る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle humidifier for adjusting the atmosphere in the interior of a vehicle such as an automobile, which is particularly compact and has no risk of leaking water even in an inclined state. It relates to a humidifier.

Although there are various types of humidifiers, for example, water is stored in a water supply pan, and a plurality of humidification plates made of a highly water-absorbent resin material are erected on the water supply pan at intervals with a space between the humidification plates. There is a system in which the circulating air contains water.

ている。The humidifier of the above system is usually incorporated as a dust collector, a heat exchanger, etc., and is often used as an air conditioner for offices. On the other hand, for home use or office use in a small space, an ultrasonic humidifier that emits fine water droplets into the air by ultrasonic vibration is also widely used.

利である。Next, the cabin of an automobile is extremely dry especially in winter, and the humidity may be 10% or less.
Therefore, particularly in the cab of a truck for long-distance transportation, a small and compact humidifier is desired in order to maintain good occupant health. As such an on-vehicle humidifier, a method of circulating between humidifying plates is more usable than an ultrasonic type humidifier because there is no scattering of chlorine, germs, and less clouding of windows due to supersaturated water. It is advantageous as an on-vehicle humidifier that is narrow and secures visibility.

合によっては不可能であるという問題点がある。However, in the system in which air is circulated between the humidifying plates, the humidifying capacity depends on the surface area of the humidifying plates, so that the humidifying plate tends to be large in size. In addition, one end of the humidifying plate must be located in the water, and the other part must be located in the air flow passage, so a water supply pan is required. In the case of a cab-tilt type vehicle in which the driver's cab is tilted for maintenance and inspection, the means to prevent water leaks in the water supply pan is complicated, and in some cases impossible. There is a point.

ように構成する。In order to solve the above problems, for example, FIG.
Also, a drip water supply type humidifier as shown in FIG. 5 has been proposed. 4 is a front view and FIG. 5 is a left side view. In FIGS. 4 and 5, reference numeral 21 denotes a humidifying plate, which is formed of a highly water-absorbent resin material in a flat plate shape, and a plurality of which are erected at intervals with a support member 22 interposed therebetween. A water supply pipe 23 is arranged above the humidifying plate 21. A small hole is formed in the lower surface of the water supply pipe 23 so that the water supplied from the water supply tank 24 via the pump 25 can be supplied to the humidification plate 21. Reference numeral 26 denotes a sensor, which is provided on the humidifying plate 21 and is configured to be capable of intermittently driving the pump 25 via a control circuit (not shown).

せるのである。With the above structure, if the air is circulated between the humidifying plates 21 by the fan 27 as shown by the arrow, the humidifying plate 2
The moisture of No. 1 can be contained in the circulating air, and by releasing this air into the passenger compartment, the inside of the passenger compartment can be maintained in an atmosphere of appropriate humidity. Then, the sensor 26 detects the water content of the humidifying plate 21, and when the water content is less than the predetermined value, the pump 25 is driven through the control circuit to supply the water from the water supply tank 24 to the water supply pipe 23 to drop the water on the humidifying plate 21. is there.

という利点がある反面において、下記のような問題点が
ある。Since the vehicle-mounted humidifier having the above-mentioned structure does not use the water supply pan having an open upper side as in the humidifier for office, water leakage in the case where the vehicle or the passenger compartment is inclined. Although there is an advantage that it is not necessary to provide a preventive means, there are the following problems.

となるという問題点がある。First, the amount of water supplied to the humidifying plate 21 is, of course, kept in a wet state, but it is necessary to control the amount of water so that excess water does not drip downward from the humidifying plate 21. . Therefore, it is necessary to control the amount of water supplied from the pump 25 to the water supply pipe 23 with high accuracy, and the control circuit and the control device are indispensable components, resulting in an increase in size and cost.

ととなり、車室内を汚染することとなる。A sensor 26 is provided to detect the wet state of the humidifying plate 21, but the sensor 26 is usually provided only on a specific humidifying plate 21 of the plural humidifying plates 21. Also, there are variations in the wet state of the plurality of humidifying plates 21. Therefore, some of the humidifying plates 21 have an insufficient amount of supplied water, which may result in insufficient humidifying action on the circulating air. On the other hand, if the amount of supplied water is excessive, excess moisture will drip from the humidifying plate 21, which will contaminate the vehicle interior.

う問題点もある。It is also troublesome to keep the amount of water dropped from the water supply pipe 23 uniform for each humidifying plate 21,
There is a problem that the amount of supplied water varies.
On the other hand, in order to eliminate the above variations, it is necessary to manufacture each component with high accuracy, and a large number of man-hours and time are required for assembling, which causes a problem that manufacturing cost rises.
【００１２】本発明は、上記従来技術に存在する問題点

た。In order to achieve the above object, according to the present invention, a flat plate made of a highly water-absorbent resin material is formed in a humidifying chamber having a bottom portion capable of accommodating water and being hermetically sealed. A plurality of humidifying plates are installed upright at intervals such that their lower ends are located in the water, and an intake pipe and an exhaust pipe are projected on the upper surface of the humidifying chamber so that their lower ends project into the humidifying chamber. Therefore, a technical means is adopted in which the air from the blower is configured to flow from the intake pipe to the exhaust pipe through the space between the humidifying plates.

ができるのである。With the above construction, since the lower end of the humidifying plate is always located in the water, it absorbs an appropriate amount of water by the capillary action, so that its surface can be kept in a wet state, and the space between a plurality of humidifying plates can be maintained. The above-mentioned wet state in 1 is maintained uniformly, and variations are eliminated. On the other hand, since the lower end portions of the intake pipe and the exhaust pipe are formed so as to project into the humidification chamber, the water stored in the humidification chamber leaks to the outside even when the vehicle or the vehicle interior is inclined. It is possible to prevent the occurrence of such an undesired situation.

を防止できる。In the above case, assuming that the amount of water 10 is V and the bottom area and side area of the humidification chamber 2 are A 1 and A 2 , respectively, V = A 1 h 1 = A 2 h 2 Since h 2 = (A 1 / A 2 ) h 1 , the water level rises only slightly as shown in FIG. 3 (b). Since both the intake pipe 6 and the exhaust pipe 7 are formed so that the lower end portions thereof project into the humidification chamber 2, the water 10 will be absorbed by the intake pipe 6 and the exhaust pipe even if the water surface of the water 10 swings. No water leaks into 7. The intake pipe 6 and the exhaust pipe 7
As shown in FIG. 3, the protrusion size of the humidification chamber 2 is appropriately selected in consideration of the amount of stored water.
It is possible to prevent the water 10 from leaking even when it is turned upside down as in (c).
