Description

  The present invention relates to a space sterilization apparatus that performs sterilization of air in an internal space of a building, and particularly relates to a space sterilization apparatus that can easily cope with sterilization of a large space.

  In general, it has been proposed to suppress the growth of viruses floating in the air by humidifying the air in the interior space of the building.

  Although such a technique of humidifying air has made it possible to expect a certain degree of virus growth suppression effect, there is a demand for active sterilization that further reduces the virus.

  Conventionally, in order to meet the above-described demand, a housing is provided with a gas flow path having an intake port and an exhaust port, and a vaporizer and sterilization disinfection for reducing the virus are provided in the gas flow path. A disinfectant storage device storing a odorant and a blower fan that generates an air flow are provided, and the disinfectant and deodorant released from the disinfectant storage device by the air flow generated by the blower fan Is discharged into the air from the exhaust port of the housing together with the vaporized liquid generated in the vaporizer, and a humidifying action and a sterilizing and deodorizing action are simultaneously performed, thereby providing a sterilizing and deodorizing effect in the air. It has been proposed to increase (see Patent Document 1).

JP 2012-149812 A

  Although the above-described conventional technique can enhance the sterilization and deodorizing effect in the air, the following problems to be improved remain.

  That is, in the above-described technique, it is effective to increase the flow velocity of the air flow generated by the blower fan in order to diffuse the gas mixture of the vaporized liquid and the sterilizing deodorant over a wide range in the air. .

  However, since the discharge amount of the gas mixture and sterilization deodorant mixed gas into the air depends on the flow velocity of the air flow, increasing the flow velocity of the air flow increases the discharge amount of the mixed gas. In particular, since the amount of the sterilizing deodorant that can be stored in the sterilizing agent storage device is limited, as described above, when the amount of release increases, a stable sterilizing and deodorizing effect is achieved. It is a problem that it cannot be maintained for a long time.

  Therefore, it is necessary to frequently replace the disinfectant and deodorant in the disinfectant storage container, and it is assumed that not only the maintenance management becomes complicated, but also the maintenance cost increases.

  In order to solve such conventional problems, the present invention suppresses the consumption of the antibacterial substance while diffusing the antibacterial substance over a wide range, and maintains the sterilization and deodorizing effect of the space as long as possible. It is an object of the present invention to provide a spatial sterilization apparatus that can handle such a situation.

  Here, the optimal liquid supply amount can be set by adjusting the liquid supply amount by the pump in accordance with the gas supply amount by the blower.

  Then, the liquid discharge hole is supplied to the liquid carrier by dropping the liquid by making the liquid discharge hole face above the liquid carrier of the vaporization means at an interval, or the liquid discharge hole The liquid can be directly supplied to the liquid carrier in contact with the liquid carrier.

  With the former supply method, supply based on the supply amount set by the pump is possible, and with the latter supply method, the liquid is continuously supplied by the capillary action of the liquid carrier itself. It becomes possible.

  Further, the tank is formed with a liquid reservoir portion located below the inner surface of the bottom portion at the bottom thereof, and the bottom portion of the tank is formed to be inclined downward toward the liquid reservoir portion. The suction part may be arranged in the liquid reservoir part.

  With such a configuration, when the remaining amount of the liquid stored in the tank decreases, the liquid is collected by flowing into the liquid pool due to the inclination of the bottom of the tank, and this collected The liquid can be sucked from the suction portion by the pump and sent to the vaporizing means.

  Thereby, even when the liquid stored in the tank is reduced, the remaining liquid can be reliably sent to the vaporizing means, and the liquid can be used without waste.
