DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. 1 is a front sectional view of the present invention, FIG. 2 is a side sectional view, FIG. 3 is a partial front sectional view of a siphon type water dispenser, FIG. 4 is a side sectional view of a siphon type water dispenser, and FIG. It is sectional drawing of a water vessel.

The steam generating pot 1 placed below the main body 7 has a built-in electric heater 9 and is divided into upper and lower parts by a steam / water separating plate 10 made of punching metal.
1. The upper part of the steam chamber 12 is used to prevent bumping and to obtain dry steam. Then, the branch pipe 13 is taken out of the steam generating pot 1, the safety valve 14, the water level gauge 15, and the water supply pipe 16 are connected,
The upper lid 17 has a coupling port 18 for the heat exchanger 2 in the center, and four coupling bolts 2 with a body bottom plate 19 and a packing 20 sandwiched therebetween.
Tightened by 1. The lower part of the heat exchanger 2 is tightly coupled to the upper lid 17 of the steam generating pot 1 through a coupling port 18, and the upper part thereof is a leaf-shaped branch pipe 22 having a high slope and a plurality of thin tubes branched from this. 23, the thin tube 23 is further integrated into a connecting tube 24 and a connecting tube 25 is used to connect the condenser 6 with an exhalation valve.
Lead to The evaporation dish 3 is on the thin tube 23 of the heat exchanger 2 and is composed of a large number of grooves 26. The grooves 26 are covered with a hydrophilic fiber cloth 27. The water supply pipes 3 corresponding to the respective grooves 26 are provided.
The water from No. 1 permeates the entire surface of the groove 26 and adsorbs the scale left after the water is evaporated. The siphon type water supply device 4 includes a box-shaped container 29, a submersible pipe 30, a water supply pipe 31,
The submerged lever 32, the pull rod 33, the return spring 34, and the float valve 35 are attached to keep the water level in the box container 29 constant and to allow the water level to be easily confirmed on the outside of the box container 29. Attach a total of 36, and pipe 3 to this
Connected with 7. The submersion lever 32 is used to supply water to the evaporation tray 3.
Is performed by submerging the tip of the submersible pipe 30 which is a siphon pipe. The operation is performed by the pull rod 33, and the adjustment of the water supply amount is determined by the number of submerged pipes 30.
The mechanism for submerging the submerged pipe 30 is divided into a plurality of series. The water condenser 6 with the exhalation valve is attached to the outside of the main body 7 and discharges the air that has entered the primary circulation system of the steam generator 1 and the heat exchanger 2 while the apparatus is at rest. In the device, the exhalation valve 39 is connected to the upper part of the copper plate box 38, the connecting pipe 40 from the heat exchanger 2 is connected to the upper part of the side, and the water supply pipe 41 leading to the steam generator 1 is connected to the lower part of the other part. ing. The exhalation valve 39 is a high pressure valve 42 that opens at high pressure with atmospheric pressure as standard.
The low pressure valve 43 that opens at low pressure is integrated, and the high pressure valve 42 has a structure that opens at a pressure slightly lower than that of the safety valve 14 of the steam generating pot 1. Further, the low pressure valve 43 introduces the outside air when the device is stopped and the inside becomes negative pressure. The main body 7 is in the shape of a heat-insulating box, and the lower four corners are supported by the support legs 44, the blower 5 and the guide plate 45 are provided on both sides, the hot and humid air outlet 8 is provided at the center of the upper surface, and the outside air inlet 46 is provided on both sides. It has a structure in which a heat exchanger 2, an evaporating dish 3, and a siphon-type water supplier 4 are incorporated inside, a condenser 6 with an exhalation valve on the outer upper surface, and a steam generation pot 1 below.

[0007] When the operation is started and the water temperature of the steam generation pot 1 rises to reach the boiling point, evaporation is started. Initially, the primary circulation system including the steam generation pot 1, the heat exchanger 2, and the condenser with an exhalation valve 6 is filled with air corresponding to the atmospheric pressure. Therefore, the heat transfer in the heat exchanger 2 is poor, the internal air pressure rises, and air and water vapor enter the condenser 6 with an exhalation valve. Here, the water vapor component is condensed by heat radiation from the vessel wall, and the air component is released to the outside by opening the high pressure valve 42. While this action is continuously performed, most of the air component in the primary circulation system is discharged, so that the performance of the heat exchanger 2 is improved, and the amount of steam generated and the amount of dew condensation in the heat exchanger 2 are balanced. Then, the internal pressure also drops and the exhalation valve 39 closes. On the other hand, the air flow sent by the blower 5 is guided upward by the guide plate 45 and is heated while passing through the heat exchanger 2 from the lower side to the upper side.
The steam generated from the evaporating dish 3 is mixed to form a warm and humid stream containing a proper amount of moisture and is guided from the delivery port 8 to a predetermined position. The evaporating dish 3 is in intimate contact with the thin tube 23 of the heat exchanger 2 so that heat can be sufficiently transferred, and the fiber cloth 27 laid in the groove 26 is fed from the siphon type water supplier 4. The generated water is permeated and dispersed to generate steam all over the surface, and the evaporation residue is adsorbed. Humidity adjustment of the hot and humid flow is performed by the number of siphon water supply pipes 28 of the siphon water supply device 4. The water supply pipe 28 draws up water by utilizing the capillary phenomenon of the hydrophilic fiber bundle 47, and the water supply capacity is proportional to the number. Therefore, since the siphon pipe consisting of the water supply pipe 28 and the submerged pipe 30, the submersion lever 32, and the series of operating mechanisms leading to the pull rod 33 are incorporated in a plurality of series, a part or all of the siphon pipes are submerged. If so, the amount of steam generated can be controlled. In addition, there is a float valve 35 in the siphon-type water dispenser 4, which opens and closes the water supply port according to the amount of water consumed and keeps the water level in the siphon-type water dispenser 4 within a certain range. Furthermore, the water level gauge 3 is placed at a position easy to see outside the main body 7.
Since 6 is attached, visual confirmation is easy.

The present invention has the following effects. 1. Since the amount of water supplied can be adjusted with the siphon type water dispenser, the humidity will not be oversaturated. 2. Since the water supply is by siphon, there is no need for a pump, which is economical and the device is inexpensive. 3. Due to the function of the exhalation valve, air can be easily discharged and the thermal efficiency is high. 4. In addition to the water level gauge and safety valve in the steam generator, the high-pressure valve of the exhalation valve operates faster than the safety valve, resulting in higher safety.
