Problems solved by technology

[0009] Also, although many home appliances are equipped with a microparticle diffusion device that diffuses microparticles into the air like the existing ion diffusion device 110a, there is the same problem as above that the diffusion ability of microparticles is low.

no. 1 Embodiment approach

[0101] The first embodiment will be described below. FIG. 1 is a schematic plan cross-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 fluid generating device 1a of the present embodiment includes a fluid supply device 2 for supplying a fluid such as gas or liquid, a fluid flow channel 3 for supplying the fluid sent from the fluid supply device 2, and a fluid flow channel 3 formed at the end of the fluid flow channel 3 to transfer the fluid. Air outlet 5 sent out in jet form, control part not shown. The fluid is transported by the driving of the fluid supply device 2 , flows through the fluid flow passage 3 , and is discharged from the blower outlet 5 as a jet flow to the outside. The arrows in the figure indicate the flow of the fluid.

[0102] In the fluid flow passage 3, the upstream portion of the blower outlet 5 is constituted by the enlarged pipe por...

no. 2 Embodiment approach

[0116] Next, a second embodiment will be described. Fig. 7 is a schematic plan sectional view showing the fluid generator of the present embodiment. Figure 8 It is a schematic side sectional view showing the fluid generator of this embodiment.

[0117] In this embodiment, instead of the guide plate 6 of the first embodiment, the fluid flow path 3 is divided into a plurality of enlarged pipe portions 3 b from the immediately downstream portion of the fluid supply device 2 . In the present embodiment, the fluid circulation channel 3 is divided into two in the left-right direction and two in the vertical direction, and is divided into four enlarged tube parts 3b in total, so four outlets 5 are provided. In addition, the aspect ratio of the fluid flow channel 3 and each enlarged pipe portion 3b divided by the division area increases as they approach the outlet 5, and the aspect ratio at the location of the outlet 5 is set to about 10. Other structures are the same as those of t...

no. 3 Embodiment approach

[0122] Next, a third embodiment will be described. Figure 10 It is a perspective view which shows the fluid generator of this embodiment.

[0123] In the fluid generator 1d of the present embodiment, the shape of the outlet 5 is height>width, as in another embodiment of the second embodiment. The fluid circulation channel 3 is divided into seven in the left-right direction and two in the up-down direction, and is divided into a total of 14 enlarged tube parts 3b, so that 14 outlets 5 are provided. And it is configured that the aspect ratio of the fluid flow channel 3 and each enlarged pipe portion 3b demarcated by the division increases as they approach the outlet 5, and the aspect ratio at the position of the outlet 5 (in this case, the height of the outlet / the width of the outlet) ) is set at around 8. Other structures are the same as in another embodiment of the second embodiment.

[0124] In this fluid generator 1d, the flow velocity distribution is different from the ...

Abstract

An object of the present invention is to provide a microparticle diffusing device capable of significantly extending the reach distance of microparticles emitted from the microparticle diffusing device, and capable of transporting the microparticles over a wide range, thereby improving the effect of the microparticles and reducing noise. Therefore, the microparticle diffusing device has a microparticle generating device that generates microparticles from a microparticle generating site, an air supply channel that transports the microparticles generated by the microparticle generating device, and a jet flow that is formed at the end of the air supply channel. Form the air outlet for emitting tiny particles, the aforementioned air supply channel, from the starting point toward the end point, the aspect ratio of the cross-section gradually increases.

Description

technical field [0001] The present invention relates to a microparticle diffusing device that emits microparticles over a wide area, and a refrigerator equipped with the same. Background technique [0002] As one of the fine particles emitted by the fine particle diffusing device, ions are mentioned. As one of the ions, there is H + (H 2 O) n and O 2 - (H 2 O) m ions, the so-called cluster ions. The ion diffusion device of Comparative Example 2 described later is provided with an ion generator 14 that generates the ions (refer to Figure 36 ). A refrigerator equipped with this ion diffusion device is described in Patent Document 1 and Patent Document 2 (refer to Figure 35 ). The refrigerator discharges ions to the outside of the refrigerator to sterilize the vicinity outside the refrigerator. Provides a hygienic living space by killing the airborne bacteria outside the refrigerator, and inhibits the intrusion of airborne bacteria from the outside to the inside of...
