- At least the tank 30, the discharge hose 41, and the circulation pump 40 are housed in the same waterproof cover 20.
- water before or after heating is supplied to the tank 30 from a water supply source using a tap water at a position above the water level LV when the tank 30 (heat exchange tank 32) is full.
- a water injection nozzle 35 connected to a hose 62 The nozzle 35 is arranged so that the position of the opening end for water injection is set at a predetermined height (for example, 25 mm) from the water surface LV (see FIGS. 6 and 7).
- the steam generator for a sauna is attached to the rim surface RM with the suction port 71 and the outlet 72 protruding above the rim surface RM and facing the inside of the bathtub.
- a steam generator for a sauna that can be attached to the rim surface of a bath tub for ordinary households is configured.
- the arrangement of the tanks described above is not limited to that shown in FIG. 10, and for example, as shown in FIG. 11, the storage tank 31 and the heat exchange tank 32 are mutually connected.
- Each of the tanks may be separately formed so as to have another internal space, and a communication path CM for communicating the internal spaces of the two tanks may be provided. Through this communication channel CM, hot water from the water heater injected into the heat exchange tank 32 and water droplets from the heat exchange tank 32 when gas-liquid separation is collected are sent to the storage tank 31 and collected. can do.
- the outline of the operation of the steam generator 11 according to the present embodiment will be described with reference to FIG. This operation is performed around the microcomputer 90. It is assumed that the temperature of the water (hot water) supplied from the water heater at the time of pouring water into the steam generator 11 is 37 to 50 ° C.
- the processing executed by the microcomputer 90 includes “standby / preparation separation processing” (whether the steam generator 11 should be maintained or switched to the standby state, or a preparation operation for mist operation).
- “Preparation operation” processing to ensure that the storage tank 31 has a temperature suitable for the sauna bath and an amount of hot water suitable for the mist operation
- “Must operation” The process of generating steam (mist) from the outlet 72 of the steam generator 11 using hot water prepared by the preparatory operation and responding to the user's remote control operation.
- Steam temperature setting process (steam temperature setting process generated during mist operation).
- Fig. 12 shows an example of the process from standby standby, through preparatory operation, and back to standby again.
- the preparation operation described above is executed, and the amount of hot water and the temperature required for starting the mist operation are supplied. Secured (time t 2).
- the tank 30 storage tank 31 and heat exchange tank 32
- the parts connected to it are subjected to high-temperature sterilization.
- the mist operation starts and the sauna bath is enabled (see Fig. 2).
- the sauna bath continues for a predetermined period of time (for example, 15 minutes) (time t4)
- the steam generator 11 enters a standby state for a certain period (for example, 1 minute).
- this waiting time time t4 to t5
- the mist switch B ⁇ Ijt4,
- the second sauna bath that is, when the user presses the mist switch (time t 6) before the predetermined time (for example, 15 minutes) has arrived, the waiting time (time t 6 ⁇ T 7).
- the steam generator 11 drains (time t6' to t8), and the standby state is established.
- the sauna since the sauna space is not formed by using the entire bathroom as in the prior art, the sauna is not used to form the sauna space. The occurrence of such a phenomenon can be almost eliminated.
- this bathtub sauna system sprays steam into the bathtub and covers the bathtub with a cover such as a bath lid, so that the stuffiness inherent in the sauna room can be significantly reduced.
- the space where the steam needs to create a sauna environment is only required inside the bathtub, so that comfortable temperature and humidity can be obtained in a short time. In other words, the convenience that the waiting time is shorter than that of the bathroom system using a bathroom can be obtained. In addition, the shorter waiting time reduces the use of electric energy and water resources, and can provide a sauna system that meets cost and resource saving requirements.
- steam is generated toward the bathtub used for normal bathing (whole body bath, half body bath, etc.), and the steam retained in this bathtub can be used for sauna bathing, making it easy to use for households.
- such a steam generator 11 can be attached to a portion of the bathtub for general households at a location “F” on the rim surface which is easy to secure in a small space, and the steam can be generated and injected toward the bathtub. it can.
- the steam generator 1 1 itself must be installed along the rim surface
- a narrow rectangular tank 30 having a narrow width and having a short direction perpendicular to the longitudinal direction is provided, and necessary components are arranged along the longitudinal direction of the tank 30. are doing.
- the storage tank 31 is formed below the tank 30 and the heat exchange tank 32 is formed above it, the storage of hot water, the circulation and injection of hot water, the suction of external air, Operations such as gas-liquid separation and steam generation, steam blowing, collection of water droplets generated at the time of gas-liquid separation, and catching of hot water from a water heater have been implemented with almost no useless space centered on this tank 30. It can be performed in a high-density, compact device.
- the width (ie, shape) of the tank 30 (actually the waterproof cover 20) in the short direction can be kept to a minimum, so that the space above and below the rim surface of the bathtub can be used. And can be installed relatively easily. Therefore, it is possible to provide a steam generator for a bathtub / sauna that can be easily used in ordinary households, and it is relatively easy to secure an installation place and there is almost no sacrifice in the space of a washing place.
- a supply channel (water injection nozzle 35, water supply hose 6) that supplies water before or after heating from a water supply source using water as a water source to tank 30 (or storage tank 31).
- a heat insulating material may be attached to the outer surface of the tank 30 or the primary waterproof compartment (the area between the tank 30 and the waterproof cover — 20) It is effective to design the air volume of the space to a minimum.
- the steam generator according to the present invention has a small size, has a shape that can be easily installed in a narrow space, and can be easily attached to a bathtub used in a general household or the like. Therefore, if this steam generator is used, the bathtub can be easily and effectively used as a bath.
