  As shown in FIG. 14, when water at a predetermined water level is stored in the water storage unit 222 of the humidifying tray 220 and the humidifying hot air blower 100 can be operated normally, the water level of the humidifying tray 220 is indicated by a water level line 290. The float 270 rises to the vicinity of the upper end of the partition wall 241 of the float tank 240, the float 270 contacts the regulating piece 241a of the float tank 240, and the reed switch 280 is in the ON state.

  In this state, the humidifying hot air blower 100 is in a state in which a humidifying operation is possible. When the water level of the humidifying tray 220 decreases and the water level drops below the water level line 291, the reed switch 280 is turned OFF and the humidifying operation is automatically stopped. Is done.

  When the humidifying / heating air blower 100 is moved during the humidifying operation, when the float bath 240 side (left side) of the humidifying / heating air blower 100 is inclined so as to be lowered, as shown in FIG. The water level line 290 at 240 is higher than the normal state, the float 270 is in contact with the regulating piece 241a of the float tank 240, and the reed switch 280 is maintained in the ON state.

  On the other hand, when the float tank 240 side (left side) is inclined to be higher, the water in the water storage section 222 flows back to the water receiving section 221 and the water level line 290 of the water storage section 222 is lower as shown in FIG. Become. However, the water level in the float tank 240 is determined by the water remaining in the float tank 240 and the communication path 242 due to the barrier 243 provided at the entrance of the communication path 242, so that the water level line 292 in the float tank 240 is Since the float 270 can be maintained at a higher position by being maintained higher, the reed switch 280 can be maintained in the ON state.

  As described above, in this state, the water storage unit 222 of the humidifying tray 220 and the float tank 240 form different water levels.

  As described above, since the reed switch 280 of the water level detection unit 260 can be kept in the ON state even when the humidifying hot air fan is tilted in the horizontal direction, for example, when the humidifying hot air fan is moved during operation, It is possible to prevent the operation of the warm air machine from being stopped carelessly.

  In addition, the humidification hot air fan in this Embodiment is set so that the reed switch 280 is turned off and the humidification operation is stopped when tilted by 10 degrees or more to the left and right.

<5> Operation and Action of Humidifying Hot Air Fan When using the humidifying hot air fan 100, first, a water filling tank 210 is charged as a preparatory work. When performing the water filling operation, the water supply tank 210 can be turned upside down, and the handle 213 can be rotated to the upright position and fixed by the stopper 211b.

  In this state, the lid 212 is removed from the tank body 211, and water is filled into the tank body 211 from the water supply port 211a. The filling operation is finished by closing the lid 212 after the filling.

  Next, the humidifying filter 230 and the filter tray 250 are set in the water storage section 222 of the humidifying tray 220 and pushed from the tray opening 112 on the back surface of the main body 110. When the humidifying tray 220 is pushed to a predetermined position, it is fixed to the main body 110 by the lock mechanism 224.

  Next, hold the water supply tank 210 filled with water with the handle 213 in an upright state, insert the lid 212 from the tank opening 111 into the water receiving part 221 of the humidifying tray 220, and press the upper part against the tank opening 111. Accordingly, the locking portion 214b of the closing member 214 is locked to the main body 110, and the water supply tank 210 is fixed to the main body 110.

  In the above preparatory work completion state, the water in the water supply tank 210 flows into the water receiving part 221 of the humidifying tray 220 and flows into the water storage part 222 and the float tank 240, and stops when it reaches a predetermined water level. In this state, about 1/3 of the lower side of the humidifying filter 230 is submerged, and the entire filter material 232 is in a water absorbing state due to capillary action.

  In a state where the water storage unit 222 reaches a predetermined water level and water supply is stopped, the float 270 is lifted to a position where it abuts on the restriction piece 241a of the float tank 240, and the reed switch 280 is in the ON state, and the operation unit The power switch 121 of 120 can be operated.

  When starting the operation of the humidifying / hot air fan 100, first, the power switch 121 of the operation unit 120 is set to “ON”, and then a preferred operation mode is selected. There are three basic operation modes: “warm air”, “humidification”, and “electrostatic atomization”. In addition to this, “humidification hot air” that simultaneously performs “warm air” and “humidification”. There are driving modes. In addition to the single operation mode, the operation mode of “electrostatic atomization” can be operated simultaneously with other “hot air”, “humidification” and “humidification hot air” operation modes. .

  When operating in the hot air mode, either the hot air continuous switch 122 or the hot air room temperature switch 123 is selected and operated. When the hot air continuous switch 122 is selected, the humidifying hot air fan 100 blows out hot air regardless of the room temperature with the heater 170 having a capacity of “strong” or “weak”. When the hot air room temperature switch 123 is selected, the capacity of the heater 170 is switched in conjunction with the room temperature so as to keep the room temperature at a predetermined temperature.

  When the operation in the warm air mode is performed, the damper 200 is disposed at the position D where the humidified air passage 153 is closed, and the warm air is supplied only to the warm air passage 152 and blows out directly from the outlet 140. In this case, the warm air blown out is in a state of being dried at a high temperature, and this mode is suitable for heating for a short period of time or for the purpose of drying.

When performing the operation in the humidification mode, the humidification switch 124 is operated. In the case of operation in the humidification mode, the capacity of the heater 170 is set to a low capacity (about 600). The damper 200 is disposed at a position C where the warm air is mainly blown to the humidification air passage 153.
53, the hot air in a dry state that has passed through the hot air passage 152 and the humidified air that has passed through the humidifying air passage 153 and is humidified by the humidifying unit 190 are mixed in front of the outlet 140, Blow out from 140.

  In this mode, a part of the warm air is blown out directly from the warm air passage 152, thereby obtaining an effect of efficiently sucking and blowing out the humid air mixed in front of the air outlet 140 by the hot air having a high flow velocity. be able to.

  When performing the humidified warm air mode operation in which the warm air mode operation and the humidification mode operation are performed simultaneously, the humidification switch is operated with either the hot air continuous switch 122 or the warm air room temperature switch 123 as described above.

  In the operation in the humidified hot air mode, the position of the damper 200 and the air blowing state are the same as in the humidifying operation, but the capacity of the heater 170 is operated at a maximum capacity of 1200 W. Therefore, it is the most suitable mode when warm air moderately humidified blows out and the room is comfortably heated for a long time.

  When performing the operation in the electrostatic atomization mode, the electrostatic atomization switch 125 is operated. By operating the electrostatic atomization switch 125, the electrostatic atomization unit 181 is energized, and the electrostatic atomization unit 181 generates nanometer-sized charged fine particles from moisture contained in the air blown from the blower 160. Then, the air containing the charged fine particles is blown out from the air outlet 140.

  Operation in electrostatic atomization mode can be performed simultaneously with each operation mode of hot air operation, humidification operation, and humidification hot air operation, in addition to being implemented as a single operation. Deodorizing, sterilizing, and sterilizing effects can be exerted on odor components and fungi that float and adhere to the wall and floor surfaces.

  When the operation is stopped, the operation of the humidifying hot air fan 100 is stopped by operating the power switch 121 to “OFF”.

  In a state where the operation is stopped, replenishment of water in the water supply tank 210, maintenance of the humidification filter 230, and the like can be performed. When removing the water supply tank 210 from the main body 110, the upper part can be pulled out by pulling the handle 214 d with a finger while pulling the puller 214 d while pushing the unlocking button 214 c installed on the upper part of the closing member 214. It can be removed from the main body 110 by moving and holding the holding portion 213a and pulling it upward.

  When the humidifying tray 220 is removed from the main body 110, it can be pulled out from the main body 110 by placing a finger on the pulling handle 225 on the back of the humidifying tray 220 and pulling it strongly.

  When performing humidification filter 230 maintenance, the humidification filter 230 and the filter tray 250 are removed from the humidification tray 220 and washed with water, so that scales and dust accumulated in the filter material can be removed.

  As described above, the humidifying hot air fan 100 according to the present embodiment is configured so that the humidifying tray 220 and the water supply tank 210 can be attached and detached from the opening provided on the back surface of the main body 110, so that the water supply tank 210 can be attached and detached. In this case, it is not necessary to lift the water supply tank 210 to a high position, and it can be attached and detached from the tank opening 111 at a lower position of the main body 110, so that the attachment and detachment work can be performed safely and easily.

In particular, the water supply tank 210 has a tank body 211 and a closing member 214 formed as an integrated structure, and can be attached and detached with a single touch, so that the attaching and detaching work can be easily performed and the tank body 211 is concealed by the closing member. As a result, the design of the external appearance of the humidifying hot air fan can be improved.

  Moreover, the water supply work to water supply tank 210 can be easily performed by having set it as the structure which can become independent in the state which inverted water supply tank 210. FIG.
