Description

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

Conventionally, in this type of air, the dry air sucked from the intake port passes through the dry air passage and passes through the water storage tank installed on the downstream side of the dry air passage, so that the humidification installed in the water storage tank is performed. Moisture is contained in the dry air by the air generation means, and humidified air is generated. After the humidified air passes through the humidified air passage installed on the downstream side of the water storage tank, the humidified air is blown into the room from the air outlet to be blown into the room. In the case of humidification and air purification, a bypass opening is formed on the side of the humidified air passage so that the dry air passing through the dry air passage bypasses the water storage tank and can flow into the humidified air passage. There was something that increased the amount of humidified air blown to. (For example, Patent Document 1)

However, in this conventional case, the humidified air heated by the heater installed in the water storage tank and whose temperature has risen passes through the humidified air passage, so that when the dry air having a temperature lower than that of the humidified air flows in from the bypass opening. The vicinity of the bypass opening in the humidified air passage is cooled, and dew condensation water is generated.

Then, when the dew condensation water generated above the bypass opening in the humidified air passage drips from the upper end edge of the bypass opening, the dew condensation water is torn off by the dry air flowing into the humidified air passage through the bypass opening. When the dew water is carried to the air outlet, the area around the air outlet gets wet, and when the area around the air outlet dries after the operation is stopped, there is a problem that scale is deposited and the appearance is conspicuously dirty. As a result, there was a risk that the installation surface of the instrument body would get wet, so there was room for improvement.

In order to solve the above problems, in claim 1 of the present invention, a blower fan installed in the main body of the appliance and blowing dry air is used.
A dry air passage through which the dry air blown by the blower fan passes, and

It is characterized in that it is installed so that the angle formed by the surface and the guide surface is an acute angle.

According to the present invention, since a guide plate is installed so as to project inward along the upper end edge of the bypass opening toward the inside of the humidified air passage and to be inclined so that the other end side is downward from one end side in the width direction, the upper end of the bypass opening is provided. Since the dew condensation water that has reached the edge is guided to the other end side of the guide plate, the dew condensation water adhering to the upper end edge of the bypass opening is torn off by the dry air, guided to the air outlet, and scaled to the air outlet after the operation is stopped. It is possible to prevent problems caused by dew condensation, such as the adhesion of water and conspicuous stains on the exterior, and the possibility that the installation surface of the instrument body may get wet due to the dew water that has ejected from the air outlet.

Further, the guide plate has a protruding portion extending in the width direction on the other end side, and a slit is formed between the protruding portion and the side surface of the air / water separation case.

The water level sensor 13 that detects the water level by moving the float up and down, and the heating heater 11 and the power supply that are installed on the outer wall of the water storage tank 10 and continue to heat without switching to the OFF state and become abnormally high temperature. A manual return type bimetal thermostat 14 that opens the contacts and does not automatically return the contacts, and each heater 11 is arranged between the upper heating heater 11a and the rotating body 20 and when there is no water in the water storage tank 10. It is provided with a heat shield plate 15 that protects the rotating body 20 from radiant heat radiated by continuing in the ON state.

Is installed.

See FIG. Reference numeral 24 denotes a mist motor 24 which is installed above the water storage tank 10 and constitutes a humidified air generating means for rotationally driving the rotating body 20 by supporting the drive shaft 21. When the mist motor 24 is driven, the humidified air is generated. The rotating body 20 constituting the means rotates to draw water from the inner wall of the water storage tank 10 and scatters in the outer peripheral direction from a plurality of scattering ports (not shown) formed at the upper end of the rotating body 20 to form the humidified air generating means. By colliding with the porous portion 23, the water becomes finer and a large amount of mist having a diameter of nanometer (nm) is generated, and at the same time, large water droplets having a relatively large diameter are generated.

If the water level in the water storage tank 10 is lower than the lower limit water level, it becomes difficult for the rotating body 20 to pump up 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.

A heater control means 93 composed of an SSR (solid state relay) for controlling the above is provided.

(Explanation of driving operation)
Next, the operation from the start to the end of the operation in this 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 13 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 to supply the water level sensor 13. When the ON signal is detected, a cleaning mode is performed in which the water supply valve 61 is closed on the assumption that a predetermined amount of water has been supplied into the water storage tank 10 (step S101).

When the cleaning mode of step S101 is completed, the control unit 90 turns on each heater 11 by the heater control means 93 until the water storage temperature detected by the water storage temperature sensor 12 becomes the same value as room temperature, and the mist motor 24 And the start-up mode for executing the 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 is performed (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 each heater 11 is switched and controlled by the heater control means 93 to control the humidification level and the air volume level. A normal operation mode for executing a mist operation within a predetermined temperature range according to the above is performed (step S103).

When the blower fan 51 is driven at a predetermined rotation speed during the normal operation mode, the dry air in the room is sucked from the intake port 50 formed on the bottom surface of the instrument main body 1 and passes through the blower path 54, and then the dry air. A part of the air flows into the water storage tank 10 through the water storage tank inflow port 10a, becomes humidified air containing mist, rises in the air-water separation case 30, and other dry air is air-water from the bypass opening 32. The humidified air containing mist is blown into the room with a large amount of air by flowing into the separation case 30 and merging with the humidified air rising from the water storage tank 10 to form mixed air and being blown into the room from the air outlet 40. can do.

When it is determined that the time elapsed from the start of the normal operation mode in step S103 is 16 hours, or 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 has ended. 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 each heating 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 and the operation is terminated.

(Explanation of bypass opening)
Next, the structure around the bypass opening 32 formed in the air-water separation case 30 of the present embodiment will be described.
See FIGS. 6 and 7. A bypass opening 32 is formed on the right side surface of the air-water separation case 30 on the downstream side of the baffle plate 31 at the uppermost stage. In the bypass opening 32, the lower end edge is parallel to the front-rear direction, the front end edge and the rear end edge are parallel to the vertical direction, and the upper end edge is inclined downward at a predetermined angle from the rear to the front. The bypass opening 32 is located at the uppermost stage of the air-water separation case 30 and is located within the range in the front-rear direction of the baffle plate 31 facing the bypass opening 32.

When the dry air flows into the air-water separation case 30 from the bypass opening 32, the flow of the humidified air rising in the air-water separation case 30 is disturbed in the vicinity of the bypass opening 32. Specifically, most of the humidified air that has passed through the baffle plate 31 at the uppermost stage of the air-water separation case 30 rises as it is, mixes with the dry air that has flowed in from the bypass opening 32, and becomes mixed air to form the air outlet 40. Is blown into the room. The other humidified air is directed toward the bypass opening 32, and is divided into above and below the bypass opening 32 by the dry air. The humidified air diverted upward of the bypass opening 32 merges with the mixed air toward the air outlet 40, and the humidified air diverted downward circumvents the bypass opening 32 and rises to merge with the mixed air.

The dew condensation water generated near the bypass opening 32 will be described in detail. When the mist operation is performed and each heating heater 11 in the water storage tank 10 is in the ON state, the humidified air whose temperature has risen to around 40 ° C. rises in the air-water separation case 30 due to the heating of the water. Inside the water separation case 30, the ambient temperature is around 40 ° C. and the relative humidity is considerably high. Since the temperature of the dry air flowing from the air passage 54 into the air-water separation case 30 through the bypass opening 32 is the same as room temperature, it is around 20 ° C. depending on the condition and time of the installed room. Therefore, the right side surface of the air-water separation case 30 near the bypass opening 32 is lower than the atmospheric temperature inside the air-water separation case 30 due to the dry air, so that the inside of the air-water separation case 30 above the bypass opening 32 Condensation water is generated on the right side of the.

(Explanation of guide plate)
See FIGS. 7, 8 and 9. At the upper end edge of the bypass opening 32, the front end 33b as the other end side is downward from the rear end 33a as one end side in the front-rear direction which is the width direction and protrudes to the left in the inner direction of the air-water separation case 30. A guide plate 33 is installed so as to be inclined so as to be. Then, in the present embodiment, the guide plate 33 is installed along the entire upper end edge of the bypass opening 32. By installing the guide plate 33, it is possible to prevent the dew condensation water generated on the right side surface inside the air-water separation case 30 from dripping from the upper end edge of the bypass opening 32.

See FIGS. 8 and 9. The guide plate 33 is formed so that a protruding portion 33c extending in the front direction in the width direction is formed at the front end 33b on the other end side, and the protruding portion 33c abuts on the front side plate of the brackish water separation case 30. A slit 33d is formed by cutting out between the protruding portion 33c and the right side surface of the air-water separation case 30. That is, the slit 33d is located on the front side of the front end edge of the bypass opening 32. Further, the slit 33d is formed so that the distance in the left-right direction between the right side surface of the air-water separation case 30 and the end surface of the protruding portion 33c facing the right side surface is less than 5 mm.

When the slit 33d is formed, the dew condensation water generated on the right side surface of the air-water separation case 30 located above the bypass opening 32 is guided to the front end 33b along the inclination of the guide plate 33, the slit 33d. It flows down along the right side surface of the air-water separation case 30 through the air-water separation case 30. The dew condensation water that has flowed down is dropped onto the water storage tank 10 along the right side surface of the steam separation case 30. Therefore, the dew condensation water generated above the bypass opening 32 can be efficiently collected in the water storage tank 10 by the slit 33d.

The width in the left-right direction between the right side surface of the air-water separation case 30 and the end surface of the protruding portion 33c facing the air-water separation case 30 is less than 5 mm. As the air volume increases, the dew condensation water collected in the slit 33d stays without falling toward the lower part of the air-water separation case 30, and the dew condensation water that has stayed is torn by the humidified air and guided to the air outlet 40. This is because the risk of condensation increases. That is, the air volume of the humidified air passing through the slit 33d depends on the drive level of the drive member on the upstream side of the slit 33d and the structure of the air passage, such as the rotation speed of the blow fan 51 and the air passage area of the air passage 54. When the mist operation is performed with the rotation speed of the blower fan 51 different from that of the present embodiment and the mist operation with a different blower path 54 structure, it is necessary to set the width of the slit 33d so that the dew condensation water does not tear off due to the humidified air. The width of 33d is not limited to 5 mm and can be changed as appropriate.

See FIG. The rear end 33a of the guide plate 33 is C-faced. As a result, the area of contact with the guide plate 33 of the humidified air rising from the water storage tank 10 is reduced, and the amount of water in the humidified air accumulated in the rear end 33a can be reduced, so that the water accumulated in the rear end 33a can be reduced. It is possible to prevent the humidified air rising in the air-water separation case 30 from being torn off and being guided to the air outlet 40.

See FIG. The guide plate 33 is formed in an inverted L shape by bending a sheet metal, and has a connection surface 33e connected to the right side surface on the outside of the steam separation case 30 by means such as welding, and the inside direction of the steam separation case 30. It is composed of a guide surface 33f protruding from the surface. Then, the angle θ formed by the connecting surface 33e and the guide surface 33f inside the air-water separation case 30 is formed to be an acute angle.

As a result, the dew condensation water that has flowed down to the guide plate 33 from above the bypass opening 32 is guided to the front end 33b where the slit 33d is located without flowing down from the left end side of the guide surface 33f, and thus collects on the left end side of the guide surface 33f. It is possible to prevent the dew condensation water from being torn off by the humidified air and being guided to the air outlet 40.

Next, the effect of the present invention will be described.

See FIGS. 6 and 7. At the upper end edge of the bypass opening 32, the front end 33b as the other end side is downward from the rear end 33a as one end side in the front-rear direction which is the width direction and protrudes to the left in the inner direction of the air-water separation case 30. A guide plate 33 is installed so as to be inclined so as to be. As a result, when the dew condensation water generated above the bypass opening 32 reaches the upper end edge of the bypass opening 32, the dew condensation water is guided to the front end 33b of the guide plate 33, so that the dew condensation drips from the upper end edge of the bypass opening 32. It is possible to prevent water from being torn off by the dry air flowing into the air-water separation case 30 from the bypass opening 32, and the dew condensation water guided to the air outlet 40 causes scale to adhere to the air outlet 40. It is possible to prevent problems caused by the dew condensation water, such as the installation surface of the instrument main body 1 getting wet due to the dew condensation water blown out from the air outlet 40.

See FIGS. 8 and 9. The guide plate 33 has a protruding portion 33c extending in the front direction in the width direction formed at the front end 33b on the other end side, and a slit 33d is formed between the protruding portion 33c and the right side surface of the air / water separation case 30. As a result, the dew condensation water flowing to the front side of the guide plate 33 travels along the right side surface of the air-water separation case 30 through the slit 33d and flows down to the water storage tank 10, so that the dew condensation water accumulated above the bypass opening 32 is discharged. It is smoothly guided to the water storage tank 10 without continuing to accumulate on the guide plate 33.

See FIG. It is formed so that the angle formed by the connecting surface 33e and the guide surface 33f constituting the guide plate 33 is an acute angle. As a result, the dew condensation water collected on the guide plate 33 is guided to the slit 33d without dripping from the end surface of the guide surface 33f which is the inner direction of the air-water separation case 30, and therefore the dew condensation water dripping from the end surface of the guide surface 33f. Is guided to the air outlet 40 by the dry air flowing into the air-water separation case 30 from the bypass opening 32, and the scale adheres to the air outlet 40, and the dew condensation water blown out from the air outlet 40 installs the instrument body 1. It is possible to prevent problems caused by dew condensation, such as the surface getting wet.

In the present embodiment, the entire upper end edge of the bypass opening 32 is covered with the guide plate 33, but since it is sufficient that the dew condensation water does not drip at the upper end edge of the bypass opening 32, for example, the place where the dew condensation water is generated may be. If only the front side of the bypass opening 32 in the front-rear direction is used, only the front side of the bypass opening 32 in the front-rear direction may be covered with the guide plate 33, and the entire upper end edge of the bypass opening 32 may be covered with the guide plate 33. The invention is not limited to covering with.

Further, in the present embodiment, as a means for generating humidified air, the water in the water storage tank 10 is heated by each heating heater 11, and the water in the water storage tank 10 is pumped up by the rotating body 20 by driving the mist motor 24 to the surroundings. Although it has been described that fine mist is generated by scattering and colliding with the porous portion 23, steam-type humidified air generation is performed by heating the water in the water storage tank 10 to a high temperature by a heating means such as a heater to generate humidified air. It may be a means, and any means for generating humidified air that causes a difference in temperature between the humidified air and the dry air can be applied because the action and effect according to the present invention are generated, and the range is equal to that of the present invention.
