Description

  The present invention relates to a hot water supply direct connection type mist device in which mist water heated by a heat source device having a hot water supply function is ejected from a mist nozzle into a room through a mist water channel.

  Conventionally, devices that can easily enjoy a mist bath in a bathroom at home have been sold. As this type of device, for example, there are a type installed on the ceiling of a bathroom (hereinafter referred to as “ceiling installation type”), a type fixed on a bathroom wall (hereinafter referred to as “wall hanging type”), and the like. Further, as means for generating mist, for example, hot water heated by a heat source device having a hot water supply function is jetted as it is from a mist nozzle through a mist water channel (hereinafter referred to as “hot water supply direct connection type”). Or heat exchange is performed between high-temperature heating hot water (for example, 80 ° C.) sent from the heat source device by the heat exchanger in the equipment and the feed water to heat the feed water, and this heated feed water is ejected from the mist nozzle in a mist form. (Hereinafter referred to as “warm water circulation type”). Under such circumstances, a hot water circulation type mist device described in, for example, Patent Document 1 has been widely used for both the ceiling-mounted type and the wall-mounted type.

  The mist device of Patent Document 1 includes a door sensor that detects the open / closed state of the bathroom door, and stops the mist operation when the door sensor detects the open state of the bathroom door. This prevents water droplets from leaking out of the room.

JP 2001-204788 A

  For example, when it is desired to use the hot water circulation type mist device as described in Patent Document 1 in a house that is not provided with piping, heat exchangers, or the like for circulating high-temperature heating hot water, the pipes, heat exchangers, etc. are newly provided. Therefore, the cost associated with the installation increases and the size of the apparatus increases.

  On the other hand, if a hot water supply direct connection type mist device is adopted, heat exchange between the high-temperature heating hot water and the water supply can be omitted, so the installation cost of piping and heat exchangers can be reduced, and the device size can be made compact. . In addition, since hot water can be used directly, a large amount of mist is generated and a bathroom heating function can be expected. On the other hand, since the amount of mist generation is large, the amount of water droplet leakage when the bathroom door is opened tends to increase. In order to prevent this, it may be possible to stop the mist operation by detecting the open state with a door sensor as in the past, but it is necessary to newly install a door sensor on the bathroom door. Can not enjoy the mist bath because it drops rapidly.

  Therefore, it is desired to simply configure a hot water supply directly-coupled mist device that can reduce the inconvenience of water droplets leaking outside the room and suppress a decrease in indoor humidity.

  The characteristic configuration of the hot water supply direct connection type mist device according to the present invention includes a mist nozzle directed indoors, and water for mist heated by a heat source device having a hot water supply function passes through the mist nozzle from the mist nozzle. A hot water supply direct-coupled mist device that is jetted toward the mist, a flow rate regulator that adjusts a flow rate per unit time of the mist water flowing through the mist channel, a temperature measurement unit that measures the temperature in the room, and A humidity measuring unit that measures the humidity in the room; and a control unit that controls the operation of the flow controller, wherein the control unit has a decrease in the measured temperature of the temperature measuring unit equal to or greater than a first predetermined value; When the amount of decrease in the measured humidity of the humidity measuring unit is equal to or greater than a second predetermined value, the amount of mist water ejected is reduced.

  Since the hot water supply directly connected mist device as in this configuration can directly use hot water supplied to the bathtub, the amount of mist generated is large, and even when the door is opened, the room humidity is maintained at a certain level. On the other hand, the amount of water droplet leakage when the door is opened is relatively large.

  Therefore, in this configuration, determination is made using the principle that the temperature and humidity in the room decrease when the door is opened, and the amount of mist water ejected is reduced if the door is open. As a result, the amount of water droplet leakage when the door is opened can be reduced. Moreover, since the mist operation is not stopped, the humidity in the room is maintained to some extent, and the user can comfortably enjoy the mist bath.

  Further, if the open state of the door is determined based on the indoor temperature and humidity as in the present configuration, the component configuration already built in the apparatus is sufficient, so that cost can be saved and the determination method is simple. In particular, in this configuration, the humidity in the room may be lowered by ventilation or the like, so the amount of decrease in the room temperature is also grasped at the same time to improve the determination accuracy in the open state of the door. Thus, the inconvenience of water droplets leaking out of the room was reduced, and a hot water supply directly connected mist device capable of suppressing a decrease in indoor humidity could be simply configured.

  Preferably, the control unit increases the amount of mist water ejected when the amount of increase in the measured humidity of the humidity measuring unit becomes equal to or greater than a third predetermined value after decreasing the amount of mist water ejected. It is.

  As described above, since the mist operation is not stopped even when the door is open, the humidity in the room increases when the door is subsequently closed. Since the door is opened and closed in a relatively short time, the influence of other external factors that lower the humidity in the room is extremely small. Therefore, in this configuration, it is determined that the door is closed only by the amount of increase in indoor humidity, and the amount of mist water ejected is increased. As a result, erroneous determination of the control unit can be prevented and the normal mist operation can be smoothly restored.

  In addition, it is preferable that the control unit includes a temperature adjustment unit that adjusts the indoor temperature based on the temperature measured by the temperature measurement unit.

  If a temperature control unit like this configuration is provided, the room temperature can be maintained at the target temperature even if the door is opened and closed, so the user can take a mist sauna bath (a warm room mist bath). You can enjoy comfortably. On the other hand, as described above, when the door is changed from the open state to the closed state and the mist water ejection amount is increased to return to the normal operation, the indoor temperature is adjusted to the target temperature. It is difficult to determine whether or not the temperature has increased due to the closing. However, in the above-described determination method, since the return determination is performed only with the indoor humidity, the user can continue to enjoy the mist sauna bath without erroneous determination.

  In addition, the control unit performs a process of reducing the amount of mist water to be ejected for a second predetermined time when the first predetermined time has elapsed after the measured humidity of the humidity measuring unit reaches 100%. When it is not executed, it is preferable to stop the mist water ejection.

  If the user feels too much about the mist sauna bath, the physical condition may be lost. Therefore, in this configuration, when the first predetermined time has elapsed since the room reached the maximum humidity, and when the door opening operation for performing the mist ejection reduction process is not performed continuously for the second predetermined time, The mist operation is to be stopped. As a result, the user can expect a deterrent effect against “hot flashes” and “hot flashes” without excessively experiencing the mist sauna bath.

It is a schematic diagram which shows the structure of a mist apparatus. It is a figure which shows the temperature at the time of normal driving | operation, humidity, and the amount of mist ejection. It is a figure which shows the temperature at the time of opening and closing of a bathroom door, humidity, and the amount of mist ejection. It is a flowchart which shows operation | movement of a mist apparatus. It is a schematic diagram which shows the structure of the mist apparatus which shows another embodiment.

  The hot water supply directly-coupled mist device according to the present invention is configured so that a user can easily enjoy mist sauna bathing indoors. Hereinafter, the mist apparatus 100 of this embodiment is demonstrated. FIG. 1 schematically shows the configuration of the mist device 100.

  The mist device 100 includes a plurality of mist nozzles 2 directed indoors, and mist water supplied through the mist water channel 3 is ejected from the mist nozzle 2 toward the room. The room is a space where you can enjoy mist sauna bathing, for example, the inside of the bathroom Y. The mist nozzle 2 is a spout that ejects mist water toward the inside of the bathroom Y. Mist water heated by the heat source device 1 is supplied to the mist nozzle 2 via the mist water channel 3.

  In the following, a so-called “ceiling installation type” mist device 100 which is a “hot water supply direct connection type” in which hot water heated by the heat source apparatus 1 is directly jetted from the mist nozzle 2 in the form of a mist is installed on the back of the ceiling of the bathroom Y. An example will be described. The heat source device 1 according to the present embodiment also has a hot water supply function for supplying hot water to the bathtub X, the shower Xa, the currant Xb, and the like, and the mist channel 3 is a hot water supply pipe that connects the heat source device 1 to the bathtub X and the like. (Not shown) may be branched, or may be provided independently of the hot water supply pipe. The hot water supply direct mist device 100 can use hot water directly compared to the hot water circulation mist device, and therefore has a large amount of mist ejection and can be expected to warm the bathroom Y.

  The heat source device 1 includes a first heat exchange mechanism 31 and a second heat exchange mechanism 32. The first heat exchange mechanism 31 includes a first heat exchange unit 41, a first combustor 42, and a first proportional valve 43. The second heat exchange mechanism 32 includes a second heat exchange unit 44, a second combustor 45, and a second proportional valve 46.

  When the flow rate of mist water flowing through the water supply channel 48 reaches a predetermined flow rate, the first proportional valve 43 and the on-off valve 47 are opened, and fuel (for example, gas) is supplied to the heat source unit 1. Thus, the first combustor 42 starts operation, and the mist water flowing through the water supply channel 48 is heated in the first heat exchange unit 41. The mist water heated in this way flows through the mist water channel 3 described above. In addition, it is good to detect whether the flow rate of the mist water flowing through the water supply channel 48 is a predetermined flow rate by a flow rate sensor 49 described later, and the temperature of the mist water heated by the first heat exchange unit 41 is the hot water supply temperature sensor 50. It is good to detect by.

  On the other hand, when the air heating heat exchanger 95 described above is operated, the second proportional valve 46 is opened while the heat medium in the heat medium circulation path 51 is circulated by the pump P. Accordingly, the second combustor 45 starts operation, and the heat medium flowing through the heat medium circulation path 51 is heated in the second heat exchange unit 44. The heat medium heated in this way is supplied to the air heating heat exchanger 95. In order to control the flow of the heat medium in the heat medium circulation path 51, it is preferable to provide a control valve 52.

  As shown in FIG. 1, the mist device 100 includes a main body casing 90 installed on the back side of the ceiling Ya of the bathroom Y and a grill plate 91 installed on the front side of the ceiling Ya of the bathroom Y.

  A plurality of mist nozzles 2, a flow sensor 49, a circulation fan 94, an air heating heat exchanger 95, a ventilation fan 96, a movable louver 97, and the like are provided inside the main body casing 90. Are provided with a temperature sensor 53 (an example of a temperature measurement unit) and a humidity sensor 54 (an example of a humidity measurement unit).

  The plurality of mist nozzles 2 are ejection means for ejecting mist water supplied through the mist water channel 3 into the bathroom Y in a mist form. The flow rate sensor 49 is a flow rate measuring means for measuring the flow rate of the mist water flowing through the mist channel 3. The circulation fan 94 is a circulation means that sucks air inside the bathroom Y through the suction port 92 formed in the grill plate 91 and blows the sucked air through the air passage 93 toward the inside of the bathroom Y. The air heating heat exchanger 95 is an air heating means for heating the air ventilated by the circulation fan 94. The ventilation fan 96 is a ventilation means that sucks air inside the bathroom Y through the suction port 92 and discharges it to the outside. The movable louver 97 is air blowing changing means for changing the blowing direction of the air blown from the air blowing path 93.

  The temperature sensor 53 is composed of a thermistor or the like having a non-contact sensor element, and is installed in the suction port 92 in order to measure the temperature of the air sucked by the circulation fan 94. The humidity sensor 54 is configured by a capacitance humidity sensor or the like in which the capacitance between the electrodes of the sensor element changes, and is installed in the suction port 92 in order to measure the humidity of the air sucked by the circulation fan 94. ing. That is, the temperature sensor 53 and the humidity sensor 54 measure the temperature and humidity inside the bathroom Y with the suction port 92.

  The mist device 100 according to the present embodiment includes an operation remote controller L provided outside the bathroom Y, a flow control valve 10 (an example of a flow controller), and a control unit 11.

  The operation remote control L is provided, for example, on the outer wall of the bathroom Y in which the dressing room is partitioned, and at least a “mist” button that allows the user to instruct the start and stop of the mist operation, and the user to operate and stop the bathroom heating. In addition, it has a “bathroom heating” button that can instruct the temperature setting. In the present embodiment, it is preferable to provide a mist sauna function in which when the “mist” button is pressed, the air heating heat exchanger 95 is operated to automatically start bathroom heating. When the temperature of the bathroom Y is high, such as in summer, the operation of the air heating heat exchanger 95 may be stopped and the air heating means of the mist device 100 may be omitted.

  Further, another operation remote controller (not shown) that can set the hot water supply temperature such as the shower Xa or the currant Xb is provided in a living room or a kitchen, for example. In this embodiment, the hot water supply temperature of the shower Xa, the currant Xb, or the like set by another operation remote controller is configured to be the set temperature of mist water. In addition, the other operation remote control which can set hot-water supply temperature may be unified to the operation remote control L provided in the outer wall of the bathroom Y, and it is not specifically limited.

  The flow rate adjusting valve 10 adjusts the flow rate per unit time of the mist water flowing through the mist water channel 3. The mist water channel 3 is a pipe through which the heat source device 1 and the mist nozzle 2 communicate with each other and mist water flows. The "flow rate per unit time" is the flow rate of mist water that flows through the mist channel 3 for a predetermined time (for example, 1 minute). In this embodiment, a maximum of 3.5 L / min can be circulated. It is. Such a flow rate adjusting valve 10 is preferably constituted by a linear valve whose flow path area can be changed linearly so that the mist water flowing through the mist water channel 3 can be adjusted to a desired flow rate. The opening degree of the flow rate control valve 10 may be feedback controlled based on the measured flow rate of the flow rate sensor 49 so that the flow rate of the mist water flowing through the mist water channel 3 becomes a desired flow rate.

  The controller 11 controls the operation of the flow rate adjustment valve 10 based on the detection values of the temperature sensor 53 and the humidity sensor 54. The operation of the flow rate adjusting valve 10 is a change operation of the flow path area (opening) of the flow rate adjusting valve 10 for adjusting the flow rate of the mist channel 3 as described above. Further, the controller 11 adjusts the amount of air heated by the air heating heat exchanger 95 by adjusting the output of the circulation fan 94 based on the measured temperature of the temperature sensor 53, and the temperature of the bathroom Y It is preferable to have a temperature adjustment unit that approaches the set temperature. The control unit 11 is configured by hardware, software for executing various processes, software having a memory as a core, or cooperation of hardware and software.

  As described above, in the mist device 100, the mist water heated in the heat source device 1 is supplied to the mist nozzle 2 via the mist water channel 3, and the mist water is ejected from the plurality of mist nozzles 2 in the form of mist. . When starting the ejection of mist water from the plurality of mist nozzles 2, the control unit 11 sets the flow rate control valve 10 so that the flow rate of the mist water flowing through the mist water channel 3 becomes equal to or higher than the first flow rate over a predetermined time. Set to 1 opening. The first flow rate is a flow rate that is equal to or higher than a flow rate at which the combustor connected to the upstream side of the mist water channel 3 (the first combustor 42 described above) can start operation. Here, the first combustor 42 is provided with safety measures so as not to ignite below a predetermined flow rate in order to prevent accidents such as idling. Therefore, the control unit 11 temporarily sets the flow rate of the mist water flowing through the mist water channel 3 to be equal to or higher than the flow rate at which the operation of the first combustor 42 is started, and at a time when the operation of the first combustor 42 is not stopped. The operation of the flow control valve 10 is controlled so as to maintain the first flow rate.

  At this time, since the mist device 100 according to the present embodiment can directly use hot water, the amount of mist generated is large, and even when the bathroom door is opened, the humidity of the bathroom Y is maintained to a certain degree. On the other hand, the amount of water droplet leakage when the bathroom door is opened is relatively large.

  Therefore, when the amount of decrease in the measured temperature of the temperature sensor 53 is equal to or greater than the first predetermined value and the amount of decrease in the measured humidity of the humidity sensor 54 is equal to or greater than the second predetermined value, the control unit 11 opens the flow control valve 10 in the first state. It is set as the 2nd opening degree smaller than a degree, and it is set as the structure which decreases the amount of ejection of mist water. That is, the open state of the bathroom door is determined based on the temperature and humidity of the bathroom Y, and when the bathroom door is in the open state, the amount of mist water ejected is reduced. As a result, the amount of water droplet leakage when the bathroom door is opened can be reduced. And since a mist driving | operation is not stopped, the user can enjoy a mist sauna bath comfortably, without the humidity of the bathroom Y falling rapidly. In particular, in the present embodiment, in view of the fact that the humidity in the bathroom Y also decreases due to ventilation or the like, the amount of decrease in the temperature of the bathroom Y is also grasped at the same time, thereby improving the determination accuracy in the open state of the door.

  FIG. 2 shows the temperature, humidity, and mist ejection amount of the bathroom Y during normal mist sauna operation. When the mist sauna operation is started, the temperature and humidity of the bathroom Y both increase, the humidity reaches 100%, and the temperature reaches the set temperature input by the operation remote controller L with a slight delay. Thereafter, the humidity is maintained at 100% unless the output of the ventilation fan 96 is increased, and if the temperature is slightly lowered due to the gap in the bathroom Y or ventilation, the controller 11 adjusts the output of the circulation fan 94 to heat the air. Control is performed to increase or decrease the amount of air heated by the heat exchanger 95 and return it to the set temperature. At this time, the mist ejection amount is maintained at the first flow rate. Note that the mist ejection amount may be varied from the first flow rate for humidity adjustment and temperature adjustment, and is not particularly limited.

  FIG. 3 shows the temperature, humidity, and mist ejection amount of the bathroom Y when the bathroom door is opened and closed. When the bathroom door is opened, the humidity and temperature of the bathroom Y decrease. At this time, the amount of decrease in the temperature of the bathroom Y increases compared to that during normal operation, and the humidity of the bathroom Y starts to decrease from the state where 100% is maintained. Therefore, the first predetermined value for determining the temperature decrease amount used in the control unit 11 is set larger than the decrease amount during normal operation, and the second predetermined value for determining the humidity decrease amount is set to a value larger than zero. ing. Since the first predetermined value and the second predetermined value may vary depending on the set temperature and the actual humidity state, they may be mapped based on experimental data.

  Subsequently, when the bathroom door is closed, the temperature of the bathroom Y gradually returns to the set temperature, and the humidity of the bathroom Y starts to increase and returns to 100%. On the other hand, the temperature of the bathroom Y is difficult to distinguish from the gradient that shifts in the increasing direction by heating during normal operation as described above. Therefore, the control unit 11 of the present embodiment opens the flow rate control valve 10 at the first opening when the amount of increase in the measured humidity of the humidity sensor 54 becomes equal to or greater than the third predetermined value after reducing the amount of mist water ejected. In this case, the amount of mist water ejected is increased to shift to normal operation. That is, by making a determination without using the temperature measured by the temperature sensor 53, an erroneous determination of the control unit 11 can be prevented, and the normal mist operation can be smoothly restored. The third predetermined value for determining the amount of increase in humidity is set to a value greater than zero.

  In addition, the control unit 11 performs the process of reducing the amount of mist water ejected for the second predetermined time when the elapsed time T after the humidity measured by the humidity sensor 54 has reached 100% has passed the first predetermined time. When it is not performed over a long period of time, it is preferable to stop the ejection of water for mist. In other words, when the first predetermined time has elapsed since the bathroom Y reached the maximum humidity, and when the door opening and closing resulting from the process of reducing the mist ejection amount has not been performed continuously for the second predetermined time, the mist operation is performed. Is going to be stopped. As a result, the user can expect a deterrent effect against “hot flashes” and “hot flashes” without excessively experiencing the mist sauna bath. Therefore, the user can enjoy the mist sauna bath comfortably. The first predetermined time and the second predetermined time may be configured to be set by the user, or may be registered in advance. Further, this mode may be configured to be selectable by the operation remote controller L.

  Next, the control method of the mist apparatus 100 with respect to the opening / closing operation | movement of a bathroom door is demonstrated using the flowchart of FIG.

  When the mist operation start button of the mist device 100 is pressed on the operation remote control L (Yes determination at # 11), instruction information indicating that there is an instruction to start mist operation is transmitted to the control unit 11. Next, the operation of the heat source unit 1 is started (# 12), the flow rate control valve 10 is set to the first opening, and the mist water is ejected at the first flow rate (# 13). Next, it is determined whether the temperature of the bathroom Y is within a predetermined range of the set temperature input to the operation remote controller L. If it is not within the predetermined range (# 14 NO determination), the output of the circulation fan 94 is adjusted to adjust the air. Control is performed to increase or decrease the amount of air heated by the heating heat exchanger 95 to return to the set temperature (# 15).

  On the other hand, when the temperature of the bathroom Y is within a predetermined range of the set temperature (# 14 Yes determination), the amount of decrease in the measured temperature of the temperature sensor 53 is equal to or greater than the first predetermined value and the amount of decrease in the measured humidity of the humidity sensor 54 is the first. 2. It is determined whether or not it is greater than or equal to a predetermined value (# 16). When the decrease amount of the temperature and humidity of the bathroom Y is smaller than the first predetermined value and the second predetermined value (# 16 NO determination), it is determined again whether the temperature of the bathroom Y is within the predetermined range of the set temperature (# 14). ). On the other hand, when the amount of decrease in temperature and humidity is equal to or greater than the first predetermined value or the second predetermined value (# 16 Yes determination), it is determined that the bathroom door has been opened, and the flow rate control valve 10 is set to a second smaller than the first opening. The opening is set to reduce the amount of water for mist ejection (# 17).

  Next, it is determined whether or not the increase amount of the humidity measured by the humidity sensor 54 has become a third predetermined value or more (# 18). When the amount of decrease in humidity is equal to or greater than the third predetermined value (# 18 Yes determination), it is determined that the bathroom door is closed, the flow control valve 10 is returned to the first opening, and the amount of mist water ejected is increased (# 19). Next, whether the elapsed time T from when the humidity measured by the humidity sensor 54 has reached 100% has passed the first predetermined time, and the process of reducing the amount of mist water jetted is not performed for the second predetermined time. It is determined whether or not (# 20). If the bathroom door has not opened and closed for a long time (# 20 Yes judgment), the mist sauna operation is stopped (# 21). If it has not passed for a long time (# 20 Nо judgment), return to # 14 to open and close the door. The determination is repeated.

  Hereinafter, only a different configuration from the above-described embodiment will be described in another embodiment. In addition, in order to make an understanding of drawing easy, it demonstrates using the same name and code | symbol to the same member.

The flow rate may be controlled by changing the number of locations of the mist nozzle 2 to be performed. Here, “branch at least into the first water channel 61 and the second water channel 62” means that the mist water channel 3 may be divided into three or more water channels. A first on-off valve 63 is provided in the first water passage 61 and communicates with the first mist nozzle 2A, and a second on-off valve 64 is provided in the second water passage 62 and communicates with the second mist nozzle 2B.

Mist water is spouted out. On the other hand, when the control unit 11 sets the mist water ejection amount to a second flow rate lower than the first flow rate when the bathroom door is opened, only the first mist nozzle 2A is closed by closing the second on-off valve 64. The water for mist is spouted from.

  The first mist nozzle 2A ejects mist water toward the washing area Y1 of the bathroom Y, and the second mist nozzle 2B ejects mist water toward the inner wall Y2 of the bathroom Y. Also good.
