Description

1252102 (1) EMBODIMENT OF THE INVENTION [Technical Field] The present invention relates to a three-warm steam generating device which is provided in a bath of a general household and which generates a steam for a warm bath, and in particular, relates to mounting The design of the constituent elements of the three-warm steam generating device in the rib surface of the bath having a small amount of space. [Prior Art] In recent years, from the viewpoint of beauty or health maintenance, the effect of the three warm baths has been proposed, and a method or a machine that can perform a warm bath even in a general household is proposed. The simplest three-warm bath in a typical home is to drain hot water from the bath to its half full bath (hip bath), cover the bath cover to the bather's shoulder and bathe. Thereby, a sauna can be enjoyed by generating steam in the bath. However, in the case of the three-warm bath method, it is a simple method, the temperature of the vapor is insufficient, and there is no sufficient effect. Therefore, the bathroom is used to form a warm space. The known proposal is to warm the bath. For example, Japanese Laid-Open Patent Publication No. Hei 5-3 3 7 1 (Document 1) has a steam ejecting portion for ejecting steam generated in a steam generating portion into a bathroom interior. The steam from the steam generating portion is supplied to the inside of the steam ejecting portion and diffused, and then discharged into the bathroom from the discharge port of the steam ejecting portion. In addition, in the Japanese Patent Publication No. 2 000- 5 5 3 9 7 (Document 2), the proposal (2) 1252102 is used to use the bathroom as a warm space. According to this, in the bathroom, for example, a warming device main body is provided beside the bathtub. The main body of the three-warming device is formed by mixing the negative pressure generated by the warm water spray and the air sucked into the bathroom behind the nozzle to mix the air with the warm water sprayed from the nozzle. The heated air is discharged into the bathroom through the duct, and the warm water droplets adhering to the duct are recovered and accumulated in the warm water collecting tank. The water to be heated is reheated, and is sprayed from the nozzle to form a mulling device. Further, in Japanese Patent No. 3406967 (Document 3), there is another use for the use of the bathroom as a warm space. The steam generating device proposed in the document 3 is provided with a steam supply means such as a water supply means for supplying a circulating means I or a warm water supply (replenishment) to the circulation means by the steam generation section '. The generated air supply means of the steam supply. A supply means such as water, as seen in the literature 3, has a supply source such as water and a pipe interposed between the electromagnetic valves. A supply source such as water is a hot water supply that supplies the water itself or a warm water of a predetermined temperature using tap water U to construct the tap water as water source or warm water, and constitutes a part of the supply (supply) into a circulation means. Drain pan. As shown in the above-mentioned documents 1 to 3, even in a general household, a sauna space is formed by a bathroom, and a sauna is implemented. However, the conventional three-warm steam generating device described in the above documents 1 to 3 is a three-temperature nozzle fan that forms a warm space by using the entire bathroom. And the recycling of the ring, the construction of the hand, will, and, and, and become. To the structure of the energy and the -6- (3) 1252102 to be accused of various problems.

The first problem is that the wall surface of the bathroom is dew condensation, which may cause so-called mold and the like. The second problem is that the whole bathroom interior is caused by high temperature and humidity. The bather of the three warm baths is very unsatisfied because of the difficulty in breathing. Further, the third problem is that the supply of steam to the entire bathroom is long, and the waiting time for the temperature and humidity suitable for the warmth is long. Along with this, the fourth problem is that the waiting period is long, and it is pointed out that there is a large amount of use of electric energy or water resources. These problems are apparent from the fact that the bathroom as a whole is a warm space. For this reason, such as the above-mentioned hip bath, if the three warm spaces can be left in the bath, such problems can be suppressed or solved.

However, in the case of using a conventional warming device or a steam generating device to generate a warm space in a bath of a general household, it is usually necessary to arrange such a device in a bathroom where it is difficult to secure such a large space because of the device The size is too large, and the shape of the device is different, so it is very difficult to ensure the location. If it can be set, part of it will cause inconvenience such as a narrowing of the bath. SUMMARY OF THE INVENTION The present invention has been developed in view of such a conventional problem, and is provided in a small size and having a shape that can be easily installed in a narrow space, and can be easily attached to a bath used in a general household or the like, and can be easily A steam generating device using a bath as a warm space is used as its purpose.

For this reason, the user, after completing the operation preparation of the steam generating device 1 1 , enters the inside of the bath 1 而 as shown in Fig. 2, and takes the bath cover FT and retains a part thereof. The posture of the face is extended, and the operation of the steam generating device 1 1 is commanded from the remote controller 14. Thereby, the hot water storage portion of the bath 10 is used as a warm space, and the three warm baths can be enjoyed while sitting in the bath ( Sweat bath) -9 - (6) 1252102 The following description will be given in detail of the configuration and operation of the steam generating device 1 1 . The steam generating device 11 is as shown in Figs. 3 to 5 . A box having a substantially rectangular parallelepiped shape is shown in Fig. 3. Fig. 3 is a view showing a user (bath side) of the sauna (hereinafter referred to as a front view). Fig. 4 is a left side view, Fig. 5 Is to display the right side of the map.

The steam generating device 具备 includes a waterproof cover 20 as a component constituting a casing of the casing, a ventilation duct 2 1 provided on the upper side of the waterproof cover 20, and a ventilation duct covering the ventilation duct 2 1 top cover 22. The inside of the waterproof cover 20 is provided with a water tank 30 which is divided by the upper and lower side transmission sections 30a and integrally formed into a space which is integrally formed. In the water tank 3, the water tank portion 3 1 on the lower side of the section portion 30a is used to store the warm water storage tank 3, and the upper water tank portion constitutes the heat exchange water tank 3 2 for heat exchange. An in-tank filter 34 is provided in the segment portion 30a.

In addition, the storage tank 3 1 and the heat exchange water tank 3 2 are not necessarily limited to those integrally molded as described above, and may be formed into a storage space which is integrally formed by being molded by another individual and integrated, and may be separately formed. After being formed by another individual, the arrangement of the other individual is maintained, and the water tank space of both is connected through the communication portion. A tapered surface is mounted on the left side wall of the third embodiment of the heat exchange water tank 3 2, and the right side wall is formed upright with respect to the right side wall. In the tapered surface, as will be described later, one of the water supply nozzles 35 for adding water to the water tank is provided, and the inner side surface of the vertical wall is provided with a pump to circulate as follows (7) (7) 1252102 The hot water is sprayed toward the spray nozzle 36 in the water tank. The storage tank 3 1 is formed in a substantially square shape, and one of the side walls (the left side wall of Fig. 3) is provided with an electric heater (sheared heaters) 37 for heating the water in the water tank. The electric heater 37 penetrates the side wall in an airtight state and is disposed at a position where the heating portion is inside the water tank and the terminal portion is located outside the water tank. The electrode portion positioned at the outer side of the water tank is formed to be airtight by the electric heater cover 38. Thereby, the electrode portion of the electric heater 37 can be covered with airtightness by a double waterproof partition. That is, the waterproof cover 20 and the accumulating water tank 31 form a waterproof partition, and the inside of the electric heater cover 38 constitutes a secondary waterproof partition. The electric heater 37 is more reliably protected by the double waterproof partition. Further, in order to ensure the waterproof performance of the waterproof partition, it is important that the rising internal pressure reliably escapes to the outside by warm water. For this reason, in the present embodiment, in order to reliably escape the internal pressure which rises in the secondary waterproof zone to the primary waterproof partition, a vent filter of the microporous membrane is provided. Further, in order to escape the internal pressure of the primary waterproof partition to the outside, a separate cable is used for the power cable 63 to be described later. Borrow this. The hollow portion of the tube can be used and the internal pressure can escape to the outside through the power box 13. The water in the water tank 3 1 is directly and heated by being energized by the electric heater 3 7 . A circulation 埠3 1 a is formed in the other side wall (the right side wall of Fig. 3) of the storage tank 3 1, and a pump filter 39 is attached to the inlet of the circulation 埠3. On the outer side of the side wall on which the circulation 埠3 1 a is formed, a circulation pump 40 is provided as shown in Fig. 3 of -11 - (8) (8) 1252102. The suction port of the circulation pump 40 is airtightly connected to the circulation port 31a, and the discharge soft water pipe 41 is connected to one end of the discharge port. The other end of the discharge soft water pipe 4 1 rises upward (see FIG. 5) and reaches a predetermined position of the side wall of the heat exchange water tank 32, and is airtightly inserted into the side wall at the position and is connected to the injection nozzle 36. Combine. For this reason, once the circulation pump 40 is driven, the warm water accumulated in the water tank 3 1 passes through the circulation 玮 3 1 a, the circulation pump 40, and the discharge soft water pipe 4 1 to reach the injection nozzle 36, and is directed from the injection nozzle 36. The heat exchange sink 3 2 is sprayed. Further, a discharge port 3 1 b is formed at the bottom of the storage tank 3 1 . The discharge port 3 1 b is connected to the suction port of the drain valve 50 (three-way valve) on the lower side of the storage tank 3 1 . In the drain valve 50, in addition to the suction port, two drain ports are provided, and since one of them constitutes a normal drain passage, it passes through the check valve 51 to reach the normal drain port 52. The normal drain port 5 2 (see Fig. 5) is connected to the drain pipe. Since the other drain raft constitutes an emergency drain passage for emergency use, it still passes through the emergency drain port 5 3 (refer to Fig. 5), and for example, faces the drainage space under the bath and is often open. For this reason, by controlling the electromagnetic portion of the drain valve 50 by the control signal, it is possible to switch to three states of the closed (drain 〇FF), the open 1 (normally drained), and the open 2 (emergency drain). Further, the bottom surface 'of the waterproof cover 20 is formed in a stepped shape at a substantially central position thereof through the step portion 20a as shown in Figs. 3 to 5, and a normal drain port 5 2 is attached to the step portion 20 a in the lateral direction. And emergency drain 5 3 . By this lateral mounting, it is easy to install work or maintenance management. On the other hand, on the lower side of the storage tank 3 1 , a water adding mechanism is provided in addition to the above-described drainage machine -12-(9) (9) 1252102. Specifically, in the step portion 20a, as shown in Fig. 5, a water supply port 504 is provided, and the water supply port 504 is configured to supply warm water from a hot water supply device (not shown). The water supply port 504, as shown in Fig. 8, is prevented from flowing back from the water supply nozzle 35 to the check valve of the hot water supply device through the water or warm water (i.e., sewage) in the water tank 30. Water supply machine combined. The check valve 500 is provided with an air gap for preventing backflow between the water supply opening end provided at the tip end of the water supply nozzle 35 and the water surface reference surface in the water tank 30 (described later) ) Complementary, it would be great if the prevention of such a water countercurrent is more certain. Further, the above-described check valve 500 may be formed to be provided on the inner side of the waterproof cover 20. Further, as shown in Fig. 8, the water supply port 54 is passed through the manual valve 55, the pressure escape valve 56, the hot water supply filter 57, and the flow sensor 1 1 6 inside the waterproof cover 20. The hot water supply thermistor 1 17 , the electromagnetic water supply valve 60 , and the dosing valve 6 1 are connected to the water supply soft water pipe 6 2 . As shown in Fig. 4, the water supply hose 6 is erected upward and is airtightly connected to the water supply nozzle 35 having the side wall (conical wall) 3 2 a of the tapered surface of the heat exchange water tank 32. The water supply nozzle 35, the water supply soft water pipe 62, and the water supply port 504 are supplied with water from the water supply source using tap water as a water source to the water tank 30 (heat exchange water tank 3 2 ). A portion of the supply channel of the present invention. The water adding nozzle 35, as shown in Fig. 6, has a tapered wall 3 2 a in the heat exchange water tank 3 2 from the inner side toward the outer side and one end thereof penetrates and the phase - 13 - (10) (10) 1252102 The L-shaped tube 351 which is hermetically arranged by the sealing member and hermetically arranged, and the δ of the L-shaped tube 351 which penetrates the tapered surface wall 32a is hermetically sealed by using a sealing member such as an O-ring. a connecting pipe 3 5 2 that is coupled to the other side and has an end portion facing downward and a nozzle body 3 5 3 that is coupled to the other end of the L-shaped pipe 35 1 inside the heat exchange water tank 32 . The water supply flexible water pipe 62 is connected to the connection pipe 325. Further, on the outer wall surface of the tapered wall 3 2 a, a holding plate 354 that holds the L-shaped pipe 35 1 and the connecting pipe 35 2 is attached. The other end portion of the nozzle body 3 5 3 is bent into a substantially L shape. The nozzle body 3 53 is disposed upward along the tapered surface of the heat exchange water tank 3 2 and is bent such that the open end of the substantially L-shaped front end portion is positioned to be filled with water of the heat exchange water tank 3 2 The water surface reference surface LV is only a predetermined height α. For this reason, in the usual watering, as shown by the arrow Α in Fig. 6, the water supply hose 62, the connecting pipe 3 5 2, the L-shaped pipe 35 1 , and the nozzle body 3 5 3 are heated. The water tank 3 2 is exchanged, that is, warm water from the hot water supply machine is supplied to the storage tank 31. That is, the warm water from the hot water supply device that adds water to the heat exchange water tank 3 2 is stored in the storage tank 3 1 ,, and the electromagnetic valve is opened and closed by the control signal while the manual valve 55 is opened. In the case of 60, it is possible to intermittently control the supply of the hot-exchange water tank 3 2 of the water-injecting nozzle 35 which is supplied to the hot water supply device from the outside. The predetermined height of the opening end of the discharge body of the nozzle body 3 53 is, for example, the heat exchange water tank 3 2 is filled with water (the water surface is the position of the LV), and -14-(11) (11) 1252102 is in the above-mentioned check. When the valve 500 is faulty and causes tap water to break or malfunction, it is set to prevent the so-called water or warm water (when the sewage is treated) from sucking in and countercurrent to the nozzle body 3 5 3 to a height of 25 mm or 2 5 mm or more. Further, the arrangement of the water supply nozzles 35 is not limited to the structure shown in Fig. 6 in detail, and may be, for example, as shown in Fig. 7. According to the structure shown in Fig. 7, a recess 32b that sinks inward is formed in a part of the tapered wall 3 2 a of the heat exchange water tank 3 2, and the water supply nozzle 35 is attached by the recess 3 2 b. In other words, the water supply nozzle 35 has a nozzle body 3 which is provided at a position corresponding to the recessed portion 3 2 b as shown in Fig. 7, in which the shoulder portion of the heat exchange water tank 32 faces the inside of the water tank and is airtightly protruded. 6 1 and a connecting pipe 3 6 2 that is disposed through the shoulder and is airtight. In the connection pipe 362, a water supply flexible water pipe 62 extending from below is connected to the outside of the heat exchange water tank 32. The other end portion of the nozzle body 361 is bent in an inverted v shape as shown in the figure, and the open end of the tip end thereof is inclined toward the inside of the pool 3 2 . From the open end at this time, to the distance of the water surface LV when the heat exchange water tank 3 2 is full of water, in the same manner as described above, since the backflow of the sewage in the water tank 3 0 ( 3 2 ) is prevented, it is set at the predetermined 値a ( 2 5 mm or more). In such a portion of the tapered wall 3 2 a, by forming the recessed portion 32b that is sunk inside, there is no need to form the water-filling nozzle 35 to form a hole for the tapered wall 3 2 a of the water tank 3 2 . In the portion of the recessed portion 3 2b, the space in which the water adding nozzle 35 is mounted can be secured. For this reason, the watering nozzle 35 can be moved back to the conical wall 3 2 a and simply installed. The water-filling nozzle 35 also has the advantage of being so constructed. -15- (12) (12) 1252102 Further, at a predetermined position at the bottom of the waterproof cover 20, a cable 6 3 for electric heater power supply connected to the power supply box 13 and various cables for electronic circuit power supply are connected. 64. The communication cable 65 is airtightly connected. Although these cables are not shown, they form a necessary position around the inside of the cover. On the other hand, the ventilation duct 21 is attached to the ceiling body 70 that covers the upper portion of the waterproof cover 20. The ventilation ducts 21 are separated from each other by a predetermined distance to form a suction port 7 1 and an air outlet port 7 as shown in Fig. 3. The suction port 71 and the air outlet 72 communicate with the internal space of the heat exchange water tank 32. For this reason, the air of the bathroom (actually, because of the use of the shower cover, the inside of the bath) can be sucked into the heat exchange water tank 32 through the suction port 71, and the other side can be heated through the air outlet 7 2 The air inside the exchange tank 3 2 is discharged. The opening and closing cover 2 2 a is attached to the front side of the top cover 22, and when the three-temperature warm bath is not performed, the cover 2 2 a (the state of Fig. 3) is closed to constitute the closed suction port 7 1 and the air outlet 7 2 . For this reason, the hot water or dust of the bathtub B T is prevented from entering the steam generating device 1 1 through the suction port 71 and the blow port 72. When the sauna is implemented, as shown in Fig. 5, the cover 22a is opened, and a mechanism capable of maintaining the open state is provided. Further, in the ceiling body 70 of the heat exchange water tank 32, as shown in Fig. 3, the separator 73, which is installed as a barrier member for gas-liquid separation, is suspended toward the inside of the hot water tank 32. The separator 173 is positioned at an intermediate position between the suction port 7 1 and the air outlet 7 2 , and a tapered surface constituting an obtuse angle is attached to the ejection body that comes from the suction port 7 1 and the ejection nozzle 36. Further, the position of the lower end of the separator 733 is located at a position lower than the outlet port 7 2, whereby -16-(13) 1252102 is formed from the suction port 7 and the injection nozzle 36. Directly reach the blowout port 7 2 . For this reason, the air/liquid mixture at a high temperature in the separator 173 is gas-liquid separated by the collision, and only the saturated water vapor is discharged from the heat exchange water tank 32 through the air outlet port 72.

When this is described in detail, the warm water circulated to the injection nozzle 36 by the pump 40 is ejected at a high speed from the injection holes formed in the plurality of injection nozzles 36 toward the inside of the heat exchange tank 3 2 . The air that has been drawn into the bath through the suction port 7 can be drawn by the friction accompanying the ejection. This attraction can be configured for the following reasons. By the warm water flow injected into the heat exchange water tank 3 2, the air in the water tank is given kinetic energy, and the air is moved in the water tank because a negative pressure is generated in the vicinity of the suction port 7 1 Negative pressure can draw air from the suction port 7 1 . Moreover, the warm water is because the high-speed jet is simultaneously sprayed from the plurality of injection holes.

Since the contact area with the air inside the heat exchange water tank 3 2 is increased, more air is sucked into the water tank through the suction port 71. The sucked air is heated and humidified because it is in parallel with the high-temperature water (warmed water sprayed) in the heat exchange water tank 32. A portion of the heated/humidified air-water mixture 9 collides with the inclined surface of the separator 73, and the remaining portion collides with the wall surface of the heat exchange water tank 32. By this conflict, the gas-liquid separation 'is separated into saturated water vapor and water. The water falls directly or to the wall surface and falls to the accumulation tank 3 1, and is recovered. On the other hand, the saturated water vapor is discharged through the air outlet port 7 toward the bath and -17-(14) 1252102. Further, as can be understood from Fig. 3, on the outside of the heat exchange water tank 3 2, the control substrate 80 is provided in a state where the soft water pipe 4 1 is discharged and the temperature is in contact with the temperature. The control board is equipped with a control electric shoe electronic component that is responsible for the control center of the steam generating device 11.

The detection circuits 96 and 97 drive circuits 98~ 100. The various circuits are electrically connected to various detection means and driving means of the vapor generation cost, and the signals detected by the receiving/detecting means are sent to the microcomputer 90, and are outputted by the processing of the microcomputer 90. Control signal receiving, transforming and driving means. Once specifically described, in the suction ports 7 1 and 72, the heat 1 1 0, 1 1 1 as the detecting means for detecting the temperature is respectively provided, and the thermistor 1 1 0, 1 1 1 The detection signals are distributed to the A/D converters 92, 95. The right wall of the water does not have 80, and the actual I 81 micro-processing production assembly can be functional first to collect the circuit and . In the case of the heat exchange sink 3 2 at the predetermined position of the edge (upper limit) of the heat exchange sink 3 2 There is an overflow (〇F) reference surface sensor 1 1 2, and the reference surface sensor and the detection signal of the detector 1 12 are sent to the detection circuit 96. Moreover, the upper limit of the side wall of the storage tank 3 i is located at a slightly lower position, and the lower limit reference surface sensor 1 1 3 is provided at a position lower than the cycle 3 1 agf, and the reference surface sensor is provided. The detection means of 1 1 3 is sent to the detection circuit 97. A common reference surface sensor 1 1 4 for providing a comparison reference signal is mounted at a predetermined position near the bottom of the storage tank 3 1 , and the detection signal of the common reference surface sensor 丨丨 4 is sent as a reference signal. To the detection circuit 9 6 , 9 7 . These reference surface sensors 1 1 2 to 1 1 4, especially because of the detection accuracy required, use an electrode switch of the same path (Ο N ) when water reaches the position of the sensor. Further, in the storage tank 3 1 , the lower limit reference surface sensor 1 1 3 is lower than the above-described lower limit reference surface sensor 1 1 , and a warm water thermistor 1 1 is attached to a position close to the center portion of the water tank 3 1 . 5. The detection signal of the warm water thermistor 1 i 5 is sent to the A/D converter 93. The detection signal of the hot water supply thermistor 1 17 inserted into the water supply water supply line is sent to the A/D converter 94, and the detection signal of the flow sensor 1 16 is directly sent to the microcomputer 90.

Further, the arrangement structure of the water tank is not limited to the above, and as shown in Fig. 11, for example, the outer heat exchange water tanks 3 2 may be formed so as to be formed separately from each other, and the two are provided. The internal space of the sink is connected; CM. Through the communication passage CM, warm water from the water supply to the heat exchange water/hot water supply device or water droplets when the liquid in the heat exchange water tank 32 is separated can be fed and recovered to the accumulation water tank 31. The outline of the steam generating operation of the present embodiment will be described with reference to Fig. 2 . This operation is performed by the microcomputer 90, and when the steam generating device 1 1 is filled with water, when the water is supplied from the hot water, the I pump 40 is filled with water, and the water is supplied by the soft water pipe (for example, 1 and blown out). In the direction of the rib surface of the 1 0 figure [the groove 3 1 and the internal air passage channel 3 2 of the recovered gas is set to U. And the machine is supplied -23- (20) (20) 1252102 The temperature of the water (warm water) is set to 3 7 to 50 ° C. The processing performed by the microcomputer 90 is "interval processing of the standby and preparation" (the steam generating device should be performed) The process of maintaining the standby state or the switching process, or the preparatory operation of the preparatory operation for starting the fog operation, includes the "preparation operation" (the temperature suitable for the sauna and the amount suitable for the fog operation) The warm water is ensured in the process of storing the water tank 3 1 and the "fog operation" (using the warm water prepared by the preparation operation, and the steam is blown from the air outlet 72 of the steam generating device 1 1 in response to the remote controller operation of the user. (mist) treatment, and "blowing of steam" Various processes of the temperature setting process (the process of setting the temperature of the vapor generated during the mist operation). In Fig. 2, the process of preparing from the standby state and returning to the standby state is exemplified. In the standby state, when the user presses the preparation switch of the remote controller 14 (time 11), the preparatory operation is carried out, and warm water (time t2) of the necessary amount and temperature is ensured at the start of the mist operation. During operation, the water tank 30 (the storage tank 3 1 and the heat exchange water tank 3 2 ) and the portion communicating therewith are additionally subjected to high-temperature sterilization. After the preparation, when the user presses the mist switch of the remote controller 14 (time t3), the user enters When the mist is operated, it can be a sauna (refer to Figure 2). When the sauna is kept for a predetermined period of time (for example, 15 minutes) (time 14), the steam generator 1 1 enters the period of time (for example, 1 minute) standby state. During this standby (time t4~t5), the user can continue the sauna again, when pressing such a mist switch (time-24-(21) (21) 1252102) From this The point is again in the fog operation. On the way of the second warm bath, that is, before the user reaches the predetermined time (for example, 5 minutes), when the user presses the mist switch (time 16), the standby time is again entered ( Time t6 to 17) In this standby, the user can stop the warm-up bath. When the preparation switch is pressed (time 16 / ), the steam generator 1 1 performs drainage (time t6 > t8) and returns to the standby state. In this way, the user can perform the mist operation and enjoy the sauna. For this reason, according to the bath three-warm system of the present embodiment, since the warm space is not formed by using the entire bathroom as in the prior art, the cause can be almost eliminated. The moldy surface of the bathroom of the three-bath bath produces mildew and the like. Further, in the three-warm system for the bath, the steam is sprayed toward the inside of the bath, and the cover such as the shower cover is used for covering the bath, so that the breathing difficulty unique to the sauna is greatly reduced. Moreover, the space in which the steam can be made into a warm environment is completed in the interior of the bath, so that a comfortable temperature and humidity can be obtained in a short period of time. That is, compared with the sauna system using the bathroom, the convenience of the so-called waiting time is obtained. Moreover, the short-term waiting period, the use of electric energy or water resources is reduced, and it can provide a three-warm system that meets the requirements of provincial cost and resource saving. In particular, since it is suitable as a bath for use in a normal bath (body bath, half body bath, etc.) and generates steam, it can be used as a warm bath by the vapor retained in the bath, so that it can be used simply and can be provided. As a system suitable for general households. In this case, in a bath suitable for general household use, if there is a small space between -25 - (22) (22) and 1252102, such a vapor generating device 11 is installed at a portion below the easily secured rib surface, and The steam can be generated and sprayed toward the bathtub. The steam generating device 1 1 is in a mounted state, and has a substantially square-shaped water tank 3 having a narrow width and a short axis direction orthogonal to the direction along the rib surface. 0, the necessary constituent elements are arranged along the long axis direction of the water tank 30. In addition, since the water storage tank 3 is formed in the lower portion of the water tank 30, the heat exchange water tank 3 2 is formed in the upper portion thereof, so that the warm water can be accumulated and heated, the warm water can be circulated and sprayed, the outside air can be sucked, and the gas and liquid can be absorbed. The operation of separation, vapor generation, vapor blowing, recovery of water droplets generated during gas-liquid separation, and hydration of warm water from a hot water supply device are performed with the water tank 30 as a center, and wasteful space is almost eliminated. It is a device with a high density and is miniaturized. In particular, since the width (i.e., the shape) of the short-axis direction of the water tank 30 (actually the waterproof cover 20) can be suppressed to the minimum necessary, the rib surface of the bath can be compared with the space above and below. Easy to set up. For this reason, it is possible to provide a steam generating device for bathing and warming which can be easily used in a general household, in a state where it is relatively easy to ensure that the installation site is relatively easy. In addition, a supply passage (including a water supply nozzle 35, a water supply hose 62, and a water supply nozzle) for supplying water before or after heating from the water supply source using tap water as a water source to the water tank 30 (or the water tank 3 1) is provided. The flow path of the water supply port 54 is disposed at a position higher than the water surface LV of the water tank 30 when the water tank LV is full, and is disposed to be retained between the water surface and the water surface -26- (23) (23) 1252102 A gap of a predetermined distance. For this reason, in the case of another failure to prevent the reverse flow machine or an abnormality at the time of water cut, water (warm water) in the water tank flows into the open end of the supply passage for any reason such as a negative pressure, that is, In the case of going backflow, it is possible to prevent such a situation. For this reason, it is possible to prevent the sewage (the tap water that is in contact with the outside of the water pipe) and to protect the water supply pipe of the tap water. Further, in the preparation of the operation, in general, since it is prepared to sterilize bacteria and the like, it is possible to provide a warmth system which is also considered in the sanitary surface. By automating the high-temperature sterilization, the user can save the labor of sweeping the water tank and the like for the countermeasures of the bacteria, and provide the excellent triple warming system that is easy to use. In addition, as a temperature control, it is easy to control the temperature by using the temperature of the vapor from the air outlet, and the so-called user's sensibility can be improved and lowered by adjusting the current temperature. The temperature specification method is adopted to adjust the vapor temperature in the bath simply and accurately. Further, the configuration of the steam generating device 1 1 of the above embodiment can be further changed into various forms. For example, by attaching the vibration-damping material to the outer surface of the water tank (the storage tank 31 and the heat exchange water tank 32) and inserting the molded steel material (SUS) into the separator 73, it is possible to accelerate the warm water from the injection nozzle 36. The low cycle noise generated by the injection is reduced. Moreover, when the preparation time of the heat source or the time of high-temperature sterilization is shortened, the heat insulating material is attached to the outer surface of the water tank 30, and the waterproof area -27-(24) (24) 1252102 (sink 30 and waterproof) The air volume of the space between the covers 20 is designed to be effective to a minimum. Further, the present invention is not limited to the configuration of the above-described embodiment, and it is of course possible to change various forms depending on the scope of the patent application. [Industrial Applicability] As described above, the steam generating device of the present invention can be easily installed in a bath for use in a general household or the like, and can be easily installed in a narrow space. For this reason, if the steam generating device is used, the bath can be used as a warm bath and can be used simply and efficiently.
