  The present invention has been made in view of the above circumstances, and an object of the present invention is a bathroom heating dryer with a mist sauna function provided with a hot air outlet that gives freedom to a mist spray state and a dry state. It is.

In order to solve the above problems, the present invention provides a drying operation for drying the interior of the bathroom 2 by blowing warm air from the warm air outlet 3 while ventilating the interior of the bathroom 2, and the bathroom from the position near the hot air outlet 3. 2 is a bathroom heater / dryer with a mist sauna function capable of selecting a mist sauna operation in which water for mist sauna is sprayed toward the inside, wherein a mist nozzle 6 is provided in the vicinity of the hot air outlet 3 and A movable louver 4 is provided at the hot air outlet 3 to adjust the direction of the hot air. The movable louver 4 includes a plurality of vanes 4a and 4b arranged in parallel in the longitudinal direction of the hot air outlet 3, and each vane. Vane drive means 5 for changing at least one of the wind speed and the blowing position of the warm air from the warm air outlet 3 by individually closing the 4a, 4b, and the plurality of vanes 4a, 4b Wind blow 3, the vane driving means 5 is configured to include all the vanes 4a and 4b. The vane driving means 5 includes a central vane 4a disposed on the center side in the longitudinal direction of FIG. The standard wind speed operation mode in which the warm air is blown out from the entire warm air outlet 3 at the standard wind speed, and the vanes 4b are closed and the warm air is blown out only from the central side of the warm air outlet 3 to obtain the above-mentioned standard wind speed. a large wind velocity operation mode to obtain even greater wind speed, in any of the drying operation and a mist sauna operation are also features that you can execute switches.

With this configuration, during the drying operation, the vane 4a and 4b are arbitrarily opened and closed to control the spray range and speed of the hot air. On the other hand, when the mist sauna is operated, the mist is diffused into the bathroom 2 by taking warm air by opening the vanes 4a and 4b simultaneously with the mist spraying from the mist nozzle 6, but at this time, each vane 4a and 4b is arbitrarily set By opening and closing, the mist spraying range and speed can be controlled according to the taste of the mist sauna. In both drying operation and mist sauna operation, the standard wind speed operation mode and the large wind speed operation mode can be switched and executed, so the wind speed is switched appropriately according to the degree of drying or the preference of the mist sauna. Be free.

  In response to an operation start command from the remote controller, the large wind speed operation mode is executed, and an operation of automatically switching from the large wind speed operation mode to the standard wind speed operation mode after a predetermined time has elapsed since the start of operation is executed. Is preferred. In this case, in the drying operation, only the central vane 4a of the hot air outlet 3 is opened by the first large wind speed operation mode, and drying can be promoted by the large wind speed. After a predetermined time, the vane 4a is switched to the standard wind speed operation mode. , 4b can be opened so that warm air can be uniformly blown at the standard wind speed, so that the operation efficiency can be improved. On the other hand, at the start of mist sauna operation, the mist from the mist nozzle 6 can be quickly diffused in the bathroom 2 on the high wind speed by the first high wind speed operation mode. However, since it is easy to spread in the bathroom 2 by riding on warm air, a mist sauna space can be formed in a short time. After that, after a predetermined time has passed, the mode is switched to the standard wind speed operation mode, and all the vanes 4a and 4b are opened and heated. You can enjoy a comfortable mist sauna bath with the synergistic effect of wind and mist spray.

  In addition, a humidity sensor for detecting the humidity in the bathroom is provided, and the large wind speed operation mode is executed in response to the operation start command from the remote controller, and the detected value of the humidity sensor satisfies a predetermined condition after the operation is started. It is sometimes preferable to perform an operation of automatically switching from the high wind speed operation mode to the standard wind speed operation mode. In this case, in the drying operation, only the central vane 4a of the hot air outlet 3 is opened by the first large wind speed operation mode, and drying can be promoted by the large wind speed. When the detected value of the humidity sensor satisfies a predetermined condition, it is standard. By switching to the wind speed operation mode, all the vanes 4a and 4b are opened so that the warm air can be uniformly blown at the standard wind speed, so that the operation efficiency can be improved. On the other hand, at the start of mist sauna operation, the mist from the mist nozzle 6 can be quickly diffused in the bathroom 2 on the high wind speed by the first high wind speed operation mode. However, since it is easy to spread in the bathroom 2 by taking hot air, it is possible to form a mist sauna space in a short time, and then switch to the standard wind speed operation mode when the detection value of the humidity sensor satisfies a predetermined condition. The vanes 4a and 4b open, and you can enjoy a comfortable mist sauna bath with the synergistic effect of warm air and mist spray.

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

  FIG. 1 shows an example of a bathroom heating dryer 1 with a mist sauna function used in the embodiment of the present invention, and FIG. 2 shows an example of a hot air outlet 3 of the bathroom heating dryer 1.

  The bathroom heating / drying machine 1 is attached to the wall of the bathroom 2 and controls a heating / drying machine body for drying, exhausting and heating the bathroom 2, a mist spraying device for spraying mist in the bathroom 2, and these. It is comprised with a control part (not shown). The control unit selectively performs a drying operation and a mist sauna operation in response to a remote control signal instructed from a remote controller or a signal from a bathroom temperature sensor (not shown) that detects the bathroom temperature. In addition, since the technique currently disclosed by conventionally well-known Unexamined-Japanese-Patent No. 2008-1110021 can be used about the specific structure of a heating-dryer main body and a mist spraying apparatus, detailed description is abbreviate | omitted.

  As shown in FIG. 1 (b), a horizontally long hot air outlet 3 is provided on the lower surface of the equipment casing 1 a of the bathroom heater / dryer 1. FIG. 1B shows a fully opened state of the hot air outlet 3. A mist nozzle 6 for spraying hot water for a mist sauna into the bathroom 2 is provided in the vicinity of the hot air outlet 3. In this example, a plurality of mist nozzles 6 are provided at a position behind the hot air outlet 3 and below the hot air outlet 3, and the hot air blowing direction from the hot air outlet 3 intersects with the mist spraying direction. Thus, the mist is diffused in the bathroom 2 by the hot air.

  FIG. 2 shows an example of the movable louver 4 provided at the hot air outlet 3 of the bathroom heater / dryer 1.

  The movable louver 4 adjusts the direction of the warm air, and the movable louver 4 in this example includes three vanes 4a and 4b arranged in parallel in the longitudinal direction of the warm air outlet 3, and each vane 4a. , 4b are individually opened and closed, and vane drive means 5 for changing at least one of the wind speed and the blowing position of the hot air from the hot air outlet 3 is configured.

  Here, the three vanes 4a and 4b are composed of one central vane 4a disposed on the center side in the longitudinal direction of the hot air outlet 3 and two both end sides disposed on both ends in the longitudinal direction. It consists of vane 4b.

  The vane driving means 5 includes a first motor 5a that drives the central vane 4a and a second motor 5b that simultaneously drives both end side vanes 4b in the same direction. The first motor 5a and the second motor 5b are remotely operated in response to a command from the remote controller.

  The remote controller is standard from the heating operation switch that commands the heating operation, the ventilation operation switch that commands the ventilation operation, the drying operation switch that commands the drying operation, the mist sauna operation switch that commands the mist sauna operation, and the large wind speed operation mode An automatic operation course selection switch for automatically switching to the wind speed operation mode is provided.

  In the standard wind speed operation mode, the first motor 5a and the second motor 5b are driven to open all the three vanes 4a and 4b, thereby opening the entire warm air outlet 3 and a predetermined wind speed (hereinafter referred to as standard wind speed). The warm air is blown out (state shown in FIG. 4). In the large wind speed operation mode, the first motor 5a is driven to open only the central vane 4a, so that the warm air is larger than the standard wind speed only from the center side of the warm air outlet 3 (hereinafter referred to as large wind speed). (The state of FIG. 3). Further, in this example, a both-end blowing operation mode in which only the both-end vanes 4b are opened by driving the second motor 5b is provided, and in this both-end blowing operation mode, hot air is blown out only from both ends of the hot air outlet 3. (State of FIG. 5).

  Next, an example of the operation will be described.

  At the time of drying operation, as shown in FIG. 1 (a), under the movable louver 4, a thick clothing that is difficult to dry is hung in the center, and a thin clothing that is easy to dry is suspended on both sides. Press the switch. When the automatic operation course is selected at this time, the high wind speed operation mode is executed first, and only the central vane 4a of the hot air outlet 3 is opened (the state shown in FIGS. 3A and 3B). Drying is promoted by intensively hitting hot air at high wind speed toward difficult thick clothing. Thereafter, when a predetermined time elapses, the mode is automatically switched to the standard wind speed operation mode, all the vanes 4a and 4b are opened, and warm air is uniformly blown to the respective clothes at the standard wind speed (FIGS. 4A and 4B). State). Thereby, each clothing is in an even dry state, and unevenness in the degree of drying of the clothing can be reduced. By the way, if the drying operation is performed until the clothes are completely dried, assuming that clothes that are easy to dry are mixed, an unnecessary drying operation is performed. Becomes longer and also consumes more power, hindering energy saving. On the other hand, in this example, the high wind speed operation mode and the standard wind speed operation mode are sequentially performed, so that hot air is concentrated on clothes that are difficult to dry and unnecessary warm air is not applied to clothes that are easy to dry. Therefore, driving efficiency can be increased.

  Here, FIG. 6A is experimental data showing a drying situation when the standard wind speed operation mode is performed. Here, under an outside air temperature of 30 ° C., 2 kg of the test cloth in the bathroom 2 was wetted with water and a drying operation was performed. A line L1 in FIG. 6A shows a change in the drying rate (%) with time. Line L2 is a temperature change in the bathroom 2. FIG. 6B is a graph showing the relationship between the absolute humidity in the bathroom 2 detected by a humidity sensor (not shown) for detecting the humidity in the bathroom and the elapsed time, and the equilibrium line L4a of the line L4 represents the bathroom. The humidity in 2 indicates an equilibrium state, and in this equilibrium state, it is possible to dry to some extent. By the descending line L4b that is no longer in equilibrium, the clothes (test cloth that is difficult to dry) concentrated and dried at the beginning of operation start. It can be seen that the drying proceeds.

  On the other hand, during mist sauna operation, the mist sauna operation switch on the remote controller is pressed. When the automatic course is selected at this time, the mist M is sprayed from the mist nozzle 6 and, at the same time, only the central vane 4a of the hot air outlet 3 is opened by the first high wind speed operation mode (the state shown in FIG. 3C). The mist M can be quickly diffused in the bathroom 2 by riding on the wind speed, and the mist M is easily filled in the bathroom 2. Therefore, even if the mist M is a spot mist sprayed in a spot manner, it is easy to spread in the bathroom 2 by taking hot air, so that a mist sauna space can be formed in a short time. It automatically switches to the operation mode, and all the vanes 4a and 4b are opened (the state shown in FIG. 4C), and a comfortable mist sauna bath can be enjoyed by the synergistic effect of warm air and mist spray. In addition, the mist experience can be changed by changing the wind speed and the blowing position.

  Further, during this mist sauna operation, it is possible to select a both-end blowing operation mode in which only the both-end vanes 4b are opened. In this case, since the mist M is sprayed only from both sides of the hot air outlet 3 (the state shown in FIGS. 5A and 5B), the mist M can be prevented from hitting a person who does not want to take the mist M directly. The comfort can be kept intact.

  Further, as another example of operation during the mist sauna operation, the standard wind speed operation mode may be first executed, and control to automatically switch to the high wind speed operation mode after a predetermined time has elapsed may be performed. In this case, the entire bathroom 2 can be warmed by first spraying mist uniformly in the bathroom 2 at a standard wind speed. You can experience soft mist while taking a bath, and after the bather takes a bath, you can switch to the high wind speed operation mode to experience a mist that is spot-like and stimulating with a large air volume. .

  As another example of operation during mist sauna operation, the high wind speed operation mode is first executed, and when the detected value of the humidity sensor satisfies a predetermined condition after the operation starts, the standard wind speed operation mode is automatically set. Control for switching may be performed. When the detection value of the humidity sensor satisfies a predetermined condition, for example, the state indicated by the equilibrium line L4a in FIG. 6B has shifted to a state where the humidity indicated by the descending line L4b decreases. When (ie, the boundary between the equilibrium line L4a and the descending line L4b), when the detected value is less than or less than a predetermined value, or when the rate of decrease of the detected value is less than or less than a predetermined value , Etc. In this case, in the drying operation, only the central vane 4a of the hot air outlet 3 is opened by the first large wind speed operation mode, and drying can be promoted by the large wind speed. When the detected value of the humidity sensor satisfies a predetermined condition, it is standard. By switching to the wind speed operation mode, all the vanes 4a and 4b are opened so that the warm air can be uniformly blown at the standard wind speed, so that the operation efficiency can be improved. On the other hand, at the start of mist sauna operation, the mist from the mist nozzle 6 can be quickly diffused in the bathroom 2 on the high wind speed by the first high wind speed operation mode. However, since it is easy to spread in the bathroom 2 by taking hot air, it is possible to form a mist sauna space in a short time, and then switch to the standard wind speed operation mode when the detection value of the humidity sensor satisfies a predetermined condition. The vanes 4a and 4b open, and you can enjoy a comfortable mist sauna bath with the synergistic effect of warm air and mist spray.

  According to the above configuration, the vanes 4a and 4b that close the movable louver 4 of the hot air outlet 3 are divided into three, and opening and closing control is performed for each of the vanes 4a and 4b to change at least one of the wind speed and the blowing position of the hot air. By making it, a freedom degree can be given to a dry state and a mist spraying state. In other words, during the drying operation, the high wind speed operation mode and the standard wind speed operation mode are appropriately selected according to the thickness and dryness of the clothes to be dried, and the vanes 4a and 4b are driven to open and close, thereby spraying warm air. The range and speed can be controlled, and unevenness in the degree of drying of clothes can be reduced by making the wind speed distribution different according to clothes that are easy to dry and clothes that are difficult to dry. On the other hand, during mist sauna operation, the vanes 4a and 4b are driven to open and close by appropriately selecting the large wind speed operation mode and the standard wind speed operation mode (or both-end blowing operation mode) according to the mist sauna of choice at the same time as mist spraying. By doing so, the spraying range and speed of mist can be controlled, and a favorite mist sauna space can be formed in a short time.

  In the above embodiment, the case where the vanes 4a and 4b are divided into three is illustrated, but the number of vanes is not limited to three.

  The bathroom heater / dryer 1 with a mist sauna function of the present invention is not limited to the wall-mounted type shown in FIG.
