Description

  The present invention relates to an air cleaner having a humidifying function.

  Conventionally, in this type of air purifier, an air purifying unit having an air purifying filter on the upstream side of the air flow path as in Patent Document 1 and a humidifying unit having a humidifying unit on the downstream side thereof are arranged from the suction port. A device is disclosed in which air taken into a main body case is purified by an air purifying filter, then humidified by a humidifying unit, and discharged from the blower outlet to the outside of the main body case.

  Further, Patent Document 2 discloses a humidifying channel that selectively takes in a part of the purified air, and a humidifying means disposed in the humidifying channel, in addition to the outlet channel that blows out the purified air. And an air outlet that blows out the air humidified by the humidifying means to the outside of the main body case.

  However, in Patent Document 1, since the amount of air to be humidified depends on the flow rate of air flowing through the air purifying filter, if the indoor air becomes dirty and the amount of purified air is increased, the amount of humidification increases regardless of whether or not humidification is necessary. In order to increase the amount of humidification even when the room air is clean, there is a drawback that the operation noise increases because the amount of purified air is increased.

  Further, in Patent Document 2, in order to provide a humidified air outlet for purified air at a position different from the outlet for purified air, noise is increased due to restrictions on the installation location, changes in blowing efficiency, and purification performance is reduced. There were drawbacks.

  The objective of this invention is providing the air cleaner with a humidification function which can solve the said subject and can perform increase / decrease in the humidification amount as needed.

In order to achieve the above object, the present invention is characterized in that, in an air purifier having a cartridge water supply tank for supplying water to a vaporization filter, a fan motor drives a centrifugal fan including a turbo fan and the centrifugal fan. In addition, the electric motor placed so as to enter the central part of the centrifugal fan, the suction plate that guides the suction flow of the centrifugal fan, and the spiral shape surrounding the centrifugal fan and the gap between the centrifugal fan and the outer periphery toward the discharge port of and a casing, a cartridge water tank placed between the filter unit and the fan motor, the gap between the centrifugal fan the outer circumference is arranged to come narrower side, to the downstream side of the suction plate of the cleaning filter unit shutter of the air passage with a first passage passing through the vaporization filter unit, upstream of said fan motor In that is divided into a second flow path which does not pass through the more open are possible the vaporizing filter unit.

  According to the present invention, the air flow path to the fan motor suction plate on the downstream side of the purification filter unit is humidified by the flow path passing through the vaporization filter unit, and the flow rate by opening and closing the shutter of the flow path provided with the openable / closable shutter By adjustment, it is possible to provide an air cleaner with a humidifying function that can increase or decrease the humidification amount as necessary.

  Embodiments of the present invention will be described with reference to the drawings.

Further, it is placed on a support base 29 formed integrally with the lower part of the main frame 2.

  The front panel 4 has a hook (not shown) provided on the upper side hooked on the upper side of the front frame 3, and a locking projection (not shown) provided on the lower side on the lower side of the front frame 3. It is locked in the locking hole 30 and fixed. Because of such fixing, the front panel 4 can be easily removed during maintenance of the filter unit 5.

  As shown in FIGS. 2, 3, and 4, the fan motor 7 includes a centrifugal fan including a turbo fan 7 a and an electric motor 7 b that drives the centrifugal fan and is placed so as to enter inside the central portion of the centrifugal fan. . The front frame 3 has a suction plate 9 that guides the suction flow to the centrifugal fan.

  The main frame 2 has a spiral casing 8 that surrounds the centrifugal fan and has a gap extending from the outer periphery of the centrifugal fan toward the discharge port. A cartridge water supply tank 13 is placed between the filter unit 5 and the fan motor 7. The cartridge water supply tank 13 is arranged so that the gap with the outer periphery of the centrifugal fan is closer to the narrow side, and the vaporization filter 6 is arranged close to the cartridge water supply tank 13.

  In this way, the spiral casing 8 whose gap with the outer periphery of the centrifugal fan expands toward the discharge port, and the cartridge water supply tank 13 in which the cartridge water supply tank 13 is placed between the filter unit 5 and the fan motor 7 are connected to the outer periphery of the centrifugal fan. The cartridge water supply tank 13 can be substantially half buried in the main body frame 1 of the air purifier.

  For this reason, since the cartridge water supply tank 13 is substantially half buried in the main body frame 1 of the air purifier without enlarging the main body frame 1 of the air purifier, a compact and good-looking air purifier can be obtained. Can be provided.

  The storage of the cartridge water supply tank 13 will be described in more detail.

  As shown in FIGS. 3 and 4, the main frame 2 of the main body frame 1 has a tank housing recess 20 in which the cartridge water supply tank 13 is accommodated on the side surface. The cartridge water supply tank 13 is detachably attached to the tank housing recess 20. The cartridge water supply tank 13 includes a stopper (not shown) on the upper side. The cartridge water supply tank 13 is locked by a stopper so as not to be detached from the main body frame 1.

  The cartridge water supply tank 13 is formed using a transparent material. Thereby, the amount of water accumulated in the cartridge water supply tank 13 can be seen.

  The tank housing recess 20 is located on the back side of the filter unit 5. Moreover, the tank housing recess 20 is arranged so that the gap between the outer periphery of the centrifugal fan and the casing 8 is on the narrower side. Then, the vaporizing filter 6 is moved to the opposite side of the tank housing recess 20. With such an arrangement, even if the tank housing recess 20 is provided, the main body frame 1 can be made compact without being enlarged.

  As shown in FIG. 6, the vaporization filter unit 15 includes a vaporization filter 6, a vaporization filter case 18 that holds the vaporization filter 6, a storage water tank cover 19 that holds the vaporization filter case 18 in the storage water tank 14, and a storage water tank 14. Formed by. The vaporizing filter case 18 can be divided into two parts, and the inside can be easily cleaned. Further, the reservoir water tank cover 19 can be removed from the reservoir water tank 14, and the internal cleaning is facilitated.
