Description

  The present invention provides a new method for a cold air fan, which has a simpler structure, is more practical, and is easier to maintain than the conventional method. In addition, the present invention provides an inexpensive product while having both an air cleaning function and a humidifying function.

  FIG. 6 shows an example of the structure of a conventional cold air fan. In such a configuration, the belt-like filter a is hung on the upper and lower rollers b, and is rotated by the filter motor c installed on the upper roller b.

  The lower roller b is installed in the water of the water tank d, and the rotating filter a absorbs the water e of the water tank d and moves upward.

  The filter a is installed between the fan f and the intake port g. When the air taken in by the fan f passes through the filter a, the heat is taken away by the heat of vaporization caused by the evaporation of the water e, and the temperature drops. The cooled air is sent from the outlet h.

  In the conventional system, a blower motor i and a filter motor c are provided. Since a plurality of motors are used, there are many drive parts, which makes the assembly complicated and expensive.

  In the method of supplying water e to the vaporizing section, the filter a must absorb the water e and rotate the filter a to move to the air path. For this purpose, the lower roller b must be installed in the water tank d. Such a configuration is not easy to assemble and maintain.

  Furthermore, since the filter a is stretchable, it absorbs water and stretches to cause a problem of slippage.

  Since such a conventional method installs a filter a that is long in the vertical direction, the fan f, which is a blower, must also employ a vertically long sirocco fan. The sirocco fan not only makes it difficult to reduce the size of the product, but is also not the optimum blower for increasing the air flow.

  The filter a that has absorbed water is further reduced in air permeability and decreases the evaporation amount of the water e and the blowing effect. Therefore, the cooling effect cannot be sufficiently obtained due to the reduction of the evaporation amount and the blowing amount.

  In order to solve the above-mentioned problems, the present invention renews the structure of a conventional cold air fan. Conventionally, two motors are used for air blowing and filter rotation. In the present invention, air blowing and water pumping are performed with one motor.

  A blower fan is formed on one of the shafts of the motor and a pumping pipe for pumping is formed on the other, and the blower and the pump are simultaneously driven by one motor.

  In order to increase the air volume, the blower employs an axial fan that has better blowing efficiency than the conventional sirocco fan.

  The filter device employs a fine mesh made of resin such as nylon and is fixed. Two filter devices are set as a set, and a vaporizing unit is formed between them.

  According to the present invention, it is possible to provide an inexpensive product that realizes simplification of assemblability and maintainability and improves air blowing efficiency and vaporization efficiency.

  The present invention will be described below with reference to FIG. FIG. 1 shows an embodiment of the present invention and is a block diagram for explaining the arrangement of components.

  The pumping device includes a motor 1, a pumping pipe 2, and a sprinkler 3. The water sprinkling part 3 constitutes a space with a part of the pumping pipe 2 and the watering cover 4, and watering holes 5 for water spraying are formed. The lower part of the pumping pipe 2 reaches the water in the water tank 6.

  When the pumping pipe 2 connected to the lower side of the motor 1 is rotated, the water 8 is pumped upward by the spiral groove 7 formed in the pumping pipe 2. The pumped water 8 is sprinkled on the filter A9 by the sprinkler 3, and the sprinkled water 8 spreads in a film shape on the filter A9.

  Since the water 8 is continuously sprinkled, excess water 8 falls from the filter A9 and is sprinkled on the lower filter B10. Excess water 8 on the filter B 10 falls and is collected by the water receiver 11 and collected in the water tank 6.

  The filter A9 and the filter B10 are formed by a fine mesh 12 such as nylon and a frame body 13 that supports the fine mesh 12 and can be attached to the upper casing 14. A space formed between the filter A9 and the filter B10 serves as a vaporization section 15, and the temperature of air deprived of vaporization heat by the evaporation of the water 8 decreases.

  On the other hand, the blower is composed of a motor 1 and an axial fan 22. The axial fan 22 is directly connected to the motor 1.

  The axial fan 22 rotated by the motor 1 sucks air from the air inlet 18 and blows it to the vaporizer 15 to vaporize a part of the water 8 sprayed on the filter A9 and the filter B10. At this time, the blown air is deprived of vaporization heat and the temperature is lowered.

  The air whose temperature has been lowered is changed in air direction by the flat portion 16 of the water receiver 11, and the cooled air is blown from the outlet 17.

  Casing A14 arrange | positions the inlet 18 in the upper part, and arrange | positions the blower outlet 17 in the side surface center part. Inside the casing A14, there is a motor mount 19 for fixing the motor 1 to the upper part. A part of the motor mount 19 is a part of the air passage and forms an air hole 20.

  Filter A9, filter B10, and water receiver 11 are attached to casing A14 in a removable manner. Removable parts facilitate cleaning when dirty.

  When the water tank 6 needs water supply, the casing A14 can be detached from the casing B21 together with its internal components. The casing A14 has a sufficiently deep length with respect to the pumping pipe 2, and the pumping pipe 2 does not protrude from the casing A14.

  The water tank 6 is set in the casing B21 and is detachable from the casing B21. When water is supplied, the water tank 6 can be removed and water can be supplied directly from the water tap.

  The cold air fan of the present invention has renewed the conventional components, and the water vaporization device and the pumping device are simplified and can be miniaturized, and the performance is improved.

  Furthermore, the configuration of the present invention has an air cleaning function and a humidifying function. The air blown to the filter A9 and the filter B10 contains dust and odor. The water 8 sprayed on the filter A9 and the filter B10 adsorbs dust and odors and is collected in the water tank 6 as extra water 8 that does not evaporate. In addition, the air is humidified by the vaporizing unit 15 and is blown from the air outlet 17.

  It is a block diagram showing the basic composition of the cold air fan of this invention.   It is one Example of the external appearance of the cold air fan of this invention.   It is a top view of the water receiver of the Example of this invention.   It is sectional drawing of the water receiver of the Example of this invention.   It is a top view of the filter A of the Example of this invention.   It is a block diagram showing the basic composition of the conventional cold wind fan.
