[0008] (Findings that formed the basis of this disclosure) At the time the inventors came up with the idea for this disclosure, there were sterilization devices available that could suction air containing droplets around a table, including near the edge of the table where a person is seated, and release sterilized air to sterilize the table. However, while conventional techniques are intended to sterilize harmful bacteria, there is a risk of bacteria resistant to the sterilization. In such cases, the inventors discovered a problem in that if a source of nutrition for harmful bacteria remains on the table, resistant harmful bacteria will grow, and in order to solve this problem, the subject matter of the present disclosure has been constituted. The inventors also discovered that when a nutrient source is present on the table, the proliferation of naturally occurring bacteria can be suppressed to an unnecessary extent by encouraging the proliferation of such bacteria. Therefore, the present disclosure provides a mist supplying device that can suppress the excessive proliferation of harmful bacteria by using naturally occurring bacteria.

[0009] Hereinafter, embodiments will be described in detail with reference to the drawings. However, unnecessary detailed description may be omitted. For example, detailed description of well-known matters or redundant description of substantially the same configuration may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0010] (Embodiment 1) Hereinafter, the first embodiment will be described with reference to the drawings.

[0011] [1-1.Configuration] Fig. 1 is a side cross-sectional view showing the mist supply device in embodiment 1. Fig. 2 is a front view showing the mist supply device in embodiment 1. Fig. 3 is a plan view showing the mist supply device in embodiment 1. 1 to 3, the mist supply device 1 is formed in the shape of a table. The mist supply device 1 includes two table tops 10 positioned approximately horizontally and legs 11 supporting each table top 10.

[0012] A mist generating system 20 is disposed between each table top 10. The mist generating system 20 has a main body 21 that is placed between each table top 10. The main body 21 extends along the longitudinal direction of the table top 10 and has approximately the same length as the table top 10. The main body 21 is formed in a box shape. A partition plate 22 is disposed in the approximate center of the main body 21 in the vertical direction. The upper surface of the partition plate 22 is an inclined surface 23 formed so that the height of one end is lower than the height of the other end. A drain outlet 24 is provided at the lowest portion of the inclined surface 23 of the partition plate 22. A drain receiver 25 is provided below the drain outlet 24. One end of a drain hose 26 is connected to the drain outlet 24, and the other end of the drain hose 26 is disposed inside the drain receiver 25.

[0013] A duct 30 serving as a mist supply section extending in the vertical direction is provided above the partition plate 22. The duct 30 extends along the longitudinal direction of the main body 21 and has a length dimension that is approximately the same as the length dimension of the main body 21. Above the partition plate 22 of the main body 21, on both sides of the duct 30, there are provided pot portions 31. The pot portions 31 contain soil 32 for growing plants and the like. Although not shown, the surface of the pot 31 facing the duct 30 is formed in a mesh shape. This allows the soil 32 in the pot 31 to be exposed to the duct 30.

[0014] At the upper end of the duct 30, a mist diffusion plate 33 is provided at a predetermined interval to cover the upper part of the duct 30. The mist diffusion plate 33 is formed in a roof shape with a high center and sloping downward toward each table top 10 side.

[0015] A space 40 is formed below the partition plate 22 of the main body 21. A mist generator 41 is housed inside the space 40. The mist generator 41 includes, for example, an ultrasonic mist generator 47 and a mist fan 48 for supplying the mist generated from the mist generator 47. Inside the mist generating device 41, a water level detecting device 49 for managing the water level stored inside the mist generating device 41 is provided. A communication pipe 42 that passes through the partition plate 22 and communicates with the lower end of the duct 30 is connected to the upper part of the mist generator 41 . A mist spray plate 43 is provided at the upper end of the communicating pipe 42 at a predetermined interval to cover the upper part of the communicating pipe 42. The mist spray plate 43 is formed in a roof shape with a high center and sloping downward on both sides.

[0016] The space 40 also contains a water tank 44 for storing water to be sent to the mist generator 41. The water tank 44 is connected to the mist generator 41 via a water supply pipe 45. A water supply pump 46 is provided midway along the water supply pipe 45.

[0017] [1-2. Effect] Next, the operation of the first embodiment will be described. First, water supply pump 46 is driven to send water from water tank 44 to mist generator 41 via water supply pipe 45. Mist generating section 47 and mist fan 48 of mist generator 41 are driven to cause mist generator 41 to generate mist. The mist generated by the mist generator 41 is sent upward through the communication pipe 42 and hits the mist-spraying plate 43. The mist that hits the mist-spraying plate 43 flows laterally along the mist-spraying plate 43 and toward the inner surface of the duct 30.

[0018] This mist flows along the inner surface of the duct 30, comes into contact with the soil 32 through the mesh portion of the pot portion 31, and is sent upwards in the duct 30 containing naturally occurring bacteria (microorganisms) in the soil 32. The mist sent to the upper part of the duct 30 then flows onto the upper surface of the table top 10 via the mist diffusion plate 33 .

[0019] Here, naturally occurring bacteria and harmful bacteria such as pathogenic bacteria live on the top surface of the table top 10. In this embodiment, the mist flowing from the mist generator 41 through the duct 30 is sent to the table top 10 containing naturally occurring bacteria, so that the naturally occurring bacteria on the table top 10 can be increased. By placing the top surface of the table top 10 in such an environment, naturally occurring bacteria, harmful bacteria, and human-derived bacteria will compete for nutrient sources present in the room where the mist supply device 1 is installed and on the top surface of the table top 10. Therefore, naturally occurring bacteria grow together with harmful bacteria, creating an environment where the naturally occurring bacteria and harmful bacteria compete with each other, preventing the growth of only harmful bacteria.

[0020] In addition, since the partition plate 22 is provided with an inclined surface 23, condensation caused by mist accumulating on the upper surface of the partition plate 22 and water dripping from watering the soil 32 are collected by the inclined surface 23 at the drain outlet 24 and discharged into the drain receiver 25 via the drain hose 26.

[0021] The mist device in this embodiment may operate continuously, or may be controlled to operate at predetermined intervals such as every 10 minutes, or may be controlled to operate more frequently at night. Such an operation can be controlled by a control device that controls the operation of the mist generating unit 47 and the mist fan 48, by managing the operation using a timer.

[0022] [1-3. Effects, etc.] As described above, the mist supply device 1 in this embodiment includes a mist generating system 20, which includes a mist generating device 41 that supplies mist and a duct 30 (mist supply section) through which the mist sent from the mist generating device 41 passes, and soil is exposed in the duct 30. As a result, the mist generated from the mist generator 41 comes into contact with the soil 32 as it passes through the duct 30 and is blown out containing naturally occurring bacteria in the soil 32, so the blown out mist creates an environment in which naturally occurring bacteria and harmful bacteria compete with each other. This makes it possible to prevent only harmful bacteria from growing in the environment around the duct 30. Harmful bacteria include pathogenic bacteria and opportunistic bacteria of human origin.

[0023] In addition, in the mist supply device 1 of this embodiment, the mist generating system 20 comprises a box-shaped main body 21, a table top 10 is provided on at least one side of the main body 21, a partition plate 22 is provided in the vertical center of the main body 21, a mist generating device 41 is provided below the partition plate 22, and a duct 30 (mist supply section) is arranged above the partition plate 22 to send the mist generated from the mist generating device 41 above the table top 10. As a result, by sending mist generated from mist generator 41 provided below partition plate 22 to duct 30, mist containing naturally occurring bacteria can be sent from the upper part of duct 30 to table top 10. As a result, an environment can be created on the upper surface of table top 10 where naturally occurring bacteria and harmful bacteria are in competition with each other, and the proliferation of only harmful bacteria on table top 10 can be suppressed.

[0024] In addition, in the mist supply device 1 of this embodiment, two table tops 10 are provided on both sides of the main body 21, and a mist diffusion plate 33 is provided at the upper end of the duct 30 to guide the mist to each table top 10. This allows the mist sent from the duct 30 to be efficiently sent to the two table tops 10 by the mist diffusion plate 33.

[0025] In addition, the mist supply device 1 of this embodiment is provided with a connecting pipe 42 that sends the mist generated from the mist generating device 41 to the lower end portion of the duct 30 (mist supply section), and a mist dispersion plate 43 is provided at the upper end portion of the connecting pipe 42 to guide the mist to the inner surface side of the duct 30. As a result, the mist sent from the mist generator 41 to the communication pipe 42 can be guided by the mist dispersing plate 43 to the inner surface of the duct 30. Therefore, by guiding the mist to the inner surface of the duct 30, it is possible to make it easier for the mist to come into contact with the soil 32 exposed to the duct 30, and the mist can efficiently contain naturally occurring bacteria.

[0026] In addition, in the mist supply device 1 of this embodiment, the upper surface of the partition plate 22 is an inclined surface 23 that is inclined to one side, and a drain outlet 24 is provided at the lowest part of the inclined surface 23 of the partition plate 22. This allows condensation caused by mist accumulating on the upper surface of the partition plate 22 and water dripping from watering the soil 32 to be collected at the drain outlet 24 by the inclined surface 23, and then discharged to the outside through the drain outlet 24.

[0027] (Embodiment 2) Next, a second embodiment of the present disclosure will be described. [2-1.Configuration] Fig. 4 is a side cross-sectional view showing the mist generating device 41 in embodiment 2. Fig. 5 is a plan view showing the mist generating device 41 in embodiment 2. 4 and 5, in this embodiment, the mist supply device 1 includes a mist generating system 120 and a mist feeding device 50. The mist generating system 120 includes a box-shaped main body 121, and a mist generating device 141 is housed inside the main body 121.

[0028] As in the first embodiment, the mist generator 141 includes an ultrasonic mist generator 147 and a mist fan 148 for supplying the mist generated from the mist generator 147. Inside the main body 121, a water tank 144 for storing water to be sent to the mist generator 141 is housed. The water tank 144 is connected to the mist generator 141 via a water supply pipe 145. A water supply pump 146 is provided midway along the water supply pipe 145. The mist generating device 141, the main body 121, the water tank 144, the water supply pipe 145, and the water supply pump 146 constitute the mist generating system 120.

[0029] A mist supply device 50 is disposed on one side of the mist generating system 120. The mist supply device 50 includes a box-shaped bowl 51 having approximately the same length as the mist generating system 20. Pot 51 contains soil 52. Inside pot 51, there is disposed mist supply pipe 53 serving as a mist supply section, which may be, for example, a Netron pipe with a mesh-like outer surface. The mist supply pipe is composed of two mist supply pipes 53, 53 disposed at a predetermined interval in the width direction of pot 51. One end of the mist supply pipe 53 is a mist outlet 54 exposed to the outside from the top surface of the soil 52, and the other end is a connecting port 55 that passes through the inside of the soil 52 and is exposed on one side of the pot 51. A mist generator 141 is connected to a connection port 55 of the mist supply pipe 53 via a connection pipe 56 .

[0030] A lid 57 is provided above the mist supply device 50 and the mist generation system 120. The lid 57 covers the entire upper surface of the mist supply device 50 and the mist generation system 120, and is formed so as to expose only the mist outlet 54 portion. The top surface of the lid 57 can be used as a bench for indoor users to sit on. The lid body 57 may be provided over a wider area than the mist supply device 1. By providing the lid body 57 over such a wider area, the area that can be used as a bench can be expanded. A fan (not shown) may be provided at the end of the lid 57. The mist blown out from the mist outlet 54 can be spread over the upper surface of the lid 57 by this fan. The lid 57 may also be formed to expose a portion of the mist supply device 50. For example, the lid 57 may be formed to expose a portion or all of the soil 52 and cover the rest, and plants may be planted in the soil 52 exposed by the lid 57.

[0031] [2-2. Effect] Next, the operation of the second embodiment will be described. In this embodiment, first, water supply pump 146 is driven to send water from water tank 144 to mist generator 141 via water supply piping 145. Mist generating section 147 and mist fan 148 of mist generator 141 are driven to cause mist generator 141 to generate mist. The mist generated by the mist generator 141 is sent to the mist supply pipe 53 of the mist supply device 50 via the connecting pipe 56 . The mist sent to the mist supply pipe 53 is blown out into the room from the mist outlet 54.

[0032] In this case, since the mist supply pipe 53 is buried in the soil 52 , when air flows through the mist supply pipe 53 , the air contains bacteria naturally occurring in the soil 52 . Then, the air containing naturally occurring bacteria is blown out from the mist outlet 54 onto the upper surface of the lid 57.

[0033] By creating an environment in which the air above the lid 57 contains naturally occurring bacteria, an environment can be created in which naturally occurring bacteria and harmful bacteria compete for the nutrient sources present on the top surface of the lid 57, thereby creating an environment in which naturally occurring bacteria and harmful bacteria are in antagonism.

[0034] [2-3. Effects, etc.] As described above, in the mist supply device 1 of this embodiment, the mist supply pipe 53 (mist supply section) is formed in the shape of a pipe with one end connected to the mist generating device 41 and the other end having a mist outlet 54 (outlet) inside the room, and the mist supply pipe 53 is buried in the soil 52 placed in the pot 51 and is provided with a mist generating system 120 and a lid 57 that covers the top of the soil 52. As a result, when the mist generated by the mist generator 41 flows through the mist supply pipe 53, air containing naturally occurring bacteria that comes into contact with the soil 52 can be blown out from the mist outlet 54 onto the upper surface of the lid 57, creating an environment on the upper surface of the lid 57 where naturally occurring bacteria and harmful bacteria compete with each other. This makes it possible to prevent only harmful bacteria from growing on the upper surface of the lid 57. Harmful bacteria include pathogenic bacteria and opportunistic bacteria of human origin.

[0035] (Other embodiments) As described above, the above-mentioned first embodiment has been described as an example disclosed in the present application.
