Abstract

PROBLEM TO BE SOLVED: To provide an air cooler of a water evaporation type which can suppress decomposition of cooling water and generation of a bad smell and can send out cooled air being fragrant and having a refreshing and sanitary feel. SOLUTION: In regard to a cooler wherein air passing through a cooling element 3 is cooled by the latent heat of evaporation of cooling water 7 flowing down through the cooling element and the cooling water is sucked up from a water tank 6 by a pump 8 and sprinkled over the cooling element, the cooler is equipped with a means 10 for sterilizing the cooling water in the water tank and also with a perfume supplying device 14 which gives fragrance to the air having passed the cooling element 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an air conditioner cooler,
More specifically, the present invention relates to a water evaporation type air cooler.

[0002]

2. Description of the Related Art In a water evaporation type air cooler in which air passing through a cooling element is cooled by latent heat of cooling water flowing down the cooling element, cooling water from a water tank is cooled by the cooling element. Circulating water returning to the water tank via the
The cooling water in the water tank decomposes due to the propagation of various bacteria and microorganisms, generates an odor, and is unsanitary.

[0003]

[Object of the present invention] The present invention can suppress the decay of cooling water and the generation of offensive odor, and the cooled air is fragrant,
A water-evaporation type air cooler capable of delivering cool and hygienic air can be provided.

[0004]

In order to achieve the above object, in a cooler according to the present invention, air passing through a cooling element is cooled by latent heat of evaporation of cooling water flowing down the cooling element, and cooling water is supplied from a water tank. A cooler that is sucked up by a pump and sprayed on the cooling element includes means for sterilizing cooling water in a water tank.

More specifically, the cooling water sterilizing means is an ultraviolet lamp for irradiating the cooling water in the water tank with ultraviolet light, or an ozone generator for supplying ozone to the cooling water in the water tank. In addition, a perfume supply device that imparts aroma to the air that has passed through the cooling element is also provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to specific examples shown in accompanying drawings 1 to 5. In the figure, reference numeral 1 is a cooler,
2 shows the casing. A cooling element 3 and a blower 4 are provided in the casing, and the air taken in from the air inlet 5a on the rear side in the casing is cooled and temperature-controlled by the cooling element 3 and is blown by the blower 4 from an outlet 5b on the front face of the casing. Be blown out.

There are various types of cooling elements.
For example, a filter plate that allows air to pass through it and bends in a zigzag shape in the vertical direction with multiple layers arranged with a slight gap in the direction of air flow, or short fibers entangled to allow air to pass in the horizontal direction And those in which water can flow down in the vertical direction.

In the cooling element 3, cooling water 7 stored in a water tank 6 in a casing is sucked up by a pump 8, sprayed from above from a sprinkling pipe portion 9 a of a water supply pipe 9 to the element, and flows down in the element. At this time, the air passing through the element is cooled and flows down into the water tank 6, and the water in the water tank is pumped up by the pump, and the water is repeatedly sprayed from the water spray pipe section 9a to the cooling element.

In the present invention, the circulating cooling water supplied to the element is sterilized, and the air sent out of the casing has an aroma, coolness, and cleanness.

In order to sterilize the circulating cooling water, for example, an ultraviolet lamp 10 for sterilizing the cooling water in the water tank is provided in the water tank. At this time, the ultraviolet lamp is attached to an upper portion of the water tank or a portion located in the water so as to sterilize not only the surface of the cooling water in the water tank but also the water.

FIG. 2 shows an example in which the sterilizing means is an ultraviolet lamp. As shown in FIG. 3, ozone from an ozone generator 11 is supplied from an air supply pipe 12 to cooling water in a water tank, and the cooling water is sterilized by ozone. In some cases. In this case, an ozone decomposition catalyst 13 formed by processing activated carbon into a filter is provided on the air outlet side of the cooling element so that the allowable concentration of ozone in the working environment is 0.1 ppm or less.

FIG. 4 shows an example in which sterilization is performed by ultraviolet rays in addition to ozone, whereby sterilization can be performed more sufficiently.

In order to impart aroma to the cooling air, a fragrance such as peppermint or citrus is continuously or intermittently sprayed onto the air from the cooling element by the fragrance supply device 14 or dropped onto the evaporating dish 15. Or also FIG.
, The fragrance supply device 16 is connected to the water supply pipe 9 to the element.
Is connected by an air supply pipe 17, and the fragrance is supplied to the water in the water supply pipe 9 continuously or intermittently by a timer. In the case of intermittent supply, when supplying the cooling water to the water tank, the fragrance is supplied in conjunction with the liquid level detection by a liquid level detecting device (for example, a float) when the cooling water reaches the upper limit. To

[0014]

In the present invention, when the intake air passes through the cooling element, it is cooled by the latent heat of evaporation of the cooling water flowing down the element, and the temperature is blown out.

[0015] The cooling water supplied to the cooling element is circulating water. Since the circulating water is irradiated with ultraviolet rays or supplied with ozone, it is sterilized and sterilized, and the growth of bacteria is suppressed. Therefore, the cooling water is kept sanitary, rot and generation of bad smell are suppressed, and it can be used for a long time.

Further, since the fragrance is continuously or intermittently supplied to the air passing through the cooling element from the fragrance supply device, the fragrance drifts in the room to be cooled, thereby providing a refreshing feeling and a refreshing feeling. There are great things that contribute to improving mental and environmental health.
