Description

  The present invention relates to an ion generator with a humidifier having both a function of releasing moisture to humidify and a function of generating ions.

  Conventionally, ion generators have become the mainstream as a virus removal measure due to the growing health orientation. In addition, it is a well-known fact that optimization of environmental humidity by a humidifier or the like is effective as an effect of suppressing virus activation.

  Humidifiers and ion generators are well-known electrical devices, but at present, each is provided to the market as a separate product, and users who want to receive humidification and ion supply at the same time. The fact is that each device is purchased separately and used at the same time. However, even if the humidifier and the ion generator are purchased separately, it is necessary to have a space corresponding to each of the two devices in the room, and it is necessary to secure respective power sources for both devices, and the direction of moisture supply And the ion emission direction must be individually adjusted for each device, and the installation and use remains complicated.

  Also, when a humidifier and ion generator are used together in the same room, the moisture and ions released from each are supplied in different directions that are not related to each other. You cannot benefit from both features at the same time.

  If both effects are expected here, install an ion generator and a humidifier configured separately in the same room, or use an ion generation device (here, a plasma cluster ion generator) in the humidification function side air path. A certain degree of synergistic effect is expected. However, there is dissatisfaction that the amount of ions generated cannot be expected due to the change in the air volume (wind speed) on the humidification side due to appropriate humidification.

  Operation control of the humidification function repeats operation and its stop according to the humidity in the room even if the operation is turned on. That is, when humidification up to a predetermined humidity is achieved in the room, normally the humidity is maintained for a while, so the humidification function is controlled such as reducing or stopping the humidification function. When the humidity changes sufficiently from the predetermined humidity, the deviation from the target humidity increases, and the humidifier is operated again. Therefore, when the humidification function is lowered or stopped, the operation of the blower fan is controlled to be lowered, and the intake of air from the air intake port of the humidification function is weakened or temporarily stopped.

  In contrast, the ion generator does not have a long enough life until the humidity changes, so the ion generator always keeps a continuous air flow during operation, and the required amount of ions Must be released continuously. Therefore, the ion generator and the humidifier are incompatible with each other because the required items such as the air volume and the time required for the air volume are different in the air volume control, and the ion generator is not compatible with the outlet of the humidifier. Such a requirement that it is installed in an air channel cannot meet these requirements.

If the air intake port for humidification and the air intake port for generating ions are arranged adjacent to each other, interference will occur in the air intake state at each air intake port. There is a concern that will not be secured.
In addition, when the functions of both an ion generator and a humidifier are incorporated, there are problems to be solved in terms of installation space and price.
Furthermore, the conventional ion generator is formed with one air path. And the ion generator provided in the air path is provided so that attachment or detachment is possible. The above-described system formed by a single air passage requires a large-diameter fan and is a wide product.

  9 and 10 are a front sectional view and a side sectional view showing an example of a conventional humidifier. In the humidifier 50, air is taken in from the air intake 52 on the front surface of the casing 51 by the fan motor 60 and the fan 61 driven thereby. The taken-in air passes through a humidifying filter 56 placed on a tray 55 that receives water supply from the tank 54 after the dust is removed by the dust removing filter 53, and receives supply of water vaporized at that time. The humidified air is discharged from the outlet 58 through the blower duct 57. An ion generator 62 is provided in the vicinity of the humidifying filter 56, and is devised so that the ions generated by the ion generator 62 are included in the humidified air and discharged.

  The present applicant prevents ions from being attenuated by the distance from the air outlet of the air conditioner to the seat and the length of the duct, and easily diffuses ions around the seat with high concentration preferentially at low cost. The ion generator which can do is provided (refer patent document 1). The ion generator includes a blower and an ion generator that generates positive ions and negative ions, and the ion generator is attached to a seat disposed in a space in a building or a space in a moving body, or It is installed near the seat.

  By the way, humidity is related to the amount of ion generation, and it is known that the ion generation efficiency decreases when the humidity is lower than the optimum humidity (30% or more). As described above, the operation contents required for the humidification function and the ion generation function are different, and it is required that there is a certain amount of humidity when ions are generated.

Therefore, the humidity required for ion generation using humidified air obtained by the humidifying function in the ion generator with the humidifying function in which the air blowing fan and the air path are separately provided for the humidifying function and the ion generating function, respectively. There is a problem to be solved in terms of ensuring.
An object of the present invention is to solve the above-mentioned problem, and in an ion generator with a humidifying function having both ion generation and humidification functions, the humidity around the ion generator is low so that the efficiency of ion generation is low. In the case of humidity, use humidified air obtained by the humidification function to secure the humidity around the ion generator, maintain high ion generation efficiency, and perform control corresponding to the functional purpose to achieve a health-oriented living environment Is to propose.

  In order to achieve the above object, an ion generator with a humidifying function according to the present invention includes a humidifying side air passage that humidifies and blows off air sucked into the air blowing passage by the air blowing fan, and another air blowing fan. The humidification function is provided independently with an ion generation side air passage for adding ions by passing the air sucked into the air passage different from the air passage through the front of the ion generator arranged in the air passage. In the attached ion generator, a humidity sensor that detects the humidity of the air introduced into the ion generation side air passage is installed, and the humidity detected by the humidity sensor is lower than the optimum humidity for generating ions. The damper which partitions an air path and the said ion generation side air path is opened, and a part of humidification air which flows through the said humidification side air path is made to flow into the said ion generation side air path.

  According to the ion generator with a humidifying function according to the present invention, the humidity sensor detects the humidity of the air introduced into the ion generation side air passage, and when the humidity detected by the humidity sensor is lower than the optimum humidity for ion generation, Accordingly, the damper that separates the humidification side air passage and the ion generation side air passage is opened, and a part of the humidified air flowing through the humidification side air passage flows into the ion generation side air passage. Using the humidified air, the humidity in the ion side air passage can be raised to the optimum humidity for generating ions.

  Moreover, in this ion generator with a humidification function, when there is not enough space in the vicinity of the ion generator to install a humidity sensor, the humidity sensor can be installed at the outlet of the ion generation side air passage. . When the humidity of the introduced air is detected at the outlet of the ion generation side air passage, and the detected humidity falls below the optimum humidity for ion generation, control is performed to open a damper that partitions the humidification side air passage and the ion generation side air passage.

  Moreover, in this ion generator with a humidification function, when there is not enough space to install a humidity sensor inside the device, the humidity sensor can be installed outside the ion generator with a humidification function. When the humidity of the room air is detected by a humidity sensor outside the ion generator with a humidifying function, and the detected humidity is lower than the optimum humidity for generating ions, a damper for partitioning the humidification side air path and the ion generation side air path is opened.

  Furthermore, in this ion generator with a humidifying function, the humidifying side air passage and the ion generating side air passage are partitioned by using a common casing as a partition, and a part of the partition can be swung to the humidifying side air passage to provide a damper. Can do.

  Since the ion generator with a humidifying function according to the present invention is configured as described above, the air path necessary for the ion generating function and the humidifying function is made independent, and the air path has an effective position, structure, and function. Thus, each function can be sufficiently exhibited, and an inexpensive and space-saving product can be provided. Moreover, according to this ion generator with a humidification function, since the ion generation and the humidification function are provided in the same housing, the two functions can be moved together when carrying, and the air path can be separately provided. Since they are equipped with each other, they can be operated individually without interfering with each other, and the indoor environment can be arranged in a health-oriented manner. And according to this ion generator with a humidification function, when the humidity in the ion side air passage detected by the humidity sensor falls below the optimum humidity, the humidification side air passage and the ion generation side air passage are accordingly changed. The humidifier air that has been humidified by the humidification function is mixed with the air introduced into the ion generation side air passage. The humidity in the ion side air passage is raised to the optimum humidity for ion generation, and high ion generation efficiency can be maintained.

The ions generated by the ion generator 24 are supplied into the room from the outlet 14 by the flow of air (indicated by arrows) flowing through the ion blowing duct 23.

  Details of the humidifying function unit 11 are shown in the left side of FIGS. 5 and 6 and FIG. 7. FIG. 7 is a longitudinal sectional view showing the humidifying function side of the ion generator with a humidifying function shown in FIGS. 1 and 2. As shown in FIG. 5 to FIG. 7, the humidifying function unit 11 includes a casing 1 facing the humidifying casing A <b> 26 and an outer humidifying casing A <b> 26 in which an opening connected to the air intake port 13 is formed. 1 and a humidifying casing B27 disposed on the inner center side. A space 37 is formed between the upper portions of both the humidifying casings 26 and the left side surface 6 of the casing 1, and the humidifying casing is located in the space 37 at a position where the humidifying air blowing motor 30 faces the air intake port 13. It arrange | positions in the aspect supported by A26. Between the humidification casings 26 and 27, a blower duct 33 is formed as a humidification side air passage extending upward toward the blowout port 15. An output rotation shaft 30a of the humidification blower motor 30 passes through the humidification casing A26 and protrudes into the blower duct 33. A humidification blower fan 31 is attached to the output rotation shaft 30a. Rotates the humidifying fan 31 in the air duct 33. A suction guard 28 is stretched in the air intake port 13 of the housing 1 in order to prevent a human hand, a finger, or a foreign object from entering a dangerous state.

  A humidifying water tray 34 is disposed in the lower space 32 of the humidifying casing A 26, and humidifying water is supplied from the humidifying water tank 35 to the humidifying water tray 34. The humidifying water tray 34 is provided with a humidifying filter 36, and the humidified water sucked up by the humidifying filter 36 is the lower space 32 in which the air sucked from the air intake port 13 by the humidifying air blowing motor 30 -the humidifying air blowing fan 31. When the air passes through the humidifying filter 36, it becomes moisture and is contained in the air. The air thus humidified passes through the blower duct 33 and is discharged from the outlet 15 into the room or the like. The flow of inhaled air and humidified air is indicated by arrows.

  In order to provide the humidifying water tray 34 and the humidifying filter 36, the humidifying function unit 11 is configured wider than the ion generating unit 10. Therefore, the humidifying casing B27 is provided at a position closer to the ion generation unit 10 side than the center of the left and right sides of the casing 1, and as a result, the air duct 33 moves the central portion of the casing 1 from the vicinity of the bottom of the casing 1. It extends to the vicinity of the top surface 7 of the housing 1. Since the blowout port 15 is formed in the left half of the top surface 7 of the housing 1, the airflow sucked into the blower duct 33 by the humidifying blower fan 31 is sent to the left side and then directed to the blowout port 15. The humidifying air blowing motor 30 is set to rotate clockwise as viewed from the air intake port 13 side in order to efficiently blow air according to the arrangement of the air blowing duct 27.

The space can be effectively used and the product can be made compact. The ion casing B17 that is a part of the air passage wall of the ion air duct 23 and the humidification casing B27 that is a part of the air passage wall of the air duct 33 constitute a single partition wall 40.

The control function of the ion generator with a humidifying function controls the damper 41 to open in response to the humidity of the air detected by the humidity sensor 42 being lower than the optimum humidity (30% or more) for ion generation. When the indoor air humidity becomes high by the humidification function of the ion generator with the humidification function until the optimum humidity is ensured, the damper 41 is controlled to close in response to the humidity sensor 42 detecting the humidity. The humidity sensor 42 can be installed on the outside of the ion generator 1 with a humidifying function (on the outer surface of the housing 2) instead of the outlet 14 of the ion blowing duct 23, and the damper 41 of the ion blowing duct 23 is also provided. It can also be provided at an appropriate position upstream.

  FIG. 6 shows a state in which the damper 41 is opened, and a portion of the humidified air flowing through the air duct 33 flows into the ion air duct 23 through the open damper 41. The airflow flowing into the ion blowing duct 23 is shown as Fc. Since the humidified air flows into the ion blowing duct 23 at the upstream side of the ion generator 24, the ion generator 24 is mixed with the air flow sent by the ion blowing motor 20 around the ion generator 24. Therefore, the ambient humidity is kept below the optimum humidity, and the ion generation efficiency can be kept high.

  FIG. 8 is a diagram showing ion generators with a humidifying function according to the present invention arranged side by side on the right ion generating unit 10 side and the humidifying function unit 11 side. The damper 41 provided in the partition wall 40 that partitions the humidification side air passage and the ion generation side air passage is closed. The flow of the air taken in by the ion generation part 10 side and the humidification function part 11 side is shown by the arrow. According to the ion generator with the humidification function, the necessary air paths are independent in the ion generation unit 10 and the humidification function unit 11, respectively, and an air volume (wind speed) necessary for ion generation is ensured on the ion generation air path side. An ion blowing motor 20 and an ion blowing fan 21 driven by the motor 20 are provided to perform optimal control for the generation of ions, and a humidifying air blowing motor 30 for securing appropriate humidity on the humidifying function side, and A humidifying air blower fan 31 driven by the motor 30 is provided, and independent motor operation control is performed on the ion generation side air passage and the humidifying function side, so that each function can be sufficiently exhibited. It has become. Since the structure of each part 10 and 11 is as having shown the detail in FIGS. 4-7, description for the second time is abbreviate | omitted.

  FIG. 9 schematically shows the state of the air flow blown out from the ion generator 1 with a humidifying function according to the present invention. In the drawing, the air flow 38 blown out from the ion generation unit 10 and the air flow 39 blown out from the humidification function unit 11 toward the rear of the ion generator 1 with the humidification function are drawn separately. Of course, it may be configured to blow out toward the front of the functioning ion generator 1 or so that both airflows are mixed. In this case, it is possible for both airflows to form a single flow and reach the humid air and ions farther. It is obvious that the blowing direction may be changed by the louver 19.

  In the illustrated example, the ion generator 10 provided with the ion generator is provided as one ion generator. However, instead of such a structure, two fans are provided, and the ion generator is provided on the outlet side of each fan. Two ion generators may be provided, and each ion generator may be operated according to the operation of the corresponding blower. In this case, a humidifier constituted by a water supply device and a humidification filter can be arranged for one air passage. In addition, the electrode for ion generation can be arrange | positioned on a different surface.
