[0005]
[Problems to be solved by the invention]
In such a conventional humidifier, the hot water boiled on the upper surface of the radiator 102 descends along the wall surface of the thermal diffusion prevention cylinder 109 and is mixed with the cold water on the side lower surface of the heating element 107 to dissipate heat. A region of nucleate boiling always occurs on the side. It is generally known that the boiling sound during nucleate boiling prior to film boiling is much louder than the boiling sound during film boiling that is completely boiling during the process up to boiling. Since there is a state, there is a problem that the boiling sound is always large, and it is required to reduce the boiling sound.
[0006]
This invention solves such a conventional subject, and it aims at providing the humidifier with a small boiling sound.
[0007]
In addition, calcium and magnesium contained in the water become evaporation residues and adhere to the surface of the heat dissipating body 102 and the heat diffusion prevention cylinder 109.

A possible structure is required.
[0012]
The present invention solves such a conventional problem, and an object thereof is to provide an easy-to-use humidifier that can be used continuously for a long period of time without frequent cleaning.
[0013]
Moreover, even if cold water and hot water are blocked, heat is dissipated from the hot water to the cold water through the shielding ribs, heat is transferred to the cold water in the water tank 104, and heat is dissipated from the main body 101 into the air. There is a problem that it is not used, and a structure with high heating efficiency is required.
[0014]
The present invention solves such a conventional problem, and an object of the present invention is to provide a humidifier with high heating efficiency that suppresses heat that escapes from a rib for preventing nucleate boiling and escapes.

【Example】
(Example 1)
As shown in FIG. 1 and FIG. 2, a convex heat radiating body 4 having a heating element 3 is protruded from the bottom of a water tank 2 provided in the main body 1, and a tank for supplying water to the water tank 2 at a constant water level. 5 is detachably mounted. A heat diffusion preventing cylinder 6 is provided around the heat radiating body 4, and an annular body 6 a located below the heat generating body 3 and close to the outer periphery of the heat radiating body 4 is integrally provided on the inner periphery of the heat diffusion preventing cylinder 6. It has been. The upper part of the heat diffusion preventing cylinder 6 protrudes upward from the water surface, and the lower part is placed on the bottom surface of the water tank 2. When the water level in the water tank 2 is lowered, the float 7 is also lowered, and the lead switch 8 is activated to stop the heating element 3 safely. The fan motor 9 conveys steam generated by the heat radiating body 4 to the outside of the main body 1.
[0030]
In the above configuration, water supplied from the tank 5 is supplied to the radiator 4 through the water tank 2. The water heated by the radiator 4 is turned into steam and blown into the room together with the air from the fan motor 9. At this time, the hot water heated by the radiator 4 convects and tries to mix with cold water below the heating element 3, but the convection is blocked by the annular body 6 a of the heat diffusion prevention cylinder 6, and the film boiling state is caused. Since it keeps maintaining, it can prevent becoming a nucleate boiling state with a loud boiling sound.
[0031]
(Example 2)
As shown in FIGS. 3 and 4, a heat diffusion preventing cylinder 10 is provided around the radiator 4, and the upper part of the heat diffusion preventing cylinder 10 protrudes above the water surface and the lower part is placed on the bottom surface of the water tank 2. ing. An annular body 11 is detachably fixed to the heat diffusion preventing cylinder 10 so as to be in close contact with the inner periphery of the heat diffusion preventing cylinder 10 and close to the outer periphery of the radiator 4. The annular body 11 is a synthetic resin molded product in which synthetic rubber is mixed, and is formed of an elastic body so as to expand and contract when attached and detached.
[0032]
With the above configuration, the hot water heated by the radiator 4 convects and tries to mix with cold water below the heating element 3, but the convection is blocked by the annular body 11 and the film boiling state is maintained. Can be prevented from becoming a large nucleate boiling state. In addition, since the annular body 11 and the heat diffusion prevention cylinder 10 can be divided, the heat diffusion prevention cylinder 10 can be formed into a simple and easy-to-clean shape, and the annular body 11 can be removed and washed so that it is easy to clean.
[0033]
(Example 3)
As shown in FIGS. 3 and 5, the thermal diffusion prevention cylinder 10 is provided with an annular body 12 that is in close contact with the inner periphery thereof and in close contact with the outer periphery of the radiator 4. A cutout 12a for water supply is provided on the 4 side.
[0034]
With the above configuration, the hot water heated by the radiator 4 convects and tries to mix with the cold water below the heating element 3, but the convection is blocked by the annular body 12 and the film boiling state is maintained. It can prevent nucleate boiling with loud sound. Further, since the annular body 12 and the heat diffusion preventing cylinder 10 are structured to be split, the heat diffusion preventing cylinder 10 can be formed into a simple and easy-to-clean shape, and the annular body 12 can be removed and washed so that it is easy to clean. Furthermore, the annular body 12 is brought into intimate contact with the inner periphery of the thermal diffusion prevention cylinder 10 and the outer periphery of the radiator 4, and water is supplied only from the notch 12a for water supply, thereby minimizing the contact area of hot water and cold water. Loss can be reduced.

(Example 4)
As shown in FIGS. 3, 6, and 7, the water supply notch 12 a of the annular body 12 is positioned in the vicinity of the non-heat generating portion 3 a of the heating element 3.
[0036]
With the above configuration, in the vicinity of the high temperature portion (heat generating portion) of the radiator 4, calcium bicarbonate, magnesium bicarbonate, and the like release carbon dioxide and precipitate as evaporation residues, which are easily deposited and fixed. By avoiding the high temperature portion of the radiator 4, the water supply notch 12 a of the annular body 12 is disposed near the low temperature portion of the radiator 4, that is, in the vicinity of the non-heat generating portion (terminal side of the heating element) 3 a of the heating element 3. The notch 12a is not exposed to a high temperature, and the evaporation residue is relatively less likely to deposit around it. Therefore, the evaporation residue does not accumulate and block the water supply cutout 12a, and can be used stably for a long time.

(Example 5)
As shown in FIGS. 8 and 9, a substantially cylindrical annular body 13 is detachably inserted between the outer periphery of the radiator 4 and the inner periphery of the thermal diffusion prevention cylinder 10 below the heating element 3. A water supply groove 13a is formed on the side of the radiator 13 on the annular body 13. The annular body 13 is sized to fill the space between the radiator 4 and the thermal diffusion prevention cylinder 10.
[0038]
With the above configuration, the hot water heated by the radiator 4 convects and tries to mix with the cold water below the heating element 3, but the convection is blocked by the annular body 13 and the film boiling state is maintained. It can prevent nucleate boiling with loud sound. Further, since the annular body 13 is entirely inserted into the space between the heat radiating body 4 and the heat diffusion prevention cylinder 10 below the heating element 3, the volume and thickness of the annular body 13 itself are increased, and the heat insulation effect is also obtained. It has become a big thing. Therefore, the amount of heat transferred from the hot water to the cold water through the annular body 13 is extremely small, and heat loss can be reduced and the humidification efficiency can be improved.

It is possible to prevent hot water and cold water below the heating element from mixing and lowering to a boiling point or less to become a nucleate boiling state, and to maintain a film boiling state at all times, so that an advantageous effect of reducing boiling noise during operation can be obtained.
[0041]
In addition, by providing an annular body close to the outer periphery of the heat dissipating body and in close contact with the inner periphery of the heat diffusion prevention tube at a position below the heat generating element, hot water on the upper surface of the heat generating element and cold water below the heat generating element are mixed. It is possible to prevent nucleate boiling from becoming below the boiling point, and to maintain the film boiling state at all times, so that the boiling noise during operation can be reduced, and the heat diffusion prevention cylinder and the annular body can be attached and detached, thereby improving the cleaning performance. The advantageous effect of improving is obtained.
[0042]
Also, the contact area of hot water and cold water is minimized by providing an annular body in close contact with the outer periphery of the radiator and the inner periphery of the heat diffusion prevention cylinder and with a water supply notch on the radiator side at a position below the heater. An advantageous effect is obtained in that the heating efficiency can be improved by suppressing thermal diffusion.
[0043]
In addition, by providing an annular water supply notch on the non-heating part of the heating element (on the terminal side of the heating element), it is possible to prevent evaporation residue from closing the water supply notch and making it impossible to supply water. This is advantageous in that it can be operated continuously for a long time without frequent cleaning.
[0044]
Further, by providing a substantially cylindrical annular body inserted between the outer periphery of the heat radiating body and the inner periphery of the heat diffusion preventing cylinder at a position below the heat generating body and having a water supply groove on the heat radiating body side, By increasing the volume of the annular body that blocks cold water, there is an advantageous effect that the heating efficiency can be further improved by suppressing heat escaping through the annular body.
