Description

The present invention relates to a humidifier for supplying humidified air indoors.

Conventionally, in this type of humidifier, humidified air containing fine water droplets generated by a humidified air generating means installed in a water storage tank is blown into the room from a blower port. A convex portion is formed on the case-side flange surface that abuts on the flange surface, so that when the case is placed on the upper end of the water storage tank, the distance between the tank-side flange surface and the case-side flange surface is kept constant. Since the amount of air flowing into the water storage tank through the gap from the ventilation path around the water storage tank can be kept constant, water droplets adhere to the tank-side flange surface and the case-side flange surface. There is a device that can prevent the occurrence of contamination by scum and bleaching powder without installing a packing in the gap. (For example, Patent Document 1)

A heater control means 93 composed of a controlling SSR (Solid State Relay) is provided.

Next, the operation from start to finish of operation in this embodiment will be described with reference to the flow chart of FIG.

First, when the operation switch 81 of the operation unit 80 is operated, the control unit 90 opens the drain valve 71 to drain the water in the water storage tank 10, and when the water level sensor 12 detects an OFF signal, the water supply valve 61 is opened. The cleaning operation is performed by opening the water storage tank 10 and washing the inside of the water storage tank 10 with water. When the ON signal is detected in step S101, it is determined that a predetermined amount of water has been supplied into the water storage tank 10, and the water supply valve 61 is closed to perform a cleaning mode (step S101).

After the washing mode of step S101 is completed, the controller 90 turns on the heater 11 by the heater control means 93 until the temperature of the water detected by the water temperature sensor 13 becomes the same as the room temperature, and the mist motor 24 and the mist motor 24 are turned on. A start-up mode is performed in which a start-up operation controlled by the mist motor control means 91 and the blow fan control means 92 is performed so that the blower fan 51 reaches a predetermined rotational speed (step S102).

After the start-up mode of step S102 ends, the controller 90 causes the mist motor 24 and the blower fan 51 to rotate at a predetermined number of revolutions based on the humidification level and the air volume level set by the humidification switch 82 and the air volume switch 83. The rotation speed is controlled by the mist motor control means 91 and the blower fan control means 92 so as to be driven, and the ON/OFF state of the heater 11 is switched by the heater control means 93 to control the humidification level and the air volume level. A normal operation mode is performed in which a mist operation is performed to keep the combined temperature within a predetermined range (step S103).

Further, when the controller 90 judges that the water level in the water storage tank 10 becomes equal to or lower than the lower limit water level during the mist operation and the water level sensor 12 outputs an OFF signal, the water supply valve 61 is opened to flow water into the water storage tank 10 . When it is determined that the water level in the water storage tank 10 has reached the upper limit water level and the water level sensor 12 outputs an ON signal, the water supply valve 61 is closed to stop the water supply to the water storage tank 10. , it is possible to maintain the water level at which mist operation can be carried out at all times.

Further, when the controller 90 determines that it is time to perform the water replacement operation, the controller 90 stops the mist motor 24 and the blower fan 51, opens the drain valve 71 to drain the water in the water storage tank 10, and detects the water level sensor. If the water level sensor 12 detects the lower limit water level before the predetermined drain time for detecting the lower limit water level elapses, the drain valve 71 is closed and the water supply valve 61 is opened to supply water to the water storage tank 10. When the upper limit water level is detected by the water level sensor 12 or a predetermined water supply time elapses, the operation of closing the water supply valve 61 is repeated a predetermined number of times, and the mist motor 24 and the blower fan 51 are driven at a predetermined timing. By performing the operation, the inside of the water storage tank 10 is cleaned to prevent the occurrence of scale deposition.

Further, when the water level sensor 12 does not detect the lower water level within the predetermined drainage time during which the water level sensor 12 detects the lower water level during the water replacement operation, the control unit 90 determines that an error has occurred, and the mist motor 24 and the mist motor 24 By stopping the driving of the blower fan 51 and blinking the operation lamp 84, an error is notified, and by operating the operation switch 81, the operation is switched to an error state that prohibits the mist operation. When the control unit 90 determines that a predetermined error canceling operation such as operation of a specific switch (not shown) in the control unit 90 has been performed after the operator has performed maintenance, the error state is canceled and operation is performed. By operating the switch 81, the mist operation can be performed.

When it is determined that 16 hours have elapsed since the start of the normal operation mode in step S103, or that the operation switch 81 was operated during the normal operation mode and an instruction to end the mist operation was issued, the control unit 90 After stopping the motor 24, the drain valve 71 is opened to drain the water in the water storage tank 10, and after a predetermined time has passed, the water supply valve 61 is opened to wash the inside of the water storage tank 10, and then the drain valve 71 is closed. A cleaning operation is performed in which the valve is closed and a predetermined amount of water is stored in the water storage tank 10, and then a sterilization operation is performed for 10 minutes by turning on the heater 11 and heating the water to about 65° C. to sterilize the water. After 10 minutes have elapsed, the cooling operation is performed to cool the inside of the water storage tank 10, and when the temperature of the stored water drops below 60° C., the drain valve 71 is opened to perform a cleaning mode for draining water (step S104).

After the cleaning mode of step S104 is completed, the control unit 90 shifts to the drying mode (step S105), controls the blower fan 51 so that the blower fan 51 is driven at a predetermined rotation speed (for example, 800 rpm), and The drying operation is performed by continuously driving the blower fan 51 for a predetermined time (for example, 3 hours), and when it is determined that 3 hours have passed, the blower fan 51 is stopped to end the operation.

Next, the structure of the vicinity of the joint between the water storage tank 10 and the air/water separation case 30 will be described in detail.

Please refer to FIG. A tank-side flange surface 10 a extending horizontally outward of the water storage tank 10 is formed on the outer edge of the upper end of the water storage tank 10 . A gutter-like wind shielding member 16 is installed on the side wall of the water storage tank 10 and the partition plate 14 below the upper end of the water storage tank 10 .

Please refer to FIG. The windshield member 16 installed on the side wall of the water storage tank 10 has a horizontal portion 16a adjacent to the side wall of the water storage tank 10 and extending toward the inside of the water storage tank 10, and a horizontal portion extending toward the inside of the water storage tank 10. and a vertical portion 16b extending vertically upward from the other end of 16a.
Similarly, the windshield member 16 installed on the partition plate 14 has a horizontal portion 16a at one end adjacent to the partition plate 14 and extending leftward, and a vertical portion extending vertically upward from the other end of the horizontal portion 16a. 16b and .
In other words, the windshield member 16 is installed so as to narrow the air path of humidified air from the water storage tank 10 to the air-water separation case 30 surrounded by the side wall of the water storage tank 10 and the partition plate 14 .

As a result, when humidified air containing fine water droplets generated in the water storage tank 10 is blown from the water storage tank 10 toward the air-water separation case 30, the humidified air is blown to the upper end of the water storage tank 10 where the tank-side flange surface 10a is located. Since the humidified air can be shielded by the air shielding member 16, the humidified air can be prevented from reaching the tank-side flange surface 10a and the case-side flange surface 30a, and water droplets can be prevented from adhering.

Please refer to FIG. On the left side wall of the water storage tank 10, on the outer edge of the lower end of the steam separation case 30, there is a substantially L-shaped case-side flange surface that extends leftward substantially horizontally and then curves downward. 30a is formed. A hemispherical projection 30b is formed on a case-side flange surface 30a facing the tank-side flange surface 10a.

When the air-water separation case 30 is placed on the water storage tank 10, a predetermined gap is formed between the tank-side flange surface 10a and the case-side flange surface 30a due to the convex portion 30b of the case-side flange surface 30a. be. Therefore, the amount of air flowing into the water storage tank 10 from the outside of the water storage tank 10 through the gap can be kept constant, and the humidified air that tries to escape from the inside of the water storage tank 10 through the gap to the outside is pushed back. Therefore, water leakage can be prevented without inserting a packing or the like between the tank side flange surface 10a and the case side flange surface 30a, and the air/water separation case 30 can be easily attached and detached from the device main body 1. configuration can be achieved.

Please refer to FIG. The vertical portion 16 b of the windshield member 16 has its upper end located below the lower end of the air/water separation case 30 . Therefore, when attaching/detaching the air/water separation case 30, the air/water separation case 30 does not get caught on the vertical portion 16b, so that the attachment/detachment of the air/water separation case 30 can be performed smoothly. It is possible to prevent the lower end of 30 from being scratched.

See FIGS. On the horizontal portion 16a of the windshield member 16 located on the left side of the water storage tank 10, there is a generally crank-shaped horizontal plate with one end fixed to the horizontal portion 16a with a screw or the like and the other end in contact with the vertical portion 16b. A cover 16c composed of a member 16c1 and a rear member 16c2 connected to the rear end of the lateral member 16c1 and closing the rear side is installed. A drain hole 16d is formed through the horizontal portion 16a in a range covered by the cover 16c and the vertical portion 16b. The horizontal portion 16a of the windshield member 16 located on the left side of the water storage tank 10 is installed so that the rear side is lower than the front side.

As a result, the water droplets dripping from the side wall of the air-water separation case 30 are smoothly returned into the water storage tank 10 through the drain hole 16d. In addition, by shielding the humidified air rising from the water storage tank 10 through the drain hole 16d by the cover 16c, fine water droplets in the humidified air pass through the drain hole 16d, and the tank-side flange surface 10a and the case-side flange surface 10a are separated from each other. 30a can be prevented in advance.

The cover 16c has one surface facing the rotational direction of the rotating body 20 rotating clockwise and positioned in a direction perpendicular to the horizontal portion 16a. , and since it is installed so as to be closed by the back member 16c2, water droplets adhering to the horizontal portion 16a flow backward in accordance with the air flow direction accompanying the rotation of the rotating body 20 when the mist operation is performed. Water droplets adhering to the horizontal portion 16a can be efficiently collected in the drain hole 16d and returned to the water storage tank 10. - 特許庁

In addition, even if the fine water droplets generated in the water storage tank 10 pass through the drain hole 16d, the fine water droplets move along the rotation direction of the rotating body 20. Since a certain surface is closed by the cover 16c, the water droplets passing through the drain hole 16d are surely collected by the cover 16c, and fine water droplets are prevented from reaching the tank-side flange surface 10a and the case-side flange surface 30a. can do.

See FIG. The windshield member 16 on the right side of the water storage tank 10 has a drainage guide portion 16e extending vertically downward from the right end of the horizontal portion 16a so as to form a gap with the partition plate 14. As shown in FIG. The gap formed between the partition plate 14 and the drainage guide portion 16e is widened in the left-right direction so that the drainage guide portion 16e is located inside the water storage tank 10 from the lower end of the steam separation case 30 on the right side. is set.

As a result, water droplets adhering to the wall surface on the right side of the air-water separation case 30 during the mist operation and dropping upon reaching the lower end of the wall surface can be returned to the water storage tank 10 without remaining on the horizontal portion 16a.

See FIGS. Below the horizontal portion 16a of the windshield member 16, there is a support portion 16f composed of a portion connected to the side wall of the water storage tank 10 and a portion extending horizontally from the portion on which the horizontal portion 16a is placed. The support portions 16f are installed in front and rear of the water storage tank 10. As shown in FIG. By screwing the horizontal portion 16a to the support portion 16f, the horizontal portion 16a of the windshield member 16 can be fixed adjacent to the side wall of the water storage tank 10 and the partition plate 14. As shown in FIG.

Next, the effects of this embodiment will be described.

A gutter-like windshield member 16 is installed on the side wall of the water storage tank 10 positioned below the upper end of the water storage tank 10 . As a result, when the humidified air containing fine water droplets generated in the water storage tank 10 by the mist operation is blown toward the air-water separation case 30, the tank-side flange surface 10a at the upper end of the water storage tank 10 and the case-side flange face 10a are separated from each other. Even if fine water droplets in the humidified air are directed toward the surface 30a, the windshield member 16 can reliably prevent the humidified air from reaching the tank-side flange surface 10a and the case-side flange surface 30a. Fine water droplets inside adhere to the tank-side flange surface 10a and the case-side flange surface 30a, and the occurrence of stains due to water scale and bleaching powder can be prevented.

The shielding member 16 includes a horizontal portion 16a extending horizontally so that one end is adjacent to the side wall of the water storage tank 10 and the other end is positioned inside the water storage tank 10 from the lower end of the air/water separation case 30, and the horizontal portion and a vertical portion 16b extending vertically upward from the other end of 16a to a position below the lower end of the air-water separation case 30. Therefore, the humidified air containing fine water droplets generated in the water storage tank 10 is separated from air and water. When air is blown to the separation case 30, the humidified air can be reliably prevented from reaching the tank-side flange surface 10a and the case-side flange surface 30a by the air shielding member 16, so that the tank-side flange surface 10a and the case-side flange surface 30a It is possible to prevent the side flange surface 30a from being stained with water scale or bleaching powder due to water droplets adhering to the side flange surface 30a.

In addition, since the upper end of the vertical portion 16b is positioned below the lower end of the air-water separation case 30, when the air-water separation case 30 is attached or detached from the device body 1 for cleaning or maintenance work, the air-water separation case 30 is Since the lower end does not come into contact with the windshield member 16, the air/water separation case 30 can be smoothly attached/detached, and the vicinity of the lower end of the air/water separation case 30 can be prevented from being damaged during attachment/detachment.

In addition, the horizontal portion 16a of the windshield member 16 installed on the side wall of the water storage tank 10 on the left side is installed so as to block the surface other than the front direction, which is one surface positioned in the direction perpendicular to the horizontal portion 16a. A drainage hole 16d is formed through the horizontal portion 16a within the range of the cover 16c. Therefore, water droplets dripping from the side wall of the air-water separation case 30 onto the horizontal portion 16 are smoothly returned into the water storage tank 10 through the drainage holes 16d, and fine water droplets generated in the water storage tank 10 pass through the drainage holes 16d. Adhesion to the tank-side flange surface 10a and the case-side flange surface 30a can be reliably prevented.

In addition, the cover 16c is installed so as to open in the front direction, which is one surface facing the rotation direction of the rotating body 20 and positioned in a direction perpendicular to the horizontal portion 16a, and to close the other surface. Even if the humidified air generated in the water storage tank 10 passes through the drainage hole 16d, the humidified air that has passed through the drainage hole 16d in accordance with the rotation of the rotating body 20 advances in the rearward direction blocked by the rear surface member 16c2 of the cover 16c. Therefore, it is possible to reliably prevent the humidified air passing through the drain hole 16d from spreading above the horizontal portion 16a. can be prevented.

Further, on the right side of the water storage tank 10, a drainage guide portion 16e is formed which is located inward of the water storage tank 10 from the lower end of the water separation case 30 and faces the partition plate 14. Water droplets dripping from the drain are smoothly returned into the water storage tank 10 via the drainage guide portion 16e.

In this embodiment, the shielding member 16 is installed below the upper end of the water storage tank 10 to prevent water droplets from adhering to the tank-side flange surface 10a and the case-side flange surface 30a. Any content that can prevent water droplets from entering the gap in the air passage through which air passes is sufficient. It may prevent water droplets from adhering to the gap at the connection point with the blower port 50, and a trough-like shield is provided near the part where the gap exists in the middle of the air path through which the humidified air containing fine water droplets passes. As long as the content is such that the member 16 is installed, it falls within the scope of the present invention.
