Description

The present invention relates to a mist generating device that supplies humidified air containing mist into a room.

Conventionally, in this type, the mist is generated by crushing the water in the water storage chamber by the mist generating means, and the mist operation is performed by blowing the humidified air containing the mist from the blower port to the outside of the instrument body by the blower fan. There is something to be done, by adjusting the humidification amount and the air volume according to the indoor humidity and the set mode, and changing the relative humidity of the room where the instrument body is placed so that the room can be maintained at the set humidity. Was there. (For example, Patent Document 1)

However, in this conventional type, if a muffle operation is performed by installing a muffle filter in the intake port that takes in air outside the instrument body in order to strengthen the muffle function, the muffle operation may cause ventilation resistance and reduce the amount of intake air. As a result, the air volume of the humidified air blown from the air outlet decreases, so it is not possible to blow the humidified air with a large air volume into the room in which the equipment body is installed, and the indoor air is extremely dry. In this case, even if the mist operation with the maximum air volume is carried out, there is a problem that it takes a long time until the indoor humidity reaches an appropriate value.

As a means to solve this, it is possible to replace the blower fan installed in the equipment body with one that can output a large amount of air, but since the blower fan becomes larger than before with the increase in output, The installation space of the fan increases and the volume of the equipment main body increases, which causes restrictions on the installation location of the equipment main body and increases the product cost, and when the blower fan is driven with a large air volume, it occurs inside the water storage chamber. Large water droplets with large particle size contained in the mist are not removed in the air-water separation air passage, and dew condensation water adheres to the members that make up the air outlet and drops from the instrument body, and the installation surface of the instrument body gets wet. Therefore, there was room for improvement.

In order to solve the above-mentioned problems, in claim 1 of the present invention, an instrument body, a blower fan installed in the instrument body for blowing air, and an air outside the instrument body formed in the vicinity of the blower fan are provided. A suction port for inhaling, an air purifying filter installed in the suction port for cleaning air that has passed therethrough, a ventilation path through which the air that has passed through the air cleaning filter that is formed in the instrument body flows, and the air in the ventilation path A water storage chamber having an inlet port for storing water, which stores water, a water storage chamber, a rotating body for pumping the water in the water storage chamber by rotation and scattering in the outer peripheral direction, and a shaft for rotating the rotating body. A mist motor connected to the supported drive shaft, a collision body that generates fine mist and large-sized water droplets by collision of water scattered by the rotating body, and a flow path vertically upward at the other end of the water storage chamber. Air-water separation air passage in which humidified air containing fine mist and large-sized water droplets generated in the water storage chamber is connected, and large-sized water droplets included in the humidified air installed in the air-water separation air passage are separated. Air-water separation means, and a blower port for blowing the humidified air containing a large amount of fine mist that has passed through the air-water separation air passage to the outside of the instrument body,
A bypass inlet through which air can flow into the air/water separation air passage from the air passage without passing through the water storage chamber is formed at least downstream of the air/water separation means in the air/water separation air passage. There is.

Further, in claim 2, a plurality of the air/water separating means are installed so that inclined surfaces inclined with respect to the opposing wall surfaces of the air/water separating air passage are staggered, and the bypass inlets are the blower outlets. It is characterized in that it is formed in the air/water separating air passage at a position facing the inclined surface of the air/water separating means installed at the closest position.

According to the present invention, the air blown by the blower fan passes through the water storage chamber and the air/water separation air passage so that the air volume does not decrease due to the pressure loss, so that the air/water separation air passage does not pass through the water storage chamber from the air passage. Since the bypass inlet that allows air to flow in is formed in the air-water separation air passage, even if a ventilation filter is installed at the inlet and ventilation resistance increases, the amount of air blown from the air outlet does not decrease. In addition, it is possible to eliminate a shortage of air volume during mist operation, and further, by forming a bypass inlet at least on the downstream side of the air/water separation means installed in the air/water separation air passage, the air/water separation means can humidify the air. Since the air that flows in from the bypass inlet merges with the humidified air after the large water droplets inside have been separated, the amount of large water droplets that reach the blower opening is reduced to prevent the installation surface of the instrument body from getting wet with dew condensation water. It can be prevented in advance.

In addition, a plurality of air/water separation means are installed so that the inclined surfaces inclined with respect to the opposing wall surfaces of the air/water separation air passage are staggered, and the bypass inlet is the air/water installed closest to the blower opening. Since it is formed in the air/water separation air passage at a position facing the inclined surface of the separation means, when the blower fan drives and the humidified air flows in the air/water separation air passage, the air placed near the water storage chamber Since a large number of large-sized water droplets in humidified air are separated by the water separation means, a bypass inlet is formed near the air inlet where the amount of large-sized water droplets is small. Since it is possible to significantly reduce the amount reaching up to, it is possible to prevent the lack of air volume during mist operation, and prevent condensation water from adhering to the vicinity of the blower opening and getting the installation surface of the instrument body wet.

When large-sized water droplets are collected, they flow under the influence of gravity along the inclined surface P to the lower end of the baffle plate 18 and fall into the water storage chamber 8.

Therefore, the amount of humidified air that has risen from the water storage chamber 8 is increased by the flow of air from the bypass inlet 51 into the air-water separation air passage 17, and the amount of humidified air that is blown into the room from the air outlet 2 is increased. The amount of air blow can be increased.

Next, the operation from the start to the end of operation in this embodiment will be described based on the flowchart of FIG.
First, when the operation switch 30 of the operation unit 6 is operated or when the operation start time set by the timer switch 33 is reached, the control unit 45 opens the drain valve 26 to drain the water in the water storage chamber 8. Then, when the OFF signal is detected by the water level sensor 21, the water supply valve 23 is opened to perform a cleaning operation of flushing the inside of the water storage chamber 8 with water, and after a predetermined time has passed, the drainage valve 26 is closed to flow from the water supply valve 23. Water is supplied into the water storage chamber 8, and when an ON signal is detected by the water level sensor 21, it is determined that a predetermined amount of water has been supplied into the water storage chamber 8 and the water supply mode is closed to close the water supply valve 23 (step S101). ).

When the water replacement mode of step S101 ends, the control unit 45 causes the heating heater control unit 48 to turn on the heating heater 19 until the stored water temperature detected by the stored water temperature sensor 20 becomes equal to room temperature, and the mist motor 11 is operated. And the start-up mode is executed to execute the start-up operation controlled by the mist motor control means 46 and the blower fan control means 47 so that the blower fan 14 has a predetermined rotation speed (step S102).

When the startup mode of step S102 is completed, the control unit 45 causes the mist motor 11 and the blower fan 14 to rotate at a predetermined rotation speed based on the humidification level and the air flow level set by the humidification switch 31 and the air flow switch 32. The mist motor control means 46 and the blower fan control means 47 control the number of revolutions so that the heaters 19 are driven, and the heating heater control means 48 switches the ON/OFF state of the heaters 19 to control them to obtain a humidification level and an air flow level. A normal operation mode is executed in which the mist operation is performed within the combined predetermined temperature range (step S103).

When it is determined that the operation switch 30 has been operated during the normal operation mode of step S103 and an instruction to end the operation has been given, the control unit 45 stops the mist motor 11 and then opens the drain valve 26 to open the water storage chamber 8. After draining the water and after a lapse of a predetermined time, the water supply valve 23 is opened to wash the inside of the water storage chamber 8 and then the drainage valve 26 is closed to perform a water exchange operation for storing a predetermined amount of water in the water storage chamber 8, and thereafter. The heater 19 is turned on to perform the sterilization operation for sterilization by heating the water for a predetermined time, and after that, the cooling operation for cooling the inside of the water storage chamber 8 is executed after the lapse of the predetermined time, and the stored water temperature is the predetermined temperature. When the following occurs, the drainage valve 26 is opened to perform the cleaning mode for draining (step S104).

When the cleaning mode in step S104 ends, the control unit 45 controls the blower fan control means 47 so that the blower fan 14 is driven at a predetermined rotation speed (for example, 800 rpm), and blows air to the water storage chamber 8 or the blower path 15. A drying mode for preventing the growth of bacteria by performing drying is performed (step S105), and it is determined whether or not the drive time of the blower fan 14 has counted a predetermined time (for example, 3 hours). To stop the operation.

Next, a detailed description will be given of the flow path of the humidified air during the mist operation and the influence of the air flowing in from the bypass inlet 51 on the flow path of the humidified air.
First, when the mist operation is started and the mist motor 11 and the blower fan 14 are driven at a predetermined rotation speed, the air in the room is sucked through the suction ports 49 on the bottom surface and the front surface of the instrument body 1 and passes through the air purifying filter 50. It becomes clean air from which dust in the air has been removed.
Then, the air that has passed through the air purifying filter 50 rises in the ventilation passage 15, is branched into the water storage chamber inlet 16 and the bypass inlet 51, and flows into the water storage chamber 8 and the air-water separation air passage 17 respectively.

The amount of each air flowing into the water storage chamber 8 and the air-water separation air passage 17 changes depending on the opening area of the water storage chamber inlet 16 and the bypass inlet 51, and the amount of air flowing in proportion to the increase of the opening area. Will also increase. Therefore, the amount of stored water is increased so that the amount of air blown into the room is moderately increased while ensuring a sufficient amount of air for guiding the humidified air containing fine mist and negative ions generated in the water storage chamber 8 to the blower port 2. The opening areas of the chamber inlet 16 and the bypass inlet 51 are designed.

The air flowing into the water storage chamber 8 from the water storage chamber inlet 16 is steamed as humidified air containing fine mist, large-sized water droplets and negative ions generated by being pumped up by the rotating body 10 and crushed by the porous portion 13. The separation air passage 17 is raised.
When the air-water separation air passage 17 is moved up, the flow paths meander by the baffle plates 18a, 18b, 18c, and flow so as to lick the inclined surface P of each baffle plate 18 so that large-sized water droplets in the humidified air are generated. When adhering to the surface of the baffle plate 18 and reaching the lower end of each inclined baffle plate 18, the water droplets drop into the water storage chamber 8 due to gravity, so that the amount of large-diameter water droplets carried to the air outlet 2 can be reduced. ..

Then, the humidified air that has risen in the air/water separation air passage 17 from the water storage chamber 8 and the air that has been split in the air passage 15 and that has flowed in from the bypass air passage 51 are connected to the downstream end of the air/water separation air passage 17. The humidified air mixed in the upper space 52 is guided in the blower port 2 direction by the guide plate 53 having a substantially L-shaped side view installed in the upper space 52, and the humidified air containing fine mist and negative ions is generated. Supplied indoors.

Thus, by forming the bypass air passage 51 into which the air flowing through the air blowing passage 15 can flow on the side surface of the air/water separation air passage 17, the water passes through the water storage chamber 8 and the air/water separation air passage 17, and is humidified by pressure loss. Even if the air volume of the air decreases, the air that is not affected by the pressure loss flows from the bypass air passage 51, mixes with the humidified air in the upper space 52, and is supplied from the blower port 2 to the room. Even if the ventilation resistance increases due to the attachment of the air purifying filter 50, the air volume of the humidified air supplied to the room does not decrease, and the humidification and air purifying can be effectively performed.

Further, since large-sized water droplets contained in the humidified air passing through the air/water separation air passage 17 during the mist operation have a larger mass than the fine mist, it is difficult to move up the air/water separation air passage 17 due to the influence of gravity. It is easy to adhere to the wall surface below the air/water separation air passage 17 near the water storage chamber 8 and the baffle plates 18b and 18c. Therefore, by forming the bypass inlet 51 at a position facing the inclined surface P of the baffle plate 18a located at the top of the air/water separation air passage 17 which is closest to the air outlet 2, large-diameter water droplets reach the air outlet 2. It is possible to prevent the guided amount from being reduced and the vicinity of the blower port 2 to be wetted by the dew condensation water so that the lower part of the instrument body 1 is wetted.

Furthermore, since the air-water separation air passage 17 is installed vertically upward, large-diameter water droplets adhering to the baffle plate 18 flow into the water storage chamber 8 when they fall from the end of the baffle plate 18, so that the device main body 1 It is possible to prevent water from leaking from the exterior of the device and prevent the installation surface of the instrument body 1 from getting wet.

As described above, since the bypass inlet 51 is formed on the side surface of the air/water separation air passage 17 that connects the water storage chamber 8 and the upper space 52, the air flowing through the air passage 15 by the air blowing fan 14 is generated during the mist operation. Humidified air that has split into the water storage chamber inlet 16 and the bypass inlet 51 and has passed through the water storage chamber 8 and the air/water separation air passage 17 and the air that has flowed in from the bypass inlet 51 are mixed in the upper space 52 to blow air. Since air is blown from the mouth 2 into the room, even if there is an increase in ventilation resistance due to the installation of the air-cleaning filter 50 at the suction port 49, or pressure loss caused by passing through the water storage chamber 8 and the air/water separation air passage 17. Since the air volume of the humidified air supplied from the blower port 2 to the room does not decrease, the indoor humidity is quickly improved and the air cleaning is effectively performed.

Further, since the bypass inlet 51 is formed on the side wall of the baffle plate 18a located at the uppermost stage of the air/water separation air passage 17 closest to the blower outlet 2 at a position facing the inclined surface P, the inflow from the bypass inlet 51 is made. The amount of large-sized water droplets floating in the air/water separation air passage 17 can be reduced by the generated air to be conveyed to the blower port 2. Therefore, condensed water adheres to the vicinity of the blower port 2 during mist operation, and It is possible to prevent the installation surface from getting wet.

In the present embodiment, the description has been given of the case where the bypass inlet 51 is formed on the side wall surface of the air/water separating air passage 17, but the present invention is not limited to this, and the upper portion is provided so that air can flow from the air blowing passage 15 into the upper space 52. A through hole is formed in an appropriate place on the lower surface of the space 52, and the air flowing through the air blowing path 15 during the mist operation is divided into the water storage chamber 8 and the upper space 52, and the humidified air that has passed through the air-water separation air passage 17 is formed. The air that has passed through the bypass inlet 51 may be mixed in the upper space 52 and blown from the blower port 2, that is, by passing through the water storage chamber 8 and the air/water separation air passage 17. As long as the composition mixes with the humidified air without being affected by the pressure loss and increases the amount of air blown from the blower port 2, the formation position of the flow passage that bypasses the water storage chamber 8 and the air-water separation air passage 17 is particularly designated. do not do.

Further, in the present embodiment, the baffle plate 18 is used as the air/water separating means, but the present invention is not limited to this, and fine water droplets are generated while separating large-diameter water droplets flowing in the air/water separation air passage 17. Any structure may be used as long as it can blow the humidified air containing air to the blower port 2. For example, fine water droplets can be generated by installing a plurality of mesh plates or plates having punch holes in the air/water separation air passage 17. Any configuration may be used as long as it is possible to separate large-sized water droplets while ensuring ventilation that allows the containing humidified air to flow.

Further, the other configurations used in the present embodiment are presented as examples, and are not intended to limit the scope of the invention, and can be implemented in various other modes. Various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and the gist of the invention, and are also included in the invention described in the claims and an equivalent range thereof.
