Description

The present invention relates to a humidifying device that supplies humidified air into a room.

Conventionally, in this type of humidifying device, the humidifying air containing water droplets generated by a rotating body installed in the water storage tank is driven by a blower fan to blow air into the room from the air outlet. A case having an air inlet formed through it was placed, and a convex portion was formed on the case-side flange surface formed at the lower end of the case so as to abut against the tank-side flange surface formed at the upper end of the water storage tank. Therefore, when the case is placed on the upper end of the water storage tank, the distance between the gap formed between the tank-side flange surface and the case-side flange surface can be kept constant, and the air passage around the water storage tank can be maintained through the gap. Since the amount of air flowing into the water storage tank can be kept constant, water droplets may adhere to the flange surface on the tank side and the flange surface on the case side, causing stains due to water stains and scallops. There was something that could be stopped before it was installed. (For example, Patent Document 1)

JP-A-2019-32122

However, in this conventional one, there is no configuration capable of preventing the water droplets generated around the rotating body from reaching the air inlet, so that the water droplets scattered around the rotating body can be prevented from reaching the air inlet. There was room for improvement because it easily reached the vicinity and water droplets adhered to the flange surface on the tank side, causing stains due to water stains and scallops.

An object of the present invention is to provide a humidifying device capable of reliably preventing water droplets scattered around a rotating body from easily reaching an air inlet.

According to the present invention, there is a side collecting portion between the rotating body and the side wall of the water storage tank, which collects water droplets scattered from the rotating body toward the side of the water storage tank, and the rotating body and the water storage tank. An upper collecting part located between the upper end and collecting water droplets scattered from the rotating body toward the upper part of the water storage tank,
Since the partition member composed of is installed between the air inlet and the rotating body, even if the water droplets scattered from the rotating body are directed toward the air inlet, the side collecting part and the upper collecting part in the water storage tank are collected. Since the water droplets are surely collected by the part, it is possible to prevent the water droplets from easily reaching the air inlet.

Further, the side collecting portion closes a predetermined range between the rotating body and the side wall of the water storage tank facing the entire side surface of the rotating body on the water of the water storage tank, and opens another range.

Next, the mist generator according to the embodiment of the present invention will be described with reference to the drawings.
See FIG. 1 is an instrument main body, 2 is an upper surface panel constituting the front upper part of the instrument main body 1, 3 is a lower surface panel forming the front lower part of the instrument main body 1, and 4 is a breaker cover for hiding a breaker (not shown).

See FIG. Reference numeral 10 denotes a water storage tank which is located at a substantially middle height position in the instrument main body 1 and stores a predetermined amount of water. Inside the water storage tank 10, a heating heater 11 that is installed below the water surface and heats the stored water by switching between an ON state and an OFF state, a water level sensor 12 that detects the water level by moving the float up and down, and vertically above. It is composed of a case support plate 14a whose upper end extending in the direction abuts on the lower end of the air-water separation case 30 to support it, and a motor mounting plate 14b on which the support plate 14a is bent horizontally to mount the mist motor 24. A support member 14 and a support member 14 are installed. Further, an air inlet 15 through which dry air can flow in is formed on the upper right side of the water storage tank 10.

Further, on the outside of the water storage tank 10, a water storage temperature sensor 13 installed on the bottom surface of the water storage tank 10 and detecting the water storage temperature in the water storage tank 10 is installed.

See FIG. Reference numeral 20 denotes a cylindrical rotating body whose lower end is submerged in the water of the water storage tank 10 and is pivotally supported by the drive shaft 21 and has a hollow inverted conical shape whose circumference gradually expands upward. A cylindrical frame 22 that is located at a predetermined interval and rotates together with the rotating body 20, and a perforated portion 23 as a colliding body made of a large number of slits, wire mesh, punching metal, etc. on the entire peripheral wall of the frame 22. is set up.

See FIG. Reference numeral 24 denotes a mist motor 24 which is installed above the water storage tank 10 and rotationally drives the rotating body 20 by supporting the drive shaft 21. When the mist motor 24 is driven, the rotating body 20 rotates and the water storage tank 10 Water pumped from the inner wall scatters in the outer peripheral direction from a plurality of scattering ports (not shown) formed at the upper end of the rotating body 20 and collides with the porous portion 23, so that the water becomes finer and the particle size is nanometers (nm). A large amount of fine water droplets of a size are generated, and at the same time, large water droplets having a relatively large particle size are generated. Further, the rotating body 20, the perforated portion 23, and the mist motor 24 constitute a humidified air generating means.

The mist motor 24 uses a motor capable of rotationally driving the rotating body 20 only in the clockwise direction in a plan view. During the mist operation described later, the rotating body 20 is rotated clockwise according to each set state. Rotate by changing the number of rotations in the direction.

If the water level in the water storage tank 10 falls below the lower limit water level, it becomes difficult for the rotating body 20 to pump water, the amount of mist and negative ions generated decreases, and the amount of humidified air released into the room decreases. It will decrease.
Further, when the water level in the water storage tank 10 exceeds the upper limit water level, the load on the rotation of the rotating body 20 increases due to the viscous resistance of water, so that the mist motor 24 is loaded and the product life is shortened.
From the above, by keeping the water level in the water storage tank 10 within the range from the lower limit water level to the upper limit water level, it is possible to secure the amount of water pumped by the rotating body 20 and prevent the load increase of the mist motor 24.

See FIG. Reference numeral 30 denotes a brackish water separation case located above the water storage tank 10 that connects the water storage tank 10 and the air outlet 40, and allows humidified air containing mist generated in the water storage tank 10 to pass through. A plurality of plate-shaped baffle plates arranged in the middle of 30 so as to be staggered.

When the humidified air passes through the air-water separation case 30, large water droplets having a large particle size contained in the humidified air adhere to the baffle plate 31, and when the large water droplets adhering to the baffle plate 31 accumulate, the side surface of the air-water separation case 30 is pressed. It flows down and drops into the water storage tank 10. As a result, large water droplets are not guided to the air outlet 40, and the occurrence of dew condensation in the vicinity of the air outlet 40 can be prevented.

Further, the air-water separation case 30 can be pulled out toward the front of the instrument main body 1 by grasping a handle (not shown). As a result, the steam-water separation case 30 is periodically taken out from the instrument body 1 to perform maintenance, cleaning, and other work, and is returned to the original installation location after the work is completed. Trouble can be prevented before it happens.

See FIG. Reference numeral 40 denotes a blower port formed in a state where the front surface of the upper part of the instrument body 1 is open. The blower port 40 has a plate-shaped louver 41 capable of changing the wind direction in the vertical direction and humidified air blown into the room. It is equipped with a blower temperature sensor 42 that detects the temperature of the air, and humidified air containing mist that has passed through the air-water separation case 30 is blown into the room from the blower port 40 to perform indoor humidification and air cleaning. It becomes.

See FIG. Reference numeral 50 denotes an intake port formed on the bottom surface of the instrument main body 1 to allow indoor air to enter. In the intake port 50, dry air in the room is sucked by driving at a predetermined rotation speed toward the upper part of the instrument main body 1. A blower fan 51 that blows air to the air intake port 50, an intake air temperature sensor 52 that detects the atmospheric temperature of the dry air sucked into the intake port 50, and a humidity sensor 53 that detects the relative humidity in the room where the instrument body 1 is installed are provided. There is.

When the blower fan 51 is driven at a predetermined rotation speed, the dry air sucked from the intake port 50 formed on the bottom surface of the instrument body 1 is blown toward the upper part of the instrument body 1 to connect the intake port 5 and the water storage tank 10. The dry air passes through the air flow path 54, and the dry air that has flowed into the water storage tank 10 becomes humidified air containing mist, rises in the air-water separation case 30, and is blown into the room from the air outlet 40. Therefore, humidified air containing mist can be supplied to the room.

See FIG. Reference numeral 60 denotes a water supply pipe whose one end is connected to the side surface of the water storage tank 10 to supply city water into the water storage tank 10. In the middle of the piping of the water supply pipe 60, an electromagnetic valve is opened and closed to supply water into the water storage tank 10. A water supply valve 61 for controlling and a pressure reducing valve 62 for reducing the water supply pressure to a predetermined value are provided.

Reference numeral 70 denotes a drain pipe having one end connected to the lower part of the water storage tank 10 to drain the water in the water storage tank 10 to the outside of the instrument main body 1. In the middle of the piping of the drain pipe 70, an electromagnetic valve is opened and closed in the water storage tank 10. A drain valve 71 for controlling the drainage of water is provided.

See FIG. Reference numeral 80 denotes an operation unit provided on the upper surface panel 2 and provided with a plurality of switches and lamps. The operation unit 80 includes an operation switch 81 for instructing the start and stop of mist operation, and an ON / OFF state of the heater 11. The humidity detected by the humidity sensor 53 is preset to the three-stage humidification level that changes the amount of humidification that is the amount of water flowing out of the water storage tank 10 per predetermined time by changing the water storage temperature in the water storage tank 10 by switching. A humidification switch 82 that can be selected from the auto mode that changes the humidity level so that the humidity is adjusted, a three-stage air volume level that can set the magnitude of the rotation speed of the mist motor 24 and the blower fan 51, and a humidity sensor. An air volume switch 83 that can be selected from an ode mode that changes the air volume level so that the humidity set in 53 becomes a preset humidity is provided.

See FIG. A lamp corresponding to each switch is provided above each switch of the operation unit 80, and an operation lamp 84 that lights up when the operation switch 81 is operated and a lamp 84 that lights up when the mist operation continues for a predetermined time or longer during the disinfection operation. The disinfection lamp 85, the humidification level lamp 86 that displays the humidification level set by the humidification switch 82 with a numerical value of 1 to 3 and A indicating the auto mode, and the air volume level set by the air volume switch 83 from 1 to 3. And the air volume level lamp 87 displayed by A indicating the auto mode are provided.

See FIG. Reference numeral 90 denotes a control unit composed of a microcomputer that controls the operation content and valve opening / closing based on the detection value detected by each sensor and the setting content of each switch provided on the operation unit 80, and controls the mist motor 24. The mist motor control means 91 that drives at a predetermined rotation speed, the blower fan control means 92 that drives the blower fan 51 at a predetermined rotation speed, and the ON / OFF state of the heater 11 are switched to change the water temperature in the water storage tank 10. A heater control means 93 composed of an SSR (solid state relay) to be controlled is provided.

Next, the operation from the start to the end of the operation in this one embodiment will be described with reference to the flowchart 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 to flush the inside of the water storage tank 10 with water, and after a predetermined time elapses, the drain valve 71 is closed to supply the water flowing from the water supply valve 61 into the water storage tank 10 and the water level sensor 12 When the ON signal is detected in, a cleaning mode is performed in which the water supply valve 61 is closed assuming that a predetermined amount of water has been supplied into the water storage tank 10 (step S101).

When the cleaning mode in step S101 is completed, the control unit 90 turns on the heater 11 by the heater control means 93 until the water storage temperature detected by the water storage temperature sensor 13 becomes the same value as room temperature, and the mist motor 24 and A start-up mode is performed to execute a start-up operation controlled by the mist motor control means 91 and the blower fan control means 92 so that the blower fan 51 has a predetermined rotation speed (step S102).

When the start-up mode of step S102 is completed, the control unit 90 causes the mist motor 24 and the blower fan 51 to rotate at a predetermined rotation speed 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 and controlled by the heater control means 93 to obtain a humidification level and an air volume level. A normal operation mode for executing a mist operation within a predetermined temperature range is performed (step S103).

When the mist operation is carried out, fine water droplets generated by being pumped by the rotating body 20 and colliding with the porous portion 23 are scattered in the rotation direction of the rotating body 20. Since the scattered water droplets are affected by the rotation direction of the rotating body 20 and the wind direction of the dry air passing through the air inlet 15, it is significant toward the downstream side of the water storage tank 10 in which the air-water separation case 30 is installed. It does not flow to the air and moves in various directions.

Further, when the control unit 90 determines that the water level of the water storage tank 10 is equal to or lower than the lower limit water level and the water level sensor 12 outputs an OFF signal during the mist operation, the control unit 90 opens the water supply valve 61 and enters the water storage tank 10. When it is determined that the water level of the water storage tank 10 has reached the upper limit water level and the water level sensor 12 has output an ON signal, the water supply valve 61 is closed to stop the water supply into the water storage tank 10. , It is possible to maintain a water level at which mist operation can be carried out at all times.

Further, when the control unit 90 determines that the execution timing of the water replacement operation has been reached, the mist motor 24 and the blower fan 51 are stopped, the drain valve 71 is opened to drain the water in the water storage tank 10, and the water level sensor 12 detects the lower limit water level If the water level sensor 12 detects the lower limit water level by the time when a predetermined drainage time elapses, the drain valve 71 is closed and the water supply valve 61 is opened to supply water into the water storage tank 10. When the water level sensor 12 detects the upper limit water level or the predetermined water supply time elapses, the operation of closing the water supply valve 61 is repeated a predetermined number of times to replace the water that drives the mist motor 24 and the blower fan 51 at a predetermined timing. By carrying out the operation, the inside of the water storage tank 10 is cleaned to prevent scale precipitation from occurring.

Further, if the water level sensor 12 does not detect the lower limit water level within the predetermined drainage time during which the water level sensor 12 detects the lower limit water level during the water replacement operation, the control unit 90 determines that an error occurs and causes the mist motor 24. The drive with the blower fan 51 is stopped and the operation lamp 84 is blinked to notify the error, and the operation switch 81 is operated to switch to an error state prohibiting the execution of mist operation. Then, when the control unit 90 determines that a predetermined error release operation such as operation of a specific switch (not shown) in the control unit 90 has been executed after the maintenance by the operator has been performed, the error state is released and the operation is performed. By operating the switch 81, the mist operation can be performed.

When it is determined that the time elapsed from the start of the normal operation mode in step S103 is 16 hours, or that the operation switch 81 is operated during the normal operation mode and an instruction to end the mist operation is given, the control unit 90 determines that the mist operation is terminated. 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 clean the inside of the water storage tank 10 and then the drain valve 71 is opened. 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 in which the heater 11 is turned on and the water is heated to around 65 ° C. to sterilize the water. After 10 minutes have passed, a cooling operation for cooling the inside of the water storage tank 10 is executed, and when the water storage temperature becomes less than 60 ° C., a cleaning mode is performed in which the drain valve 71 is opened to drain water (step S104).

When the cleaning mode of step S104 is completed, the control unit 90 shifts to the drying mode (step S105), and the blower fan control means 92 controls the blower fan 51 to drive at a predetermined rotation speed (for example, 800 rpm). A drying operation is carried out in which the blower fan 51 is continuously driven 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 air passage structure from the air inlet 15 to the rotating body 20 in the water storage tank 10 will be described in detail.

See FIG. Reference numeral 16 denotes a partition member installed in the water storage tank 10. The partition member 16 includes a central shielding plate 16a located substantially in the center of the water storage tank 10 and attached below the motor mounting plate 14b, and an upper shielding plate 16b located on the right front side in the same plane as the central shielding plate 16a. , The side shielding plate 16c located on the side of the rotating body 20 and extending vertically downward from the right end of the central shielding plate 16a.
The central shielding plate 16a and the upper shielding plate 16b form an upper collecting portion, and the side shielding plate 16c constitutes a side collecting portion.

See FIGS. 7 and 8. The motor mounting plate 14b is installed so that the end surface in the front-rear direction is close to the side wall of the water storage tank 10.
Further, the central shielding plate 16a is installed between the right side of the motor mounting plate 14b and the right side wall of the water storage tank 10 so that the end surface in the front-rear direction is close to the side wall of the water storage tank 10.
Further, the upper shielding plate 16b is installed so as to be caught by a locking portion (not shown) on the right end edge of the central shielding plate 16a and the side wall of the water storage tank 10, and the front and right end faces are close to the side wall of the water storage tank 10. The rear end is located at the substantially center of the rotating body 20 in a plan view.
Further, the side shielding plate 16c is formed so that a member integrated with the central shielding plate 16a is bent vertically downward and inclined downward from the upper end to the lower end on the front end side, and the rear end surface is close to the side wall of the water storage tank 10. The lower end surface is below the water surface of the water storage tank 10, and the front end surface is installed so as to be located in front of the center of the rotating body 20 in a plan view.

Therefore, since the inside of the water storage tank 10 is partitioned by the partition member 16 into the lower part where the rotating body 20 is arranged and the upper part above the rotating body 20, fine water droplets scattered around the rotating body 20 are outside the water storage tank 10. Can be prevented from leaking to.

Further, since the partition member 16 can prevent the fine water droplets scattered from the rotating body 20 from reaching the mist motor 24, it is possible to prevent the occurrence of a problem due to the water droplets entering the mist motor 24.

See FIGS. 6, 7 and 8. An air inlet 15 is formed between the right side of the central shielding plate 16a and the rear of the upper shielding plate and the side wall of the water storage tank 10, and between the front of the side shielding plate 16c and the side wall of the water storage tank 10. The opening 17 is formed.

Therefore, the dry air that has passed through the ventilation path 54 passes through the air inlet 15 from the upper side to the lower side of the water storage tank 10, and then passes through the opening 17 by heading forward and then to the left. By bending the air passage a plurality of times from above the tank 10 until the dry air reaches the lower part of the water storage tank 10 where the rotating body 20 is arranged, fine water droplets scattered to the side of the rotating body 20 are discharged to the air inlet 15 It is possible to prevent the tank-side flange surface 10a at the upper end of the water storage tank 10 from becoming dirty.

See FIG. Since the rotating body 20 is rotationally driven only in the clockwise direction in a plan view, the water pumped by the rotating body 20 collides with the porous portion 23 and then scatters around in the rotating direction of the rotating body 20.
Therefore, the water droplets scattered from the rotating body 20 and heading upward in the water storage tank 10 collide with the motor mounting plate 14b and the central shielding plate 16a and fall downward, and are returned to the water in the water storage tank 10.
Further, the water droplets scattered from the rotating body 20 and heading to the right side of the water storage tank 10 collide with the side shielding plate 16c and fall downward and are returned to the water of the water storage tank 10.
Further, the water droplets that have passed through the opening 17 collide with the side wall of the water storage tank 10 located in front of the front end of the side shielding plate 16c, and the water droplets scattered above the opening 17 collide with the upper shielding plate 16b to store water. It is returned to the tank 10.

By installing the rotating body 10 below the water storage tank 10 partitioned by the support member 14 and the partition member 16 in this way, when the rotating body 10 is rotationally driven, the water droplets scattered above the rotating body 20 are generated. Water droplets collected by the motor mounting plate 14b, the central shielding plate 16a, and the upper shielding plate 16b and scattered to the right side of the rotating body 20 were collected by the side shielding plate 16c and thus scattered from the rotating body 20. The water droplets can be returned to the water of the water storage tank 10 without going from the air inlet 15 toward the upper end of the water storage tank 10, and the water droplets can be prevented from adhering to the tank side flange surface 10a.

See FIGS. 7 and 9. As the rotating body 20 rotates, the water droplets scattered around and attached to the side shielding plate 16c flow downward on the front side due to the influence of the wind direction and gravity generated by the rotation of the rotating body 20 and fall. Therefore, by setting the predetermined angle α formed by the front end and the lower end of the side shielding plate 16c at an acute angle, the water droplets reaching the front end can be smoothly guided to the water surface at the lower part of the water storage tank 10.
However, when the value of α becomes small, the area covered by the upper shielding plate 16b increases as the front upper end position of the side shielding plate 16c moves rearward, so that the opening area of the air inlet 15 decreases. As a result, the amount of air passing through the water storage tank 10 is reduced, and the amount of humidified air blown out from the air outlet 40 is reduced.
Therefore, the predetermined angle α is a value that makes it possible to secure the required amount of humidified air from the air outlet 40 while smoothly guiding the water droplets adhering to the side shielding plate 16c to the water surface under the water storage tank 10 (for example, α). = 80 °).

See FIGS. 8 and 9. In the partition member 16, the central shielding plate 16a and the side shielding plate 16c are integrally formed, and the upper shielding plate 16b is formed separately from the central shielding plate 16a and the side shielding plate 16c.
Further, the central shielding plate 16a is supported by fitting the front end surface 16a1 and the rear end surface 16a2 of the central shielding plate 16a into rails (not shown) located at the lower front end and the rear end of the motor mounting plate 14b and extending in the left-right direction. ing.
Further, the central shielding plate 16a is located so that the front end and the rear end are located outside the outer circumference of the perforated portion 23 that rotates integrally with the rotating body 20, and the left end is located to the left of the center of the rotating body 20. It is installed below the mounting plate 14b.

Therefore, when the partition member 16 is taken out from the water storage tank 10, the central shield plate 16a is pulled out to the right along a rail (not shown) of the motor mounting plate 14b after the upper shield plate 16b is removed. And the side shielding plate 16c can be easily pulled out from the water storage tank 10.
Further, since most of the space between the motor mounting plate 14b and the rotating body 20 is covered with the central shielding plate 16a, many water droplets scattered above the rotating body 20 adhere to the central shielding plate 16a. The amount of water droplets adhering to the motor mounting plate 14b, which cannot be easily removed from the water storage tank 10, can be minimized, and the central shielding plate 16a is periodically taken out from the water storage tank 10 for cleaning or parts replacement. As a result, it is possible to prevent a large amount of bleaching stains from remaining in the water storage tank 10.

Next, the effect of this embodiment will be described.

By installing a partition member 16 in the water storage tank 10 that faces the upper side and the side of the rotating body 20 and partitions the air inlet 15 and the rotating body 20, the rotating body 20 is rotationally driven by mist operation. At this time, the fine water droplets scattered around are collected by the motor mounting plate 14b, the central shielding plate 16a, the upper shielding plate 16b, and the side shielding plate 16c, so that the water droplets scattered around the rotating body 20 flow into the air. It is possible to prevent water droplets from easily reaching the inlet 15 and adhering to the tank-side flange surface 10a formed at the upper end of the water storage tank 10 to cause contamination.

Further, in the opening 17 formed between the side shielding plate 16c and the side wall of the water storage tank 10, the direction in which water droplets are scattered due to the rotation of the rotating body 20 and the flow direction of dry air passing through the opening 17 do not conflict with each other. Since it is formed at the location, it does not prevent dry air from flowing into the water storage tank 10 during mist operation, and further prevents fine water droplets scattered around the rotating body 20 from heading toward the air inlet 15. it can.

In the present embodiment, the central shielding plate 16a and the side shielding plate 16c constituting the partition member 16 are composed of an integral member, and the motor mounting plate 14b and the upper shielding plate 16b are composed of separate members. However, the present invention is not limited to this, and the motor mounting plate 14b and the central shielding plate 16a are integrated members, and the central shielding plate 16a and the side shielding plate 16c are composed of separate members. It is also preferable that the structure is such that water droplets scattered around the rotating body 20 and heading toward the air inlet 15 can be collected.

Further, in the present embodiment, the water in the water storage tank 10 is pumped up and scattered around, and the water droplets are generated by colliding with the porous portion 23 integrated with the rotating body 20, but the present invention is not limited to this. Even in the method of installing a wall surface so as to surround the circumference of the rotating body 20, the water pumped by the rotating body 20 is scattered toward the wall surface and collides with the wall surface to generate water droplets, the present embodiment will be described. Since the effect of the partition member 16 can be obtained, any water droplet generated by rotating the rotating body 20 falls within the scope of the present invention.
