Description

Humidifying device

Technical field

The present invention relates to a humidifier to humidify air to be supplied, for example, to a room, and in particular, to a humidifier to humidify air to be supplied collecting moisture from the air not having No water supply unit planned.

Background of the invention

There is conventionally a humidifier of this type, corresponding to the preamble of claim 1, as It is represented in Figure 5 (Japanese Patent Published HEI Number 8-141345). This humidifier has a rotor humidifier 2 constructed of a silica gel adsorbent, zeolite or the like, arranged in a box 1. An absorption step of humidity 3 and a humidification step 5 extend through this humidifier rotor 2. The humidifier rotor 2 performs a moisture absorption operation in the moisture absorption step 3 and performs a moisture desorption operation in the passage of humidification 5. A fan 6 is arranged on the side located upwards of the humidifier rotor 2 of the absorption step of humidity 3 in order to make an air flow as indicated by the arrows A and B, so humidifier rotor 2 absorbs moisture of the air in the moisture absorption step 3. On the other hand, a fan 7 and a heater 8 are arranged on the side located upwards of humidifier rotor 2 of humidification step 5 in order to make an air flow as indicated by arrows C and D through the humidification step 5. The air, which is located in the humidification step 5 is fed with pressure by the fan 7 and heated by heater 8, is humidified by the humidifier rotor 2 (absorbing moisture from the humidifier rotor 2) and supplied to an indoor unit through a tube (not represented).

In this humidifier, the humidifier rotor 2 absorbs moisture from the air in the moisture absorption step 3 and the moisture is discharged from the humidifier rotor 2 into the air in the passage of humidification 5. This provision has the advantage that it is not No water supply unit needed.

However, in said humidifier conventional, the fan 6 in the moisture absorption step 3 and the fan 7 in the humidification step 5 is located in the upward side of the humidifier rotor 2, and consequently, this provision has the following problems. In general, a large amount of air flows (3 m3 / minute, per example) through the moisture absorption step 3 in order to collect air humidity. The moisture absorption step 3 has a relatively large cross-sectional area, and fan 6 apply enough pressure to simply make the air pass through the humidifier rotor 2. Therefore, a pressure at a point M on the upward side of the rotor humidifier 2 in the moisture absorption step 3 is approximately 7 mm water column pressure. On the other hand, a relatively small amount of air is supplied (0.2 m 3 / minute, for example) to the humidification step 5. The area in cross section of the humidification step 5 is relatively small, and a pressure at a point L on the side down of humidification fan 2 in humidification step 5 is 50 to 80 mm water column pressure in order to overcome the long tube resistance to the indoor unit on the side of the passage of humidification 5. Consequently, there is the problem that the pressure difference between point M and point L is approximately 43 to 73 mm of water column pressure and large amount of humidified air in the humidification step 5 escapes to the moisture absorption step 3. The humidifier rotor 2 rotates around an axis 2a, and therefore, there is an interval between a wall 9 and the humidifier rotor 2 with the wall 9 located between points L and M. Large amount of humidified air escapes through of this interval by said large pressure difference. Because this escape from humidified air produces an efficiency of degraded humidification (amount of humidification / input).

Summary of the Invention

According to the present invention, a humidifier including: a humidifier rotor, a step of moisture absorption that extends through the rotor humidifier, a moisture absorption fan arranged in the moisture absorption step, a humidification step that extends through the humidifier rotor, a fan of humidification arranged in the humidification step and means of heating to heat air in the humidification step, the humidifier rotor absorbs air moisture in the absorption step of humidity and humidifies the heated air in the passage of humidification, where the humidification step is next to the step of moisture absorption by means of a portion of outside air near the humidifier rotor.

In the humidifier that has the construction above, the humidification step is next to the absorption step of moisture through the portion of outside air near the rotor humidifier Therefore, the pressure difference between the passage of humidification and the outside air portion can be made smaller that the pressure difference between the humidification step and the moisture absorption step. Therefore, the dry air intake The humidification step can be reduced. Therefore, the Humidification efficiency can be improved.

In the humidifier of an embodiment of the In the present invention, a humidifier is provided as described above, where the humidification fan looks at a passage portion of the humidification step by means of the rotor humidifier and does not look at the outside air portion.

In the previous embodiment, the fan of humidification looks at the step portion of the humidification step using the humidifier rotor and does not look at the air portion Exterior. Therefore, even if the outside air flow is from the outside air portion to the passage portion of the passage of humidification, outside air does not flow to the fan of humidification directly through the humidifier rotor without pass through the passage portion. Therefore, the amount of outside air that enters directly into the fan of humidification of the outside air portion can be reduced, by what flows a greater amount of air heated by the heater through the humidifier rotor, which allows to improve the humidification efficiency

In other embodiments of the present invention, the humidifier of the invention is constructed so that the moisture absorption fan is arranged in the step of moisture absorption on the downward side of the rotor humidifier; and the humidification fan is arranged in the humidification step on the downward side of the rotor humidifier

In the humidifier that has the construction above, the moisture absorption fan and the fan of humidification are arranged on the side located down the humidifier rotor The humidification step and the step of moisture absorption have negative pressures near the end surface of the humidifier rotor and do not have a high positive pressure such as humidified air to feed with pressure on the outlet side of the humidification fan. By therefore, the pressure difference between the air in the passage of humidification and air in the moisture absorption step or between the air in the humidification step and the outside air is small near the end surface of the humidifier rotor, so that the air leakage from the humidification step or the outside air inlet to the humidification step. Therefore, it Improves humidification efficiency.

In addition, in these embodiments, the step of humidification is next to the moisture absorption step by the portion of outside air near the humidifier rotor, and so Thus, the pressure difference between the air in the passage of humidification and the air in the outside air portion can be make less than the pressure difference between the passage of humidification and moisture absorption step. Therefore the exhaust between the outside air portion and the humidification passage It can be reduced. In addition, neither the humidification side nor the side of moisture absorption is influenced by fluctuations in pressure on the counterpart side. Therefore, you can keep a constant flow at each step, and performance is stabilized.

In a first modification of this embodiment, a portion of the humidifier rotor from which moisture is desorbed by air that is located in the humidification passage and is heated by heating means, it is preheated by air circulating to humidify through the portion, and the air preheated is heated by the heating means and passed through the humidifier rotor.

In the first modification of the embodiment, the portion of the humidifier rotor from which moisture is desorbed by the air heated by the heating means, is preheated by the circulating air to humidify through the portion, and to then the preheated air is heated by the means of heating. Therefore, the loading of the heating means is reduced, allowing the heating means to be Compact and save energy. In particular, by virtue of the cooperating effect of the provision that the air escape from the humidification step or air escape to the humidification step It is small and said preheating, humidification efficiency It is greatly improved.

In another modification of this embodiment, the moisture absorption fan and humidification fan They are arranged on one and identical side of the humidifier rotor.

In this other modification of the embodiment, the moisture absorption fan and humidification fan They are arranged on one and identical side of the humidifier rotor. By Therefore, the dimension of the entire humidifier in the direction axial humidifier rotor is smaller than in the case where They have humidifier rotor on both sides. Therefore, it you get a humidifier that has a small, high air leak Humidification efficiency and a compact body.

In another modification of this embodiment, a heater that serves as the heating means is arranged in the humidification step on the upper side of the rotor humidifier, and the humidification fan is arranged in the bottom side of humidifier rotor.

In this additional modification of the embodiment, the heater is arranged on the upper side of the rotor humidifier, and therefore, the heater does not leak electrical even if dew condensation occurs in the rotor humidifier or the like. The air heated by the heater is sucked into the bottom side of the humidifier rotor by the humidification fan.

In another modification of this embodiment, a engine to move the humidification fan has a box whose lower portion is provided with a hole.

In this additional modification of the embodiment, water droplets generated by condensation of dew on the humidifier fan motor case are discharged through the hole in the box. Therefore the engine Do not experience stop. This provision also eliminates the noise generation and component deterioration due to Water.

In another modification of this embodiment, It has a protective cover near the hole of the box.

Description

As depicted in figure 1, this humidifier has a 12 shaped disc humidifier rotor arranged in a box 10. This humidifier rotor 12 is constructed forming an adsorbent of silica gel, zeolite, alumina or analogues, for example, similar to honeycomb or a form microporous multiparticles and is spun by an engine (no represented) around an axis 12a. Box 10 is divided internally by a dividing plate 11, forming a step of moisture absorption 13 and a humidification step 15 that extend through the portions of the humidifier rotor 12.

An absorption side fan motor of moisture 14 is disposed on the downward side of the rotor humidifier 12 and on the bottom side of the humidifier rotor 12 in the moisture absorption step 13, producing an air flow through air intake as indicated by arrow A. Although not represented, this moisture absorbing side fan motor 14 is consisting of a moisture absorption fan (called a moisture absorption fan in the meaning of a fan located on the side of the moisture absorption step) and a engine to move this moisture absorption fan that are integrated into a unit The humidifier rotor 12 absorbs moisture (adsorbs water) from the air flowing in the direction of arrow A a through the moisture absorption step 13. In the absorption step of humidity 13, a pressure at a point S on the side located towards above the humidifier rotor 12 is approximately 0 mm pressure of water column, and a negative pressure at a point M on the side located down the humidifier rotor 12 is approximately -7 mm water column pressure.

Moreover, a side fan motor of humidification 17 is arranged on the side located down of the humidifier rotor 12 and on the bottom side of the rotor humidifier 12 in the humidification step 15, producing a air flow by air aspiration as indicated by arrow B. Although not shown, this humidification side fan motor 17 is made up of a humidification fan (called a humidification fan in the meaning of a fan located on the side of the humidification step) and a motor to move this humidification fan that are integrated into a unity. A heater 16, which serves as an example of means of heating, is arranged in a portion above the rotor humidifier 12 in the humidification step 15, so that the air that has a temperature of 100 ° C or more heated by this heater 16 be humidified by the humidifier rotor 12 (the humidifier rotor 12 desorbs moisture) while passing through the humidifier rotor 12. The air flowing through the humidification step 15 passes twice through the rotor humidifier 12 in a passage portion 15u located on the side located up and a portion of step 15d located on the side located down the heater 16. An upward air flow Bu that passes first through the humidifier rotor 12 collects humidifier rotor heat 12, and a downward air flow Bd which has collected said heat and is also heated by the heater 16 at a temperature of 100 ° C or more absorbs moisture from the rotor humidifier 12. That is, as depicted in Figures 2 and 3, the humidifier rotor 12 rotates in a direction indicated by the arrow R, successively moving a portion 12A that looks at the passage of moisture absorption 13, a portion 12Bd that looks at the portion of step down 15d of the humidification step 15 and a 12Bu portion looking at the upward 15u step portion of the humidification step 15. As shown in Figure 3, the moisture absorbed by the humidifier rotor 12 of the air A in the moisture absorption step 13 is desorbed by air Bd which has a temperature of 100 ° C or more heated by heater 16 and goes to the lower side of the humidification step 15, so that this air Bd is humidified.

The air thus humidified Bd is sucked by the humidification side fan motor 17 represented in the Figure 1, then fed with pressure so that it has a positive pressure of 50 to 80 mm of water column pressure in the tube inlet 19 overcoming the resistance of the long tube 19, and fed to a room through an indoor unit (no represented). This humidifier is installed in a unit outside (not shown), and therefore, the tube 19 connected to The indoor unit is considerably long. In the passage of humidification 15, a negative pressure at a point L on the side located above the humidifier rotor 12 is approximately -3 mm water column pressure, and a negative pressure in a point N on the downward side of the humidifier rotor 12 is approximately -6 mm water column pressure.

On the other hand, as represented in the Figures 2 and 3, the air located upwards Bu to humidify passes to through the 12Bu portion of the humidifier rotor 12, which has been heated by the heated air and from which the humidity, preheating the air Bu by the heated portion 12Bu. From another point of view, this preheating means the cooling of the 12Bu portion of the humidifier rotor 12 by the air Bu before the 12Bu portion looks at the absorption step of humidity 13, and therefore, the humidifier rotor 12 can absorb sufficiently moisture in the moisture absorption step 13.

The air flow Bu and the air flow Bd are countercurrent flows, and therefore, the thermal gradient of the air flow Bu and the thermal gradient in the thickness direction of the humidifier rotor 12 are identical, allowing the flow Builder collect heat efficiently from the humidifier rotor 12.

As shown in Figure 1, the box of the humidification side fan motor 17 is provided with a hole 21 in its lower portion, which discharges water drops condensed in this box through hole 21. With this arrangement, the engine does not experience shutdown. This arrangement it also eliminates noise generation and deterioration of components due to water. In addition, a cover has been arranged protective 22 near the hole 21 of the box, so that if it comes out steam through hole 21, steam is prevented from splashing others components to be interrupted by the protective cover 22.

It should be noted that reference numbers 31, 32 and 33 denote divisions in Figure 1.

In the humidifier that has the construction above, a portion located in the moisture absorption step 13 of the humidifier rotor 12 adsorbs moisture from the air in the passage of moisture absorption 13. In the humidifier rotor portion 12 which has adsorbed moisture, moisture is desorbed by air Bd heated to a temperature not lower than 100 ° C by heater 16 in the step portion 15d directed to the lower side of the passage of humidification 15 (Bd air absorbs moisture). As described previously, the air Bd that has absorbed moisture from the rotor humidifier 12, that is, the humidified air Bd is driven by the humidification side fan motor 17 so that have a positive pressure of 50 to 80 mm at the inlet of tube 19 to overcome the resistance of the long tube 19 that extends to the indoor unit

The portion of the humidifier rotor 12, which has been heated by the heated air Bd and from which the moisture, preheats the air Bd to humidify that flows through step portion 15u when it is in step portion 15u directed to the upper side of the humidification step 15. This air preheated Bu is heated by heater 16 and is the flow of air down Bd to be supplied to the humidifier rotor 12 and humidify As described above, the air Bu se preheat using the heat of the heated humidifier rotor 12, and therefore, heater 16 may have a reduced load, Be compact and save energy.

The absorption side fan motor of humidity 14 and humidification side fan motor 17 they suck air while they are located on the side located down of the humidifier rotor 12, and therefore, the air has a negative pressure or approximately zero pressure near the rotor humidifier 12. That is, in the moisture absorption step 13, the pressure at point S on the bottom side of the humidifier rotor 12 is approximately 0 mm of water column pressure, and the pressure at point M on the upper side of the humidifier rotor 12 It is -7 mm water column pressure. In the humidification step 15, the pressure at point L on the upper side of the rotor humidifier 12 is -3 mm water column pressure, and the pressure at point N on the bottom side of the humidifier rotor 12 It is -6 mm water column pressure. Therefore a difference pressure between point L and point M on the upper side of the humidifier rotor 12 is 4 mm = (-3 mm - (-7 mm)) pressure Water column, which is small. Therefore, the air leakage of the humidification step 15 to moisture absorption step 13 a through point L and point M is small. In addition, the difference of pressure between point S and point N on the bottom side of the rotor humidifier 12 is 6 mm = (0 mm - (- 6 mm)) column pressure of Water, which is small. Therefore, the air escape from the passage of moisture absorption 13 to the humidification step 15 through the point S and point N is small.

As described above, the escape of air between the moisture absorption passage 13 and the passage of humidification 15 is small, and therefore, the efficiency of humidification (amount of humidification / input) is improved considerably. In particular, by virtue of the cooperative effect of this small exhaust and the preheating of air to humidify by the humidifier rotor 12, the humidification efficiency is improved very much.

In the present embodiment, the engine of moisture absorption side fan 14 and the motor humidification side fan 17 are arranged on the side bottom, or the same side with respect to the humidifier rotor 12, and therefore, the dimension in the axial direction of the rotor humidifier 12 of the entire humidifier can be reduced. How I know represented in the example of the prior art in figure 5, if the fan 6 of the moisture absorption step 3 is arranged in a side of the humidifier rotor 2 and the fan 7 of the passage of humidification 5 is arranged on the other side of the humidifier rotor 2, fans 6 and 7 are arranged on both sides of the rotor humidifier 2, leading to an increase in the dimensions of everything the device

Figure 4 represents a humidifier like the claimed in the invention. The embodiment represented in the figure 4 differs from the embodiment represented in figure 1 in that a portion of outside air 55 that communicates with outside air It is formed by walls 51 and 52 of a box 50 and the passage of moisture absorption 13 and humidification step 15 do not communicate directly with each other, but through the air portion outside 55 above the humidifier rotor 12. Therefore, the same components as those of the embodiment of figure 1 are designate with the same reference numbers omitting their description, and only those described below different components.

In the moisture absorption step 13 represented in figure 4, the pressure at point M on the side Top humidifier rotor 12 is -7 mm column pressure of water. In the humidification step 15, the pressure at point L on the upper side of the humidifier rotor 12 is -3 mm pressure of water column. A pressure at a point Q of the air portion Outside 55 is naturally 0 mm of water column pressure. Therefore, the pressure difference between point Q and point L on the upper side of the humidifier rotor 12 is 3 mm = (0 mm - (-3 mm)) of water column pressure, which is less than 4 mm pressure of water column of the embodiment of Figure 1. As has been described above, the pressure difference between point Q of the outside air portion 55 and the point L of the passage of humidification 15 has the small value of 3 mm pressure of water column, and therefore, the amount of air entering the humidification step 15 of the outdoor air portion 55 is little. In addition, the pressure in the outdoor air portion 55 is more high than the pressure near the humidifier rotor 12 in the passage of humidification 15, and therefore, the heated air does not escape the humidification step 15. Therefore, the efficiency of Humidification is greatly improved. In particular, by virtue of the effect cooperative of the small exhaust and the preheating of the air to humidify by the humidifier rotor 12, the efficiency of Humidification is greatly improved. Also, neither the side of humidification nor the moisture absorption side is influenced by pressure fluctuations on the counterpart side. For the Therefore, a constant flow can be maintained at each step, and stabilizes performance

The embodiment depicted in Figure 6 differs from the embodiment represented in figure 4 in the Humidification side fan motor arrangement 57 and it is identical to the embodiment of figure 4 in the other points. By therefore, the same components as those of the realization of the Figure 4 are designated with the same reference numbers omitting its description, and will only be described to Then the different components.

In this embodiment of Figure 6, the engine of humidification side fan 57 looks at a passing portion 15d on the upper side of the humidification step 15 by means of the humidifier rotor 12 and does not look at the outside air portion 55. Therefore, although the outside air flowing through point Q of the outdoor air portion 55 enters the passage portion 15d of the humidification passage 15 on the upper side of the rotor humidifier 12, the outside air does not flow directly to the engine of humidification fan 57 directly through the rotor humidifier 12. Therefore, the amount of air can be reduced which enters from the outside air portion 55, and can be done pass a larger amount of air heated by the heater 16 to through the humidifier rotor 12, the efficiency can be improved of humidification

Although heater 16 is used as the heating means in said embodiment, it is acceptable to use the exhaust heat from outdoor unit compressor or other means heating, such as microwave instead of this heater 16.

Although this humidifier is installed in the outdoor unit of the air conditioner and humidified air is driven from the indoor unit in said embodiment, it is possible, Naturally, use this humidifier separately. Although in bliss embodiment the fan motors 14 and 17 are used which are obtained by integrating a fan and an engine, it is acceptable to employ a fan and a separate bodies engine.

In the realizations where the passage of humidification is directly adjacent to the absorption step of humidity near the humidifier rotor, the pressure difference between the air in the humidification step and the air in the passage of Moisture absorption is small near the end surface of the humidifier rotor. Therefore, the air escape from the passage of humidification is small although the humidification step is directly adjacent to the moisture absorption step near the humidifier rotor

An advantage that is achieved with this invention is to provide a humidifier that has a small amount of air leakage between its humidification step and its passage of moisture absorption and has high efficiency of humidification
