Abstract

The invention belongs to the technical field of household appliances, and discloses a method for eliminating water dripping sound of a high-capacity evaporation type humidifier. When the high-capacity evaporative humidifier operates, water sprayed on the wet film cannot be completely evaporated, and the residual water flows back to the water tank through the drain hole of the wet film basket and drops on the liquid level of the water tank of the humidifier, so that dripping sounds of a grommet and a swooshing are generated. The invention changes the drain hole of the wet film basket of the humidifier into a drain pipe protruding to the water tank of the humidifier. The drain pipe is connected with a water pipe. The water pipe is made of plastic or rubber. One end of the water pipe is connected with the water drain pipe, the other end is hung in the humidifier water tank. The water pipe directly conveys the water flowing out of the wet film basket to the position below the liquid level of the water tank of the humidifier. Thus, the water dripping sound generated when the high-capacity evaporative humidifier operates is eliminated. The noise of the high-capacity evaporative humidifier in the night mode operation is reduced by 10.2 dB.

Description

Method for eliminating water dripping sound of high-capacity evaporation type humidifier The invention belongs to the technical field of household appliances. Is a technical solution for eliminating the water dripping sound of the high-capacity evaporative humidifier. The prior art comprises the following steps: In the existing common evaporative humidifier, the capacity of a water tank is generally 3-6 liters. In northeast China, the long winter time is as long as 5-6 months, and the indoor air humidity is only about 20%. To raise the air humidity to around 50% in a 100 square meter room, the humidifier needs to evaporate 12-16 liters of water per day. Therefore, the evaporative humidifier with common capacity needs to add water to the water tank 2-4 times per day in time. This is indeed somewhat cumbersome for the user. To reduce the trouble, only the capacity of the evaporative humidifier water tank can be increased. Therefore, a large capacity (meaning a water tank capacity of more than 10 liters) evaporative humidifier has been developed. In the use process of the high-capacity evaporative humidifier (hereinafter referred to as humidifier), water needs to be added into a water tank positioned at the bottom of the humidifier, and the water of the humidifier is sent to the upper part of the humidifier through a water pump of the humidifier. At the upper part of the humidifier, there is a device with wet film, which can be called a wet film basket. The upper part of the wet film basket is provided with a circular water tank, and the bottom of the circular water tank is provided with a plurality of small holes. The water pump of the humidifier sends the water of the water tank into the annular water tank, and the water in the water tank is sprayed on the wet film below the water tank through the small holes at the bottom of the water tank. The wind generated by the fan of the humidifier blows through the wet film of the humidifier, so that the moisture on the wet film is evaporated. The fan discharges the humidified air into the room through the air outlet of the humidifier, thereby improving the indoor air humidity. The water sprayed on the wet film does not evaporate completely. The rest water flows back into the humidifier water tank through the drain hole at the bottom of the wet film basket. As the moisture sprayed on the wet film evaporates continuously, the level of the humidifier water tank decreases gradually. The distance between the drain hole of the wet film basket and the liquid level of the water tank is correspondingly increased gradually. Water flowing out of the drain hole of the wet film basket of the humidifier drips onto the liquid level of the water tank of the humidifier, and then the dripping sound of the beeping and the beeping is generated. As the level of the humidifier water tank gradually decreases, the water dripping sounds of the swooshing and swooshing increase accordingly. When the humidifier is operated with high power, the sound generated by the exhaust fan can reach 69 db. To mitigate indoor noise, many users often employ a night mode of the humidifier. At this time, the humidifier runs at low power, and the noise generated by the exhaust fan is relatively small. The dripping sounds of the humidifier beeps and beeps become apparent. The decibel detector is used for detection, and the dripping sound of the humidifier can reach about 55 decibels. At night, 55 db of noise is sufficient to affect a person's sleep. The invention aims to eliminate dripping sounds of a scuba and a beep generated when a humidifier operates. The technical proposal of the invention is that a water pipe is linked at the drain hole of the wet film basket, and the water flowing out of the drain hole of the wet film basket is directly conveyed below the liquid level of the water tank of the humidifier. In order to be convenient for linking with the water delivery pipe, the humidifier drain hole can be designed at the center of the bottom of the wet film basket and is in a circular tube shape protruding towards the water tank. I.e. the drain hole is modified to be a drain. The outer diameter of the far end of the drain pipe (the link end of the water delivery pipe) is slightly smaller than that of the near end. The inner diameter of the drain pipe is 4-8MM, the length is about 15MM, and the structure is shown in the attached drawing. The water pipe is made of plastic or rubber hose. The inner diameter is slightly smaller than the outer diameter of the drain pipe. The length of the water delivery pipe is 2-3CM from the water discharge hole to the bottom of the humidifier water tank (when the water level of the humidifier water tank is lower than 3CM, the humidifier can automatically stop). One end of the water pipe is sleeved outside the water pipe and fixed by the elasticity of the plastic pipe or the rubber pipe. The other end is hung in the water tank.
