Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifier, and more specifically, to a steam generating container for humidifying water by storing water in a fixed amount and heating it to evaporate it to the outside, and this steam generating container. The present invention relates to a humidifier provided with a makeup water container for replenishing water with water.

[0002]

2. Description of the Related Art This type of humidifier is of a type that evaporates water under atmospheric pressure for humidification,
This is advantageous from the viewpoint of environmental hygiene because it is easy to suppress the growth of germs, which is likely to occur with other types of water handling from normal temperature to medium temperature range, such as atomizing water with ultrasonic waves.

As shown in FIG. 7, a humidifier of this kind provided by the applicant of the present invention has an intermediate bottom b formed integrally with a tubular body a at a portion slightly lower than the lower end thereof, as shown in FIG. This middle bottom b
A steam generator container d that heats water by a heater j to generate steam, and diffuses the steam to the outside through a steam pipe c fitted from above, and replenishes the water from a water supply tank e to the steam generator container d. A replenishment water container g for replenishment through a water pipe f is provided, and these are housed under an intermediate bottom b together with electric equipment (not shown) for controlling energization of a heater j.

The make-up water container g is provided with a protrusion 1 for pushing the open / close valve k provided at the opening i of the inverted water supply tank e to receive the water from the water supply tank e. The water level in the steam generating container d is maintained at the same level as the makeup water container g while being constantly supplied with water from

In the above heating type humidifier, when the steam generating container d is shallow, heating is likely to proceed and steam is generated early. However, since the entire water in the steam generating container d is heated by the heater j at once, As the whole is concentrated, the steam contacting the steam generating container d, especially in the part facing the air, the heating becomes excessive and the degree of concentration advances, and the scale easily adheres to the inner surface of the steam generating container d and accumulates. I can't stand it. Therefore, conventionally, in order to solve this problem, the steam generating container d is formed in the shape of a pot as described above to prevent the scale from adhering to the inner surface of the container due to excessive heating.

[0006]

However, since the steam generating container d of the above-mentioned conventional example is formed in the shape of a pot to prevent scale from adhering to the steam generating container, from the start of energization to the start of steam generation, as an example, There was a problem that it took 10 minutes for a slow one and 20 minutes for a slow one.

Therefore, an object of the present invention is to provide a humidifier having a simple structure which can shorten the steam generation start time after the start of energization.

[0008]

To achieve the above object, a humidifier according to the present invention stores a water from a water supply tank and a steam generating container for storing water and heating with a heater to generate steam. In a humidifier provided with a makeup water container for replenishing the steam generation container, the steam generation container has a small first heating unit that rapidly raises the temperature of water to generate steam,
The main feature is that it has a second heating unit that has a larger capacity than the first heating unit and that generates steam later than the first heating unit.

According to the above-mentioned main feature of the present invention, the water from the water supply tank is replenished to the steam generation container through the makeup water container, and the capacity of the first heating portion is small when the heater is energized. Since water is rapidly heated while suppressing the generation of scale due to excessive heating, steam can be generated early, and the second heating section has a large capacity, so a relatively large heating capacity is required. While suppressing excessive heating, the temperature can be raised slowly without generation of scale, and a large amount of steam can be generated, although later than the first heating unit. Therefore, early humidification and sufficient humidification can be satisfied while suppressing the generation of scale.

In the above structure, the first heating part and the second heating part are integrally formed so as to maintain the same water level, and a partition part having a height slightly lower than the water level is provided at the boundary part thereof, and at least the first heating part is provided. If the section is provided with a heater, only one replenishing passage is required, and water in the first heating section and water in the second heating section communicate with each other, but convection of water in each section is suppressed in each heating section by the partition section. In particular, it prevents hot water heated in the first heating part from migrating to the second heating part and facilitates early evaporation of a small amount of water in the first heating part. When the heater is provided in the first heating unit, after the water in the first heating unit is evaporated, the water in the second heating unit is delayed by thermally conducting the steam generating container integrally formed with the first heating unit. When the heater is provided separately from the first heating part and the second heating part, the vaporization is caused by turning off the power supply to the heater of the first heating part when steam starts to be generated in the second heating part. It is preferable because the power consumption can be suppressed and the scale can be prevented from adhering to the inner surface of the first heating unit.

The first heating portion and the second heating portion are arranged in a positional relationship between the central portion and the annular portion around the central portion, and the first heating portion and the second heating portion have a first positional relation.
If the heating part is formed shallower than the second heating part, even if scales are attached, the adhesion area is limited to the first heating part with a shallow bottom, so it is easy to wash from above in a short time. You can

If the first heating portion is formed at the shallow portion in the central portion, the second heating portion is formed at the deep portion in the annular portion around the central portion, and the heater is attached to the first heating portion at the central portion. , The heat of the heater quickly evaporates the water in the first heating portion located in the central portion, and at the same time, conducts heat to the annular second heating portion and stays in the second heating portion inner space below the first heating portion. The radiant heat can also heat the second heating unit to generate steam, and even one heater can efficiently generate steam.

The first heating part and the second heating part may be formed separately and each may be provided with a heater,
In the case of a structure in which water in the first and second heating sections does not communicate with each other, it is preferable that the water from the makeup water container be branched and supplied.

In this case, the first heating part can be formed thinner than the second heating part, and the first heating part can be connected from the bottom surface of the second heating part by a communication pipe. In this case, the first and second heating parts can be connected. Even though each heating unit is a separate body, water is supplied from the makeup water container through the communication pipe to generate steam early from the first heating unit as in the above inventions, and then turn off the heater. It is possible to suppress power consumption and prevent scale from adhering in the first heating unit. Also,
By turning off the power supply to the second heating unit, it is possible to select the energy-saving use in which steam is generated only in the first heating unit.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a humidifier of the present invention will be specifically described based on the first to third embodiments with reference to the drawings.

(First Embodiment) A humidifier according to a first embodiment of the present invention shown in FIGS. 1 to 4 heats a supplied water 1 by a heater 2 while storing the supplied water 1, and steam generated thereby is steamed. Steam generation container 4 to be diffused to the outside through passage 3.
And a supply water container which is connected to the steam generation container 4 by a supply passage 5 and is mounted so that the water supply port 7 of the water supply tank 6 faces from above to a height substantially equal to the upper limit water level 8 of the steam generation container 4. 9 and 9.

The make-up water container 9 allows the water supplied from the water supply tank 6 to naturally flow into the steam generating container 4 through the make-up passage 5 until the water level becomes the same as that in the make-up water container 9. At this time, in the makeup water container 9, when the water in the water supply tank 6 flows into the height position where the water supply port 7 of the water supply tank 6 faces, the water supply tank 6
The inside of the water supply tank 6 is blocked from communicating with the outside and cannot be replenished with air, preventing further water 1 from flowing out, and when the water level falls below the water supply port 7, the outside air is supplied to the water supply tank 6. The water 1 is made to flow out while inhaling this.

In this way, in the steam generation container 4 supplied with water from the makeup water container 9, the received water 1 is heated by the heater 2
The steam is generated while always maintaining the upper limit water level 8 at the same height as the makeup water container 9 while heating and evaporating.

The make-up water container 9 and the steam generating container 4 are arranged in the body portion 10 of the body. A bottom member 11 integrally formed with legs 11a is fitted to a lower portion of the body portion 10, and a lid cover 12 is detachably fitted to an upper portion thereof.

The make-up water container 9 is integrally formed with the insole 13 which is integrally formed at the mid-height position of the body portion 10, while the steam generating container 4 is made of a heat-resistant metal member or the like. Opening 13 formed in the insole 13
It is applied from the lower side to the rim of a through the seal packing 14 and is attached at a plurality of points with screws 15.

The steam generating container 4 includes a first heating part 4a having a small capacity for rapidly raising the temperature of the water 1 to generate steam, and a steam having a capacity larger than that of the first heating part 4a and delayed from the first heating part 4a. And a second heating unit 4b that generates heat. In the first embodiment, the second heating part 4b is arranged in the central part of the steam generating container 4 to form a deep bottom, while the first heating part 4a is arranged in the annular part around the second heating part 4b. It is formed on the shallow bottom, and they are integrally formed to keep the same water level.
An annular heater 2a having a wattage suitable for a small amount of heating is attached to the bottom surface of the first heating portion 4a, and a cylindrical heater 2b is attached to the side circumferential surface of the second heating portion 4b. still,
It is desirable that the heaters 2 are separately attached to each other, which is suitable for the volume of water to be heated, but it is also possible to attach the heater 2 only to the first heating part 4a by utilizing the heat conduction of the metal container.

The first heating part 4a and the second heating part 4b maintain the same water level, and the boundary part is provided with a cylindrical wall-shaped partitioning part 16 having a height slightly lower than the water level. Conversely, as long as water is supplied from the water supply tank 6, the partition 1 is always
This means that the water level is kept slightly above 6. However, when the supply of the water 1 from the water supply tank 6 is stopped and the amount of the water 1 in the first heating unit 4a decreases, it is preferable to turn off the power supply by the thermostat. The first heating unit 4
Since a and the second heating part 4b are integrally formed and maintain the same water level, only one replenishment passage 5 is required, but the two may be formed separately with the positional relationship being the same, or higher than the water level 8. When the partition section 16 is provided, the branched supply path 5 is connected to each of the first heating section 4a and the second heating section 4b.

The convection of the water 1 in the first heating section 4a is suppressed by the partition section 16 in its annular portion, so that the high temperature water heated in the first heating section 4a moves to the second heating section 4b. And a small amount of water 1 in the first heating section 4a heated by the heater 2a is evaporated, so that a large amount of steam can be generated from the beginning of energization.

In the water supply tank 6, a water supply cap 6a for receiving the opening 6b is attached to a lower central opening 6b, and an opening / closing valve 17 which is biased in a valve closing direction is provided in the water supply cap 6a. On the other hand, the makeup water container 9 is provided with a projection 9a at a position corresponding to the opening / closing valve 17, and when the water supply tank 6 is set, the opening / closing valve 17 is pushed up by the projection 9a to be in an open state.

The steam passage 3 is fitted into a steam outlet tube 3a which is detachably supported by the upper end opening of the steam generating container 4 and an opening 12a formed in a part of the lid cover 12, so that the steam can be discharged. It is composed of a vapor discharge port member 3b having a vapor hole 19 that is dispersed and dispersed outside. A receiving portion 22 is formed at the upper opening of the vapor outlet tube 3a so as to receive the vapor discharge port member 3b. The receiving portion 22 has an aroma insert 1 at a position that does not interfere with the escape of vapor.
8 is integrally molded, and when the aroma stick 23 impregnated with the aroma solution is put therein, the vapor radiates around in the state containing the aroma component, so that a comfortable or medicinal atmosphere can be created. it can. Further, a dish-shaped aroma container 24 for containing the aroma liquid is attached to the mouth 22a of the receiving portion 22, and the aroma liquid is heated by the vapor emitted from the vapor generating container 4 to emit the aroma component. An atmosphere similar to that of the aromatic stick 23 can be created. Like this, Aroma Stick 2
Aromatherapy can be easily realized by selecting any one of the three or the aroma liquids of the aroma container 24 or mixing both.

FIG. 2 is a partial sectional view showing the vicinity of the float valve 25 and the electric equipment 26. As shown in the figure, the float valve 25 is supported by a pin 25a formed integrally with the makeup water container 9 so that a donut type float 25b can be raised and lowered according to the water level, and the float 25b is cooked in the steam generating container 4 in an empty state. Detecting this when descending to the idle cooking prevention position corresponding to the lower limit water level set to about immediately before, the electric equipment 26 stops the energization of the heater 2 or the like by an on or off operation or a signal based on this detection. It is designed to be safe to use.

(Second Embodiment) The second embodiment of the present invention shown in FIG.
The humidifier of the embodiment will be described. The overall configuration of the second embodiment is almost the same as that of the first embodiment except for the structure of the steam generating container 4, and the same parts are denoted by the same reference numerals.

In the humidifier, the supplied water 1 is stored and heated by a heater 2, and steam generated thereby is radiated to the outside through a steam passage 3.
And a supply water container which is connected to the steam generation container 4 by a supply passage 5 and is mounted so that the water supply port 7 of the water supply tank 6 faces from above to a height substantially equal to the upper limit water level 8 of the steam generation container 4. 9 and 9.

In the steam generating container 4 to which water is supplied from the makeup water container 9, the received water 1 is heated by the heater 2 to evaporate, and the upper limit water level 8 is the same as the height of the makeup water container 9 as that of the makeup water container 9. The steam is generated while always maintaining.

The makeup water container 9 and the steam generating container 4 are arranged in the body portion 10 of the container. A bottom member 11 integrally formed with legs 11a is fitted to a lower portion of the body portion 10, and a lid cover 12 is detachably fitted to an upper portion thereof.

The make-up water container 9 is integrally molded with the insole 13 which is integrally formed at the mid-height position of the body 10, whereas the steam generating container 4 is made of a metal member or the like having heat resistance. It is a molded product.

The steam generating container 4 includes a first heating portion 4a having a small capacity for rapidly heating the water 1 to generate steam, and a first heating portion 4a.
The second heating unit 4b has a larger capacity than the heating unit 4a and generates steam later than the first heating unit 4a. Second
In the embodiment, the first heating part 4a is arranged in the central part of the steam generating container 4 to form a shallow bottom, while the second heating part 4b is arranged in an annular part around the first heating part 4a to form a deep bottom. Formed into
They are formed integrally. The heating of the water 1 in the steam generating container 4 is performed by a disk-shaped heater (mica type, sheathed heater brazing type, etc.) attached to the bottom surface of the first heating part 4a.
2c only. By attaching this heater 2c to the shallow portion in the central portion of the steam generation container 4, the heating is conducted to the integrally formed second heating portion 4b and the central space inside the second heating portion 4b. By radiating the heat accumulated in, the water 1 of the second heating unit 4b can be efficiently heated by one heater. Moreover, even if the water supplied from the water supply tank 6 is exhausted and the water in the first heating section 4a is reduced, the water 1 remains in the second heating section 4b outside the first heating section 4a, so that it is possible to prevent empty cooking. A thermostat is attached to the second heating unit 4b to prevent the water 1 from being cooked in the second heating unit 4b by heating the heater 2c.

The first heating part 4a and the second heating part 4b maintain the same water level, and the boundary part is provided with a partition part 16 having a height slightly lower than the water level. The partition 16 is formed by press bending the bottom surface of the steam generating container 4. By forming the partition portion 16 by bending it, the first
Even if the heating portion 4a thermally expands due to the heating of the heater 2a, it can be absorbed by the peripheral wall 20 of the first heating portion 4a deforming outward. Instead of bending the partition 16 as described above, the partition 16 may be formed in a wall shape as in the first embodiment. Further, similarly to the first embodiment, the first heating part 4a and the second heating part 4b may be separately configured, and the branched supply passages 5 may be connected to the respective heating parts.

The convection of water 1 in the first heating section 4a is suppressed in the central portion by the partition section 16, so that the high temperature water heated in the first heating section 4a moves to the second heating section 4b. And a small amount of water 1 in the first heating section 4a heated by the heater 2a is evaporated, so that a large amount of steam can be generated from the beginning of energization.

In the water supply tank 6, a water supply cap 6a for receiving the opening 6b is attached to an opening 6b at the lower center, and an opening / closing valve 17 for urging in the valve closing direction is provided in the water supply cap 6a. On the other hand, the makeup water container 9 is provided with a projection 9a at a position corresponding to the opening / closing valve 17, and when the water supply tank 6 is set, the opening / closing valve 17 is pushed up by the projection 9a to be in an open state.

The steam passage 3 is fitted into a steam outlet tube 3a which is detachably supported by the upper end opening of the steam generating container 4 and an opening 12a formed in a part of the lid cover 12, so that the steam can be discharged. It is composed of a vapor discharge port member 3b which is dispersed and dispersed outside.

Since the humidifier of the second embodiment is constructed as described above, when the electric equipment 26 starts to energize the heater 2, first the heater 2c causes the first heating unit 4 to operate.
As in the case of the first embodiment shown in FIG. 4, the temperature of the water 1 in a rises, and the steam generation start time T ₁ becomes 5 minutes to 10 minutes earlier than in the case of the conventional pot-shaped steam generating container. . Also heater 2
The heat of c rapidly evaporates the water in the first heating unit 4a located in the central portion, and at the same time, the heat conduction to the annular second heating unit 4b and the second heating unit below the first heating unit 4a. The second heating portion 4b is also heated by the radiant heat trapped in the inner space of 4b to generate steam (steam generation start time T ₂ ). Then the second
The amount of steam in the heating unit 4b becomes larger than the amount generated in the first heating unit 4a, and the combined steam is diverged from the steam passage 3. As described above, also in the humidifier of the second embodiment, it is possible to satisfy the early humidification and the sufficient humidification while suppressing the generation of scale. In addition, even if the scale adheres to the first heating unit 4a and accumulates, since the adhered area is concentrated in the center and has a shallow bottom, it can be cleaned in a short time.

(Third Embodiment) A third embodiment of the present invention shown in FIG.
The humidifier of the embodiment will be described. The overall configuration of the third embodiment is substantially the same as that of the first and second embodiments, except for the structure of the steam generation container 4 and the structure of a part of the steam passage 3.
Similar parts are designated by the same reference numerals, and the description thereof will be simplified.

This humidifier is equipped with a steam generating container 4 and a makeup water container 9 similar to those in the first and second embodiments, and the steam generating container 4 supplied with water from the makeup water container 9 receives the same. While the water 1 is heated by the heater 2 and evaporated, steam is generated while always maintaining the upper limit water level 8 at the same height of the water supply port 7 as the makeup water container 9.

The make-up water container 9 is integrally formed with the insole 13 which is integrally formed at the mid-height position of the body portion 10, whereas the steam generating container 4 is made of a heat-resistant metal member or the like. It is a molded product.

In the third embodiment, the second heating part 4b, which generates steam later than the first heating part 4a, is used as the main body of the steam generation container 4 to which the supply passage 5 is connected, while the water 1 is rapidly supplied. The first heating unit 4a, which is heated to generate steam first,
It is a thin cylindrical portion connected from the bottom surface of the second heating portion 4b by a communication pipe 27. First heating unit 4a and second heating unit 4b
Although it is configured separately from, the water is communicated by the communication pipe 27 to maintain the same water level.

The water 1 in the steam generating container 4 is heated by a cylindrical heater 2d having a small wattage corresponding to a small amount of water attached to the side peripheral surface of the first heating portion 4a which is a part of the communication pipe 27.
And a cylindrical heater 2e attached to the side peripheral surface of the second heating unit 4b. The second heating portion 4b through the supply passage 5.
When the water 1 introduced from the first heating unit 4a to the first heating unit 4a is heated by the heater 2d and steam starts to be generated, the thermostat detects and turns off the power, and the heater 2d of the second heating unit 4b
It is preferable to heat only by itself. In this way, vapor is emitted from the first heating unit 4a only at the initial stage of energization, and then evaporation from the large-capacity second heating unit 4b is mainly performed, but it is introduced into the first heating unit 4a for energy saving use. It is also possible to configure to heat only the water 1 or to use the heaters 2d and 2e by turbo without turning off the energization of the heater 2d.

The steam passage 3 is fitted into a steam outlet tube 3a which is detachably supported by the upper end opening of the steam generating container 4 and an opening 12a formed in a part of the lid cover 12, so that the steam can be discharged. It is composed of a vapor discharge port member 3b which is dispersed and dispersed outside. Further, in the third embodiment, the upper portion of the communication pipe 27 above the first heating portion 4a functions as the vapor outlet portion 27a at the beginning of energization or at the time of energy-saving use. The steam emitted through the steam outlet 27a returns to the inside of the steam outlet cylinder 3a and is discharged to the outside from the steam outlet member 3b.

Since the humidifier of the third embodiment is constructed as described above, when the electric equipment 26 starts to energize the heater 2, both the heaters 2d and 2e cause the first heating section 4a and the second heating section 4a to operate. The water in the heating unit 4b is heated, but in the first heating unit 4a having a small capacity, as in the first and second embodiments, as shown in FIG. 4, steam is generated at a temperature immediately before the boiling point. start. The steam generation start time T _{1 at} this time is 5 to 10 minutes earlier than in the case of the conventional pot-shaped steam generating container. Then, with the passage of time, steam heated by the heater 2e of the second heating unit 4b having a large capacity is generated later than the first heating unit 4a (steam generation start time T ₂ ), and the amount thereof is larger than that of the first heating unit 4a. The amount is larger than the generated amount, and as a whole, it is possible to satisfy the early humidification and the sufficient humidification while suppressing the generation of scale as in the first and second embodiments.
It should be noted that the first heating is performed at the same time as the start of steam generation by the second heating unit 4b
If the power supply to the heater 2d of the heating unit 4a is turned off, only the steam from the second heating unit 4b is left. Further, in the third embodiment, since the heater 2d for the first heating section 4a is attached below the water level 8, excessive heating can be suppressed and the second
When steam starts to be generated from the heating unit 4b, the energization of the steam is turned off to prevent the scale from adhering.
In the humidifier of the third embodiment, the first heating part 4a and the second heating part 4b are formed separately, so that the heater 2 is attached only to the first heating part 4a as required for energy saving. You can also do it.

The present invention can be constructed in various modes other than that shown in the above embodiment. For example, the heater 2 evaporates the water 1 in the first heating section 4a constituting the steam generation container 4 first, and then the delay occurs. As long as it is attached so as to evaporate the water 1 of the second heating portion 4b, an electromagnetic induction type heater may be provided by separately providing a coil to generate heat.

[0047]

According to the main characteristics of the humidifier of the present invention,
The water from the water supply tank is replenished to the steam generation container through the makeup water container, and the capacity of the first heating unit is small when the heater is energized. Therefore, the small heating capacity suppresses the generation of scale due to excessive heating. Since the water temperature rises rapidly, it is possible to generate steam at an early stage. Due to the large capacity of the second heating part, a relatively large heating capacity suppresses excessive heating while slowly raising the temperature without generating scale. The temperature can be raised, and a large amount of steam can be generated, although later than the first heating unit. Therefore, early humidification and sufficient humidification can be satisfied while suppressing the generation of scale.

The first heating part and the second heating part are integrally formed so as to maintain the same water level, a partition part having a height slightly lower than the water level is provided at the boundary part, and a heater is provided at least in the first heating part. If provided, only one supply passage is required,
Water in the heating unit and the second heating unit communicate with each other, but convection of water in each unit can be suppressed in each heating unit by the partition unit.
Particularly, it prevents the high temperature water heated in the first heating section from migrating to the second heating section, and facilitates early evaporation of a small amount of water in the first heating section. When a heater is provided in the first heating unit, after evaporating the water in the first heating unit,
Water in the second heating part is delayed and evaporated by conducting heat to the steam generating container integrally formed with the first heat generating container.
When a heater is provided separately from the heating unit and the second heating unit,
When steam starts to be generated in the second heating unit, the power consumption of the heater of the first heating unit is turned off and power consumption can be suppressed accordingly, and scale adhesion to the inner surface of the first heating unit can be suppressed, which is preferable. Is.

The first heating portion and the second heating portion are placed in a positional relationship between the central portion and the annular portion around the central portion, and the first heating portion and the second heating portion have a first positional relation.
If the heating part is formed shallower than the second heating part, even if scales are attached, the adhesion area is limited to the first heating part with a shallow bottom, so it is easy to wash from above in a short time. You can

If the first heating portion is formed in the central portion in a shallow bottom, while the second heating portion is formed in a deep portion in the annular portion around it, the heater is attached to the central first heating portion. The heat of the heater quickly evaporates the water in the first heating portion located in the central portion, and at the same time, conducts heat to the annular second heating portion,
The radiant heat trapped in the space inside the second heating unit under the first heating unit can also heat the second heating unit to generate steam, and even one heater can efficiently generate steam.

The first heating part and the second heating part may be formed separately and each may be provided with a heater.
In the case of a structure in which water in the first and second heating sections does not communicate with each other, it is preferable that the water from the makeup water container be branched and supplied.

In this case, the first heating part can be formed to be thinner than the second heating part, and the first heating part can be connected from the bottom surface of the second heating part by a communicating pipe. In this case, the first and second heating parts can be connected. Even though each heating unit is a separate body, water is made to communicate from the makeup water container through the communication pipe, so that steam is generated early from the first heating unit as in the case of each of the above-described configurations, and then the heater is When turned off, the power consumption can be suppressed and the scale can be prevented from adhering to the inside of the first heating unit. Also, if the power supply to the second heating unit is turned off, the first
It is also possible to select energy-saving use in which steam is generated only in the heating section.
