Description

Technical Field

[0001] The invention relates to the field of air humidification, and in particular to a humidifier based on an atomizer to control water flow rate. Background Art

[0002] Pure heating humidifiers use the method of boiling water to humidify, which can achieve the purpose of boiling sterilization, but what comes out is steam, which has the defects of high energy consumption, high noise, unsafe high mist outlet temperature, and slow mist outlet speed.

[0003] Pure ultrasonic humidifiers, the water mist coming out will bring out the scale in the water, causing "white powder pollution".

[0004] The hybrid humidifiers currently available on the market are humidifiers that have both a heater and an ultrasonic atomizer installed in the machine. The problem with this type of humidifier is that after the heater heats the water to achieve a sterilization effect, the ultrasonic atomizer is not suitable for normal operation at too high a temperature, and the hot water will affect the service life of the ultrasonic atomizer. The existing technologies have the following solutions to this problem:

[0005] 1. Set the power of the heater to a relatively low level so that the water temperature will not be too high (above 60 degrees);

[0006] 2. The water flowing out of the water tank flows into the heating water tank and the atomizing water tank through two channels respectively, so that the water temperature at the atomizing piece will not be too high.

[0007] The disadvantage of these two solutions is that the water used for ultrasonic atomization has not been boiled and cannot achieve a full sterilization effect.

[0008] JP1994331186A proposes a humidifier. When the switch is turned on, the built-in tubular heater 34 in the connecting pipe 23 is energized, the water in the pipe is heated and boiled, and flows from the highest part of the connecting pipe 35 to the downstream to the cooling water tank 24. On the way, it is cooled to a specified temperature below 50°C through the cooling pipe 38, and flows into the second water storage tank 22. The water flowing into the second water storage tank 22 is heated to a high temperature and sterilized in the process of passing through the tubular heater 34. At this time, magnesium, potassium, etc. in the water are precipitated and removed in the tubular heater 34 to prevent white powder from adhering to furniture, etc. The heated water is cooled to a predetermined temperature, which can prevent heat loss of the components of the ultrasonic unit 5. However, the humidifier structure of this scheme is unreasonable, the swirling pipes make the humidifier bulky, and the scale precipitated inside the pipes after heating cannot be cleaned.

[0009] KR200170374Y1 proposes another humidifier, in which a heater element installed in a sterilization tank 30 works to heat the water therein to a predetermined temperature. The heated water flows along a cochlear cooling channel 31 connected to a humidification tank 40, and is cooled to a specified temperature (about 40 degrees or less) by the wind of a blower and supplied to a humidification tank 40. The water in the humidification tank 40 is converted into fine particles by a vibration device 41. KR200170374Y1 supplies the water cooled by the blower to the humidification tank by bypassing the water by a predetermined distance, and can also prevent thermal damage to the vibration device. However, there is also the problem of a lengthy cooling channel. Although it cleverly surrounds the channel around the humidification tank to achieve miniaturization, it does not utilize the idea of ​​a vibration device. Summary of the invention

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] See also Figure 1 to Figure 2 The humidifier consists of a water tank 100 and a base 200. The water tank 100 is provided with a water outlet 101. The top surface of the base 200 is sunken to form a lower water tank 210, a first water storage tank 220, a cooling water tank 230, and a second water storage tank 240. Each water tank is exposed from the top surface of the base 200.

[0040] The lower water tank 210 is connected to the first water storage tank 220. The lower water tank 210 has a built-in water outlet control device, which is used to control the opening and closing of the water outlet so that the water in the water tank 100 can enter the first water storage tank 220 to maintain a stable water level. The first water storage tank 220 is equipped with a heater 221, which is installed at the bottom of the tank using a heating plate.

[0041] The cooling water tank 230 is connected to the first water storage tank 220 and the second water storage tank 240 respectively. The water tank 230 is equipped with a cooling device. The cooling device uses the water in the water tank 100 to cool the water flowing through the cooling water tank 230 and / or uses the wind blown by the fan 300 to cool the water flowing through the cooling water tank 230. The atomizer 241 is installed in the first water storage tank 220 as a control component of the flow speed of the water in the cooling water tank 230. Its atomization efficiency is configured to make the flow speed low enough so that the cooling device can cool the water temperature flowing into the second water storage tank 240 to a temperature below the safety of the atomizer 241.

[0042] A mist outlet channel 400 is disposed directly above the second water storage tank 240 , and the fan 300 is used to drive the water mist generated by the atomizer 241 to be discharged from the humidifier through the mist outlet channel 400 .

[0043] For a humidifier, the water in the water tank 100 occupies the largest volume of the space inside its shell. The water mist needs to be discharged, which necessarily requires a fan 300. The solution of the present invention uses the water in the existing water tank 100 for water cooling and the wind from the existing fan 300 for air cooling. No additional cooling source is needed, but a better cooling effect can be achieved. The existing atomizer 241 itself is used as a control component for the water flow rate in the cooling water tank 230. By controlling the decrease in the flow rate, the limitation of the cooling channel length is removed in disguise. Combined with the cooling effect achieved above, the humidifier can be miniaturized and compact in structure. The water atomized by the atomizer 241 is boiled and softened to avoid health problems caused by white powder pollution. After boiling, the water is cooled and fed to the atomizer to avoid thermal damage.

[0044] As a solution for controlling the water flow rate of the atomizer 241, the structures of the first water tank 220, the second water tank 240, and the cooling water tank 230 are configured so that the water level A of each tank is kept at the same height relative to the same reference plane when the atomizer 241 is working normally. At this time, the atomizer 241 is the only water-consuming device, and its atomization drives the water flow to flow along the first water tank 220, the cooling water tank 230, and the second water tank 240 at a slow speed. The water outlet control device controls the replenishment of water in the first water tank 220 to maintain the stability of the water level line. This method makes full use of the existing components of the humidifier, and no additional devices are required to avoid expanding the volume. On this basis, further, a drain valve 222 is set to control the water in the first water tank 220 to enter the cooling water tank 230. The design of the drain valve 222 can prevent unheated water from directly flowing into the water tank 240, which makes it difficult to sterilize in the initial stage and white powder floats in the air. Furthermore, the water level of the atomizer 241 under normal working conditions is set higher than the valve port of the drain valve 222 and the left and right water ports 231 of the cooling water tank 230, and the water surface fluctuations of the three water tanks are isolated to prevent the boiling of the heated liquid surface in the water storage tank 220 and / or the wind blowing the liquid surface in the cooling water tank 230 from affecting the control of the water flow rate by the water storage tank 240. In the above, in order to form an effective heat partition, the water outlet cross-sectional area of ​​the water outlet channel of the first water storage tank 220 to replenish water to the cooling water tank 230 is no more than 1000 square millimeters. In the case of a drain valve 222, the valve port of the drain valve 222 is set as the control of the water outlet channel.

[0045] As another solution for realizing that the atomizer 241 controls the water flow rate, the water level is not necessarily completely consistent. For example, a water supply control device is provided to replenish a corresponding amount of water from the first water storage tank 220 to the cooling water tank 230 according to the amount of water atomized by the atomizer 241 per unit time, and an inlet and outlet balance is formed through electrical control. For example, the water discharge valve 222 adopts an electromagnetic opening valve, and the water discharge valve 222 is used as the water supply control device, and the water level in the water storage tank 220 is allowed to be higher than that in other water tanks.

[0046] In the above, the atomization efficiency of the atomizer 241 is configured to produce at most 1000 ml of water mist per hour to form a low-speed flow of water to cooperate with the cooling device for cooling. In the above configuration, it is allowed to set the cooling water tank 230 between the first water storage tank 220 and the second water storage tank 240. The three water tanks form a linear distribution structure. The humidifier has a compact structure and can leave more space for the water tank. The increase in the upper limit of the water capacity of the water tank in turn enhances the water cooling effect. Preferably, the atomizer 241 uses an ultrasonic vibrator to achieve the refinement of the water mist particles.

[0047] A specific implementation example of the cooling device is given below.

[0048] As a water cooling implementation, the cooling device includes a heat sink 232 with heat transfer performance. The heat sink 232 can be of any shape and contacts the water in the water tank 100 and the cooling water tank 230 respectively as a heat exchange component. Figure 3a to Figure 3b An independent water cooling solution with the aid of water tank cooling is provided. The air outlet of the fan 300 is not arranged in the cooling water tank 230. The cooling of the hot water is mainly achieved by heat exchange of the radiator 232. The air outlet is arranged outside the cooling water tank 230 and does not participate in the cooling of the hot water.

[0049] or, Figure 4a to Figure 4b A mixed air-cooling and water-cooling solution is provided. In addition to cooling the hot water through heat exchange of the heat sink 232, the air outlet 301 of the fan 300 is arranged outside the cooling water tank 230. The wind blows through the outer side of the heat sink 232 and the water surface in the cooling water tank 230 to cool the hot water.

[0050] Most preferably, see Figure 1 to Figure 2 The heat sink 232 has a built-in cavity. One end of the heat sink 232 extends into the water tank 100, and the other end extends into the cooling water tank 230. The side wall of the cooling water tank is provided with a water outlet 231, which is connected to the first water storage tank 220 and the second water storage tank 240 respectively. The water outlet 231 is lower than the water level of the atomizer 241 under normal working conditions. The air outlet of the fan 300 extends into the inner cavity of the heat sink 232, and the inner cavity opening of the heat sink 232 is connected to the mist outlet channel 400 through the air passage 233. When in use, the water in the water tank flows into the lower water tank of the base through the water tank outlet, and the lower water tank is connected to the heating water tank. After the water in the heating water tank is boiled by the heater, the water valve is opened, and the boiling water flows into the cooling water tank. The heat sink is installed at the bottom of the water tank, and is made of heat-conducting material. One end is in contact with the cold water in the water tank, and the other end is in contact with the hot water in the cooling water tank. The hot water is cooled by heat exchange. At the air outlet inside the heat sink, the wind blown by the fan is concentrated on the heat sink and the surface of the hot water, achieving the optimal purpose of accelerating the cooling of the hot water, reducing the wind noise effect, and at the same time the structure is the most compact. After the hot water is cooled, it flows into the atomization tank for atomization, and then is blown out of the machine by the wind. It should be understood that in addition to cooling with the help of the water in the water tank, an independent air cooling scheme can be set up, and the water in the water tank does not participate in the cooling. For example, a heat sink is not set up to directly guide the wind from the fan to the water surface, or the heat sink is not set up as a heat exchanger with the water in the water tank, and the wind from the fan is guided to the outer wall of the heat sink, and the heat sink is only used as a component to accelerate the air cooling effect.

[0051] Furthermore, a steam channel is provided, and the steam channel is connected to the first water storage tank 220 and the mist outlet channel 400 respectively. The provision of the steam channel not only solves the steam emission generated during heating and sterilization, but also increases the mist output of the machine, achieving the effect of killing two birds with one stone. Among them, the steam can be spontaneously discharged with the help of its own heat. Preferably, a fan 300 is used as a multiplexing device for the driving device of water mist emission and the driving device of steam emission. The wind from the fan is finally blown to the mist outlet channel to form a negative pressure, pulling the water mist and steam to be discharged, and increasing the mist outlet speed. Figure 5 A schematic diagram of the flow direction of the fan discharge through the air passage of the cooling water trough is given. As the most preferred embodiment, the heating water trough, the cooling water trough, and the atomizing water trough can be connected above to form a channel, wherein the steam channel is configured to have at least some sections using the heat sink 232 as at least a part of the channel side wall. The steam generated during heating passes through the channel and mixes with the atomized water vapor and is discharged out of the machine. The flow direction of the steam is shown by the arrow in the figure. When the steam flows through, it contacts the heat sink 232 to cool down, and then enters the top of the water storage tank 240 to mix with the water mist for a second cooling. The mist outlet temperature is safe and controllable.

[0052] As another improvement, the base 200 for accommodating each water tank is located below the water tank 100, forming an upper water-adding type. At this time, the water outlet control device can be set as a float valve, which is opened to replenish the water level as the water in the water storage tank 220 is consumed. Further, each water tank is exposed on the top surface of the base, and the water tank 100 can be detachably placed on the base. The water tank 100 serves as a covering component of the water tank. When necessary, the water tank is taken out, and the exposed water tank is convenient for cleaning scale. Alternatively, the water outlet control device is a water pump, which replenishes the corresponding amount of water into the water storage tank 220 according to the amount of atomized water per unit time of the atomizer 241. At this time, the water tank can be located above or below the base, and water is pumped by the water pump. When the water tank is located below, the base is on top, and each water tank is exposed on the top surface of the base. A detachable cover is set on the top surface of the base. The cover serves as a covering component of the water tank and is opened when it needs to be cleaned.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
