Description

Technical Field

[0001] The present invention relates to the field of humidifiers, and in particular to a low-power consumption and high-efficiency evaporation device and method for a pure humidifier. Background Art

[0002] There are many types of existing humidifiers, such as ultrasonic atomizing humidifiers and electric heating humidifiers. Although the ultimate goal of various humidifiers is to increase the humidity of indoor air, they have different advantages and disadvantages. Some humidifiers have a low humidification rate per unit volume, some humidifiers consume a lot of electricity when vaporizing water, and some humidifiers have a limited amount of humidification per unit power consumption; for example, electric heating humidifiers have high safety performance requirements, and ultrasonic atomizing humidifiers have high water quality requirements. The most suitable humidifier for the market is the natural evaporation type humidifier, which mainly evaporates water naturally through an evaporation device, and the fan flows the moisture to the outside to achieve humidification.

[0003] Existing evaporation devices are all immersed below the water surface of the water tank. As the evaporation device rotates, a water film is formed. The airflow transported by the fan contacts the water film to form moisture. Since moisture is output to the outside with the airflow, an important factor in increasing the humidification amount is to increase the airflow, so that more moisture can be transported to the outside in a unit time. However, increasing the airflow will inevitably increase the fan load, resulting in increased energy consumption and even noise. Therefore, it is worth studying how to reduce the fan power while ensuring humidification efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a low-power and high-efficiency evaporation device and method for a pure humidifier, in the hope of optimizing the existing humidifier to increase the humidification capacity, which may lead to excessive fan energy consumption and even noise problems.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A low-power consumption and high-efficiency evaporation device for a pure humidifier comprises an evaporator for being placed in a water tank, the evaporator comprising a driving shaft, a plurality of evaporation sheets being mounted on the driving shaft, a metal sheet being arranged inside the evaporation sheet, an electromagnetic inductor corresponding to the metal sheet being arranged on one side of the evaporator, the electromagnetic inductor and the metal sheet forming an eddy current magnetic field, the metal sheet being used to correspond to the electromagnetic inductor at least once during the rotation of the evaporator, and the electromagnetic inductor being electromagnetically induced by the metal sheet when the evaporator rotates to increase the temperature of the evaporation sheet.

[0007] Preferably, the electromagnetic inductor is placed at the upper opening of the water tank, the upper end of the evaporation sheet is higher than the upper opening of the water tank, and when the metal sheet is matched with the electromagnetic inductor, the height of the metal sheet is higher than the upper opening of the water tank.

[0008] A further technical solution is that the transverse length of the electromagnetic inductor is equal to or greater than the axial width of the evaporator, and the electromagnetic inductor heats the metal sheets on the multiple evaporating sheets simultaneously.

[0009] Preferably, a limiting portion is provided on the driving shaft, and a clamping portion corresponding to the limiting portion is provided on the inner ring of the evaporation plate, and the evaporation plate is fixed on the driving shaft by the clamping portion.

[0010] Preferably, the evaporation sheet is provided with water film holes, and the metal sheet radiates heat energy to the water film holes through the insulating layer.

[0011] A further technical solution is that bosses are provided on the surface of the evaporation sheet, and the bosses between two adjacent evaporation sheets contact each other, so that there are gaps between the evaporation sheets that are sufficient for air circulation.

[0012] A further technical solution is that there are multiple metal sheets inside the evaporating sheet, and the metal sheets are evenly distributed around the evaporating sheet, and the electromagnetic inductor heats up different metal sheets in turn.

[0013] Preferably, the electromagnetic inductor comprises a shell, an electromagnetic coil is arranged inside the shell, an eddy current magnetic field is formed near the metal sheet by the electromagnetic coil, and reinforcing ribs are arranged on the evaporation sheet.

[0014] The present invention also discloses a low-power and high-efficiency evaporation method for a pure humidifier. When a water film is formed on the evaporator, an electromagnetic inductor and a metal sheet inside the evaporating plate form an eddy current magnetic field, thereby increasing the temperature of the internal metal sheet; the evaporating plate is heated as a whole, thereby heating the water film and causing the water film to evaporate.

[0015] Preferably, the following steps are also included: step A, injecting water into the water tank, and the minimum liquid level height needs to immerse the lower part of the evaporator; step B, the evaporator is driven by the drive shaft to rotate as a whole, and the evaporator takes the water away from the liquid surface, at which time a water film is formed on the evaporation plate of the evaporator; step C, starting the electromagnetic inductor to heat up the evaporator as a whole and evaporate the water film; step D, starting the fan to generate a continuous airflow, and the airflow passes through the evaporator to promote the evaporation of the water film.

[0016] Compared with the prior art, the beneficial effects of the present invention are at least one of the following:

[0017] The present invention generates heat energy by the evaporator itself, increases the water volatilization rate, and improves the humidification efficiency of the humidifier under the same wind speed. Similarly, under the same humidification amount, the fan speed and energy consumption can be reduced, which helps to improve the silent efficiency of the humidifier and reduce power consumption.

[0018] The present invention forms eddy currents on a metal sheet through an electromagnetic inductor, so that the metal sheet generates heat, and the heat acts on a water film formed on an evaporation sheet, so that the moisture content in the air flow is increased.

[0019] The invention prevents the electromagnetic inductor from being soaked by evaporating water by setting the height of the electromagnetic inductor, thereby ensuring the safety of the working components inside the electromagnetic inductor.

[0020] The present invention heats the metal sheets on a plurality of evaporating sheets by an electromagnetic inductor, thereby reducing the wiring difficulty of the humidifier and facilitating the heating of the evaporator as a whole.

[0021] The present invention enables a plurality of evaporation sheets to be sleeved on a driving shaft by pairing a limiting portion and a clamping portion, and increases the amount of water film on the evaporation sheet through the water film holes, making it easier for the water film to be formed on the evaporation sheet, and controlling the thickness of the water film. The thickness of the water film holes attached to the evaporation sheet is controlled at the micron level, so that when the water film on the water film holes is heated, it can evaporate instantly, thereby achieving a good evaporation effect with low energy consumption.

[0022] The present invention ensures that the evaporating plates have sufficient air gaps after installation through the bosses, thereby ensuring that air can flow normally between the two evaporating plates.

[0023] The present invention has multiple metal sheets, so that according to the heating area requirements, the heat can be concentrated in the local area during the rotation of the evaporating sheet, effectively reducing the heat energy of the metal sheet acting on the water surface in the water tank under the action of thermal bridge.

[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] Embodiment 1:

[0035] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of the present invention is a low-power consumption and high-efficiency evaporation device for a pure humidifier, comprising an evaporator 2 for placement in a water tank 1, the evaporator 2 comprising a drive shaft 3, a plurality of evaporation sheets 4 mounted on the drive shaft 3, the evaporation sheets being made of heat-resistant plastic material, such as PVC plastic. The lower end of the evaporator 2 is immersed in the water tank 1, and the evaporation sheets 4 are driven by the drive shaft 3 to rotate, thereby forming natural evaporation conditions, and then the humidifier fan cooperates to work together to achieve air humidification.

[0036] A metal sheet 5 is provided inside the evaporator sheet 4, and an electromagnetic inductor 7 corresponding to the metal sheet 5 is provided on one side of the evaporator 2. The electromagnetic inductor 7 and the metal sheet 5 form an eddy current magnetic field. By placing the metal sheet 5 in the alternating magnetic field of the electromagnetic inductor 7, eddy currents are generated near the metal sheet 5, and the eddy current phenomenon can heat up the metal sheet 5.

[0037] The metal sheet 5 is used to correspond to the electromagnetic inductor 7 at least once during the rotation of the evaporator 2, and the electromagnetic inductor 7 electromagnetically induces the metal sheet 5 when the evaporator 2 rotates and increases the temperature of the evaporation sheet 4, wherein the metal sheet 5 is wrapped in the evaporation sheet 4, and the metal sheet 5 is installed in the evaporation sheet 4 in various forms:

[0038] For example, when the metal sheet 5 is a single sheet, the metal sheet 5 is coaxially arranged with the evaporation sheet 4, and the size of the metal sheet 5 matches the size of the evaporation sheet 4. When the evaporation sheet 4 rotates, a part of the metal sheet 5 continuously corresponds to the electromagnetic inductor 7, thereby realizing continuous heating of the evaporation sheet 4.

[0039] For example, when there are multiple metal sheets 5, the metal sheets 5 are distributed in multiple areas of the evaporator sheet 4, and the metal sheets 5 are distributed in a ring array on the evaporator sheet 4 to ensure that when the evaporator sheet 4 rotates, different metal sheets 5 correspond to the electromagnetic inductor 7 at least once. The ring distribution ensures that when the metal sheets 5 correspond to the electromagnetic inductor 7, the temperatures of the metal sheets 5 are relatively close, thereby ensuring the uniformity of the overall heating of the evaporator sheet 4.

[0040] It should be noted that, according to the volume of the humidifier and the humidification specifications, metal sheets 5 with different resistivities are selected, and the heating efficiency of the metal sheet 5 is controlled by the resistivity. At the same time, it is also necessary to adjust the number of turns of the coil in the electromagnetic inductor 7 based on the thermal energy demand to constrain the temperature of the metal sheet 5, and its current ratio is equal to the inverse ratio of the turns ratio, that is, under the condition of constant magnetic flux density, the larger the area of ​​the metal sheet 5 orthogonal to the magnetic field vector, the higher the heating efficiency of the metal sheet 5. As a result, the magnetic flux cutting area of ​​the metal sheet 5 is relatively small to avoid high temperature.

[0041] Embodiment 2:

[0042] Based on the above embodiments, reference Figure 5 As shown, another embodiment of the present invention is that the electromagnetic inductor 7 is placed at the upper opening of the water tank 1, so as to prevent the pure water in the water tank 1 from splashing onto the electromagnetic inductor 7 during the rotation of the evaporator 2, that is, the electromagnetic inductor 7 has a better waterproof effect under the same waterproof level.

[0043] The height of the upper end of the evaporation sheet 4 exceeds the upper opening of the water tank 1. When the metal sheet 5 is matched with the electromagnetic inductor 7, the height of the metal sheet 5 exceeds the upper opening of the water tank 1. On the one hand, the upper end of the evaporation sheet 4 exceeds the maximum liquid level of the water level in the water tank 1, which is easy to volatilize. On the other hand, the upper end of the evaporation sheet 4 is closer to the electromagnetic inductor 7, so it is easy for the electromagnetic inductor 7 to generate eddy currents on the evaporation sheet 4. It should be noted that the electromagnetic radiation generated by the electromagnetic induction heating realized by the eddy current is lower than the electromagnetic radiation when the mobile phone is turned on, so it will not cause harm to the human body and can be fully applicable to the humidifier.

[0044] For further reference, Figure 6 As shown, the transverse length of the electromagnetic inductor 7 is equal to or greater than the axial width of the evaporator 2, and the electromagnetic inductor 7 heats the metal sheets 5 on the multiple evaporation sheets 4 at the same time. Due to the transverse length of the electromagnetic inductor 7, one electromagnetic inductor 7 can act on the multiple evaporation sheets 4 provided by the evaporator 2, thereby ensuring that the water film of the entire evaporator 2 has a certain amount of thermal energy, achieving a larger scale of evaporation efficiency, and improving the overall humidification effect of the humidifier.

[0045] Embodiment 3:

[0046] Based on the above embodiments, refer to Figure 6As shown, another embodiment of the present invention is that the driving shaft 3 is provided with a limiting portion 301, and the inner ring of the evaporation sheet 4 is provided with a clamping portion 401 corresponding to the limiting portion 301, and the evaporation sheet 4 is fixed to the driving shaft 3 by the clamping portion 401. The limiting portion 301 is an existing mounting hole on the driving shaft 3, and the clamping portion 401 is an existing buckle mechanism that matches the limiting portion 301, and the evaporation sheet 4 is fixed to the driving shaft 3 by inserting the clamping portion 401 into the limiting portion 301.

[0047] Embodiment 4:

[0048] Based on the above embodiments, refer to Figure 7 As shown, another embodiment of the present invention is that the evaporation sheet 4 is provided with a water film hole 402, and the metal sheet 5 dissipates heat energy to the water film hole 402 through the insulating layer 6, wherein the water film hole 402 adopts a through hole structure, and an inverted cone-shaped mouth is provided around the through hole, and the water film formed by the water film hole 402 is a micron-sized water film, so that a large number of micron-sized water films are distributed on the evaporation sheet 4, and the micron-sized water film can be instantly heated under the action of the metal sheet 5, so that the water film can evaporate faster with extremely low energy consumption, which is helpful to improve the overall humidification effect of the humidifier.

[0049] Furthermore, in order to ensure the stability of the evaporation sheet 4 during the rotation process, the surface of the evaporation sheet 4 is provided with a boss 403, and the bosses 403 between two adjacent evaporation sheets 4 collide with each other, so that there is a gap between the evaporation sheets 4 for sufficient air circulation. Since the diameter of the evaporation sheet 4 may be relatively large, the outer side of the evaporation sheet 4 may vibrate due to gravity during the rotation process. In order to prevent the outer contour of the evaporation sheet 4 from vibrating during the operation process and affecting the stability of the airflow channel of the evaporation sheet 4, the bosses 403 of different evaporation sheets 4 collide with each other, thereby ensuring that there is a gap between the evaporation sheets 4 for sufficient air circulation.

[0050] Furthermore, there are multiple metal sheets 5 inside the evaporation sheet 4, and the metal sheets 5 are evenly distributed around the evaporation sheet 4, and the electromagnetic inductor 7 heats up different metal sheets 5 in sequence. Since the evaporation sheet 4 rotates when the evaporator 2 is working, if the metal sheets 5 are unevenly distributed on the evaporation sheet 4, centrifugal force may occur during the rotation of the evaporation sheet 4, increasing the supporting pressure of the boss 403. Therefore, when multiple metal sheets 5 are used, the metal sheets 5 need to be evenly distributed around the evaporation sheet 4, and the metal sheets 5 locally heat the evaporation sheet 4, so that the local water film holes 402 can be heated to ensure the stable evaporation of pure water.

[0051] Embodiment 5:

[0052] Based on the above embodiment, another embodiment of the present invention is that the electromagnetic inductor 7 includes a shell 701 , the lower end of the shell 701 is a working surface, an electromagnetic coil is arranged inside the shell 701 , and an eddy current magnetic field is formed near the metal sheet 5 by the electromagnetic coil.

[0053] Among them, the electromagnetic inductor 7 outputs low-frequency electromagnetic waves, that is, using an alternating magnetic field to generate a large number of eddy currents. Since low-frequency electromagnetic waves can penetrate non-metallic objects, the material of the working surface can be plastic. The electromagnetic waves emitted by the electromagnetic inductor 7 can pass through the working surface of the shell 701 and directly act on the metal sheet 5.

[0054] It should be noted that, although low-frequency electromagnetic waves are relatively safe, in order to ensure that the low-frequency electromagnetic waves only act on the metal sheet 5 on the evaporation sheet 4, the shell 701 and the upper end thereof may be provided with an anti-interference shield. Specifically, the shell 701 and the upper end thereof may be provided with an additional aluminum sheet inside the plastic shell, and the aluminum sheet needs to be grounded, thereby forming a closed metal box body with good grounding, so as to prevent the electromagnetic waves emitted by it from interfering with the outside, or to prevent the normal operation from being disturbed by external electromagnetic wave noise.

[0055] The evaporation sheet 4 is provided with reinforcing ribs 8 , which improve the load-bearing strength of the evaporation sheet 4 , thereby improving the supporting force of the evaporation sheet 4 on the metal sheet 5 , and preventing the evaporation surface of the evaporation sheet 4 from bending.

[0056] Embodiment 6:

[0057] Based on the above embodiments, another embodiment of the present invention is a low-power and high-efficiency evaporation method for a pure humidifier, which forms a water film on the evaporator 2, starts the electromagnetic inductor 7, and forms an eddy current magnetic field between the electromagnetic inductor 7 and the metal sheet 5 inside the evaporation sheet, thereby increasing the temperature of the internal metal sheet 5; the evaporation sheet 4 is heated as a whole, thereby heating the water film and evaporating the water film.

[0058] Furthermore, the following steps are included: Step A, injecting water into the water tank 1 , and the minimum liquid level height needs to immerse the lower part of the evaporator 2 .

[0059] Since the device is used in an existing evaporative humidifier, and the existing evaporative humidifier is usually equipped with a fan, air is supplied by the fan to ensure controllable humidification efficiency, in order to ensure that the water used for humidification is relatively healthy, the water used in the evaporator 2 can be pure water.

[0060] In step B, the driving shaft 3 drives the evaporator 2 to rotate as a whole, and the evaporator 2 takes the water away from the liquid surface. At this time, a water film is formed on the evaporation sheet 4 of the evaporator 2.

[0061] The drive shaft 3 is connected to the motor through the existing gear mechanism, and the motor drives the drive shaft 3 to work, so that when the evaporation sheet 4 rotates, the tension of the pure water itself can be used to form a water film in the process of lifting the evaporation sheet 4 of the evaporator 2 from the water surface. The rotation of the drive shaft 3 drives the entire evaporator 2 to rotate, that is, to ensure that multiple evaporation sheets 4 can work synchronously.

[0062] Step C, start the electromagnetic inductor 7 to heat up the evaporator 2 as a whole and evaporate the water film. For the efficiency of the equipment, this operation is usually carried out under the premise of ensuring that the pure water immerses the evaporator and the fan delivers air normally, and then start the electromagnetic inductor to heat the metal sheet.

[0063] Step D, start the fan to generate a continuous airflow, which passes through the evaporator 2 to promote the evaporation of the water film. After the water film is formed and the electromagnetic inductor 7 has heated the water film, the fan drives the airflow to pass through the water film. By the constant air supply of the fan, the temperature and air flow can be used to jointly affect the humidification efficiency while the energy consumption of the fan is relatively low.

[0064] Taking into account the usual safety regulations, if humidification is stopped, on the premise of ensuring that the pure water immerses the evaporator 2 and the fan is supplying air normally, first turn off the electromagnetic sensor 7, then stop the fan supplying air, and finally stop the rotation of the evaporator 2 to ensure that the heat of the evaporator 2 is discharged as much as possible when humidification is stopped.

[0065] It should be noted that when the level of pure water in the water tank 1 is lower than the lower end of the evaporation sheet 4, humidification usually needs to be stopped to avoid the failure to form a water film on the evaporator 2, resulting in low moisture content in the airflow, which may affect the indoor humidification effect. Therefore, if necessary, the liquid level detection unit in the water tank 1 can be connected to the electromagnetic sensor 7 and the control unit signal of the fan to ensure that the electromagnetic sensor 7 and the fan can stop working automatically after the liquid level is lower than the set range.
