JP 2009-60984 A

  However, in the conventional mist sauna device, the hot water sprayed from the hand grip in the bathtub is cooled in the bathtub to form water droplets, and it is difficult to reach the entire bathroom. Therefore, it has been difficult for the conventional mist sauna device to effectively humidify and raise the temperature in the bathroom.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a mist sauna device that can efficiently make a mist sauna state by effectively utilizing a narrow bathroom space.

The present invention has the following configuration.
(1) In a mist sauna apparatus that is installed in a bathroom in which a laundry basket is installed and sprays hot and cold water from a nozzle to increase the humidity and temperature of the bathroom, a plurality of the nozzles are attached to the laundry basket, and the laundry basket However, a flow path for supplying the hot and cold water to each of the nozzles is formed inside, and the flow path includes a main flow path formed in a longitudinal direction of the laundry basket, and a main flow path. A branch channel that branches and connects to the nozzle, wherein the main channel has a downstream channel cross-sectional area smaller than an upstream channel cross-sectional area .
Here, hot water refers to hot water or cold water.

(2) In the invention described in (1), the nozzle is rotatably attached to the laundry basket.

(3) In the invention described in (2), a fixed-side nozzle receiving portion that is fixed to the laundry basket and has a fixed-side communication path that communicates with the flow path, and is rotatably attached to the fixed-side nozzle receiving portion. The nozzle is mounted at a position deviated from the center in a posture to spray hot water obliquely downward, and has a rotary side nozzle receiver having a rotary side communication path for supplying hot water supplied from the fixed side communication path to the nozzle. And a portion.

(4) In a mist sauna device that is installed in a bathroom in which a laundry basket is installed and sprays hot water from a nozzle to increase the humidity and temperature of the bathroom , a plurality of the nozzles are attached to the laundry basket, The laundry basket has a flow path formed by supplying the hot water and the water to each of the nozzles, and a fixed side having a fixed communication path fixed to the laundry basket and communicating with the flow path. A nozzle receiving portion, and the nozzle is attached at a position offset from the center in a posture to spray hot water obliquely downward, and has a rotation side communication passage for supplying hot water supplied from the fixed side communication passage to the nozzle. A rotation-side nozzle receiving portion; and a shaft that rotatably attaches the rotation-side nozzle receiving portion to the fixed-side nozzle receiving portion. When the hot water is supplied to the nozzle and the hot water is sprayed from the nozzle, a force acts on the nozzle in a direction deviated from the center of the rotation side nozzle receiving portion, and the force passes through the nozzle. The nozzle rotates by acting on the rotation side nozzle receiving portion and rotating the rotation side nozzle receiving portion with respect to the fixed side nozzle receiving portion .

  The mist sauna device is installed in a bathroom where a laundry basket is installed and sprays hot water from the nozzle to increase the humidity and temperature of the bathroom. In the mist sauna device, a plurality of nozzles are attached to the laundry basket, Since a flow path for supplying hot water to each of the nozzles is formed inside, when taking a bath in a mist sauna, hot water is sprayed from the nozzle of a laundry basket installed in the bathroom to bring the mist into the bathroom. Increase the humidity and temperature of the bathroom. On the other hand, when not taking a mist sauna bath, the laundry basket can be used as a clothesline. In this way, since the laundry basket has both the function of drying clothes and the function of spraying hot water from the nozzle, it is necessary to newly install equipment such as nozzles on the ceiling and side walls of the bathroom separately from the laundry basket The mist sauna can be efficiently created by effectively using a narrow bathroom space.

  Since the nozzle is rotatably attached to the laundry basket, the mist sauna device can change the spraying direction of hot water and randomly hit the mist against the user's body.

  The mist sauna device is fixed to the laundry basket, and has a fixed nozzle receiving part having a fixed communication path communicating with the flow path of the laundry basket, and is rotatably attached to the fixed nozzle receiving part. It is attached at a position deviated from the center in a posture for spraying hot water, and has a rotation-side nozzle receiving portion having a rotation-side communication passage for supplying hot water supplied from the fixed-side communication passage to the nozzle. When spraying hot water, a force acts on the nozzle in a direction deviating from the center of the rotation side nozzle receiving portion. The force acts on the rotation side nozzle receiving part through the nozzle, and rotates the rotation side nozzle receiving part with respect to the fixed side nozzle receiving part. Therefore, according to the mist sauna device, the direction of the nozzle can be automatically changed by the water pressure of the hot water, and the spraying of the hot water can be performed with a simple and inexpensive structure without providing a separate driving means for rotating the nozzle. You can change the direction.

  The mist sauna device includes a main channel formed in the longitudinal direction of the laundry basket, and a branch channel branched from the main channel and connected to the nozzle. Since the channel cross-sectional area on the downstream side is smaller than the channel cross-sectional area, the water pressure supplied to the plurality of nozzles attached to the laundry basket is set to the same level, and the mist from the plurality of nozzles to the bathroom is almost uniform. Can be sprayed.

  Hereinafter, preferred embodiments of a mist sauna apparatus according to the present invention will be described in detail with reference to the drawings.

(First embodiment)
FIG. 1 is an image diagram of a bathroom 1 to which a mist sauna device 20 according to a first embodiment of the present invention is applied.
In the bathroom 1, a bathroom heater / dryer 3 is installed on the ceiling 1 a on the bathtub 2. Two washing baskets 4 and 4 are installed above the bathtub 2. Both ends of the laundry basket 4 are fixed to the side wall 1b of the bathroom 1, and the warm air sent from the bathroom heater / dryer 3 hits the laundry on the laundry basket 4 to dry the laundry. A remote controller 11 is attached to the side wall 1 b of the bathroom 1. The remote controller 11 has a function capable of selecting and executing a ventilation mode, a clothing drying mode, a heating mode, a cool air mode, a 24-hour ventilation mode, and a mist sauna mode. The present invention is characterized in that the laundry basket 4 has a function of drying clothes and a function of spraying hot water or cold water (hereinafter referred to as “hot water”) from the nozzle 22.

FIG. 2 is a diagram illustrating a schematic configuration of the mist sauna apparatus 20.
The mist sauna device 20 uses hot water sent from the heating heat source 5 to a heating device such as floor heating as a heat source. Connected to the heating heat source 5 is a hot water circuit 6 for circulating hot water heated by the heating heat source 5. The heat exchanger 8 is connected to the hot water circuit 6 and a water supply circuit 7 for supplying tap water, and performs heat exchange between the tap water flowing through the water supply circuit 7 and the hot water flowing through the hot water circuit 6 to heat the tap water. To do. The on-off valve 9 is normally closed, and when the mist sauna mode is set by the remote controller 11, the valve is opened and tap water is supplied to the heat exchanger 8. The flow rate adjustment valve 12 is disposed on the hot water circuit 6 and controls the temperature of the hot water flowing through the hot water circuit 10.

  Here, in general, in a water heater, a hot water amount (minimum operating flow rate) of about 3 L / min is required to make hot water. That is, the water heater does not operate at a hot water amount of 3 L / min or less. On the other hand, the mist sauna device can make a mist sauna environment in the bathroom even with a hot water amount smaller than the minimum operating flow rate of the water heater. Therefore, in the system using hot water from the water heater, water and gas for making hot water are used excessively, resulting in waste. On the other hand, the mist sauna apparatus 20 of this embodiment uses the warm water for heating produced with the heat source 5 for heating, and heat-exchanges with tap water with the heat exchanger 8, and is less than the minimum operating flow rate of a water heater. The tap water can be heated to save water and save energy.

  The heat exchanger 8 is connected to the laundry basket 4 via the hot water circuit 10. A plurality of nozzles 22 are evenly arranged and attached to the laundry basket 4 in the longitudinal direction. In the present embodiment, ten nozzles 22A, 22B, 22C, 22D, 22E, 22F, 22G, 22H, 22I, and 22J are attached to the laundry basket 4. The operation of the mist sauna device 20 is controlled according to the setting conditions (bathroom temperature, bathroom humidity, heat retention time, etc.) input via the remote controller 11.

FIG. 3 is a view showing a structure of a nozzle attached to the laundry basket 4.
The nozzle 22 includes a male screw portion 22b connected to the hot water circuit 10 and an ejection port 22a for ejecting hot water. The spout 22a is configured to spray hot water over a wide angle. The nozzle 22 sprays hot and cold water with fine particles. In the present embodiment, the nozzles 22A to 22J spray mist of 100 μm or less.

FIG. 4 is a diagram showing the internal flow path configuration of the laundry basket 4.
A first main channel 41 and a second main channel 42 are continuously formed in the center of the laundry basket 4 along the longitudinal direction. The first main channel 41 has a channel cross-sectional area larger than that of the second main channel 42. The laundry basket 4 is connected to the hot water circuit 10 so that hot water flows from the first main channel 41 to the second main channel 42. The first main channel 41 is connected to the nozzles 22A to 22E via branch channels 43A, 43B, 43C, 43D, and 43E. Further, the second main flow path 42 is connected to the nozzles 22F to 22J via branch flow paths 43F, 43G, 43H, 43I, and 43J, respectively.

  When such an instruction to execute the mist sauna mode is input to the remote controller 11, the mist sauna device 20 starts to operate in accordance with preset setting conditions.

  Specifically, the on-off valve 9 is opened to supply tap water to the heat exchanger 8. The on-off valve 9 controls the supply amount of tap water so that each nozzle 22A-22J sprays hot water at a rate of 0.02 l / min, for example. The heat exchanger 8 heats the tap water to the hot water supply temperature by the hot water supplied from the heating heat source 5. The hot water supply temperature is automatically calculated in consideration of disturbances such as the outside air temperature in the bathroom temperature when the mist sauna mode is executed. The user can arbitrarily set the bathroom temperature when the mist sauna mode is executed in the remote controller 11. For this reason, the user can appropriately change the temperature, for example, by setting the bathroom temperature to 28 degrees in summer, or setting the bathroom temperature to 43 degrees in winter. For example, when the bathroom temperature is set to 43 degrees, the heat exchanger 8 heats the tap water flowing through the water supply circuit 7 with the hot water flowing through the hot water circuit 6 so that the hot water supply temperature is set to 70 degrees. The heated hot water is supplied to the laundry basket 4 through the hot water circuit 10.

  The hot water flows from the first main channel 41 toward the second main channel 42. In the meantime, the hot water is divided from the first and second main flow paths 41 and 42 to the branch flow paths 43A to 43J, and sprayed from the nozzles 22A to 22J to the bathroom 1. The second main channel 42 has a smaller channel cross-sectional area than the first main channel 41. Therefore, even if hot water is sprayed from the plurality of nozzles 22A to 22J, the water pressure supplied to the downstream nozzles 22F to 22J is approximately the same as the water pressure supplied to the upstream nozzles 22A to 22E. Become. Accordingly, the mist is sprayed from the plurality of nozzles 22A to 22J almost evenly. The hot water is about 70 degrees when sprayed from the nozzles 22A to 22J, but is cooled by the air in the bathroom 1 after spraying, and the temperature drops to the set temperature. When the mist of set temperature spreads in the bathroom 1, the humidity and temperature of the bathroom 1 rise. When the humidity and room temperature of the bathroom 1 reach the set values for the mist sauna mode, mist is sprayed from the nozzles 22A to 22J so as to maintain the set values.

  The flow rate of hot water supplied to the nozzles 22A to 22J is as small as 0.02 l / min. Moreover, the nozzles 22A to 22J spray mist with fine particles of 100 μm or less. Therefore, the bather does not have a feeling that the mist directly hits the skin and can obtain a moist feeling.

  When the mist sauna mode is not set by the remote controller 11, the on-off valve 9 is closed. Therefore, hot water is not sprayed from the nozzles 22 </ b> A to 22 </ b> J of the laundry basket 4. In this case, a hanger or the like is hung on the laundry basket 4, and the laundry is dried. In particular, if the clothes drying mode is set with the remote controller 11, the clothes can be dried by applying warm air to the laundry dried on the laundry basket 4.

  As described above, the mist sauna device 20 of the first embodiment is installed in the bathroom 1 in which the laundry basket 4 is installed, and sprays hot water from the nozzle 22 to increase the humidity and temperature of the bathroom 1. The plurality of nozzles 22 are attached to the laundry basket 4, and the washing basket 4 has channels 41, 42, and 43 formed therein for supplying hot water to each nozzle 22, so that mist sauna bathing can be performed. When performing, the hot water is sprayed from the nozzle 22 of the laundry basket 4 to spread the mist over the entire bathroom 1, and the humidity and temperature of the bathroom 1 are increased. On the other hand, when bathing in the mist sauna is not performed, the laundry basket 4 can be used as a clothesline. As described above, since the laundry basket 4 has both a function as a clothesline and a function of spraying hot water from the nozzle 22, a new facility such as the nozzle 22 is newly installed on the ceiling 1 a of the bathroom 1. There is no need to install it on the side wall 1b or the like, and a mist sauna state can be made efficiently by effectively utilizing a narrow bathroom space.

  In the mist sauna device 20, the flow paths 41, 42, 43 are branched from the main flow paths 41, 42 formed in the longitudinal direction of the laundry basket 4, and connected to the nozzle 22. The main flow paths 41 and 42 have a flow path cross-sectional area of the second main flow path 42 on the downstream side of the flow path cross-sectional area of the first main flow path 41 on the upstream side. Since it is small, the water pressure supplied to the plurality of nozzles 22 </ b> A to 22 </ b> J attached to the laundry basket 4 can be made substantially the same, and the mist can be sprayed almost uniformly from the plurality of nozzles 22 </ b> A to 22 </ b> J onto the bathroom 1.

(Second Embodiment)
Subsequently, a second embodiment of the present invention will be described. FIG. 5 is a partially enlarged view of the laundry basket 4 applied to the mist sauna device according to the second embodiment of the present invention, and shows the structure of the nozzle 22. FIG. 6 is a diagram for explaining the principle of operation of the nozzle 22 rotating. FIG. 7 is an image diagram showing a state where mist is ejected from a rotating nozzle. 5 to 7, the nozzle 22 is illustrated in a simplified manner, and the subscripts A to J of the branch flow path 43 and the nozzle 22 are omitted for easy understanding of the drawings.
The mist sauna device of the second embodiment is different in that the nozzle 22 is rotatably attached to the laundry basket 4.

  As shown in FIG. 5, the nozzle 22 is attached to the laundry basket 4 via a fixed-side nozzle receiving portion 33 and a rotating-side nozzle receiving portion 34. The fixed nozzle receiving portions 33 are respectively fixed to the laundry basket 4 corresponding to the branch flow paths 43. The fixed-side nozzle receiving part 33 is formed with a fixed-side communication path 33 a that communicates with the branch flow path 43. On the other hand, the rotation side nozzle receiving part 34 is rotatably attached to the fixed side nozzle receiving part 33 via a shaft 35. The rotation-side nozzle receiving portion 34 is formed with a rotation-side communication path 34a that communicates with the fixed-side communication path 33a. A connection portion between the fixed side communication passage 33a and the rotation side communication passage 34a is sealed by a seal member (not shown) so that hot water does not leak from the flow path connection portion.

  As shown in FIGS. 5 and 6, the nozzle 22 is attached to the lower surface of the rotation-side nozzle receiving portion 34 at a position shifted from the center to the outside. Moreover, the nozzle 22 is attached to the rotation side nozzle receiving part 34 in a posture in which hot water is sprayed obliquely downward. As shown in FIG. 5, the fixed-side communication path 33 a and the rotation-side communication path 34 a are formed so as to supply hot water supplied directly from the branch flow path 43 obliquely toward the nozzle 22.

  In such a laundry basket 4, hot water supplied to the branch flow path 43 is supplied to the nozzle 22 via the fixed side communication path 33 a and the rotation side communication path 34 a and sprayed from the nozzle 22. At this time, as shown by an arrow F1 in FIG. 6, the nozzle 22 is supplied with hot water obliquely downward via the fixed side communication path 33a and the rotation side communication path 34a, and ejects mist. At this time, as shown in FIG. 6, a force F <b> 2 opposite to the direction in which hot water is sprayed (the direction in which mist is ejected) acts on the nozzle 22. The nozzle 22 is attached to the rotation side nozzle receiving portion 34 in a posture in which hot water is jetted obliquely downward. As shown in FIG. 6, when the force F2 is disassembled in the xyz-axis direction, the force F3 in the x-axis direction is fixed to the shaft 35 that pivotally supports the rotation-side nozzle receiving portion 34 with respect to the fixed-side nozzle receiving portion 33. It does n’t move. The force F4 in the y-axis direction is fixed to the laundry basket 4 and does not move. On the other hand, only the force F5 in the z-axis direction is not fixed. Therefore, the rotation side nozzle receiving portion 34 rotates in the K direction in the drawing according to the force F5. That is, the nozzle 22 is automatically rotated by the hot water pressure supplied from the branch flow path 43 and changes the direction in which the mist is ejected.

Therefore, according to the mist sauna apparatus of 2nd Embodiment, since the nozzle 22 is rotatably attached to the laundry basket 4, it can change the spray direction of hot water, and can randomize how the mist hits a user's body. .
In particular, as shown in FIG. 7, the plurality of nozzles 22 attached to the laundry basket 4 change the mist ejection direction apart by the hot water pressure supplied from the branch flow path 43. The hitting method becomes even more random and can give comfort to the user.

  The mist sauna device according to the second embodiment is fixed to the laundry basket 4 and is rotatable to the fixed-side nozzle receiving portion 33 having a fixed-side communication passage 33 a communicating with the branch flow path 43 and the fixed-side nozzle receiving portion 33. The nozzle 22 is attached at a position offset from the center in a posture to spray hot water obliquely downward, and has a rotation side communication passage 34a for supplying hot water supplied from the fixed side communication passage 33a to the nozzle 22. Therefore, when spraying hot water from the nozzle 22, a force acts on the nozzle 22 in a direction shifted from the center of the rotation-side nozzle receiver 34. The force acts on the rotation side nozzle receiving part 34 via the nozzle 22 and rotates the rotation side nozzle receiving part 34 relative to the fixed side nozzle receiving part 33. Therefore, according to the mist sauna device of the second embodiment, the direction of the nozzle 22 can be automatically changed by the hot water pressure, and it is simple and inexpensive without providing a separate driving means for rotating the nozzle 22. The structure can change the spray direction of hot water.

In addition, this invention is not limited to the said embodiment, Various application is possible.
For example, instead of the laundry basket 4, a laundry basket 50 shown in FIG. In the laundry basket 50, main flow paths 51, 53, and 52 are continuously formed in the longitudinal direction. The main channels 51 and 52 opened from both ends of the laundry basket 50 have a channel cross-sectional area larger than that of the main channel 53 therebetween. The laundry basket 50 is supplied with hot water from both directions of the main flow paths 51 and 52. Since hot water is sprayed from the nozzles 22A to 22C and 22H to 22J, the water pressure decreases toward the center. However, since the cross-sectional area of the main flow path 53 connecting the main flow paths 51 and 52 is smaller than the main flow paths 51 and 52, the water pressure of the hot water flowing through the main flow path 53 is approximately the same as that of the main flow paths 51 and 52. Thus, hot water is sprayed from the nozzles 22A to 22J almost uniformly.
The main channel of the laundry basket 4 may be provided in a substantially conical shape in which the channel cross-sectional area continuously decreases from the upstream side toward the downstream side.
Moreover, in the said embodiment, bathroom heating drying and mist sauna control were performed by one remote control 11, However, You may provide the remote control for bathroom heating drying and the remote control for mist sauna separately.
Moreover, in the said embodiment, the bathroom temperature set with the remote control 11 was set. On the other hand, the bathroom temperature may be automatically set according to the temperature of the hot water supplied to the nozzle 22 (hot water supply temperature). Specifically, for example, the user can appropriately change the hot water supply temperature to cold water, 40 degrees, 50 degrees, 60 degrees, and 70 degrees with the remote controller 11. When the hot water supply temperature is set to 70 degrees, the heat exchanger 8 adjusts the amount of hot water flowing through the hot water circuit 6 so that the temperature of the hot water flowing through the hot water circuit 10 becomes 70 degrees, and the water flowing through the water supply circuit 7 Heat the water. The heated tap water is supplied to the laundry basket 4 through the hot water circuit 10. When the hot water supply temperature is set to cold water by the remote controller 11, the flow rate adjustment valve 12 is closed to stop the hot water flowing through the hot water circuit 6, and the tap water flowing through the water supply circuit 10 is directly passed through the hot water circuit 10 as a washing basket. 4 is supplied. In these cases, hot water is sprayed from the nozzle 22 at the hot water supply temperature set by the remote controller 11, and mist of the hot water supply temperature spreads in the bathroom 11, thereby increasing the humidity and temperature of the bathroom 1.
Moreover, in the said embodiment, although the hot water amount supplied to the laundry basket 4 was 0.02 L / min, the hot water amount supplied to the laundry basket 4 is not limited to this, It can set suitably. .
