Description

  The present invention relates to a vaporizing humidifier that humidifies air by passing it through a humidifying filter wetted with water and discharges the air to the outside.

  This type of vaporizing humidifier generally has a water storage container for storing water, a humidification filter installed in the water storage container, external air is sucked, and the sucked air is passed through the humidification filter. It has a blower fan that discharges air humidified by the filter to the outside, and a motor that rotates the blower fan.

  Since the humidifying filter is installed in a water storage container containing water, the water in the water storage container is sucked up by the capillary action of the humidifying filter, and the humidifying filter is moistened with water. The air sucked by the blower fan is humidified when passing through the humidifying filter and discharged to the outside, and the humidifying filter loses moisture.

  The humidifying filter that has lost the moisture further sucks up the water in the water storage container, and the water in the water storage container decreases gradually. When the water in the water storage container is completely exhausted, the humidifying filter is dried, and when the humidifying filter is dried, the humidifying ability is lost. For this reason, before the humidifying filter loses the humidifying ability, water must be replenished in the water storage container to wet the humidifying filter.

  In the conventional humidifier, a water storage tank is separately provided to replenish water in the water storage container and moisten the humidification filter. When the water in the water storage container becomes low, water is sequentially transferred from the water storage tank to the water storage container. There is a type that supplies water and a type that provides a water inlet and directly supplies water into the water storage container from the outside through the water inlet when water is low.

  A humidifier of a type that has a separate water storage tank does not have to worry about replenishing water as long as water remains in the water storage tank. However, if the humidifier is operating, it will eventually run out of water. The tank must be refilled with water.

  When replenishing the water tank of this type of humidifier, the water tank must be removed from the humidifier, filled with water, and the water tank must be set in the humidifier again. However, this work is troublesome. Also, the water storage tank that contains water is quite heavy, so it is hard work for those who are weak.

  A humidifier of the type provided with a water inlet and directly replenishing water into the water storage container from the outside through the water inlet does not have the above-mentioned problems. However, since this type of humidifier is provided with a water injection port at a position avoiding the blower fan, motor, and electric system, it is difficult to form a large opening for the water injection port, and the opening of the water injection port becomes small.

  If the opening of the water inlet becomes small, water may accidentally spill around the water inlet and wet the floor, and in the worst case, the motor or electrical system may get wet and damage them. It was difficult to replenish water because it was necessary to replenish water with care not to spill water.

  The problem to be solved by the present invention is that the opening of the water injection port for supplying water to the water storage container cannot be formed large.

  In the present invention, in order to make it possible to form a large opening of the water injection port for replenishing water to the water storage container, the upper part of the motor is covered with a dome-shaped upper cover, and a peripheral ridge is formed at the peripheral part of the upper cover. The most important feature is that the crossing ridge is formed outward from the peripheral ridge so as to cross the flow of air discharged to the outside, and a water channel is formed from the crossing ridge to the water storage container. And

  Since the vaporizing humidifier of the present invention combines the water inlet and the upper coating of the motor, the opening of the water inlet can be widely formed in the vicinity of the center of the upper portion of the humidifier, and the opening of the water inlet is formed larger. Thus, there is an advantage that water can be easily supplied to the water storage container.

  Next, the flow of air flowing through the humidifier and the mechanism by which the flowing air is humidified will be described with reference to FIG. Thick arrows in FIG. 7 indicate the flow of air.

  First, when a power switch provided on the lower outer shell 12 is pressed to turn on the power, the motor 36 rotates and the blower fan 34 rotates. When the blower fan 34 rotates, the air inside the humidifying filter 22 is sucked by the blower fan 34 and the space inside the humidifying filter 22 is decompressed.

  When the space inside the humidifying filter 22 is decompressed, the air in the space outside the humidifying filter 22 is sucked into the space inside the humidifying filter 22 and the space outside the humidifying filter 22 is decompressed. When the space outside the humidification filter 22 is depressurized, external air is sucked into the lower outer shell 12 through the air inlet 14. External air that has entered the inside of the lower outer shell 12 passes through the enzyme filter 26 and enters the space outside the humidifying filter 22. The outside air is sterilized by the enzyme added to the enzyme filter.

  External air that has entered the space outside the humidifying filter 22 passes through the humidifying filter 22 and enters the inside of the humidifying filter 22. When water is contained in the water storage container 16, the humidification filter 22 is moistened by the water in the water storage container 16, so that the external air is humidified by the humidification filter 22 and the humidity becomes high.

  Air that has entered the humidification filter 22 and has increased in humidity is sucked by the blower fan 34 and is discharged toward the space between the upper partition wall 30 and the upper cover 42, and along the upper partition wall 30 and the upper outer shell 52. It reaches the exhaust port 56 and is discharged upward from the exhaust port 56.

  Next, the procedure for pouring water into the water inlet of the humidifier and the flow of the poured water will be described with reference to FIGS. 4 and 5. To do. The thick arrows in FIG. 4 indicate the flow of water.

  First, the amount of water in the water storage container 16 is obtained by a weight sensor and a control device on the inner bottom of the humidifier 10 and displayed on the display unit 40. The person who manages the humidifier 10 looks at the amount of water displayed on the display unit 40 and determines whether or not it is necessary to replenish water.

  When it is determined that it is necessary to supply water to the humidifier 10, water is drawn into a container such as a kettle, and water is poured from above the humidifier 10 toward the water inlet 48, that is, the upper coating 42. Since the diameter of the water injection port 48 is considerably larger than the diameter of the water injection port of the conventional humidifier, water can be poured easily without spilling around.

  The water poured onto the water inlet 48, that is, the upper coating 42 flows toward the peripheral side on the surface of the upper coating 42 and collects in the peripheral ridge 44. The water collected in the peripheral gutter 44 flows into the water channel 32 formed between the lower partition wall 28 and the upper partition wall 30 through the plurality of crossing channels 50, flows down the water channel 32, and enters the water storage container 16.

  Since the amount of water in the water storage container 16 is displayed on the display unit 40, water injection is continued while observing the amount of water displayed on the display unit 40, and when the display unit 40 displays full water or at an appropriate amount of water, stop. Even if the amount of water displayed on the display unit 40 is overlooked, the speaker emits an alarm sound when the water storage container 16 is full. Therefore, the water injection can be stopped safely when the alarm sound is generated.

  The present invention can also be applied to a humidifier that evaporates water using a heater or an application that pours water into a water storage container of a humidifier that atomizes water using ultrasonic waves.
