performed during the execution of the control, Or you may make it alert | report by the character guidance display etc. with respect to a display part. In the case of the bathroom remote controller 411, a command signal may be output via the heat source controller 41. Alternatively, in addition to or in addition to these, a warning lamp may be turned on and blinking or a warning sound may be blown on the main body grill 13. For example, as shown in FIG. 3, a warning lamp (for example, LED) 134 and an alarm buzzer 135 are provided in the main grill 13 in addition to the operation lamp 133, and as a part of the control content of the cleaning operation control mode, During execution after the start, the warning lamp 134 may be turned on or blinking, or the alarm buzzer 135 may be sounded.

  The above-described cleaning operation control mode is not only used when newly installed in the controller 16 in advance in a factory or the like, but also for replacement / addition or overwrite installation of a board to a controller such as an existing mist device. It can be added later by execution or the like. Thereby, even if it is an existing mist apparatus etc., the effect by this invention can be acquired now.

<Other embodiments>
In addition, this invention is not limited to the said embodiment, Various other embodiments are included. That is, in the said embodiment, although the example which started control from the state by which the supply channel | path 6 was drained was shown, the state by which the water for mist is filled (filled) in the channel | path without draining in the previous step. If so, the spray valve 62, 62, the water supply valve 61, and the drain valve 81 are maintained in the closed state, and the specific passage region S is already in the closed state, so that the cleaning operation control mode includes the mist water filling and It is possible to omit the control for hermetically closing.

  Moreover, although said embodiment demonstrated the case where the mist apparatus 2 was attached to the bathroom dryer 3, it is not restricted to this, A mist apparatus can also be installed independently.
