  The cross flow fan 3 includes a fan 3a and a motor 3b that rotationally drives a rotating shaft 3c of the fan 3a. The cross-flow fan 3 extends along the rotation shaft 3c, and has a wide suction port and a blower outlet having a length substantially equal to the axial length of the fan 3a. Since the cross flow fan 3 has a wide inlet and outlet, it can send out a wide range of air currents, and a plurality of ion generators 4 can be installed in the lateral direction. In the present embodiment, a structure in which two ion generators 4 are juxtaposed is shown.

  The ion generator 4 includes two ion generators in a rectangular parallelepiped body 4d. One of the two ion generators is a positive ion generator 4a, and the other is a negative ion generator 4b. The positive ion generation part 4a and the negative ion generation part 4b are provided with a needle-like metal electrode having a pointed portion protruding from the main body 4d, and an arched cover 4c is provided to cover the positive ion generation part 4a and the negative ion generation part 4b. ing.

Positive ions generated from the positive ion generator 4a are H ⁺ (H ₂ O) _m (m is an arbitrary natural number), and negative ions generated from the negative ion generator 4b are O ₂ ⁻ (H ₂ O) _n ( n is an arbitrary natural number), and both positive and negative ions are sent to the air, so that they adhere to airborne bacteria and viruses in the air, and a hydroxyl radical (.OH) is generated by the reaction that takes place. Sterilizes airborne bacteria and inactivates viruses.

  FIGS. 6 and 7 show the flow of wind on the bed when the ion generator 2 is installed as shown in FIG. FIG. 6 is a top view schematically showing the state of the airflow, and corresponds to the case seen from above. FIG. 7 is a side view schematically showing the state of airflow, and corresponds to the case seen from the side. In the figure, it is assumed that the airflow indicated by solid arrows is on the near side of the screen, and the airflow indicated by dotted arrows is on the far side of the screen in each figure.

  First, air containing ions is blown from the ion generator 2 installed on the headboard 1a toward the footboard 1b, and ions are generated from the ion generator 2 installed on the footboard 1b toward the headboard 1a. Contained air is blown out. The airflow sent from the ion generator 2 installed on the headboard 1a toward the footboard 1b is caused by the suction airflow of the ion generator 2 installed on the footboard 1b along the footboard 1b. It diffuses toward the center of the inner bed 1.

  Similarly, the airflow sent from the ion generator 2 installed on the footboard 1b toward the headboard 1a is moved along the headboard 1a by the suction airflow of the ion generator 2 installed on the headboard 1a. It diffuses toward the center of the bed 1 inside the board 1a. Thereby, ions can be diffused on the bed 1 without directing the wind direction of the ion generator 2 toward the center of the bed 1.

  In addition, when the bed 1 is installing frames, such as a metal pipe, in the head side edge part and the leg side edge part, it is good to provide the wall part for guiding an airflow on a bed in each frame. By doing in this way, a headboard and a footboard are comprised, and it becomes possible to cover the upper part of the bed 1 including an end part on a head side and an end part on a leg side with an ion stream.

(Embodiment 2)
8 is a schematic perspective view of a bed with an ion generator according to Embodiment 2 of the present invention, FIG. 9 is a perspective view showing the appearance of the ion generator, FIG. 10 is a partial front perspective view of the ion generator, and FIG. FIG. 12 is a cross-sectional view taken along line XI-XI in FIG. 10, FIG. 12 is a top view schematically showing the state of air flow, and FIG. 13 is a side view schematically showing the state of air flow.

  In the first embodiment, the ion generator 2 has the downward suction port 2a. However, in the second embodiment, the ion generator 20 has a lateral suction port 20a on one side surface or both side surfaces of the housing 20c. This is different from the first embodiment. As in the first embodiment, the air outlet 20b faces forward, and the housing 20c includes an operation unit 20d.

  Unlike the first embodiment, the ion generator 20 includes two sirocco fans 30 instead of the cross flow fan 3. The sirocco fan 30 includes a fan 30a, a casing 30c that surrounds the fan 30a, and a motor 30b that rotates the fan 30a. The motor 30b is a double-axis motor, and the fan 30a and the casing 30c of each sirocco fan 30 are arranged on both sides of the motor 30b, and the output shaft of the motor 30b is connected to the rotation shaft of each fan 30a.

  FIGS. 9 and 10 show the case where the suction ports 20a that are horizontally oriented are provided on both side surfaces of the housing 20c of the ion generator 20, but the suction ports 20a are provided only on one side surface of the housing 20c. In this case, as shown in FIG. 8, the suction port 20a is provided so as to be located inside the bed. When the ion generator 20 is installed as shown in FIG. 8, only the position of the suction port 20a is different from that in the first embodiment, and an air flow is configured as in the first embodiment.

  FIGS. 12 and 13 show the flow of wind on the bed when the ion generator 20 is installed as shown in FIG. In the figure, it is assumed that the air flow indicated by a solid line is on the front side of the screen of each figure, and the air flow indicated by a dotted line is on the back side of the screen.

  First, air containing ions is blown from the ion generator 20 installed on the headboard 1a toward the footboard 1b, and ions are generated from the ion generator 20 installed on the footboard 1b toward the headboard 1a. Contained air is blown out. The airflow sent from the ion generator 20 installed on the headboard 1a toward the footboard 1b is along the footboard 1b by the suction airflow directed toward the suction port 20a of the ion generator 20 installed on the footboard 1b. And diffuse toward the center of the bed 1. Similarly, the airflow sent from the ion generator 20 installed on the footboard 1b toward the headboard 1a is caused by the suction airflow toward the suction port 20a of the ion generator 20 installed on the headboard 1a. It diffuses toward the center of the bed 1 along 1a. Thereby, ions can be diffused on the bed 1 without directing the wind direction of the ion generator 20 toward the center of the bed 1.

  In addition, the form which has the suction inlet of an ion generator in the lower surface and side surface of a housing | casing is also possible combining Embodiment 1 and Embodiment 2. FIG. In this case, the same airflow as in the first embodiment or the second embodiment is formed. Since the number of suction ports is large and the suction area is increased, airflow is efficiently induced by suction, and the efficiency of diffusing ions on the bed is improved.

(Embodiment 3)
FIG. 14 is a schematic perspective view of a bed with an ion generator according to Embodiment 3 of the present invention, and FIG. 15 is a top view schematically showing the state of airflow. In the first and second embodiments, the example in which the bed 1 to which the ion generators 2 and 2 are attached is provided with the headboard 1a and the footboard 1b for inducing the airflow has been described. This is different from the first and second embodiments in that only the head board 10a for guiding is installed. Specifically, the footboard 10b in the figure has only a frame, and an opening 10b1 through which airflow passes is formed in the central portion.

  Although it is inferior to Embodiments 1 and 2 in that the purified air is supplied to the periphery of the bed, it is considered that the person lying on the bed 10 is most affected by the air purification when the air is sucked from the nose or mouth. This is an implementation method that can be fully used. That is, if ions can be supplied to the vicinity of the headboard 10a where a human head is located, the purpose is achieved. Therefore, the ion generator 2 is installed on the footboard 10b, and the air flow containing ions is transferred to the head side. In addition, by guiding the airflow toward the center of the bed 10 with the headboard 10a, ions can be present at a high concentration around the human head.

  The ion generator 2 is installed on both the headboard 10a and the footboard 10b. However, since the footboard 10b has no plate portion for inducing airflow, the airflow blown from the ion generator 2 installed on the headboard 10a It pierces through the opening 10b1 of the footboard 10b and does not return to the head side. On the other hand, on the inner side of the headboard 10a, the blown airflow collides with the headboard 10a from the ion generator 2 installed on the footboard 10b, and is guided in the lateral direction to have high concentration of ions. Although it is not complete in that the upper surface of the bed floor 10c is covered with an air stream containing ions, there is no practical problem because most of the bed floor 10c is covered with an air stream containing ions.

(Embodiment 4)
FIG. 16 is a schematic perspective view of a bed with an ion generator according to Embodiment 4 of the present invention.
In Embodiment 1-3, an example in which ion generators are installed on headboards 1a and 10a and footboards 1b and 10b has been described. However, in Embodiment 4, an ion generator is installed only on a footboard. This is different from the embodiment 1-3.

In order to increase the amount of ions generated by the ion generator, a method of increasing the voltage applied to the ion generator, a method of increasing the number of ion generators, a method of increasing the amount of air passing through the ion generator, and these methods Made possible by the combination of

  When the ion generator 21 whose ion generation amount is approximately doubled is installed only on the foot board 1b, it is possible to install a simple blower 5 that does not have an ion generation unit on the head board 1a. A high-concentration ion can be supplied to the inner periphery of the headboard 1a of the bed 1 where the human head is located by an air flow including ions from the ion generator 21 installed on the footboard 1b. By sucking the blower 5 and guiding the airflow with the head board 1a, ions can be present at a high concentration around the human head, as in the embodiment 1-3. Further, by sending high-concentration ions near the head by the blower 5 toward the footboard 1b, ions are also supplied to the leg side and refluxed by the ion generator 21 and the footboard 1b installed on the footboard 1b. It can be made. Therefore, the airflow is formed in the same manner as in the first and second embodiments.

  The ion generator 22 used in the fifth embodiment has substantially the same structure as the ion generator 20 used in the second embodiment, and the housing 22c has an operation portion 22d, and is horizontally disposed on both side surfaces of the housing 22c. A suction port 22a is provided. The ion generator 22 is provided with an air guide plate 22e that guides an airflow blown out from one of the two sirocco fans 30 to the air outlet 22b. The air guide plate 22e that guides the ion air flow downward is preferably installed so as to be on the center side of the bed 1 at the air outlet 22b.

  Most of the ions sent from the ion generator 22 installed on the headboard 1a are sent toward the footboard 1b, and the suction airflow of the blower 5 installed on the footboard 1b and the center of the bed 1 by the footboard 1b. To spread. Some ions sent from the ion generator 22 installed on the headboard 1a are guided to the periphery of the headboard 1a by the air guide plate 22e, and are supplied at a high concentration around the headboard 1a where the human head is located. . At the same time, the blower 5 installed on the footboard 1b can return the ions sent toward the footboard 1b from the leg side to the head side, and the airflow is the same as in the first, second, and fourth embodiments. It is formed.
