Description

  The present invention relates to a humidifier.

  FIG. 1A is a perspective view of a known technique, and FIG. 1B is a perspective view of a dipping part and a water receiving part of the known technique.

  As shown in FIGS. 1A and 1B, the humidifier 1 includes a tank 2, a blower fan (not shown) that is rotated by a fan motor, and a humidification container 4 that stores the water in the tank 2, and the humidification thereof. The container 4 has a partition 8 that partitions the water receiving portion 5 and the immersion portion 7. The partition 8 includes an opening 9 through which the water receiving portion 5 and the immersion portion 7 communicate with each other. The water receiver 5 includes a tank 2 and a float 10, and the immersion unit 7 includes a humidifying filter 11.

  When the user activates the humidifier 1 and the blower fan is rotated by the rotation of the fan motor, the water in the water receiving part 5 flows into the immersion part 7 through the opening 9, whereby the water level of the immersion part 7 is normally The water level becomes higher than the water level of the water receiving part 5 at the same time. Since the negative pressure which the water of the immersion part 7 does not flow backward to the water receiving part 5 through the opening 9 arises by a ventilation fan, when the ventilation fan is rotating, said water level is maintained.

  If the water in the tank 2 is used up during the operation of the humidifier 1, the supply of water to the water receiver 5 is lost. Thereby, the water level of the water receiving part 5 falls gradually, and the float 10 also falls simultaneously. When the float 10 is lowered to a position lower than a predetermined position, the humidifier 1 transmits a water injection signal and the rotation of the fan motor is stopped. At that time, when the blower fan is stopped, the negative pressure disappears, and the water in the immersion part 7 flows through the opening 9 of the partition 8 so that the water level in the immersion part 7 and the water level in the water receiving part 5 become the same. It flows backward to the receiving part 5. At the same time as the water level of the water receiving part 5 rises, the float 10 also rises. At that time, when the float 10 rises to a position higher than a predetermined position, the water injection signal is also stopped and the blower fan automatically rotates. With the rotation of the blower fan, the water in the water receiving portion 5 is returned to the immersion portion 7 through the opening 9 again. Thereby, the water level of the water receiving part 5 falls again, the float 10 falls to a position lower than a predetermined position, the rotation of the blower fan is stopped again, and the humidifier 1 transmits a water injection signal again. As described above, there are cases where the water injection signal is repeatedly transmitted and stopped, which is not easy to use.

  2A is a perspective view of the present invention, FIG. 2B is a perspective view of the present invention with the case removed, FIG. 3 is a perspective view of the blowing means and the humidifying means of the present invention, and FIG. 4 is the present invention. It is a perspective view of an immersion part, a water receiving part, and a detection means.

  As shown in the figure, the humidifier 20 according to the present invention includes a case 30 having a suction port 31 and a blowout port 32, humidification means 40 provided in the case 30, and air sucked from the suction port 31. Is provided with a blowing means 50 that blows out from the outlet 32 via the humidifying means 40, a water level detecting means 60 that detects the water level of the humidifying means 40, and a control means 70 that controls the blowing means 50. The humidifying means 40 includes a humidifying container section 41 that can store water, a tank section 42 that supplies water to the humidifying container section 41, and a humidifying filter section 43 that is partially immersed in the water in the humidifying container section 41. Yes. The humidifying container portion 41 is partitioned by a partition portion 44 into a water receiving portion 411 in which the tank portion 42 is mounted and an immersion portion 412 in which the humidifying filter portion 43 is provided. And an opening 440 through which water passes. The immersion part 412 has a float part 61 provided in the air passage and movably in the vertical direction. The water level detection means 60 includes a float unit 61 having buoyancy and a detection unit 62 that detects the position of the float unit 61. When the detecting unit 62 detects that the float unit 61 is below a predetermined height during the operation of the blowing unit 50, the control unit 70 stops the operation of the blowing unit 50 and transmits a water injection signal.

  When the air blowing means 50 is driven, the immersion portion 412 becomes negative pressure. Due to this negative pressure, the water in the water receiving portion 411 is pulled toward the immersion portion 412, and the water level in the immersion portion 412 becomes higher than the water level in the water receiving portion 411.

  When all the water in the tank portion 42 is supplied to the water receiving portion 411, the supply of water to the water receiving portion 411 is stopped, so that the water level of the immersion portion 412 is gradually lowered and the float portion 61 is also lowered. Thus, if the float part 61 falls to a position lower than a predetermined position, the control means 70 will transmit a water injection signal and the operation | movement of the ventilation means 50 will be stopped. When the air blowing means 50 is stopped, the negative pressure disappears, and the water moves from the immersion portion 412 side to the water receiving portion 411 side, so that the water level of the immersion portion 412 further decreases. That is, the float portion 61 installed in the immersion portion 412 does not rise and the water injection signal does not stop again. Since there is no water to raise the float part 61, the water injection signal does not stop until the user puts water into the tank part 42.

  That is, since the water injection signal is not repeatedly transmitted and stopped, the user-friendly humidifier 20 can be provided.
