Description

  The present invention relates to a humidifying mechanism of a humidifying device for air humidification that evaporates water to generate humidified air.

  Conventionally, as a method of humidifying the air of this type of humidifier, water in an upper open container is heated by a heating element to evaporate, and ultrasonic waves are applied to the water to disperse fine water droplets in the air and the water droplets. There is a method to evaporate the natural gas.

  The heating element heating method consumes electric energy to heat the container and the entire amount of water because it heats the entire amount of water in the container and the container, regardless of the heating method, such as electrical resistance heating. In particular, when the humidifier is movable, when the humidifier falls down, a large amount of water in the container heated to hot water flows out of the humidifier. There is a possibility that the user may be burned and there is a safety concern, and the concentration of inorganic substances such as calcium and magnesium contained in the water increases due to evaporation of the water, so that the water concentration exceeds the concentration at which the inorganic substances precipitate. When the material evaporates, inorganic substances are deposited inside the container, and in the case of repeated use over a long period of time, hard deposits form inside the container and become dirty, resulting in low hygiene due to bacteria generated in the deposit. Or cleaning there is a problem with the Do not difficult to.

  In addition, the method using ultrasonic waves is efficient in that the water in the container is directly dispersed as fine water droplets by ultrasonic waves, but the water droplets that are scattered vary in the rate of vaporization in the air. Therefore, when dew condensation occurs around the humidifier, and harmful bacteria such as Legionella bacteria occur in the water in the container, the harmful bacteria are directly scattered in the air, and Similarly, there are problems such as the possibility of white powder being generated around the humidifier by scattering inorganic substances such as calcium and magnesium contained in water.

  As a humidifying mechanism for improving such a problem, a sheet heating element that generates heat by electric energy by energizing with the buoyancy adjusted so that the water surface is covered with a thickness of several millimeters on the water surface stored in the container. By heating the small amount of water above the surface heating element by evaporating it and evaporating it, the wasteful energy is not consumed and a small amount of water is generated. The amount of hot water that flows when the humidifier falls over is reduced to a small level by heating it, and further, the evaporation of water evaporates and the generation of white powder and harmful bacteria are scattered around the humidifier. There is also known a method that does not (see, for example, Patent Document 1).

  Hereinafter, the humidifying mechanism will be described with reference to FIG.

  As shown in FIG. 15, side walls 102, 103, 104, and 105 are provided on the periphery of the planar heating element 101, a plurality of notches 106 are provided on the opposite side walls 102 and 104, and the outer surfaces of the side walls 103 and 105 are provided. A pair of floats 107 made of a suitable material such as a synthetic resin foam of a hollow cylindrical body is attached, and a lead wire 109 connected to a resistance wire 108 that generates heat when energized in the planar heating element 101 is connected to a water surface 110. The float buoyancy is adjusted so that a thin layer 111 of water having a depth of 1 mm to several mm covers the upper portion of the sheet heating element 101 in a state where the sheet heating element 101 is floated on the resistance wire 108 of the sheet heating element 101. Efficient and safe by evaporating and evaporating a part of water on the water surface 110 in the container by heating the thin layer 111 of water by applying electric power through the lead wire 109 to generate heat, One has been to generate humidified air so as not to scatter occurrence of condensation and white powder to the surrounding, the harmful bacteria.

Japanese Patent No. 3026882

  In such a conventional humidifying mechanism, side walls 102, 103, 104, 105 are set up on the periphery of the planar heating element 101 on which the resistance wire 108 is arranged, and a plurality of notches 106 are provided on the opposite side wall 102 and side wall 104. The float buoyancy of the float was adjusted so that a thin layer 111 of water of several mm covered the surface heating element 101 with the float 107 attached to the outer surfaces of the remaining side walls 103 and 105 on the water surface 110. Since the configuration is such that humidified air is generated by evaporating the water in the portion of the water surface 110 of the container by applying power to the resistance wire 108 and heating the thin layer 111 of water, the planar heating element 101 The heated water thin layer 111 spreads over the water surface 110 of the entire container around the sheet heating element 101 through a plurality of notches 106 provided in the side wall 102 and the side wall 104, Since heat is diffused from the water surface 110 to the water in the entire container by conduction, the entire water in the container is heated over time, so that humid air is generated by heating a small amount of water in only the thin layer 111 of water. More energy is consumed than the entire water in the container is deprived of heating, and since the entire water in the container is heated in long-time use, it is heated when the humidifier falls over. Since a large amount of water that has become hot water flows out of the humidifying device, there is a problem that safety concerns that may cause the user to burn may not be resolved.

  Accordingly, the present invention solves the above-described conventional problems, and does not consume more wasted energy by appropriately heating a small amount of water necessary for humidification, and the outflow amount of hot water when the humidifier falls over It aims at providing the humidification mechanism which can improve safety | security by making further small quantity.

In order to achieve this object, a humidifying device according to the present invention is a humidifying device including a floating body heating humidifying mechanism and a blower, and the floating body overheating humidifying mechanism includes an open end. A container configured to store water by opening upward, a container body configured to cover the open end, and to form an opening having an opening area smaller than the open end at an upper portion; and the interior of the container body Is a floating body with a thickness defined in the longitudinal direction that is made of a heat insulating material that does not permeate liquid floating in water due to its own buoyancy, and in the state where it floats in water, the recessed pot is always upward, A floating body configured to adjust the buoyancy so that the heating means disposed in the hollow pot portion is immersed in water by supplying water only through the hollow pot portion, and the hollow pot portion disposed above the floating body, , A part of the bottom of the hollow pot and under the floating body A heat transfer path that connects the heat generation means for generating humid air by heating and evaporating the water disposed in the hollow pot portion by electrical conduction, and the heat generation means connected inside the container body An electrical wiring that exposes the electrically conductive terminal to the outside of the container lid and conducts electricity from the outside of the container body to the heat generating means, and the air blower is disposed in the opening and air inside the container body Air blowing means for sucking out and blowing in one direction outside, contact electrical conduction means for contacting and connecting the conductive terminal to the outside of the container lid, and power supply for supplying power from an external power source to the air blowing means and the conductive terminal A humidifying device in which the air blower is detachably attached to the container lid, thereby achieving the intended purpose.

According to the present invention , in the state where water for humidification is stored inside the container body, the heating target of the heat generating means is always only water supplied to the recessed pot portion from below the floating body through the water conduit, Since the floating body is composed of a heat insulating material, the heating energy of the heating means when electricity is conducted from the outside of the container body through the electrical wiring is difficult to disperse around the floating body. It is possible to obtain an effect that safer and more efficient humidification can be performed by heating only the water inside the hollow pot portion in which the heating of the entire water stored in the inside is suppressed.

The humidifying device according to claim 1 of the present invention is a humidifying device including a floating body heating humidifying mechanism and a blower, and the floating body overheating humidifying mechanism includes an open end and opens upward. A container configured to store water, a container cover configured to cover the open end and form an opening having an opening area smaller than the open end at an upper portion, and water by its own buoyancy inside the container body It is a floating body with a thickness defined in the vertical direction that is made of a heat insulating material that does not permeate the liquid floating in the water.It is always in the upward direction when it is floated in water, and only through the water conduit to the concave pot A floating body configured to adjust the buoyancy so that the heat generating means disposed in the hollow pot portion is immersed in water by supplying water, the hollow pot section disposed above the floating body, and the hollow pot section A water conduit that connects a part of the bottom surface and the lower part of the floating body, The heating means for generating humid air by heating and evaporating water disposed in the interior of the recess pot by electrical conduction, and a conductive terminal connected to the heating means in the container body are connected to the container lid. An electrical wiring that is exposed to the outside of the container body and conducts electricity from the outside of the container body to the heat generating means, and the blower device is disposed in the opening and sucks air inside the container body to A blowing means that blows out in a direction; a contact electrical conduction means that contacts and connects the conductive terminal to the outside of the container lid; and a power supply introduction unit that supplies electric power from an external power source to the blowing means and the conductive terminal. The apparatus was made detachable from the container lid .

  Thereby, in the state where water for humidification is stored inside the container body, the heating target of the heat generating means is always only water supplied from the lower part of the floating body to the hollow portion through the water conduit, and the floating body is Because it is composed of a heat insulating material, the heating energy of the heating means when electricity is conducted from the outside of the container body through the electrical wiring is difficult to disperse around the floating body. There is an effect that it is possible to perform safer and more efficient humidification by heating only the water inside the recessed pot portion that suppresses the heating of the entire stored water.

Further, the humidifying device according to claim 2 does not restrict the vertical movement of the floating body with respect to the container body in a state where the floating body is disposed inside the container body in the floating body heating and humidifying mechanism, but the rotation operation in a substantially horizontal plane is not performed. You may make it the structure provided with the floating body rotation operation | movement prevention means to regulate. Thus, when the floating body rotates with respect to the container body in a substantially horizontal plane, the rotating operation is restricted by the floating body rotation operation preventing means, so that the electric wiring is not twisted. Even in long-term use, the electrical wiring is unlikely to break, and the function as a humidifying device can be maintained for a long period of time, so that the reliability can be further improved.

Further, the humidifying device according to claim 3 includes heating element water exposure means for exposing the entire heating means on the water surface when the water level inside the container body falls below a predetermined water depth in the floating body heating humidification mechanism. A configuration may be used.

  As a result, when the water level inside the container body falls below a predetermined depth due to the progress of humidification, the entire heating means is exposed on the water surface by the heating element water exposure means, and the subsequent evaporation of water stops. Since the scale deposition due to the complete evaporation is suppressed, the care can be simplified, and the reliability and quality can be improved in the long-term use.

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

(Embodiment 1)
As shown in FIG. 1, a container body 1 for storing water for humidification, which is a main part of a humidifying mechanism, has a hollow inside and a container 1a having an open end 1b opened upward, and the container 1a. A container lid 2 provided with a joint 2a having a diameter slightly smaller than that of the open end 1b is press-fitted into the open end 1b and fixed.

  The container lid packing 3 made of an elastic material is sandwiched between the joint portion of the open end 1b and the container lid 2 to prevent water leakage from the joint portion 2a.

  By disposing a floating body 4 that is movable and has a thickness in the vertical direction inside the container 1a, the floating body 4 is floated in the state where the humidified water 5 that is water for humidification is stored inside the container body 1. The body 4 is made to float in the humidified water 5.

  Above the container lid 2, a container lid opening 6 having an opening area smaller than the open end 1b is provided so as to protrude upward from the container lid 2 so that the internal air can be discharged to the outside of the container body 1. Thus, the floating body 4 is placed inside the container body 1.

  As shown in FIG. 3, a hollow portion 7 is provided by recessing a part above the floating body 4, and a space is formed between a part of the bottom surface of the hollow portion 7 and the lower portion of the floating body 4. The water conduit 8 is provided.

  In a state where the humidified water 5 is stored inside the container body 1 and the floating body 4 floats in the humidified water 5, as shown in FIG. 1, the humidified water enters the pot portion 7 that is recessed from below the floating body 4 through the water conduit 8. 5 is supplied.

  In addition, as shown in FIG. 3, when electricity is applied to the inside of the recessed pot portion 7 formed above the floating body 4, heat is generated by the energy of electricity, and the humidified water 5 is heated and boiled by this heat generation to generate water vapor. Thus, the heat generating means 9 for generating humid air is fixedly arranged.

  In addition, by moving the center of gravity of the floating body 4 downward below the floating body 4, the recessed pot portion 7 is always placed in the upward direction in a state where the floating body 4 is suspended in the humidifying water 5. A weight 10 for adjusting the sinking by changing the buoyancy of the floating body 4 is fixedly attached.

  One end of an electric wire 11 in which an electric wire for conducting electricity is covered with an insulator is fixedly connected to the heat generating means 9. Further, as shown in FIG. 2, a conductive conductive terminal 12 is connected to the other end of the electrical wiring 11, and an insulator is used together with the clothing of the electrical wiring 11 so that a part of the conductive terminal 12 is exposed to the outside. A molded terminal block 13 is arranged.

  As shown in FIG. 1, the terminal block 13 is disposed such that a part of the conductive terminal 12 is exposed to the outside of the container body 1, and the terminal block 13 is press-fitted by providing a hole 2 b in the container lid 2. In addition, a concave portion (not shown) is provided in the joint portion 2a of the container lid 2, and the terminal block 13 is sandwiched and adhered in a state where the container lid 2 is fixed to the container 1a. The terminal block 13 may be protruded.

  In this way, if the power source is connected from the outside of the container body 1 to the conductive terminal 12 exposed from the terminal block 13, the heating means 9 generates heat due to the electrical energy conducted through the electrical wiring 11, In the present embodiment, the power source is not limited in configuration and will not be described in detail.

  Here, the container 1a shown in FIG. 1 is made of a transparent or translucent member so that the amount of the humidified water 5 inside can be easily confirmed, such as polypropylene and polycarbonate. These are formed by molding with a heat-resistant resin material or a glass material with enhanced heat resistance.

  Further, by providing a window made of a transparent or translucent member in a part of the container 1a so that the amount of the humidified water 5 inside can be confirmed, a corrosion-resistant metal such as stainless steel, It is also possible to form with ceramics.

  Furthermore, the container 1a can also suppress the temperature rise of the outer surface of the container 1a by filling the inside with dry air or nitrogen gas as a double molding, or increasing the heat insulation as a vacuum.

  Therefore, the container lid 2 is also made of a highly heat-resistant and robust member, for example, formed by molding with a heat-resistant resin material such as polypropylene or polycarbonate, or a glass material with enhanced heat resistance. It is.

  Further, since the container lid 2 does not need to have a particularly transparent or translucent performance, it can be made of a corrosion-resistant metal such as stainless steel or earthenware.

  Further, the container lid packing 3 is constituted by a member that retains elasticity even during long-term use and has excellent weather resistance. For example, the container lid packing 3 is formed by molding into a thin cylindrical shape using a silicon rubber material.

  The floating body 4 floats in water and is composed of a member having excellent heat insulation performance, weather resistance, and heat resistance. For example, the floating body 4 is foamed or hollow with a resin such as polycarbonate, epoxy, or unsaturated polyester. It is formed by adjusting the buoyancy of forming and floating in water.

  The heating means 9 heats and boiles the humidified water 5 by generating heat by applying electric energy. In particular, it has high weather resistance and can be stably heated in the water without leaking for a long period of time, and high safety that does not lead to ignition or combustion even in unexpected situations such as heating without the humidified water 5 is required. It is what

  Therefore, the heat generating means 9 shown in FIG. 5 has its own temperature at this Curie temperature regardless of the applied voltage or the surrounding conditions because the resistance value rapidly increases when, for example, the Curie temperature exceeds a specific temperature. It is desirable to use the PTC resistor 14 whose heat is adjusted as the main component of the heat generation.

  Furthermore, the entire PTC resistor 14 is made of Teflon (registered trademark) as a resin material having excellent insulation performance, heat resistance exceeding 100 ° C., and weather resistance that does not cause corrosion or cracking with water or heat. Or it molds using a polyimide-type resin material.

  The entire PTC resistor 14 is hermetically sealed by molding so as to separate and insulate from water.

  Here, the specific Curie temperature of the PTC resistor 14 is desirably selected from 110 ° C. to 130 ° C. in consideration of the main function of water boiling and prevention of generation of smoke and ignition of the heat-resistant resin due to high temperature. .

  Here, as described above, the heat generating means 9 has a main function to heat and boil the humidified water 5 by heat generated by applying electric energy in order to generate humidified air. A calorific value (electric power) depending on the evaporation energy of water necessary to obtain the humidified amount is required.

  The necessary heat generation amount of the heat generating means 9 is that the latent heat of vaporization in the standard atmospheric pressure of water is about 2257 kJ / kg (about 540 kcal / kg). Therefore, for example, a small humidifier for obtaining a humidification amount of 100 cc per hour Assuming that, a heat generation amount of about 63 W / sec, that is, heating performance of power consumption is required.

  The heat generating means 9 is required to generate humid air that responds quickly to the application of electrical energy. If the power consumption is the same, the smaller the surface area in contact with the humidified water 5 is, the more the heat dispersion is suppressed and the increase in the surface temperature with respect to the application of power can be accelerated, so the heat generating means 9 is desirably as small as possible. It is.

  However, in general, a heating element by energization of electricity is limited in power density per unit area based on heat conductivity with respect to a substance to be heated and physical durability of the heating element. The size will also be specified.

In an underwater heating element, water has a relatively high heat transfer property and the ambient temperature is kept below 100 ° C by evaporation, so the power density can be set to a relatively high value of around 6 W / cm ^2. However, in consideration of ensuring reliability over a long period of time, about 3 W / cm ² is desirable.

That is, as described above, the surface area of the heat generating means 9 for which a heat generation amount of 63 W / sec is required is 21 cm ^{2. When} the heat generating means 9 has the cylindrical shape of this embodiment and the height is 0.5 cm, the heat generating means 9 From the surface area calculation, the diameter of the circular surface is configured to be about 3.2 cm.

  As already described, the heat generating means 9 is formed by a resin mold. At the time of molding, the electrical wiring 11 is also connected to the PTC resistor 14, and the entire clothing is molded in a wired state, thereby preventing water from entering the interior and improving the insulation.

  The electrical wiring 11 is covered with Teflon (registered trademark), polyimide, or a silicon-based resin material because it is necessary to consider long-term use in contact with water, similar to the heat generating means 9. It is a thing to choose. The terminal block 13 connected to one end of the electric wiring 11 is shaped by molding using an elastic body (for example, silicon rubber material) having excellent weather resistance, and is molded from above the clothing of the electric wiring 11. By molding, water is prevented from entering the inside of the electric wiring 11 and long-term reliability is improved.

  In addition, as shown in FIG. 5, the heat generating means 9 is provided with a plurality of cylindrical fixed convex portions 15 below the heat generating means 9 when resin molding is performed.

  Further, as shown in FIG. 3, a hole in which the fixed convex portion 15 enters is provided in the bottom portion of the hollow portion 7 above the floating body 4. This hole is slightly narrowed in the tip direction, so that the fixing projection 15 is press-fitted and the heat generating means 9 is fixed to the floating body 4.

  Further, a flange 16 having a slightly larger diameter than the fixed protrusion 15 is provided at the base of the fixed protrusion 15 below the heat generating means 9.

  As a result, when the heat generating means 9 is fixed to the hollow pot 7, a gap defined by the height of the flange 16 is formed between the lower surface of the heat generating means 9 and the hollow pot 7, and the water guide path is formed by the heat generating means 9. It can be set as the structure which 8 holes are not obstruct | occluded.

  In a state where the floating body 4 is suspended in the humidified water 5, the humidifying water 5 is supplied from the lower side of the floating body 4 through the water guide path 8 to the recessed pot portion 7 so that the heating means 9 is immersed in the humidified water 5. ing.

  Here, the hollow pot portion 7 is a portion that constitutes a water boiling pot for generating humid air by heating and boiling the humidified water 5 supplied through the water conduit 8 by the heating means 9 and evaporating it. It is necessary to have heat resistance exceeding 100 ° C. as well as heat insulation.

  Therefore, when the floating body 4 is also composed of a member having a heat resistance performance exceeding 100 ° C., no special consideration is required. However, when considering the use of a member that does not satisfy the above heat resistance performance or further improvement in reliability over a long period of time, the mold is made of the same resin material as Teflon (registered trademark) or polyimide based on the mold material of the heating means 9. A structure formed by molding may be assembled to the floating body 4.

  Further, the hollow pot portion 7 does not stagnate the supply of the humidified water 5 around the heat generating means 9 so that humid air is generated in response to the application of electric energy to the heat generating means 9, and the heat generating means 9. It is necessary to make it the magnitude | size which reduces the total amount of the humidification water 5 of the circumference | surroundings as much as possible.

  Therefore, for example, when the circular diameter of the heat generating means 9 requiring a heat generation amount of 63 W / second as described above is about 3.2 cm and a cylinder having a height of 0.5 cm, the size of the hollow pot portion 7 is large. Has a diameter of 4 cm to 5 cm and a depth of 1.5 cm so that the entire heating means 9 sinks into the humidified water 5 by about 2 mm when the floating body 4 with adjusted buoyancy is suspended in the humidified water 5. It consists of front and back.

  Here, the weight 10 for changing the buoyancy of the floating body 4 to adjust the sinking into the humidified water 5 is a mass per unit volume as compared with the water that does not change the humidified water 5 without causing rust or corrosion in the water. Is made of heavy material. For example, a metal material such as stainless steel or a ceramic material such as ferrite formed into a cylindrical shape is used.

  In addition, the adjustment of the submerged state of the floating body 4 with respect to the humidified water 5 is performed by changing the buoyancy of the floating body 4 itself. That is, in the entire configuration in which the heating means 9 and the weight 10 are attached to the floating body 4, the entire heating means 9 disposed inside the recessed pot portion 7 when the floating body 4 is suspended in the humidified water 5 serves as a water conduit. The weight of the weight 10 is adjusted so that it is immersed in a water depth of about 2 mm with only the humidified water 5 supplied through 8.

  Therefore, in the entire state of the floating body 4 in which only the heating means 9 is attached to the floating body 4, the entire heating body 9 is immersed in only the humidified water 5 supplied through the water conduit 8. When the weight can be adjusted, the weight 10 need not be attached.

  Now, since there is a possibility of water adhering to the exposed surface of the conductive terminal 12 exposed from the tip of the terminal block 13 to the outside of the container body 1, there is a concern that the conductivity is deteriorated due to alteration or oxidative corrosion. For example, it is possible to maintain the conductive performance for a long period of time by plating with a metal material of gold or gold-silver alloy having excellent corrosion resistance.

  According to such a configuration, first, the heat generating means 9 is attached to the recessed pot portion 7 above the floating body 4 and the weight 10 is attached to the lower portion so as to be integrated into the container 1a with the heat generating means 9 upward. Insert and install. The terminal block 13 connected to the electric wiring 11 molded in the heat generating means 9 has a hole 2b formed in the container lid 2, or an exposed portion of the conductive terminal 12 in which a recess (not shown) is molded in the terminal block 13. After press-fitting and fixing to the outside of the container lid 2, the container lid 2 is sandwiched by press-fitting the container lid packing 3 into the open end 1 b above the container 1 a and joined to form a humidifying mechanism. ing.

  As described above, the floating body 4 to which the heating means 9 and the weight 10 are attached is immersed in only the humidified water 5 supplied through the water conduit 8 in the entirety of the heating means 9 disposed in the hollow pot portion 7 in the water. Since the weight of the weight 10 is adjusted to adjust the overall buoyancy, water for humidification is poured into the container body 1 from the container lid opening 6 provided in the container lid 2 and the humidified water 5 In a state in which the floating body 4 is stored, the floating body 4 always floats in the humidified water 5 in a state where the entire heating means 9 is immersed only in the humidified water 5 supplied through the water conduit 8.

  When the power source is connected from the outside of the container body 1 to the conductive terminal 12 in a state where the floating body 4 is floated in the humidified water 5 as described above, the power of the power source is connected to the PTC resistor 14 via the electric wiring 11. Is applied.

  The PTC resistor 14 generates heat near the Curie temperature due to the supplied electric energy, and the heat generation causes the PTC resistor 14 to heat only the humidified water 5 accumulated in the hollow portion 7 and insulated from the surroundings. The water is efficiently produced by boiling.

  That is, the humidified water 5 accumulated in the hollow pot portion 7 is boiled to become water vapor, and becomes humidified air from the container lid opening 6 provided in the container lid 2 and is discharged to the outside of the container body 1. At the same time, the surrounding air is gradually lost while humidifying. On the other hand, the humidified water 5 lost by evaporation from the hollow pot portion 7 is supplied from the lower side of the floating body 4 through the water conduit 8 to the state where the entire heat generating means 9 is immersed. In other words, the humidified water 5 stored inside the container body 1 is consumed while maintaining the level of the humidified water 5 accumulated in the recessed pot portion 7 so as not to overflow.

  Further, the humidified water 5 in the recessed pot portion 7 heated at this time does not overflow from the recessed pot portion 7 to the outside by convection after being heated, and does not flow out from the lower water conduit 8. .

  In particular, the outflow from the water conduit 8 is based on the natural principle that the heated fluid at the top in the same substance does not move to the bottom of the unheated fluid.

  That is, the heat energy of the heat generating means 9 is merely dispersed in the humidified water 5 outside the recessed pot portion 7 through heat conduction to the humidified water 5 inside the water conduit 8, and most of the energy stored in the container body 1 is stored. It will be supplied to the humidified water 5.

  That is, since the heat energy of the heating means 9 is consumed only for evaporating the water in the hollow pot portion 7, efficient humidification can be performed.

  As described above, when the humidified water 5 stored inside the container body 1 is heated and sequentially consumed, the floating position of the floating body 4 is also lowered due to the decrease in the humidified water 5 inside the container body 1. Finally, the bottom surface of the floating body 4 comes into contact with the bottom surface inside the container 1a. Then, if the humidifying water 5 does not fill the position of the heat generating means 9 disposed above the floating body 4, the humidification is stopped.

  From the above, in the state where the humidified water 5 is stored inside the container body 1, the humidified water 5 heated by the heat generating means 9 is always supplied from the lower side of the floating body 4 to the recessed pot portion 7 through the water conduit 8. Only humidified water 5 is used. On the other hand, since the floating body 4 is made of a heat insulating material, the heat energy of the heat generating means 9 is difficult to disperse around the floating body 4.

  That is, the humidification water 5 stored inside the container body 1 can be efficiently humidified while suppressing the overall heating of the humidification water 5, and the humidification water 5 inside the container body 1 leaks to the outside even if the apparatus falls. Even when the water is taken out, the water that is heated and boiled is only a small amount of the humidified water 5 in the hollow pot portion 7. Therefore, a small amount of the humidified water 5 in the hollow pot portion 7 is dispersed outside the container body 1 or mixed with the majority of the unheated humidified water 5 inside the container body 1 to change the temperature. Therefore, it is possible to perform humidification with higher safety, which is less likely to cause burns due to contact with the user.

  In the present embodiment, the container lid 2 is press-fitted into the open end 1b with the container lid packing 3 sandwiched between the open end 1b above the container 1a and fixed, thereby preventing water leakage. The body 1 is configured to be closed. However, if a screw thread that engages the opening surface of the container 1a and the container lid 2 with the joint portion is screwed into the container 1a and the container lid 2 is screwed and tightened, the mechanical fixing method is more effective. Needless to say, the container lid 2 can be firmly and securely fixed to the container 1a.

  Further, the floating body 4 is suspended in the humidified water 5 inside the container 1 a constituting the container body 1, and is humidified by heating and evaporating the humidified water 5 by the heating means 9 disposed above the floating body 4. It is the structure to perform, Comprising: The floating body 4 was floated freely inside the container 1a. In this case, since there is no restriction on the operation of the floating body 4 rotating in a substantially horizontal plane with respect to the container 1a, the electric wiring 11 that supplies power to the heat generating means 9 may be twisted. When the electric wiring 11 is disconnected, the function as a humidifying device is lost, and there is a concern about the reliability of long-term use.

  6 and 7, the floating body 4 is movable in the vertical direction inside the container body 1, but the floating body 4 is substantially horizontal with respect to the container body 1. It is possible to prevent the electric wiring 11 from being twisted by providing the floating body rotation operation preventing means 17 that regulates the rotating operation.

  Here, as shown in FIG. 7 to FIG. 9, the floating body rotation operation preventing means 17 includes a groove portion 18 provided by recessing two opposing portions on the longitudinal side surface of the floating body 4, and the two locations. The support portion 19 is provided so as to protrude in the longitudinal direction of the inner surface of the container 1a entering the groove portion 18 with a gap.

  According to such a configuration, the floating body 4 rotates in a substantially horizontal plane with respect to the container 1a by inserting the floating body 4 into the container 1a with the positions of the groove portion 18 and the support portion 19 aligned. When this occurs, the rotation of the floating body 4 is restricted by the support portion 19 coming into contact with the groove portion 18 so that the electric wiring 11 is not twisted. Therefore, even when used for a long period of time, the electrical wiring 11 is unlikely to break, and the function as the humidifier can be maintained for a long period of time, so that the reliability can be further improved.

  Without providing an additional mechanism, the horizontal cross-sectional shape of the container 1a and the floating body 4 is, for example, elliptical or polygonal, in which the floating body 4 can move in the vertical direction inside the container 1a and a gap that does not rotate is provided. It goes without saying that the floating body rotation operation preventing means 17 can also be realized by adopting a structure in which the floating body 4 cannot physically rotate in a substantially horizontal plane as a similar shape.

  Further, in the present embodiment, the floating body 4 is suspended in the humidified water 5 inside the container 1a, and humidification is performed by heating and evaporating the humidified water 5 by the heating means 9 disposed above the floating body 4. However, if the generation of humidified air proceeds while the container 1a is filled with the humidified water 5, the humidified water 5 is reduced inside the container 1a due to the evaporation of moisture, but the moisture is decreased. In general, general water such as tap water contains about 100 mg of non-evaporating inorganic substances such as calcium and magnesium dissolved in 1 liter, so the concentration of non-evaporating inorganic substances gradually increases. It will be followed.

  When most of the water eventually evaporates, the inorganic substance in the water will precipitate as a solid, but the generation of humidified air that evaporates all the humidified water 5 stored in the container 1a in this way over a long period of time. Repeatedly, the solidified inorganic substance is laminated inside the container 1a such as the inner surface of the container 1a or the surface of the floating body 4, so that deposits containing very hard dust and dirt components generally called scales are formed. There are concerns about reliability and quality of long-term use, such as reducing hygiene due to bacterial growth on this scale.

  Therefore, as surrounded by the thick wavy line in FIG. 10, when the water level of the humidified water 5 inside the container 1a constituting the container body 1 falls below a predetermined depth, the entire heating means 9 is exposed on the water surface. By providing the heating element water exposure means 20, the subsequent evaporation of the humidified water 5 can be stopped.

  Here, when the heating element water exposure means 20 makes the lower surface of the floating body 4 contact the inner bottom surface of the container 1a, the heating element water exposure means 20 extends from the inner bottom surface of the container 1a to the lower surface of the heating means 9 disposed above the floating body 4. The vertical thickness of the floating body 4 itself is utilized so that the height is the same as the predetermined water depth.

  Here, the water depth specified in advance does not lead to precipitation of inorganic substances in the water as solid bodies when moisture is evaporated by advancing the generation of humidified air from the state in which the container 1a is filled with the humidified water 5. By increasing the utilization rate of the humidified water 5 that can be stored in the container 1a for the generation of the humidified air, the generation time of the humidified air for each water supply is extended as much as possible. For example, the depth is set to a depth at which 5% to 10% of the humidified water 5 that can be stored in the container 1a remains.

  According to such a configuration, the container 1a is filled with the humidified water 5 and the generation of the humidified air is advanced so that the humidified water 5 is gradually lost due to evaporation. When the water level of the humidifying water 5 falls below a predetermined water depth by the heating element water surface exposing means 20 configured to have the same thickness as the predetermined water depth, the entire heating means 9 is exposed on the water surface. Become.

  When the entire heat generating means 9 is exposed on the water surface, the subsequent evaporation of the humidified water 5 stops, and the predetermined water depth is an inorganic concentration at which inorganic substances contained in the water do not precipitate even during the progress of water evaporation. Since the humidified water 5 is set to remain, precipitation of inorganic substances inside the container 1a due to complete evaporation of the humidified water 5 is suppressed, and the interior of the container 1a is also used in repeated water supply. If the humidified water 5 remaining in the container is discarded and then supplied, the scale can be prevented from accumulating, so that care can be simplified. Therefore, reliability and quality in long-term use can be improved.

  When the water level of the humidifying water 5 falls below a predetermined water depth by the heating element water exposure means 20, the entire heating means 9 is exposed on the water surface, and when the subsequent evaporation of the humidifying water 5 is stopped, heat generation occurs. Heat generation increases due to the energy of electricity supplied by the means 9, but in the heat generation means 9 mainly composed of the PTC resistor 14, the specified Curie temperature (for example, from 110 ° C to 130 ° C) is set. As a matter of course, if the surrounding elements including the heat generating means 9 are configured in consideration of the Curie temperature, there is no problem in safety and quality.

  Further, in the heat generating means 9 mainly composed of the PTC resistor 14, the current flowing through the resistor itself is suppressed (the resistance value is increased), whereby the Curie temperature (for example, from 110 ° C. to 130 ° C.). Since the temperature rise to above is suppressed, the heat generating means 9 can be provided by separately providing a power supply switch circuit based on current detection that stops energization to the heat generating means 9 by detecting the suppressed current. It is needless to say that safety and long-term quality can be improved since the heat generation itself can be stopped.

  Further, the temperature rise of the heat generating means 9 to a predetermined value or more is detected directly (with a thermistor or the like) or indirectly (with a thermopile or the like), or the lower surface of the floating body 4 contacts the inner bottom surface of the container 1a. Is indirectly detected (a magnet is embedded in the lower part of the floating body 4 and this magnetic force is detected by a magnetic detection element embedded in the bottom surface of the container 1a). Since the heat generation of the heat generating means 9 can be stopped by separately providing a power source switch circuit based on temperature and position detection, the heat generating means 9 is provided with a temperature rise suppressing function different from that of the PTC resistor 14. Needless to say, safety and long-term quality can be further improved even when a general resistor is used.

(Embodiment 2)
11, the same components as those in FIGS. 1 to 5 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 11, this configuration sucks humidified air generated inside the container body 1 by energization of electric power into the outer casing 21 that forms the housing of the apparatus with respect to the humidifying mechanism of the first embodiment. A blowing means 22 for blowing out in one direction outside the container body 1, a contact electrical conduction means 23 configured by contact as a conduction path for conducting electricity to the heating means 9, and an outside of the blowing means 22 and the heating means 9 It is provided with a blower 25 that is configured to include a power supply introduction unit 24 that configures a power supply path from a power supply.

  The air blower 25 is configured to be detachable from the container lid opening 6 at the top of the container body 1. In the state in which the blower 25 is attached to the container body 1, the external power supplied through the power supply introduction unit 24 is connected to the heat generating means 9 by the contact conduction of the contact electrical conduction means 23 so as to be humidified as a unit. It is a device.

  The power supply unit 24 is connected to, for example, a general commercial power source of the unit or a power supply source 26 such as an AC adapter that reduces the voltage of the commercial power source and stabilizes the power supply unit 24. Electric power for heating by the driving and heating means 9 can be obtained from the outside of the blower 25.

  The outer shell 21 is formed of a material having sufficient strength and electrical insulation to form the casing of the apparatus. For example, the outer shell 21 is molded as a plurality of parts by molding with a resin material such as acrylonitrile butadiene styrene or polyphenylene sulfide. Assembling and constructing as a unit.

  The blowing means 22 is a general electric blower 27 that generates a flow of air in one direction by rotating an impeller and blowing air with an electric motor that generates a rotational force by supplying electric power.

  As shown in FIG. 12 and FIG. 13, the blower device 25 has an electric blower 27 arranged inside the outer shell 21 so that the blowing direction is in the horizontal direction, and at one end of the outer shell 21 that becomes the blowing direction of the electric blower 27. A blowout opening 28 for releasing the blown air to the outside is opened. Further, an intake opening 29 is opened in the outer shell 21 in the direction opposite to the blowing direction to suck outside air into the outer shell 21, and further, a route from the electric blower 27 to the blowing opening 28 below the outer shell 21. And the suction opening 30 is formed. That is, the air blown by the electric blower 27 sucks outside air from the intake opening 29 to the inside of the outer shell 21 to generate an air flow toward the blowout opening 28, and the negative pressure generated by the air flow causes the air from the suction opening 30. Also, the outside air is attracted to the inside of the outer shell 21 and is discharged from the blowout opening 28 together with the outside air sucked from the intake opening 29.

  Here, the suction opening 30 opened below the outer shell 21 constituting the air blowing means 22 is opened with a diameter slightly larger than the outer diameter of the container lid opening 6. By inserting the container lid opening 6 into 30, the blower device 25 can be detachably mounted on the container body 1.

  In addition, a cylindrical suction opening packing 31 made of an elastic body that fills the gap between the container lid opening 6 and the inside of the suction opening 30 is press-fitted and attached, so that the container is attached to the suction opening 30. When the lid opening 6 is inserted, leakage of air and water from the insertion portion is prevented, and the lid can be restrained when the blower 25 is attached to the container body 1.

  The suction opening packing 31 is composed of a member that retains elasticity even during long-term use and has excellent weather resistance. For example, the suction opening packing 31 is molded into a thin cylindrical shape using a silicon rubber material. .

  Here, the contact electrical conduction means 23 includes a terminal block slit portion 32 and a conductive crimping plate 33. As shown in FIG. 11, the terminal block slit portion 32 has a distal end of the terminal block 13 that is fixedly protruded to the outside of the container body 1 in a state where the blower 25 is attached to the container body 1. 21 is opened to the outer shell 21 so as to enter the inside of the outer shell 21. Further, as shown in FIG. 12, the conductive crimping plate 33 for supplying power to the conductive terminal 12 is located at a position in contact with the tip of the conductive terminal 12 exposed from the terminal block 13 inside the terminal block slit portion 32. It is arranged and fixed to the constituent material of the outer shell 21.

  In addition, the conductive crimping plate 33 is made of a material having conductivity and spring property. For example, a metal thin plate of copper alloy such as phosphor bronze is formed into a strip shape, and a contact portion with the conductive terminal 12 is curved. Thus, it is formed by die pressing so as to maintain a reliable contact with the conductive terminal 12 by projecting.

  Further, when the conductive crimping plate 33 is constructed by assembling the outer shell 21, for example, a seam is provided to face a part of the inner configuration of the outer shell 21, and a part of the conductive crimping plate 33 is formed at the joint. It is fixed to the outer shell 21 by being sandwiched. And in the state which attached the air blower 25 with respect to the container body 1, the reliable electrical connection between the conductive crimping board 33 and the conductive terminal 12 by the positional relationship between the elasticity which the conductive crimping board 33 has, and the conductive terminal 12 is ensured. Keep in touch.

  The conductive crimping plate 33 is electrically connected to the power supply introduction part 24 inside the outer shell 21.

  In the above-described configuration, the container lid 1 is provided to the container body 1 by inserting the container lid opening 6 into the suction opening 30 to which the suction opening packing 31 is attached. The blower 25 can be attached. In this state, the tip of the terminal block 13 enters the inside of the outer casing 21 through the terminal block slit portion 32 opened to the outer casing 21, and the conductive crimping plate 33 is exposed to the conductive terminal 12 exposed from the terminal block 13. It will be in electrical contact with the tip being pressurized.

  In the state where the conductive crimping plate 33 and the tip of the conductive terminal 12 are in electrical contact, the power of the power supply source 26 connected from the outside of the blower device 25 to the power supply introduction unit 24 provided in the blower device 25 is supplied to the heating means 9. If the humidified water 5 is stored inside the container body 1 in this state, the humidified air is generated.

  When humidified air is generated inside the container body 1, the power of the power supply source 26 is applied to the air blower 22 to the air blower 22, so that the air flow from the intake opening 29 toward the blowout opening 28 is changed. In addition, an attractive force is generated through the suction opening 30 by the negative pressure of the air generated by the electric blower 27. The humidified air generated inside the container body 1 is taken into the outer shell 21 through the joint portion between the container lid opening 6 and the suction opening 30 and is finally sucked from the intake opening 29. It will discharge | release toward one direction from the blowing opening part 28 with external air. That is, it functions as a humidifier.

  Therefore, since the user does not include the electrical component that causes destruction due to water wetting in the state in which the blower 25 is separated from the container body 1, the container body 1 directly supplies the humidified water 5. It can also be handled as a water tank that can supply water. That is, it is possible to eliminate the need for a water supply tank that simply attaches the blower 25 to the container body 1 that is supplied with the humidified water 5 and stored. Furthermore, it is possible to provide a compact humidifier that can be used by being placed near the user.

  In addition, when the container body 1 and the blower 25 are joined, unless the leading end of the terminal block 13 exposed from the container body 1 is accurately inserted into the terminal block slit 32, the conductive crimping plate 33 and the conductive terminal 12 are used. The electrical conduction to the heat generating means 9 due to the contact is not established. That is, the function as a humidifier cannot be achieved.

  Then, the humidification function can be reliably performed by providing the unevenness | corrugation and the mating surface which guide the joining of the container body 1 and the air blower 25 in the junction part of the container body 1 and the air blower 25, respectively. That is, it goes without saying that it is possible to provide a humidifying device that is easier for the user to handle than providing unevenness and mating surfaces at the joint site.

  As shown in FIG. 14, it is also possible to adopt a configuration in which the blower 25 is provided with a pedestal and the container body 1 is mounted by sliding horizontally as indicated by an arrow in the drawing. In this structure, since the positional relationship of mounting of the container body 1 with respect to the blower device 25 can be stabilized, it is needless to say that a humidifier that is easier to handle can be provided.

  In addition, it is also possible to set it as the structure which can fix the ventilation apparatus 25 with another apparatus, a part of building structure, or a screw etc., and stabilizes the positional relationship of mounting | wearing with the container body 1 with respect to the ventilation apparatus 25. Needless to say, a humidifier that is easier to handle can be provided.

  The floating body heating and humidifying mechanism and the humidifier equipped with the same according to the present invention can provide a compact humidifier with an efficient, safe, and simple configuration. It is useful as a humidifying mechanism, a humidifying device, etc. for air conditioning and air humidification.
