[Industrial applications]

 The present invention relates to the structure of a humidifier for an air conditioner.

[0002]

[Prior art]

 Conventionally, a humidifying element of an air conditioner is configured by arranging a plurality of humidifying plates (porous plates) linearly with respect to a spacer. As a document disclosing a humidifier equipped with such an element, there is JP-A-1-174835. Hereinafter, the configuration of the humidifier will be briefly described with reference to FIGS. 4 to 6.

First, FIG. 4A is a perspective view showing a configuration of an element of a humidifier, and FIG. 4B is a plan view thereof. The element is composed of a plurality of humidifying plates 15 and a spacer 18. As shown in FIG. 4 (b), the spacer 18 has a comb shape, and a recess provided on the water supply unit 25 side of the humidifying plate 15 is fitted into the recess. By combining the spacers 18 and the humidifying plates 15 as described above, the humidifying plates 15 are arranged in a line.

Next, FIG. 6 is a perspective view showing a configuration of the humidifier 14. The main components of the humidifier 14 are the humidification plate 15, the water supply tank 16, and the drain tank 17 having the above-described structure. That is, the water supply unit 25 of the humidifying plate 15 is immersed in the water supply tank 16. This is realized by fitting the edge of the water supply tank 16 into the slit 26 provided in the humidifying plate 15. The humidifying water in the water supply tank 16 is supplied from the hole 24 of the water supply pipe 23 through the water pipe 20, the electromagnetic valve 21, and the water supply pipe 23. At that time, the humidifying water is sucked up to the humidifying section 27 of the humidifying plate 15 by the capillary action of the humidifying plate 15.

On the other hand, FIG. 5 is a vertical view showing a configuration of a ceiling-embedded air conditioner (hereinafter simply referred to as an air conditioner) in which the humidifier 14 is incorporated. As shown in the figure, the humidifying part 27 of the humidifying plate 15 is arranged in the ventilation passage 13 for the air discharged from the heat exchanger 6, and the humidifying part 27 is close to the heat exchanger 6 in a face-to-face manner. Has been done. Other components in the air conditioner body 1 include a heat exchanger heater 7, a blower 8, a fan 9 and a drain pan 12. Further, a decorative panel 5 that covers the opening of the ceiling surface 2 is installed on the lower surface of the main body 1, and the air outlet 4 provided in the decorative panel 5 is connected to the ventilation passage 13.

[Problems to be solved by the device]

 However, curved air heat exchangers are used in air conditioners that have outlets in multiple directions. Therefore, when the humidifier element is placed near the heat exchanger, the effective area of the element in the ventilation passage (the area occupied by the element in the cross-sectional area of the ventilation passage through which the discharge air actually passes) becomes insufficient. However, there was a problem that the humidification capacity was insufficient. FIG. 7A is a diagram schematically explaining this problem.

As a method of solving this problem, it is conceivable to increase the number of humidifiers (for example, use two humidifiers for each air conditioner) according to the shape of the curved heat exchanger. However, this solution causes a new problem that deteriorates the workability of the air conditioner.

On the other hand, a solution in which the element is appropriately divided according to the shape of the heat exchanger can be considered. For example, as shown in FIG. 7B, the element is divided and arranged into three elements E1 to E3 along the outer circumference of the heat exchanger. This division will certainly make it possible to replenish the lack of humidification capacity. However, due to the element division, the number of parts is increased, and as a result, the number of assembling steps is increased. This is in reverse to the current trend of air conditioner technology, which requires the reduction of assembly man-hours.

The present invention has been made in view of the above problems, and it is possible to improve the humidifying capacity of an air conditioner using a curved heat exchanger without increasing the number of parts and the number of assembly steps. It is intended to provide a humidifier having a different structure. At that time, we also intend to realize a humidifier that can flexibly cope with the curved shape of the heat exchanger.

[0010]

[Means for Solving the Problems]

 A first configuration of the present invention comprises an element arranged in a ventilation air passage for discharge air facing a curved heat exchanger of an air conditioner, and further, the element is (a) two curved And (b) a humidifying plate having a recess for inserting each spacer.

A second configuration of the present invention comprises an element arranged in the discharge air ventilation passage facing the curved heat exchanger of the air conditioner, and further, the element is (a) a bent portion. It is provided with two free spacers and (b) a humidifying plate having a recessed portion into which the respective spacers are fitted.

A third configuration of the present invention relates to the first or second configuration, in which the element is close to the curved heat exchanger.

A fourth configuration of the present invention relates to the first to third configurations, in which a part of the humidifying plate is immersed in a curved water supply tank.

[0014]

[Action]

 In the first configuration of the present invention, the humidifying plate is curved by the two spacers fitted in the recessed portion.

In the second configuration of the present invention, the humidifying plate is curved according to the degree of curvature of the two spacers fitted in the recessed portion.

In the third configuration of the present invention, since the element is close to the curved heat exchanger, the element effectively occupies the space in the ventilation passage. As a result, the area of the element in the ventilation passage increases.

In the fourth configuration of the present invention, not only the element but also the water supply tank effectively occupies the space in the ventilation passage.

【Example】

 FIG. 1 is a perspective view showing a configuration of an element 40 of a humidifier which is an embodiment of the present invention. As shown in the figure, the element 40 is composed of two spacers 42 and 44 and a plurality of humidifying plates 41. Here, the two spacers are made of resin such as plastic and can be curved within its elastic range.

On the other hand, each humidifying plate 41 is provided with three slits 43, 45 and 46. Among these, two slits 43 and 45 are for fitting the above-mentioned spacers 42 and 44, respectively, and the remaining slits 46 are for fitting the outer edge of the water tank 1650 which will be described later. It is a thing.

By using the spacers 42 and 44 and the humidifying plate 41 having such a configuration, the present element 40 can be easily curved. That is, the two spacers 42, 44 are appropriately curved according to the curvature of the heat exchanger, and the spacers 42, 44 are arranged in parallel in this curved state, and the slits 43, 45 of all the humidifying plates 41 are arranged. By inserting the spacers 42 and 44 into the above, the curved element shown in FIG. 1A can be constructed. Here, it is assumed that the two spacers 42 and 44 are resin plates that are curved (flat plates in normal times), but of course, those that are molded in advance into a curved shape having an appropriate radius of curvature may be used. It can also be used as the spacer.

Next, the curved shape as shown in FIG. 1A is set, and the curved shape is set in the water tank 50. This setting is performed by fitting the arc-shaped outer edge 51 of the water supply tank 50 into the slit 46 of the humidifying plate 41. As a result of this fitting, the water supply part 47 of the humidifying plate 15 is immersed in the humidifying water (not shown) in the water supply tank 50. As a result, the humidifying water is sucked up to the humidifying section 48. This point is as described in the related art.

FIG. 2 is a plan view schematically showing a state in which the present element 40 (set in the water supply tank 20) is arranged close to the curved heat exchanger 6. Since the elements 40 can be arranged along the outer periphery of the heat exchanger 6 in this manner, the effective area occupied by the elements 40 in the ventilation passage 13 is significantly increased as compared with the conventional elements. . This naturally leads to an improvement in the humidifying capacity of the humidifier. Although not shown in the figure, the other components except the humidifier in this embodiment are the same as the respective components shown in FIG. Although not shown, the humidifier also includes a water supply pipe 23, a hole 24, and the like, like the humidifier shown in FIG. Here, FIG. 3 shows an example of a humidifier to which the element 40 shown in FIG. 1 is applied. That is, a plurality of curved elements 42A, 42B, 42C, ... Are incorporated into the humidifier, and the humidifier is bent multiple times. With such a configuration, it is possible to realize a humidifier capable of coping with a heat exchanger having an arbitrary shape without deteriorating the humidifying capacity.

It should be noted that the two spacers 42 and 44 do not necessarily have to be arranged in the facing spacers 43 and 45 as shown in FIG.

[0024]

[Effect of device]

 In the first configuration (Claim 1) of the present invention, the element can be easily curved in accordance with the curvature of the spacer. Therefore, even if the heat exchanger is curved, the effective area of the element can be increased, and as a result, the humidifying ability can be increased. Moreover, it does not increase the number of air conditioner parts or the number of assembly steps.

Further, in the second configuration (claim 2), in addition to the above effect, there is an effect that the curvature of the element can be set so as to best suit the shape of the heat exchanger according to the shape thereof. The effect makes it possible to further improve the humidifying ability.

Moreover, in the third configuration (claim 3), since the element is arranged close to the heat exchanger, the effective area of the element can be further increased, and the humidifying ability can be significantly improved.

Further, in the fourth configuration (claim 4), the water supply tank can also be arranged according to the shape of the curved heat exchanger, and the humidifier can effectively occupy the inside of the ventilation passage. .
