Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifying structure and control method for a humidifier such as a vaporization type which mainly prevents a room from drying in a general household.

[0002]

2. Description of the Related Art A conventional vaporization-type humidifier absorbs water by a vaporization filter and vaporizes the water by blowing air to the vaporization filter for humidification. The first problem is to obtain a large amount of humidification. Was that. There are four main methods of increasing the amount of humidification.

The first method of increasing the amount of humidification is to blow warm air to the vaporization filter 3, as shown in FIG. In the figure, water is supplied from the water supply unit 4 to the water tank unit 2, the vaporization filter 3 absorbs the water, and the air blown from the air blower 5 is heated by the warm air heater 9 provided in the air passage 8. It becomes hot air and is blown onto the vaporization filter 3.

The amount of water vaporized from the vaporization filter 3 is increased as compared with the case of normal temperature air because the air blown is warm air. As an example of this method, JP-A-6-6643 is used.
There is No. 7 publication.

The second method of increasing the amount of humidification is to cause hot water to be absorbed by the vaporization filter 3, as shown in FIG. In the figure, the water supplied from the water supply unit 4 to the water tank unit 2 is heated by the heater 6 for hot water to make hot water, and air is blown from the blower 5 to the vaporization filter 3 that has absorbed the hot water.

The amount of water vaporized from the vaporization filter 3 is increased as compared with the case of water at room temperature because the water supplied is hot water.
As an example of this method, there is JP-A-2000-356373.

The third method of increasing the amount of humidification is to increase the surface area of the vaporization filter 3 to promote the vaporization of water.

The fourth method of increasing the amount of humidification is to accelerate the speed of air blown by the air blower 5 to promote vaporization of water.

The second problem is that in FIG. 6 and the like, miscellaneous bacteria and the like that have propagated in the water of the water supply section 4 and the like are not scattered in the air. When the water remaining in the water supply unit 4 becomes old and various bacteria propagate, when the vaporization filter 3 absorbs this water and vaporizes it, there is a problem that a bad odor is generated or various bacteria are scattered into the air in the room. .

As a method for solving this problem, there is a method in which the vaporization filter 3 is impregnated with hot water and the temperature of the water is maintained for a predetermined time to remove bacteria. As an example of this method, Japanese Patent Laid-Open No.
There is a publication of 01-193972.

[0011]

As described above, in the humidifier in which the warm air is blown to the vaporization filter 3 to increase the humidification amount, if the humidification amount is desired to be further increased, the output of the warm air heater 9 is changed. Although it is possible to increase the temperature, if the output of the heater 9 for warm air is increased, the temperature of each part such as the air passage 8 rises. Therefore, it is necessary to use parts with high heat resistance, and the number of these parts is large. It will increase the cost.

Further, in a humidifier in which hot water is absorbed by the vaporization filter 3 to increase the amount of humidification, if the amount of humidification is desired to be further increased, it is possible to increase the output of the heater for hot water 6, but the heater for hot water is If the output of 6 is increased, the water in the water tank portion 2 boils, which may cause burns, which poses a safety problem.

Further, in the humidifier in which the surface area of the vaporization filter 3 is increased to increase the amount of humidification, if it is desired to further increase the amount of humidification, it is possible by increasing the surface area of the vaporization filter 3. In order to increase the surface area, the volume of the vaporization filter 3 must be increased, and the size of the product must be increased and the compactness must be sacrificed. In many homes, space-saving products are preferred, and large products are shunned, which reduces the commercial value.

Further, in the humidifier in which the air velocity of the air blower 5 is increased to increase the amount of humidification, if the amount of humidification is desired to be further increased, it is possible to increase the output of the air blower 5, but noise is generated. It will increase and will have to sacrifice quietness. Since such a humidifier is frequently used even during sleep, a product with a large noise is shunned by the user, and the commercial value is reduced.

Further, a conventional humidifier in which the vaporization filter 3 is impregnated with warm water and the temperature of the water is maintained for a predetermined time to sterilize and prevent miscellaneous bacteria propagated in the vaporizing water from being scattered into the air is as follows. It included two problems.

The first problem is that when the blower 5 and the heater 6 for warm water for heating water are controlled, they are turned on at the same time, so that vaporization is started before the water temperature rises and the sterilization is performed. Therefore, the eradication was incomplete.

The second problem is that the water supply section 4 becomes empty,
When the water level in the water tank unit 2 drops below a certain level, for example by stopping the water supply, the operation is forcibly stopped by the information from the water level sensor 16 that detects the water level. However, in this state, water may remain in the water tank portion 2 or the vaporization filter 3 may contain water, and over time, germs and the like may propagate, which may cause offensive odors and propagated germs. There was a problem that they would be scattered in the air of the room.

The present invention is intended to solve the above problems, and it is an object of the present invention to increase the amount of humidification while maintaining the compactness and quietness of the product without increasing the cost significantly and without impairing the safety. And

Another object of the present invention is to reliably prevent the germs and the like from scattering into the air in the room even if the germs and the like propagate in the water remaining in the water supply section.

[0020]

In order to solve the above-mentioned problems, the present invention provides a water tank portion for storing water inside a main body,
A vaporization filter that absorbs and vaporizes water in the water tank, a water supply unit that supplies water to the water tank, a blower that blows air to the vaporization filter, and an air blower that blows air from the suction port to the blower outlet. In a humidifier having an air passage configured by a distribution path, a heater for warm air is provided in the air passage between the air blower and the vaporization filter, and hot water for heating water in the water tank is provided near the water tank. It is equipped with a heater, an operation unit that sets the operating mode, humidity, etc. on the side or top of the main unit, and a humidity sensor and a control unit that detect the humidity of the room inside the main unit, and the control unit is the humidity detected by the humidity sensor. The output of the blower, the heater for hot water, the heater for warm air, and the like is controlled according to the setting information of the control unit and the operation unit.

[0021]

When the FF or the light is turned on or off, the state is continued unless otherwise specified. Further, FIG. 4 shows an example of three types of initial processing.

First, the case where the initial processing is shown in FIG. 4A will be described.

When the user operates the keys of the operation unit 12 to set the humidity and the operation mode and start the operation, initial processing is performed.

In the case of the initial processing shown in FIG. 4A, the control unit 10
Is a built-in timer 11 which starts measuring time from the start of operation, turns off the blower 5 and turns on the heater 6 for hot water.
N, the heater 9 for warm air is turned off to heat the water in the water tank portion 2, and an initial process is performed to display on the display portion 13 that the water is being heated. In practice, the water in the water tank portion 2 is heated to sterilize the water in the water tank portion 2, and the sterilization lamp of the display unit 13 is turned on.

The control unit 10 terminates the initial process and shifts to the humidifying process after a lapse of a certain time from the start of operation by the timer 11. That is, the control unit 10
Judges that heating of water is completed, that is, sterilization is completed,
The display indicating that the water is being heated (specifically, the sterilization lamp) is turned off. This method can eliminate bacteria at low cost because the water temperature sensor 15 can be eliminated.

When the initial process is completed, the humidifying process shown in FIG. 3 is subsequently executed.

In this humidifying process, the control unit 10 turns on the blower unit 5, turns on the humidifying lamp, and the operating unit 12
The humidity detected by the humidity sensor 14 is set to a low value on the basis of the humidity set according to the set humidity or the operating mode.
Judgment is made in three levels, medium and high.

When the humidity detected by the humidity sensor 14 is low ("low" in FIG. 3), the control unit 10 determines that the maximum amount of humidification is required, and the air blower 5, the hot water heater 6 and the hot air are used. All of the heaters 9 are turned on, hot air is blown to the vaporization filter 3 to promote vaporization, and the water in the water tank portion 2 is heated to further promote vaporization.

When the humidity detected by the humidity sensor 14 is medium ("medium" in FIG. 3), the control unit 10 determines that medium humidification is necessary, and turns on the blower 5 and the hot water heater 6. Then, the heater 9 for warm air is turned off, and air at room temperature is blown to the vaporization filter 3 to heat the water in the water tank portion 2 to promote vaporization.

When the humidity detected by the humidity sensor 14 is high ("high" in FIG. 3), the control unit 10 determines that a small amount of humidification is necessary, turns on the air blower 5, and turns on the heater 6 for hot water. The wind heater 9 is turned off, and air at room temperature is blown to the vaporization filter 3 to vaporize water at room temperature.

While the water in the water supply section 4 is present, more specifically, while the water level in the water tank section 2 detected by the water level sensor 16 exceeds a predetermined threshold value, the above humidification process is repeated.

When the water supply section 4 runs out of water, more specifically, when the water level in the water tank section 2 detected by the water level sensor 16 falls below a predetermined threshold value, the filter drying process described below is started.

When the water level in the water tank section 2 detected by the water level sensor 16 falls below a predetermined threshold value, the control section 10 starts measuring the time from the start of the filter drying process with the built-in timer 11 for hot water. The heater 6 is turned off, the heater 9 for warm air is turned on, and a filter drying process is performed to display on the display unit 13 that the vaporization filter 3 is being dried. In practice, the control unit 10 heats the air to be blown to dry the vaporization filter 3, turn on the filter drying lamp of the display unit 13 and turn off the humidifying lamp.

The control unit 10 terminates the filter drying process when the measured time from the start of the filter drying process by the timer 11 has passed a certain time. That is, the control unit 10
Judges that the vaporization filter 3 has been dried, turns off the air blower 5, turns off the warm air heater 9, and turns off the filter drying lamp.

When the filter drying process is completed, the control unit 1
0 turns on the water supply lamp and stops the operation. Energize the user to supply water by turning on the water supply lamp. When the user supplies water, the control unit 10 turns off the water supply lamp.

Next, the case where the initial process is shown in FIG. 4B will be described.

In the case of the initial processing shown in FIG. 4B, the control unit 10
Detects the water temperature of the water tank portion 2 with the water temperature sensor 15, and when the detected water temperature is below the threshold value, the blower device 5 is turned off, the hot water heater 6 is turned on, and the warm air heater 9 is turned off. Is heated, and an initial process for displaying on the display unit 13 that water is being heated is executed. Actually, the water in the water tank 2 is heated to sterilize the water in the water tank 2, and the sterilization lamp of the display unit 13 is turned on.

When the water temperature detected by the water temperature sensor 15 exceeds the threshold value, the control section 10 terminates the initial processing and shifts to the humidification processing. That is, the control unit 10 determines that the heating of the water is completed, that is, the sterilization is completed, and turns off the display (specifically, the sterilization lamp) indicating that the water is being heated. According to this method, the temperature of water that can be sterilized is grasped and the treatment is performed, so that the sterilization can be reliably performed.

Since the operation after the humidifying process is the same as that in the case of FIG. 4A, its explanation is omitted.

Further, the case where the initial processing is shown in FIG. 4C will be described.

In the case of the initial processing shown in FIG. 4C, the control unit 1
Reference numeral 0 denotes a built-in timer 11, which starts measuring time from the start of operation, detects the water temperature of the water tank portion 2 by the water temperature sensor 15 in parallel, turns off the air blower 5, and turns on the heater 6 for hot water.
N, the heater 9 for warm air is turned off to heat the water in the water tank portion 2, and an initial process is performed to display on the display portion 13 that the water is being heated. In practice, the water in the water tank portion 2 is heated to sterilize the water in the water tank portion 2, and the sterilization lamp of the display unit 13 is turned on.

When the time measured by the timer 11 from the start of operation exceeds a certain time, or when the water temperature detected by the water temperature sensor 15 exceeds the threshold value, the control unit 10
The initial process is completed and the process proceeds to the humidification process. That is, the control unit 10 determines that the heating of the water is completed, that is, the sterilization is completed, and turns off the display (specifically, the sterilization lamp) indicating that the water is being heated. This method is a method for surely and safely removing bacteria because the temperature of water that can be removed is grasped and the heating time of water is limited.

Since the operation after the humidifying process is the same as that in the case of FIG. 4A, the description thereof will be omitted.
