JPS62242742A - Evaporation type cool air fan - Google Patents

Abstract

PURPOSE:To obtain a cool air temperature desired by an user by a method wherein a flow passageway, in which suction air does not pass through a humidifying filter, is formed and an opening and closing device, which controls the amount of suction air at an air suction port forming said flow passageway, is provided in the titled fan. CONSTITUTION:When a motor 4 is connected to a power source, vanes 6 are revolved and air is sucked through both of an air suction port 9, which forms a flow passageway passing through a humidifying filter 3, and another air suction port 10, which forms the flow passageway not passing through the humidifying filter. The amount of air passing through the humidifying filter 3 is restricted, therefore, the amount of the humidification of the humidifying filter 3 is reduced whereby cooling air is diluted by the air from the air suction port 10. The degree of this dilution and the amount of humidification may be controlled by an opening and closing device 11, which controls the amount of suction air at the air suction port 10 forming the flow passageway which does not pass through the humidifying filter, whereby the cooling degree of blow-off air may be controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an evaporative cooling fan that generates cold air using the latent heat of vaporization of water.

2. Description of the Related Art Conventionally, this type of evaporative cooling fan has had a configuration as shown in FIG. That is, a water tank 13 is provided at the bottom of the outer frame 12, and water is stored in this water tank 13. A lower part of a humidifying filter 14 is disposed along the inner periphery of the water tank 13. Further, an electric motor 15 is installed above the water tank 13, and the lower end of the shaft of the electric motor 16 has its tip connected to the water tank 13.
A water suction pipe 16 inserted into the interior and supplying water to the humidifying filter 14
are connected to each other, and a blade 17 is connected to the upper end of the shaft of the electric motor 16. The blades 17 are covered by a casing 18 and are configured to blow air to an air outlet 19 formed in the casing 18 and located at the upper front surface of the outer frame 12. The air suction port 20 is provided around the humidifying filter 14 of the outer frame 12, and its air flow path is formed to pass through the humidifying filter 14 as shown in C.

With the above configuration, when power is supplied to the electric motor 16, the blades 17 rotate, and air is sucked in from the air intake port 20 of the outer frame 12 like the air flow path C, passes through the constant humidification filter 14, and blows air. It is blown out from the outlet 19. At this time, electric motor 1
The water suction pipe 16 connected to the lower end of the shaft of 6 rotates and supplies water to the humidifying filter 14. Therefore, when the sucked air passes through the humidifying filter 14, it is cooled by the latent heat of vaporization of water and constantly blows cold air. It's full of things to put out.

Problems to be Solved by the Invention In addition, in this conventional configuration, the air flow path C always passes through the entire humidifying filter 13 and is constantly cooled by the latent heat of vaporization of water. There was a problem that the air temperature could not be controlled, and in severe cases, the user felt discomfort due to excessive exposure to cold air. The present invention solves these problems and allows the user to obtain the desired cooling air temperature. The purpose is to

Means for Solving the Problems In order to solve this problem, the present invention forms all channels in which the intake air does not pass through the humidifying filter in an evaporative cooling fan, and also forms all channels in which the intake air does not pass through the humidifying filter. This configuration is equipped with an opening/closing device that controls the amount of air intake at the air intake port.With this configuration, when power is supplied to the electric motor, the blades rotate, forming a flow path that passes through the entire humidifying filter. Air is sucked in from both the air inlet, which forms a flow path that does not pass through the humidifying filter, and the air inlet, which forms a flow path that does not pass through the humidifying filter.As the amount of air that passes through the humidifying filter is restricted, the amount of humidification in the humidifying filter is reduced, and the The cooling air will be diluted by the air from the air intake that does not pass through the filter. Furthermore, the degree of dilution and the amount of humidification are controlled by the opening/closing device that controls the amount of intake air at the air suction port, which forms a flow path that does not pass through the humidifying filter, and the degree of cooling of the blown air is controlled.

EXAMPLE Below, an example of the present invention is shown in FIGS. 1 and 2. A tank is shown in FIGS. 6 is a blade connected to the upper end of the electric motor 4, 7 is a casing of the blade 6, and 8 is an air blower provided in the outer frame 1. The outlet 9 is the air suction port of the vane 6 that shadows the flow path Ai that passes through the humidifying filter 3 ft. Since these structures are similar to those of the conventional example described above, detailed explanation thereof will be omitted. . The feature of this embodiment is that a flow path Bi that does not pass through the humidifying filter 3 is formed, and an opening/closing device 11 for controlling the amount of intake air is provided at the air suction port 10 in this flow path.

In the above configuration, when the electric motor 4 is operated, the blades 6 rotate, and air is blown from the air outlet 8 of the Kussinga. At the same time, the water suction pipe 6 attached to the lower end of the shaft of the electric motor 4 rotates to supply water in the water tank 2 to the humidifying filter 3. At this time, the air taken in from the air suction port 9 as shown in the flow path A passes through the humidifying filter 3 and is cooled by the latent heat of vaporization of water. On the other hand, as shown in flow path B, air suction port 10
Since the air taken in from - has not passed through the humidifying filter 3, it is mixed with the cooling air at room temperature, diluting the temperature of the cooling air and increasing the temperature of the cooling air. Furthermore, since the amount of air taken into the blades 6 is almost constant, the amount of air is reduced to the amount that passes through the entire humidifying filter 3, and the amount of humidification in the humidifying filter 3 is also reduced.

Further, the degree of dilution and the amount of humidification can be controlled by controlling the intake air amount in the flow path B, and are controlled by the opening/closing device 11 installed at the air suction port 10.

Effects of the Invention As is clear from the description of the embodiments above, the present invention forms an air suction path that does not pass through the humidifying filter, in addition to the air suction path that does not pass through the humidifying filter. By adjusting the amount of suction, the user can freely choose the temperature of the air being blown out to their liking, reducing the discomfort caused by being exposed to cold air for long periods of time, and also making it possible to control the amount of humidification. can get.
