Problems solved by technology

Therefore, since the ion concentration in the downstream area of ​​the lower part of the wind speed decreases, and the air flow with a higher wind speed does not flow through the discharge surface 14a of the ion generating device 14, the ion generation efficiency is also greatly reduced, and therefore, the diffusion ability of the ions is reduced.

no. 1 Embodiment approach

[0103] The first embodiment will be described. FIG. 1 is a schematic plan sectional view showing the fluid generator of the present embodiment, and FIG. 2 is a schematic side sectional view of the fluid generator of the present embodiment. The composition of the fluid generating device 1a of this embodiment includes: a fluid sending device 2, which sends out fluids such as gas or liquid; a fluid circulation channel 3, which transports the fluid sent from the fluid sending device 2; 3, and the fluid is sent out as a jet; and a control unit not shown. The fluid is conveyed by the driving of the fluid sending device 2 , flows through the fluid flow channel 3 , and is discharged to the outside as a jet from the outlet 5 . In addition, the arrows in the figure indicate the flow of fluid.

[0104] Furthermore, in the fluid flow passage 3, the enlarged pipe portion 3b constitutes an upstream portion of the outlet 5, and is configured such that the cross-sectional area smoothly expa...

no. 2 Embodiment approach

[0118] Next, a second embodiment will be described. Fig. 7 is a schematic plan sectional view showing the fluid generator of the present embodiment. Fig. 8 is a schematic side sectional view showing the fluid generator of the present embodiment.

[0119] In the present embodiment, the guide plate 6 of the first embodiment is not used, and the fluid flow path 3 is divided into a plurality of enlarged pipe portions 3b from the immediately downstream portion of the fluid sending device 2 . In the present embodiment, the fluid circulation channel 3 is divided into two left and right, and two vertically, and is divided into four enlarged pipe portions 3b in total, so four outlets 5 are provided. Furthermore, the divided and separated fluid circulation passage 3 and the respective enlarged pipe portions 3 b are configured such that the aspect ratio increases as they approach the outlet 5 , and the aspect ratio at the outlet 5 is set to about 10. Other configurations are the same a...

no. 3 Embodiment approach

[0124] Next, a third embodiment will be described. Figure 10 It is a perspective view which shows the fluid generator of this embodiment.

[0125] The fluid generator 1d of this embodiment is the same as the other embodiments of the second embodiment, and the shape of the outlet 5 is height>width. The fluid circulation channel 3 is divided into 7 parts left and right, and 2 parts up and down, and is divided into 14 enlarged pipe parts 3b in total, so 14 outlets 5 are provided. Furthermore, the divided and spaced fluid flow channels 3 and the respective enlarged pipe portions 3b are configured such that the aspect ratio becomes larger as they approach the outlet 5, and the aspect ratio of the position of the outlet 5 (in this case, outlet height / air outlet Exit Width) is set to around 8. Other configurations are the same as those of other embodiments related to the second embodiment.

[0126] In this fluid generating device 1d, the flow velocity distribution is different fr...

Abstract

An ion diffuser exhibiting a higher power by suppressing a disturbance or a drift flow occurring in the vicinity of an ion generator and enhancing ion generation efficiency and ion carrying efficiency. The ion diffuser comprises an ion generator generating ions from a discharge plane, an air supply passage for carrying ions generated by the ion generator, and an outlet formed at the end of the air supply passage for discharging ions. In the ion generator, an ion flow straightener is further provided in the air supply passage on the upstream side of the ion generator.

Description

technical field [0001] The present invention relates to an ion diffusion device that emits ions in a relatively wide range. Background technique [0002] Comparative Example 2 described later (refer to Figure 36 ) describes an example of a conventional ion diffusion device. A refrigerator equipped with this ion diffusion device 110a is described in Patent Document 1 and Patent Document 2 (refer to Figure 35 ). The refrigerator 200 emits ions outside the cabinet to kill bacteria near the outside of the refrigerator. Provides a hygienic living space by killing the planktonic bacteria outside the refrigerator, and suppresses the entry of planktonic bacteria from the outside of the refrigerator to the inside of the refrigerator when the door is opened and closed, to achieve a hygienic interior environment. [0003] exist Figure 37 In the figure, it is shown that in a room with a room temperature of 15° C., the H + (H 2 O) n and O 2 - (H 2 O) m The concentration of ...
